Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to an aeration control device applied to a biochemical filter. Background Art

[0002] Aeration refers to the artificial introduction of air into a biochemical aeration tank through appropriate equipment to achieve the desired effect. Aeration not only oxygenates the liquid within the tank by contacting it with air, but also, by agitating the liquid, accelerates the transfer of oxygen from the air into the liquid, thus completing the oxygenation process. Furthermore, aeration prevents suspended solids from sinking and enhances contact between organic matter, microorganisms, and dissolved oxygen, ensuring sufficient dissolved oxygen for the microorganisms to oxidize and decompose organic matter in the wastewater. The quality of the aeration system not only impacts the effectiveness of biochemical wastewater treatment but also directly affects the treatment site footprint, investment, and operating costs.

[0003] The pipes of existing aeration devices are generally fixedly installed at the bottom of the biochemical filter. When the aeration pipes need to be repaired or maintained, the sewage in the filter needs to be drained, and the staff have to go to the bottom of the filter, which greatly reduces the maintenance efficiency. In addition, aeration can only be started from the bottom, which is inconvenient to adjust the aeration pipes according to different water depths, resulting in uneven aeration and affecting the efficiency of sewage treatment. For this reason, we propose an aeration control device for biochemical filters. Utility Model Content

[0023] During use, the aeration assembly 8 can be adjusted to a suitable position for aeration through the telescopic assembly 9 as needed, thereby improving aeration balance and improving sewage treatment effect. When the aeration assembly 8 needs maintenance, it can also be adjusted to a suitable position through the telescopic assembly 9. Maintenance personnel do not need to empty the sewage in the filter tank wall 1 for maintenance, and do not need to go down to the bottom of the filter tank wall 1, thereby improving maintenance efficiency.

[0024] The telescopic assembly 9 includes several fixed plates 22, which are fixedly installed between the inner and outer walls of the filter tank wall 1. A protective cover 6 is fixedly installed on the fixed plate 22. A first slide bar 13 and a second slide bar 14 are slidably installed on the fixed plate 22 respectively. The lower end of the first slide bar 13 is fixedly connected to a support frame 15, and the support frame 15 and the second slide bar 14 are both fixedly connected. A motor 17 is fixedly installed above the fixed plate 22, and the rotating shaft of the motor 17 is fixedly connected to a driving sprocket 19. The telescopic assembly 9 also includes a movable plate 12, which is mounted above the fixed plate 22. The movable plate 12 is fixedly connected to the first slide bar 13, and the movable plate 12 is fixedly connected to the second slide bar 14. A number of threaded screw rods 16 are provided on the movable plate 12, and a driven sprocket 20 is fixedly sleeved below the threaded screw rods 16. A chain 18 is tensioned between the driven sprocket 20 and the driving sprocket 19. A nut is screwed on the outer surface of the threaded screw rod 16, and the nut on the threaded screw rod 16 is fixedly embedded in the movable plate 12. The bottom of the threaded screw rod 16 is rotatably mounted on the fixed plate 22.

[0025] When the telescopic assembly is working, the transmission shaft of the motor 17 drives the driving sprocket 19 to rotate, and the driving sprocket 19 drives the driven sprocket 20 to rotate through the chain 18, thereby rotating the threaded screw 16, and then the nut of the threaded screw 16 moves up and down, and the nut drives the movable plate 12 to move, thereby driving the entire aeration assembly 8 to start moving.

[0026] The aeration assembly 8 includes several telescopic air tubes 7, which are fixedly connected to a multi-directional outlet pipe 21. The lower ends of the telescopic air tubes 7 are fixedly connected to an aeration pipe 10, on which several single-porous membrane aerators 11 are fixedly mounted. The aeration pipe 10 is fixedly connected to the lower end of the first slide bar 13. During operation, the aeration blower 2 starts, and gas is transferred through the multi-directional outlet pipe 21 to the telescopic air tubes 7, then to the aeration pipe 10, and then enters the single-porous membrane aerators 11, and aeration begins.

[0027] The fixing plate 22 is provided with a plurality of mounting holes for easy installation.

[0028] A plurality of heat sinks are fixedly mounted on the motor 17 , and the heat sinks can greatly improve the heat dissipation of the motor 17 , thereby improving the working efficiency of the motor.

When the movable plate 12 moves up and down, it will pull its corresponding support frame 15, aeration pipe 10 and the single-hole membrane aerator 11 on the support frame 15 up and down. When the support frame 15 moves up and down, the telescopic air pipe 7 will expand and contract to adapt to the adjustment, thereby driving the entire aeration assembly. 8 starts to move, not only can the aeration assembly 8 be adjusted to a suitable height position for repair and maintenance as needed, but maintenance personnel do not need to empty the sewage in the filter tank wall 1 for repair and maintenance, and do not need to go down to the bottom of the filter tank wall 1, thereby improving maintenance efficiency. In addition, the device can adjust the aeration pipe 10 and the single-hole membrane aerator 11 on the support frame 15 to a suitable depth for aeration, which is convenient for adjusting the aeration depth and improving the aeration balance. During aeration, the support frame 15 can also be made to reciprocate up and down to improve the mixing effect of the sewage and improve the sewage treatment effect.

[0030] During aeration, the aeration blower 2 is turned on and starts to work. The gas is transmitted to the telescopic air pipe 7 through the multi-directional air outlet pipe 21 and then to the aeration pipe 10. The gas then enters the single-hole membrane aerator 11 and the aeration operation begins.
