A municipal solid waste shredder

Abstract

The invention discloses a municipal domestic garbage crusher, which comprises a feed inlet, a compression chamber, a crushing chamber, a discharge port and a compression motor. A crushing blade is arranged in the crushing chamber. The compression chamber is equipped with a triangular Leroux rotor and an eccentric shaft, which can drive the compression rotor to rotate around its center, and at the same time drive the compression rotor to revolve around the center of the compression chamber, so that the three corners of the compression rotor are always close to the inner wall of the compression chamber during the rotation , and then realize the automatic control of the crusher by setting electrical components such as a microcomputer controller. Compared with the prior art, the present invention has the following advantages: the crusher can effectively avoid the stall caused by the shaft winding problem; the size of the particles can be changed by adjusting the rotating speed of the blades and the speed difference between two groups of blades; Consumption and control the size of the crushed particles; continuous feeding; reduce the pressure on the crushing knife shaft to prevent the material from jamming and stopping.

Description

technical field [0001] The invention relates to the field of garbage crushing, in particular to a municipal household garbage crusher. Background technique [0002] With the continuous acceleration of the urbanization process, the generation rate of municipal solid waste is also increasing rapidly. A large amount of garbage not only affects the quality of the social environment, but also occupies a large amount of available land, hindering the development of the city. The harmlessness, reduction and recycling of garbage disposal is an important content of urban management. Garbage crushing technology plays an important role in subsequent sorting, incineration, landfill and other aspects. The size of the crushed garbage particles is uniform, which is convenient for screening and extraction. At the same time, the specific surface area of ​​the crushed garbage particles is large, which is conducive to combustion and chemical treatment. Therefore, the crushing of urban garbage...

Problems solved by technology

On the one hand, the components of municipal solid waste are complex, and the crushing tools have different adaptability to different physical properties, resulting in uneven particle size after crushing, which brings great inconvenience to subsequent incineration and sorting; on the other hand, To obtain broken particles of different particle sizes, it is often necessary to disassemble the cutter and adjust the shape, density and spacing of the cutter, which is time-consuming and cumbersome to maintain
