Description

Food Waste Disposal Device

The present invention relates to a food waste disposal apparatus, and more particularly, to a food waste disposal apparatus capable of dewatering, crushing and deodorizing all food waste.

In general, the food waste treating apparatus includes a centrifugal dehydrator using a centrifugal force, a pulverized dehydrator, and a cutting dehydrator, and also includes a compression heater using a screw shaft and a fermentation processor using microorganisms.

Here, the centrifugal dehydrator has a drawback in that the moisture contained in the thick food debris, watermelon, melon and other skins and vegetables is hardly removed. And when foreign matters such as spoons, bottle caps, and towels enter the centrifugal dehydrator, the foreign matters are separated out of the dehydration container by centrifugal force, causing a breakdown of the apparatus along with frequent failures.

The crushing dehydrator is a device for installing a conventional crushing device below the food waste inlet, it is a device for randomly crushing the food waste and then transported to the compactor after the compression dehydration. However, the crushing dehydrator was inconvenient because the cleaning operation is inconvenient because the filter must be provided, as well as a large amount of time for cleaning the filter. In addition, the filter has a high probability of being damaged and should be replaced frequently. Also, when vinyl or cloth is put together with food waste, the filter is not only clogged and the vinyl and cloth are entangled in the grinder. . In addition, the grinding dehydrator has a problem that is unsuitable for home use because the noise is severely generated during operation.

The cutting dehydrator is a device for dewatering the food waste by cutting the food waste with a cutting blade, centrifugal dehydration or compression dehydration. When the metal such as a spoon or a bottle cap is put together with the food waste, the cutting blade is easily broken, and thus the cutting blade needs to be replaced or repaired, thereby causing inconvenience to the worker and adding extra costs. And, if the dehydration method is applied to decompress the food waste when the filter must be provided, which is a disadvantage of the crushed dehydrator. In addition, when the centrifugal dehydration method is applied, the dehydration efficiency is lowered, resulting in a waste point in which water remaining in the food waste cannot be neatly removed. And the cutting dehydrator has a problem that is unsuitable for home use because the noise is severely generated during operation.

The pressurized heater using the screw shaft is a device in which a screw shaft is installed inside the cylinder and pressurizes and discharges food waste at the same time as drying. However, the pressurized heater as described above not only causes bad smell when drying food waste, but also causes food waste to stick to the screw shaft, which is very inconvenient for cleaning. In addition, the pressurized heater has a high risk of an electric shock accident, a poor processing capacity per unit time, an excessive electric charge, and an unsuitable problem for a business or a home. Finally, the microbial fermentation processor is an extinction method using microorganisms, which not only generates a bad odor, but also results in a drop in processing capacity per unit time.

Accordingly, an object of the present invention is to provide a food waste treatment apparatus capable of crushing, dehydrating, deodorizing, and discharging only food waste, even if various foreign substances are contained therein.

It is another object of the present invention to provide a food waste treatment apparatus in which a failure does not occur even when foreign substances are introduced.

Still another object of the present invention is to provide a food waste disposal apparatus that can almost eliminate the moisture and odor of food waste.

In order to achieve the above object, the food waste processing apparatus of the present invention is installed on a circumferential surface of a shaft rotating with a predetermined driving force, and a blade for stirring / transfering the food waste, coupled to the shaft and faster than the shaft A plurality of covers assembled to a rotating shaft rotated with a plurality of covers for finely crushing the transported food debris and fixedly installed on an outer surface of a lower end of the main frame of the processing apparatus, and having a plurality of nozzles for supplying an appropriate amount of water to an upper end thereof. An outer cylinder coupled to the pipe, the inner cylinder for rotating the high speed located inside the outer cylinder for dewatering the food debris transported by the blade, installed in the inner cylinder to move the front / back while the dehydrated food waste A plate pushed to the bottom surface of the main frame, and the main frame Located at an arbitrary upper side and comprises a heater for removing moisture and odor generated from the food waste, and a condenser and a driving fan to condense hot air from the heater to produce condensed water.

