[0037] A support plate 12 is fixedly connected in the water inlet cavity 11, and a plurality of water holes are arranged on the support plate 12. A damping ring 13 is fixedly connected to the support plate 12. A rotating column 14 is rotatably connected to the support plate 12, and an impeller I 15 is fixedly connected to the rotating column 14. An impeller II 16 is fixedly connected to the conversion plate 31, and a torsion spring is fixedly connected between the impeller II 16 and the impeller I 15. The damping ring 13 is in contact with the rotating column 14, and the impeller II 16 and the impeller I 15 are both located in the water inlet cavity 11.

[0038] The water inlet tray 22 is fixedly connected to two sewage pipes 25, which are respectively connected to the two sewage holes 24. The mounting bracket I 21 is fixedly connected to two telescopic mechanisms 26. A sewage motor 27 is fixedly connected to the telescopic end of the telescopic mechanism 26. A spiral shaft 28 is fixedly connected to the output shaft of the sewage motor 27. The spiral shaft 28 is located in the sewage pipe 25.

[0039] The conversion disk 31 is fixedly connected with four communicating holes 33, and the four communicating holes 33 are respectively connected with four filtering holes 32. An expansion cavity 35 is fixedly connected in the filtering hole 32, and the expansion cavity 35 is connected with the communicating holes 33. The outer side of the conversion disk 31 is rotatably connected with an air pressure ring 36, and four air pressure pipes 37 are fixedly connected to the air pressure ring 36. Four communicating grooves 38 are arranged in the air pressure ring 36. The air pressure ring 36 is fixedly connected to the connecting column 39, and the four communicating grooves 38 are respectively connected with the four air pressure pipes 37. The communicating grooves 38 can be misaligned and connected with the communicating holes 33.

[0040] The expansion cavity 35 is conically arranged, the inner diameter of the rear end of the expansion cavity 35 is larger than the inner diameter of the front end of the expansion cavity 35, and the thickness of the rear end of the expansion cavity 35 is smaller than the thickness of the front end of the expansion cavity 35;

[0041] The water outlet plate 42 is fixedly connected with a water outlet cavity 44, and the water outlet cavity 44 is connected with the two water outlet holes 43;

[0042] The water inlet cavity 11 is fixedly connected with a connecting pipe 53, a feeding cavity 51 is fixedly connected with the connecting pipe 53, a placing pipe 52 is fixedly connected with the feeding cavity 51, a feeding tray 54 is rotatably connected in the feeding cavity 51, and a plurality of feeding slots 55 are arranged on the feeding tray 54;

[0043] The loading cavity 51 is fixedly connected with a power mechanism for driving the loading tray 54 to rotate;

[0044] When using, Figure 2 As shown, the sewage to be treated is continuously introduced into the water inlet cavity 11, the sewage enters the water cavity 11, the water cavity 11 is connected with the two water inlet holes 23, and then the sewage enters the water inlet hole 23, the water inlet hole 23 is connected with the filter hole 32, the sewage in the water inlet hole 23 enters the filter hole 32, when the sewage passes through the filter hole 32, the filter plate 34 filters the sewage, the dirt in the sewage is isolated, the purified sewage passes through the filter plate 34, enters the water outlet hole 43 through the filter hole 32, enters the water outlet cavity 44 through the water outlet hole 43, and is discharged through the water outlet cavity 44;

[0045] When the filter plate 34 needs to be replaced and the replaced filter plate 34 needs to be cleaned, the driving gear rotates, and a servo motor can be fixedly connected to the connecting column 39. The output shaft of the servo motor drives the driving gear to rotate, and the driving gear drives the ring gear to rotate, and the ring gear drives the conversion disk 31 to rotate, and the conversion disk 31 drives the multiple filter holes 32 to move, so that the filter holes 32 originally located at the water inlet hole 23 move to the sewage hole 24 side, and the filter holes 32 located on the sewage hole 24 side move to the water inlet hole 23 side. The filter holes 32 moving to the sewage hole 24 side will drive the dirt isolated therein to move to the sewage hole 24 side, and at the same time, the newly cleaned filter plate 34 will move to the water inlet hole 23 side to continue filtering the sewage, thereby ensuring the sewage purification efficiency;

