Description

TECHNICAL FIELD

[0001] The application relates to the technical field of circular vibrating screens, in particular to a circular vibrating screen screen mesh fixing structure for mine screening. BACKGROUND

[0002] The circular vibrating screen is a key equipment widely used in the mining, metallurgy and building material industries, and is mainly composed of a screen box, a screen mesh, a vibration exciter, a motor, damping springs and a base. The working principle of the circular vibrating screen is that the motor drives the vibration exciter to rotate to generate centrifugal inertia force, so as to drive the screen box to perform circular motion and realize multi-layer and high-efficiency vibration screening.

[0003] The screen mesh is continuously abraded and stretched by the ore in the use process, the thickness of the screen mesh is gradually reduced, the strength of the screen mesh is also reduced, and finally the screen mesh is prone to breakage. In addition, the traditional screen mesh fixing mode is mainly bolt connection, however, the bolt fixing mode has the defect of easy loosening, so that the relative vibration amplitude between the screen mesh and the screen box is prone to occur. The relative vibration not only reduces the effective vibration of the screen mesh, but also makes the qualified ore difficult to pass through the screen mesh, increases the screening difficulty and reduces the screening efficiency. Meanwhile, the relative vibration also aggravates the abrasion of the screen mesh and the screen box, and shortens the service life of the equipment. CONTENT OF THE INVENTION

[0009] Further, one end of each of the U-shaped insertion rods of the U-shaped vibration frame is fixedly connected with a tension spring, and the other end of each of the tension springs is fixedly connected with the U-shaped vibration frame.

[0010] Through the above scheme, through the setting of the tension spring, the stable fixing purpose of the U-shaped insertion rod to the screen can be realized.

[0016] Through the above scheme, through the setting of the eccentric motor in cooperation with the spring, the vibration purpose of the U-shaped vibration frame can be realized.

[0017] Further, the specifications of each of the screens are different.

[0018] Through the above scheme, through the above setting, the purpose of graded filtration can be realized.
