Description

  The present invention relates to a garbage disposal apparatus that decomposes garbage with microorganisms.

In recent years, a number of techniques relating to garbage processing and garbage processing apparatuses have been developed. As a method for treating garbage, for example, the inside of a decomposition treatment tank in which the garbage is stored is heated and stirred to promote the activation of microorganisms, thereby decomposing the garbage and composting (for example, Patent Documents) 1), and those that decompose and extinguish garbage into water and carbon dioxide (for example, see Patent Document 2).
Japanese Patent Laid-Open No. 9-314115 JP 2000-354849 A

  However, in the method of treating garbage, which decomposes and extinguishes garbage, heat, water, and carbon dioxide are generated in the process of microorganisms decomposing the garbage. Therefore, in the decomposition treatment tank, the temperature and humidity are increased, and the oxygen concentration of the air is decreased. As a result, there has been a problem that the ability to decompose microorganisms in the decomposition treatment tank is reduced, and it takes time to decompose garbage.

  Therefore, in view of the above problems, the present invention activates the activity of microorganisms and improves the decomposition treatment capacity by adjusting the oxygen concentration, temperature and humidity in the decomposition treatment tank in which the garbage and microorganisms are accommodated. It is an object of the present invention to provide a garbage disposal device that can be used.

  In order to solve the above-mentioned problems, the invention of claim 1 is a garbage processing apparatus for decomposing garbage with microorganisms, comprising a decomposition treatment tank in which the garbage and microorganisms are stored, and air in the decomposition treatment tank. A circulation path for circulation and an oxygen generator for activating the activity of microorganisms by increasing the oxygen concentration in the air, the decomposition treatment tank has a stirring means for stirring the input garbage, The circulation path includes a blower for circulating air and a cooler and a heater for temperature adjustment and dehumidification of the air.

  Thereby, the oxygen concentration, temperature, and humidity of the air in the decomposition treatment tank in which the garbage and the microorganisms are accommodated can be adjusted to be optimal for the activity of the microorganisms. As a result, the ability to decompose garbage from microorganisms can be stably maintained, and the garbage can be quickly decomposed.

  The invention of claim 2 is characterized in that, in the invention of claim 1, the oxygen generator raises the oxygen concentration in the air to 25 to 35%.

  Thereby, the oxygen concentration of the air in a decomposition processing tank can be made suitable for the activity of microorganisms. Moreover, since the oxygen concentration in the air is only increased by about 10%, an inexpensive oxygen generator can be used, and the manufacturing cost of the garbage processing apparatus can be suppressed.

  In invention of Claim 3, in the invention of Claim 1 or 2, the temperature in a decomposition processing tank was adjusted to 25-30 degreeC with the cooler and the heater.

  Since the inside of the decomposition treatment tank is adjusted at a temperature closer to room temperature than the conventional device (around 40 ° C), the temperature adjustment by the cooler and the heater can be reduced, and the running cost of the garbage processing device is reduced. Can be suppressed.

  The present invention can adjust the oxygen concentration, temperature, and humidity of the air in the decomposition treatment tank in which raw garbage and microorganisms are accommodated to an optimum value for activating the microorganisms. For this reason, the ability to decompose garbage by microorganisms is increased, and the garbage can be decomposed quickly.

Moreover, as the microbial bed 70 on which the microorganisms are implanted, those having a large number of micropores on which the microorganisms can be implanted, being hardly decomposed by the microorganisms, and being less consumed by stirring are preferable. Specifically, wood chips and rice husks obtained from deciduous trees are suitable.

  As shown in FIG. 4, the bottom of the decomposition treatment tank 24 is formed in a semi-cylindrical shape having a semicircular cross-sectional shape that protrudes downward. As shown in FIG. 2, a stirring means 30 for stirring the garbage 68 and the fungus bed 70 is attached to the lower part of the decomposition treatment tank 24.

  The stirring means 30 is roughly divided into a stirring member 32 and a drive device 34. The agitating member 32 is configured by agitating blades 38 attached to a rod-like rotating shaft 36, and the driving device 34 includes a motor 40 and a small gear attached to the driving shaft of the motor 40 as shown in FIG. 42, a large gear 44 attached to the rotary shaft 36 of the stirring member 32, and a belt 46 stretched around the small gear 42 and the large gear 44.

  The stirring member 34 is spanned below the opposing side surfaces of the decomposition treatment tank 24 and is rotated by a driving device 34 disposed on the side of the decomposition treatment tank 24. Moreover, since the bottom part of the decomposition treatment tank 24 according to the present embodiment is formed in an anti-cylindrical shape, the garbage 68 and the fungus bed 70 accommodated in the decomposition treatment tank 24 are uniformly stirred by rotating the stirring member 34.

  Hereinafter, the operation of the garbage processing apparatus 10 according to the present embodiment will be described with reference to FIG. When the lid 14 of the garbage disposal apparatus 10 is opened and the garbage 68 is introduced from the inlet 18, the garbage 68 is accommodated in the decomposition treatment tank 24. At this time, the stirring member 34 in the decomposition treatment tank 24 is rotated by the driving device 34, and the garbage 68 and the fungus bed 70 are stirred and mixed. Thereafter, the garbage 68 thrown into the decomposition treatment tank 24 is decomposed into carbon dioxide and water by microorganisms to generate heat. When the garbage 68 is decomposed, the stirring means 30 is driven, and air for activating microorganisms is taken into the microbial bed 70, and moisture generated by the decomposition of the garbage 68 is also removed. Escape into the air. As a result, the carbon in the decomposition treatment tank 24 increases due to the decomposition of the garbage 68, so that the oxygen concentration decreases, and the humidity and temperature increase due to moisture and heat generated by the decomposition.

  In the garbage processing apparatus 10 according to the present embodiment, the air in the decomposition treatment tank 24 is sent from the air discharge port 26 to the circulation path 50 by the blower 52. At this time, dust contained in the air is removed by the filter 62 attached to the air outlet 26.

  Thereafter, the air fed into the circulation path 50 is adjusted to a desired temperature by the cooler 54 and the heater 56. In the garbage processing apparatus 10 of this embodiment, a temperature sensor (not shown) is attached to the decomposition treatment tank 24, and the ambient temperature in the decomposition treatment tank 24 is adjusted to about 27 ° C. In the garbage processing apparatus 10 of the present embodiment, the temperature in the decomposition treatment tank 24 is adjusted to a temperature closer to room temperature than the conventional apparatus (about 40 ° C.), so the cooler 54 and the heating The temperature adjustment by the vessel 56 can be reduced, and the running cost of the garbage processing apparatus 1 can be kept low. In addition, the cooler 54 can reduce the humidity of the air by condensing moisture in the air. Water generated by dehumidification in the circulation path 50 is discharged from the drain port 60 to the outside of the garbage processing apparatus 10.

  An oxygen generator 58 is disposed in the downstream region of the circulation path 50 and in the vicinity of the air supply port 28. In the present embodiment, the oxygen concentration in the air is concentrated to about 25% by the oxygen generator 58. For this reason, the air sent to the downstream region of the circulation path 50 is increased in oxygen concentration in the air and returned to the decomposition treatment tank 24 from the air supply port 28.
