Description

Technical Field

[0001] The utility model relates to the technical field of screens, in particular to a fine screen that is easy to disassemble, assemble and replace. Background Art

[0002] Screening is the process of separating a group of bulk materials of different particle sizes into several different levels by passing them through a single or multi-layer screen surface with uniform holes for multiple times. Particles larger than the screen holes remain on the screen surface and are called the oversize of the screen surface. Particles smaller than the screen holes pass through the screen holes and are called the undersize of the screen surface. Ultimately, the separation of coarse and fine particles is achieved, completing the screening process. During the screening process, the screen is severely worn due to continuous friction and screening, resulting in the need for frequent replacement of the screen.

[0003] The mesh number of the existing screen is fixed and cannot be changed during use. When screening, multiple screen assemblies with different mesh numbers are often required for multi-level fine screening. The mesh number of a screen assembly cannot be directly adjusted. Therefore, a screen that can change its own mesh number for fine screening is needed. Utility Model Content

The material is first screened on the filter plate 1, and then the screened material is screened on the filter plate 2. After that, the double-threaded screw is rotated by hand to make the installation frame 1 and the installation frame 2 move and slowly overlap, so that the filter plate 1 and the filter plate 2 overlap, and the mesh holes are staggered to form a new combined filter. Then the screened material is screened once, and the screening work is ended. The screen can be adjusted to change its own mesh number to form a new screen, and the material can be screened in multiple stages to ensure the fine screening of the material.

[0016] 2. The fine screen that is easy to disassemble and replace is fixed by the fixing frame, T-slot, T-block, card slot and card block.
