Pre-compression machine for crushing municipal domestic waste

Abstract

The invention discloses a pre-compression machine for crushing municipal domestic waste. The pre-compression machine for crushing the municipal domestic waste comprises a feed inlet, a compression cavity, a discharge outlet and a motor, wherein a compression rotor is arranged in the compression cavity, the compression rotor is a Reuleaux triangular rotor, and the compression cavity is in a cocoon shape. The pre-compression machine for crushing the municipal domestic waste further comprises a rotor hole, a rotor gear, a rotor shaft and a rotor shaft gear, wherein when the motor operates, the compression rotor is driven to rotate around the center of the compression rotor and revolve around the center of the compression cavity. Compared with the prior art, the pre-compression machine for crushing the municipal domestic waste has the advantages that waste is compressed through the pre-compression machine, so that a waste ball is formed, and the phenomenon that long fibrous waste is wound around a crushing tool when waste is crushed through a crushing machine in the later stage is avoided; feeding, compressing and conveying can be conducted and completed at the same time, and continuous feeding can be achieved; the Reuleaux triangular compression rotor can bear high pressure and is long in service life and high in abrasion resistance; the requirement for high-frequency crushing of the crushing machine can be met.

Description

technical field [0001] The invention relates to the field of rubbish shredding, in particular to a pre-compressor used for shredding municipal domestic rubbish. Background technique [0002] With the continuous acceleration of the urbanization process, the amount of municipal solid waste is increasing rapidly, and the growth rate is also increasing rapidly. The harmlessness, reduction and recycling of garbage disposal is an important content of urban management. Garbage shredding is an important link in the process of realizing the "three modernizations" of garbage, and the pretreatment technology of garbage shredding plays an important role in subsequent sorting, crushing, and incineration. The garbage shredding pre-compressor is the key to realize the garbage shredding pre-compression technology The performance of the main equipment directly affects the subsequent processing effect. [0003] The existing municipal solid waste crushing pre-compressor is often unable to co...

Problems solved by technology

[0003] The existing municipal solid waste crushing pre-compressor is often unable to continuously feed the crusher, or the feeding speed is slow, which cannot meet the high-frequency crushing requirements of the crusher

At the same time, the compression direction of the existing municipal solid waste crushing pre-compressor pre-compression mechanism is often on the same straight line as the cutter shaft of the crushing knife. Larger pressure will deform the cutter shaft, which is not conducive to crushing, but also affects safe production. brought hidden dangers
