It further includes a bracket 9 which is arranged on the lower side of the outer arc surface of the cylinder 1. The filter is placed on the designated working position through the bracket 9. At this time, the external water supply device can be adjusted. The water source enters the inside of the cylinder 1 from the water inlet pipe 11. At this time, the water is filtered at the first stage by the coarse filter screen 44 and then flows into the space surrounded by the coarse filter screen 44 and the fine filter screen 45;

[0026] Filter mechanism 4: It includes a filter screen mounting frame 41, a reinforcing rod 42, a coarse filter screen frame 43, a coarse filter screen 44 and a fine filter screen 45. The filter screen mounting frame 41 is rotatably connected to the inside of the rotating groove 2. A fine filter screen 45 is fixedly connected between the upper and lower inner walls of the filter screen mounting frame 41. A reinforcing rod 42 is fixedly connected between the upper and lower inner walls of the filter screen mounting frame 41. The outer arc surfaces of the reinforcing rod 42 are all fixedly connected to the fine filter screen 45. The upper end of the reinforcing rod 42 and the filter screen mounting frame 41 are fixedly connected with a coarse filter screen 44 through a coarse filter screen frame 43;

[0027] Driving anti-blocking mechanism 5: It is arranged inside the cylinder body 1. The driving anti-blocking mechanism 5 is rotatably connected to the bottom cover 3. The driving anti-blocking mechanism 5 includes a driving rotating rod 51, a plugging frame 52, an upper scraping strip 53, a plugging slot 54 and a turntable 55. The driving rotating rod 51 is rotatably connected to the lower surface of the sealing cover. The lower end of the driving rotating rod 51 is fixedly connected with a plugging frame 52. The upper outer arc surface of the driving rotating rod 51 is provided with uniformly distributed upper scraping strips 53. The middle of the upper surface of the bottom cover 3 is rotatably connected with a turntable 55. The upper surface of the turntable 55 is provided with uniformly distributed plugging slots 54. The inside of the plugging slot 54 is plugged with the outer surface of the plugging frame 52. The middle of the coarse filter screen frame 43 is provided with uniformly distributed avoidance grooves 7. The inside of the avoidance grooves 7 is slidably connected with the outer surface of the plugging frame 52. The bottom end of the filter screen mounting frame 41 is provided with an upper arc-shaped rotating groove 6. The upper surface of the bottom cover 3 is provided with an arc-shaped round bar 10. The outer surface of the arc-shaped round bar 10 is rotatably connected with the inside of the upper arc-shaped rotating groove 6. It also includes an electric motor 14. The electric motor 14 is arranged in the middle of the upper end of the sealing cover. The output shaft of the electric motor 14 is fixedly connected with the upper end of the driving rotating rod 51. The input end of the electric motor 14 is electrically connected to the output end of the single-chip microcomputer 15. The height of the arc-shaped round bar 10 is relatively high, which can push the filter screen mounting frame 41 out by a certain height. The port where the lower end of the differential pressure pipe 13 communicates with the cylinder body 1 is located within the height difference. At this time, the single-chip microcomputer 15 can be adjusted. The electric motor 14 operates, and the output shaft of the electric motor 14 rotates, thereby driving the plugging frame 52 to rotate, and then driving the filter screen mounting frame 41 to rotate. At this time, the water inside the coarse filter screen 44 and the fine filter screen 45 is affected by centrifugal force. The pure water source flows into the interlayer between the fine filter screen 45 and the rotating groove 2 after being filtered twice by the fine filter screen 45. At this time, the external water return equipment is adjusted to discharge the water that has been filtered twice to complete the circulating water filtering operation. After operating like this for a period of time, the pressure gauge 18 can be observed. If the pressure gauge 18 shows that the pressure is too high, it means that there is too much coarse dirt between the upper side inside the cylinder body 1 and the upper coarse filter screen 44. At this time, the single-chip microcomputer 15 can be adjusted, and the electric motor 14 rotates at a low speed, thereby driving the rotating rod 51 to reduce the speed. The upper scraping strip 53 slowly scrapes the upper inner wall of the cylinder body 1. Manually open the flow control electric valve 16, and the coarse dirt is connected with the lower side inside the cylinder body 1 through the differential pressure pipe 13. At this time, the circulating operation is stopped, and the external sewage suction equipment sucks out these coarse dirt and fine dirt together, and then the water circulation operation can be carried out again.

[0028] The working principle of a circulating water filter provided by the present utility model is as follows: Place the filter on the designated work station through the bracket 9. At this time, the external water supply equipment can be adjusted. The water source enters the interior of the cylinder body 1 from the water inlet pipe 11. At this time, the water is subjected to the primary filtration of the coarse filter screen 44 and then flows into the space surrounded by the coarse filter screen 44 and the fine filter screen 45. At this time, the single-chip microcomputer 15 can be adjusted, and the electric motor 14 operates. The output shaft of the electric motor 14 rotates, driving the plug-in frame 52 to rotate, and then driving the filter screen mounting frame 41 to rotate. At this time, the water inside the coarse filter screen 44 and the fine filter screen 45 is affected by the centrifugal force. The pure water source flows into the interlayer between the fine filter screen 45 and the rotating groove 2 after passing through the secondary filtration of the fine filter screen 45. At this time, adjust the external water return equipment to discharge the water that has passed through the secondary filtration, completing the circulating water filtration operation. After operating for a period of time like this, the pressure gauge 18 can be observed. If the pressure gauge 18 shows excessive pressure, it means that there is too much coarse dirt between the upper side of the interior of the cylinder body 1 and the upper coarse filter screen 44. At this time, the single-chip microcomputer 15 can be adjusted, and the electric motor 14 rotates at a low speed, driving the rotating rod 51 to reduce the speed. The upper scraping strip 53 slowly scrapes the inner wall of the upper side of the cylinder body 1. Manually open the flow electric valve 16, and the coarse dirt is connected to the lower side of the interior of the cylinder body 1 through the differential pressure pipe 13. At this time, stop the circulating operation, and the external sewage suction equipment sucks out these coarse dirt and fine dirt together, and then the water circulation operation can be carried out again.

[0029] It should be noted that the single-chip microcomputer 14 disclosed in the above embodiments has a specific model of S7-200. The electric motor 14, the pressure gauge 18, and the flow electric valve 16 can be freely configured according to the actual application scenario. It is recommended to select the electric motor 14, the pressure gauge 18 is recommended to select the Y series reduction drive machine, the flow electric valve 16 is recommended to select the D971X model electric butt-welding butterfly valve. The single-chip microcomputer 14 controls the operation of the electric motor 14 and the flow electric valve 16 using the commonly used methods in the existing technology.

[0030] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present utility model, or directly or indirectly applied to other related technical fields, shall be equally included in the patent protection scope of the present utility model.
