Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a flocculation device for turbid circulating water. Background Technology

[0002] Turbid circulating water is a type of wastewater containing a high concentration of solid particles. It needs to be treated before it can be reused. Suspended solid particles must first be removed through physical or chemical means, and then it must undergo a treatment process similar to that of clean circulating water. Turbid circulating water must be treated before it can be reused, otherwise it will cause significant environmental pollution.

[0003] Patent CN220788210U discloses an industrial circulating water filtration device. A first drive motor rotates a crankshaft, which in turn rotates a movable plate and a connecting plate around a fixed rod. This stirrer agitates the circulating water in the mixing tank, facilitating the mixing and dissolution of added additives. The additives then readily combine with particulate matter in the circulating water, achieving flocculation and sedimentation, thus reducing the content of particulate matter and microorganisms in the circulating water. A second drive motor then rotates a rotating shaft, which in turn rotates a support frame. This support frame, along with the movable frame and filter plate, filters the circulating water introduced into the fixed frame, separating the flocculants and improving the purity of the circulating water.

[0004] The drawback of the above solution is that the cleaning efficiency of turbid water decreases due to the accumulation of solid impurities and flocculation sediment inside the equipment, requiring manual cleaning, which is inconvenient. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a flocculation device for turbid circulating water to solve the problems mentioned in the background. This invention has a novel structure. The flocculant is evenly sprinkled into the mixing tank and mixed with the turbid water through the drive component. The agitator rotates synchronously to ensure uniform mixing. In conjunction with the filter tank, the turbid water is filtered. The drive component also cleans the surface of the filter plate at the same time, thereby ensuring that the equipment can operate continuously and efficiently.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flocculation device for turbid circulating water, comprising a mixing tank, an annular filter plate fixed to the top of the mixing tank, a disc rotatably mounted on the inner ring of the annular filter plate, a drive shaft fixed to the top of the disc, and the bottom of the drive shaft rotatably mounted on the inner wall of the bottom of the mixing tank. A storage cavity is provided inside the disc, and an outlet is provided at the bottom of the outer ring of the storage cavity. Three sets of stirring frames are fixed to the surface of the drive shaft, and a float ring is provided at the bottom of each stirring frame, with the inner ring of the float ring slidably fitted onto the drive shaft. An overflow trough is provided on the side plate of the mixing tank, and a filter tank is fixed to the bottom of the mixing tank at the overflow trough. A filter plate is fixed inside the filter tank, and a drain pipe is provided on one side of the bottom of the filter tank. A drive assembly is provided at the top of the mixing tank, the drive assembly including sweeping plates. Sweeping plates are symmetrically fixed through the top of the disc and slide along the surface of the annular filter plate.

[0007] Furthermore, the drive assembly also includes a circular plate, the top of the drive shaft is fixed with the circular plate, a first connecting rod is rotatably mounted at the eccentric top of the circular plate, a push plate is slidably mounted on the surface of the filter plate, and a vertical shaft is fixed at the top of the push plate. The other end of the first connecting rod is rotatably connected to a second connecting rod, and the other end of the second connecting rod is rotatably connected to the top of the vertical shaft.

[0008] Furthermore, a transmission belt is mounted on the surface of the drive shaft, a drive motor is fixed on one side of the outer wall of the mixing tank, and the output end of the drive motor is fixedly connected to the pulley at the other end of the transmission belt.

[0009] Furthermore, a circular ring plate is provided at the bottom of the disk on the outside of the storage cavity. A retaining ring is fixed on the side of the circular ring plate near the outlet, and the retaining ring slides along the outside of the storage cavity. Return springs are fixed at equal intervals on the inner wall of the storage cavity, and the bottom of the return springs is fixedly connected to the circular ring plate.

[0010] Furthermore, a scraper is rotatably mounted on the surface of the drive shaft near the storage cavity, and the scraper penetrates into the interior of the storage cavity and slides in contact with the inner walls on both sides of the storage cavity.

[0011] Furthermore, vertical rods are fixed at equal intervals at the bottom of the annular plate, and a sliding sleeve is fixed at the bottom of the vertical rod, the sliding sleeve being slidably fitted onto the float ring.

[0013] Furthermore, a baffle is sealed and installed on the outside of the mixing tank at the bottom of the annular filter plate, and a water-blocking ring is fixed inside the mixing tank at the bottom of the annular filter plate.

[0014] The beneficial effects of this utility model are:

[0015] 1. This utility model can periodically open the baffle to clean the solid impurities accumulated on the annular filter plate out of the mixing tank, and the water-blocking ring at the bottom of the annular filter plate can block the turbid water flowing down from the annular filter plate to prevent the turbid water from flowing directly out of the overflow tank.

