Dust prevention type grinding device having screening function and used for coal chemical industry

Abstract

The invention relates to a dust prevention type grinding device having a screening function and used for the coal chemical industry. The dust prevention type grinding device comprises a main body, a pulverizing device, an operation panel and four landing legs, and further comprises a screening mechanism and two closing mechanism; each closing mechanism comprises a closing plate and two closing assemblies, and each closing assembly comprises a fixed box, a drive unit, a moving plate and two springs; and the screening mechanism comprises a collection box, a filter screen and a vibrating assembly, and the vibrating assembly comprises a first motor, a bearing, a crankshaft, a slider, a vibrating rod and two fixing rods. According to the dust prevention type grinding device having the screening function and used for the coal chemical industry, through a dust prevention mechanism, when grinding work is done, a feeding pipe can be blocked, and the condition that the surrounding air environment is affected due to the fact that pulverized coal is scattered everywhere is prevented; and through the screening mechanism, the pulverized coal can be screened to improve the pulverized coal grinding quality.

Description

technical field [0001] The invention relates to the field of coal chemical industry, in particular to a dust-proof grinding equipment with screening function for coal chemical industry. Background technique [0002] Grinding machines are widely used in chemical industry, mining, steel, thermal power, coal and other industries. The process of turning small particle materials into powder materials by external force is called crushing or grinding, or grinding for short. The machinery it uses is called a pulverizer (milling equipment). [0003] Existing pulverizers will produce a lot of dust when they grind coal. If the dust is scattered, it will pollute the surrounding air environment and reduce the environmental protection of the pulverizer. Not only that, the existing pulverizers When the mill grinds coal, it is difficult to ensure the fineness of the pulverized coal, resulting in the mixing of pulverized coal that does not meet the pulverization specifications with pulveriz...

[0003] Existing pulverizers will produce a lot of dust when they grind coal. If the dust is scattered, it will pollute the surrounding air environment and reduce the environmental protection of the pulverizer. Not only that, the existing pulverizers When the mill grinds coal, it is difficult to ensure the fineness of the pulverized coal, resulting in the mixing of pulverized coal that does not meet the pulverization specifications with coal pulverization that meets the pulverization specifications, reducing the quality of pulverized coal
