Description

Technical Field

[0001] The utility model relates to the field of mixed material screening, in particular to a screening device for soil-rock mixed materials with a large mud content. Background Art

[0002] Screening is a method of separating particle groups according to their powder properties such as particle size, specific gravity, charge and magnetism. The operation of using a perforated screen to separate mixed materials of different particle sizes into various particle size levels is called screening, and the operation of using sieves with different mesh sizes to separate solid materials according to the required particle size. It is often combined with crushing to make the particle size of the crushed material nearly equal to ensure that it meets certain requirements or avoids excessive crushing. In the production process, the existing soil-rock mixture needs to be screened to separate the soil and rock from other mixtures.

[0003] A Chinese patent discloses a screening device for soil-rock mixtures with a large amount of mud (authorization announcement number CN214289338 U). This patented technology can solve the problem that in the traditional screening process, screening is generally performed through a filter screen, and the filter screen is prone to clogging during the screening process. At the same time, some mixtures that are not thoroughly screened cannot be circulated and screened. They need to be taken out manually and then screened, which reduces the practicality problem.

[0004] However, the existing screening device has a single screening method, resulting in an unsatisfactory screening effect. In addition, the screening net is installed in the cavity, and the filter holes may still be blocked after long-term use, resulting in unsatisfactory use effect and difficulty in cleaning. Summary of the invention

[0006] Preferably, the connecting rod and the first spring rod are screwed together via an adjusting bolt.

[0007] Preferably: a base frame is installed on the outer side wall of the connecting rod along its circumferential direction, and a first filter screen is arranged on the upper end of the base frame.

[0008] Preferably, the outer wall of the cavity is symmetrically provided with openings, and a recovery chamber is installed at the bottom of the cavity.

[0009] Preferably, the recovery cavity is connected by clamping two semi-circular cavities.

[0010] Preferably, handles are symmetrically installed on the left and right sides of the inner end of the second filter screen, and the handles are in a U-shaped structure.

[0011] The technical effects and advantages of the present utility model:

[0012] 1. In the present utility model, an adjustment motor, a first spring rod, and a second spring rod structure are adopted to drive the first filter screen and the second filter screen to rotate and vibrate up and down, further improving the screening effect of the mixed material and avoiding blockage of the mesh holes.

[0013] 2. In the present utility model, an adjustment bolt structure is adopted, so that after the first filter screen and the second filter screen are used for a long time, it is convenient to disassemble and clean them. Description of the Drawings