[0016] 2. This utility model uses a drive assembly to move the pusher plate back and forth along the surface of the filter plate, thereby pushing the flocculated sediment on the surface of the filter plate out of the slag discharge trough and maintaining the permeability of the filter plate.

[0017] 3. As turbid water enters the mixing tank, the float ring moves upward due to buoyancy, the vertical rod pushes open the circular plate, and at the same time, the retaining ring opens the outlet of the storage chamber.

The rotation of the drive shaft drives the disc to rotate, making the flocculant distribution more uniform and further improving the uniformity of the mixing of flocculant and turbid water. The scraper slides along the inner walls on both sides of the storage chamber to clean the adhering flocculant.

[0018] 4. This utility model uses a drive motor and a transmission belt to drive the drive shaft to rotate, the circular plate to rotate synchronously, and the first and second connecting rods to push the push plate to slide along the surface of the filter plate to clean the surface of the filter plate. The rotation of the drive shaft drives the sweeping plate to slide along the surface of the annular filter plate to prevent solid impurities from accumulating on the annular filter plate. The stirring frame stirs and mixes the turbid water and flocculant inside the mixing tank.

[0019] 5. Compared with the prior art, this utility model uses a drive component to evenly sprinkle flocculant into the mixing tank and mix it with turbid water. The agitator rotates synchronously to ensure uniform mixing. In conjunction with the filtration tank, the turbid water is filtered. The drive component also cleans the surface of the filter plate at the same time, thereby ensuring that the equipment can operate continuously and efficiently. Attached Figure Description

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] Please see Figures 1 to 6 This utility model provides a technical solution: a flocculation device for turbid circulating water, including a mixing tank 1. An annular filter plate 11 is fixed to the top of the mixing tank 1. A disc 4 is rotatably mounted on the inner ring of the annular filter plate 11. A drive shaft 14 is fixed to the top of the disc 4. The bottom of the drive shaft 14 is rotatably mounted on the inner wall of the bottom of the mixing tank 1. A storage cavity 43 is provided inside the disc 4, and an outlet 46 is opened at the bottom of the outer ring of the storage cavity 43. Three sets of stirring frames 15 are fixed to the surface of the drive shaft 14. A float ring 5 is provided at the bottom of the stirring frame 15, and the inner ring of the float ring 5 is slidably sleeved on the drive shaft 14. An overflow trough 12 is opened on the side plate of the mixing tank 1, and a filter tank 2 is fixed at the bottom of the overflow trough 12. The filter tank 2 has a filter plate 22 fixed inside, and a drain pipe 21 is provided on one side of the bottom of the filter tank 2. The top of the mixing tank 1 is provided with a drive assembly 3, which includes a sweeping plate 38. The drive shaft 14 passes through the top of the disc 4 and the sweeping plate 38 is symmetrically fixed thereon. The sweeping plate 38 slides along the surface of the annular filter plate 11. When using the device, turbid water is sent into the mixing tank 1 from the top. The solid impurities inside the turbid water are filtered through the annular filter plate 11. Then, the cover plate 41 on the disc 4 is opened, and flocculant is added into the storage cavity 43. While the drive assembly 3 drives the agitator 15 to rotate, the flocculant is evenly sprinkled on the bottom of the mixing tank 1. As turbid water is added, the turbid water that exceeds the overflow tank 12 enters the filter tank 2 and is filtered by the filter plate 22 for flocculation and sedimentation.

[0029] In this embodiment, the drive assembly 3 further includes a circular plate 33. The top of the drive shaft 14 is fixed with the circular plate 33. A first connecting rod 34 is rotatably mounted at the eccentric top of the circular plate 33. A push plate 31 is slidably mounted on the surface of the filter plate 22, and a vertical shaft 32 is fixed to the top of the push plate 31. The other end of the first connecting rod 34 is rotatably connected to a second connecting rod 35, and the other end of the second connecting rod 35 is rotatably connected to the top of the vertical shaft 32. A transmission belt 36 is mounted on the surface of the drive shaft 14. A drive motor 37 is fixed to one side of the outer wall of the mixing tank 1, and the output end of the drive motor 37 is connected to the pulley at the other end of the transmission belt 36. A scraper 44 is rotatably mounted on the surface of the drive shaft 14 near the storage cavity 43. The scraper 44 penetrates the interior of the storage cavity 43 and slides in contact with the inner walls on both sides of the storage cavity 43. The drive motor 37 and the transmission belt 36 work together to drive the drive shaft 14 to rotate, and the circular plate 33 rotates synchronously. The first connecting rod 34 and the second connecting rod 35 work together to push the push plate 31 to slide along the surface of the filter plate 22 to clean the surface of the filter plate 22. The rotation of the drive shaft 14 drives the sweeping plate 38 to slide along the surface of the annular filter plate 11 to prevent solid impurities from accumulating on the annular filter plate 11. The agitator 15 stirs and mixes the turbid water and flocculant inside the mixing tank 1.

