Description
Technical Field
[0001] This utility model relates to the field of biological packing support technology for sewage treatment, and in particular to a detachable biological packing support for sewage treatment. Background Technology
[0002] In the field of wastewater treatment, biological packing support is a core component that supports biological packing, ensures microbial attachment, and enhances wastewater purification efficiency. Existing biological packing supports are mostly fixed, integrated structures with significant drawbacks: First, they are large, non-separable, and difficult to transport and install on-site, and cannot flexibly adjust the number of support units according to the actual size of the wastewater treatment tank, resulting in poor adaptability. Second, assembly requires specialized tools, is cumbersome, time-consuming, and labor-intensive. Third, the fixed vertical spacing of the support makes it difficult to adapt to biological packing of different heights, easily leading to low packing utilization and affecting purification efficiency. Furthermore, the lifting lugs are mostly made of ordinary materials, which are prone to wear and tear over long-term use, shortening the overall lifespan of the support and causing numerous inconveniences in actual wastewater treatment operations. To address the shortcomings of existing technologies, we propose a detachable wastewater treatment biological packing support. Utility Model Content
[0003] The main purpose of this utility model is to provide a detachable biological packing support for sewage treatment, which can effectively solve the problems in the background art.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A detachable biological packing support for sewage treatment includes an upper connecting plate and a lower connecting plate. Two fixing cylinders are symmetrically fixed to the lower end of the upper connecting plate, and two fixing rods are symmetrically fixed to the upper end of the lower connecting plate. Multiple lifting lugs are fixedly connected to the lower end of both the upper and lower connecting plates. Connecting rods are fixedly connected to the upper ends of the fixing rods, and multiple limiting grooves are formed on the inner walls of the fixing cylinders. Limiting blocks are fixedly connected to the outer surfaces of the connecting rods at corresponding limiting grooves. Two first rotating handles are symmetrically arranged above the upper connecting plate. First rotating rods are fixedly connected to the lower ends of the first rotating handles, and fixing rings are fixedly connected to the outer surfaces of the first rotating rods. Two sets of balls are rolled between the outer surface of the fixed ring and the inner cavity of the upper connecting plate. A first threaded rod is fixedly connected to the lower end of the first rotating rod. A second rotating handle is provided above the upper connecting plate. A second rotating rod is fixedly connected to the lower end of the second rotating handle. A first bevel gear is fixedly connected to the lower end of the second rotating rod. A second bevel gear is meshed with both sides of the first bevel gear. A second threaded rod is fixedly connected to one side of the second bevel gear. A moving block is threadedly connected to the outer surface of the second threaded rod. A fixed plate is fixedly connected to one end of the moving block. A plug rod is fixedly connected to one side of the fixed plate. Two connecting blocks are symmetrically fixed to the rear end of the upper connecting plate.
[0005] Preferably, the outer diameter of the connecting rod is adapted to the inner diameter of the fixed cylinder, and the length of the connecting rod is less than the depth of the fixed cylinder. The limiting block and the limiting groove are in sliding fit, and the length direction of the limiting groove is consistent with the axial direction of the fixed cylinder.
[0006] Preferably, the two sets of balls are evenly spaced along the circumference of the fixed ring, and the number of balls in each set is set according to the size of the fixed ring to ensure stable rolling. The inner cavity of the upper connecting plate and the outer surface of the fixed ring are both provided with annular mounting grooves. The balls roll in the two annular mounting grooves, and the width of the annular mounting groove is adapted to the diameter of the balls. The connecting rod is threaded to the outer surface of the first threaded rod.
[0007] Preferably, the end of the plug rod away from the fixed plate has a chamfer to facilitate plugging, and an O-ring plug hole is opened on one side surface of the connecting block, and the plug rod matches the O-ring plug hole opened on the surface of the connecting block.
[0008] Preferably, the lifting lugs at the lower end of the upper connecting plate and the lifting lugs at the upper end of the lower connecting plate are symmetrically distributed vertically, and the lifting lugs are all located near the edges of the upper and lower connecting plates. The lifting lugs are provided with circular lifting holes, and a wear-resistant bushing is fixedly embedded in the inner wall of the lifting hole. The wear-resistant bushing is made of corrosion-resistant metal material, and the inner wall of the wear-resistant bushing is flush with the inner wall of the lifting hole.
