Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a garbage disposal device for decomposing garbage.

[0002]

2. Description of the Related Art Conventionally, as this type of garbage disposal, there is one that crushes and dewaters kitchen waste and automatically discards it in a garbage bag or the like, for example, Japanese Patent Laid-Open No. 4-156959 (B02C 21/00). )
Etc. have been proposed. However, in this method, it is necessary to dispose of the kitchen waste stored in a garbage bag or the like, which requires a lot of time and labor for disposal, and poses a problem regarding environmental protection.

[0003] In order to solve these problems, a kitchen waste disposal apparatus for disposing of kitchen waste in a processing tank containing a processing medium for culturing microorganisms and decomposing the kitchen waste with microorganisms is a practical application.
It was proposed in Japanese Patent No. 1291 (B09B 3/00). In this kitchen waste treatment device, in order to improve the kitchen waste treatment efficiency, a heater is arranged on the side surface of the treatment tank or hot air is supplied to the side surface of the treatment tank to maintain the temperature inside the treatment tank at a temperature at which the activity of microorganisms is activated. It is like this.

However, in the above structure, since the entire inside of the processing tank is warmed by the heater disposed on the side surface of the processing tank, the heating efficiency is poor and it is difficult to heat the central portion of the processing medium to a sufficient temperature. In addition, when the heater temperature is raised to heat the central portion of the processing medium to a sufficient temperature, the processing bath is heated to a high temperature.
There was a problem that the life of the processing tank was shortened.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned drawbacks, and an object of the present invention is to provide a garbage disposal device capable of efficiently decomposing garbage with a simple structure.

[0006]

The first means of the present invention is to:
A treatment tank for accommodating a treatment medium for culturing microorganisms for decomposing garbage, and a stirring blade disposed in the treatment tank and rotated by an electric motor to mix the treatment medium and the garbage,
The stirring blade is made of a highly heat-conductive material, and the stirring blade is provided with heating means for heating the processing medium.

A second means of the present invention is a treatment tank for accommodating a treatment medium for culturing microorganisms for decomposing garbage, and a treatment tank disposed in the treatment tank and driven to rotate by an electric motor so as to separate the treatment medium and the garbage. A stirring means for mixing is provided, and heating means for heating the processing medium in a direction substantially orthogonal to the rotation axis of the stirring blade is provided between the opposing side walls of the processing tank.

[0008]

According to the first means, the garbage thrown into the treatment tank through the garbage feeding port is mixed with the treatment medium by the rotation of the stirring blade and decomposed by the microorganisms generated in the treatment medium. In the treatment medium, microorganisms attached to the garbage, particularly nematodes, protozoa and bacteria, propagate and decompose the garbage.

The inside of the treatment tank is heated to a temperature higher than the outside temperature due to the heat generated by the decomposition action of the garbage, but the temperature is low enough to hinder the activity of microorganisms in winter, but the treatment medium is heated on the stirring blade. By providing a heating means to
The stirring blade also serves as heat radiation of the heating means, uniformly heats the treatment medium, activates the microorganisms, and improves the garbage disposal capacity.

According to the second means, the heating means activates the microorganisms in the treatment medium to improve the garbage treatment capacity, and the heating means is arranged in a direction substantially orthogonal to the rotation axis of the stirring blade. Thus, the heating means also serves to reinforce the processing tank and prevents the processing tank from being deformed or damaged.

Next, the circuit will be described with reference to FIG.
67 is a switch circuit having a switch mounted on the substrate 47, 68 is a detection means such as a micro switch for detecting the opening of the lid 57, and 69 is a first temperature sensor for detecting the temperature of the processing medium 2 of the processing section 3. , 70 is a second temperature sensor for detecting the outside air temperature, 71 is a control circuit consisting of a microcomputer for inputting the signals from the switch circuit 67, the detecting means 68, the first temperature sensor 69 and the second temperature sensor 70. 9, a motor driving unit 72 for controlling driving, a first heater control unit 73 for controlling energization of the first heating unit 21, and a heater for the second heating unit 26.
The second heater control section 74 for controlling the energization of 29 is controlled.

