[0008] Technical effects and advantages of the utility model:

[0009] The utility model further filters the sludge by setting the filter frame, filter net and pull ring in the filter assembly, and then other sludge will enter the interior of the collection tank. At the same time, the filter net filters the sludge to achieve the effect of separating sewage and sludge, which is convenient for the operator to handle the sludge. After use, the operator can take out the filter frame and filter net from the inside of the sludge discharge device through the set pull ring for cleaning.
