Self-synchronizing translation elliptical vibrating screen with three shock excitation motors

Abstract

The invention discloses a self-synchronizing translation elliptical vibrating screen with three shock excitation motors. The self-synchronizing translation elliptical vibrating screen with the three shock excitation motors consists of a feeding hopper, a first shock excitation motor, a second shock excitation motor, a third shock excitation motor, a screen box, an isolation spring and a base, wherein the axis of the second shock excitation motor is parallel to that of the third shock excitation motor; the eccentric mass moment of the second shock excitation motor is the same with that of the third shock excitation motor; the second shock excitation motor and the third shock excitation motor rotate oppositely at equal speed; a perpendicular bisector of a connecting line of the axle center of the second shock excitation motor and the axle center of the third shock excitation motor is deviated from the total mass center of the screen box by a certain distance; the mass center of the screen box moves linearly and the screen box swings around the mass center by using generated linear shock excitation force; the axis of the first shock excitation motor is parallel to the axis of the second shock excitation motor and the axis of the third shock excitation motor; and by using shock excitation force generated by the first shock excitation motor, the mass center of the screen box moves circularly, and the screen box swings around the mass center. By exactly designing mounting positions of the three shock excitation motors, translation elliptical movement of the screen box is realized. By using the self-synchronizing translation elliptical vibrating screen, large shock excitation force can be provided, and the motor mounting positions are not limited by the structure of the screen box during design. The self-synchronizing translation elliptical vibrating screen is simple in structure, easy to manufacture and mount, easy and convenient to maintain, low in noise and low in cost.

Description

technical field [0001] The invention relates to a self-synchronized translational elliptical vibrating screen with three excitation motors for solid-liquid separation and solid-phase separation, especially a large-area elliptical vibrating screen used in operations such as coal, mining, metallurgy, and oil drilling. Background technique [0002] The inertial elliptical vibrating screen can be realized with double excitation motors, three excitation motors, or even more excitation motors. When dual excitation motors are used, due to the limitation of the excitation force of the motors, when the screening area of ​​the vibrating screen is large, it is difficult to achieve the working parameters such as the amplitude required for efficient screening of the vibrating screen. Three excitation motors are used to better meet the excitation force requirements of large-area vibrating screens.
