Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment aeration equipment, in particular to a liftable aeration device for an aeration tank. Background Art

[0002] Aeration refers to the process of forcibly transferring oxygen in the air to the liquid, with the purpose of obtaining sufficient dissolved oxygen. In addition, aeration also prevents the suspended matter in the pool from sinking and strengthens the contact between the organic matter in the pool and the microorganisms and dissolved oxygen, thereby ensuring that the microorganisms in the pool can oxidize and decompose the organic matter in the sewage under the condition of sufficient dissolved oxygen. The suction port of the aeration pump, the core component of the aeration system, can use negative pressure to inhale gas, so there is no need to use an air compressor and an atmospheric ejector.

[0003] The aeration system has a simple structure. During the flotation process, the flotation route and depth cannot be controlled, making it difficult to aerate the sewage in the pool. Artificial feed is usually added at one time, and it is difficult to scientifically control the reaction between organic matter and microorganisms in the sewage. Therefore, the aeration system and the feed system are optimized and improved. Utility Model Content

[0004] The purpose of the utility model is to provide a liftable aeration device to solve the problems raised in the above background technology.

[0021] Please refer to Figure 1 and 2, in the embodiment of the present utility model, a liftable aeration device includes an aeration tank 1, an aeration pump 3, an aeration member 4, and an aeration pipeline 18. The aeration pump 3 is installed with the aeration member 4 located in the aeration tank 1 through the aeration pipeline 18. Both sides of the aeration member 4 are installed in the aeration tank 1 through a limiting member. A winch 9 capable of lifting and lowering the aeration member 4 is provided at the top of the aeration tank 1;

[0022] The limiting member includes a locking ring 11, a vertical pipe 5, and a connecting member 6. The vertical pipe 5 is installed on the inner wall of the aeration tank 1 through the connecting member 6. The aeration member 4 is installed outside the vertical pipe 5 through the locking ring 11. The locking ring 11 is in a C-shaped form with an opening. The aeration pump 3 transports gas to the aeration pipeline 18 through a main pipeline 2. The weight of the aeration member 4 is greater than that of the sewage. Therefore, the aeration member 4 sinks downward into the aeration tank 1. Under the dragging of the winch 9, the aeration member 4 is maintained at a certain height. As the main fixing member of the aeration member 4, the limiting member can prevent the aeration member 4 from shaking and tilting during aeration and sewage agitation while satisfying the condition of the up-and-down movement of the aeration member 4. The opening of the locking ring 11 can pass through the connecting member 6. After the aeration member 4 has been rising all the time, it can break away from the vertical pipe 5 and move to the ground, enabling modular management of the aeration device. When performing maintenance and cleaning, there is no need for workers to tie safety ropes to work on the pipelines above the pool, improving the safety during maintenance operations, and being able to adjust the aeration height, which can promote the biodegradation process of organic matter in sewage, improve the degradation efficiency of organic matter in sewage, and reduce energy consumption and operating costs.

[0023] In a preferred embodiment, the aeration member 4 and the aeration pipeline 18 are connected through a hose 12. Gas can be sent to the aeration member 4 through the aeration pipeline 18 and the hose 12 and distributed from the aeration disc. The lifting and lowering of the aeration member 4 requires a flexible connection of the gas supply pipeline between the aeration member 4 and the aeration pipeline 18. Therefore, a hose 12 or a flexible hose is provided to meet the height change during the moving and lifting process.

[0024] In a preferred embodiment, the winch 9 is installed on the ground through a rotating bracket 8 and a sleeve base 7. The rotating bracket 8 is rotatably installed in the sleeve base 7. The winch 9 is installed on the rotating bracket 8. The winch 9 is fixed to the aeration member 4 through a traction rope 10. After the winch 9 lifts the aeration member 4 out of the aeration tank 1, the rotation of the rotating bracket 8 in the sleeve base 7 can move the aeration member 4 to the ground. The hose 12 and the rotating bracket 8 can be arranged on the same side to reduce the length of the hose 12.

[0025] In a preferred embodiment, the winch 9 is directly above the center of the aeration member 4. The winch 9 pulls the aeration member 4 upward and maintains the balance of the aeration member 4. The number of the traction ropes 10 can be multiple.

[0026] In a preferred embodiment, it further includes an air-assisted feeding system;

[0027] The air-assisted feeding system includes a mixing tank 17, a valve 15, a Venturi tube 14, and an air delivery tube 13. The gas inlet of the Venturi tube 14 is connected to the output end of the aeration pump 3. The feeding port of the Venturi tube 14 is connected to the discharge end of the mixing tank 17 through the valve 15. The gas outlet of the Venturi tube 14 is connected to the air delivery tube 13 that extends into the aeration tank 1. By turning on the aeration pump 3 for aeration, the air-assisted feeding system is activated. The main pipeline 2 is connected to the air delivery tube 13 and the aeration pipeline 18 respectively through a three-way valve 16. By switching the three-way valve 16, the conveying route of the air flow is controlled. The air flow is blown into the aeration tank 1 through the Venturi tube 14 for oxygenation. At the same time, when the air flow passes through the Venturi tube 14, the feeding material in the mixing tank 17 is sucked out, discharged with the air delivery tube 13 for oxygenation, and injected into the aeration tank 1.

[0028] In a preferred embodiment, the valve 15 is a flow control valve that controls the output speed of the liquid phase. If the material in the mixing tank 17 is liquid, the flow control valve is used to control the outflow of the liquid phase and add it to the aeration tank 1.

[0029] In a preferred embodiment, the valve 15 is a rotary valve that controls the output speed of the granular material. If the material in the mixing tank 17 is granular, the rotary valve is used to control the output of the granular material and add it to the aeration tank 1. It is simple and convenient to control, has a low transformation cost, can achieve automated program control, and is more accurate than manual feeding.

[0030] It should be noted that the above embodiments all belong to the same inventive concept of the utility model. The descriptions of the embodiments have their own focuses. For the parts not described in detail in individual embodiments, reference can be made to the descriptions in other embodiments.

[0031] The above embodiments only represent the implementation modes of the utility model. The descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be pointed out that for those of ordinary skill in the art, without departing from the inventive concept of the utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
