Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a high-efficiency biological aeration tank for wastewater treatment. Background Technology

[0002] The aeration tank uses the activated sludge process for wastewater treatment. The tank provides a certain retention time for the wastewater to meet the oxygen requirements of aerobic microorganisms and the mixing conditions for sufficient contact between wastewater and activated sludge.

[0003] Patent CN220618638U discloses an aeration tank for wastewater treatment, comprising a tank body. A motor, a variable frequency motor, is fixedly connected to the outer surface of the right end of the tank body. A coupling is fixedly connected to the left end of the motor's output shaft, and a reciprocating lead screw is fixedly connected to the left end of the coupling. A sleeve is fixedly connected to the outer surface of the left end of the tank body. The reciprocating lead screw extends through to the outside of the tank body and is rotatably connected to it. A sliding plate is helically connected to the outer surface of the reciprocating lead screw, and a pull rod is fixedly connected to the outer surface of the sliding plate. By setting up components such as a piston plate, sleeve, and reciprocating lead screw, the oxygen supply in the tank can be adjusted by regulating the movement speed of the piston plate. This helps to maintain the dissolved oxygen content in the tank within an appropriate range, thereby ensuring the normal development and reproduction of microorganisms in the water and effectively improving the quality of wastewater purification treatment.

[0004] The aeration tank mentioned in the above patent has its air intake volume adjusted by the speed of the reciprocating screw driven by the motor, but it cannot adjust the air intake volume according to the amount of sewage in the aeration tank. Users also need to adjust the speed of the motor according to the amount of sewage to be treated, which is inconvenient to use. Therefore, we need to propose a high-efficiency biological aeration tank for sewage treatment. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention utilizes an air inlet pipe and an aeration assembly to introduce air into the wastewater inside the tank for aeration. During aeration, the use of a stirring assembly further enhances the wastewater treatment effect. Furthermore, the device incorporates a connecting pipe and an adjusting assembly, forming a U-shaped connector structure with the tank. As the volume of wastewater inside the tank increases, the water level rises, causing the buoyancy block to push the adjusting plate upwards via a connecting rod, thus expanding the air intake channel of the air inlet pipe and increasing the air intake volume. This device allows for adjustment of the aeration volume based on the amount of wastewater inside the tank, thereby improving the wastewater treatment effect. Attached Figure Description

Detailed Implementation

[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 Figures 1-6 This utility model provides a high-efficiency biological aeration tank for sewage treatment, including a tank body 1, with an inlet pipe 19 connected to the top of one side of the tank body 1 and a drain pipe 20 connected to the bottom of one side of the tank body 1. It also includes an air inlet pipe 2 connected to the top of one side of the tank body 1, with an aeration assembly connected to one end of the air inlet pipe 2 located in the inner cavity of the tank body 1. The aeration assembly includes a connecting pipe 10 connected to one end of the air inlet pipe 2; a branch pipe 11 connected to the bottom end of the connecting pipe 10; an aeration pipe 12 connected to both ends of one side of the branch pipe 11; and several sets of nozzles 13 fixedly installed on the top of the aeration pipe 12.

[0025] In this embodiment, wastewater is discharged into the tank 1 through the inlet pipe 19, and the treated wastewater is discharged to the outside through the outlet pipe 20. With the aeration assembly, the user can connect an air pump to one end of the air inlet pipe 2. The air pump draws external air into the air inlet pipe 2, and the air is then introduced into the nozzle 13 through the connecting pipe 10, branch pipe 11, and aeration pipe 12. The nozzle 13 then discharges air into the wastewater to aerate it.

[0026] The connecting pipe 10, branch pipe 11, and aeration pipe 12 are all fixedly mounted with positioning seats 14, one side of which is fixedly connected to the inner wall of the tank body 1. The positioning seats 14 improve the stability of the installation of the connecting pipe 10, branch pipe 11, and aeration pipe 12, and fix them to the inner wall of the tank body 1.

