Description

Food Waste Separation and Collection System with Cooling Means}

The present invention relates to a food waste separation and collection facility having a cooling means, and more particularly, to separate food waste with cooling means capable of cooling the food waste to prevent corruption and keeping it sanitary and suppressing the occurrence of odor. It relates to a collection facility.

In general, household waste in household waste is increasing in the separate collection rate due to the continuous system and enlightenment, but the amount of food waste is increasing, the treatment method and the solution of the disposal cost has emerged as an important problem.

As a policy on food waste disposal, a pay-as-you-go system is used that pays for the collection and disposal of the amount emitted by the emitter. For this purpose, the discharge method using a food waste bag is used, but since the food waste bag must be kept indoors until the food waste bag is full, there is a problem that odors are generated in the room due to decayed and contaminated leachate of food waste. have.

In addition, during the discharge for collection, the food waste bags are damaged by the animals at night, which causes the collection by the collection companies to be left unattended. Therefore, some administrative agencies are distributing plastic waste food containers for food waste bags.

However, when a food waste collection company inflates the amount of food waste collection, and reports it to the relevant governing bodies of the county and the ward office, there is no way to inspect and confirm such collections. There is a problem that the cost for the disposal of food waste is excessively paid, and it is necessary to reduce the amount of food waste through the implementation of a pay-as-you-go system of food waste. Therefore, a food waste collection device has been developed to enable food waste to be used in a pay-as-you-go system while collecting food waste using a dedicated food waste container. However, the food waste collection device has a problem that the food is decayed in the summer, causing bad smell and maggots, and in the winter there is a problem that the food freezes in the collection box, making it difficult to process.

As a prior patent for solving such a problem, Korean Patent No. 10-1371230 relates to a control method of a food waste collection device capable of collecting food waste by a pay-as-you-go agent, and confirms the timing of equipment operation of the food waste collection device. And measure a temperature inside the food waste collection device and compare the reference temperature set according to the time point of operation of the equipment with the temperature of the food waste collection device so as to adjust the temperature inside the food waste collection device. When operating the prepared thermoelectric element module and the operation time of the equipment is confirmed to be winter, the internal temperature of the food waste collection device is compared with the reference temperature set according to the operation time of the equipment, and the internal temperature at the operation time of the equipment According to the reference temperature The thermoelectric element module is operated to heat the inside of the food waste collection device. When it is determined that the operation time of the equipment is summer, the internal temperature of the food waste collection device is compared with a reference temperature set according to the operation point of the equipment. When the internal temperature is found to be higher than the reference temperature set according to the operation time of the equipment, there is disclosed a control method of a food waste collection device for cooling the inside of the food waste collection device by operating the thermoelectric module.

4A to 4C, the food waste separation collection facility 100 having the cooling means according to the present embodiment includes a collection bin 130 containing food waste A and food waste in the collection box 130. Cooling means for cooling the power, the power supply means for supplying the power, and a separate collection chamber 110 for receiving the collection box.

The collection box 130 is composed of an outer casing 131 having a cover 132 provided at an upper end thereof, and an inner casing 139 inserted into the outer casing 131 and containing food waste.

The outer casing 131 may be formed in a rectangular cylindrical shape like the general food waste collection box 130.

The inner casing 139 may be spaced apart from the outer casing 131, and a plurality of dehydration holes 139a may be formed and may have a cylindrical shape to facilitate rotation.

Meanwhile, a rotary motor 134 for rotating the inner casing 139 is installed at the bottom of the outer casing 131. Since the inner casing is rotated by the rotary motor 134, the leachate contained in the food waste is discharged to the outer casing through the dehydration hole 139a by the centrifugal force.

Dehydration of food waste reduces water content, and the lower the cooling temperature, the greater the efficiency of decay generation and odor removal.

The lower side of the inner casing 139 is fixed to the rotary shaft 134a of the rotary motor 134, the outer peripheral surface by a plurality of guide rollers 135 installed on the inner peripheral surface of the outer casing 131 so that the rotation is smoothly made. Supported.

A discharge valve 137a for discharging the leachate B to the outside is installed at the bottom of the leachate accommodation space 137, and the rotary motor accommodation space 136 and the leachate accommodation space 137 are separated walls 138. It can illustrate what is divided by.

On the bottom of the separation collection chamber 110, a cradle 120 having a load cell 122 capable of measuring the weight of food waste is disposed, and the cradle 120 is accommodated in the leachate receiving space 137. For example, the leachate treatment space 123 for receiving and treating the leachate B may be formed.

The leachate treatment space 123 is divided into a microbial treatment tank 124 and a sterilization treatment tank 126.

The microbial treatment tank 124 is provided with a supply hole 124a for receiving the leachate B through the discharge valve 137a and a microbial supply device 126a for supplying the microbial material. The microbial agent may be any one of anaerobic or aerobic microorganisms, and is not particularly limited as long as it decomposes or removes odor components contained in the leachate (B), and any known or commercially available one can be used.

The sterilization treatment tank 126 may be provided with a spray device 126b for spraying a chlorine dioxide solution or an ultraviolet lamp.

A first connecting pipe 128 is installed between the microbial treatment tank 124 and the sterilization treatment tank 126, and a second side for discharging the leachate having completed the microbial treatment and sterilization treatment on one side of the sterilization treatment tank 126. It can be illustrated that the connecting pipe 128a is installed.

The solenoid valve 129 may be installed in the first connection pipe 128 and the second connection pipe 128a so as to be automatically opened and closed through the control unit 113.

The first connection pipe 128 serves to transfer the leachate treated first in the microbial treatment tank 124 to the sterilization treatment tank 126, and the second connection pipe 128a is secondly sterilized and purified. Discharges the leachate into the sewage pipe (C). Of course, the purified leachate must satisfy the criteria set by the Water Environment Law.

The cooling means includes a tubular evaporator 155 disposed along an inner circumferential surface of the outer casing 131, a compressor 156, a condenser 157, and an expansion valve disposed on an outer surface of the outer casing 131. 158 may be exemplified, and the configuration in which the refrigerant circulates and cools the compressor 156, the condenser 157, the expansion valve 158, and the evaporator 155 sequentially is already well known. Description is omitted.

In this embodiment, to implement the rotation and cooling of the inner casing at the same time, instead of the thermoelectric element described with reference to FIG.

When the cooling means operates, the evaporator 155 disposed inside the outer casing 131 absorbs heat, and thus the inside of the closed collection container 130 is cooled.
