Description

Technical Field

[0001] The utility model relates to the technical field of ore screening, and particularly relates to a screening device for reducing material adhesion. Background Art

[0002] A vibrating screen works by the reciprocating spiral vibration generated by exciting the vibrator. The upper rotating weight of the vibrator causes the screen surface to generate planar gyratory vibration, while the lower rotating weight causes the screen surface to generate conical gyratory vibration. The combined effect makes the screen surface generate compound spiral vibration. The vibrating screen uses a vibrating motor as the vibration source to excite, so that the material is thrown up on the screen and moves forward in a straight line at the same time. The material uniformly enters the feed inlet of the screening machine from the feeder, and through multiple layers of screen meshes, several specifications of oversize and undersize materials are produced and discharged from their respective outlets. It has the advantages of stable and reliable operation, low consumption, low noise, long service life, stable vibration mode, high screening efficiency, etc. It is a highly efficient and new type of screening equipment and is widely used in industries such as mining, coal, smelting, building materials, refractory materials, light industry, and chemical industry.

[0003] Patent Publication No. CN220879542U discloses a screening device, which includes a screening box. A screen mesh extending transversely is arranged in the screening box, and there are a plurality of through screen holes on the screen mesh; a driving assembly, including a driving member and a transmission member. The middle part of the transmission member is hinged to the inner wall of the screening box, the driving member is drivingly connected to the first end of the transmission member, so that the transmission member can swing relative to the screening box, and the second end of the transmission member is drivingly connected to the screen mesh, so that the screen mesh reciprocates transversely.

[0004] In order to solve the problem of large power consumption cost of the screening device, the prior art is to adopt a method of only driving a transmission member by one driving member to realize the reciprocating movement of the screen mesh, thereby reducing the power consumption. However, there will still be a situation where the dust attached to the material cannot be cleaned, resulting in the problem of insufficient screening. Summary of the Utility Model
