DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings showing the embodiments. FIG. 1 and FIG. 2 are side sectional views showing an embodiment of the garbage processing apparatus according to the present invention (hereinafter referred to as the apparatus of the present invention).

As shown in the figure, the apparatus of the present invention comprises a processing tank 1 having a processing medium 2 housed therein in an outer box 3 having a rectangular box shape. The processing tank 1 is a hollow container configured to have a barrel shape as a whole as shown in the drawing, with both sides in the axial direction reduced in diameter toward the respective ends, and one side of the processing tank 1 is An end portion of the reduced diameter portion on the same side is opened over the entire surface, and a garbage feeding port 10 is formed.

The apparatus of the present invention is characterized in that the processing tank 1 is made of a combustible material, as will be described later in detail. Further, the treatment medium 2 is a wood strip which is made porous by a predetermined treatment to ensure good air permeability and water retention,
It is housed inside the processing tank 1 to an extent of occupying approximately half the depth thereof.

An opening 30 is formed in the upper part of the outer case 3 with a corner on one side (front side) as the center and a notch extending to almost the center of both sides sandwiching the corner. Yes, the opening 30 is
It is openably and closably covered by a lid plate 31 that is hinged along one edge of the notched edge on the upper surface side. Note that FIG.
Shows the closed state of the cover plate 31, and FIG. 2 shows the opened state of the cover plate 31, respectively.

A support leg 32 is erected on the bottom surface inside the outer case 3 near the corner on the back side, and the tip of the support leg 32 is provided around an axis inclined at a predetermined angle with respect to the bottom surface. A bearing 33 is rotatably mounted, and the holding body 4 is pivotally supported on the bearing 33. As is apparent from FIG. 2, the holding body 4 has a cup-like shape substantially corresponding to the bottom half of the processing tank 1, and the center of the bottom portion is the bearing 33.
The outer side opening faces the opening 30 of the outer casing 3.

Further, on the bottom surface inside the outer casing 3, a stirring motor 5 is fixedly provided near the corners on the front side, and the output shaft of the stirring motor 5 protruding toward the rear side of the outer casing 3. A cone-shaped drive roller 50 is fitted to the tip of the drive roller.
The reference numeral 50 is rolled from below to the outer peripheral surface of the holding body 4 in the vicinity of the opening.

The processing tank 1 has a cover plate 31 as shown in FIG.
1 is introduced into the outer box 3 through the opening 30 with the bottom open, and by fitting the bottom half portion thereof to the inside of the holding body 4, as shown in FIG. 10 is held so as to face the opening 30.
The holding body 4 is rotatably supported by the bearing 33 so as to be rotatable about an inclined axis, and the holding body 4 is driven by the weight of the holding tank 4 and the processing tank 1 to be brought into contact with the outer peripheral surface on the other side.
Since it is pressed against 50, when the stirring motor 5 is driven in the state shown in FIG. 1, the processing tank 1 rotates around the tilt axis together with the holder 4 that holds the stirring tank 5.

The cover plate 31 for covering the opening 30 of the outer case 3 is provided with an inclined portion which faces the kitchen waste inlet 10 of the processing tank 1 in the closed state as shown in FIG. Is
An air intake hole 34 is formed so as to penetrate the inside and outside, and a drying means 6 is attached to the inside of the air intake hole 34 so as to face the inside of the processing tank 1 through the garbage inlet 10.

The drying means 6 comprises an intake fan 60 and a heater 61. The intake fan 60 is driven to rotate to suck the outside air from the intake hole 34, and the outside air is energized to the heater 61 which is in a heat generating state. It is configured such that they are brought into contact with each other, heated, and introduced into the processing tank 1. After being circulated in the processing tank 1, the introduced outside air flows into the outer box 3 through the garbage introduction port 10 and is discharged to the outside through an exhaust hole 35 formed through the back wall of the outer case 3. To be done. A deodorizing filter 36 is attached to the inside of the exhaust hole 35, and the exhaust air from the exhaust hole 35 is generated through deodorization by the deodorizing filter 36.

