DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage processing system for processing garbage discharged from a home kitchen or the like. In particular, the present invention relates to a garbage processing system suitable for collectively processing garbage discharged from each house in an apartment house such as an apartment or a condominium.

[0002]

2. Description of the Related Art Garbage is a general term for garbage generated by cooking foods at home or in a cafeteria, such as garbage left over from cooking foods and garbage left over. More specifically, water is mixed with vegetable waste, fish heads and bones, fruit peels, and the like. The water content of garbage is generally said to be 70% to 80%.

[0003] As a method of treating garbage, there have been classical methods such as burying it in the soil of a yard or farmland at home or feeding it to animals such as pigs.
It is. Generally, put the garbage in the triangle corner (net) at the corner of the sink, drain the water, put it in a plastic bag, and take this bag out to a garbage collection place to collect other garbage (paper, etc.). Collect them together and send them to a garbage incinerator where they are incinerated.

[0004] However, recently, garbage disposers for treating garbage at sites where garbage is generated, such as homes and cafeterias, have begun to be used. The recent trend of processing garbage "friendly to the earth" by a more natural processing system,
This is where people want to eliminate the problems typified by the stench in storage at home and in garbage collection sites in the above-mentioned collection and incineration system.

The following three types of garbage disposers are generally used at present. Compost container type: A container with ordinary soil is placed in the corner of the garden, etc., into which garbage is put, and the garbage is decomposed by microorganisms to obtain compost. This compost is used as fertilizer for garden plants. Insufficient soil is removed from the garden and placed in a container. There are no moving parts in the container, and it is essentially the same treatment as the classic “fill in the soil”.

Drying type: Puts garbage in a container equipped with an electric heater or the like and heats it to blow off moisture. After drying,
The volume of the garbage is 1/3 to 1/5 of the original volume, and the juice does not sag or smell, so it is easy to process (put it in a bag and collect it together with paper trash). is there.

[0007] Bio-treatment type: The garbage processing tank is maintained in an environment where bacteria having a high ability to decompose garbage such as aerobic high-temperature bacteria are easily activated, and an arm for stirring and crushing the garbage is provided in the tank. It is a garbage processing machine equipped. Thermophilic bacteria have a temperature of 5
Active at 0-70 ° C. It is also generally practiced to put a fungus culture base material and a water regulating material made of porous woody chips (chips) in the tank.

[0008]

However, in each household of the apartment house, the compost container type among the above-mentioned garbage disposal machines cannot be used. This is because the connection with the soil is too strong.
In addition, the drying type and the bioprocessing type have the following problems. Most garbage disposal machines are installed outdoors because of restrictions on odor and drainage, and a veranda or the like requires an installation space for the treatment machines.

[0009] When processing on a veranda, a considerable odor is also generated, which inconveniences the residents of the next or upper house, which makes it difficult to use. While transporting the garbage that has been drained at the triangle corner of the sink to the processing machine, the room will be polluted by dripping water.

[0010] The remainder reduced in volume by the dry-type garbage disposer must be disposed of as combustible waste after all because there is no garden. Since the price of the processing machine is quite high, it is difficult to purchase each house.

Due to the above-mentioned problems, garbage disposers are rarely used in apartment houses. SUMMARY OF THE INVENTION An object of the present invention is to provide a garbage disposer capable of centrally disposing of garbage from each house of an apartment house without the hassle of transporting the garbage from the kitchen to the disposer.

[0012]

In order to solve the above problems, a garbage disposal system of the present invention treats wastewater containing crushed garbage discharged from a sink provided with a garbage crusher (disposer). A garbage disposal system, comprising a drainage inlet, a belt filter for filtering the input wastewater, filter driving means for driving the belt filter in a longitudinal direction, and a crushed garbage deposited on the belt filter. A crushed garbage removal means for removing the garbage from the belt filter at a position where the crushed garbage is not removed, a filter drying means for drying the belt filter from which the crushed garbage has been removed, and a garbage for eliminating or reducing the volume of the crushed garbage removed from the belt filter. A waste treatment machine, and a drain port for discharging drain water after filtration , wherein the belt filter is
It is a loop type, and the drainage is filtered at the top of the loop.
And falls down the loop after filtration.
Do not hit the belt filter at the bottom of the loop.
Loop lower filter waterproofing means
It is characterized in that

[0013]

[Function] Garbage from the sink of each house is crushed by a disposer and sent to a garbage disposal system together with drainage. In the garbage treatment system, the crushed garbage in the wastewater is caught by a belt filter. The crushed garbage deposited on the surface of the belt filter is moved to a place where drainage does not occur with the movement of the belt filter, peeled off from the surface of the belt filter, and put into a garbage disposer. Thereafter, the belt filter is dried by the filter drying means, and waits for the next filtration.

[0014]

Embodiments of the present invention will be described below. FIG.
It is a mimetic diagram showing the composition of the garbage processing system concerning one example of the present invention. The garbage discharged from the kitchen sink 5 of each house of the apartment house 3 is finely crushed by a disposer 9 attached to the sink 5, and together with drainage, a drain pipe 1 for each house is provided.
1 through the collective drain 13 and the garbage disposal system 1
Sent to Metals such as bottle lids and vinyl-wrapped wire (product name: vinylite, band that clasps the mouth of the bag) may be mixed in the garbage. It is attracted by the magnet 7 attached to the sink and remains in the sink 5 and is removed from the garbage. This is to prevent the lid of the bottle from damaging the rotating blades of the disposer 9.

In the garbage disposal system 1, the wastewater containing the crushed garbage falls down from the wastewater inlet 15 and falls on the belt filter 17. The belt filter 17 is
Nylon mesh or the like (the stitch fineness is, for example, 30 mesh) is in a loop shape. The belt filter 17 is stretched by a support roll 19, a press roll 31, a brush roll 33, a roll 21, and the like.
And driven (sent in the longitudinal direction). Note that the presser roll 31 is under the drainage flow, and the belt filter 17 is recessed downward.

