A screening device for separating chemical raw materials

Abstract

The invention relates to the field, in particular to screening equipment for separating chemical raw materials. The screening equipment comprises an accommodating box body, a positioning and separating device, a screening drive device and an excessive material recovery device. The accommodating box body is of a hollow structure. A feeding pipeline for feeding chemical raw materials to be separatedis arranged on the outer side wall of the accommodating box body. A discharging pipeline in butt joint with the bottom of the excessive material recovery device is arranged at the bottom of the accommodating box body. The screening drive device comprises a positioning drive part, a positioning transmission part installed at the output end of the positioning drive part and a transmission connection part installed at the end of the positioning transmission part. The positioning and separating device comprises a bearing and screening part and a separating and gathering part which are arranged from top to bottom in the vertical direction. The separating and gathering part is clamped to the bottom of the bearing and screening part. The transmission connection part is in transmission connectionwith the bearing and screening part. By the adoption of the screening equipment, the output of manpower is reduced, the working efficiency of the separation operation is improved, and the accuracy ofthe separation operation is improved as well.

Description

technical field [0001] The invention relates to the field, in particular to a screening device for separating chemical raw materials. Background technique [0002] In the production process of many granular organic chemical raw materials, a large amount of dust will be generated, which is mixed with a large amount of powder of organic chemical raw materials, and there are many impurities that are harmful to the human body and easy to cause environmental pollution. Therefore, special equipment should be used A device is used to recover and process this part of dust. [0003] In the prior art, the chemical raw materials are separated by manually placing the chemical raw materials to be processed on the screening yarn, and then the operator shakes them. During the shaking process, the light-weight and small-particle The raw material will leak from the through hole of the screening yarn, and the raw material with large particles will remain on the screening yarn. The screening ...
