[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage processing apparatus for decomposing garbage in a garbage processing tank.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, a garbage disposal tank 1 is filled with a garbage disposal material 2, and the garbage disposed in the garbage disposal tank 1 is decomposed by the garbage disposal material 2. BACKGROUND ART Garbage processing apparatuses for processing are known. In this conventional garbage processing apparatus, bacteria inhabit the garbage processing material 2 filled in the garbage processing apparatus, and the garbage is decomposed by the activity of the bacteria. Outside air is supplied into the garbage disposal tank 1 to supply oxygen to bacteria living in the refuse disposal material 2. When the garbage is treated, decomposition reaction heat is generated and the inside of the garbage treatment tank 1 becomes high temperature to activate the microorganisms. However, when taking in outside air to supply oxygen, if cold outside air is supplied as it is, garbage will be removed. Since the temperature in the treatment tank 1 is lowered, a heater 11 is provided in the middle of an outside air supply unit 8 provided with an intake fan 10 for supplying outside air into the garbage treatment tank 1, and the outside air is heated by the heater 11 to generate hot air. As a result, the decomposition process in the garbage processing tank 1 is activated. Further, a surface heater 40 is attached to the outer surface of the bottom of the garbage processing tank 1, and when the temperature in the garbage processing tank 1 is low, the surface garbage is heated by the surface heater 40 and the garbage processing tank 1 is heated.
I try to raise the temperature inside. When the outside air is sucked in, the exhaust gas in the garbage disposal tank 1 is simultaneously exhausted by the exhaust fan 1.
2 exhausts to the outside. In the figure, reference numeral 6 denotes a stirring blade, which stirs and mixes the food waste treatment material 2 and the food waste.

[0003]

In the above-mentioned prior art, the heat of decomposition reaction and the heat heated by the heater 11 and the surface heater 40 are exhausted to the outside by the exhaust fan 12 without being stored. In addition, the heat in the food waste treatment tank 1 is radiated to the outside through the wall of the food waste treatment tank 1.
Since the heat in the garbage processing tank 1 is radiated to the outside in this manner, energy is wasted, and not only the processing capacity is reduced, but also the surface heater 40 is required. I needed something big. Further, conventionally, there has been a problem that the temperature in the garbage processing tank 1 is not stable, the processing is unstable, and the processing capacity is reduced due to a temperature change.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems of the prior art, and it is possible to reduce the amount of heat radiated from the garbage disposal tank to the outside to save energy. An object of the present invention is to provide a garbage disposal apparatus in which the temperature in a refuse treatment tank is stabilized to stabilize the treatment capacity and improve the treatment capacity.

[0005]

According to the garbage disposal apparatus of the present invention, a garbage disposal tank 1 is filled with a garbage disposal material 2 and is put into the garbage disposal tank 1 by the garbage disposal material 2. In the garbage processing apparatus for decomposing garbage, the outer periphery of the garbage processing tank 1 is covered with a heat storage tank 4 containing a heat storage material 3, and the melting point of the heat storage material 3 is set to 30 ° C to 60 ° C. It is a feature. With such a configuration,
The decomposition reaction heat generated in the garbage processing tank 1 is suppressed from being radiated to the outside, and the heat is stored in the heat storage material 3 of the heat storage tank 4 on the outer peripheral portion of the garbage processing tank 1. When the temperature of the garbage disposal tank 1 decreases, the garbage disposal material 2 in the garbage disposal tank 1 can be heated from the heat storage tank 4, whereby the temperature in the garbage disposal tank 1 can be reduced without using a surface heater. It can be kept at a certain temperature or higher. In addition, the heat storage material 3
Since the melting point is 30 ° C to 60 ° C, the garbage disposal tank 1
Keep the temperature above a certain level suitable for garbage disposal
Is what you can do.

It is also preferable to cover the outer periphery of the heat storage tank 4 with a heat insulating layer 5. With such a configuration, the heat stored in the heat storage tank 4 is radiated to the outside by the heat insulating layer 5.
And the heat storage material 3 in the heat storage tank 4
The heat exchange can be performed efficiently only through the heat exchanger.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a schematic diagram of a garbage processing apparatus. The garbage processing tank 1 is provided with rotatable stirring blades 6 therein, and the garbage processing tank 1 is further filled with a garbage processing material 2. The garbage processing material 2 filled in the garbage processing tank 1 is like a sawdust-like woody strip called a biochip in which microorganisms have inhabited, and the garbage processing material 2 is conventionally known. (For example, Japanese Patent Publication No. Hei 2-10398, Japanese Patent Publication No. Hei 2-30760, and Japanese Utility Model Publication No. Hei 3-22385) can be used. The upper part of the garbage processing tank 1 is provided with an upper space 7 in which the garbage processing material 2 is not filled. Although not shown, the upper part of the garbage processing tank 1 is provided with an inlet for introducing garbage,
A lid (not shown) is provided at the opening so as to be freely opened and closed.

