Description

Technical Field

[0001] The utility model relates to the technical field of impurity removal equipment, and more specifically to an impurity removal sieve for improving impurity removal efficiency. Background Art

[0002] During the grinding and separation of minerals in underground mines of metal and non-metal mines and the water treatment process, detonator fragments, detonating cord residues, flocculent impurities or cloth-like impurities are often encountered. The intervention of these impurities will have a very bad impact on the ore dressing system, such as blocking pipelines, affecting separation, reducing the recovery rate, and having an adverse impact on the normal operation of equipment. Therefore, an impurity removal sieve is needed to perform impurity removal and screening on the ore.

[0003] After retrieval, the existing patent (publication number: CN211587405U) discloses an impurity removal sieve. During its use, the ore material is put into the inside of the sieve cylinder, and then the sieve cylinder is driven to rotate to screen the ore material. During the use of the sieve cylinder, a brush roller driven by a driving component rotates to sweep off the impurities attached to the sieve cylinder, greatly reducing the amount of impurities attached to the outer wall of the sieve cylinder, avoiding replacing the sieve cylinder multiple times, and ensuring the screening efficiency of the sieve cylinder for the material. However, the inventor found the following problems in the prior art during the implementation of the present utility model: For the above-mentioned impurity removal sieve, when screening the impurities in the ore material using the sieve cylinder, the centrifugal force generated after the rotation of the sieve cylinder acts on the surface of the impurities, and the ore itself is blocked by the sieve cylinder, thus completing the work of screening and separating the impurities. However, the mass of the impurities is relatively light, so the centrifugal force received by the impurities is also small. Therefore, relying solely on centrifugal force for screening during the impurity removal process has the defect of low screening efficiency and is difficult to meet the use requirements.

[0004] In view of this, the present utility model provides an impurity removal sieve for improving impurity removal efficiency. Summary of the Utility Model
