Description

Technical Field

[0001] The present invention belongs to the field of aeration devices in sewage treatment, and particularly relates to a rotatable tubular aerator. Background Art

[0002] In sewage treatment, aeration refers to introducing air into the biochemical aeration tank through appropriate equipment to achieve the expected purpose. Aeration not only makes the liquid in the tank contact with air for oxygenation, but also accelerates the transfer of oxygen in the air to the liquid due to the agitation of the liquid, thus completing the purpose of oxygenation; in addition, aeration also has the purpose of preventing the suspension in the tank from sinking and strengthening the contact between the organic matter, microorganisms and dissolved oxygen in the tank, so as to ensure that the microorganisms in the tank oxidize and decompose the organic matter in the sewage under the condition of sufficient dissolved oxygen. The quality of the aeration device not only affects the sewage biochemical treatment effect, but also directly affects the land occupation, investment and operation cost of the treatment plant. The blower aeration device mainly consists of an aeration blower, a connecting pipe and an aerator.

[0003] Currently, the aerator is usually installed at the bottom of the tank. During aeration, the gas moves upward and is fully mixed with the sewage to complete the oxygenation process of the entire water body. However, the aeration volume distribution of the traditional aerator is uneven, and sedimentation of bottom sludge is likely to occur at the bottom of the tank. Based on this, the applicant purposefully provides a rotatable tubular aerator, which can accelerate the mixing of gas and sewage, improve the aeration efficiency, and the rotating aeration pipe can stir the sewage at the bottom of the tank to avoid the problem of bottom sludge sedimentation. Summary of the Invention

[0004] The purpose of the present invention is to solve the above problems. The present application proposes a rotatable tubular aerator, which can accelerate the mixing of gas and sewage, improve the aeration efficiency, and the rotating aeration pipe can stir the sewage at the bottom of the tank to avoid the problem of bottom sludge sedimentation.

[0005] To achieve the above purpose, the present invention provides the following technical solutions: A rotatable tubular aerator includes an aeration pipe part, a tubular aerator part, and a rotating part. The aeration pipe part includes an aeration branch pipe. The aeration branch pipe extends along the pool wall into the bottom of the pool, with one end inside the pool body and the other end outside the pool body. A regulating valve is provided on the aeration branch pipe located outside the pool body, and the aeration branch pipe located inside the pool body is connected to the tubular aerator part through a connecting pipe; The tubular aerator part includes a tubular aerator, and several tubular aerators are evenly distributed in a circular array; The rotating part includes a motor. The motor is connected to a rotating shaft, the rotating shaft is connected to the tubular aerator part, the motor is installed on a support crossbeam, and the support crossbeam is installed above the pool body.

[0006] Further: The support crossbeam is a stainless steel square pipe.

[0007] Further: The tubular aerator is selected as an L-shaped tubular aerator. A number of such tubular aerators are provided and are evenly distributed, and are connected by an intermediate disc.

[0008] Further: The rotating shaft penetrates through the support cross beam and is connected to the intermediate disc.

[0009] Further: When the motor starts, it drives the rotating shaft to rotate, and the rotating shaft drives a part of the tubular aerator to rotate.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: In the present invention, the aeration branch pipes extend along the pool wall to the bottom of the pool. The bottom end of the pool is connected to the tubular aerator through a connecting pipe. The tubular aerator is selected as a number of L-shaped tubular aerators, which are evenly distributed and connected into a whole through an intermediate disc. The rotating shaft of the rotating part penetrates through the support cross beam and extends to the bottom of the pool to be connected to the intermediate disc. When the motor operates, it drives the rotating shaft to rotate, realizing the rotation of a part of the tubular aerator. Combining with the opening degree of the regulating valve, air enters the connecting pipe through the aeration branch pipes, and then enters the intermediate disc, and spreads into the pool through the tubular aerator, so that the air is fully mixed with the sewage, improving the aeration efficiency. The rotating tubular aerator can stir the sewage at the bottom of the pool, solving the problem of sludge deposition at the bottom of the pool. Description of the Drawings

Detailed Embodiments

[0013] In order to enable those skilled in the art to better understand and implement the technical solutions of the present invention, the following further illustrates the present invention in combination with specific embodiments. However, the specific embodiments cited are only for the illustration of the present invention and do not limit the present invention.

[0014] Such as Figure 1A rotatable tube aerator as shown, comprising an aeration pipe part, a tube aerator part, and a rotating part. The aeration pipe part includes an aeration branch pipe 1, a regulating valve 2, and a connecting pipe 3. The tube aerator part includes a tube aerator 4 and an intermediate disc 5. The rotating part includes a motor 6, a support cross beam 7, and a rotating shaft 8.

[0015] The regulating valve 2 is installed at one end of the aeration branch pipe 1 outside the pool body for adjusting the air volume of the aeration branch pipe 1. The aeration branch pipe is connected to the aeration main pipe through the regulating valve (the aeration main pipe is not shown in the figure). The aeration branch pipe 1 extends along the pool wall (the pool refers to the aeration pool) into the bottom of the pool and is connected to the tube aerator part through the connecting pipe 3. As Figure 2 shown: The tube aerator 4 part is composed of six uniformly distributed L-shaped tube aerators 4 evenly distributed with the center of the intermediate disc 5 as the center point, and the included angle is 60 degrees.

[0016] The support cross beam 7 is installed at the upper end of the pool body, and the motor 6 is installed on the support cross beam 7 as a structural support to ensure the stable and reliable operation of the entire device and enhance the positioning effect of the device, so that each L-shaped tube aerator can aerate evenly and ensure the stable treatment effect of the aeration pool. The output shaft of the motor 6 is equipped with a rotating shaft 8. The rotating shaft 8 passes through the support cross beam 7 and is connected to the intermediate disc 5 that makes up the tube aerator part. When the motor 6 is started, it drives the rotating shaft 8 to rotate to realize the rotation of the entire tube aerator part.

[0017] The regulating valve 2 is selected as a double union ball valve, which is convenient for adjusting the air volume of aeration and also convenient for the maintenance and replacement of the equipment.

[0018] During use: Start the motor 6, drive the tube aerator part 4 to rotate by the rotating shaft 8, and at the same time open the regulating valve 2 to an appropriate opening. Air enters the connecting pipe 3 from the aeration branch pipe 1, then enters the intermediate disc 5 and finally reaches the six uniformly distributed L-shaped tube aerators 4. Thus, the gas spreads upward in a spiral shape. On the one hand, it can make the air fully mix with the sewage and increase the aeration efficiency. On the other hand, the six L-shaped tube aerators can greatly stir the sewage at the bottom of the pool, effectively avoiding the problem of sediment accumulation at the bottom of the pool.