The apparatus of the present invention constructed as described above opens the lid plate 31 on the upper part of the outer box 3 and feeds the garbage A onto the processing medium 2 in the processing tank 1 through the garbage feeding port 10 which opens obliquely upward. It is used in the procedure of closing the lid plate 31 after turning on, and turning on an operation switch (not shown). When this operation is performed, the stirring motor 5 is driven for a predetermined time, and the operation of the drying means 6, that is, the driving of the intake fan 60 and the heater 61.
Is energized for a predetermined time.

By driving the stirring motor 5, the drive roller 50 at the output end rotates, and the processing tank 1 rotates together with the holding body 4 whose outer peripheral surface is pressed against the drive roller 50. This rotation occurs around the tilt axis as described above, but at this time, the processing medium 2 inside the processing tank 1 tries to keep its upper surface horizontal, so that not only in the circumferential direction of the processing tank 1 but also in the axial direction. It is stirred as it moves. Therefore, the garbage A introduced as described above is mixed while being taken into the processing medium 2, and is dispersed inside the processing medium 2 on average as shown in FIG.

During this period, the intake fan 60 of the drying means 6 is driven, and the heater 61 is energized to generate heat, so that warmed outside air is introduced into the processing tank 1 and the stirring motor 5 operates. The mixing of the processing medium 2 and the garbage A is performed while taking in warmed outside air.

The apparatus of the present invention, after finishing the above-mentioned operation of throwing in the garbage, performs a standby operation until the next time of throwing in the garbage, and the garbage A mixed in the processing medium 2 is decomposed during this period. It The treatment medium 2 is, as described above, a porous wood piece and has an environment suitable for the inhabitation of microorganisms. The kitchen waste A is brought into the treatment medium 2 together with the microorganisms and inhabits in the treatment medium 2. By the activity, it is decomposed into water (H ₂ O) and carbon dioxide (CO ₂ ) which are final products.

The activity of microorganisms in the treatment medium 2 can be enhanced by supplying an appropriate amount of water and air and maintaining an appropriate temperature. In the standby operation, for example, the stirring motor 5 and the drying means 6 are operated for a short time every predetermined time,
As a result, the processing medium 2 inside the processing tank 1 is dried by the drying means 6
By this operation, the warmed outside air is taken in and agitated, so that an appropriate amount of air is replenished and an appropriate temperature is maintained.

On the other hand, the treatment medium 2 is excellent in water retention, as described above, and appropriately takes in water produced by the decomposition of the garbage A and automatically adjusts the water content of itself. In the standby operation, excess water is discharged by stirring the processing medium 2 and evaporated by contact with warmed outside air introduced into the processing tank 1 to assist automatic adjustment of the amount of water in the processing medium 2. It is also necessary. In addition, the water vapor generated by the evaporation, together with the carbon dioxide gas generated by the decomposition of the garbage A,
It flows out into the outer box 3 together with the air circulating in the processing tank 1, and is discharged to the outside air through the exhaust hole 35. The carbon dioxide gas generated by the decomposition of the garbage A and the water vapor generated by the evaporation of the generated water contain a slight odor, and this odor is transferred to the outside air by the deodorizing filter 36 placed in front of the exhaust hole 35. Removed prior to release.

As described above, the apparatus of the present invention repeats the operation at the time of throwing the garbage and the operation in the standby state to process the garbage A which is thrown into the processing tank 1 every day. When hardly decomposable substances such as vinyl and shells are put into the processing tank 1 and a large amount of these are mixed in the processing medium 2, the processing medium 2 needs to be replaced.

As shown in FIG. 2, this exchange is carried out by opening the lid plate 31 on the upper part of the outer box 3, pulling out the processing bath 1 to the outside through the opening 30, and replacing it with a new processing bath 1. . As described above, the processing tank 1 is only supported with the bottom portion of the processing tank 1 being fitted into the holder 4 inside the outer box 3.
Since the opening 30 has a size larger than that of the processing tank 1, the old processing tank 1 for replacing the processing medium 2 and the new processing tank 1 are attached from the opening 30 side. it can.

