[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposal apparatus capable of decomposing organic substances (such as garbage and cooking effluent) generated mainly in a kitchen at home with microorganisms and flowing the garbage through a sewer pipe. .

[0002]

2. Description of the Related Art Various types of conventional garbage disposal apparatuses have been considered, such as an apparatus for drying and reducing weight, an apparatus for incineration, and an apparatus for decomposition 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 be flowed to a sewer pipe without maintenance.

[0003]

Conventional garbage disposal apparatuses include those that dry, reduce the weight, those that are incinerated, those that are decomposed by microorganisms, and the like. It is necessary to maintain the residue and medium after transportation and treatment, and it may cause odor in the room or cause dripping during transportation,
It was not easy to use. In addition, the one that is provided with crushing means and the like under the sink to improve the usability is that high concentration biochemical oxygen demand (BOD) and solid matter flow into the sewer pipe, clogging the sewer pipe, and polluting the river. The burden on the treatment capacity of the sewage treatment plant will increase.

The present invention solves the problems of the conventional food waste processing apparatus, and can perform the processing on the spot in the kitchen where kitchen garbage is generated, and further eliminates the need for maintenance and post-processing. In addition, it reduces the biochemical oxygen demand (BOD) of kitchen waste and kitchen wastewater so that it can be directly drained to the sewer pipe, which can greatly improve the household work of garbage disposal. The object of the present invention is to provide a food waste processing device that does not pollute the room due to odor or dripping during transportation.

[0005]

Means for Solving the Problems The present invention is directed to a crushing means provided in a kitchen sink, an adjusting tank for temporarily storing organic matter such as food waste crushed by the crushing means, and an adjusting tank located below the adjusting tank to store the organic matter. A decomposition tank for aerobically decomposing by microorganisms, a water tank located below the tank for storing water that has passed through these tanks, a partition plate having an appropriately sized hole and separating the tank, A pump device for feeding the water in the water tank to the adjusting tank, a stirring means for stirring the crushed organic matter in the adjusting tank, and a blowing means for passing outside air into the decomposition tank, The oxygen required for the microorganisms to aerobically decompose the organic matter in the decomposition tank is forcedly passed by the blowing means to promote the decomposition and prevent the generation of a bad odor due to the anaerobic decomposition. .

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION The invention according to claim 1 of the present invention is
The crushing means installed in the kitchen sink, the adjustment tank that temporarily stores organic substances such as food waste crushed by the crushing device, and the filter tank that is located under the adjusting tank and on which the microorganisms are implanted are filled, and the organic matter is aerobically aerated by the microorganisms. Partitioning plate that separates the above-mentioned tanks, which has a decomposition tank for physically decomposing, a water tank that is located below it, that stores water that has passed through these tanks, and that connects to the sewer pipe, and a hole of an appropriate size A pump device for feeding the water in the water tank to the adjusting tank, a stirring means for stirring the crushed organic substances in the adjusting tank, and a blowing means for passing outside air into the decomposition tank. is there. Then, the food waste, the juice content and the kitchen drainage which have been crushed by the crushing means enter the adjusting tank, and the solid content among them stays in this tank because of the partition plate. Further, the liquid content and the fine solid content enter the decomposition tank, and the organic matter of the liquid content and the fine solid content are decomposed by the microorganisms which are implanted on the filter bed of this tank. The water that has been decomposed and the dissolved liquid of organic matter that cannot be decomposed fall down, are temporarily stored in the water tank, and are returned to the adjusting tank by the pump again. Are decomposed by microorganisms and are discharged to the sewer pipe. At this time, the solid content accumulated in the adjusting tank is gradually fined by a stirring means such as a stirring rod or is dissolved by the circulating liquid content, and gradually falls toward the decomposition tank. This is because when a large amount enters the decomposition tank too quickly, the amount of organic substances that do not decompose and partition increases, and it acts to prevent it from entering the water tank and flowing toward the sewer pipe with high concentration,
If a large solid content remains in the adjusting tank, if the crushed raw garbage enters one after another, it keeps collecting in the adjusting tank and prevents the need for a large adjusting tank. It has the effect of stabilizing the function of microorganisms and improving the decomposition ability by allowing organic substances to fall and spreading over the entire microorganisms. Furthermore, oxygen is required for the microorganisms to aerobically decompose organic matter in the decomposition tank, and therefore, by providing a ventilation means for forcedly passing oxygen between filter beds in the decomposition tank, Not only is it promoted, but it also has the effect of preventing the generation of offensive odors and the like due to anaerobic decomposition.

