Cage Rotor Eddy Current Ultrafine Powder Concentrator

Abstract

The invention discloses a cage type rotor eddy flow ultra-fine powder concentrator, which comprises a host machine rack, a feeding device, a power transmission device, a host machine housing, a volute wind intake and return device, an ultra-fine sorting device, a cyclone gas-solid separation device, a control box and other operation function components, wherein the host machine rack is welded and fixed to form the rigid integrate having the frame structure form, the feeding cylinder, the power transmission device and the eddy flow powder collection chamber are directly installed on the horizontal reference connection plate of the host machine rack so as to provide the form and position reference and the position precision for the installation connection of the operation components, and the ultra-fine powder concentrator adopts a plurality of innovative technologies such as volute bottom lateral wind intake, double layer diversion blade directional wind inducing, cover plate type wind blocking sealing ring wind blocking leakage prevention, underlying slurry type powder throwing dish throwing dispersing lifting, cage type rotor duplex ultra-fine classification, cyclone gas-solid separation and the like, and has prominent characteristics of stable eddy flow wind force, uniform particle dispersion, accurate micro-powder grading, complete gas-solid separation, and the like.

Description

technical field [0001] This patent relates to a building material mechanical equipment, specifically to a cage-type rotor eddy current ultra-fine powder separator for producing mine tailings ultra-fine powder. Background technique [0002] Mine tailings are the remaining slag after primary selection, re-selection, and selection in metal mines during the beneficiation process. It is a very important industrial solid waste. At present, most metal mines in my country adopt wet beneficiation. Mine tailings are discharged in a fluid state and are stored and managed in the form of building tailings dams; storage and management of mine tailings not only requires the acquisition and occupation of a large area of ​​land, but also invests huge sums of money in the construction of dams and daily maintenance management. After long-term storage of mine tailings dries up, some mine tailings will form tailings powder; tailings powder has physical characteristics such as fine particles, lar...

AI Technical Summary

Problems solved by technology

[0008] This patent aims at the deficiencies and weaknesses of the general powder particle sorting machine in the ultra-fine sorting operation of mine tailings grinding powder. A number of innovative technologies such as powder disc dispersion, cage rotor double classification, cyclone gas-solid separation, etc., form a cage rotor eddy current ultrafine powder separator that can separate ultrafine powder from grinding powder; solve it The existing general-purpose powder particle sorting machinery has technical problems such as large average particle size and fineness, low effective powder selection rate, wide particle size distribution range, more air leakage and collapse, low production efficiency, fast equipment wear, and high energy consumption.
