During use, the nylon ropes are prone to tangling, which not only affects the biofilm formation but also causes the packing material to clog the equipment. In addition, when performing maintenance such as corrosion or sealing inside the tank, the entire hanging rack needs to be removed, which is laborious. Therefore, this utility model proposes a buried sewage biological bacteria growth substrate hanging rack that can solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4

[0025] A buried sewage biological bacteria growth substrate rack is provided:

[0026] The housing 10 has an inlet pipe 12 and a drain pipe 13, which are used to transport sewage and discharge treated sewage, respectively. Valve bodies are installed on the inlet pipe 12 and the drain pipe 13.

[0027] The outer wall of the housing 10 is connected to a support plate 11, and an annular groove 111 is provided on the support plate 11. The support frame 20 is located on the top of the housing 10. The support frame 20 is connected to a ball bearing 21 that rolls and engages with the annular groove 111. A motor body 30 is installed on the housing 10. The motor body 30 can drive the support frame 20 to rotate through the transmission part 31.

[0028] The transmission unit 31 includes a gear 311 connected to the output end of the motor body 30 and an arc-shaped tooth segment 312 connected to the support frame 20. The gear 311 meshes with the arc-shaped tooth segment 312. Through the operation of the motor body 30, the meshing of the gear 311 and the arc-shaped tooth segment 312 can drive the support frame 20 to rotate on the top of the housing 10.

[0029] The support frame 20 is connected to the two sides of the support plate 40 respectively. Each support plate 40 has multiple sets of liner plates 41 distributed on it. The multiple sets of liner plates 41 are slidably connected to the support plate 40. Each set of liner plates 41 is provided with multiple sets of hanging rods 42. Each set of hanging rods 42 is connected to the top of the end ...

[0030] The hanging rod 42 can be made of rigid plastic or the like. The filling part 44 serves as a habitat for microorganisms that cultivate the biofilm, providing a carrier for biofilm formation. The multiple recessed sections 442 on the wall of the ring body 441 can increase the surface area and provide support for the attachment of microorganisms, thus avoiding entanglement and ensuring good biofilm quality.

[0031] An air pump is installed outside the tank 10. The air supply pipe of the air pump is connected to an aeration pipe, which is located on the bottom wall of the tank 10. The air pump and the aeration pipe are not shown. The bottom of the hanging rod 42 is vertically spaced from the aeration pipe. When the air pump is working, it delivers air into the sewage through the aeration pipe to provide sufficient oxygen for the nitrifying bacteria. It also enhances the contact between organic matter, ammonia nitrogen and biofilm in the sewage through bubble agitation, thereby improving the sewage treatment effect.

[0032] Each set of pallets 40 is equipped with a telescopic cylinder 45, and the movable rod of the telescopic cylinder 45 is connected to the outermost pallet 40. The innermost liner 41 on each set of pallets 40 is fixedly connected to the pallet 40. The telescopic part 43 includes multiple springs, which are stainless steel springs.

[0033] When maintaining the housing 10, after the sewage inside the housing 10 is discharged, the telescopic cylinder 45 drives the outermost support plate 40 to move inward and pushes multiple support plates 40 to move, thereby reducing the space occupied by the hanging rods 42 inside the housing 10 and exposing the space at both ends of the housing 10 for maintenance. After maintenance is completed in one direction of the housing 10, the motor body 30 drives the support frame 20 to rotate, thereby exposing the two ends of the housing 10 in the other direction, realizing comprehensive maintenance of the housing 10 without having to remove multiple sets of hanging rods 42, making maintenance convenient.

[0034] Each set of liner plates 41 is provided with a stop block 411, which can abut against the adjacent set of liner plates 41 to limit the minimum gap between the two sets of liner plates 41. By limiting the minimum gap, the fillers on the hanging rod 42 will not collide with each other.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