The waste water is filtered at the upper part of the loop of the belt filter 17, and crushed garbage is deposited on the belt filter 17. The belt filter 17 is normally stopped. However, when the accumulation amount of the crushed garbage increases and the entire belt filter 17 becomes heavy, the support roll 19 (which is urged and supported upward by a spring or the like) is slightly lowered. Below the support roll 19, a sensor (garbage accumulation sensor) 20 for detecting the vertical position of the roll is attached. When a predetermined amount of crushed garbage is accumulated and the roll 19 is lowered by its weight, The sensor 20 detects this. Then, the rolls such as the support roll 19 are automatically driven, and the belt filter 17 is fed to the left side in the figure by various lengths. Then, the belt filter 17 above the loop becomes lighter, the support roll 19 rises, the garbage accumulation sensor 20 is turned off, and the driving of the belt filter 17 is stopped.

The belt filter 17 on which the layer of pulverized garbage is placed is brushed by a brush roll 33 so that the layer of garbage floats from the belt filter 17. Thereafter, the garbage deposited layer automatically falls into the garbage disposer 41 disposed at the lower left of the brush roll 33 from above the belt filter 17 that has turned below the brush roll 33.

A fan 35 is provided below the brush roll 33, and extends from the inside of the loop of the belt filter 17 (back side in the filtering direction) to the outside of the loop (front side in the filtering direction).
Send wind toward. This wind also causes the crushed garbage adhering to the belt filter 17 to separate from the belt filter 17 and to fly to the processing tank 45 of the garbage processor 41. The fan 35 is activated by the belt filter 1
7 is automatically performed in conjunction with the driving of the control signal.

The fan 35 also plays a role in drying the belt filter 17. When the belt filter 17 dries, even if a small amount of crushed garbage adheres, no rot occurs, and therefore, generation of offensive odor is suppressed. In this way, the belt filter 17
It automatically becomes clean and reusable. Fan 3
5 may be a fan with a heater to send warm air to the belt filter 17.

The garbage disposer 41 may be a dry type or a bio-type. However, in the case of the dry type, the residue after the reduction processing remains, so that it takes time to process the residue. In the case of a so-called extinguishable bioprocessing machine,
Since hardly any solid residue remains, the trouble of residue treatment can be saved. Furthermore, there is an advantage that the processed product (compost, compost) or waste liquid can be used as a fertilizer, and therefore, a bio-processing type garbage disposer is preferable. In this embodiment, the garbage disposer 41 is of a bio-treatment type. The inside of the processing vessel 45 is rotating the stirring rod 43, also the processing tank 45 by the heating means (not shown), and is heated to a suitable temperature (50-70 ⁰ C) the activities of thermophilic bacteria. As a heat source, electricity, gas, and various kinds of hot exhaust gas can be used.

On the other hand, the wastewater that has passed through the upper filter for filtration enters the loop of the belt filter 17,
It hits the water barrier plate 25, flows on the same plate 25 toward the near side or the far side of the drawing sheet and falls down, and the belt filter 17
Is received by the pan 27 provided below the loop of the pan 27, and flows into the general sewage from the drain port 29 at the center bottom of the pan 27.
Then, the wastewater is treated at a sewage treatment plant together with wastewater from a toilet or the like. In addition, it is conceivable that wastewater containing crushed garbage crushed by the disposer is sent directly to general sewage without any treatment, but depending on the capacity and type of sewage treatment plant,
It is uncommon at present because many treatment plants are not suitable for receiving such wastewater.

The function of the above-mentioned water barrier plate 25 (loop lower part filter waterproofing means) is to prevent drainage from being applied to the belt filter 23 below the loop. When drainage is applied to the lower belt filter 23 from the inside of the loop (from the rear side in the filtration direction), residual solids in the drainage accumulate inside the loop. Since such solids are not easily discharged out of the loop, they may cause troubles such as clogging of each part of the machine and odor. Of course, it is irrational to wet the lower belt filter 23 which has been dried beautifully by the fan 35. The lower belt filter 23 rotates counterclockwise as the garbage processing system 1 operates, and is sent to the upper portion of the loop again to be subjected to filtration of wastewater.

[0023]

As is clear from the above description, the garbage disposal system of the present invention has the following effects. By installing one medium-sized garbage disposal machine in an apartment house, it is possible to collectively process garbage from each household, so if you buy a small garbage disposal machine for each household, You need less budget compared to Also, the processing of discharged compost and the like can be performed collectively. In addition, miniaturization and deodorization of a garbage disposal machine involve various difficulties, and it is difficult to install a garbage disposal machine in each apartment house.

Since the sink of each household and the garbage disposal system are connected by a drain pipe, there is no need to drain the garbage or to handle the garbage to the garbage disposal machine. As a result, there is no possibility of soiling the house while handling garbage.

The garbage disposal system can be of an automatic operation type, and the filter can be automatically cleaned and dried, so that there is no need for manual filter cleaning and operation monitoring. When the loop lower filter waterproof means such as a water barrier is provided, the belt filter that has been cleanly dried does not become dirty with drainage that falls from the upper part to the lower part.

If a magnet is attached to the bottom of the sink, even if metal such as a bottle lid is contained in the garbage, it is attracted to the magnet and removed, so that the failure or stop of the disposer can be prevented. . Therefore, it is not necessary to perform a troublesome repair or return operation.

[0027] As a result of the above, it is possible to solve various problems associated with the processing of garbage in an apartment house at once.
There is significant significance in solving environmental problems and providing comfortable living spaces.
