The output end of the motor 18 is fixedly connected to a rotating shaft 19. The bottom of the outer wall of the rotating shaft 19 is fixedly connected to a cross bar 20. A brush plate 21 is fixedly connected to one side of the cross bar 20. The outer side of the brush plate 21 is provided with bristles, and the bristles are in contact with the inside of the filter 2. The bottom of the outer wall of the barrel body 1 is fixedly connected to a mounting plate 31. A water pump 23 is mounted on the top surface of the mounting plate 31. The output end of the water pump 23 is fixedly connected to a delivery pipe 24. One end of the delivery pipe 24 is fixedly connected to a water outlet plate 25. The water outlet plate 25 is fixedly connected to the bottom of the inner wall of the barrel body 1, and the inner wall of the water outlet plate 25 is in contact with the outer side of the filter 2. A cavity is provided inside the water outlet plate 25, and a water outlet hole is provided on the inner wall of the water outlet plate 25, and the water outlet hole is connected to the cavity.
[0038] The driving motor 18 can drive the rotating shaft 19, the cross bar 20 and the brush plate 21. At this time, the bristles can be used to clean the filter 2. Then, the water pump 23 is driven to transport clean water into the water outlet plate 25, and the water is sprayed out from the inside of the water outlet hole. At this time, backflushing can be performed to improve the cleaning effect of the filter 2.
[0039] Reference Figure 1 、 Figure 5 and Figure 6 The bottom of the inner wall of the barrel body 1 is fixedly connected to a bracket 22, which is rotatably connected to the rotating shaft 19. The bottom and bottom of the filter screen 2 are respectively provided with a bottom plate 26 and a pressure plate 27. The bottom plate 26 and the pressure plate 27 are both installed on the inner wall of the barrel body 1, and the top surface of the pressure plate 27 is lower than the height of the water inlet pipe 3.

[0040] The rotating shaft 19 can be supported by the bracket 22, and the filter screen 2 can be supported and fixed by the bottom plate 26 and the pressure plate 27. When cleaning is completed, the sewage can be discharged from the sewage pipe 28 by opening the sewage valve 29.
[0041] Working principle: when in use, close the second valve 6 and the fourth valve 12, open the first valve 5 and the third valve 11, and connect the water inlet pipe 3 and the water outlet pipe 10 with the heating equipment. At this time, water can enter the bottom of the barrel body 1 along the water inlet pipe 3. At this time, the water will enter the outlet pipe 10 through the filter screen 2 to achieve water filtration. When the filter screen 2 needs to be cleaned, close the first valve 5 and the third valve 11, open the second valve 6 and the fourth valve 12, and water can enter the outlet pipe 10 along the water inlet pipe 3, the guide pipe 4, the connecting pipe 7, the diversion pipe 8 and the fixed pipe 9, thereby preventing water from entering the interior of the barrel body 1, and the filter plate 32 inside the diversion pipe 8 can filter the water. At this time, the filter screen 2 can be cleaned. When cleaning the filter screen 2, first connect the input end of the water pump 23 with the clean water, and then drive the water pump 23 to send the clean water along the delivery pipe 24 into the water outlet plate 25. The clean water enters the cavity inside the water outlet plate 25 and is sprayed out from the water outlet hole. At this time, the driving motor 18 drives the rotating shaft 19, the cross bar 20 and the brush plate 21 to rotate. The brush plate 21 can be used to clean the filter 2 mechanically, and the spraying of clean water can realize the backwash of the filter 2, thereby cleaning the filter 2. After cleaning, open the drain valve 29 to discharge the sewage from the drain pipe 28. Finally, close the second valve 6, the fourth valve 12 and the drain valve 29, open the third valve 11 and the first valve 5, and allow water to enter the barrel body 1 again. When it is necessary to clean the filter plate 32 inside the diverter pipe 8, the connecting pipe 7 and the diverter pipe 8 are separated by rotating the first clamping ring 13, and then the second clamping ring 15 is rotated to separate the diverter pipe 8 and the fixed pipe 9. At this time, the diverter pipe 8 can be removed from the device, and then the sealing cover 17 is rotated to remove it from the diverter pipe 8. At this time, the filter plate 32 is rinsed.
