Double-regulation flow distribution type efficient separator

Abstract

The invention provides a double-regulation flow distribution type efficient separator. According to the double-regulation flow distribution type efficient separator, the pressure drop is low, the separating efficiency is high, the uniformity of outlet powder is good, and the regulation performance is good. The double-regulation flow distribution type efficient separator comprises a pulverized coal inlet, a separator shell, a separator inner cone, a distributor, radial vanes, axial vanes, a pulverized coal outlet and a feeding pipe. The pulverized coal inlet is located in the small-diameter end of the separator inner cone. The separator inner cone is installed in the separator shell. The feeding pipe is inserted in the separator inner cone. The feeding pipe is sleeved with the distributor. The distributor is in a funnel shape. Open seam structures are formed in the vertical lower section of the distributor and distributed along the circumference. Seams of the open seam structures extend in the axis direction of the distributor. The radial vanes are located at the large-diameter end of the separator inner cone and distributed along an annular belt between the inner wall of the separator inner cone and the outer wall of the distributor in the circumferential direction. The axial vanes are installed on the outer wall of the feeding pipe and located in the distributor. The pulverized coal outlet is located in the upper end of the distributor. The number of the axial vanes is larger than one.

Description

technical field [0001] The invention relates to a separator for a vertical mill, in particular to a double-adjustment split-flow high-efficiency separator. Background technique [0002] Vertical mill is an ideal large-scale grinding equipment, which is widely used in cement, electric power, metallurgy, chemical industry, non-metallic minerals and other industries. It integrates crushing, drying, grinding, grading and conveying, and has high production efficiency. It can grind block, granular and powder raw materials into required powder materials. The vertical mill is an indispensable and important equipment in the grinding industry. The vertical mill is suitable for pulverization and grinding of medium-hard materials such as bituminous coal and lean coal. It has two sets of relatively moving grinding parts. Under the action of spring force, hydraulic pressure or other external forces, the raw coal in between is squeezed and ground, and finally broken into powder; through t...

AI Technical Summary

Problems solved by technology

Due to the poor adjustment effect of the radial baffle, the separator with this static structure leads to poor powder fineness and uniformity, so that the factory often cannot meet the requirements of high-quality powder and appropriate output at the same time, which affects the economy of the factory

In order to solve the deficiencies of the separator of the static structure, there is also a dynamic separator in the prior art, which solves the defects of the separator of the static structure by adding moving parts and motors and its control system, but due to the increase of the moving parts And the motor and its control system, there are many problems in the process of use, such as increased vibration of Limao, increased energy consumption, increased pressure drop, large maintenance, etc., which seriously affect the safety of the milling system in the factory , reliability and economy

[0005] In summary, the separators used in vertical mills in the prior art have disadvantages such as low separation efficiency, high outlet powder fineness, poor powder uniformity, high pressure drop, and high energy consumption.
