Problems solved by technology

[0002] At present, various vibrating screens are gradually developing in the direction of large-scale and high-efficiency, and the resulting problems of bulky structure, difficult maintenance, and high manufacturing cost are gradually becoming prominent.
The amplitude and frequency of a vibrating screen are relatively single, and the movement track of the material on the screen surface is single, especially in the screening operation of wet fine particle materials (water content 7-14%, grading particle size 3mm-13mm), the material clogging Holes, low screening rate, small processing capacity and other problems can not be resolved
Although the structure of the arthropod screen and the transmission mode of the screen surface have been partially changed, and sieve plate ribs are added on both sides of the screen surface, the overall screen box is also cumbersome, and maintenance is also very inconvenient, which cannot meet the requirements for grading difficult-to-screen materials.

Embodiment Construction

[0009] An embodiment of the present invention is described in conjunction with accompanying drawing: three vibrating screen units 1, 4, 7 are installed on the foundation after being fixed by damping device 12 and bearing 10, on the screen body of each vibrating screen unit, be provided with vibrating Devices 2, 5, 9. The screen surfaces 3, 6, and 8 of the three vibrating screen units are combined into an overall curved concave arc-shaped screen surface, and the inclination angles of the screen surfaces of each vibrating screen unit are arranged in a gradually decreasing manner from the feeding end to the discharging end. The screen surface inclination angle of vibrating screen unit I is 18°, the screen surface inclination angle of vibrating screen unit II is 24°, and the screen surface inclination angle of vibrating screen unit III is 30°. Each vibrator 2, 5, 9 is respectively driven by a motor transmission device 14, so that each vibrating screen unit generates an elliptical ...

Abstract

The invention relates to a multi-unit combined vibration screen, wherein it is formed by end-to-end connected vibration screen units; each unit is formed by screen tank, screen surface, vibrator, motor transmitter and damping spring; the incline of each screen surface is reduced / increased from inlet to the outlet, to form concave / convex shape. The invention can reduce the device load and avoid resonance.

Description

technical field [0001] The invention belongs to the field of vibrating screening machinery, mainly relates to screening operations of materials in various industries, and is a multi-unit combined vibrating screen that can effectively improve the processing capacity and screening efficiency of the vibrating screen. Background technique [0002] At present, all kinds of vibrating screens are gradually developing in the direction of large-scale and high-efficiency, and the problems of heavy structure, difficult maintenance, and high manufacturing cost are gradually becoming prominent. The amplitude and frequency of a vibrating screen are relatively single, and the movement track of the material on the screen surface is single, especially in the screening operation of wet fine particle materials (water content 7-14%, grading particle size 3mm-13mm), the material clogging Holes, low sieve rate, small processing capacity and other problems can not be resolved. Although the struct...
