The present invention relates to a food waste sorting crusher, and more particularly, it is possible to simultaneously perform the foreign matter sorting and crushing process without a transfer device and an intermediate storage tank to prevent the generation of dust and odor generated during garbage processing and high efficiency It relates to food waste sorting crusher.

In general, in the cities where people live, a huge amount of garbage and waste are growing exponentially each year, and only the food waste that is decomposed by bacteria among these urban wastes is selected and buried underground for disposal or incineration. Although there are very few, most of them are using food shredder, waste paper, wood chips, rags, plastics, glass, and metal scraps to break them into small particles using a crusher to bury them away from the city or burn them.

Such a shredder has a supply port and an outlet port, and rotatably supports a cylindrical screen having protrusions on the circumferential surface, rotatably supports a main shaft having a crushing plate inside the cylindrical screen, and the outer circumference of the crushing plate is smaller than the protrusion inner circumference. It is selected as a dimension and has a space in relative rotation, and consists of a drive device for rotating the cylindrical screen and the main shaft by the same motor.

When the conventional waste crusher is supplied with urban waste into the supply port, the main shaft is rotated in the cylindrical screen into which the waste is injected, and a plurality of crushing plates formed on the main shaft crush the urban waste with a large rotational force. Between the tip and the tip of the shredding plate is smaller and discharged to the outlet.

However, these conventional shredders are relatively large and have no sorting function during the shredding of urban waste, preventing dust or dust from being scattered, and during the shredding, food waste cannot be sorted with metal, glass, etc. As a cause, the life of the shredder was shortened, and after the urban waste was shredded, the urban waste had to be transferred to a transfer device and stored in an intermediate storage tank, which caused high production costs and difficulty in manufacturing.

In addition, the conventional shredders such as food waste containing the weight components such as moisture in the city waste sinks to the bottom, and the performance of the shredder is drastically reduced, so that only the semi-dry waste of the city waste can be disposed of, and such as food waste Wet garbage has a problem that can not be disposed of.

The present invention is to solve the above problems, it is possible to perform the foreign matter screening and shredding process at the same time without the transfer device and the intermediate storage tank hygienic and efficient food waste to prevent the generation of powder and odor generated during garbage processing The purpose is to provide a screening crusher.

In order to achieve the above object, the present invention is an input hopper which is opened to the top and the waste is injected; A pressure screw for forcibly transporting the waste which is formed at the bottom of the feeding hopper; A motor extending the main shaft of the pressure screw to rotate the main shaft at one end thereof; A fixed cylinder which is fixedly formed between the motor and the screw feed screw, the fixed blade having a plurality of fixed blades at the top thereof, and a plurality of perforated networks formed at the bottom thereof, and having a plurality of crushing plates protruding from the main shaft to the inner circumference; It is characterized in that it has a foreign material discharge hole formed in the main cylinder rotational direction side of the fixed cylinder and a discharge transport means located in the lower portion of the fixed cylinder and compresses the waste particles flowing through the other hole network to discharge to the outside through the discharge port.
