[0028] In this embodiment, the bottom end of the central axis 5 is fixedly connected to the inner bottom surface of the feed trough 2, and the outer side of the central axis 5 is fixedly connected with a spiral piece 6. The outer side of the spiral piece 6 fits with the inner side of the filter cartridge 4. The top side of the filter cartridge 4 is fixedly connected with a sewage pipe 7. The end of the sewage pipe 7 is slidably connected with a protective ring 13. The device can be connected to the pipeline of the external sludge equipment through the sewage pipe 7. The protective ring 13 can protect the connection. The central axis of the protective ring 13 coincides with the central axis of the sewage pipe 7. The motor 17 is started to rotate the central axis 5. The feed trough 2 and the spiral piece 6 can be rotated by the rotation of the central axis 5. When the feed trough 2 rotates, the sludge can be drawn into the feed trough 2 by using the feed port 3. The rotation of the spiral piece 6 can draw the sludge in the feed trough 2. The sludge is transported upward along the filter cylinder 4 and discharged from the device through the drain pipe 7 to extract the sludge and achieve the purpose of dredging. At the same time, when the sludge moves up in the filter cylinder 4, the mesh structure on the outside of the sludge can be used to filter the sludge. The bottom of the protective cylinder 1 is fixedly connected to a limit ring 15, and an annular groove 16 is provided on the outside of the top of the feed trough 2. The annular groove 16 and the limit ring 15 are movably connected, and the inner size of the annular groove 16 is consistent with the outer size of the limit ring 15.

The protective ring 13 can protect the connection. The feed trough 2 of the device is placed in the sludge by using the lifting equipment, and the motor 17 is started to rotate the central axis 5. The feed trough 2 and the spiral blade 6 can be rotated by the rotation of the central axis 5. When the feed trough 2 rotates, the sludge can be rolled into the feed trough 2 by the use of the feed port 3. The sludge in the feed trough 2 can be transported upward along the filter cartridge 4 by the rotation of the spiral blade 6, and passed through the sewage discharge port. The pipe 7 discharges the device to extract the sludge to achieve the purpose of dredging. At the same time, when the sludge moves up in the filter cylinder 4, the mesh structure on the outside of the sludge can be used to filter the sludge, so that the sewage in the sludge enters the cavity of the protective cylinder 1 and the filter cylinder 4. Through the coordinated use of the water pump 11 and the drain pipe 12, the sewage in the cavity between the protective cylinder 1 and the filter cylinder 4 can be pumped out, so that the device can filter the sludge while dredging, and there is no need to filter the sludge through external equipment, thereby improving the practicality of the device. At the same time, the rotation of the feed trough 2 can cause the drill bit 14 to rotate, which is convenient for the feed trough 2 to enter the sludge. The coordinated use of the annular groove 16 and the limit ring 15 can ensure the stability of the rotation of the feed trough 2.