However, during the normal operation for garbage treatment, the treatment medium 2 contains an appropriate amount of water, and also contains the garbage A and the difficult-to-decompose substance being treated, and has a considerable weight. It is difficult to pull out the processing bath 1 in this state.

In the apparatus of the present invention, before the processing tank 1 is replaced, the drying operation is performed according to the ON operation of the drying switch (not shown). In this drying operation, the driving of the intake fan 60 in the drying means 6 and the energization of the heater 61 are continuously performed, and the outside air sucked into the intake fan 60 is heated by the heater 61, so that the inside of the processing tank 1 is continuously supplied. To send to. As a result, the inside of the processing tank 1 is heated above the appropriate temperature during normal operation, the water contained in the processing medium 2 and the kitchen waste A mixed therein evaporates, and the hot air circulating in the processing tank 1 is discharged to the outside. Since it flows out into the box 3 and is continuously discharged to the outside air through the exhaust hole 35, the processing medium 2 and the kitchen waste A, and the processing tank 1 for storing them are gradually lost by retaining water and dried. To be

70% of the total weight of the processing medium 2 during normal operation
It retains water around it, and kitchen waste A in the processing medium 2
Owns around 80% of its total weight. The above-described drying operation is performed in order to appropriately remove the retained water to reduce the weight of the processing tank 1 and facilitate the withdrawal from the outer box 3. For example, in a condition where 6 kg of untreated or treated garbage A is mixed in 20 kg of the treatment medium 2,
When 80% of the water content of the processing medium 2 and the garbage A is removed by the drying operation described above, the weights of the processing medium 2 and the garbage A after the drying operation are 8.8 kg and 2.2 kg, respectively. The total weight of the processing tank 1 can be suppressed to a level of less than 20 kg, and the processing tank 1 can be easily pulled out for replacing the processing medium 2.

Whether or not the processing tank 1 needs to be replaced is because the volume of the processing medium 2 increases due to the accumulation of hardly decomposable substances.
It can be determined by observing the bulk of the processing medium 2 every time when the garbage A is thrown in every day.

FIG. 3 is a side sectional view showing an example of the replacement processing tank 1. As shown in the figure, the processing tank 1 accommodates an appropriate amount of the processing medium 2 therein, and a kitchen waste inlet 10 that opens to one side.
Is sealed with a sealing plate 11, and is preferably supplied in a state where the whole is housed in an outer bag 12, as indicated by a chain double-dashed line in the figure.

The illustrated processing tank 1 is a barrel-shaped outer case.
A waterproof sheet 14 is attached to the entire inner surface of 13 and the waterproof sheet 14
It has a three-layer structure in which a non-slip sheet 15 is attached to the inside of the cylindrical portion of the. The outer case 13 is made of a combustible material having rigidity enough to support the processing medium 2 housed therein, for example, rigid cardboard, wood, or combustible resin. The inner waterproof sheet 14 has a function of protecting the outer case 13 from moisture generated in the processing medium 2 at the time of use, and is made of a combustible material excellent in waterproof property, for example, a combustible resin sheet. I wish I had it. The waterproof sheet 14 can be omitted when the outer case 13 is made of the same material, that is, combustible resin.

Furthermore, the innermost anti-slip sheet 15 suppresses relative slippage of the processing medium 2 inside the processing tank 1 when the processing tank 1 is rotated together with the holder 4, and the processing medium 2 due to the rotation of the processing tank 1 is rotated. Is effectively stirred and absorbs excess water generated by decomposition of the garbage A to adjust the water content of the treatment medium 2, and has a rough surface and excellent water absorption. Combustible materials such as various kinds of cloth are used.

As described above, in the present invention, the processing medium 2
The processing tank 1 for storing the
Is dried together with the processing medium 2 and the garbage A inside by the above-described drying operation at the time of replacement. Therefore, the processing tank 1 pulled out from the outer box 3 for replacement
Can be incinerated as it is along with the processing medium 2 and the kitchen waste A inside, and can be stored in an appropriate bag such as the outer bag 12 in which the processing tank 1 for replacement is stored and is flammable. The waste can be collected as garbage, and the user can easily dispose of the treatment tank 1 after replacement.

