[0018] A first rotating shaft 2 is provided on the upper surface of the first tank body 13, and a first bevel gear 21 is fixedly installed on one side of the first rotating shaft 2, and second bevel gears 22 are meshed and connected on both sides of the first bevel gear 21. A second rotating shaft 23 is fixedly passed through the middle of the second bevel gear 22 located above, and the second rotating shaft 23 rotates and passes through the second bevel gear 22 located below. A third rotating shaft 24 is fixedly installed on the bottom end of the second bevel gear 22 located below, and the rotation of the third rotating shaft 24 passes through the first tank body 13. Several sleeves 25 are fixedly installed on the outside of the second rotating shaft 23 and the third rotating shaft 24, and several annularly evenly distributed stirring rods 26 are fixedly installed on the outside of the sleeves 25, and several annularly evenly distributed blades 4 are fixedly installed on the outside of each stirring rod 26.
[0019] A rotating rod 3 is rotated through the middle of the second tank body 17, and the rotating rod 3 is rotated to be clamped on the filter plate 18. A scraper 31 is fixedly installed on the outside of the rotating rod 3, and the scraper 31 is in contact with the filter plate 18. A slot 32 is provided on the side of the filter plate 18 away from the connecting pipe 16, and a collecting box 33 is provided below the slot 32. The inner length of the collecting box 33 is consistent with the length of the slot 32.
[0020] The diameter of the third rotating shaft 24 is larger than that of the second rotating shaft 23. The second rotating shaft 23 rotates through the third rotating shaft 24 and the second bevel gear 22 located below. The diameter of the sleeve 25 on the third rotating shaft 24 is larger than that of the sleeve 25 on the second rotating shaft 23. The length of each stirring rod 26 is the same.
[0021] The top end of the scraper 31 is inclined, so that the impurities falling on the scraper 31 directly slide onto the filter plate 18, and then the filter plate 18 is cleaned.
[0022] A conveying roller 5 is fixedly installed outside the second rotating shaft 23. The conveying roller 5 is located at the bottom of the second rotating shaft 23. By setting the conveying roller 5, the medicament at the bottom of the first tank body 13 can be conveyed upward, thereby preventing the medicament from precipitating at the bottom of the first tank body 13 and reducing the effect of the medicament.
[0023] An L-shaped plate 34 is fixedly installed at the bottom end of the filter plate 18. The right side of the L-shaped plate 34 is fixed to the inner wall of the second tank body 17. By setting the L-shaped plate 34, the collection box 33 placed in the second tank body 17 is supported.
[0024] A plurality of leakage holes 35 distributed in a rectangular array are formed through the bottoms of the L-shaped plate 34 and the collection box 33. By setting the leakage holes 35, the water entering the collection box 33 can be discharged, and only the impurities are retained in the collection box 33.
[0025] A support frame 6 is rotatably sleeved outside the first rotating shaft 2. The bottom end of the support frame 6 is fixed on the first tank body 13. The second rotating shaft 23 rotates through the upper part of the support frame 6, and the third rotating shaft 24 rotates through the lower part of the support frame 6. By setting the support frame 6, the first rotating shaft 2, the second rotating shaft 23, and the third rotating shaft 24 are supported, so that the first rotating shaft 2, the second rotating shaft 23, and the third rotating shaft 24 can work normally.
[0026] Working principle: In actual use, sewage is introduced into the first tank body 13 from the water inlet pipe 14. At the same time, the first motor on the first rotating shaft 2 and the second motor on the rotating rod 3 are started, so that the first motor drives the first rotating shaft 2 to rotate, thereby driving the first bevel gear 21 to rotate. As the first bevel gear 21 rotates, the second bevel gears 22 on both sides are driven to rotate. The second bevel gear 22 located above drives the second rotating shaft 23 and the stirring rods 26 and the blades 4 on the second rotating shaft 23 to rotate, and the second bevel gear 22 located below drives the third rotating shaft 24 and the stirring rods 26 and the blades 4 on the third rotating shaft 24 to rotate in the opposite direction, so as to mix the sewage and the medicament in the first tank body 13 more fully. At the same time, the large particles in the sewage are crushed more fully by the blades 4. Then, when mixing the sewage and the drug and crushing the impurities in the sewage, the valves on the water inlet pipe 14 and the connecting pipe 16 are closed. After mixing for a period of time, first open the valve on the connecting pipe 16, so that the crushed impurities and the mixed sewage are discharged into the second tank body 17 for filtration. Then, when all the sewage enters the second tank body 17, close the valve on the connecting pipe 16 and open the valve on the water inlet pipe 14 to inject sewage, and repeat the operation;
[0027] The sewage that enters the second tank body 17 retains impurities on the filter plate 18 through the filter plate 18, and the clear water directly falls to the bottom of the second tank body 17 from the filter plate 18 and is discharged from the water outlet pipe 19. Then, for the impurities on the filter plate 18, the rotation of the rotating rod 3 and the scraper 31 is driven by starting the second motor, and the scraper 31 scrapes the impurities on the filter plate 18 into the collection box 33, thereby preventing the filter plate 18 from being blocked by impurities and collecting the impurities at the same time.
[0028] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these modifications and variations.
