In order to treat such food waste at the source, various treatment means have been developed, and among them, a food crusher installed under the kitchen sink of each household to grind and treat food waste has been proposed.

This food crusher is a technology that is installed under a sink in a kitchen and operates after inputting food waste to finely crush the food waste and then discharging the food waste to the outside through a transfer pipe.

This food crushing processor is installed at the bottom of the drain of the sink, uses a grinding blade rotated by an electric motor to grind food waste and then discharges it to the outside through a transfer pipe, so that food waste can be conveniently disposed of. It is to provide user convenience.

Various technologies have been suggested for food waste treatment using food crusher, such as Registered Patent No. 1196428 (October 25, 2012), but only a technology for simply pulverizing food waste at home and discharging it to the outside is being presented, and pulverized food It does not suggest a technology for discharging waste at the source, processing it centrally, and recovering it as a resource material.

In the food waste disposal system of apartment houses using the food crusher of Registered Patent No. 1157025 (2012.06.11.), the food crusher installed under the sink to crush food waste, and the food waste A food waste storage tank located at the end of the transfer pipe and storing the transported food waste and sewage, a watering pump that sucks in the sludge precipitated at the bottom of the food waste storage tank and discharges it to the outside, A centrifugal separator that separates and discharges sludge and wastewater using centrifugal force while drying the sludge transferred through a watering pump, a sludge storage tank that stores the sludge discharged from the centrifugal separator, and processing the sludge stored in the sludge storage tank to produce feed or A technique including a pelletizer for producing compostable pellets is presented.

Only the technology of reusing pulverized food waste as feed by simply depositing pulverized food waste in a storage tank and discharging only the precipitated solid to the outside has been proposed, and suspended solids from sewage containing pulverized food waste remain in the storage tank as it is. There is a problem that the processing efficiency is lowered.

In the food waste generation source centralized treatment resource recovery system of Registration Patent No. 1821571 (2018.01.18.), food waste is cut and shredded by communicating with sink drains (101) of homes, community catering establishments, and businesses, and the cut and shredded food waste is discarded and sewage is discharged. A conveying device for discharging, a solid-liquid separation and reduction device that separates solids and water from food wastes that are connected to the conveying device and introduced through the conveying device by a sewage line and discharges them separately, and separate discharge from the solid-liquid separation and reduction device The solids discharge unit for storing and discharging the solids to be processed, but drying and fermenting functions are added internally, and the treated water separated from the solid-liquid separation and reduction device filters the water introduced through the treated water line with filtered water and delivers it to the drainage chamber below. It is intended to be provided with a filtration chamber to do so, and a drain chamber to receive the filtered water from the filtration chamber and discharge it to the sewer.

However, the filtration chamber in the prior art allows the sewage introduced from the solid-liquid separation and reduction device to be discharged through the external portion, the filter medium, and the inner tube through the drain chamber and discharged to the drain pipe, while cleaning the filter medium and the solids deposited as a result of the cleaning at the same time. There is a problem in that there is a limit to the removal of solids deposited on the filter material in order to collect in the groove so that it can be removed through the lower suction pipe by the suction of the suction pump or to clean the filter medium by the centrifugal force caused by the rotation of the filter chamber. .

The support plate 20 is formed such that it has a certain height while being upwardly opened from the upper surface of the solids collection unit 10, and opens toward the solids induction hole 12 formed in the solids collection unit 10 on one side.

Therefore, the support plate 20 is configured to guide the solids filtered from the sewage to the solids induction hole 12 of the solids collection unit 10, and the inside of the support plate 20 has a spring 31 in the center ) is formed so that the filtration chamber 30 is provided thereon.

That is, the center of the bottom surface of the filtration chamber 30 is elastically supported by the spring 31, and the upper surface of the solids collector 10 to which the support plate 20 is connected has a spring 31 at the center as shown in FIG. The tubular guide protrusion 13 is formed at a certain height so that the lower end of the ) is placed, and the spring 31 is formed on the bottom surface of the filtration chamber 30 to surround the outer circumferential surface. .

As shown in FIG. 4, the filtration chamber 30 separates the outer tube 33 and the outer tube 33 by a predetermined diameter so that the inner tube 34 is provided on a concentric circle, while the outer tube 33 and the inner tube 34 are provided. Filter holes 330 and 340 are formed on the main surface of the tube 34, and the first filter medium 330 is filled between the outer tube 33 and the inner tube 34, and the inner tube 34 ) The inside of the second filter medium 340 is filled, respectively.

