`
`| Detailed Description
`
`
`
`
`
`[Detailed description of the invention]
`
`[Technical field]
`
`[0001]
`
`The present invention ferments and dries garbage inside a fermentation dry tub, r
`
`elates to the garbage disposal apparatus which decreases the quantity of garbag
`
`e, in detail, it is a simple structure, is low power consumption, advances fermenta
`
`tion for a short time, and is efficiency.
`
`To provide a garbage treating device which is suitable for use in which * garbage
`
`is reduced and reduced in weight.
`
`[Background of the Invention]
`
`[0002]
`
`

`

`https://www j-platpat.inpit.go.jp/p0200
`
`Various devices for reducing the amount of garbage using fermentation bacteria h
`
`ave been proposed and put into practical use.
`
`[0003]
`
`Conventionally, as described in, for example, Japanese Patent Laid-Open No. 200
`
`4 25170, a rotary blade for stirring garbage is installed in a treatment tank to the
`
`reby rotate a blade in order to ventilate garbage introduced into a fixed treatmen
`
`t tank.
`
`[0004]
`
`In this stirring method using the stirring blade, sufficient ventilation is not perfor
`
`med, and as a result, garbage is kneaded like a dumpling, so that the evaporatio
`
`n property of water is deteriorated, and the anaerobic fermentation is easily caus
`
`ed by excessive water.
`
`Further, since the torque for stirring is large, the driving device becomeslarge, le
`
`ading to a high cost, and the stirring time becomes long, so that the amountofel
`
`ectric use is large.
`
`[0005]
`
`In order to remedy this drawback, a method has been proposed in which the proc
`
`essing tank is a rotary drum. For example, as described in Japanese Patent Applic
`
`ation Laid-open No. 55 74786, a process tank is used as a rotary drum, and dust
`
`is introduced or discharged from a non-rotating side plate portion which forms a d
`rum.
`
`[0006]
`
`Further, as described in, for example, Japanese Patent Laid-Open No. 2004 - 141
`
`791, a process tank is also used as a horizontal rotary drum, and a hot air supply
`
`port for maintaining a fermentation temperature, a gas supply port for dischargin
`
`g generated water vapor or carbon dioxide gas, or a gas supply port for dischargi
`
`ng methane gas, and an exhaust port are configured so as to pass through a non
`
`-rotating side plate portion which forms a drum.
`
`[0007]
`
`Therefore, it is necessary to have a structure In which the body portion is rotated
`
`and the side plate portion is fixed, so that it has been necessary to adopt a struct
`
`ure in which the rotation receiving mechanism and the seal mechanism are place
`
`d between the two.
`
`[0008]
`
`In other words, in the horizontal rotary drum type garbage disposer, since only th
`
`e drum portion of the drum rotates and the side plate portion is fixed due to the a
`
`bove-described circumstances, a support roll mechanism and a seal mechanism h
`
`aving a large diameter which is equal to a diameter of the drum portion are requi
`
`red in order to support the weight of garbage inside the drum portion and the insi
`
`

`

`https://www.j-platpat.inpit.go.jp/p0200
`
`de of the drum portion and to support and support the drum portion.
`
`[0009]
`
`To solve the problem that a plurality of rotary rolls are required in a supportroll
`
`mechanism, and it is expensive to manufacture a large diameter seal mechanism
`with high cost, and it is very troublesome for maintenance.

`
`This garbage treating device is characterized in that the whole is covered with an
`
`outer skin.
`
`[0013]
`
`Further, according to the present invention, there is provided a garbage treatmen
`
`t apparatus according to claim 2.
`
`A moisture conditioner and a fermentation bacteria carrier are charged into the dr
`um.
`
`This method for treating a garbage is characterized in that a facultative anaerobic
`
`fermentation and an aerobic fermentation are carried out simultaneously.
`
`[0014]
`
`Further, the present invention relates to a garbage disposal apparatus according t
`
`o claim 3.
`
`A sensor for detecting the rotational position of the drum is provided.
`
`According to the present invention, there is provided a garbage disposal apparatu
`
`s in which the inlet is automatically stopped in a predetermined position.
`
`[0015]
`
`Further, the present invention relates to a garbage disposal apparatus according t
`

