[0002] Industrial solid waste is solid waste generated in the process of industrial production, and this waste is also a recyclable resource. Through secondary treatment of this part of industrial solid waste, the raw materials needed for production can be extracted from it, thereby reducing production costs and improving resource utilization. One of the most common equipment in the process of industrial solid waste treatment is the circular vibrating screen. The circular vibrating screen is a new type of vibrating screen with circular vibration, multiple layers and high efficiency.

The utility model can not only install multiple filter screens, but also adjust the angle of the filter screen to meet more different work needs. However, it still has the following disadvantages in actual use:

[0004] The above-mentioned bidirectional discharge circular vibrating screen has two parallel control panels, and multiple filter screens are arranged between the two control panels. However, because the filter screens are arranged inside the circular vibrating screen, when the filter holes are blocked, the screen needs to be shut down for cleaning and maintenance, which delays the screening production work.

Therefore, when screening different materials, all or part of the filter screens need to be replaced to meet the screening requirements of the materials. The need to equip multiple filter screens with different apertures causes high costs and affects the screening progress. Utility Model Content
