In the process of sewage filtration, the circulation system 103 is used to transport the sewage at the bottom of the treatment box 101 to the water distribution system 102 for circulation filtration, and in the process of using the multiple filter plates 105 to perform preliminary filtration on the sewage, the pulling mechanism can be started in sequence to drive the The corresponding filter plate 105 is disengaged from the corresponding through groove 117. When the filter plate 105 moves to the inside of the corresponding cleaning box 118, the driving mechanism is started to drive the cleaning roller 119 to rotate, and the cleaning roller 119 is used to clean the current filter plate 105. After cleaning, the pulling mechanism is used to drive the filter plate 105 to reset.

The servo motor 109 is started, and the output gear 110 and the transmission gear 120 cooperate to drive the limit shaft 106 to rotate at the end of the cleaning box 118. Since the limit shaft 106 does not move when rotating, the threaded rod 107 is displaced when rotating inside the limit shaft 106, so that the filter plate 105 is driven to slide at the through groove 117 with the cooperation of the connecting bearing 108, so that the filter plate 105 gradually separates from the filter box 104.

When the filter plate 105 moves to the corresponding cleaning box 118, the driving mechanism is started to drive the cleaning roller 119 to rotate, and the cleaning roller 119 is used to clean the current filter plate 105. After cleaning, the pulling mechanism is used to drive the filter plate 105 to reset. With the above structure, in the process of using the filter plate 105 to perform preliminary filtering of solid particles in sewage, at least one filter plate 105 is always kept filtering sewage, so that there is no need to stop the machine to clean the preliminary filtering mechanism, and the continuous treatment of decentralized sewage can be achieved, avoiding affecting the sewage treatment efficiency.
