[0020] Example 2

[0021] On the basis of Example 1, Figure 1-Figure 3 As shown, the filter assembly 2 includes an upper filter tube 21, a liquid inlet pipe 211 is arranged on the side of the upper filter tube 21, the upper filter tube 21 is sleeved on the lower filter tube 22, the bottom of the lower filter tube 22 is fixedly connected to the liquid inlet 11 of the circulating pump 1 through a flange, and a filter cover 23 is arranged on the top of the lower filter tube 22. A rotating shaft 24 is rotatably arranged on the top of the upper filter tube 21, and a cleaning ring 25 is fixedly arranged at one end of the bottom of the rotating shaft 24, and the cleaning ring 25 is sleeved on the outer surface of the filter cover 23. The other end of the rotating shaft 24 extends out of the top of the upper filter tube 21, and a bevel gear 26 is arranged on the part of the rotating shaft 24 extending out of the upper filter tube 21. A fixing plate 23 is arranged on the top of the upper filter tube 21. 7. A rotating shaft 28 is horizontally rotatably arranged in the fixed plate 1 27. A bevel gear 29 and a bevel gear 30 are respectively arranged at the left and right ends of the rotating shaft 28. The bevel gear 1 26 is meshed with the bevel gear 2 29. A fixed plate 2 31 is fixedly arranged on the side wall of the upper filter tube 21. A rotating shaft 32 is vertically rotatably arranged on the fixed plate 2 31. A bevel gear 4 33 and a bevel gear 5 34 are respectively arranged at the top and bottom of the rotating shaft 32. The bevel gear 30 is meshed with the bevel gear 4 33. A rotating shaft 35 is horizontally rotatably arranged on the inner wall of the lower filter tube 22. An impeller 36 is arranged on the rotating shaft 35. A bevel gear 6 37 is arranged on the portion of the rotating shaft 35 extending out of the lower filter tube 22. The bevel gear 6 37 is meshed with the bevel gear 5 34.

[0022] The working principle and beneficial effects of the above technical solution are as follows: the liquid inlet pipe 211 and the liquid inlet port 11 are tightly connected by a flange, and the liquid enters the upper filter tube 21 from the liquid inlet pipe 21, and the upper filter tube 21 is vertically sleeved on the lower filter tube 22, and the upper filter tube 21 and the lower filter tube 22 are fixedly connected horizontally by bolts, and the liquid entering the upper filter tube 21 enters the lower filter tube 22 through the filter cover 23, and the filter cover 23 filters the large particles of impurities in the liquid and leaves them on the filter cover 23, and the rotation of the rotating shaft 24 drives the cleaning ring 25 to rotate synchronously, and the cleaning ring 25 rotates along the outer surface of the filter cover 23, and the cleaning ring 25 cleans the impurities remaining on the surface of the filter cover 23 when rotating, and the scraped impurities fall to the top of the lower filter tube 22 and accumulate. When maintenance, the bolts outside the upper filter tube 21 are removed, and the connection between the upper filter tube 21 and the lower filter tube 22 is opened, and the accumulated impurities are removed. The impurities are cleaned to ensure the normal filtration of the filter assembly 2 and prevent blockage. The filtered liquid falls downward through the filter lower tube 22. During the falling process of the liquid, it impacts the impeller 36, and the potential energy of the liquid is converted into kinetic energy of the impeller 36. The impeller 36 rotates to drive the rotating shaft 35 to rotate. When the rotating shaft 35 rotates, the meshing of the bevel gear 6 37 and the bevel gear 5 34 drives the rotating shaft 32 on the fixed plate 21 to rotate. When the rotating shaft 32 rotates, the meshing of the bevel gear 4 33 and the bevel gear 3 30 drives the rotating shaft 28 on the fixed plate 1 27 to rotate. When the rotating shaft 28 rotates, the meshing of the bevel gear 29 and the bevel gear 1 26 drives the rotating shaft 1 24 and the cleaning ring 25 to rotate. The cleaning ring 25 rotates and cleans the filter cover 23, which reasonably utilizes the potential energy of the liquid, saves resources and cleans the filter cover 23 at the same time.

[0023] Example 3

[0024] On the basis of Example 2, Figure 1-Figure 3As shown, the flow rate detection includes a liquid passing pipe 41, and the liquid passing pipe 41 is fixedly connected to the liquid outlet 12 of the circulating pump 1 through a flange. A fixed bin 42 is fixedly arranged at the bottom of the liquid passing pipe 41, and a motor 43 is fixedly arranged in the fixed bin 42. Two rotating shafts 44 are rotatably arranged at the bottom of the fixed bin 42, and a rotating sleeve 45 is arranged on the top of the rotating shaft 44. The rotating sleeve 45 is rotatably arranged in the fixed bin 42, and a sealing ring 46 is arranged between the rotating sleeve 45 and the fixed bin 42. A screw 47 is rotatably arranged in the rotating sleeve 45 through a thread, and a liquid passing bin 48 is fixedly arranged on the top of the screw 47. Conical filter covers 49 are provided at both ends, a flow rate detector 50 is fixedly provided in the liquid storage bin 48, a rotating rod 51 is horizontally rotatably provided in the fixed bin 42, a bevel gear seven 52 is provided at the output end of the motor 43, a bevel gear eight 53 is provided in the middle of the rotating rod 51, a bevel gear nine 54 and a bevel gear ten 55 are respectively provided at both ends of the rotating rod 51, the bevel gear seven 52 is meshed with the bevel gear ten 55 for transmission, a bevel gear ten 55 one and a bevel gear ten 55 two are respectively provided on the two rotating shafts 44, the bevel gear ten 55 one is meshed with the bevel gear nine 54 for transmission, and the bevel gear ten 55 two is meshed with the bevel gear ten 55 for transmission.

[0025] The working principle and beneficial effects of the above technical solution are as follows: the liquid flowing out from the liquid outlet 12 of the circulation pump 1 flows into the liquid pipe 41, and the liquid flow entering the liquid pipe 41 passes through the flow rate detector 50 in the liquid bin 48, and the flow rate detector 50 detects the flow rate. The conical design of the conical filter cover 49 at both ends of the liquid bin 48 reduces the obstruction to the liquid flow rate, and the filter holes opened on the conical filter cover 49 further reduce the obstruction to the liquid flow rate. The motor 43 drives the bevel gear seven 52 to rotate, and the bevel gear seven 52 drives the rotating rod 51 to rotate by meshing with the bevel gear eight 53, and the rotating rod 51 drives the bevel gear thereon The wheel nine 54 and the bevel gear ten 55 rotate, and the bevel gear nine 54 and the bevel gear ten 55 respectively drive the two rotating shafts 44 to rotate synchronously by meshing with the bevel gear ten 55 one and the bevel gear ten 55 two. When the rotating rod 51 rotates, the rotating sleeve 45 thereon is driven to rotate at a speed. When the rotating sleeve 45 rotates, the screw 47 in the rotating sleeve 45 is lifted and lowered in the rotating sleeve 45 under the action of gravity. The two screws 47 are lifted and lowered synchronously, driving the liquid storage bin 48 thereon to lift and lower, thereby adjusting the height position of the liquid storage bin 48 in the filter tube, which is convenient for flow rate detection at multiple positions, thereby making the flow rate detection more accurate.
