The utility model discloses a coal water slurry filtering sieve which comprises a machine frame. A rotating shaft is erected on the machine frame. The rotating shaft is connected with a supporting rod. The tail end of the supporting rod is connected with a sieve plate to form a cylindrical screen. The top of a support is connected with a gas pipe through two connecting rods. The gas pipe is connected with a gas pump. A gas hole is formed in the gas pipe. The gas hole is formed downwards. When the sieve plate on the screen is blocked, the rotating shaft drives the screen to rotate. When the sieve plate passes through the gas pipe, high-pressure gas in the gas pipe is sprayed out to be blown to the sieve plate, particles which block the sieve plate are blown out and fall down, the particles rotate gradually to an outlet during a screen rotating process, and accordingly clearing of the screen is completed. Flushing is of no need, resources are saved, and abrasion on the screen is lowered.
