Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposal device for decomposing food waste (garbage) generated in a kitchen by the activity of microorganisms such as cocci and bacilli.

[0002]

2. Description of the Related Art Kitchen wastes that are generated daily in kitchens such as general households and restaurants, if left unattended, cause bad odors due to rotting and breed pests, deteriorating the sanitary environment of the kitchen. It is necessary to process promptly and hygienically.

The conventional kitchen waste treatment is generally carried out by a method of capturing the kitchen waste that is thrown into the drainage basket installed at the drainage port of the sink together with the drainage, and taking it out appropriately and discarding it together with other garbage. . However, in this method, in order to prevent spoilage of the kitchen waste trapped in the drainage basket and to maintain a good sanitary environment in the kitchen, it is necessary to frequently remove and discard the captured kitchen waste, and each time of this removal. However, there is a problem in that secondary work, which is complicated, such as refilling the trapped kitchen waste with a plastic bag and washing the drain basket, is forced.

In Europe and America, a method is widely adopted in which a kitchen crusher (disposer) is connected to the drainage port of a sink to crush the kitchen waste and dispose of it in the public sewer together with the drainage. However, in Japan, where there are many sewage systems that combine with rainwater, the public sewer system may become eutrophied due to the fact that overflow of inflow water may cause pollution of natural waters such as rivers and lakes. Suspended solids (SS) and biochemical oxygen demand (BOD) in wastewater
However, wastewater from a disposer that contains crushed garbage and is in a thick liquid state cannot meet the above regulations, and this kind of garbage treatment is actually prohibited.

[0005] As one method of garbage disposal to solve the above-mentioned problems, there is a method of decomposing garbage by microorganisms, and a composter has been conventionally known as this kind of garbage disposal device. A composter is a tubular body with a lid plate on one side opening, and is used by embedding it in the soil for a suitable length with the other side facing downward.The lid plate is opened and kitchen waste is thrown inside, It is left in a closed state and the input kitchen waste is composted by the activity of microorganisms (soil fungi).

[0006] The garbage treatment performed in this manner does not require a secondary operation for the disposal of the garbage, and the garbage incinerator,
It is desirable from the viewpoint of environmental protection without the possibility of causing inconveniences such as an increase in treatment load at the sewage treatment plant and pollution of natural water areas. However, the use of the composter is premised on the existence of soil for embedding, and the composting of kitchen waste inside is extremely gradual, and there is a possibility that a strange odor generated during this period may leak to the surroundings. It is not practical to use the poster in an urban area with many apartments.

The applicant of the present application has already proposed a kitchen waste treating apparatus which can be used in urban areas by utilizing the decomposition of kitchen garbage by microorganisms. This is done by crushing the garbage that is thrown in from the garbage throwing port by the crushing means, introducing it into the processing tank connected to the discharge port of the crushing means, and mixing it with the processing medium stored inside the processing tank. This is a device having a simple configuration. The treatment medium is a wood strip such as sawdust, rice husk, rice bran, soil or the like microbial culture substrate, and inside the treatment tank containing this treatment medium, an environment suitable for breeding various microorganisms is provided. Has been maintained. Thus, the refuse fragments that are introduced into the treatment tank and mixed with the treatment medium are mixed with these by the microorganisms (cocci and bacilli) that propagate in the treatment medium and are mixed with water (H ₂ O) and carbon dioxide. It is decomposed into gas (CO ₂ ).

[0008] That is, in the case of using this garbage processing device, the user only needs to put the garbage generated every day into the garbage input port and send it to the crushing means, and the water generated as a result of the decomposition. Is discharged to the sewage through the drainage port that opens at the bottom of the treatment tank, and carbon dioxide gas is also released to the atmosphere, and the kitchen waste is completely extinguished. It is possible to significantly reduce the amount compared with that in the composter by selecting the above and optimizing the internal environment of the treatment tank, and from the viewpoint of environmental conservation, sanitary garbage treatment can be achieved with a small labor burden.

[0009]

In the garbage treating apparatus having the above-mentioned structure, the mixing means for mixing the processing medium and the garbage may be operated only when the garbage is charged. Since the crushing means for crushing the garbage also operates, it is rational to drive the mixing means and the crushing means by a common drive motor. In this drive, the drive shaft of the mixing means and the drive shaft of the crushing means are projected to one side of the processing tank, and a chain or a belt is provided between the output shaft of the drive motor and the both drive shafts arranged on the same side. It can be realized by a structure in which the winding transmission means such as the above are collectively wound and the driving force of the drive motor is transmitted to the mixing means and the crushing means.

