Embodiment Construction

[0014] Such as figure 1 and 2 As shown, the crushing knife of the crusher includes a rotating shaft 1 and several blades 2 arranged on the rotating shaft. The lower cutter body 23 located between the rotating shaft 1 and the upper cutter body 22 on the side of the body 21 has a smooth transition at the connection between the upper cutter body 22 and the body 21 , and a smooth transition at the connection between the lower cutter body 23 and the body 21 . The body 21 is welded on the rotating shaft 1 . The body 21 gradually narrows from an end away from the rotating shaft 1 to an end connected to the rotating shaft 1 . The above-mentioned several blades are helically distributed on the rotating shaft 1 along the axial direction of the rotating shaft 1 , preferably helically evenly distributed on the rotating shaft 1 . The number of blades is preferably 13. When several blades are helically distributed on the rotating shaft 1, among two adjacent blades, the center of the ver...

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...
