Material screening and impurity removing device

Abstract

The invention discloses a material screening and impurity removing device comprising a support. A bearing seat is fixedly connected to the rear side of the support. A motor is fixedly connected to theupper portion of the bearing seat. A coupling is fixedly connected to the output end of the motor. A left rotary shaft is fixedly connected to the front end of the coupling and is rotationally connected with the left side of the support. A left rotary wheel is fixedly connected to the outer side of the left rotary shaft. A right rotary shaft is rotationally connected to the right side of the support. A right rotary wheel is fixedly connected to the outer side of the right rotary shaft. The left rotary wheel and the right rotary wheel is sleeved with a conveying belt. The outer side of the conveying belt is provided with a plurality of air holes. A plurality of conveying lugs are fixedly connected to the inner side of the conveying belt. The front sides of the left rotary wheel and the right rotary wheel are sleeved with front baffles. Compared with the prior art, the material screening and impurity removing device has the beneficial effects that the structure is simple, use is convenient, light impurities in materials can be screened out and removed during use, then pure materials are obtained, and the impurity removing rate is high.

Description

technical field [0001] The invention relates to a screening device, in particular to a material screening and impurity removal device. Background technique [0002] Screening is the process of using one or more sieve surfaces to divide mixed waste with different particle sizes into two or more particle groups. Screening often has two operations, wet selection and dry selection. Dry selection is often used for solid waste screening, and multiple screen surfaces can be screened at the same time. The screening process can be divided into two processes: material stratification and fine-grained sieving, in which fine-grained sieving is the purpose of separation. [0003] Existing devices can only sieve materials into large and small materials at one time, but light impurities cannot be removed well, especially impurities with a certain quality that are difficult to remove by ordinary winnowing. For this reason, those skilled in the art have proposed a material screening and imp...
