Description

Technical Field

[0001] The invention relates to the technical field of tower-type sewage treatment, and in particular to a tower-type sewage biological treatment device. Background Art

[0002] Tower-type sewage biological treatment equipment is a specific equipment used for sewage treatment. It has a tower-like structure, which is conducive to the formation of a specific water flow state of sewage in the equipment. It is loaded with fillers required for sewage treatment, providing a large amount of attachment surface for microorganisms, which helps to fix the structure of the microbial community.

[0003] When the existing tower treatment equipment is used for biological treatment of sewage, as the microorganisms continue to multiply and accumulate, they will clog the pores of the filler, reducing the subsequent treatment efficiency. Therefore, the filler needs to be replaced and cleaned regularly. When replacing the filler inside the tower treatment equipment, the steps are relatively cumbersome, and the long-term accumulation and attachment of microorganisms will affect the efficiency of subsequent cleaning, causing the filler to be damaged during the cleaning process.

[0004] In addition, the filler needs to be compacted after loading to ensure the gaps between the fillers to ensure the efficiency of sewage treatment. Therefore, conventional clean water flushing mainly acts on the surface filler, and has little effect on the cleaning of the filler inside, resulting in low short-term cleaning efficiency of the filler.

Example

[0036] Reference Figure 1-3 and Figure 11-13The difference between this embodiment and embodiment 1 is that an exhaust pipe 3001 is connected to the top of the outer tower body 300, a water collecting ring 3003 is provided at the bottom of the inner cavity of the lower filter cartridge 3, and a drainage pipe 3002 is connected to the outer side of the lower filter cartridge 3 for discharging the liquid inside the water collecting ring 3003.

The inner surface of the intercepting ring 141 is movably mounted on the outer surface of the water filter plate 31. When the top pad 402 and the bottom pad 403 are adjusted in position and height, the water flow control disk 14 can also be adjusted synchronously, and the water flow control disk 14 can synchronously drive the intercepting ring 141 to adjust the position and height.

[0038] Specifically, refer to Figure 11-13 A balancing ring sleeve 3004 is provided at the bottom of the inner side of the water collecting ring 3003, and a water hole 3005 is provided on the balancing ring sleeve 3004. A guide hole 3006 is provided on the top surface of the water collecting ring 3003 for the water flow control disk 14 to drive the intercepting ring 141 to adjust the height. In the sewage treatment stage, when the top pad 402 and the bottom pad 403 cooperate with the upper filter cartridge 2 and the lower filter cartridge 3 to compact the internal filler, the water flow control disk 14 is at the bottom of the reciprocating wire groove C103. At this time, the top surface of the water flow control disk 14 is flush with the bottom surface of the water hole 3005, and the bottom surface of the synchronous intercepting ring 141 is in contact with the top surface of the exhaust pipe 3001, so that the water flow falling through the water filter plate 31 can fall on the water flow control disk 14. The top surface, according to the inclined setting of the top surface of the water flow control disk 14, allows water to flow into the water collecting trough 200 for collection. In the stage of flushing and cleaning the filler, the top pad 402 and the bottom pad 403 cooperate with the upper filter cartridge 2 and the lower filter cartridge 3 respectively to relax the internal filler, and the water flow control disk 14 is at the top of the reciprocating wire groove C103. The top surface of the water flow control disk 14 is flush with the top surface of the water collecting ring 3003, and the bottom surface of the intercepting ring 141 is also synchronously separated from the top surface of the water collecting ring 3003. At this time, the water falling on the top surface of the water flow control disk 14 will flow into the top surface of the water collecting ring 3003, and then be discharged and collected through the drain pipe 3002, so that in the two treatment stages, the flow path of the water flow at the bottom of the outer tower body 300 will be adjusted synchronously.

[0039] For other structures not described, refer to Example 1.

[0040] Working principle: In the present invention, when biological treatment of sewage is carried out, the sewage to be treated is introduced into the water distributor 7 through the external sewage pipe through the water inlet pipe 71, and the sewage is evenly distributed to the filler in the upper filter cartridge 2 through the water distributor 7; After the sewage is processed by the filler inside the upper filter cartridge 2, the sewage will enter the lower filter cartridge 3 through the top pad 402, the telescopic connecting tube 401 and the bottom pad 403 in sequence, and the material will be processed for the second time by the filler inside the lower filter cartridge 3; The water flow treated by the filler inside the lower filter cartridge 3 will fall to the top surface of the water flow control disk 14 by gravity. Through the inclined setting of the top surface of the water flow control disk 14, the treated water will fall into the water collection tank 200 to complete the collection operation; When the internal fillers of the upper filter cartridge 2 and the lower filter cartridge 3 have a certain impact on the sewage biological treatment efficiency, the output shaft of the drive motor 400 is turned on for forward rotation. At this time, the transmission effect of the linkage mechanism 9, the transmission mechanism A12 and the transmission mechanism B13 is utilized to allow the adjustment shaft 1 to rotate. At this time, the top pad 402 and the bottom pad 403 move away from each other, the top pad 402 moves downward, and the bottom pad 403 moves upward, so that the space for loading fillers inside the upper filter cartridge 2 and the lower filter cartridge 3 is increased, and the water flow control disk 14 moves upward. When the increase in the internal space of the upper filter cartridge 2 and the lower filter cartridge 3 by the top pad 402 and the bottom pad 403 reaches the maximum value, the top surface of the water flow control disk 14 will be flush with the top surface of the water collecting ring 3003; After the above structure adjustment is completed, the reverse mode of the output shaft of the driving motor 400 is turned on, and the linkage between the linkage mechanism 9 and the stirring mechanism 11 is used to allow the stirring frame 1108 to stir the fillers inside the upper filter cartridge 2 and the lower filter cartridge 3, so that the fillers can perform position adjustment movement inside the upper filter cartridge 2 and the lower filter cartridge 3; When the output shaft of the driving motor 400 starts to reverse, the water spray panel 22 is opened synchronously, and a high-pressure water flow is supplied to the water spray panel 22 through an external water supply pipe. During the stirring process of the filler, the water flow cleans and rinses the filler; The water flow after flushing the filler will fall on the top surface of the water flow control plate 14, then flow into the water collecting ring 3003, and then be discharged and collected through the drain pipe 3002. At this time, the water flow will not fall into the water collecting tank 200 through the top surface of the water flow control plate 14; After the filler is flushed, the output shaft of the drive motor 400 is turned forward, so that the top pad 402 and the bottom pad 403 cooperate with the upper filter cartridge 2 and the lower filter cartridge 3 to compact the filler inside the two again, so as to quickly put them into the subsequent sewage biological treatment process.

The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