In the figure, the food waste treatment apparatus has a heater 16 and a condenser 20, one side of the heater 20 is connected to the main frame 10 through a pipeline. At this time, the heater 20 serves to convert the moisture contained in the food waste (referring to the moisture in which odor is contained) into supersaturated water vapor at high temperature heat. The other side of the heater 20 is connected to the condenser 20 by a pipeline, and the condenser 20 condenses the water vapor supersaturated by the heater 20. That is, one side of the condenser 20 is provided with a driving fan 22 that rotates by the driving force of the motor 24, wherein the supersaturated water vapor passing through the condenser 20 by the wind generated by the driving fan 22 is condensed inside the condenser The steam, which has been converted to a slightly lower temperature, is introduced back into the main frame 10 by the fan 18. The condensate here is fed to the condensate can 46 via a pipeline. And a water pump 44 is installed on the upper side of the condensation bucket 46, the water pump 44 supplies the condensed water to the pipe 106 with a predetermined driving force, wherein the condensed water is injected by the nozzle, so that the hole 104 of the inner cylinder to the food waste To prevent blockages. In addition, the condensation can 46 is connected to the sewage canister 58 as a pipeline for overflow, where the condensate can overflow the condensate and the water discharged from the food waste discharged through the drain pipes 64 and 68. Here, a drain container 66 is installed at the lower end of the main frame 10, and a drain pipe 68 is formed at one lower surface of the drain container 66 and connected to the sewage container 58 by a pipeline. At this time, the pipeline is provided with a one-way valve 60, which prevents backflow of sewage (moisture, condensate, etc.). In addition, a plurality of drain holes 70 are formed on the right bottom surface of the main frame 10 in which the drain container 66 is installed (based on FIG. 1), and the waste water (moisture) of food waste falls into the drain container 66 through the drain holes 70.

Hereinafter, the process of crushing, dehydrating, deodorizing, and discharging food waste using the food waste processing apparatus of the present invention configured as described above will be described in detail with reference to FIG. 1.

First, as shown in FIG. 1, after the lid 12 is opened, all food wastes containing various foreign matters are supplied into the main frame 10, and then the switch installed in the control box 14 is operated. The heater 16, condenser 20 and motors 26, 32, 38 and 48 are then driven sequentially. The driving force of the motor 32 is then transmitted to the chain gear 34a and then to the chain gear 34b by the chain 36. Next, the shaft 200 rotates counterclockwise by the rotational force of the chain gear 34b. Accordingly, the blade 200 pushes toward the cutting device 600 while stirring food waste and floats upward while falling upward. Of course, the food dregs that are lifted up by the blades are crushed by the cutters of the cutting device that rotate at high speed. Then, according to the pushing operation of the blade 200, the food waste is supplied by being pushed into the inner cylinder 102 which is rotating at a high speed. That is, the driving force of the motor 38 is transmitted in the order of the pulley 40a → V-belt 42 → pulley 40b → extension 102a of the inner cylinder. Accordingly, the inner cylinder 102 rotates at a high speed to dehydrate the food waste that is beginning to be crushed, and water generated in the dehydration process falls into the drain pipe 64 through the hole 104. The water of the food waste then flows into the sump 58 via a drain pipe 64. At this time, the inner cylinder 102 is intermittently sprayed through the nozzle 108 of the pipe. That is, the condensed water stored in the condensation bottle 46 is supplied into the pipe 106 at high pressure by the driving force of the water pump 44, and the condensed water supplied to the pipe 106 is sprayed on the outer surface of the inner cylinder 102 by the nozzle 108. The jetted condensate then separates the food debris that was blocking the hole 104 from the fall or the hole. Then, the hole 104 of the inner cylinder can drain without clogging and keep clean at all times.

