Problems solved by technology

[0003] On the premise of not adding sorting equipment, the present invention uses the existing belt conveyor to separate the lumps and fines in the mined raw coal, and then sends them into the coal bunker, thereby solving the frequent blockage at the entrance of the coal bunker, which leads to The belt conveyor in the main shaft was out of service, damaged, and directly threatened the safety of the staff, which affected the technical problems of the raw coal output of the coal mine

Embodiment Construction

[0009] The screening device includes the tail drum 1, the transfer drum 2, the vibrating screen 3, the gangue picking belt conveyor 4, the redirecting drum 6, the chute 8. The tail drum 1 and the redirecting drum 6 and the transfer drum 2 form a belt conveyor. In the tail section of the machine, a vibrating screen 3 is installed below the transfer drum 2, a chute 8 is installed directly below the vibrating screen 3, and a gangue picking belt conveyor 4 is installed below the end. The belt formed by the tail drum 1 and the transfer drum 2 is horizontal The included angle is 7, the included angle is 8 degrees, the vibrating screen 3 and the horizontal, the included angle is 5, and the included angle is 6 degrees. The raw coal containing gangue (the lower group of coal) is discharged from the top of the transfer drum 2 into the vibrating screen 3, after the vibrating screen 3 works, the large pieces of raw coal and gangue flow into the gangue sorting belt 4, and the large pieces of g...

Abstract

The mechanical sieving apparatus is used in raw coal conveying process to separate lump coal from powdered coal to ensure the normal operation of the belt conveyer without stopping and damage. It includes one coal transporting belt conveyer, one coal gangue sorting belt conveyer, one vibrating sieve, one chute, and rollers. The present invention can raise output of raw coal.

Description

Technical field [0001] The invention relates to a mechanical sorting device, in particular to a sorting device that simultaneously completes the sorting and conveying the blocks and the coal surface in the raw coal. Background technique [0002] After the coal mine's fully mechanized mining face is officially put into production, the mined raw coal is sent to the coal bunker by the conveyor belt. However, because the raw coal contains a large amount of gangue and coal, it is often blocked at the entrance of the coal bunker during the process of conveying by the conveyor belt. This phenomenon has caused the main shaft belt conveyor to be shut down, damaged and directly threatened the lives of the staff, which greatly affected the coal output of the coal mine. In order to solve this problem, it is best to separate the lump and the end of the mined raw coal first, and then send it to the coal bunker. However, this requires the addition of separation equipment and the problem of the ...