`
`To open the door of an inlet at the time of inputting garbage.
`
`The garbage disposal device has a mechanism in which the door and the outer pl
`
`ate are locked to prevent rotation of the drum.
`
`[0016]
`
`Further, the present invention relates to a garbage disposal apparatus according t
`
`o claim 5.
`
`A hot air generator for temperature control and drying inside the drum is provide
`
`d.
`
`A humidity sensor and a temperature sensor are provided inside the drum ;
`
`This garbage treating device is characterized in that a temperature and a humidit
`
`y are adjusted by an air volume and an air temperature of a hot air generator.
`
`[0017]
`
`Further, the present invention relates to a garbage disposal apparatus according t
`
`o claim 6.
`
`

`

`https://www.j-platpat.inpit.go.jp/p0200
`
`The outer plate of the casing is formed of a net-like material.
`
`It is a garbage disposal apparatus characterized by things.
`
`[0018]
`
`According to the present invention, it is possible to reduce the weight reduction ti
`
`me and reduce the amount of garbage in 1 days. In other words, a woody chip is
`
`put into a treatment tank to adjust a moisture content to obtain an optimum hum
`
`idity for fermentation, and the same woody chip is used as a bacterial bed materi
`
`al for holding a fermentation bacterium at the same time, and a hotair is introdu
`ced into a tank for securing a fermentation temperature and evaporation (drying)
`of water, thereby maintaining an optimum temperature condition for fermentatio
`n.
`
`[0019]
`
`In addition, 2 double agitation is performed, I. e., reverse stirring by a rotary dru
`
`m and flow agitation in an axial direction of a vane fixed on the inner surface of t
`
`he rotary drum, and a vane having a different direction of a stirring surface fixed
`
`on a fixed through central axis, so that the target is uniformly mixed.
`
`[0020]
`
`As a result, sufficient ventilation is made possible, and by simultaneously advanci
`
`ng the facultative anaerobic fermentation / aerobic fermentation, the reduction tr
`
`eatment of garbage is efficiently realized.
`[0021]
`Further, according to the present invention, the structure can be simplified. In ot
`her words, stirring power is reduced by using a stirring method using drum rotati
`
`on, and a stirring driving device is miniaturized.
`
`[0022]
`
`Conventionally, since a passage of a gas passing between an inside and an outsid
`
`e of a processing tank and a passage of a processing material have to be installed
`in a non-rotating portion, the side plate portion of the rotating drum is fixed and
`used for the purpose.
`
`[0023]
`
`In the present invention, the central penetrating fixing shaft has a hollow structur
`
`e so as to be used as a passage for introducing hot air and discharging steam. In
`
`addition, since continuous supply and discharge of garbage are not performed in
`
`a state in which the drum-side plate portion is always stopped, the drum portion
`
`and the side plate portion of the drum can be connected.
`
`[0024]
`
`As a result, the drum side plate portion can be rotated integrally with the body po
`
`

