Description

Technical Field

[0001] The utility model belongs to the technical field of silicon slag treatment, in particular to an adjustable screening structure for silicon slag. Background Art

[0002] Silicon slag is a white solid substance separated by the desiliconization operation. Because silicon slag contains alumina and alkali, it is generally returned to the preparation of raw materials for addition. During the collection process of silicon slag used in industrial silicon smelting, a screening device is also required to screen the silicon slag for subsequent separation, recovery and processing.

[0003] In the Chinese utility model patent with publication number CN217595156U, a vibrating screen for screening industrial silicon slag is disclosed. The fixed rod is driven to rotate by a turntable, and the swing arm is driven to swing back and forth under the limiting action of the movable groove. Under the mutual cooperation of the support rod and the clamping plate, and the hinged action of the connecting rod, the screening box is driven to swing back and forth to screen the silicon slag. However, since the device uses a multi-stage screening method to screen the silicon slag, during the process of concentrated silicon slag input, due to the slow screening speed of the screen plate mesh, a small amount of silicon slag may not be discharged according to the corresponding discharge chute, resulting in low screening accuracy and easy confusion. In addition, the device is large in size and complex in structure.

[0004] Therefore, there is an urgent need to improve the existing vibrating screen used for screening industrial silicon slag materials and provide an adjustable screening structure for silicon slag with a screening aperture that can be quickly adjusted. Utility Model Content