[0030] In this embodiment, a circular ring plate 42 is provided at the bottom of the disc 4 outside the storage cavity 43. A retaining ring 47 is fixed on the side of the circular ring plate 42 near the outlet 46, and the retaining ring 47 slides along the outside of the storage cavity 43. Return springs 45 are fixed at equal intervals on the inner wall of the storage cavity 43, and the bottom of the return springs 45 is fixedly connected to the circular ring plate 42. Vertical rods 52 are fixed at equal intervals on the bottom of the circular ring plate 42, and a sliding sleeve 51 is fixed to the bottom of the vertical rods 52. The sliding sleeve 51 is slidably sleeved on the float ring 5. As turbid water enters the mixing tank 1, the float ring 5 moves upward due to the buoyancy of the water, and the vertical rods 52 push open the circular ring plate 42, simultaneously blocking the flow of water. Ring 47 opens the outlet 46 of storage chamber 43. The outlet 46 contains flocculant. Under the force of gravity and the push of scraper 44, the flocculant is sent out from the opening of the ring plate 42 and falls into the bottom of the mixing tank 1. The rotation of drive shaft 14 drives the disk 4 to rotate, making the flocculant distribution more uniform and further improving the uniformity of mixing of flocculant and turbid water. The scraper 44 slides along the inner walls of both sides of storage chamber 43 to clean the adhering flocculant. The scraper 44 is rotatably mounted on drive shaft 14 and can be fixedly connected to the annular filter plate 11. Therefore, the rotation of disk 4 driven by drive shaft 14 will not affect the position of scraper 44.

[0031] In this embodiment, a slag discharge groove 23 is provided on the surface of the filter plate 22 at the outer end of the filter pool 2. The push plate 31 is driven by the drive component 3 to move back and forth along the surface of the filter plate 22, thereby pushing the flocculated sediment on the surface of the filter plate 22 out of the slag discharge groove 23 and maintaining the permeability of the filter plate 22.

[0032] In this embodiment, a baffle 13 is sealed and installed on the outside of the mixing tank 1 at the bottom of the annular filter plate 11, and a water-blocking ring 16 is fixed inside the mixing tank 1 at the bottom of the annular filter plate 11. The baffle 13 can be opened periodically to clean the solid impurities accumulated on the annular filter plate 11 out of the mixing tank 1. The water-blocking ring 16 at the bottom of the annular filter plate 11 blocks the turbid water flowing down from the annular filter plate 11, preventing the turbid water from flowing directly out of the overflow tank 12.

[0033] When using the device, turbid water is fed into the mixing tank 1 from the top. Solid impurities inside the turbid water are filtered through the annular filter plate 11. Then, the cover plate 41 on the disc 4 is opened, and flocculant is added into the storage chamber 43. The drive motor 37 and transmission belt 36 work together to drive the drive shaft 14 to rotate, and the disc 33 rotates synchronously. The first connecting rod 34 and the second connecting rod 35 work together to push the push plate 31 to slide along the surface of the filter plate 22, cleaning the surface of the filter plate 22. The rotation of the drive shaft 14 drives the sweeping plate 38 to slide along the surface of the annular filter plate 11, preventing solid impurities from accumulating on the annular filter plate 11. The stirring frame 15 stirs and mixes the turbid water and flocculant inside the mixing tank 1. As turbid water enters the mixing tank 1, the float ring 5 moves upward due to the buoyancy of the water, and the vertical rod 52 pushes open the annular plate 42. The retaining ring 47 opens the outlet 46 of the storage chamber 43. The outlet 46 contains flocculant. Under the force of gravity and the push of the scraper 44, the flocculant is sent out from the opening of the ring plate 42 and falls into the bottom of the mixing tank 1. The rotation of the drive shaft 14 drives the disc 4 to rotate, making the flocculant distribution more uniform and further improving the uniformity of the mixing of flocculant and turbid water. The scraper 44 slides along the inner walls of both sides of the storage chamber 43 to clean the adhering flocculant. The scraper 44 is rotatably mounted on the drive shaft 14 and can be fixedly connected to the annular filter plate 11. Thus, the rotation of the disc 4 driven by the drive shaft 14 will not affect the position of the scraper 44. As turbid water is added, the turbid water that exceeds the overflow tank 12 enters the filter tank 2 and is filtered by the filter plate 22 for flocculant sedimentation.

It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