[0009] Compared with the prior art, the present invention has the following beneficial effects: This detachable biological packing support for wastewater treatment utilizes a combination of a fixed cylinder and a fixed rod, along with the threaded connection between the first threaded rod and the connecting rod, and the guiding effect of the limiting block and the limiting groove. The transmission design of the first and second bevel gears drives the insertion of the connecting rod and the connecting block, enabling efficient assembly and disassembly of the support. Without the need for complex tools, the initial splicing of the upper and lower connecting plates and the lateral connection of multiple support units can be quickly completed. The number of support units can be flexibly adjusted according to the actual scale of the wastewater treatment tank, significantly shortening installation time and reducing labor costs. It effectively solves the problems of cumbersome assembly and poor adaptability of traditional biological packing supports, significantly improving the convenience and flexibility of installation operations.
[0010] This detachable biological wastewater treatment packing support uses a first rotating handle to drive the first threaded rod to rotate, which, in conjunction with a limiting block, restricts the synchronous rotation of the connecting rod. This allows for precise adjustment of the distance between the upper and lower connecting plates, perfectly adapting to biological wastewater treatment packings of different heights and ensuring that the packing fully exerts its purification function and improves wastewater treatment efficiency. Meanwhile, the corrosion-resistant and wear-resistant metal bushings embedded in the lifting lugs effectively reduce wear during hoisting and long-term use, extending the service life of the lifting lugs and the support as a whole. Furthermore, the compact size of each component after disassembly facilitates transportation and storage, reducing subsequent maintenance and handling costs, and solving the problems of fixed spacing, insufficient durability, and inconvenient transportation associated with traditional supports.

[0013] 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.
[0014] Example 1, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a detachable biological packing support for sewage treatment includes an upper connecting plate 1 and a lower connecting plate 2. Two hollow fixing cylinders 3 are symmetrically welded and fixed to the lower end of the upper connecting plate 1. Two fixing rods 4 are symmetrically welded and fixed to the upper end of the lower connecting plate 2, corresponding to the positions of the fixing cylinders 3. A connecting rod 6 is integrally formed at the upper end of each fixing rod 4. The connecting rod 6 has an internal thread along the axial direction. Two first rotating handles 9 are symmetrically arranged above the upper connecting plate 1. A first rotating rod 10 is welded and fixed to the lower end of each first rotating handle 9. A fixing ring 11 is welded and fixed to the outer surface of the first rotating rod 10. The inner cavity of the upper connecting plate 1 and the fixing ring... The outer surface of the fixed ring 11 is provided with annular mounting grooves. The width of the annular mounting grooves is adapted to the diameter of the ball bearings 12. Two sets of ball bearings 12 are evenly spaced along the circumference of the fixed ring 11 and are rolled in the annular mounting grooves. The lower end of the first rotating rod 10 passes through the upper connecting plate 1 and extends into the fixed cylinder 3. The extended end is welded to and fixed with a first threaded rod 13. The external thread of the first threaded rod 13 is adapted to the internal thread of the connecting rod 6 to form a threaded connection. The inner wall of the fixed cylinder 3 is provided with multiple limiting grooves 7 along its axial direction. The outer surface of the connecting rod 6 is integrally formed with a sliding groove 7 corresponding to the position of the limiting groove 7. The limiting block 8, through its sliding fit with the limiting groove 7, restricts the connecting rod 6 from rotating synchronously with the first threaded rod 13. Multiple symmetrically distributed lifting lugs 5 are welded and fixed to the edges of both the upper connecting plate 1 and the lower connecting plate 2. Circular lifting holes are provided on the lifting lugs 5, and a wear-resistant bushing made of corrosion-resistant metal is embedded and fixed to the inner wall of the lifting hole. The inner wall of the wear-resistant bushing is flush with the inner wall of the lifting hole. A second rotating handle 14 is provided on one side of the upper connecting plate 1. A second rotating rod 15 is welded and fixed to the lower end of the second rotating handle 14, and a first bevel gear 16 is welded and fixed to the lower end of the second rotating rod 15. The first bevel gear 16 is meshed with the second bevel gear 17 on both sides. The second bevel gear 17 is welded to one side and fixed with the second threaded rod 18. The outer surface of the second threaded rod 18 is threaded with the moving block 19. The moving block 19 is welded to one end and fixed with the fixing plate 20. The fixing plate 20 is welded to one side and fixed with the plug rod 21. The end of the plug rod 21 away from the fixing plate 20 is provided with a chamfer to facilitate plugging. The corresponding side surface of the other upper connecting plate 1 that is connected to the upper connecting plate 1 is welded to two connecting blocks 22. One side surface of the connecting block 22 is provided with an O-type plug hole that matches the plug rod 21.
