Coal slurry sieving equipment

The invention discloses coal slurry sieving equipment. A motor is connected to a sieve drum through a transmission shaft; the left side of the outer surface of the sieve drum is not provided with a sieve pore; the rest positions of the outer surface of the sieve drum are uniformly distributed with sieve pores; the sieve drum and the center shaft of a fine-particle coal slurry collecting barrel are on the same straight line; the fine-particle coal slurry collecting barrel sleeves the outer part of the sieve drum; the left side of the fine-particle coal slurry collecting barrel extends out of the sieve drum; the left side of the fine-particle coal slurry collecting barrel is provided with an anti-leakage plate; the left side of the anti-leakage plate is provided with a sealing ring; the bottom of the fine-particle coal slurry collecting barrel is provided with a fine-particle coal slurry outlet; a slurry inlet and a coarse-particle coal slurry outlet are formed in the cylindrical side plate at the left side of the sieve drum; and a valve is separately arranged on the slurry inlet, the coarse-particle coal slurry outlet and the fine-particle coal slurry outlet.
