Impurity collecting device used for powder filtering device

Abstract

The invention discloses an impurity collecting device used for a powder filtering device. The impurity collecting device comprises a filter bin, wherein a drainage bin with a conical cross section is arranged at the lower end of the filter bin, an opening is arranged at the lowest end of the drainage bin, a flange plate is arranged at the opening, and a cloth bag is bound on the flange plate. According to the impurity collecting device used for the powder filtering device, impurities are accumulated on a drawing plate after the filtering bin is used for a long time, and when the impurities need to be cleaned, the cloth bag is sleeved on the lower end of the drainage bin, the drawing plate is shaken and pulled outwards, the impurities on the drawing plate fall into the drainage bin so as to slide into the cloth bag.

Description

technical field [0001] The invention relates to a powder filtering device, in particular to an impurity collecting device for the powder filtering device. Background technique [0002] Before the matting powder is prepared, the massive minerals need to be pulverized and filtered, and finally the fine powder can be collected before use. [0003] Usually, the materials pulverized by the pulverizer are mixed with large particles and small particles, and are manually screened through a sieve, but the fineness of the screen is not enough, the labor intensity is high, the efficiency is low, and the product quality is not good enough. [0004] Specially invented a powder filter device, including a filter chamber, the upper end of the filter chamber is connected to the feed pipe and the air pipe, and a multi-layer filter cloth is arranged in the filter chamber, and a pull-out plate is provided at the bottom of the filter cloth at the bottom layer. The side wall of the filter bin ab...

AI Technical Summary

Problems solved by technology

After the filter chamber has been used for a long time, there will be a lot of useless impurities left on the drawing plate, which need to be cleaned up. Therefore, the drawing plate needs to be pulled out, and if there are many impurities on the drawing plate, it will take a long time to clean it. Be careful, and it's heavy, and it's not convenient to pour it out