However, when the simple transmission system as described above is constructed, the chain or belt, which is a common winding transmission means, frequently comes off, and a tension applying mechanism is provided in the middle of the winding transmission means. A transmission system having a more complicated structure than the above-described transmission system, such as a structure in which a separate winding transmission unit is wound between the drive motor and each of the crushing unit and the mixing unit, is adopted. The above-mentioned inconveniences are being solved.

The present invention has been made in view of the above circumstances, and has a complicated structure in which the winding transmission means, which is integrally wound between the mixing means and the crushing means and the common drive motor, is disengaged. It is an object of the present invention to provide a garbage disposal device which can be prevented by any means and can be stably driven by a simple transmission system.

[0012]

Means for Solving the Problems The kitchen waste processing apparatus according to the present invention comprises a crushing means for crushing garbage, a processing tank connected to an outlet of the crushing means for containing a processing medium, and an inside of the processing tank. And a crushing means, the crushing means and the crushing means are collectively wound around respective drive shafts projecting to one side of the processing tank, and are driven in common by a winding transmission means. Kitchen waste that is driven by a motor and is mixed into the processing medium by the operation of the mixing means, and the garbage that is introduced into the processing tank from the outlet of the crushing means is decomposed by the activity of microorganisms in the processing medium. In the device, the drive motor and the crushing means are arranged above the drive shaft of the mixing means, and the transmission of the driving force of the drive motor by the wrapping transmission means from the crushing means to the crushing means. Order to mixing means Carried thereby, characterized in that are.

[0013]

In the present invention, the disengagement of the winding transmission means such as a chain or belt wound between the drive motor and the crushing means and the mixing means is caused by the looseness of the winding transmission means between them. This slack is concentrated in the portion from the drive motor to the crushing means or the mixing means, not in the portion from the crushing means or the mixing means to the drive motor. Focusing on the upper position, the drive motor is arranged above the mixing means, so that the winding mode of the winding transmission means is such that the winding position on the mixing means is a downward vertex in plan view. While exhibiting a triangle shape, the transmission by the winding transmission means is performed in order from the crushing means to the mixing means. As a result, the looseness of the winding transmission means is concentrated between the drive motor and the crushing means, that is, on the upper side of the triangle, and this slackness results in an increase in the winding length around the drive motor and the crushing means. It acts to prevent disengagement.

The treatment medium A is a culture substrate that forms an environment suitable for the propagation of various microorganisms (fungi), and is disclosed, for example, in Japanese Patent Publication No. 34679/1990, "Method for treating sludge with microorganisms from wood." As described above, it is sufficient to use a wood strip made porous by a predetermined treatment. At the center of the bottom surface of the treatment tank 2, a drain port 20 is opened so as to face the water receiving pan 11 fixed to the outer lower portion of the outer box 1. In addition, in order to prevent the processing medium A from falling off, a fine mesh plate such as punching metal is stretched over the drainage port 20.

A stirring shaft 40 is rotatably supported at a position slightly above the center of the inside of the processing tank 2 so as to be rotatable about a substantially horizontal shaft center. A plurality of stirring blades 4, 4 ... Are provided so as to be spaced at appropriate intervals. These stirring blades 4, 4 ... Rotate according to the rotation of the stirring shaft 40 to stir the processing medium A inside the processing tank 2 and function as a mixing means for mixing with the kitchen waste introduced as described later.

On the other hand, at the upper part of the outer box 1, the kitchen waste inlet 10
A crusher 3 for crushing the garbage thrown from is installed. The crusher 3 includes a transfer pipe 30 which is horizontally laid across the inside of the processing tank 2 and a transfer screw 31 which is rotatably supported inside the transfer pipe 30 about an axis. Prepare,
The receiving port, which is continuously provided upward at the base end of the transfer pipe 30, is connected to the kitchen throwing port 10 that opens at the upper part of the outer box 1. Note that the kitchen waste inlet 10 is covered with a lid plate 12 that can be opened and closed, and a pusher 13 is provided at the inlet of the transfer pipe 30.
Is detachably fitted, and the receiving port is opened by removing the pusher 13.

