After the filter plates 300 are embedded into the vertical pipes 100 and switched to a horizontal state, part of edges of the filter plates 300 are supported on the bottom walls of the transverse through holes 120, so that the filter plates 300 embedded into the vertical pipes 100 can keep stable states; after the filter plates 300 in the horizontal state are drawn out of the vertical tubes 100, the filter plates 300 can be automatically switched to the discharging state, impurities are automatically separated from the filter plates 300 due to gravity, so that automatic discharging is realized, and the ejector pins 510 of the needle plates 500 on the corresponding sides are inserted into the filter holes 310 to clean out the impurities in the filter holes 310, and it is understood that in order to reduce structural interference, the diameters of the ejector pins 510 are smaller than the diameters of the filter holes 310. An impurity collecting device (e.g., an impurity collecting box) may be generally disposed at a lower position of the left and right sides of the vertical pipe 100 so as to receive the discharged impurities, thereby achieving automatic discharging and collecting.