`

`https://www.j-platpat.inpit.go.jp/p0200
`
`rtion, and the airtight seal mechanism is reduced in size to about the diameter of
`
`the center shaft portion, rather than a large diameter portion. As a result, it is po
`
`ssible to use a commercially available seal member without requiring a specially d
`
`esigned hermetic seal.
`
`[0025]
`
`Since the central axis of penetration is fixed, the temperature inside the drum an
`
`d the humidity sensor are fixed along the central axis. As a result, there is no nee
`d for a rotation signal extraction device such as a brush or the like for signal extr
`action.
`
`[0026]
`Further, according to the present invention, it is possible to facilitate maintenance
`by simplifying the structure. In other words, by eliminating the supportroller of t
`
`he rotating drum, maintenance of the rotating portion becomes unnecessary. To r
`
`educe the frequency of replacement of a seal member by miniaturizing an airtight
`
`seal of a rotary drum. No maintenanceis required due to the absenceof a rotatin
`
`g signal extractor.
`
`[0027]
`
`Further, according to the present invention, it is possible to promote the aerobic f
`
`ermentation and consequently to suppress the generation of malodor, since it is s
`
`ufficiently stirred by the rotating drum.
`
`[0028]
`
`Furthermore, according to the present invention, by storing a movable portion su
`
`ch as a rotary drum, a rotary drive device, or a warm air blower inside a housing
`
`formed of a net-like material, it is possible to visually confirm a situation in which
`
`the drum rotates.
`
`[0029]
`
`Further, by opening the door of the input port, the door is locked to the outer plat
`
`e of the casing, so that it is possible to safely prevent the drum from rotating sud
`
`denly.
`
`[Effect of the Invention]
`
`[0030]
`
`To provide a safe refuse disposal device which is small in weight reduction proces
`
`sing time, small in size, low in cost, and not polluting an environment.

`As can be seen in FIGS. 3 and 4, each of the blade surfaces of the rotary stirring
`
`blade 19 is mounted perpendicularly to the plane of the drum 1 of the drum 1 an
`
`d at an angle to the axis of rotation of the drum 10. The inclination of the wing su
`
`rface is such that when the drum 1 rotates clockwise when viewed from the left si
`
`de of the drawing, the processing object inside the drum 1 is sent from the side p
`
`late portion 11 toward the side plate portion 12.
`
`[0043]
`
`As can be seen in FIG. 3 (a) and FIG. 4 (a) and FIG. 4 (b), a fixed stirring blade 2
`
`4 is installed perpendicularly to the through shaft 20 and in 4 directions from the
`
`center at right angles to each other, I. e., from the center of the *.
`
`ly. Also, the w
`
`ing surface is mounted at an angle with respect to the direction of the central axi
`Ss.
`
`[0044]
`
`When viewed from the left side of the drawing, the inclination of the blade surfac
`e is such that, when the drum 1 rotates clockwise and the processing target insid
`e the drum 1 reverses clockwise, it is fed from the side plate portion 12 toward th
`
`e side plate portion 11, contrary to the case of the rotary stirring blade 19.

`
`As also shown in FIG. 3, the through shaft 20 has a hollow structure, and an airs
`
`upply pipe 31 is inserted from one end (right side in the drawing) of the hollow st
`
`ructure. Inside the drum 1, the air supply pipe 31 rises at right angles from the t
`
`hrough shaft 20 and is inclined in the rotation direction of the drum by a fixed an
`
`gle in a rotation direction from a vertical direction, and a tip end portion thereofi
`
`s curved in a U-shape, and an air supply port 32 is opened in a high position insid
`
`e the drum 1.
`
`[0046]
`
`As shown in FIG. 4 (a), the other end of the air supply pipe 31 is connected to a
`
`hot air generator 55 installed outside the drum 1, and hot air can be introducedi
`
`nto the drum 1 as needed.
`
`[0047]
`
`Further, as shown in FIG. 3 (a), in the inside of the rotary drum, at a position clos
`
`e to the side plate portion 11, an exhaust pipe 33 rises perpendicularly from the t
`
`hrough shaft 20 in a posture similar to that of the air supply pipe 31, and a tip th
`
`ereof curves in a U-shape, and an exhaust port 34 opens downward.
`
`[0048]
`
`The other end of the exhaust pipe 33 opens into a hollow portion of the through s
`
`haft 20. As shown in FIG. 3 a, a partition plate 37 is provided at an intermediate
`
`portion of the hollow portion of the through shaft 20, and the exhaust gas flows t
`
`o the left side of the drawing and flows out to the external exhaust pipe 36 via th
`
`e exhaust outlet 35.
`
`[0049]
`
`If necessary, an odor absorbing / decomposing device may be connected to the o
`
`ther end of the external exhaust pipe 36.
`
`[0050]
`
`As shown in FIG. 2, a garbage inlet port 13 is formed in a drum portion 10 of the
`
`drum 1, and an inlet port 14 for closing the inlet port 13 is connected by a hinge.
`
`[0051]
`
`Whena rotation stop switch is pressed when a drum 1 is automatically operated
`
`by an automatic operation control circuit (not shown), a rotation position sensor
`
`(not shown) detects a rotation angle of a drum 1, and stops a motor 54 so that a
`
`charging port 13 in a drum 10 of a drum 1 is at the same position as an external
`
`charging port 44 of a housing 40.
`
`[0052]
`
`FIG. 6 is a partial cross-sectional view of the drum 1, the frame 41 of the housing
`
`40, and the outer plate 45 seen from the front side, and shows an openstate of t
`he inlet door 14. As shown in FIG. 6, when the inlet port 13 of the inlet port 44 is
`opened via the external inlet port 1 when the drum 14 stops, the inlet port door 1
`
`

