Description

(4) The present invention relates to a garbage disposal apparatus capable of decomposing organic substances (such as garbage and cooking effluent) mainly generated in a home kitchen with microorganisms and flowing the garbage through a sewer pipe.

Various types of conventional garbage disposal devices are considered, including those that dry, reduce weight, those that are incinerated, and those that are decomposed by microorganisms. However, it is necessary to maintain the residue and the medium after the treatment, and there has been no garbage disposal apparatus that can directly flow to the sewer without maintenance.

In conventional garbage disposal equipment, there are those that dry, reduce the weight, those that are incinerated, those that are decomposed by microorganisms, etc.When processing garbage, draining, transporting to the processing equipment, and residue after treatment In addition, it was necessary to maintain the media and media, and the odor was generated indoors and juice dripping occurred during transportation, which was not convenient. In addition, the crushing means and the like provided under the sink for improved usability include a high concentration of biochemical oxygen demand (BOD) and solids flowing into the sewage pipe, clogging the sewage pipe, polluting the river, This increases the load on the treatment capacity of the sewage treatment plant.

The present invention solves the problems of such a conventional garbage processing apparatus, can perform processing on the spot of a kitchen sink where garbage or the like is generated, further eliminates maintenance and disposal after processing, and further reduces garbage and waste. It also reduces the biochemical oxygen demand (BOD) of kitchen wastewater and allows it to flow directly to the sewer pipes, which can greatly improve the housekeeping work of garbage disposal, as well as odor and transportation. An object of the present invention is to provide a garbage disposal apparatus that does not pollute the room with dripping juice.

The present invention provides a crushing means provided in a kitchen sink, an adjustment tank for temporarily storing organic matter such as garbage crushed by the crushing means, and a lower part thereof, for aerobically decomposing organic matter by microorganisms. A decomposition tank, a water tank located below the tank for storing moisture passing through these tanks, a partition plate having a hole of an appropriate size and separating the tank, and adjusting the water in the water tank. A pump device for sending to the tank, a stirring means for stirring the pulverized organic matter in the adjustment tank, and a blowing means for passing outside air into the decomposition tank, wherein the microorganisms are aerobic in the decomposition tank. By forcibly passing oxygen required for chemical decomposition by a blowing means, decomposition is promoted, and at the same time, generation of offensive odor or the like due to anaerobic decomposition is prevented.

ADVANTAGE OF THE INVENTION According to the garbage processing apparatus of this invention, it can process on the spot of the kitchen sink where garbage etc. generate | occur | produce, and further eliminates the maintenance of the residue after processing and a medium, and the post-processing after processing, It also reduces the biochemical oxygen demand (BOD) of kitchen and kitchen effluents and allows them to flow directly to sewers.

The invention according to claim 1 includes a crushing means provided in a kitchen sink, an adjusting tank for temporarily storing organic matter such as garbage crushed by the crushing means, and a filter medium located below the filter for landing microorganisms. It has a decomposition tank for filling and aerobically decomposing organic matter by microorganisms, and a water tank located below and storing water passing through these tanks and connected to a sewer pipe, and a hole of an appropriate size. A partition plate for separating the tank, a pump device for sending water in the water tank to the adjustment tank, a stirring means for stirring the pulverized organic matter in the adjustment tank, and passing outside air into the decomposition tank. And a blowing means. Then, the garbage, juice, and kitchen wastewater pulverized by the pulverizing means enter the adjusting tank, and the solid content therein remains in the tank due to the presence of the partition plate. In addition, liquids and fine solids enter the decomposition tank, and microorganisms that have settled on the filter bed of this tank decompose organic matter of liquids and fine solids. Decomposed water and dissolved liquids of organic substances that cannot be completely decomposed fall down, are temporarily stored in a water tank, returned to the adjustment tank again by a pump, and most of the organic substances are repeated while the same thing is repeated. Is decomposed by microorganisms and flows out to the sewer. At this time, the solid content accumulated in the adjusting tank is gradually reduced by a stirring means such as a stirring rod, or dissolved by the circulating liquid, and gradually falls toward the decomposition tank. This is because when entering a large amount into the decomposition tank too early, the organic matter that does not decompose is increased, preventing it from entering the water tank and flowing to the sewer pipe with a high concentration, and an adjustment tank with a large solid content If the garbage is crushed one after another, the garbage will collect more and more in the adjustment tank to prevent the need for a large adjustment tank. It has the effect of stabilizing the action of microorganisms and improving the decomposition ability. Furthermore, oxygen is required for the microorganisms to aerobically decompose the organic matter in the decomposition tank, and therefore, by providing a blowing means for forcibly passing oxygen between the filter beds in the decomposition tank, the decomposition is performed. It has the effect of promoting acceleration and preventing the generation of offensive odors and the like due to anaerobic decomposition.

動作 The operation of the garbage processing apparatus configured as described above will be described.

When the garbage generated in the kitchen is put into the crushing means 4 and the water is poured while the power is turned on and crushed, the crushed garbage and water pass through the pipe 7 and are adjusted in the adjusting tank 10 of the garbage processing tank 5. to go into. The crushed garbage is stirred by the stirring rod 14, and the thing larger than the opening of the wire mesh of the partition plate 8 remains on the adjustment tank 10, and other fine solids and liquid components gradually enter the decomposition tank 11. . These liquids and fine solids enter the decomposition tank 11, and the organic matter is decomposed by microorganisms that have settled on the filter medium 16 of this tank. The decomposed water or the dissolved liquid of organic substances that cannot be completely decomposed are temporarily stored in the water tank 12 and returned to the adjustment tank 10 by the circulation pump 18. When the water is returned to the adjusting tank 10, water is sprayed from a watering nozzle unit 19 arranged on the upper part of the tank 10. Then, while the same is repeated, most of the organic matter in the garbage is decomposed by microorganisms, and the BOD concentration is considerably reduced. Then, when the water level in the water tank 12 becomes high to some extent, the water is drained toward the sewer pipe 28 through the pipe 29.

Further, the outside air is sucked from the inlet port 20 of the regulating tank 10 by the pump 30, and passes through the partition plate 9 together with the carbon dioxide generated while passing between the partition plate 8 and the filter medium 16 of the decomposition tank 11. Sucked into. Then, the water is sent to the space 11 b of the room 26 of the water tank 12, and flows through the pipe 29 toward the drain 28.
