Embodiment Construction

[0008] See figure 1 , figure 2 , Coal Mill Dynamic Separator, the appearance structure of the device is that the upper cone 4, the middle cylinder 15, and the lower cone 16 are connected by flanges. 8 is connected to the rotor shaft 5, and the rotor shaft is connected to the rotor 6. The rotor 6 is composed of a rotating impeller 9 connected to a cylindrical frame 10. The frame 10 is evenly provided with partitions 11, and the rotor is arranged in the middle cylinder. The rotor frame in the middle cylinder The outer periphery is evenly provided with special-shaped adjustable blades 7 along the circumference, and the plurality of special-shaped adjustable blades are connected with the flanges at both ends of the middle cylinder body, and the axial direction and the circumference extend clockwise at an angle. The special-shaped adjustable blade 7, the rotor 6, and the inner cylinder cone of the middle cylinder form a certain movement gap; the fine powder air outlet 12 is arran...

Abstract

The present invention relates to mechanical sieving apparatus, and the apparatus consists of upper cone, middle cylinder and lower cone connected with flanges. The driving mechanism in the upper part of the apparatus has motor, planetary gear, rotor shaft and rotor comprising rotating vane wheel and connected cylinder frame. The middle cylinder has adjustable blades, and the adjustable blades, the rotor and the inner cone form certain motion interval. There are fine powder airflow outlet in the upper cone, coal powder airflow inlet in the lower cone, and inner conic barrel inside the lower cone and connected to the lower coarse powder outlet. The present invention has the advantages of raised coal powder fineness, raised coal powder yield, and lowered power consumption.

Description

technical field [0001] The invention relates to a mechanical screening equipment, which is mainly used in the coal powder preparation system in the cement production process to screen the coal powder ground by an air-swept coal mill. The product name of the invention is MDX type coal mill dynamic separator. Background technique [0002] According to the statistics of the National Bureau of Statistics, there are 4,740 cement production enterprises above designated size in the country, and each company has several production lines. Among the coal powder preparation systems of tens of thousands of production lines, almost all of them adopt backward and inefficient static crude oil production lines. powder separator. The separator has no rotor classification area, the fineness of pulverized coal cannot be controlled, the quality of pulverized coal cannot meet the requirements, the power consumption is large, the equipment is seriously worn, and the output is low.
