[0002] In the current sludge treatment process, the presence of solid impurity particles such as stones in the treated sludge to varying degrees affects the treatment effect of the sludge. If it is not treated, it may cause unnecessary damage to the equipment. The common treatment method in the existing structure is to filter the solid impurities through a filter screen.

[0003] A Chinese utility model patent with reference application number CN2015207290912 discloses a solid filter for a slurry conveying process. The solid filter for the slurry conveying process achieves the effect of filtering solids in sludge by setting a filter screen.