[0007] The invention according to claim 2 of the present invention is based on claim 1.
The blower means is composed of an intake port connected to the upper space of the adjustment tank, an exhaust port connected to the space between the decomposition tank and the water tank, and an intake means such as an air pump connected to the exhaust port. It is designed to allow the outside air to pass, and the air flow through the decomposition tank is forced to flow from the adjustment tank side to the water tank side. This is the one that sucks from below the clogged partition plate when clogging occurs in the partition plate part of the adjustment tank and liquid such as drainage accumulates in the adjustment tank and air does not pass through the decomposition tank. The force of water pressure (gravitational force) that accumulates also acts, and even a relatively weak suction force draws the liquid into the decomposition tank, making it easier to clear the clogging. However, in the opposite case, a suction force for sucking in the excess hydraulic pressure of the accumulated liquid is required, and the liquid is less likely to fall. As a result, even with a blowing means having a small capacity, there is no clogging, sufficient oxygen can be supplied to the decomposition tank, and the introduced organic substances (raw garbage, etc.) can be aerobically decomposed without problems.

The invention according to claim 3 of the present invention is the invention according to claim 2.
The connection between the water tank and the sewer pipe in the above description has a trap structure, and the exhaust of the intake means is configured to be sent to the space on the sewer pipe side downstream from the trap structure. It is designed to be pumped into the sewer pipe without being discharged to the room so that no unpleasant odor is filled in the room.

The invention according to claim 4 of the present invention is the invention according to claim 1.
An overflow path for directly communicating the adjusting tank with the water tank described in 3 is provided, and its opening is configured such that the adjusting tank side is in the upper space of the adjusting tank and the water tank side is below the accumulated water level. This overflow route prevents the adjustment tank from overflowing and flowing back to the crushing means side or the impossibility of passing air when a large amount of wastewater flows into the adjustment tank at once, or when too much liquid is accumulated in the adjustment tank. You can However, when the overflow path is provided, the air taken in by the air blowing means passes through this path without passing through the decomposition tank. In order to prevent this, the opening on the water tank side is configured to be below the water level, and air is passed through the decomposition tank by a water seal so that organic substances can be sufficiently decomposed.

(Embodiment) An embodiment of the present invention will be described with reference to FIG.

In FIG. 1, reference numeral 1 is a sink, and a draining port 3 of a sink 2 is provided with a crushing means 4. The crushing means 4 and the garbage processing tank 5 are connected by a pipe 7 having a trap portion 6. The garbage processing tank 5 has a substantially cylindrical shape,
The partition plates 8 and 9 separate the adjustment tank 10, the decomposition tank 11 and the water tank 12. The partition plate 8 is composed of a mesh-like wire mesh, and the partition plate 9 is composed of a disc with holes. A shaft 13 penetrates through the central portions of the adjusting tank 10 and the decomposition tank 11, and stirring rods 14 are provided at several places perpendicular to the shaft 13 so that they can be rotated by a drive motor 15. The decomposition tank 11 is filled with a filter medium 16 on which microorganisms land.

The bottom portion 17 of the water tank 12 is connected to the suction side of the circulation pump 18, and the discharge side of the circulation pump 18 is connected to the water spray nozzle portion 19 provided on the top surface 10a of the adjustment tank 10. Similarly, the intake port 20 is provided on the top surface 10a of the adjusting tank 10.
There is an overflow path 22 in the side surface of the food waste processing tank 5, an opening 23 on the upper end side of the path 22 is arranged above the side surface of the adjusting tank 10, and an opening 21 on the lower end side of the path 22 is provided. Are arranged below the water level line A of the aquarium 12. Further, the water tank 12 is divided into two rooms by a partition 24 extending below the water level line A, and one room 25 leads to the decomposition tank 11,
The other room 26 is connected to a sewer pipe 28 by a pipe 29. Further, 30 is an air pressure pump, and the exhaust port 11 on the intake side faces the space 11a between the water tank 12 and the decomposition tank 11.
The discharge side is connected to the space portion 11b of the chamber 26 of the water tank 11 by pipes 31 and 32, respectively.

The operation of the food waste processing apparatus configured as described above will be described. When the garbage generated in the kitchen is thrown into the crushing means 4, the power is turned on and the water is poured while crushing, the crushed garbage and the water pass through the pipe 7 and the adjusting tank 10 of the garbage processing tank 5. to go into. The crushed food waste is agitated by the agitating rod 14, and the thing larger than the opening of the wire mesh of the partition plate 8 remains on the adjusting tank 10, and the fine solids and liquid components gradually enter the decomposition tank 11. go. These liquids and fine solids enter the decomposition tank 11, and the organic substances are decomposed by the microorganisms that are implanted on the filter medium 16 in this tank. Then, the decomposed water and the liquid content in which the undecomposed organic matter is dissolved are temporarily stored in the water tank 12 and returned to the adjusting tank 10 by the circulation pump 18. When it is returned to the adjusting tank 10, the sprinkling nozzle portion 1 arranged on the upper part of the tank 10.
Water is sprayed from 9. Then, as the same thing is repeated, most of the organic substances in the garbage are decomposed by microorganisms, and the BOD concentration is considerably reduced. Then, when the water level in the aquarium 12 rises to a certain degree, the sewer pipe 2 passes through the pipe 29.
It is poured out toward 8.