Afterwards, when the water content of the food waste introduced into the inner container is removed to some extent, the pinion 50 is rotated clockwise by the driving force of the motor 48, and at the same time the rack 52 is slidably moved in the front direction (left direction in FIG. 7). . Then, the plate 116 integrally installed on the shaft 114 is moved in the front direction, so that the dehydrated food waste introduced into the inner cylinder 102 is pushed out of the inner cylinder and continues to be crushed without being dehydrated. It is mixed and spread by the blades, falling, and then crushed by the cutters. At the same time, the plate 116 is moved to the right (first position) by the reverse operation of the rack 52 and the pinion 50. That is, the pinion 50 is rotated counterclockwise by the driving force of the motor 48, and at the same time the rack 52 is moved to the right (in Fig. 7) to move the plate 116 in the rear direction.

The driving force of the motor 26 is transmitted in the order of the pulley 28a → the V-belt 30 → the pulley 28b → the rotating shaft 206, and the rotating shaft 206 receives the driving force to rotate the cutter 212. At this time, the rotating shaft 206 is always rotated at a faster speed than the shaft 200. Subsequently, the food waste spread up by the blade 220 is crushed by the rotating cutter 212 while being spread out by centrifugal force and falls down again. Subsequently, the crushed food waste is supplied to the inner cylinder 102 again by the pushing action of the blade 220, and the inner cylinder 102 repeatedly performs the above-described operation. After some time, the food waste is crushed into fine particles, and the water remaining in the food waste is neatly removed.

Herein, when the food waste is crushed and dehydrated inside the main frame 10, moisture including a bad odor is generated, and the moisture is supplied to the heater 16 through a pipeline. The heater 16 then generates high heat to convert the moisture into supersaturated water vapor, which is supplied to the condenser 20 via a pipeline. At the same time, the driving fan 22 generates cold wind by the driving force of the motor 24, and the submerged water passing through the condenser 20 by the cold wind is converted into condensed water and flows into the condensation tank 46. At this time, the condensed water stored in the condensation bottle 46 is intermittently supplied to the pipe 106 by the driving force of the water pump 44. Herein, the air passing through the condenser 20 (refers to the air whose temperature has been lowered by losing heat) is introduced into the main frame 10 again by the rotational force of the fan 18. Fan 18 continues to circulate hot air in the mainframe. Thereafter, the circulation process as described above is repeatedly performed, whereby water and odor remaining in the food waste are gradually removed.

Thereafter, the operation as described above is repeatedly and repeatedly performed, whereby the food waste inside the main frame 10 is finely pulverized, and at the same time, only the food residues are completely dehydrated and moisture and odors are almost removed. Then, when the food waste treatment (grinding and dehydration) process is finished, the motor 72 installed in the front of the main frame 10 generates a predetermined driving force, the rack gear 74 operates the discharge door 76 by the driving force. At the same time, the motor 32 generates a driving force in the reverse direction, whereby the shaft 200 rotates clockwise by the driving force. Then, the blade 220 transfers the food waste to the discharge door 76 by the rotational force of the shaft 200, and then the transferred food waste is discharged to the outside through the discharge door 76. Thus, the crushing, dehydration and deodorization process of food waste is completed.

As described above, the present invention, in all food wastes containing various foreign matters (spoons, chopsticks, bottle caps, towels, etc.) not only finely crush the food waste except the foreign matters but also the moisture remaining in the food wastes Can be removed almost completely. In addition, compared to the conventional food waste treatment apparatus, the grinding, dehydration, deodorization and processing capacity per unit weight per hour are excellent, and there is an advantage in that it is possible to remove the odor and moisture generated in the food waste in a short time using a heater. In addition, when the inner cylinder of the dehydration apparatus is cleaned, no separate water is required, and the nozzle can be regularly cleaned through the nozzle without disassembling the inner cylinder, and heat can be recovered and used to reduce energy waste as much as possible. In addition, the dehydration device and the cutting device of the present invention is a very robust and stable structure that is discharged to the outside with the finished food waste without the case that the parts are broken or tangled in the parts even if the foreign matter is put into operation or malfunction or stop working The durability of the device is so excellent that it can not be compared with the conventional device.
