Extrusion pulverizing device for biomass particle processing and biomass pulverizing system of extrusion pulverizing device

Abstract

The invention discloses an extrusion pulverizing device for biomass particle processing. The extrusion pulverizing device comprises a shell. Supporting feet are arranged at the bottom of the shell ina left-right-symmetry manner. A feeding hopper is arranged on the top of the shell. A pulverizing base is arranged at the top end in the shell and is in a ring shape. A partition plate is arranged atthe middle portion of the shell and is obliquely arranged towards the lower right position. The position, corresponding to the position above the bottom end of the partition plate, of the right side wall of the shell is provided with a discharging port. A vertical rotation barrel is sleeved with the middle portion of the shell, vertically penetrates through the partition plate and sleeves a bearing arranged at the corresponding position of the partition plate. A vertical rotation shaft sleeves the top end of the vertical rotation barrel. The part, corresponding to the pulverizing base, of thevertical rotation shaft is provided with a pulverizing block which is of a conical shell structure, the pulverizing block is fixedly connected with the vertical rotation shaft through a connecting block, and the outer side face of the pulverizing block is provided with pulverizing teeth and grinding teeth. The extrusion pulverizing device for biomass particle processing is provided and is ingenious in structure arrangement and reasonable in arrangement, and efficient pulverizing of biomass raw materials is achieved.

Description

technical field [0001] The invention relates to the technical field of medical processing equipment, in particular to an extrusion crushing device for biomass particle processing. Background technique [0002] There are many kinds of biomass in nature, widely distributed, and the quantity is huge. According to the classification, it can be divided into several categories: trees and harvesting and processing residues, straw and agricultural residues, municipal waste, human and animal manure, and organic wastewater. Trees and harvesting and processing residues [0003] Trees and harvesting and processing residues are mainly stumps, branches, roots, leaves, etc. of various trees, as well as wood shavings, wood chips, wood chips and other forestry processing waste resources, which have abundant stocks and great potential. Firewood is the main biomass fuel. It has a long history of utilization, its calorific value is high, and the amount of combustion ash is small. my country ha...

Problems solved by technology

[0004] During the processing of biomass pellets, biomass raw materials need to be crushed and processed. Because most of the biomass raw materials are relatively hard and if the shell is inconvenient to crush, the traditional crushing equipment used for biomass pellet processing has a rigid structure and cannot achieve hard biomass.
