For example, the patent with application number 201920325465.2 proposes a centrifugal solid-liquid separation device for industrial wastewater treatment, including a solid-liquid separation box body, a bottom liquid receiving box and a solid-liquid separation drum. The lower end of the solid-liquid separation box body is installed with a bottom liquid receiving box by screws, and the upper end of the bottom liquid receiving box is integrally provided with a collecting filter plate. The filling ring groove of the solid-liquid separation drum in the utility model is filled with a filter cotton layer, and it has a filtering and purification effect during the rotation of the solid-liquid separation drum for solid-liquid separation, which reduces the subsequent treatment of the wastewater, has a filtering effect while separating the solid and liquid, and has perfect functions. In the above scheme, a sealing door is provided at the left end of the solid-liquid separation drum, which has strong sealing performance and is convenient to open and clean the impurities inside the filling ring groove.

[0003] However, after the solid-liquid separation is completed in the centrifugal device in the above scheme, solid impurities will remain on the outer wall of the internal separation tank. The separation tank needs to be taken out as a whole for easy cleaning, which is cumbersome and reduces work efficiency. Therefore, we have made improvements to this and proposed a centrifugal device for wastewater treatment. Utility Model Content
