Description

A rotatable tubular aerator Technical Field

[0001] This utility model belongs to the field of aeration devices in sewage treatment, and specifically relates to a rotatable tubular aerator. Background Technology

[0002] In wastewater treatment, aeration refers to the introduction of air into a biological aeration tank using appropriate equipment to achieve the desired effect. Aeration not only brings oxygen into the tank by contacting the liquid with air, but also accelerates the transfer of oxygen from the air into the liquid due to liquid agitation, thus achieving the purpose of oxygenation. Furthermore, aeration prevents suspended solids from settling and enhances the contact between organic matter and microorganisms with dissolved oxygen, thereby ensuring that microorganisms in the tank can oxidize and decompose organic matter in the wastewater under conditions of sufficient dissolved oxygen. The quality of the aeration device not only affects the biological treatment effect of wastewater but also directly impacts the land area, investment, and operating costs of the treatment plant. A blower aeration device mainly consists of an aeration blower, connecting pipes, and aerators.

[0003] Current aerators are typically installed at the bottom of the tank. During aeration, the gas mixes thoroughly with the wastewater as it rises, completing the oxygenation process for the entire water body. However, traditional aerators suffer from uneven aeration distribution and are prone to sludge deposition at the bottom. Therefore, the applicant has purposefully developed a rotatable tubular aerator that accelerates gas-sewage mixing, improves aeration efficiency, and the rotating aeration tube stirs up the wastewater at the bottom, preventing sludge deposition. Summary of the Invention

[0004] The purpose of this utility model is to solve the above-mentioned problems. This application proposes a rotatable tubular aerator, which can accelerate the mixing of gas and sewage, improve aeration efficiency, and the rotating aeration pipe can stir the sewage at the bottom of the pool, avoiding the problem of sludge deposition at the bottom of the pool.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a rotatable tubular aerator, comprising an aeration pipe section, a tubular aerator section, and a rotating section. The aeration pipe section includes an aeration branch pipe, which extends along the pool wall into the bottom of the pool, with one end located inside the pool and the other end located outside the pool. The aeration branch pipe located outside the pool is provided with a regulating valve, and the aeration branch pipe located inside the pool is connected to the tubular aerator section through a connecting pipe.

[0006] The tubular aerator section includes several tubular aerators, which are evenly distributed in a circular array.

[0007] The rotating part includes a motor, which is connected to a rotating shaft. The rotating shaft is connected to a tubular aerator. The motor is mounted on a support beam, which is mounted above the tank.

[0008] Furthermore: the supporting beams are made of stainless steel square tubing.

[0009] Furthermore: the tubular aerator is an L-shaped tubular aerator, and there are several tubular aerators, which are evenly distributed and connected by a central disc.

[0010] Furthermore: the rotating shaft passes through the supporting crossbeam and connects to the intermediate disk.

[0011] Furthermore: the motor starts and drives the rotating shaft to rotate, and the rotating shaft drives the tubular aerator part to rotate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This utility model relates to an aeration branch pipe that extends along the tank wall to the bottom of the tank. The bottom end of the pipe is connected to a tubular aerator via a connecting pipe. Several L-shaped tubular aerators are selected and evenly distributed, connected as one unit by a central disc. The rotating shaft of the rotating part extends through the supporting beam to the bottom of the tank and connects to the central disc. When the motor runs, it drives the rotating shaft to rotate, thereby rotating the tubular aerator. Combined with the opening of the regulating valve, air is introduced through the aeration branch pipe into the connecting pipe, and then into the central disc. The air then spreads into the tank through the tubular aerator, allowing the air and sewage to fully mix, improving aeration efficiency. The rotating tubular aerator can also agitate the sewage at the bottom of the tank, solving the problem of sludge deposition at the bottom of the tank. Attached Figure Description

[0018] To enable those skilled in the art to better understand and implement the technical solution of this utility model, the present utility model will be further described below with reference to specific embodiments. However, the embodiments described are only for illustration and are not intended to limit the present utility model.

[0019] As shown in Figure 1, a rotatable tubular aerator includes an aeration pipe section, a tubular aerator section, and a rotating section. The aeration pipe section includes an aeration branch pipe 1, a regulating valve 2, and a connecting pipe 3. The tubular aerator section includes a tubular aerator 4 and an intermediate disc 5. The rotating section includes a motor 6, a support beam 7, and a rotating shaft 8.

[0020] The regulating valve 2 is installed on the end of the aeration branch pipe 1 located outside the tank body. It is used to regulate 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 tank wall (the tank refers to the aeration tank) into the bottom of the tank and is connected to the tubular aerator part through the connecting pipe 3.

[0021] As shown in Figure 2, the tubular aerator 4 consists of six evenly distributed L-shaped tubular aerators 4, with the center of the central disc 5 as the center point, and the included angle is 60 degrees.

[0022] The support beam 7 is installed at the upper end of the tank body, and the motor 6 is installed on the support beam 7 as a structural support to ensure the stability and reliability of the entire device and enhance the positioning effect of the device, so that each L-shaped tubular aerator can aerate evenly and ensure the stable treatment effect of the aeration tank.

[0023] The output shaft of the motor 6 is equipped with a rotating shaft 8. The rotating shaft 8 passes through the support beam 7 and is connected to the middle disc 5 that makes up the tubular aerator. When the motor 6 is started, it drives the rotating shaft 8 to rotate, thereby realizing the rotation of the entire tubular aerator.

[0024] The regulating valve 2 is a double-ruler ball valve, which facilitates the adjustment of the aeration air volume and also makes it convenient for equipment maintenance and replacement.

[0025] In use: Start motor 6, which drives the tubular aerator section 4 to rotate via rotating shaft 8. At the same time, open regulating valve 2 to a suitable opening. Air enters connecting pipe 3 through aeration branch pipe 1, then enters the central disc 5, and finally reaches the six evenly distributed L-shaped tubular aerators 4. As a result, the gas spreads upward in a spiral shape, which on the one hand allows the air to fully mix with the sewage, increasing aeration efficiency, and on the other hand, the six L-shaped tubular aerators can greatly agitate the sewage at the bottom of the pool, effectively avoiding the problem of sludge accumulation at the bottom of the pool.

[0027] It should be noted that the above description describes the configuration of a single aerator. Without departing from the technical principles of this application, those skilled in the art can combine the technical solutions in the above embodiments, or make equivalent changes or substitutions to the relevant technical features. Any changes or equivalent substitutions made within the technical concept and / or technical principles of this application will fall within the protection scope of this application.
