Abstract

The invention discloses a coal grinding device for a gasifier. The coal grinding device comprises a device shell, a feeding hole, a discharging hole and a grinding mechanism, wherein the feeding holeand the discharging hole are formed in the upper and lower ends of the device shell; the grinding mechanism is further arranged in the device shell; the coal grinding device further comprises a smashing mechanism; and the smashing mechanism is positioned in the device shell, is above the grinding mechanism, and comprises a smashing plate, a smashing rotary shaft, a smashing drum and a pushing mechanism. Through arranging the smashing mechanism, the coal grinding device can further smash coal while grinding coal briquette to improve the grinding efficiency; and through arranging a vibrating mechanism, on one hand, the grinding effect can be improved, and on the other hand, the ground pulverized coal can be conveniently discharged.

Description

technical field [0001] The invention relates to the field of coal, in particular to a coal pulverizing device for a gasification furnace. Background technique [0002] Coal is one of the traditional energy sources, and it is also the raw material for making gas. When making coal gas, it is basically produced by using a gasifier. First, the coal block is ground into coal powder, and then mixed with water vapor and air for incomplete combustion reaction to obtain hydrogen and carbon monoxide. The degree of pulverized coal grinding directly affects the efficiency of pulverized coal combustion. At present, most coal pulverizing devices grind coal lumps directly, without further pulverizing coal lumps before grinding, which will lead to lower grinding efficiency. Low. Contents of the invention [0003] The object of the present invention is to provide a coal pulverizing device for a gasifier to solve the problems raised in the above-mentioned background technology. [0004] ...
