Description

Technical Field

[0001] The utility model relates to the technical field of aeration branch pipes, in particular to an aeration branch pipe assembly provided with an electric butterfly valve. Background Technique

[0002] The aeration branch pipe is a key component in the water treatment system for transporting air to the aerator. Its function is to evenly distribute air to each aeration point to achieve oxygenation and agitation of sewage, ensure that air can be evenly distributed throughout the aeration area, avoid insufficient local oxygen supply, connect the main air pipe and each aerator to form a complete air transportation network, and through the design on the branch pipe, the air flow rate can be adjusted to adapt to different aeration requirements. Usually, corrosion-resistant and wear-resistant materials such as PVC, stainless steel or high-density polyethylene are used. The diameter of the branch pipe is determined according to the air flow rate and pressure loss. The layout of the branch pipe should consider the uniformity of air distribution and the convenience of system maintenance.

[0003] In the linear stage, when the exhaust direction directly hits the bottom of the pool, the strong air flow directly impacting the bottom of the pool may disturb the sediment, causing the pollutants at the bottom of the pool to resuspend, affecting water quality. The strong air flow may impact the microbial community, affecting its biodegradation activity. If the air flow directly impacts the bottom of the pool, it may lead to a decrease in the utilization rate of air, thereby increasing energy consumption. The long-term strong air flow may accelerate the wear of the branch pipe and the aerator, shortening the service life of the equipment. Therefore, an aeration branch pipe assembly provided with an electric butterfly valve is proposed to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide an aeration branch pipe assembly provided with an electric butterfly valve, which has the advantages of improving the efficiency of the aeration system, reducing energy consumption, and protecting the microbial activity in the water treatment process, and solves the problems of reduced aeration efficiency, increased energy consumption and affected biodegradation activity caused by air directly hitting the bottom of the pool.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an aeration branch pipe assembly provided with an electric butterfly valve, including a communicating branch pipe, and an air injection pipe is communicatively installed at the center of the lower end surface of the communicating branch pipe. It also includes an exhaust pipe;

[0007] Wherein, the bottom end of the exhaust pipe is communicatively installed with a nozzle;

[0008] Wherein, a guide frame is fixedly installed at the bottom of the nozzle.

[0009] When using an aeration branch pipe assembly provided with an electric butterfly valve in the technical solution, open the control butterfly valve to allow air to enter the system through the air inlet pipe. According to the required aeration volume, adjust the opening degree of the control butterfly valve to control the air flow rate. Air enters the connecting branch pipe through the air injection pipe to form air flow between the inner ring pipe and the outer ring pipe. Air enters the exhaust pipe through the annular array openings on the lower end faces of the inner ring pipe and the outer ring pipe, and is finally ejected through the nozzle. The guide frame at the bottom of the nozzle ensures that the air is ejected in the correct direction to achieve aeration. If necessary, adjust the aeration intensity by further adjusting the control butterfly valve. Check the system regularly to ensure that there is no blockage or damage, and clean or replace parts as needed. After the aeration process is completed, close the control butterfly valve to cut off the air supply.

[0010] Preferably, the connecting branch pipe comprises an inner ring pipe and an outer ring pipe, and the inner ring pipe and the outer ring pipe are connected and installed via the connecting pipe.

[0011] The design of the inner and outer ring tubes provides better air distribution and helps improve aeration efficiency.

[0013] Preferably, the lower end surfaces of the inner ring tube and the outer ring tube are respectively provided with annular array openings and are connected and installed with the exhaust pipe.

[0014] The annular array opening design on the lower end surfaces of the inner ring tube and the outer ring tube increases the gas-liquid contact area, which helps to improve the oxygen transfer efficiency.

[0015] The direct connection design between the opening and the exhaust pipe simplifies the structure and reduces pressure loss.

[0016] Preferably, the connecting pipe adopts a cross-shaped structural design, a hole is opened at the center of the lower end surface of the connecting pipe and is connected and installed with the gas injection pipe, and a mounting frame is movably mounted on the connecting pipe.

[0017] The cross-shaped structure design of the connecting pipe helps to distribute the air flow more evenly and improve aeration efficiency.

[0018] The opening at the center of the lower end surface is connected to the air injection pipe, which helps to concentrate the air flow and enhance the aeration effect.

[0019] The movable clip-on design of the mounting bracket provides flexibility and facilitates installation and maintenance.

[0020] Preferably, one end of the gas injection pipe away from the connecting branch pipe is connected to a control butterfly valve via a reducer.

[0021] The use of reducers allows the air flow to adjust flow rate and pressure after entering the control butterfly valve, helping to optimize the aeration process.

[0022] The setting of the control butterfly valve provides a centralized control point, facilitating the adjustment of the air flow rate of the entire aeration branch pipe assembly.

[0023] Preferably, the diameter of one end of the reducing pipe close to the air injection pipe is smaller than that of the other end, and the reducing pipe is welded and installed with the air injection pipe.

[0024] The progressive diameter design of the reducing pipe helps to reduce turbulence and pressure loss during air flow.

[0025] Welded installation provides a firm and sealed connection, reducing the risk of leakage.

[0026] Preferably, the control butterfly valve adopts the structural design of an electric control butterfly valve, and an air inlet pipe is connected and installed on the side of the control butterfly valve facing away from the reducing pipe.

[0027] The design of the electric control butterfly valve enables remote control and automated operation, improving the convenience and accuracy of operation.

At the same time, a guiding frame is fixedly installed at the bottom of the nozzle. The setting of the electric butterfly valve allows for precise adjustment of the air flow rate through the electric control system, realizing the automation and precise control of the aeration process. The air injection pipe is directly connected to the center of the lower end face of the connecting branch pipe, which helps to form a good initial bubble distribution in the center of the aeration area. The design of the connecting branch pipe helps to more evenly distribute air to the entire aeration area, avoiding insufficient or excessive local oxygen supply. A nozzle is connected and installed at the bottom end of the exhaust pipe, and the design of the nozzle can improve the transfer efficiency of oxygen from the gas phase to the liquid phase.
