Description

Food waste disintegration apparatus {APPARATUS FOR DISPOSING FOODWASTE}

The present invention relates to a food waste decomposing apparatus, and more particularly, to effectively disintegrate food waste generated in homes, restaurants, restaurants, etc. in a relatively simple configuration, and is installed in a lower portion of a sink by a pulverizing apparatus. The present invention relates to a food waste decomposing and treating device that disintegrates food wastes by disintegrating by a microorganism in a mechanical method and at the same time repeatedly disintegrates them into a liquid phase.

In general, food wastes generated at home or restaurants are collected and disposed of through composting or feed process or incineration.In order to perform such a process, processing such as collection, storage, and transportation of food waste must be preceded. In this way, the disposal of food waste is very difficult and cumbersome, and it takes a lot of processing costs. Therefore, it is not effective or economical to handle food waste in this way. There is a problem that causes serious air pollution.

Accordingly, a food crushing device is installed at the lower portion of the kitchen sink to crush the food waste and then discharged to the outside through a drain pipe. However, the food crushing device is a food waste crushed by a grinding blade rotated by a motor. Since it is to be discharged as it is, it is not possible to reduce the amount of waste, there was a problem causing water pollution.

In order to solve this problem, after crushing the food waste, as a technology for improving the treatment effect of food waste by adding microorganisms, Republic of Korea Utility Model Publication No. 20-0338258 and Patent Publication No. 10- A food waste treatment apparatus using microorganisms of 2005-0036834 has been proposed. Such a technique can be expected to decompose and discharge food waste to some extent using microorganisms, but it is very difficult to install in a limited space under the sink.

Accordingly, the inventors of the present invention, as shown in the Republic of Korea Utility Model Registration No. 20-0410491 and the housing is formed with a first space and a second space connected to the sink drain, the grinding blade is installed on the first space, An electric motor for rotating the grinding blade, a discharge pipe through which the crushed food waste is discharged, a case coupled to the outer circumference of the housing to form a microbial accommodating space, and spraying microorganisms in the microbial accommodating space into the first space; A "sink substitute food waste grinder" having a microbial supply unit composed of a pump and a controller is proposed. According to such a "sink bin food waste crushing device", it can be easily installed in the lower sink, it can be expected to effect the effective decomposition of food waste in the discharge process by inserting microorganisms during the crushing of food waste. However, there is a problem that the pulverizing device according to such a technique is discharged through the discharge pipe in the state that the crushed food is not completely processed.

On the other hand, the "kitchen waste treatment apparatus" of the Republic of Korea Patent Publication No. 10-2002-0002186 has been proposed as a technology that can solve the above problems. The kitchen waste treatment apparatus includes a disposer for crushing incoming food waste connected to a drain hole of a sink, a disintegrator unit installed through a connection pipe and a conversion valve to the disposer, and a discharge liquid from the disintegrator unit. A discharge pipe for discharging and a gas discharge part for discharging the gas in the decomposer part, wherein the connection pipe is connected to the discharge pipe through the conversion valve and the conversion valve is operated only when the disposer is driven. The discharge liquid discharged from the feeder is supplied to the decomposing unit, and is operated to be discharged directly to the discharge pipe when the disposer is not driven. In addition, the decomposition apparatus unit is provided with a group of cultivation material to be a colony of microorganisms, a rotating drum which maintains the group of the cultivating material and discharges other than crushed kitchen waste, and a housing which keeps the rotating drum in a sealed state.

According to the kitchen waste treatment device configured as described above, the food waste is crushed by the disposer and decomposed by the microorganism in the decomposer to prevent environmental pollution and to clean the food waste cleanly. Since the made food waste is not easily crushed by a crusher such as a disposer, the food waste cannot be completely processed due to the remaining fibers, or the decomposition time by the microorganism takes a long time, thereby reducing the treatment efficiency.

In the kitchen waste treatment apparatus as described above, since the decomposition process of food waste by microorganisms is performed only inside the rotating drum, it takes a long time to complete the decomposition, and accordingly, the maintenance cost increases because the motor must be driven for a long time. There was a problem. In addition, since the decomposition unit cannot maintain a temperature at which the microorganisms are easy to breed, the treatment efficiency is lowered, and there is a problem in that the microorganisms cannot be used at all in winter. The internal cleaning or maintenance of the rotating drum is difficult, and thus there was a problem that stable treatment and hygienic treatment of food waste was impossible.

Therefore, the present invention is proposed to solve the problems of the prior art, it is possible to effectively decompose the food waste generated in homes, restaurants, restaurants, etc., it is configured in a simple concise structure to be installed under the sink At the same time, it disintegrates food waste in a mechanical way and at the same time repeatedly disintegrates it into a liquid phase to dissipate it into a liquid phase, which shortens the decomposition time of food waste, improves processing efficiency, and removes food waste without a separate purification facility. An object of the present invention is to provide a new type of food waste decomposition treatment apparatus that can be environmentally friendly.

In particular, it is an object of the present invention to provide a new type of food waste decomposition treatment apparatus that can be formed in an easy-to-separable structure to be able to conveniently perform washing and cleaning operations to improve hygiene and convenience in use. do.

When the separation is removed, the drum 220 is free, and in this state, the drum 220 may be removed to wash or perform maintenance.

