Embodiment Construction

[0017] see figure 1 and figure 2 , which shows a schematic diagram of the appearance structure of an embodiment of the equipment for directly making pulverized coal into balls proposed by the present invention. The equipment includes a pulverized coal belt conveyor 1, a first pair of rollers 2, a sheet coal belt conveyor 3, a pulverizer 4, a coal particle belt conveyor 5 and a second pair of rollers 6.

[0018] The first pair of rollers machine 2 is the equipment that is used to extrude pulverized coal to make it into sheet coal, and it comprises motor 21 and two cylindrical pair of rollers 22 with smooth surface, and is installed between motor 21 and two pair of rollers 22 Between the coupler 23, the motor 21 drives the coupler 23 to act, and the two output ends of the coupler 23 respectively drive the two pairs of rollers 22 to rotate in opposite directions (counter-rotation) to each other, so that the The pulverized coal forms flake briquettes. The second pair of ...

Abstract

The invention relates to equipment for directly fabricating coal balls from pulverized coal, which comprises a first roller machine, a grinder and a second roller machine, wherein the first roller machine is used for directly compressing pulverized coal into sheet type coal, the grinder is used for receiving the sheet type coal and fabricating the sheet type coal into block-shaped coal, and the second roller machine is used for receiving the block-shaped coal and compressing the block-shaped coal into coal balls, a plurality of concave parts are arranged on the outer periphery of each roller in the second roller machine, and the concave parts on each two rollers are opposite. According to the equipment, pulverized coal with low water content is directly fabricated into coal balls, binding agent is not needed for addition, on one hand, the cost on fabricating coal balls can be saved, and on the other hand, plenty of coal resources can be saved by using the coal balls for coking.

Description

technical field [0001] The invention relates to a device for directly making coal powder into molded coal and a production method thereof, and is especially suitable for making coal powder from fine coal powder screened out from coking coal into molded coal and a production method thereof. Background technique [0002] Coking coal mainly uses the four major coal types of gas, fertilizer, coke and lean coal. Since the moisture content of coking coal before furnace loading should not be less than 8% in theory, it is generally controlled at more than 10%, especially after pulverization by a pulverizer, there are a large amount of finely pulverized coal dust in the coal material. When the water content is greater than 8%, most of them adhere to other coal particles and exist in an aggregated state. When the moisture content of the furnace coal is lower than 8%, the temperature of the coal material rises sharply from normal temperature by several hundred degrees at the moment of...