When the kitchen waste is processed, the lid 57 is opened, the kitchen waste is dropped from the kitchen input port 40 to the inclined surface 41, and the kitchen waste is poured into the processing tank 1 together with water. At this time, the lid 57 is opened so as to cover the operation portion 54 as shown in FIG.
The operation unit 54 will not be operated by mistake with the lid 57 opened. Further, even if the operating section 54 is operated with the lid 57 opened, the detection means 68 detects the opening of the lid 57, and the control circuit
Since 71 deenergizes the electric motor 9, the stirring blade 11 does not rotate with the lid 57 opened.

When the garbage is thrown in, the lid 57 is closed and the operating portion 54 is operated. In this state, the control circuit 71
Receives a signal indicating that the lid 57 is closed from the detecting means 68, operates the operating unit 54 to rotate the electric motor 9 in the normal direction, and rotates the stirring blade 11 in the direction of the solid arrow shown in FIG. Stirring blade 11
Rotates toward the V-shaped ridgeline side of the stirring blade 13, so that the kitchen waste and the processing medium 2 are easily pushed in the axial direction and rotate with a relatively small load. Further, since the stirring blade 13 is curved toward the ridge line side, the kitchen waste located on the processing medium 2 is efficiently drawn into the processing medium 2 and is efficiently mixed with the processing medium 2 in a short period of time. Furthermore, since the stirring blades 13 are arranged in a spiral shape, the kitchen waste and the processing medium 2 are moved not only in the rotation direction but also in the axial direction to stir,
The stirring efficiency is further improved.

The control circuit 71 stops the operation when the electric motor 9 is normally rotated for 20 seconds in the present embodiment for a predetermined time, and after a predetermined time until the electric motor 9 is completely stopped, 5 seconds elapses in the present embodiment. After that, the electric motor 9 is rotated in the reverse direction, and the stirring blade 11 is rotated in the direction of the broken line arrow shown in FIG. Since the control circuit 71 reversely rotates the electric motor 9 after the electric motor 9 is completely stopped, the electric motor 9
The back electromotive force does not occur at the time of starting, and the durability of the electric motor 9 can be improved. When the electric motor 9 is in the reverse rotation state, the stirring blade 13 stirs the garbage and the processing medium 2 while pushing them to the outer periphery, and crushes the garbage with the side wall of the processing tank 1. This rotation direction has a larger load than the rotation in the normal rotation direction, but the crushing ability is improved.

The control circuit 71 reverses the electric motor 9 for a certain period of time, 20 seconds in the present embodiment, and causes the electric motor 9 to normally rotate again after the predetermined time until the electric motor 9 is completely stopped. The normal rotation and the reverse rotation are alternately repeated, and the operation is stopped when a total of 20 minutes has passed.

In the processing medium 2 of the processing section 3, microorganisms, particularly nematodes, attached to the kitchen waste by discarding the kitchen waste in the processing tank 1,
Protozoa and bacteria propagate, and these microorganisms decompose garbage into water and carbon dioxide gas and extinguish it. Since the kitchen waste discarded in the processing tank 1 is crushed between the stirring blade 11 and the side wall of the processing tank 1, the kitchen waste decomposes and disappears in a relatively short time. Also, the processing medium 2
Since the temperature is maintained at a temperature at which the microorganisms are activated by the first and second heating means 21 and 26, the activation of the microorganisms is activated, and the decomposition treatment efficiency of the garbage is further improved.

