Screen drum type sand screening device for building

Abstract

The invention discloses a screen drum type sand screening device for a building. The screen drum type sand screening device comprises a bottom plate; a screen drum is arranged between two supporting plates; a mounting shaft is fixed on the two sides of the screen drum separately; the drum wall of the screen drum is formed by two semicircular screens in an encircling mode; a material box is arranged at the top of the screen drum; the bottom of the material box is open and is in contact with the upper surface of the screen drum; the material box is connected with the top of the supporting platesthrough L-shaped rods; a first discharge port is formed in the top in one side, far away from a feed hopper, of the screen drum; a second discharge port is formed in one side, close to the feed hopper, of the material box; valves are mounted on the first discharge port and the second discharge port respectively; the end of the mounting shaft at one side of the screen drum is fixedly connected with the output shaft of the motor through a coupler; and the motor is installed on the supporting plates through bolts. The screen drum type sand screening device is novel in practical structure and simple in operation; by setting the screen drum, multistage screening can be realized, the production cost is low, and the occupied area is small; and meanwhile, a brush strip is arranged, so that the screen drum can be brushed, blockage of the sieve holes is avoided, and the screening efficiency is improved.