FIG. 3 is an enlarged cross-sectional view of the vicinity of the tip of the crusher 3. As shown in the figure, a fixed blade 32 having a plurality of blades extending radially from the center is fitted to the tip of the transfer tube 30. A discharge port 33 that is fixed and faces the inside of the processing tank 2 is configured,
A rotary blade 34, which rotates while slidingly contacting the fixed blade 32 as the transport screw 31 rotates, is attached to the tip of the transport screw 31 that faces the discharge port 33. This structure is known, for example, in a meat grinder used for making minced meat.

The transfer screw 31 of the crusher 3 and the agitation shaft 40, which serves as the rotating shaft of the mixing means, penetrates the side wall of the processing tank 2 and projects to the outside on the same side. 3a and 4a are fitted and fixed, respectively. On the other hand, a motor box 51 is provided in the upper part of the inside of the processing tank 2 at a position different from the disposing position of the crusher 3, and the drive motor 5 is housed inside the motor box 51 as shown in FIG. Has been done. The output shaft of the drive motor 5 is projected on the same side as the transfer screw 31 and the stirring shaft 41, and the drive sprocket 5a is fitted and fixed to the projecting end.

The drive motor 5 serves as a drive source for the crusher 3 as the crushing means and the stirring blades 4, 4, ... As the mixing means, and the transmission from the drive motor 5 to the both means is performed by the drive motor 5. The drive sprocket 5a at the output end, and the separate sprocket 3a at the protruding end of the transfer screw 31 and the stirring shaft 40 and
It is performed via a drive chain 50 that is wound around the 4a and the 4a all together.

FIG. 4 is a view taken along the line IV-IV in FIG. 2 and shows the manner of winding the drive chain 50. Since the crusher 3, the stirring shaft 40, and the drive motor 5 are arranged as described above, the drive sprocket 5a of the drive motor 5 and the sprocket 3a of the crusher 3 are agitating shafts of the mixing means as shown in the drawing. The drive chain 50, which is positioned above and below the sprocket 4a of the shaft 40 with a proper distance left and right and is wound around the sprockets 3a, 4a, and 5a collectively,
The sprocket 4a, that is, a triangle having a winding position on the mixing means as a downward vertex is formed.

A drive chain wound as described above
The 50 circulates along the above-mentioned winding path according to the rotation of the drive motor 5, and as shown by the arrow in FIG. 4, this circulation starts from the drive sprocket 5a and then goes to the sprocket 3a. Then, the sprocket 4a and the drive sprocket 5a are sequentially returned to the drive sprocket 5a. That is, the transmission of the driving force of the drive motor 5 by the drive chain 50 is first performed to the transfer screw 31 (crushing means) on one side of the drive motor 5, and then the stirring shaft 40 positioned below them. (Mixing means).

As described above, in the device according to the present invention, the transmission to the transfer screw 31 and the stirring shaft 40 are the sprockets respectively.
It is configured to be carried out via a drive chain 50 that is wound around 3a and 4a all together, and during this transmission, it is inevitable that the drive chain 50 will loosen, and this looseness is the drive source. Concentrate on the exit side from the drive motor 5. However, in the device of the present invention having the above-mentioned arrangement and setting of the transmission direction, the above-mentioned slack of the drive chain 50 is caused by the portion from the drive motor 5 toward the transfer screw 31.
That is, the loosening that occurs in the laterally stretched portion increases the winding length of the drive sprocket 5a and the sprocket 3a as shown in FIG. 4, and the risk of the drive chain 50 coming off is extremely high. Low.

On the other hand, when the transmission is performed in the direction opposite to the above-mentioned direction, the looseness of the drive chain 50 is as shown by the chain double-dashed line in FIG. This loosening occurs in the vertical stretched portion between the motor 5 and the agitation shaft 40, and this slack reduces the winding length of the drive sprocket 5a and the sprocket 4a, which may cause the drive chain 50 to come off. high.

That is, in the device of the present invention, the transmission from the drive motor 5 to the transfer screw 31 of the crusher 3 and the stirring shaft 40, which is the rotating shaft of the mixing means, is carried out by the drive chain 50 which is wound around them collectively. In the structure for transmission, the drive motor 5 is arranged above the stirring shaft 40, and the direction of transmission by the drive chain 50 is changed from the transfer screw 31 to the stirring shaft.
By performing the steps in the order of 40, stable transmission is achieved without causing the drive chain 50 to come off.