`

`https://www.j-platpat.inpit.go.jp/p0200
`
`4 is locked to the external inlet port 44 formed on the outer plate 45 of the housi
`
`ng. As a result, the drum 1 and the outer plate 45 are integrated, so that the dru
`
`m 1 does not rotate in the drum 10.
`
`[0053]
`
`Accordingly, when the inlet door 14 is opened and garbage is supplied, the drum
`
`1 does not careiessly rotate.
`
`[0054]
`
`As shown in FIG. 2 and FIG. 3 and FIG. 4 (b), there is provided a discharge port
`
`door i6 for closing the discharge port 15 by forming a discharge port 15 for the r
`
`esidue of the residue of the processed material on the side plate portion 12 of the
`
`!
`_
`
`drum 10. When the inlet 13 stops at the position of the external inlet 44, the outl
`et 15 is at the lowest rotation position.
`[0055]
`As shown in FIG. 3, a temperature sensor and humidity sensor 61 is provided nea
`
`r the center of the surface of the through shaft 20. The signals of both sensors re
`
`ach the control panel 60 shown in FIG. 4 via a wiring 62 arranged along the hollo
`
`w portion of the through shaft 20. A signal which has reached an automatic contr
`| ol circuit (not shown) inside the control panel 60 is used to measure the humidity
`and temperature inside the drum 1.
`
`[0056]
`
`Specifically, the air volume and the hot air temperature of the hot air generator 5
`
`5 are controlled.
`
`[0057]
`
`A state in which the garbage disposal apparatus is operated will be described with
`
`reference to FIGS. 5 and 6. FIG. 5 is a conceptual diagram of a process situation
`
`of garbage in which only a necessary portion is drawn in addition to a cross sectio
`
`n of the drum 1 when viewed from the front of the dust disposal apparatus.
`
`[0058]
`
`First, an inlet door 14 of a drum 1 which is stopped is opened, and a humidity adj
`
`usting agent consisting of a wood chip is previously charged. Fermented bacteria
`
`are previously mixed with fermentation bacteria so as to be simultaneously used
`
`as a fermentation bacteria carrier.
`
`[0059]
`
`Since woodchips are hardly fermented and eliminated by fermentation bacteria, t
`hey can be used without replenishment for a long period of time.
`
`[0060]
`
`Next, a sprocket 24 is driven by a chain 51, and air of an appropriate amount and
`
`temperature is generated by a blower of a hot air generator 55 while rotating a dr
`
`

