Description

Technical Field

[0001] This utility model relates to the field of inclined tube sedimentation tank flushing technology, and more specifically, to a high-efficiency air flushing device for inclined tube sedimentation tanks based on directional cyclone disturbance. Background Technology

[0002] Inclined tube sedimentation tanks are a type of high-efficiency solid-liquid separation equipment used in wastewater treatment, tap water purification, and other fields. The core of the equipment is to set up inclined tube components in the sedimentation tank, which greatly shortens the settling distance of suspended particles in the water and accelerates the settling process, thereby achieving a solid-liquid separation effect of "small footprint and high treatment efficiency". It is widely used in municipal sewage secondary sedimentation tanks, tap water plant clarification tanks, industrial wastewater pretreatment and other scenarios.

[0003] A search revealed that Chinese Patent CN221752394U discloses an air flushing device for an inclined tube sedimentation tank, comprising a Roots blower, an air supply pipe, and an air pipeline. The Roots blower is connected to the air pipeline through the air supply pipe. The air pipeline is located below the inclined tube of the inclined tube sedimentation tank. The air pipeline includes a main air pipe, an air connecting pipe, and several air branch pipes. The several air branch pipes are arranged parallel to each other, and one end of each air branch pipe is connected to the main air pipe. This utility model adds an air pipeline below the inclined tube, which can perform air flushing on the inclined tube.

[0004] When the above-mentioned air flushing device is in use, the two ends of the air branch pipe are fixedly connected to the air main pipe and the air connecting pipe, respectively. It is inconvenient to adjust the length of the air branch pipe. The width of the inclined tube sedimentation tank varies in different scenarios. The fixed length of the air branch pipe cannot be flexibly adjusted according to the width of the tank. When the branch pipe is shorter than the tank length, there will be no airflow coverage at the far end of the tank, forming a flushing blind zone. When the branch pipe is longer than the tank length, the two ends of the air branch pipe cannot be accurately connected to the air main pipe and the air connecting pipe, resulting in a limited range of applications. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a high-efficiency air flushing device for inclined tube sedimentation tank based on directional cyclone disturbance, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency air flushing device for inclined tube sedimentation tank based on directional cyclone disturbance, comprising a main pipe and a connecting pipe, wherein the connecting pipe is located on one side of the main pipe, and side pipes are fixedly connected to the opposite sides of the main pipe and the connecting pipe, and multiple branch pipes are arranged between the main pipe and the connecting pipe, each of the multiple branch pipes having multiple air distribution holes, and first connecting plates are fixedly connected to both ends of the multiple branch pipes and one end of the multiple side pipes, and the multiple first connecting plates are fixedly connected to each other by bolts, and a tapered pipe is fixedly connected to the front end of the main pipe, and a second connecting plate is fixedly connected to the front end of the tapered pipe.

[0007] Furthermore, each end of the plurality of branch pipes is provided with a gasket, and one side of each gasket is fixedly connected to a first connecting plate on the plurality of branch pipes.

[0008] As can be seen, in the above technical solution, the gasket can improve the sealing between the branch pipe and the side pipe.

[0009] Furthermore, the multiple air distribution holes are arranged in a double-row symmetrical structure on the sidewalls of the multiple branch pipes, and the opening angle of the air distribution holes is 45 degrees downwards from the vertical direction.

[0010] Furthermore, the diameter of the end of the tapered tube near the main pipe is smaller than that of the end of the tapered tube near the second connecting plate.

[0011] As can be seen, the above technical solution ensures that the air pressure in each branch pipe is balanced, effectively avoiding the problem of reduced flushing intensity caused by insufficient air volume in the far-end branch pipes of the pool.

[0012] Furthermore, both the main pipe and the connecting pipe are provided with two support components. Each of the multiple support components includes a fixing plate, a U-shaped plate, a lead screw, two nuts, and two locking blocks, and multiple slots are provided on each of the multiple lead screws.

[0013] Furthermore, the bottom ends of the multiple U-shaped plates are respectively fixedly connected to multiple fixed plates, and the top ends of the multiple lead screws are respectively fixedly connected to the main pipe and the connecting pipe, etc., and the bottom ends of the multiple lead screws pass through the multiple U-shaped plates, and the multiple nuts are respectively movably sleeved on the multiple lead screws.

[0014] Furthermore, the multiple card blocks are all fixedly embedded inside the U-shaped plate, and one side of each card block extends into the interior of a multiple card slot.

[0015] As can be seen, in the above technical solution, the two locking blocks and two locking slots work together to limit the lead screw, thereby preventing the lead screw from deflecting when it moves vertically.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. This utility model uses multiple bolts to fix four first connecting plates together, thereby connecting the main pipe, connecting pipe and branch pipe. Branch pipes of different lengths can be flexibly installed according to the width of the inclined tube sedimentation tank and the coverage of the inclined tube array. The airflow is discharged from the air distribution hole in an oblique jet posture, forming a rotating airflow in the gap of the inclined tube in the inclined tube sedimentation tank, thereby achieving efficient flushing, overcoming the "air blockage" phenomenon caused by traditional vertical air distribution, with simple structure, directional air cyclone disturbance, and wide applicability.

