Urban household garbage crushing machine

Abstract

The invention discloses an urban household garbage crushing machine which comprises a material inlet, a compression cavity, a crushing cavity, a material outlet and a compression motor, wherein crushing blades are arranged in the crushing cavity and are connected with crushing motors through cutter shafts; a Relo triangular rotor and an eccentric shaft are arranged in the compression cavity, so that a compression rotor can be driven to rotate around the center of the compression rotor, and the compression rotor can be also driven to revolve around the center of the compression cavity; therefore, three corners of the compression rotor in a rotating process can be always attached to the inner wall of the compression cavity; automatic control on the crushing machine can be realized by arranging electric appliance components such as a microcomputer controller. Compared with the prior art, the urban household garbage crushing machine has the advantages that stop caused by shaft winding can be effectively avoided; sizes of particles can be changed by adjusting rotating speeds of the blades and a speed difference of the two groups of blades; the power consumption can be effectively stabilized, and the sizes of the crushed particles can be effectively controlled; pressure on the crushing cutter shafts is reduced, and stop caused by material locking is prevented.

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...

AI Technical Summary

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