[0015] It should be noted that this utility model is a detachable biological packing support for sewage treatment. In use, first align the connecting rod 6 at the top of the fixing rod 4 on the lower connecting plate 2 with the fixing cylinder 3 at the lower end of the upper connecting plate 1, so that the limiting block 8 on the outer surface of the connecting rod 6 is aligned with the limiting groove 7 on the inner wall of the fixing cylinder 3. Simultaneously, align the first threaded rod 13 with the internal threaded hole of the connecting rod 6. Rotate the first handle 9 to drive the first rotating rod 10 and the first threaded rod 13 to rotate. Utilizing the threaded engagement between the first threaded rod 13 and the connecting rod 6, the connecting rod 6 is screwed into the fixing cylinder 3, completing the initial splicing of a single upper connecting plate 1 and lower connecting plate 2. When it is necessary to connect two upper connecting plates... When the connecting plates 1 are fixed together, align the mating sides of the two upper connecting plates 1, and rotate the second rotating handle 14 on one of the upper connecting plates 1. The second rotating handle 14 drives the second rotating rod 15 and the first bevel gear 16 at the lower end to rotate. The first bevel gear 16 drives the second bevel gear 17 and the second threaded rod 18 to rotate through meshing with the second bevel gears 17 on both sides. When the second threaded rod 18 rotates, it drives the moving block 19 with the threaded connection on the outer surface to move horizontally. The moving block 19 drives the fixed plate 20 and the insertion rod 21 to move synchronously until the insertion rod 21 is inserted into the O-shaped insertion hole of the connecting block 22 on the other upper connecting plate 1, realizing the connection of the two upper connecting plates. After the horizontal fixing of the connecting plate 1, according to the installation height requirements of the sewage treatment biological packing, the first rotating handle 9 is rotated in the forward or reverse direction. The first rotating handle 9 drives the first rotating rod 10 and the first threaded rod 13 to rotate. Since the limiting block 8 and the limiting groove 7 restrict the rotation of the connecting rod 6, the connecting rod 6 will move up and down along the axis of the fixed cylinder 3, thereby adjusting the distance between the upper connecting plate 1 and the lower connecting plate 2. During the adjustment process, the fixing ring 11 achieves stable rolling through the ball bearings 12 between it and the inner cavity of the upper connecting plate 1, ensuring the smoothness of the adjustment operation. Finally, the sewage treatment biological packing is suspended and installed through the lifting holes on the lifting lug 5. The wear-resistant bushing inside the mounting hole can reduce the wear on the lifting lug 5 during hoisting, extend the service life of the lifting lug 5, and complete the assembly of the entire support and the installation of the biological packing. When it is necessary to disassemble the support, first rotate the second handle 14 in the opposite direction to make the insertion rod 21 exit from the O-shaped insertion hole of the connecting block 22 on the other upper connecting plate 1, separating the two upper connecting plates 1. Then rotate the first handle 9 in the opposite direction to make the first threaded rod 13 disengage from the connecting rod 6. Pull the lower connecting plate 2 down to make the connecting rod 6 withdraw from the fixed cylinder 3, thus realizing the separation of the upper connecting plate 1 and the lower connecting plate 2, which facilitates the transportation, storage and subsequent maintenance of the support.
