[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 with microorganisms.

[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.

In the conventional kitchen waste disposal, generally, a drainage basket is installed at the drainage port of the sink, and the kitchen waste that is thrown in with the drainage is captured in this drainage basket, and is appropriately taken out and disposed of together with other refuse. Is done by. In Western countries, a kitchen waste crusher (disposer) is installed at the drainage port of the sink, and the kitchen waste that is thrown into the drainage port is crushed by the operation of this disposer. The garbage treatment method is widely adopted.

However, in the former method, when the kitchen waste trapped in the drainage basket is taken out, the bad odor generated by the rotten kitchen waste floats in the kitchen, and inconveniences such as spillage of sewage in the sink of the sink occur. In order to maintain a good sanitary environment in the kitchen, there is a problem that a large amount of labor is required, such as frequently taking out and discarding the kitchen waste and washing the draining basket each time the kitchen is taken out.

On the other hand, the latter method is effective in maintaining a hygienic environment because the garbage is treated without staying, but the crushed kitchen waste is discarded into the sewage together with the drainage, so the sewer pipe This causes secondary inconveniences such as the blockage of the plant and the increase of the treatment load at the sewage treatment plant. Especially in Japan, where there are many combined sewer systems with rainwater, the public sewer system may be eutrophied due to the fact that overflow of inflow water may cause pollution of natural waters such as rivers and lakes. The amount of suspended solids (SS) and biochemical oxygen demand (BOD) in waste water to wastewater is strictly regulated, and wastewater from a disposer that contains crushed kitchen waste and is in a thick liquid state can meet the above regulations. In fact, disposer disposal is prohibited.

Further, in Japanese Patent Laid-Open No. 4-156959, the kitchen waste thrown into the drainage port of the sink is drained while being transferred by a screw, and collected in the kitchen bag attached to the discharge port at the end of the transfer route. Disclosed is a garbage disposal device configured to automatically seal a bag mouth when a predetermined amount of collection is reached. However, even when this garbage processing device is used, it is troublesome to take out and put in the garbage bag, and there is a risk that the garbage will remain in the middle of the transfer path and rot, and the transfer path, in particular, the discharge port. There is a problem that you have to clean the neighborhood frequently.

The applicant of the present application has already proposed a kitchen waste processing apparatus capable of solving the above-mentioned problems of kitchen waste processing. This is an apparatus having a simple structure in which the garbage thrown into the garbage throwing port is crushed by the crushing means, introduced into the processing tank, and mixed with the processing medium contained in the processing tank. The processing medium is wood chips such as sawdust, chaff,
It is a substrate for culturing microorganisms such as rice bran and soil, and an environment suitable for breeding various microorganisms (fungi) is formed inside the treatment tank containing this treatment medium. Thus, the garbage fragments introduced into the treatment tank and mixed with the treatment medium are mixed with these by the microorganisms introduced and propagated in the treatment medium to cause water (H ₂ O) and carbon dioxide (CO ₂ ). And decomposed into.

[0008] That is, in the case of using this garbage processing device, the user only needs to perform a simple operation of throwing the garbage into the garbage input port and feeding it to the crushing means connected to the input port. By disposing of the water generated as a result of the decomposition in the drainage pipe and also discharging carbon dioxide gas, the kitchen waste can be completely extinguished, and sanitary kitchen processing can be realized with a slight labor burden.

[0009]

In the kitchen waste treatment apparatus proposed above, a transfer pipe serving as a kitchen passage is installed between the kitchen waste inlet and the processing tank, and the shaft center is provided inside the transfer tube. While arranging a spiral body (transfer screw) which rotates around, a fixed blade provided with a plurality of blades that radially divide the opening is fixed to the discharge port at the tip of the transfer pipe opened inside the processing tank, and further.

Since the garbage is decomposed by the activity of the microorganisms inside the treatment tank, the treatment capacity mainly depends on the internal volume of the treatment tank, which is the area of activity of the microorganisms, but when the treatment tank is arranged below the sink, There is a limit to the internal volume of the processing tank.
Therefore, it is required to increase the treatment capacity as much as possible under the limited inner volume of the treatment tank. For this purpose, the garbage fragments introduced into the treatment tank through the crushing means are reduced in size. That is, more specifically, it is effective to increase the surface area of the fragments.

In the conventional crushing means, since the garbage fragments cut at the sliding contact portion between the rotary blade and the fixed blade are introduced into the processing tank from between the radial fixed blades as described above, It is conceivable to use fixed blades with multiple blades in order to obtain small debris. However, in such a case, the garbage cut by the rotary blade and the fixed blade cannot be removed from between the blades of the fixed blade and is clogged at the tip of the transfer pipe, and the garbage that is subsequently fed into the processing tank is introduced. May be obstructed and forced to frequently disassemble and inspect the crushing means.

