Description

Technical Field

[0001] The utility model relates to the technical field of concentration and screening, and more specifically, to a specific gravity type concentration and screening device. Background Art

[0002] Selective screening refers to the fine screening and grading of granular materials to achieve the purpose of accurate classification and selection of granular materials. In the actual screening process, the size of some particles is similar to the mesh of the screen, so during the swing screening, these particles will be stuck inside the mesh, thereby blocking the mesh and affecting the subsequent screening.

[0003] After searching, a Chinese patent with announcement number CN219616088U discloses a particle screening device. Through the mutual cooperation of parts such as a screening frame, a discharge port and a discharge device, when the discharge structure is working, the cable particles inside the screening frame will leave the screening frame from the discharge port, thereby realizing the particle screening operation.

[0004] When the above-mentioned screening device is in use, the swing motor can drive the screening frame to swing, thereby swinging and screening the particles inside the screening frame. The screening frame generally screens according to the shape of the particles, and is divided into larger particles and smaller particles, but it is not convenient to screen according to the specific gravity of the particles.
