Crushing knife of crusher

Abstract

The invention provides a crushing knife of a crusher. The crushing knife comprises a rotating shaft and a plurality of blades, wherein the blades are arranged on the rotating shaft; each blade comprises a body, an upper knife body and a lower knife body; the body is connected with the rotating shaft; the upper knife body is arranged on one end, which is far away from the rotating shaft, of the side part of the body; the lower knife body is arranged on the side part of the body and positioned between the rotating shaft and the upper knife body; the connecting position of the upper knife body and the body is in smooth transition, and the connecting position of the lower knife body and the body is in the smooth transition. The crushing knife provided by the invention has the advantages of simple structure, uniformity in crushing and good crushing effect and can be used for crushing garbage and also be used for crushing biomasses.

Description

technical field [0001] The invention relates to the field of garbage crushers, in particular to a crushing knife of a crusher. Background technique [0002] Municipal waste incineration power generation will become an important way of recycling domestic waste during the 12th Five-Year Plan period. However, the waste incineration process requires crushing and refining pretreatment of waste; waste incineration boilers have requirements on the particle size of waste materials entering the boiler furnace. Higher, only uniform finely divided materials after crushing can ensure full combustion in the furnace, improve combustion thermal efficiency, ensure stable boiler load and reduce harmful gas emissions, which is conducive to the environmental protection requirements of urban life and the full utilization of resources. my country has continuously issued policies to support the development of the waste treatment industry, and local government leaders have also begun to increase t...

AI Technical Summary

Problems solved by technology

The crushing blades of the existing garbage crushers are generally large to facilitate crushing materials with relatively high hardness and low particle size requirements, but it is not easy to crush materials with high particle size requirements; while the existing biomass The crushing blades of the crusher are generally small to facilitate the crushing of materials with high particle size requirements, but the work efficiency is low, and the crushing is not very uniform, and the effect is not ideal.
