Description

Technical Field

[0001] The invention belongs to the field of screening equipment, and in particular relates to a highly efficient vertical slot arc screen. Background Art

[0002] Vertical slot arc screen is a screening equipment widely used in industry, especially in coal preparation plants and ore dressing plants for pre-dehydration, desludging and de-intermediation of materials. Vertical slot arc screen is mainly composed of bracket, screen seat, screen box, screen plate and feed distribution box. The slot screen plate is usually welded from stainless steel bars. It mainly separates the coal slime water by the sharp edges on the feed side of the slot screen plate. It has the advantages of high opening rate, good de-intermediation and dehydration effect, and long service life.

[0003] When the existing curved screen is working, in order to ensure the screening efficiency, a cleaning device is usually set to clean out the material particles connected to the curved screen in time. For example, the Chinese patent with application number CN202323042524.0 discloses a new protective structure for the curved screen, which cleans the curved screen by setting an electric cleaning roller, and has a good cleaning effect. However, the electric cleaning roller is suitable for curved screens of mesh type and mesh type, but not for vertical slit curved screens. Due to the lack of fixing means on the sharp edges of the slit screen plate on the feeding side of the vertical slit curved screen, the electric cleaning roller is easy to cause the deformation of the vertical slit curved screen when it is connected to the material particles on the slit screen slot of the vertical slit curved screen, which greatly reduces the screening efficiency and service life. If the fixing of the sharp edges on the feeding side of the slit screen plate on the upper part of the vertical slit curved screen is strengthened, the screening area will be reduced, and the screening efficiency will also be reduced. It is necessary to set a cleaning device suitable for the vertical slit curved screen. In addition, the vibration device used in the existing curved screen can only vibrate the entire device, which does not completely improve the screening efficiency and needs further improvement.
