Problems solved by technology

[0004] The object of the present invention is a pulverized coal separator designed for the deficiencies in the prior art. It adopts a rotating blade-shaped comb filter structure to effectively capture short fibers, velvet fibers and impurities in pulverized coal. Strong, the screen is not easy to be blocked, which greatly improves the separation efficiency of coal powder. In the case of the same filtration area, the volume of the separator can be reduced, the amount of steel used can be reduced, and the manufacturing cost can be further reduced.

Abstract

The invention discloses a pulverized coal separator which is characterized in that a shell is an oblique cone, an upper cover is arranged on the top of the shell, and a discharge hole is arranged at the bottom of the shell; the upper cover is provided with a feeding hole, an air outlet and a machine seat; a comb filter device consists of a rotating bracket and filter screen plates; the plurality of filter screen plates are arranged on the rotating bracket in an inclined way in a shape of a fan blade; a driving device is fixed on the machine seat; and a rotating shaft of the rotating bracket is connected with an output shaft of the driving device. Compared with the prior art, the pulverized coal separator is simple in structure, low in manufacturing cost, strong in screening capability, hard in blockage of a screen, and can be especially used for trapping short fiber and flocked fiber in pulverized coal, so that the separation efficiency is further improved, and the service life is further prolonged.

Description

technical field [0001] The invention relates to the technical field of solid separation equipment, in particular to a pulverized coal separator for separating fibers. Background technique [0002] The pulverized coal separator is one of the most important equipment in the pulverized coal pulverization system of the thermal power plant. Wooden materials form fibers of different lengths and mix them in coal powder. The coal powder mixed with fibers directly affects the use effect, especially for stoves that use coal powder as fuel. Blocking the nozzle opening will cause the expensive nozzle to be burned out. Commonly used pulverized coal separation equipment generally adopts a grid structure, which can effectively screen out fibers, improve the purity of pulverized coal, and improve the use effect. However, the grid-structured pulverized coal separator can only screen out a small amount of short fibers and velvet fibers, which cannot completely solve the problems of nozzle o...