[0046] When it is necessary to clean the filter plate 34 on the drain hole 24 side, the air pressure pipe 37 is connected to the air pump through the air pipe in advance, and the air is passed into the expansion cavity 35 on the drain hole 24 side through the air pump. The expansion cavity 35 contains sewage filtered by the filter plate 34. Fig.13As shown, the gas enters the connecting groove 38 through the air pressure pipe 37, and the gas in the connecting groove 38 enters the expansion cavity 35 through the connecting hole 33. The expansion cavity 35 is set in a conical shape, and the thickness of the front end side wall of the expansion cavity 35 is greater than the thickness of the rear end side wall of the expansion cavity 35. The front end here refers to Fig.13 The left side of the Fig.13 The right side of the expansion chamber 35 is shown in FIG. 2 , so that when the gas is introduced into the expansion chamber 35, the rear end of the expansion chamber 35 expands first, and the purified sewage in the expansion chamber 35 is squeezed out to the front side, so that the purified sewage washes the filter plate 34, and moves from the rear side to the front side of the filter plate 34, and washes the dirt in the filter hole of the filter plate 34, flushes the dirt in the filter hole, completes the cleaning of the filter plate 34, and starts the sewage discharge motor 27, and the output shaft of the sewage discharge motor 27 starts to rotate, and the output shaft of the sewage discharge motor 27 drives the spiral shaft 28 to rotate, so that the spiral shaft 28 rotates in the sewage discharge pipe 25, and the dirt in the sewage discharge pipe 25 is discharged;

[0047] Further, such as Figure 2 As shown, a certain space is provided on the front side of the filter plate 34 for storing the blocked dirt. At this time, in order to ensure that all the dirt is discharged, the telescopic mechanism 26 is started. The telescopic mechanism 26 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism 26 drives the sewage discharge motor 27 to move, and the sewage discharge motor 27 drives the spiral shaft 28 to move, so that the spiral shaft 28 moves in the sewage discharge pipe 25, and then the lateral position of the spiral shaft 28 is adjusted to ensure that the spiral shaft 28 can discharge all the dirt;

[0048] Furthermore, when the filter plate 34 is cleaned and the filter plate 34 on the water inlet 23 side needs to be replaced, the conversion disk 31 is rotated again by the driving gear to complete the replacement of the filter plate 34, thereby satisfying the cleaning of the filter plate 34 while ensuring the sewage purification efficiency. At the same time, in order to ensure the shape of the expansion cavity 35 is restored, the gas is extracted from the expansion cavity 35 through the air pressure pipe 37 on the water inlet 23 side, and the expansion cavity 35 is restored;

[0049] Furthermore, in order to ensure that the water filter holes on the filter plate 34 are not blocked by dirt when the filter plate 34 is filtering sewage, during the filtering process, gas can be introduced into the expansion cavity 35 through the air pressure pipe 37, so that the expansion cavity 35 continuously squeezes the sewage to achieve the reverse flow of the sewage, and then the filter plate 34 is backwashed to ensure the filtering effect of the filter plate 34;

[0050] Furthermore, in order to improve the purification efficiency of sewage, the water purifier is introduced into the placement pipe 52, and the power mechanism is started. The power mechanism is preferably a servo motor, and the output shaft of the power mechanism starts to rotate, and the output shaft of the power mechanism drives the loading plate 54 to rotate, and the loading plate 54 drives the loading trough 55 to rotate, and the water purifier in the loading trough 55 is injected into the water inlet cavity 11 to purify the sewage;

[0051] like Figure 7 As shown, during the rotation of the conversion disk 31, the conversion disk 31 drives the impeller II 16 to rotate. When the impeller II 16 rotates, the sewage and the sewage agent are mixed and stirred, so that the sewage is purified. Since the conversion disk 31 does not rotate for a long time, an impeller I 15 is provided. When the impeller II 16 rotates, the impeller I 15 is driven to rotate by the torsion spring. The impeller I 15 drives the rotating column 14 to rotate. The rotating column 14 is in contact with the damping ring 13. The damping ring 13 provides damping for the rotation of the rotating column 14, so that the torsion spring accumulates force. Then, during the rotation period of the impeller I 15, the stored force of the torsion spring is gradually released to drive the impeller I 15 to rotate, so that the impeller I 15 mixes and stirs the sewage and the sewage agent, so that the sewage is purified.