Meanwhile, the screen 230 mechanically cuts, rubs and compresses the food waste together with the drum 220. The screen 230 is disposed below the drum 220 in the housing 210, and has an outer circumferential surface of the drum 220. Spaced apart to be installed in the form surrounding the lower periphery of the drum 220, a second distribution hole 232 of a diameter smaller than the diameter of the first distribution hole 222 of the drum 220 is formed. The screen 230 is formed by bending and forming a hemispherical shape in a state in which a plurality of second flow holes 232 are perforated at regular intervals on a flat plate having a rectangular plate shape, and the second flow holes 232 are approximately Finely processed food waste is passed through downward to have a diameter of 1 mm or less. In addition, according to the present exemplary embodiment, a plurality of brushes 228 are protruded in the longitudinal direction on the outer circumferential surface of the drum 220 to brush the second flow hole 232 of the lower screen 230 during the rotation operation. This will remove the foreign matter. Such a brush 228 is made of a metal material, in addition to the brushing action of the screen 230 has a function of cutting food waste when the volume of food waste is large.

On the other hand, the screen 230 is mounted on the support plate 212 formed on the lower housing 210. The support plate 212 is located in the housing 210 under the screen 230 and is installed to support the screen 230, so that food waste falling through the screen 230 is lower than the screen 230.

On the other hand, in the present embodiment, as shown in Figure 4, the lower side of the screen 230 and the drum 220 is installed to be located at a constant depth into the settling tank 240 is a constant depth in the treated water accommodated in the settling tank 240 To be locked. By such a configuration, moisture is always applied to the food waste processed in the drum 220 so that the decomposition by the microorganisms is effectively performed, and the food waste between the drum 220 and the screen 230 is effectively in a soft state. Allow to be refined by compression, friction and cutting.

On the other hand, although not shown in the figure, the food waste decomposition processing apparatus 200 according to the present embodiment is installed on the upper side of the drum 220, the water supply apparatus including a nozzle for spraying water in accordance with a predetermined time or internal temperature ( 290, see FIG. 1) to prevent the temperature rise during the decomposition process by the microorganism and to suppress the occurrence of odor. In this regard, a small amount of gas is generated in the housing 210 when the food waste is processed by the microorganism. For this purpose, a fan or the like may be installed in the housing 210 to allow the internal gas to be discharged to the outside.

Again, referring to FIGS. 2 to 4, when the food waste is processed by the food waste decomposition processing apparatus 200 according to the present invention, the food waste is in the housing 210 (the exact position at this time is the drum 220). ), The liquid component drops through the drum 220 and the screen 230 toward the lower settling tank 240, and is smaller than the diameter of the first distribution hole 222 of the introduced food waste. Solid content having a size is introduced into the drum 220 through the first distribution hole 222. The small particles of food waste that pass through the first flow hole 222 but fail to pass through the second flow hole 232 remain between the drum 220 and the screen 224, and the drum 220 and the screen 224. ) Is refined by compression and friction. In this case, food waste having a long length such as food waste or fiber placed between the drum 220 and the screen 230 is effectively cut by the shear force generated by the rotation of the drum 220.

While being introduced into or out of the drum 220, the granularity is compressed, cut, and rubbed, and is destroyed by the microorganisms contained in the microorganism complex 260 and treated as fine particles. The food waste of the fine particles treated with the liquid treatment formed by such a treatment process or fine particles having a predetermined size or less (fine particles having a size of 0.8 mm or less smaller than the diameter of the second flow hole 232 in this embodiment) is It is dropped to the settling tank 240 through the second distribution hole (232).

As such, the food waste of the liquid treatment material or the fine particles introduced into the settling tank 240 is decomposed and extinguished again by the microorganisms contained in the microorganism complex 260 accommodated inside the settling tank 240, and the settling tank 240 is Decomposition of the microorganisms by the heating means 280 has the optimum temperature conditions, so the rapid and active decomposition is carried out, the supernatant is decomposed in the sedimentation tank 240 and finally the liquid treatment is discharged through the outlet 242 Overflowed and discharged to the outside.

On the other hand, foreign matter such as by-products, plastics, iron, fibers, etc., which are not completely extinguished in the process of disassembling food waste by the drum 220 and the screen 230, remain on the screen 230. Foreign material can be removed by opening the door device 214, and then treated through a predetermined treatment method. In addition, since the screen 230 is washed by the brush 228 formed on the outer circumferential surface of the drum 220, the second distribution hole 232 is prevented from being blocked by the mucus generated during the decomposition by food waste or microorganisms. In addition, since the drive shaft 252 for driving the drum 220 can be easily separated from the motor 254, the drum 220 can be separated and washed in a state where the drive shaft 252 is removed by a simple detachment operation. It is possible to maintain clean hygiene and operation.

Again, referring to FIG. 10, when the sink waste treatment system is constructed using the food waste decomposition treatment apparatus 200 according to the present invention, the food waste decomposition treatment apparatus 200 is crushed through a connecting pipe 217. It is connected to the 100 so that the food waste crushed in the crusher 100 is introduced. In this case, when general water is discharged from the sink 1 in addition to the food waste if necessary, the bypass pipe may be configured to be discharged directly to the discharge pipe 216 without passing through the food waste decomposition apparatus 200. In addition, the discharge port 242 of the food waste decomposition processing apparatus 200 according to the present invention is connected to the discharge pipe 216 is configured.

As described above, the food waste decomposition treatment apparatus according to the preferred embodiment of the present invention has been shown in accordance with the above description and drawings, but this is only an example and various changes without departing from the technical spirit of the present invention. And those skilled in the art will appreciate.

The food waste decomposition treatment apparatus according to the present invention can effectively decompose food waste generated in homes, restaurants, restaurants, and the like. In addition, since it is configured to be used without using the destructive material that needs to be constantly exchanged, and can be configured relatively small, it is possible to reduce the installation space is particularly easy to install inside the sink. Therefore, it can take the form used alone in a sink, and can be installed and used in connection with a grinder already installed.