Based on the output of the second temperature sensor 70, the control circuit 71 causes the electric motor 9 to rotate forward every predetermined time when the outside air temperature falls below a predetermined temperature, which in this embodiment falls below 10 degrees. The stirring blade 11 is rotated in the direction of the solid arrow shown in FIG. Since the rotating shaft 12 and the stirring blade 13 are made of a material having high heat conductivity, the heat of the first heating means 21 is applied to the stirring blade.
It is efficiently transmitted from 13 to the processing medium 2 and uniformly heats the processing medium 2 as the stirring blade 11 rotates. Also, the stirring blade 11
Is rotated in the direction of the solid line arrow shown in FIG. 5, the load applied to the processing tank 1 and the processing medium 2 is relatively small, and the processing tank 1
It is possible to suppress damage such as the above and miniaturization of the processing medium 2.

The water supplied to the treatment tank 1 together with the garbage is
The water generated by decomposing the kitchen waste passes through the purifying unit 4 and is drained to the drainage unit 31. This water contains components that are produced in the process until the garbage is completely decomposed, that is, lower fatty acids such as acetic acid and propionic acid, sulfur compounds such as hydrogen sulfide and methyl sulfide, nitrogen compounds such as ammonia, and acetaldehyde. However, this component is purified by the purification unit 4
It is decomposed by microorganisms, especially bacteria, which propagate in the treatment medium 2, purified, and discharged to the drainage section 21.

Since almost no air is supplied, anaerobic microorganisms are generated in the treatment medium 2 of the purification section 4, but the decomposition of the anaerobic microorganisms does not generate much heat and the temperature of the purification section 4 is treated. It becomes lower than the temperature of the part 3. In this embodiment, since the heating means 18 is provided in the purifying unit 4, it is possible to raise the temperature of the purifying unit 4 and activate the activity of microorganisms in the purifying unit 4, thereby improving the purifying action. You can

With the rotation of the stirring blade 11, the processing medium 2 is compressed and solidified by the stirring blade 13, and kitchen waste, especially kitchen waste containing a large amount of difficult-to-decompose components such as starch and gluten, exceeds the capacity for treating microorganisms. When discarded, the water permeability between the treatment section 3 and the purification section 4 on the outer periphery of the stirring blade 13 deteriorates,
Since water passages are formed on both sides of the treatment tank 1 from the treatment section 3 to the purification section 4, the water in the treatment section 3 is drained to the purification section 4 through the water passage, and water is accumulated in the treatment section 3. It does not adversely affect the growth of microorganisms cultured in the treatment medium 2 of the treatment section 3.

The water drained to the drain section 31 is drained from the drain hose through the drain port 35. When the partition plate 32 and the drainage port 35 that partition the drainage section 31 are clogged, remove the cap 34 from the drainage tube 33 and insert a brush or the like into the drainage section 31 through the drainage tube 33 to clean the partitioning board 32. Then, clean the drain port 35.

When repairing the damage of the electric motor 9 and the chain 19, the top plate 39 is removed from the side wall plate 38 and the lower reinforcing plate 36 is removed.
By removing the screw fixing of the side wall plate 38 and pulling out the side wall plate 38 upward, the electric motor 9 and the chain 19 can be easily exposed, and the repair workability can be improved.

Adult pests and larvae have the property of appearing on the treatment medium 2, and even if the adult pests and larvae are mixed with the treatment medium 2 by the rotation of the stirring blade 11, they will be re-introduced after a certain amount of time. Adult pests and larvae emerge on the treatment medium 2. Therefore, the control circuit 81 performs this operation after a fixed time from the stop of the operation of the electric motor 9, that is, the time required for most of the pests mixed in the treatment medium 2 to come out on the treatment medium 2 by the rotation of the stirring blade 11. In the example, 3 hours after 1 hour
The heating means 75 is heated. Then, when it is detected that the space above the processing medium 1 in the processing tank 1 has reached a temperature at which the adults and larvae of insects such as flies are killed, 50 degrees or more, based on the output of the third temperature sensor 80, The control circuit 81 keeps the space above the treatment medium 2 in the treatment tank 1 for a predetermined time, 5 minutes in the present embodiment, at a temperature at which adult pests and larvae are not killed and microorganisms in the treatment medium 2 are not killed. About 50 degrees to 65
