Abstract

The invention discloses a rotary classifying screen with adjustable amplitude and inclination angle. The rotary classifying screen comprises a screen drum, supporting frames and a vibrating device; the screen drum is rotatably installed between the two supporting frames through a rotating shaft; the vibrating device is located below the screen drum, and the vibrating device makes contact with the head end of the screen drum; and the tail end of the screen drum is connected with an amplitude and inclination adjusting mechanism. When the rotary classifying screen is used, a lead screw can be driven to rotate by starting a motor, so that a sliding block is driven to move up and down, the inclination angle of the screen drum is adjusted, initial extrusion force on a damping spring is different due to the fact that the inclination angle of the screen drum is different, therefore, the initial compression length of the damping spring is changed, and the amplitude of the screen drum during vibration is changed.

Description

technical field [0001] The invention relates to the technical field of classifying screens, in particular to a rotary classifying screen with adjustable amplitude and inclination angle. Background technique [0002] Grading screen, also known as screening machine, is a commonly used screening machine in China. It is mainly used in the mineral processing process in mining. Vibration is generated by vibrating motors and springs, with small amplitude and high frequency to ensure that materials have greater kinetic energy and inertia. Can form self-cleaning effect. In addition, this machine has the characteristics of small size, convenient operation and reliable operation. It is mainly used for grading and screening finished compound fertilizers, and is also suitable for raw materials in various industries such as grain, food, chemical, sugar, mining, coal mines, metallurgy, and papermaking. and screening and grading of finished products. [0003] However, when the existing ro...
