Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] In one embodiment, see Figures 1-11A wastewater filtration device for water pollution treatment includes a filter box 1, a drain pipe 2 at the bottom of the filter box 1, the drain pipe 2 being vertically arranged on the left side of the bottom plate of the filter box 1, a feeding assembly 3 at the top of the filter box 1, and also includes a draining mechanism 4 and a stirring mechanism 5.

[0035] The drainage mechanism 4 includes a relief port 43 located on the side wall of the filter box 1. Inside the relief port 43 is a rotating disk 44 that can rotate in both directions. The rotating disk 44 is cylindrical and has a discharge port 45 on its side. The interior of the rotating disk 44 is hollow and can communicate with the outside through the discharge port 45. A sealing ring is provided on the inner ring of the relief port 43 so that there will be no water leakage between the rotating disk 44 and the relief port 43 when the rotating disk 44 is rotating.

[0036] The stirring mechanism 5 includes a rotating sleeve 17 vertically arranged on the right side of the bottom plate of the filter box 1. A vertically arranged sliding sleeve 18 is slidably connected above the rotating sleeve 17. A vertically arranged extension rod 19 is slidably connected above the sliding sleeve 18. The rotating sleeve 17, the sliding sleeve 18 and the extension rod 19 are all hollow structures. A stirring rod assembly 24 is arranged on the outside of the rotating sleeve 17, the sliding sleeve 18 and the extension rod 19. A lifting drive assembly 25 for adjusting the height of the sliding sleeve 18 and the extension rod 19 is arranged on the outside of the filter box 1.

[0037] In one embodiment, the stirring rod assembly 24 is provided with three sets evenly distributed relative to the axis of the rotating sleeve 17. The stirring rod assembly 24 includes a first stirring rod 20 disposed at the top, the upper end of which is rotatably connected to the upper part of the outer wall of the protruding rod 19. The lower end of the first stirring rod 20 is rotatably connected to the upper end of a second stirring rod 21. The lower end of the second stirring rod 21 is rotatably connected to the top of the outer wall of the sliding sleeve 18. A third stirring rod 22 is disposed below the second stirring rod 21, the upper end of which is rotatably connected to the upper part of the outer wall of the sliding sleeve 18. The position where the third stirring rod 22 connects to the sliding sleeve 18 is lower than the position where the second stirring rod 21 connects to the outer wall of the sliding sleeve 18. The lower end of the third stirring rod 22 is rotatably connected to the upper end of a fourth stirring rod 23. The lower end of the stirring rod 23 is rotatably connected to the outer wall of the rotating sleeve 17. Therefore, when the extension rod 19 moves up and down relative to the sliding sleeve 18, the angle between the first stirring rod 20 and the second stirring rod 21 changes, and the diameter of the first stirring rod 20 and the second stirring rod 21 extending outward changes, thereby changing the size of the stirring space. Similarly, the angle between the third stirring rod 22 and the fourth stirring rod 23 can be adjusted in the same way. That is to say, the stirring height and stirring diameter of the overall stirring mechanism 5 can be adjusted by adjusting the height of the sliding sleeve 18 and the extension rod 19. The first drive motor 26 is set on the rear side of the lower surface of the filter box 1. The output shaft of the first drive motor 26 is fixedly connected to the first bevel gear 27. The first bevel gear 27 meshes with the second bevel gear 28. The second bevel gear 28 is fixedly connected to the rotating sleeve 17.

[0038] In one embodiment, the lifting drive assembly 25 includes a first support plate 36 fixedly connected to the filter box 1. The first support plate 36 is vertically disposed on the outer side of the lower surface of the filter box 1, and two first support plates 36 are respectively disposed on the left and right sides of the rotating sleeve 17. A left-right oriented rotating shaft 42 is rotatably connected to the lower end of the first support plate 36. A first winding wheel 37 is disposed in the middle of the rotating shaft 42. A first pull rope 31 is wound around the outer side of the first winding wheel 37. The upper end of the first pull rope 31 is fixedly connected to the left and right sides. The first partition 29 is oriented towards the middle. The left and right ends of the first partition 29 are fixedly connected to the lower inner wall of the extension rod 19. The second winding wheel 38 is provided on the left and right sides of the rotating shaft 42. The second winding wheel 38 is wound with a second pull rope 33. The free end of the second pull rope 33 is fixedly connected to the left and right sides of the second partition 32. The left and right ends of the second partition 32 are fixedly connected to the lower inner wall of the sliding sleeve 18. A through hole is provided in the middle of the second partition 32 so that the first pull rope 31 can pass through the through hole. The diameter of the first winding wheel 37 is twice the diameter of the second winding wheel 38, causing the extension rod 19 to move at twice the speed of the sliding sleeve 18. This ensures that when the sliding sleeve 18 reaches its bottom, the extension rod 19 will also reach its bottom, achieving synchronous movement. This also makes the angle change speed of the outer stirring rod assembly 24 more similar, making the entire device more convenient to use. To ensure the first and second pull ropes 31 and 33 remain taut, a retaining ring 35 can be provided at the bottom of the rotating sleeve 17, a first spring 30 can be provided between the end of the extension rod 19 and the second partition 32, and a second spring 34 can be provided between the sliding sleeve 18 and the retaining ring 35. This results in the sliding sleeve 18 having an upward tendency relative to the rotating sleeve 17, and the extension rod 19 having an upward tendency relative to the sliding sleeve 18. Furthermore, a second drive motor 39 is installed in the middle of the first support plate 36 on the right side. The output shaft of the second drive motor 39 is fixedly connected to a third bevel gear 40, which meshes with a fourth bevel gear 41. The fourth bevel gear 41 is fixedly connected to the end of the rotating shaft 42. The second drive motor 39 can rotate the rotating shaft 42 through gear transmission, thereby enabling the extension rod 19 and the sliding sleeve 18 to move synchronously.