The present invention has been made in view of the above circumstances, and the kitchen waste introduced into the processing tank can be made small without clogging of the transfer pipe, and the surface area of the kitchen waste can be made large. It is an object of the present invention to provide a garbage processing device capable of improving the processing capacity under the internal volume of a processing tank.

It is smaller at the fixed blade 33b on the tip side.

In the operation of the apparatus of the present invention constructed as described above, the pusher 25 is pulled out at the stage when an appropriate amount of garbage is trapped in the draining basket 21 as described above, and the draining basket 24 is opened in the draining basket 24 thus opened. This is carried out by introducing the kitchen waste in 21 and turning on an operation switch (not shown) to drive the crushing motor 31 and the mixing motor 43.

The kitchen waste introduced into the kitchen throwing port 24 is introduced into the transfer pipe 30 of the crusher 3, and is transferred toward the tip of the transfer pipe 30 by the rotation of the transfer screw 32 driven by the crushing motor 31. . At this time, the pusher 25 is used to push down the kitchen waste introduced into the kitchen throwing-in port 24 downward to assist the transfer to the transfer screw 32.

The kitchen waste transferred by the transfer screw 32 first reaches the sliding contact portion between the inner rotary blade 34a and the fixed blade 33a and is crushed by the action of both. At this time, since the fixed blade 33a has a small number of blade portions A, A ... And has a large opening between the blade portions A, A .. After passing through 33a, it reaches the sliding contact position between the rotary blade 34b on the tip side and the fixed blade 33b.
Similarly, the garbage is also crushed by the rotary blade 34b and the fixed blade 33b on the tip side, but the fixed blade 33b has a large number of blade portions A, A ... Since the opening is small, the kitchen waste is crushed until it becomes a sufficiently small fragment and is discharged from the tip of the transfer pipe 30 into the processing tank 4.

Thereafter, the apparatus of the present invention is kept in a stopped state until the next introduction of the garbage A, and during that time, the garbage A is decomposed. As described above, the processing medium B stored in the processing tank 4 is a microbial culture substrate that forms an environment suitable for the growth of microorganisms, and the kitchen waste A mixed with this processing medium B
The debris of 1 is decomposed by various microorganisms (fungi) possessed by itself and microorganisms already propagated in the treatment medium B.

This decomposition is due to the process of spoiling garbage by the activity of microorganisms in an anaerobic environment, and the activity of microorganisms in an aerobic environment to decompose the garbage in water (H ₂ O).
And a process of decomposing into carbon dioxide gas (CO ₂ ) are repeated. The aerobic environment is realized by the air in the upper space of the processing tank 4 being taken into the processing medium B by the rotation of the stirring rod 41 performed each time when the garbage is introduced, and the anaerobic environment is
It is gradually realized after the transition to the standby state. The water generated by this decomposition passes through the net plate 45 at the bottom of the treatment tank 4, accumulates in the water receiving pan 46, and is discharged to the sewage by the above-described operation of the drainage pump P. Since the mesh plate 45 is regularly cleaned by sliding contact with the brush 47 that occurs each time the stirring shaft 40 rotates, the generated water can pass through the mesh plate 45 without resistance, and the bottom portion of the processing tank 4 can be treated. Never stays in.

That is, in the treatment medium B in the treatment tank 4, by continuously feeding the garbage, the activity of the microorganisms in the anaerobic environment and the activity of the microorganisms in the aerobic environment are improved. Is generated in a well-balanced manner, and the garbage mixed with the treatment medium B is surely decomposed into water and carbon dioxide which are final products. In the apparatus of the present invention, the stationary blades 33a, 33b and the rotary blades 34a, 34b, which are arranged side by side in two stages, respectively discharge the finely crushed kitchen waste into the processing tank 4 as described above. The decomposition treatment is carried out promptly, and a high processing capacity can be stably obtained.

FIG. 4 shows a fixed blade showing another embodiment of the present invention.
FIG. 33 is an exploded perspective view of 33a, 33b and rotary blades 34a, 34b. As shown, in this embodiment, the blade surfaces of the rotary blades 34a, 34b,
That is, the sliding contact surface with each separate fixed blade 33a, 33b is a rough surface, in this case, between the fixed blade 33a and the rotary blade 34a, and between the fixed blade 33b and the rotary blade 34b. The garbage is crushed in such a manner that the garbage is torn off, the garbage after crushing has a large surface area, and the area to which microorganisms can adhere after being mixed with the treatment medium B is further increased. High throughput can be obtained.

In this embodiment, each pair of fixed blades
Although the configuration provided with 33a, 33b and rotary blades 34a, 34b has been described, more fixed blades and rotary blades may be provided, which can further improve the processing capacity.

Further, the constitution of the treatment tank 4 and the stirring means inside the treatment tank 4 is not limited to the above-mentioned constitution, and for example, the rotary treatment tank 4 rotating about a horizontal axis or a vertical axis.
Alternatively, the processing medium B may be internally stirred by rotating the processing tank 4 itself.
