Cotton firewood secondary shredder

Abstract

The invention provides a secondary smashing machine for cotton stalks. The secondary smashing machine comprises an upper shell, a lower shell, a feeding device, a main shaft, fan assemblies, a primary smashing mechanism and secondary smashing mechanisms. The secondary smashing mechanisms are arranged on the two sides of the primary smashing mechanism. The primary smashing mechanism is composed of a hammering knife assembly and a bottom plate stationary knife. The hammering knife assembly is distributed on the outer wall of the main shaft, the bottom plate stationery knife is installed in the middle of the surface of the inner wall of the lower shell, and the hammering knife assembly and the bottom plate stationery knife mutually interact to achieve primary smashing of materials. Each secondary smashing mechanism is composed of a hammering piece assembly and a stationery knife assembly. The hammering piece assemblies correspond to the stationery knife assemblies in position. The hammering piece assemblies are distributed on the outer wall of the main shaft in the circumferential direction, and each stationery knife assembly is composed of multiple rows of stationery knifes which are installed on the upper shell and the lower shell respectively. The hammering piece assemblies and the stationery knife assemblies mutually interact to achieve secondary smashing of the materials. Two times of smashing can be performed on the cotton chalks so that the particle size of the ground cotton stalks can meet the processing requirement for biomass briquetting forming.

Description

technical field [0001] The invention relates to the field of biomass pulverizers, in particular to a cotton wood pulverizer, especially a cotton wood secondary pulverizer. Background technique [0002] Cotton firewood pulverizer is often used in the production system of cotton firewood briquetting. Its main function is to crush the whole cotton firewood into crumbs and filamentous materials. piece. [0003] The main structure of the traditional cotton wood grinder is: there is a trough support plate under the feeding port to facilitate feeding; Hammer knives are installed on the top, and the hammer knives are arranged in a spiral line; a set of bottom plate fixed knives are installed on the lower shell of the cotton wood grinder; fan blades are installed on both sides of the main shaft of the cotton wood grinder. [0004] When working: manually put the material on the grooved pallet, because the spindle drives the hammer knife installed on it to perform high-speed rotation...

AI Technical Summary

Problems solved by technology

[0005] The material of this kind of cotton firewood grinder is crushed once, but the disadvantage is that most of the cotton firewood roots cannot be crushed due to their strong toughness.

After the cotton firewood is crushed, the particle size of the logistics is large, which cannot meet the processing requirements of the subsequent cotton firewood briquetting.
