Description

Technical Field

[0001] The utility model relates to the technical field of screening, in particular to a screening and separation device. Background Art

[0002] A screening machine is a vibrating screening machine that uses the relative motion between bulk material and the screen surface to force some particles through the sieve holes, thereby separating materials such as sand, gravel, and crushed stone into different grades based on particle size. The screening process is generally continuous. After the raw material is fed to the screening machine (referred to as the sieve), material smaller than the sieve hole size passes through the sieve holes and is called the undersize product. Material larger than the sieve hole size is continuously discharged from the sieve surface and is called the oversize product.

[0003] However, the existing screening device has certain disadvantages. During the screening process, special-shaped materials are easily stuck in the screen holes, which affects the screening of the materials. The existing screening device needs to clean the screen holes regularly after use. The device needs to be stopped for cleaning. The process is cumbersome and the screen holes cannot be cleaned automatically, which affects the efficiency of material screening. Utility Model Content