[0027] Preferably, the inner cavity of the tank body 1 is equipped with a stirring assembly for stirring the sewage; the stirring assembly includes a drive motor 15 fixedly installed on one side of the tank body 1, the output shaft of the drive motor 15 passing through the tank body 1 and extending into the inner cavity of the tank body 1; a rotating rod 16 fixedly installed on the output shaft of the drive motor 15, the end of the rotating rod 16 away from the drive motor 15 being rotatably connected to the inner wall of the tank body 1; and a stirring rod 17 fixedly installed on the surface of the rotating rod 16.

[0028] By setting up the stirring component, the sewage can be stirred during the aeration process to improve the sewage treatment effect. Specifically, the output shaft of the drive motor 15 drives the rotating rod 16 to rotate, which in turn drives the stirring rod 17 to rotate and stir the sewage.

[0029] In addition, a rotating seat 18 is fixedly installed on one side of the inner cavity of the pool body 1, corresponding to the rotating rod 16. One end of the rotating rod 16 is rotatably connected to the inner wall of the rotating seat 18. The rotating seat 18 provides auxiliary support for one end of the rotating rod 16. The rotatable connection between one end of the rotating rod 16 and the inner wall of the pool body 1 via the rotating seat 18 improves the stability of the rotation of the rotating rod 16.

[0030] It is worth noting that this device also includes a connecting pipe 3 connected to the bottom of one side of the pool body 1. The connecting pipe 3 is L-shaped, and the end of the connecting pipe 3 away from the pool body 1 is connected to the bottom of the air inlet pipe 2. It also includes an adjustment component located between the air inlet pipe 2 and the connecting pipe 3 for adjusting the air intake volume according to the amount of sewage inside the pool body 1. The adjustment component includes a fixed shell 4 connected to the top of the air inlet pipe 2. An adjustment plate 5 is slidably installed in the inner cavity of the fixed shell 4. The bottom of the adjustment plate 5 passes through the fixed shell 4 and the air inlet pipe 2 in sequence and extends into the inner cavity of the air inlet pipe 2. A buoyancy block 6 is slidably located in the inner cavity of the connecting pipe 3. A connecting rod 7 is fixedly connected to the top of the buoyancy block 6. The top of the connecting rod 7 is fixedly connected to the bottom of the adjustment plate 5.

[0031] The connecting pipe 3 and the tank body 1 form a U-shaped communicating vessel structure. As the amount of sewage inside the tank body 1 increases, the water level rises, causing the buoyancy block 6 to push the adjusting plate 5 upwards via the connecting rod 7, thus expanding the air intake channel of the air intake pipe 2 and increasing the air intake volume. When the water level drops, the adjusting plate 5 moves downwards under the weight of the adjusting plate 5, connecting rod 7, and buoyancy block 6, returning to its initial position. This device allows for adjustment of the aeration air intake volume according to the amount of sewage inside the tank body 1, improving the sewage treatment effect. It should be noted that sewage may contaminate the buoyancy block 6, causing its surface to become stuck against the inner wall of the connecting pipe 3. Users can periodically disassemble the buoyancy block 6 for cleaning to ensure its operational stability. This embodiment does not describe how to disassemble the buoyancy block 6; those skilled in the art can install this structure by rotating the detachable mounting structure according to the actual assembly situation.

[0032] Furthermore, the device also includes a support assembly for improving the stability of the connecting rod 7's movement. The support assembly includes a support plate 8 fixedly installed within the inner cavity of the connecting pipe 3, positioned above the buoyancy block 6; and a through hole 9 formed on the surface of the support plate 8, with the surface of the connecting rod 7 slidably connected to the inner wall of the through hole 9. By providing the support assembly, the stability of the movement of the adjusting plate 5 and the connecting rod 7 can be improved, as the surface of the connecting rod 7 slides within the inner cavity of the through hole 9 during movement. Additionally, to improve the airtightness between the connecting rod 7 and the through hole 9, a sealing ring can be installed between them to enhance airtightness and prevent air from the air inlet pipe 2 from flowing back into the pool body 1 through the connecting pipe 3.

[0033] The high-efficiency biological aeration tank for wastewater treatment in this embodiment, compared with traditional aeration tanks for wastewater treatment, can adjust the aeration rate according to the wastewater volume, eliminating the need for staff to constantly adjust the aeration rate based on the wastewater volume, thus effectively improving wastewater treatment efficiency.

[0034] 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.
