And a rotating screen for the centrifuge of the automatic garbage collection system.

Recently, apartments, officetels, commercial complexes, residential complexes or complex complexes that are newly constructed are equipped with an automatic garbage collection system. The automatic garbage collection system is a system for embedding a transport line from an input or indoor common input port for each generation to a garbage dump, and transferring the waste inputted from the input ports to the garbage dump by a vacuum suction force formed in the transport pipe.

1 shows an example of a conventional conventional automatic garbage collection system proposed in Republic of Korea Patent No. 10-1044854. The automatic garbage collection system as shown in FIG. 1 separates the general waste and food waste into the collection pipe inside the building so that the food waste and the general waste do not mix, and the pipeline at the end of the transfer pipe leading the waste to the treatment facility. In the food waste discharging period, the end of the conveying pipe is connected to the food separator, and the end of the conveying conduit is connected to the centrifugal separator during the food waste discharging time. It is configured to collect the returning pig after the end of the communication to the pig receiver in communication.

In the centrifugal separator 14 in which the general waste is collected, the introduced general waste is discharged to the lower portion of the cyclone-shaped wall surface, and the smell is discharged to the outside through the discharge passage provided at the upper portion.

At this time, the upper portion of the centrifuge, the rotary screen is rotated by a motor to prevent the foreign matter light weight, such as vinyl contained in the general waste to drift with the discharge air to escape to the outside.

The rotating screen includes a bracket that rotates through a rotational force transmitted from a motor, and a mesh drum disposed in a cylindrical shape at a lower portion of the bracket to absorb contaminated air and prevent foreign substances larger than a predetermined size from passing through. It is done by

However, the rotating screen has a problem that the drift vinyl, paper, etc. are interposed in the mesh drum to close a part of the mesh drum, and the intervening vinyl is introduced into the mesh drum by the wind pressure of the exhaust air. In addition, the vinyl passed through the mesh drum is re-opened in the filter provided in the discharge passage, and the performance of the filter is reduced, and at the same time, the capacity of the filter is blocked by the vinyl, there is a problem that the processing capacity is lowered.

The present invention is to solve the above problems, the foreign matter light weight such as vinyl, paper interposed in the hole of the mesh screen of the rotating screen by spraying high pressure compressed air to separate from the hole of the mesh network, the motor is It is an object of the present invention to provide a rotating screen for a centrifuge of an automatic garbage collection system capable of removing foreign matters interposed in the holes of the mesh network by rotating the mesh network even while the food waste is being stopped.
