Description

Technical Field

[0001] The utility model relates to the technical field of wollastonite powder screening, and more specifically, to a magnetic attraction and shaking screening device for ultra-fine wollastonite powder. Background Art

[0002] Wollastonite is a triclinic crystal system with fine plate-like crystals and radial or fibrous aggregates. Wollastonite powder has needle-like and fibrous crystal forms, high whiteness and unique physical and chemical properties. The production of wollastonite powder requires screening of bulk raw materials.

[0003] The utility model patent with patent publication number CN207615178U discloses a magnetic attraction and shaking screening device for ultra-fine wollastonite powder. The advantage of this structure is that by setting a double-axis extension motor, it can drive the feed shaft to rotate and the L-shaped support rod to rotate. When the double-axis extension motor drives the feed shaft to rotate, the spiral blades can be used to control the feeding speed. When the double-axis extension motor drives the L-shaped support rod to rotate, when the second permanent magnet is located above one of the first permanent magnets, the second permanent magnet and the first permanent magnet are magnetically attracted, and the extension plate moves upward, so that the screen can be tilted. As the L-shaped support rod rotates, the second permanent magnet continuously attracts each first permanent magnet, which can form an effect of tilting the outer ring gap of the screen upward, thereby improving the screening effect and efficiency.

[0004] However, in actual use, this structure needs to be disassembled and cleaned after a period of use because the wollastonite powder is easily adsorbed on the surface of the screen after screening. Since the screen is installed inside the machine body through a reinforcement ring and an extension plate, and the extension plate is connected to the through hole on the surface of the machine body through a supporting spring, it is not convenient to disassemble the screen, which will affect the effect of the machine body on screening wollastonite powder.