The first filter medium 35 and the second filter medium 36 provided in the filtration chamber 30 have different pores, that is, the filter medium on the inside rather than the outside is formed in a shape having more dense pores. At this time, the first filter medium 35 ) is made of a very dense metal net, and the second filter medium 36 is more preferably made of non-woven fabric.

However, the sewage is purified through the filtration holes 330 and 340 formed in the outer tube 33 and the inner tube 34, and the purified sewage flows into the drainage chamber 40 connected to the upper part of the filtration chamber 30. discharged to the drain pipe 60 by

That is, the pump 41 is provided inside the drain chamber 40 so that the sewage purified by the second filter medium 35 filled in the inner pipe 34 of the filtration chamber 30 is forcibly sucked into the drain pipe ( 60), so that the filtration chamber 30 and the sewage filled in the space where the filtration chamber 30 is provided are stably discharged.

The lower end of the drainage chamber 40 is connected to the upper end of the filtration chamber 30 and the main surface in a screw fastening manner so that separation and height adjustment are possible.

In particular, it is more preferable that the pump 41 of the drainage chamber 40 is driven or stopped by the water level of the sewage filled in the filtration chamber 30 .

The present invention is provided at the bottom of a drain in a sink sink to separate wastewater together with finely pulverized food waste, so that the wastewater can be drained into a sewer pipe.

That is, when sewage containing solids flows in, as shown in FIG. 5 , the solids caught on the first filter medium 35 inside the outer pipe 33 in the filtration chamber 30 fall downward, and the solids in the solids collection unit 10 fall down. The solids are discharged to the lower suction pipe 11 through the induction hole 12.

In addition, the sewage is purified while passing through the first filter medium 35 and the second filter medium 36 of the filtration chamber 30, so that the water quality is greatly improved, and is forcibly sucked using the pump 41 to drain the drain pipe 60 ) through which it is discharged.

When the wastewater containing the solids that have undergone the pulverization process is separated from the wastewater for a certain period of time to be discharged, the first filter medium 35 and the second filter medium 36 are naturally contaminated, so the purification efficiency is rapidly reduced.

When the level of sewage in the filtration chamber 30 exceeds a certain level, the pump 41 is automatically driven to forcibly suck the sewage outside the filtration chamber 30 so that the water level is lowered below a certain level.

To this end, a water level sensor (not shown) is provided on the outer circumferential surface of the filtration chamber 30 and the drainage chamber 40 or the outer circumferential surface of a chamber cover (not shown) provided to cover them from the outside, and the level state of the waste water through the water level sensor Accordingly, the driving of the pump 41 is intermittent, and the water pressure difference or the turbidity difference of the sewage is checked at the upper part of the outer tube 33 and the inner tube 34 of the filtration chamber 30, respectively, so that the filtration chamber 30 The replacement or cleaning timing of the first filter medium 35 and the second filter medium 36 is notified to the user or manager.

At this time, when the filter medium replacement or washing time arrives, the controller 50 informs through a warning sound or a terminal such as a smart phone.

However, when the filtration chamber 30 is replaced or a washing signal is generated, the controller 50 automatically or the user manually drives the pump 41 temporarily so that the filtering device of the present invention together with the filtration chamber 30 is accommodated Allow all sewage in the space to be discharged.

In the state in which sewage is completely discharged, first rotate the solids collector 10 so that it descends more to the lower part of the lower suction pipe 11, the filtration chamber placed on the support plate 20 provided on the upper part of the solids collector 10 In (30), the pressing force applied to the drain chamber 40 side is reduced.

Therefore, when the screwing state is released from the drainage chamber 40 by rotating the filtration chamber 30, the filtration chamber 30 is separable from the drainage chamber 40 and the support plate 20 or the solids collection unit 10 Therefore, the filtration chamber 30 is replaced with a new one or cleaned.

At this time, if the first filter medium 35 and the second filter medium 36 provided in the filter chamber 30 are provided to be separable, only each filter medium can be separated and replaced or washed, enabling more economical or easy cleaning work. do.

In this way, the present invention not only contributes to sewage purification by enabling filter media having different pore sizes to purify sewage more cleanly, but also replaces or cleans the filtration chamber 30 at an appropriate time, thereby improving the quality of sewage. It is possible to make economical management possible while keeping the purification efficiency stable.