In the operation of the apparatus of the present invention constructed as described above, first, the cover plate 12 which covers the upper part of the garbage throwing port 10 is opened, and the pusher 13 is removed to open the receiving port of the crusher 3. The procedure is as follows: throw the kitchen waste into the kitchen throwing port 10, push the kitchen waste into the transfer pipe 30 with the pusher 13, turn on the operation switch (not shown), and rotate the drive motor 5.

As described above, the driving force of the drive motor 5 is stably transmitted to the transfer screw 31 of the crusher 3 and the agitation shaft 40 inside the processing tank 2.
40 rotates. Then, the garbage pushed into the transfer tube 30 as described above is transferred toward the tip of the transfer tube 30 by the rotation of the transfer screw 31, and inside the processing tank 2, the stirring blades 4, 4 ... Thus, the processing medium A is agitated.

The rotary blade 34 attached to the tip of the transfer screw 31 also rotates as the transfer screw 31 rotates, and the garbage reaching the tip of the transfer tube 30 is fixed to the rotary blade 34 and the fixed blade slidably contacting the rotary blade 34.
The particles 32 are finely crushed by 32 and are introduced into the processing tank 2 through the discharge port 33 at the tip of the transfer pipe 30, and the stirring blades 4, 4
Is mixed with the processing medium A that is being stirred by and dispersed in the processing tank 2.

The operation of the device according to the present invention as described above is completed after the rotation of the drive motor 5 is continued for a while in accordance with the operation of turning off the operation switch by the user who has finished throwing the garbage into the garbage inlet 10. After that, the device of the present invention keeps the standstill and stands by until the next throwing of the garbage. The above-described continuation of the rotation of the drive motor 5 is necessary in the crusher 3 in order to reliably discharge the garbage thrown from the garbage throwing port 10 without remaining inside the transfer pipe 30. Tank 2
Is necessary in order to sufficiently mix the kitchen waste with the processing medium A by rotating the stirring blades 4, 4.

As described above, the treatment medium A in the treatment tank 2 is a microbial culture base material that forms an environment suitable for the growth of microorganisms, and is a waste of the kitchen waste that is introduced into the treatment tank 2 and mixed with the treatment medium A. The fragments are various microorganisms (cocci and bacilli) brought in with the kitchen waste during the standby after the operation is stopped,
And is decomposed by the activity of microorganisms already propagated in the treatment medium A.

Decomposition of kitchen waste in the treatment medium A is a process in which kitchen waste is decomposed by the action of microorganisms in an anaerobic environment, and kitchen spoilage decomposed by the activity of microorganisms in an aerobic environment is treated with water ( The process of decomposing into H ₂ O) and carbon dioxide gas (CO ₂ ) is repeated. The water generated thereby passes through the layer of the treatment medium A, reaches the bottom of the treatment layer 2, flows out to the water receiving pan 11 through the drain port 20, and is further connected to the water receiving pan 11. After being discharged to the sewer through the drainage pipe, the carbon dioxide gas generated in the same way is exhausted to the surroundings, and the treatment tank 2
The kitchen garbage inside disappears completely. Since the carbon dioxide gas has an offensive odor in the spoilage process of garbage, when the device of the present invention is used indoors, it is desirable to provide an exhaust means for releasing the carbon dioxide gas to the outside air.

In this embodiment, the case in which the drive chain 50 is used as the winding transmission means that is collectively wound around the drive shafts of the crushing means and the mixing means has been described.
It is needless to say that the present invention can be applied to the case where a transmission system using a belt such as a V-belt or a flat belt is provided, and similar effects can be obtained.

[0034]

As described in detail above, the apparatus of the present invention is provided with a crushing means for crushing kitchen waste and a mixing means for mixing the kitchen waste introduced into the processing tank with the processing medium, collectively on these drive shafts. In a configuration in which a common drive motor is driven via a wound winding transmission means, the drive motor is arranged above the mixing means, and the transmission by the winding transmission means is performed in order from the crushing means to the mixing means. Since the looseness of the winding transmission means is concentrated between the drive motor and the crushing means, and the looseness increases the winding length of the winding transmission means, the disengagement of the winding transmission means is complicated in structure. The present invention has excellent effects, such as preventing the change regardless of the change and enabling stable driving with a simple transmission system.
