[0028] Working principle:

[0029] Embodiment 1

[0030] For the sludge with excellent fluidity but not flowing smoothly, it can be put into the inside of the feeding barrel 5 through the feeding trough. At the same time, the brake servo motor 7 is started, and the brake servo motor 7 drives the screw rod 6 to rotate, and then the screw rod 6 spirally transports the sludge inside the feeding barrel 5. At the same time, the screw rod 6 spirally stirs the sludge to make the sludge more dispersed;

[0031] The sludge then automatically enters the interior of the first treatment box 3 through the discharge trough of the feed barrel 5, and then enters the inner side of the bottom of the first treatment box 3 under the filtration of the first filter plate 11, and various impurities filtered out of the sludge will be temporarily retained on the top of the first filter plate 11. Then, the sludge suction pump 2 is started and the solenoid valve inside the first solenoid valve tube 9 and the solenoid valve inside the second solenoid valve tube 10 are opened. The sludge at the bottom of the first treatment box 3 is automatically pumped to the interior of the second treatment box 4 through the first solenoid valve tube 9 and the second solenoid valve tube 10 by the sludge suction pump 2. This reciprocating process achieves targeted cleaning of the sludge. After the first filter plate 11 has been used for a period of time, the movable door 8 can be opened to centrally clean the impurities collected on the top of the first filter plate 11 to ensure the filtering effect of the first filter plate 11.

[0032] Embodiment 2

[0033] For the sludge with poor fluidity and partial drying, it can be put into the feeding tube 5 through the feeding trough. At the same time, the brake servo motor 7 is started, and the brake servo motor 7 drives the screw rod 6 to rotate, and then the screw rod 6 spirally transports the sludge inside the feeding tube 5. At the same time, the screw rod 6 spirally stirs the sludge to make the sludge more dispersed.

[0034] The sludge then automatically enters the first treatment box 3 through the discharge trough of the feed barrel 5. Then, the sludge suction pump 2 is started and the solenoid valves in the third solenoid valve tube 12 and the fourth solenoid valve tube 13 are opened, so that the sludge suction pump 2 pumps the water placed in the re-output space of the second treatment box 4 before the operation or the water filtered by the second filter plate 15 after the operation to the U-shaped tube 14 through the third solenoid valve tube 12 and the fourth solenoid valve tube 13, and then the sludge on the first filter plate 11 is reversely flushed through the U-shaped tube 14, and then enters the bottom inner side of the first treatment box 3 under the filtration of the first filter plate 11, and various impurities filtered out of the sludge will be temporarily retained on the top of the first filter plate 11. After completion, the first solenoid valve tube 9 and the second solenoid valve tube 10 are closed;

[0035] Next, the solenoid valve inside the first solenoid valve tube 9 and the solenoid valve inside the second solenoid valve tube 10 are opened, and the sludge at the bottom of the first treatment box 3 is automatically pumped to the inside of the second treatment box 4 by the sludge suction pump 2 through the first solenoid valve tube 9 and the second solenoid valve tube 10. Under the filtration of the second filter plate 15, most of the sludge is separated from the water, and the water enters the output space. Then, the above steps are repeated to achieve targeted cleaning of the sludge. After the first filter plate 11 has been used for a period of time, the movable door 8 can be opened to centrally clean the debris collected on the top of the first filter plate 11 to ensure the filtering effect of the first filter plate 11.