FIG. 4 is a side sectional view showing another embodiment of the device of the present invention, and FIG. 5 is a transverse sectional view taken along the line VV of FIG. In the present embodiment, the bearing 33 that pivotally supports the holding body 4 is mounted on a support base 37 that is obliquely installed on the bottom of the outer casing 3 on the rear surface side, so that the support rigidity of the holding body 4 is enhanced. .

The stirring motor 5 is fixed to a lower part of a support base 51 which is obliquely installed on the upper rear side of the outer case 3.
As shown in FIG. 5, the stirring motor 5 is fixed to the lower part of the support base 51 at a position deviated to one side from the axis of the holder 4, and a driven roller 53 is pivotally supported at a position deviated to the other side. Yes, the driven roller 53 and the drive roller fitted to the output end of the stirring motor 5.
A transmission belt 54, which is wound around the outer circumference of the holding body 4 located at the lower part, is stretched between 52 and 52.

That is, in this structure, the holding body 4 is suspended from the upper portion by the transmission belt 54 stretched between the holding roller 4 and the driving roller 52 and the driven roller 53, and the transmission belt 54 is suspended. According to the rotation of the agitating motor 5 transmitted through the shaft, the agitating motor 5 rotates about the tilt axis. As shown in the figure, the transmission belt 54 is wound around substantially half the circumference of the holding body 4, so that the holding body 4 is supported in both up and down and left and right directions, and the stirring motor 5 rotates. Since the force is satisfactorily transmitted to the holding body 4, the rotation of the holding body 4 and the processing tank 1 held by the holding body 4 is stably generated, and the stirring of the processing medium 2 inside the processing tank 1 can be performed more reliably. Become.

As shown in FIG. 5, a pair of guide rollers 55 and 56 are pivotally supported on the support base 51 between the drive roller 52 and the driven roller 53. These rotate the outer peripheral surface of the holder 4 from the upper side and guide the rotation of the holder 4 to further stabilize the rotation of the processing tank 1 for stirring the processing medium 2.

In the above description, the drying means 6 is continuously operated during the drying operation, but it may be intermittently operated at predetermined intervals. However, in order to remove the water content of the processing tank 1, the processing medium 2, and the garbage A to the above-mentioned level, it takes about one day even for continuous operation, and the time required for intermittent operation is further increased. There is a problem of increasing. In addition, by performing the dry operation around one day at night, it is possible to do so without disturbing the daily input of the kitchen waste A.

In the above description, the drying operation is performed only by the operation of the drying means 6, but in addition to this, the stirring motor 5 is driven to mix the processing medium 2 at an appropriate timing. As a result, the time required for drying can be shortened.

[0044]

As described above in detail, in the apparatus of the present invention, since the processing tank for containing the processing medium is made of a combustible material, when the processing tank is replaced for exchanging the processing medium,
The processing tank can be incinerated together with the processing medium inside, and the user can easily perform the steps up to the disposal of the processing tank, which is necessary when exchanging the processing medium.

Further, since a drying means for heating the inside of the processing tank and drying it together with the processing medium and the kitchen waste inside is provided, when the processing tank is replaced, the processing medium and the kitchen waste inside the processing tank are removed by the operation of the drying means. By drying and reducing the weight, it is easy to remove the treatment tank and incinerate it thereafter.

Further, since the processing tank is held by the holding body which rotates about the tilt axis, the processing tank can be easily replaced by attaching and detaching the holding body to the inside, and the rotation of the processing tank which occurs together with the holding body causes the inside of the processing tank to rotate. The treatment medium is agitated while moving in the circumferential direction and the axial direction, the kitchen waste is mixed well into the treatment medium, and the drying by the operation of the drying means is effectively performed. The present invention has excellent effects such as shortening the required time.