[0039] In one embodiment, second support plates 46 are provided on both sides of the clearance opening 43. The second support plates 46 are fixedly connected to the outside of the left side wall of the filter box 1, and are arranged in a left-right orientation on the front and rear sides of the clearance opening 43. A front-rear orientation support shaft 47 is rotatably connected to the left end of the second support plate 46. A rotating disk 44 is fixedly connected to the middle of the support shaft 47. The rotating disk 44 is a hollow structure, and a reinforcing rib 51 extending outward can be provided in the middle of the support shaft 47. The end of the reinforcing rib 51 is fixed. The inner wall of the rotating disk 44 is connected to make the connection between the rotating disk 44 and the support shaft 47 more stable. A third drive motor 50 is set in the middle of the second support plate 46 on the front side. The output shaft of the third drive motor 50 is fixedly connected to the fifth bevel gear 49. The fifth bevel gear 49 meshes with the sixth bevel gear 48. The sixth bevel gear 48 is fixedly connected to the front end of the support shaft 47. Therefore, the third drive motor 50 can make the support shaft 47 rotate through gear transmission, thereby making the rotating disk 44 rotate around the axis of the support shaft 47.

[0040] In one embodiment, the feeding assembly 3 includes a feeding port 6 disposed on the top of the filter box 1. Third support plates 7 are vertically disposed on the left and right sides of the feeding port 6 and fixedly connected to the top of the filter box 1. A horizontal bar 9 oriented left and right is rotatably connected to the upper end of the third support plate 7. The end of the horizontal bar 9 near the center of the filter box 1 is fixedly connected to the left and right ends of a screening box 8. The screening box 8 has an open top and filter holes at the bottom. The left end of a left-right oriented drive shaft 13 is rotatably connected to the middle of the third support plate 7. A fourth drive motor 10 is disposed below the third support plate 7, and the output shaft of the fourth drive motor 10 is fixed. The seventh bevel gear 11 is connected to the eighth bevel gear 12, which is fixedly connected to the left side of the drive shaft 13. A drive disk 16 is fixedly connected to the right end of the drive shaft 13. The lower end of the support rod 14 is rotatably connected to the outer right edge of the drive disk 16. The upper end of the support rod 14 is rotatably connected to the front end of the deflection plate 15. The rear end of the deflection plate 15 is fixedly connected to the right end of the drive shaft 13. The fourth drive motor 10 can make the drive shaft 13 rotate through gear transmission. The drive shaft 13 causes the crossbar 9 to swing back and forth through the cooperation of the support rod 14 and the deflection plate 15, thereby causing the screening box 8 to swing back and forth.

[0041] In this embodiment, a throttling valve is installed inside the drain pipe 2. Therefore, at the initial stage of use, the throttling valve of the drain pipe 2 needs to be closed, and the third drive motor 50 needs to be started. The third drive motor 50 drives the rotating disk 44 to rotate counterclockwise, so that the discharge port 45 of the rotating disk 44 faces to the left and is located outside the filter box 1. At this time, the inside of the filter box 1 is sealed, and the sewage to be treated can be poured into the filter box 1 through the feed port 6. After the sewage is poured in, the first drive motor 26 can be started. The first drive motor 26 causes the rotating sleeve 17, the sliding sleeve 18 and the extension rod 19 to rotate through gear transmission, so that the stirring rod assembly 24 stirs the liquid inside the filter box 1. During the stirring process, the second drive motor 39 is started. The second drive motor 39 rotates the shaft 42 through gear transmission, thereby adjusting the height of the sliding sleeve 18 and the extension rod 19, and thus adjusting the working depth of the stirring rod assembly 24. At this time, the chemical reagents for sewage treatment can be poured into the screening box 8. The fourth drive motor 10 is started, and the fourth drive motor 10 drives the screening box 8 to shake back and forth. The chemical reagents fall into the interior of the filter box 1. After the sewage is treated, flocculent precipitates will be generated. At this time, the first drive motor 26 can be stopped, and the second drive motor 39 is started in reverse, so that the sliding sleeve 18 and the extension rod 19 are in the lowest position, which facilitates the deposition of flocculent precipitates at the bottom of the filter box 1.

[0042] After sedimentation is completed in filter box 1, the third drive motor 50 is started. The third drive motor 50 causes the rotating disk 44 to rotate clockwise through gear transmission, thereby causing the discharge port 45 to rotate into the interior of filter box 1. When the height of the discharge port 45 is lower than the water level inside filter box 1, the clarified liquid above filter box 1 will enter the rotating disk 44. The height of the discharge port 45 can be adjusted by adjusting its orientation, which means adjusting the water body at different heights in filter box 1 for discharge. During the discharge process, if the liquid inside the rotating disk 44 is full, it can be rotated counterclockwise for real-time discharge, so that the clarified liquid in the upper layer of filter box 1 can be discharged effectively.

[0043] This invention relates to a wastewater filtration device for water pollution treatment. By setting a rotating disk 44 with a discharge port 45 and free rotation inside the filter box 1, liquids at different heights in the filter box 1 can be effectively discharged, thereby preventing the leakage of sediments below when the clarified liquid is discharged, and improving the wastewater filtration effect.

[0044] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
