[0022] In this embodiment, servo motor 9 drives scraper 10 to rotate, and scraper 10 scrapes the top surface of filter plate 4 to avoid slag from blocking filter holes 5.

[0023] Specifically, please refer to Figure 1A drain valve 15 is fixedly installed on the side of the bottom end of the siphon tank 2. One end of the drain valve 15 extends to the bottom of the inner cavity of the siphon tank 2, and the other end of the drain valve 15 is fixedly connected to a drain pipe 16.

[0030] In this embodiment, the water pipe is connected to the external water pipe via the connecting valve 14 so that water can be injected into the inner cavity of the siphon tank 2 through the water injection valve 13.

[0031] Working Principle: In use, first place the support plate 1 above the sedimentation tank, ensuring the bottom end of the inlet pipe 6 extends into the sedimentation tank. Connect the external water pipe to the connecting valve 14, allowing external water to be injected into the inner cavity of the siphon tank 2 through the water injection valve 13. Then, start the horizontal centrifugal pump 8 to pump water into the suction pipe 7. The suction pipe 7 draws water out of the inner cavity of the siphon tank 2, causing the water to move downwards. Simultaneously, a negative pressure is generated in the upper part of the inner cavity of the siphon tank 2. This negative pressure then forces the inlet pipe 6, which extends into the sedimentation tank, to generate… The suction force is used to draw the slurry from the sedimentation tank through the slurry inlet pipe 6, allowing the slurry to enter the inner cavity of the siphon tank 2. At the same time, the slurry is filtered through the filter holes 5 on the filter plate 4, allowing the slag to be filtered down. The slurry that falls down enters the lower part of the inner cavity of the siphon tank 2 for extraction by the liquid extraction pipe 7 and the horizontal centrifugal pump body 8. Finally, the servo motor 9 is started at regular intervals to drive the scraper 10 to rotate. The scraper 10 scrapes the slag filtered down from the top surface of the filter plate 4 to prevent clogging of the filter holes 5. In addition, the sealing cover 12 can be opened to clean out the slag through the slag discharge pipe 11.