`

`https://www.j-platpat.inpit.go.jp/p0200
`
`um 1, is fed into an air supply pipe 31, and is introduced into a drum 1 through a
`
`n air supply port 32, so that the inside is brought into a humidity and temperatur
`
`e suitable for the activity of fermentation bacteria.
`
`[0061]
`
`Next, once the drum 1 is stopped, the garbage inlet door 14 is opened, and garba
`
`ge is charged. Since the door is locked to the outer plate 45 of the housing 40, th
`
`e drum 10 is not unexpectedly rotated due to some reason during the loading ope
`
`ration, so that the work can be safely performed.
`
`[0062]
`
`After the garbage is thrown into the drum 1, the inner wood chips and garbage ar
`
`e agitated and homogenized, and then the garbage is immediately fermented.
`
`The inside is maintained at the optimum humidity and temperature for the activit
`
`y of the fermenting bacteria, and the rotating drum is rotated and stopped appro
`
`priately, and aerobic fermentation and facultative anaerobic fermentation are sim
`
`ultaneously carried out.
`
`[0063]
`
`Intermittently, for example, rotates between 15 to 45%of a fixed time and stops
`
`between 55 to 85%. In this way, the fermentation proceeds in an optimum state,
`
`and electric power can be saved.
`
`[0064]
`
`By rotating the drum 1, the processing object 70 comprising garbage and wood c
`
`hips is lifted by the rotary stirring blade 24 in the rotation direction R indicated by
`
`the arrow shown in FIG. 5, and is reversely stirred. When the arrangementof the
`fixing stirring blade 24 and the direction of a surface area which were installed in
`the rotation stirring blade 19 and the penetration shaft 20 which wereinstalled in
`
`the rotating drum differ from each other, flow stirring is carried out in an axial dir
`
`ection at order.
`
`[0065]
`
`In this manner, sufficient air can be easily sent to garbage, and the aerobic ferme
`
`ntation can be easily progressed, and reduction in weight can be achieved in a sh
`
`ort time by fermentation treatment.
`
`[0066]
`
`When garbage is reversely stirred, fine garbage and wood chips are scattered int
`
`he drum 1, but the air supply port 32 and the exhaust port 34 which are located
`
`at the U-shaped tip of the air supply pipe 31 and the exhaust pipe 33 and open d
`
`ownward do not easily come into contact with each other and are not clogged.
`
`[0067]
`
`The torque for rotating the drum 1 is much smaller than the torque required to ro
`
`

`

`https://wwwj-platpat.inpit.go.jp/p0200
`
`tate the stirring blades in a fixed processing tank. Further, since it is only necessa
`
`ry to rotate intermittently, the power consumption can be reduced.
`
`[0068]
`
`As fermentation progresses, the easy fermentation component of garbage is finall
`
`y converted into steam and carbon dioxide by aerobic fermentation. The generate
`
`d steam and carbon dioxide gas are diffused from the external exhaust pipe 36 th
`
`rough the exhaust port 34 into the atmosphere through the exhaust pipe 33. The
`
`reby, loss in quantity proceeds.
`
`Further, moisture is reduced by being dried by the heat generated by the hotair
`
`generator, and the weight reduction proceeds.
`
`[0069]
`
`Since aerobic fermentation is active, no malodor is generated.
`
`[0070]
`
`Fermentation for approximately 1 days ends the treatment of the input garbage a
`
`nd almost no residue occurs. Therefore, it is possible to cope with a place where
`
`garbage regularly occurs everyday, such as a restaurant or a food supply cooking
`
`place, or a food sales sales room, which generates a large amount of garbage dail
`
`y.
`
`[0071]
`
`Normally, the processing object 70 in the drum is operated so as to occupy 50 to
`
`70%of the internal volume of the drum. Since the residue is not at all 0, the amo
`
`unt of the object to be processed 70 increases, but if it exceeds about 80%, ane
`
`xcess amountis discharged. Further, the humidity-adjusting agent and the ferme
`
`nting bacteria carrying material which have been changedin quality after being u
`
`sed for a long time are replaced. In such a case, when the rotation is stopped, th
`
`e drum 1 is automatically stopped so that the overflow port 17 is in a predetermi
`
`ned position, and thus the overflow door 18 is opened to scrape out the contents.
`
`[0072]
`
`The housing 40 hasa structure in which the frame 41 is covered with an outerpla
`
`te 45 made of a net-like material, and a person and an animal do not touch the
`
`movable equipment inside. Also, since the drum 1 is easily seen to be rotating, th
`
`e operating situation can be checked and secured at any time.
