BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for automatically collecting and disposing of food waste using vacuum, and is for treating and managing food waste discharged on a large scale from kitchens and restaurants in commercial facilities.

In the automatic collection facility for the disposal of food waste from commercial kitchens and restaurants in high-rise buildings, each store has a garbage inlet, so that the user can enter the above-mentioned inlet without the hassle of going down to the ground floor or the ground floor to discard the waste. It is constructed by throwing away trash.

Food waste discharged into the inlet is transferred to a food waste container placed underground in the building by interconnection with the vacuum system. This allows for environmentally friendly and effective disposal from the location where the garbage is generated to the storage area where the garbage can be removed in a reasonable way.

In the conventional food waste treatment facility, the diameters of the inlet pipe and the main transport pipe were the same, and the air intake valves opened at the time of the waste transport were installed at the ends of all the inlet pipes. Along with the vacuum pump unit, it was installed in the underground storage facility.

To this end, in the present invention, the diameter of the conventional pipe is different from the inlet pipe and the main feed pipe, so that the diameter of the inlet pipe is smaller than that of the conventional pipe. Accordingly, while the total amount of air to be sucked to form a vacuum in the tube in the vacuum pump is reduced, the vacuum in the tube can be increased in a shorter time, and a higher vacuum can be formed, thereby increasing the air transfer speed. It can be expected to increase the efficiency of food waste can be expected to increase. In addition, as the pipe diameter is reduced, the cost is reduced and economical.

In addition, according to the present invention, there is provided a bench-type inlet in accordance with the large amount of food waste generated in the restaurant, the food waste chute is divided into the inner and outer cylinders, of which the upper portion of the outer cylinder is open to the atmosphere It acts as an air intake valve when transferring garbage. In addition, it provides a cover and an emergency button for the user's safety.

While providing an inlet having the function of an air intake valve, an air intake valve provided at each end of all conventional inlet pipes was installed at the uppermost part of the granular pipe. However, at the end of the inlet pipe, an air inlet valve for the purpose of noise reduction is provided only when the length of the inlet pipe is longer than a predetermined length if necessary. Accordingly, the building effective area can be increased while the number of air intake valves installed is reduced, and the cost is reduced and economical.

In addition, in the present invention, two filter units are connected in parallel to accumulate a larger amount of vacuum. Accordingly, it is possible to increase the duration of the vacuum when using the vacuum pump of the same capacity, and as the amount of vacuum accumulation increases, the time required for accumulating the amount of vacuum required for transporting the waste is reduced until the feeder inputs the next waste. This can reduce the time required and increase the efficiency of waste transport.

Hereinafter, with reference to the accompanying drawings will be described in more detail the configuration of the food waste collection system of the automatic garbage collection facility according to the present invention.

As a large amount of air is introduced, noise may occur when the air is inhaled. In order to prevent this, the air inlet valve 2 is provided at the end of the inlet pipe A, and when the garbage is empty at the inlet 1 located at the end of the inlet pipe A, the noise is generated while being released together. Reduce

The air suction valve (2) installed in the upper part of the riser pipe of the main transport pipe (B) is increased in diameter when connected to the main transport pipe (B) from the inlet pipe (A), when the waste is transported by the increased diameter As more air is needed, it is to replenish the air volume.

In addition, according to the present invention, two filter units 6 are installed in parallel in order to accumulate a larger amount of vacuum provided in the basement of the building, and thus, the duration of the vacuum when the same capacity vacuum pump is used. As the amount of vacuum accumulation increases, the time required for the input of the next garbage can be reduced by reducing the time required to accumulate the amount of vacuum required for the transportation of waste, thereby increasing the waste transportation efficiency.
