Automatic sand screening device for building material synthesis production and sand screening method thereof

Abstract

The invention relates to the technical field of building material processing, and discloses an automatic sand screening device for building material synthesis production and a sand screening method thereof. The automatic sand screening device comprises a sand screening box, wherein a cam is connected to the outer side of an output shaft; pendulum bobs are connected to the two sides of the sand screening box, U-shaped rods are connected to the lower ends of the pendulum bobs, and coils are connected to the U-shaped rods; and air injection openings are formed inside air injection devices, the lower end of a control device is connected with an air bag, and a magnetic block is connected into a moving block. The output shaft drives the cam to intermittently extrude a screening plate, a slidingrod compresses air in a sleeve to enter the air bag through a second one-way valve, the screening plate resets to impact the pendulum bobs, the pendulum bobs drive the U-shaped rods to vibrate, the coils on the U-shaped rods cut a magnetic induction line to generate current, the current forms a magnetic field through coils at the lower ends of the coils, the magnetic field pushes magnetic blocks to reciprocate in sliding grooves, the air in the air bag is sprayed out through through holes, and the structure solves the problems that a screening plate of an existing sand screening device is prone to blockage and low in working efficiency.