[0018] 2. This utility model uses two bolts to install the fixing plate in the inclined tube sedimentation tank. Similarly, another fixing plate is installed. The two fixing plates support the main pipe. By rotating the nut and moving it away from the lead screw, the fixing between the lead screw and the U-shaped plate is released. The main pipe is moved vertically, and the lead screw moves within the U-shaped plate. The height of the main pipe can be adjusted as needed. The structure is simple and easy to use.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] Refer to the instruction manual appendix Figure 1-5This embodiment of a high-efficiency air flushing device for inclined tube sedimentation tank based on directional cyclone disturbance includes a main pipe 1 and a connecting pipe 2, with the connecting pipe 2 located on one side of the main pipe 1. Side pipes 3 are fixedly connected to the opposite sides of the main pipe 1 and the connecting pipe 2. Multiple branch pipes 4 are arranged between the main pipe 1 and the connecting pipe 2. Multiple air distribution holes 10 are opened on the multiple branch pipes 4. First connecting plates 5 are fixedly connected to both ends of the multiple branch pipes 4 and one end of the multiple side pipes 3. The multiple first connecting plates 5 are fixedly connected to each other by bolts. A tapered pipe 7 is fixedly connected to the front end of the main pipe 1, and a second connecting plate 8 is fixedly connected to the front end of the tapered pipe 7.

[0028] Furthermore, gaskets 6 are provided at both ends of the multiple branch pipes 4, and one side of the multiple gaskets 6 is fixedly connected to the first connecting plate 5 on the multiple branch pipes 4 respectively. Multiple air holes 10 are distributed in a double-row symmetrical structure on the side wall of the multiple branch pipes 4, and the opening angle of the air holes 10 is 45 degrees downward from the vertical direction. The diameter of the end of the tapered pipe 7 near the main pipe 1 is smaller than the diameter of the end of the tapered pipe 7 near the second connecting plate 8.

[0029] Furthermore, both the main pipe 1 and the connecting pipe 2 are provided with two support components 9. Each support component 9 includes a fixed plate 901, a U-shaped plate 902, a lead screw 903, two nuts 904, and two locking blocks 906. Each lead screw 903 has multiple locking slots 905. The bottom ends of the U-shaped plates 902 are fixedly connected to the fixed plates 901, and the top ends of the lead screws 903 are fixedly connected to the main pipe 1 and the connecting pipe 2. The bottom ends of the lead screws 903 pass through the U-shaped plates 902. The nuts 904 are movably sleeved on the lead screws 903. The locking blocks 906 are fixedly embedded inside the U-shaped plates 902, and one side of each locking block 906 extends into the interior of the locking slots 905.

[0030] The fixing plate 901 is installed in the inclined tube sedimentation tank by two bolts. Similarly, another fixing plate 901 is installed. The main pipe 1 is supported by the two fixing plates 901. The nut 904 is rotated and moved away from the lead screw 903, thereby releasing the fixation between the lead screw 903 and the U-shaped plate 902. The main pipe 1 is moved vertically, and the lead screw 903 moves within the U-shaped plate 902. The height of the main pipe 1 is adjusted as needed. Similarly, the lead screw 903 is fixed to the U-shaped plate 902 by two nuts 904. The height of the connecting pipe 2 is adjusted in the same way. The structure is simple and easy to use. At the same time, the two locking blocks 906 and the two locking slots 905 cooperate to limit the lead screw 903, thereby preventing the lead screw 903 from deflecting when moving vertically.

[0031] The usage method of this embodiment is as follows:

[0032] In use, the second connecting plate 8 is connected to the air supply pipe by multiple bolts. The airflow generated by the Roots blower enters the main pipe 1 through the conical pipe 7. The conical pipe 7 has a tapered variable diameter structure and the inlet diameter is larger than the outlet diameter, ensuring that the air pressure in each branch pipe 4 is balanced. This effectively avoids the problem of reduced flushing intensity caused by insufficient air volume in the branch pipe 4 at the far end of the pool. The branch pipe 4 is placed between the two side pipes 3 and the four first connecting plates 5 are fixed together by multiple bolts, thereby connecting the main pipe 1, connecting pipe 2 and branch pipe 4. Branch pipes 4 of different lengths can be flexibly installed according to the width of the inclined tube sedimentation tank and the coverage range of the inclined tube array. After the airflow enters the branch pipe 4 through the main pipe 1 and side pipe 3, it is discharged from the air distribution hole 10 in an oblique jet posture, forming a rotating airflow in the gap of the inclined tube in the inclined tube sedimentation tank, thereby achieving efficient flushing and overcoming the "air blockage" phenomenon caused by traditional vertical air distribution. The structure is simple, can directional cyclone disturbance, and has a wide range of applications. At the same time, the gasket 6 can improve the sealing between the branch pipe 4 and the side pipe 3.
