[0029] Sewage treatment is a key link in municipal engineering. Usually, large particles that may be contained in sewage are filtered and intercepted through the use of a filter net. However, the accumulation of these particles on the filter net will cause the filter net to be blocked, thereby affecting the filtering effect and normal use of the device. By setting an anti-blocking structure 5, not only can the accumulated impurities be effectively removed from the filter net, but they can also be stored and taken out for cleaning, which greatly increases the convenience of use.
