[0002] Organic silicon liquid silicone is mainly produced by combining main materials such as white carbon black, 107 base rubber, and dimethyl silicone oil. During the production process, various impurities and dust will be mixed into the liquid silicone. Therefore, before the subsequent production of liquid silicone, an impurity screening device needs to be used to remove impurities.
[0003] Existing liquid impurity screening devices mostly use screening tanks for impurity screening. Since liquid silicone is relatively viscous, when performing impurity screening, a stirring mechanism needs to be used for stirring to assist in discharging materials.