The upper space 7 provided above the garbage disposal tank 1
Is provided with an outside air supply unit 8 for supplying outside air and an exhaust unit 9 for discharging exhaust gas in the upper space 7.
The outside air supply unit 8 is provided with an intake fan 10 and a heater 11. Further, the exhaust unit 9 is provided with an exhaust fan 12. The outer periphery of the kitchen waste treatment tank 1 is covered with a heat storage tank 4 containing a heat storage material 3. The heat storage material 3 used here has a melting point of 30 ° C. to 60 ° C. Further, the outer peripheral portion of the heat storage tank 4 is covered with a heat insulating layer 5 made of a heat insulating material, so that heat stored in the heat storage tank 4 is prevented from being radiated to the outside. Therefore, the heat storage material 3 in the heat storage tank 4 exchanges heat with the garbage processing tank 1 to store heat generated in the garbage processing tank 1, and the temperature in the garbage processing tank 1 is reduced. When the temperature decreases, the heat stored in the heat storage material 3 of the heat storage tank 4 is radiated to the garbage processing tank 1 to heat the garbage processing material 2 in the garbage processing tank 1.

In the process of decomposing garbage thrown in from the upper inlet of the garbage disposal tank 1, the garbage is decomposed by the activity of microorganisms living in the garbage processing material 2. However, in this case, the garbage disposal material 2 and the garbage are agitated and mixed by rotating the stirring blades 6 at regular time intervals to effectively perform the garbage decomposition process. The upper space 7 in the garbage processing tank 1 collects exhaust gas such as carbon dioxide and moisture generated during garbage processing by the garbage processing material 2. Here, the exhaust fan 12 and the intake fan 10 are operated at regular intervals.
When the exhaust fan 12 is operated, the exhaust gas collected in the upper space 7 provided above the garbage processing tank 1 is exhausted from the exhaust unit 9 to the outside. Although not shown, the exhaust gas exhausted from the exhaust unit 9 may be exhausted after being deodorized by a deodorizer. In the present invention, the exhaust fan 12 is set so as to reduce the wind power as much as possible to suppress heat radiation.

When the intake fan 10 is operated, fresh fresh air is supplied from the outside air supply unit 8 into the garbage processing tank 1, and microorganisms inhabiting the garbage processing material 2 in the garbage processing tank 1 are removed. It supplies oxygen. In other words, it supplies oxygen necessary for the decomposition (fermentation) of garbage. By the way, when garbage is decomposed by the garbage processing material 1, decomposition heat is generated. Conventionally, the heat of the decomposition treatment was directly radiated to the outside from the wall of the garbage disposal tank 1, but in the present invention, the heat radiated from the treatment tub 1 is used as the heat of the garbage disposal tank 1.
Is stored in the heat storage material 3 in the heat storage tank 4 which covers the outer peripheral portion of the heat storage tank. On the other hand, when the temperature in the garbage processing tank 1 decreases and becomes lower than the temperature of the heat stored in the heat storage material 3 in the heat storage tank 4, the heat stored in the heat storage material 3 disturbs the wall of the garbage processing tank 1. Heat is radiated into the garbage disposal tank 1 through the portion, thereby heating the garbage disposal material 2 in the garbage disposal tank 1 and preventing the garbage disposal material 2 from lowering below a certain temperature. Things.

Here, the activity range of the microorganisms that inhabit the garbage processing material 1 in the garbage processing with the garbage processing material 1 is in a range of about 30 ° C. to about 60 ° C. Although the most effective garbage treatment can be performed, as described above, the heat storage material 3 has a melting point of 30 ° C to 6 ° C.
When the temperature in the garbage disposal tank 1 is lowered by using the garbage disposal tank at 0 ° C., the heat stored in the heat storage material 3 of the heat storage tank 4 is radiated to the garbage disposal tank 1 to garbage. The garbage disposal material 2 in the treatment tank 1 is heated, and thereby the garbage disposal material 2 is heated.
Is higher than the temperature required for the garbage disposal material 2 to be activated (that is, 3
0 ° C. or higher).
The garbage processing material 2 does not fall into the inactive temperature range, avoids a decrease in processing capacity, and as a result, can improve the processing capacity.

FIG. 2A shows a temperature change in the garbage processing tank 1 when the outer periphery of the garbage processing tank 1 is covered by the heat storage tank 4 in which the heat storage material 3 is placed without providing a surface heater. A graph is shown, and FIG. 2B shows a graph showing a temperature change in the garbage processing tank 1 when the heat storage tank 4 is not provided. As is clear from the graph of FIG. 2, in the case where the outer periphery of the food waste treatment tank 1 is covered with the heat storage tank 4 as in the present invention, the food waste treatment material 2 is almost at a temperature near the melting point of the heat storage material 3. It is evident that it is kept constant and once in operation does not come into the inert temperature range, the throughput is improved.

Decomposition heat generated in the garbage processing tank 1 is stored in the heat storage tank 4, and when the temperature in the garbage processing tank 1 decreases (for example, at night), the garbage processing is performed from the heat storage tank 4. Since the heat is radiated into the tank 1, there is no waste of heat, and when the temperature in the garbage processing tank 1 decreases, there is no need to heat with a surface heater as in the conventional case (thus, no surface heater is required), and running costs are reduced. Is reduced.

When the intake fan 10 is operated to supply fresh outside air from the outside air supply unit 8 into the garbage disposal tank 1, if the outside air temperature is low, the heater 11 is turned on to heat the unit. It is supplied as outside air. FIG. 3 shows another embodiment of the present invention. In this embodiment, an auxiliary heating means 20 is connected to the heat storage tank 4. Solar heat or midnight power can be employed as a heat source of the auxiliary heating means 20. The auxiliary heating means 20 prevents the temperature of the heat storage material 3 in the heat storage tank 4 from falling below a certain temperature.
This makes it possible to cope even when the decomposition of the garbage processing material 2 is unstable.
