Domestic garbage screening device

Abstract

The invention discloses a domestic garbage screening device which comprises a rack. A feeding chute is formed in one end of the rack. A plurality of sets of screening units are arranged in the rack. Each set of screening unit is connected with a set of power unit. Each set of power unit comprises a motor and a transmission mechanism. Each set of screening unit comprises a driving roller and a driven roller, wherein one end of the driving roller is connected with the corresponding motor, and the other end of the driving roller is connected with the corresponding transmission mechanism. Each transmission mechanism is connected with the corresponding driven roller. Each of the driving rollers and the driven rollers is provided with a plurality of discs. The discs on each driving roller and the discs on the corresponding driven roller are arranged in a staggered manner. When domestic garbage is screened, cloth strip type soft and long materials in the domestic garbage can be effectively prevented from being twined, in addition, the domestic garbage is screened while being conveyed, and the separation efficiency is improved. The maintaining cost can be reduced, energy consumption is reduced, in addition, the structure is compact, dust emission can be reduced, and environment pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a household garbage screening equipment. Background technique [0002] The existing domestic waste pre-sorting usually adopts a drum screen machine. The material particles are picked up by the circular motion of the screen cylinder, and then rolled down to the upward moving particles, which makes the material mixing very insufficient, and it is not easy to make the fine particles in the middle The material moves to the edge and touches the screen, and due to the centrifugal force, the material slides along the circumference of the screen cylinder or adheres to the cylinder wall and is not easy to fall, so the screening efficiency is low and the classification levels are few. The existing screening equipment is not compact in structure and has relatively high requirements for installation and handling. A large amount of dust is generated when materials are sieved. In th...

AI Technical Summary

Problems solved by technology

A large amount of dust is generated when the material is screened. In this link, because the material contains dust, it will cause great harm to the environment and the body of the operator.

This kind of equipment not only has high maintenance cost and energy consumption, but also has low sorting efficiency, and is also limited by the space of the site.

In addition, soft or long materials such as cloth strips in domestic waste are easy to hang on the screen holes, causing blockage and making cleaning more difficult