Further, the outside air is sucked from the intake port 20 of the adjusting tank 10 by the pressure feed pump 30, and the partition plate 8 and the decomposition tank 11 are connected.
It passes through the partition plate 9 together with the carbon dioxide generated while passing through the space between the filter media 16, and is sucked into the pressure feed pump 30.
Then, it is sent to the space portion 11b of the room 26 of the aquarium 12, and flows toward the sewer pipe 28 through the pipe 29. The stirring rod 14 also stirs the filter bed 16 in the decomposition tank 11 and scrapes off the microorganisms, so that the filter medium 16 is kept in a state where air can always pass through. Further, when a large amount of water comes into the adjusting tank 10 at once, it flows into the water tank 12 through the overflow path 22 from the opening 23.
In this way, the microorganisms finally decompose the organic substances of the garbage into water and carbon dioxide and flow them to the sewer pipe 28 simply by throwing the garbage into the crushing means 3. There is no need for transportation.

[0015]

According to the first aspect of the present invention, the solid content accumulated in the adjusting tank is gradually made finer by the stirring means such as a stirring rod, or is dissolved by the circulating liquid content while gradually being dissolved. I am trying to fall toward the decomposition tank. This is because if a large amount enters the decomposition tank too quickly, the amount of organic substances that do not decompose and partition will increase, and it will prevent it from entering the water tank and flowing to the sewer pipe with a high concentration, and the adjustment tank with a large solid content. If the crushed raw garbage comes in one after another, it will be accumulated in the adjusting tank more and more, and as a result, a large adjusting tank will be required, which is effective in preventing the main body from becoming too large. Also, by rotating the stirring rod,
The solid matter in the adjusting tank is evenly dispersed on the partition plate, and the organic matter is uniformly dropped from the adjusting tank to the decomposition tank so that it spreads over the entire microorganisms in the decomposition tank, eliminating the unevenness of the treatment and improving the decomposition ability. is there. Furthermore, oxygen is required for the microorganisms to aerobically decompose organic matter in the decomposition tank,
Therefore, by providing a blower that forcibly allows air to pass between the filter beds in the decomposition tank, oxygen can be reliably supplied to the microorganisms, the decomposition is promoted, and oxygen becomes insufficient, resulting in anaerobic decomposition such as methane. It is effective in preventing the generation of bad odor.

According to the second aspect of the present invention, since the flow of air passing through the decomposition tank is forced to flow from the adjustment tank side to the water tank side, the partition plate portion of the adjustment tank is clogged. Even when liquid such as waste water is accumulated in the adjusting tank and air does not pass through the decomposition tank, the liquid is drawn into the decomposition tank with a relatively weak suction force, and the clogging is easily eliminated. However, in the opposite case, a suction force for sucking in the excess hydraulic pressure of the accumulated liquid is required, and the liquid is less likely to fall. As a result, there is an effect that even if the blowing means with a small capacity is not clogged, sufficient oxygen can be supplied to the decomposition tank, and the introduced organic substances (raw garbage, etc.) can be aerobically decomposed without problems.

According to the third aspect of the present invention, the air having a slight odor which has passed through the decomposition tank is pumped into the sewer pipe without being discharged into the room, and the unpleasant odor is discharged into the room. There is an effect to prevent.

In the invention according to claim 4 of the present invention, when a large amount of drainage flows into the adjusting tank at once, or when too much liquid is accumulated in the adjusting tank, the adjusting tank overflows and flows back to the crushing means side. To prevent this, an overflow path is provided that directly connects the adjusting tank and the water tank. When this path is provided, the air taken in by the blowing means passes through this path without passing through the decomposition tank. In order to prevent this, there is an effect that the opening on the water tank side is configured to be below the water level, and air is passed through the decomposition tank by a water seal so that the organic substances can be sufficiently decomposed.

Then, the kitchen waste can be processed on the spot where the garbage is generated, the garbage can be treated on the spot, and after the maintenance and the treatment, there is no need to dispose of the garbage, and the biochemical oxygen demand (BOD) of the garbage and kitchen wastewater. It reduces the amount of waste, etc., and allows it to flow directly to the sewer pipe, which can greatly improve the household work of garbage processing and also does not pollute the room with odors or dripping during transportation. A processing device is provided.
