Circular motion vibrating screen

Abstract

The invention discloses a circular motion vibrating screen and belongs to the technical field of mechanical device designs. The circular motion vibrating screen comprises a screen box, supporting feet, bearing seats, couplers, motors, screen holes and excitation shafts. The screen box is supported by the four supporting feet. The bearing seats are arranged on the front and rear side walls of the screen box. The excitation shafts are mounted in holes of the bearing seats. The front ends of the excitation shafts are connected with the motors through the couplers. The bottom of the screen box is a mesh structure full of the screen holes. The motors are started, the excitation shafts rotate following the motors, the excitation shafts emit vibration of certain amplitude, and finer particles in a product located on the screen holes are leaked down from the screen holes to achieve the purpose of product screening. According to the circular motion vibrating screen disclosed by the invention, device supporting is reliable, turnover is not liable to occur, equipment working is stable, the particles left on the screen holes easily flow from the right side of the bottom face of the screen box, and amplitude adjustment of the excitation shafts is convenient.

Description

technical field [0001] The invention relates to the technical field of mechanical device design, in particular to a circular motion vibrating screen. Background technique [0002] The vibrating screen works by using the reciprocating rotary vibration generated by the vibration of the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce plane circular vibration, while the lower rotating weight causes the screen surface to produce conical rotary vibration. The effect is to make the screen surface produce double-rotating vibration, and its vibration track is a complex spatial curve. The curve is projected as a circle on the horizontal plane, while the projection on the vertical plane is an ellipse. The exciting force of the hammer can change the amplitude, and adjusting the space phase angle of the upper and lower weights can change the curve shape of the motion track of the screen surface and change the motion track of the material on the sc...
