Dust-containing scorched particle winnowing and separating device and method thereof

Abstract

The invention discloses a dust-containing scorched particle winnowing and separating device which comprises a barrel, and is characterized in that the barrel is formed by fixedly connecting a cylinder and a cone tube, wherein a spiral guide plate is arranged on the inner wall of the barrel; a powder outlet is formed in the top of the cylinder; a winnowing material inlet is formed in the peripheral wall of the cylinder; an upper air pipe is formed at the initial part of the spiral guide plate of the cylinder; a main air pipe is formed at the side wall on the lower part of the cone tube; a coarse material discharge pipe is arranged at the bottom of the cone tube; and an auxiliary air pipe is formed on the coarse material discharge pipe. The invention also provides a separation method. The device is reasonable in structure, high in winnowing and separating speed, high in efficiency and low in cost.

Description

technical field [0001] The invention relates to a wind separation device for solid material, which is a wind separation device for dusty coke grains and a method thereof, capable of rapidly separating graphitized coke powder and coke grains. Background technique [0002] In the production of graphite electrodes, graphitization is one of the important processes in the production of graphite electrodes. Metallurgical coke is used repeatedly as the main filling material of graphitization furnace. Due to the low strength of metallurgical coke after high temperature, about 50% of the coke particles are broken into coke powder after repeated use. A large amount of dust will be generated during the production and circulation process, which will cause serious pollution to the working environment on site. Therefore, it is necessary to separate the materials to separate the coke powder from the coke particles. [0003] Generally, screening equipment can be used to separate materials...

AI Technical Summary

Problems solved by technology

[0003] Generally, screening equipment can be used to separate materials, but it is not the best choice due to reasons such as manufacturing cost, site area, secondary dust control, and degree of damage to particle size. , secondary dust control, and the degree of damage to particle size are far superior to screening equipment. Therefore, the current wind separation technology is widely used, and the types of wind separation equipment are also constantly expanding. Wind separation technology also needs continuous development and improvement. Complete

[0004] For the particle size classification of the same material, the current air separation equipment and air separation technology are limited by the structure of the air separation separator, and the separation effect on materials with little difference in suspension speed is not ideal. The machine separates the existing metallurgical coke after graphitization, because of its low strength, the material collides with the rotating blades of the worm wheel during the rotation of the separator spindle to produce a large amount of powder, and because of its high manufacturing and operating costs, it is not suitable to be used use
