Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a highly efficient and energy-saving intelligent precision aeration system. Background Technology

[0002] Aeration refers to the process of forcibly transferring oxygen from the air into a liquid. Its purpose is to obtain sufficient dissolved oxygen. In addition, aeration also prevents suspended matter in the tank from settling, enhances the contact between organic matter and microorganisms and dissolved oxygen in the tank, thereby ensuring that microorganisms in the tank can oxidize and decompose organic matter in wastewater under conditions of sufficient dissolved oxygen. It is a water treatment method that allows water and air to fully contact each other to exchange gaseous substances and remove volatile substances from the water, or to allow gases to escape from the water, such as removing odors or harmful gases such as carbon dioxide and hydrogen sulfide; or to dissolve oxygen in the water to increase the dissolved oxygen concentration, so as to remove iron, manganese or promote the degradation of organic matter by aerobic microorganisms.

[0003] Traditional perforated pipes and aeration hoses produce large-diameter bubbles that rise rapidly and remain in the water for a short time, resulting in insufficient oxygen dissolution before escaping to the surface and low oxygen transfer efficiency. To compensate for this low efficiency, the aeration rate or blower pressure is often increased to meet the oxygen demand, leading to a surge in energy consumption. Utility Model Content

[0004] The present invention aims to provide a highly efficient and energy-saving intelligent precision aeration system to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A highly efficient and energy-saving intelligent precision aeration system includes an aeration tank connected to a drain pipe and an air guide pipe. One end of the air guide pipe is connected to an air pump, and the other end of the air guide pipe has an aeration port. An aeration plate is connected to the inner wall of the aeration port. An installation pipe is connected to the air guide pipe and communicates with the aeration port. A bracket is connected to the inner wall of the installation pipe, and an installation rod is rotatably connected to the bracket. A cutting blade is connected to the installation rod, and an expansion pipe is connected to the end of the installation pipe away from the air guide pipe.

[0007] Preferably, the expansion tube is connected to a mounting frame, and the mounting frame is connected to a filter screen.

[0008] Preferably, the mounting rod is rotatably connected to the mounting frame, and a cleaning brush is connected to the mounting rod, with the cleaning brush in contact with the filter screen.

[0009] Preferably, the aeration tank is connected to several sets of fixing sleeves, and the several sets of fixing sleeves are sleeved on the outside of the air guide pipe.

[0010] Preferably, the aeration tank is connected to a second support frame, the second support frame is rotatably connected to a stirring shaft, the second support frame is connected to a motor, the output end of the motor is connected to the stirring shaft, and the stirring shaft is connected to a stirring paddle.

[0011] Preferably, the stirring shaft is inclined.

[0012] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0013] (1) This technical solution can disperse gas into tiny bubbles by setting aeration plates, thereby improving oxygen transfer efficiency; the cutting blades inside the installation tube rotate under the impact of gas, further breaking the bubbles and increasing the gas-liquid contact area; the expansion tube reduces the gas flow rate and expands the airflow diffusion range, making the bubble distribution more uniform and reducing local over-exposure; the three work together to effectively improve the aeration effect and reduce energy consumption.

[0014] (2) By setting up a filter screen, suspended impurities in the aeration tank can be effectively intercepted, preventing them from entering the installation pipe, air guide pipe and other components through the expansion pipe in reverse, avoiding the cutting blades from being entangled and stuck, and the micropores of the aeration plates from being blocked, thus ensuring the stable operation of the bubble cutting and dispersion function; at the same time, the filter screen can form a certain uniform interception of the bubbles that are about to be discharged, so that the bubble group is further refined and evenly diffused into the aeration tank when passing through the filter screen, indirectly improving the gas-liquid contact efficiency, reducing the frequency of equipment maintenance caused by impurities, and extending the service life of the system.

[0015] (3) By setting up a cleaning brush, the rotational power generated when the gas impacts and cuts the blades can be used to drive the cleaning brush to continuously clean the surface of the filter screen, promptly removing sludge, flocs, and other impurities attached to the filter screen, thus avoiding problems such as increased gas flow resistance and uneven bubble diffusion caused by filter screen blockage. This self-cleaning function, which relies on the system's own power, does not require an additional drive device. It not only ensures the long-term and efficient interception function of the filter screen, but also reduces the frequency of manual disassembly and maintenance, thereby lowering the system's operating costs. At the same time, it ensures that bubbles can always diffuse evenly into the water through a clean filter screen, further improving aeration efficiency and stability.

[0016] (4) By setting a fixed sleeve, the buoyancy generated by the gas flow and the upward trend caused by the water flow impact during the aeration process can be effectively offset, avoiding the positional deviation or upward movement of the air guide pipe due to buoyancy. This ensures that the core components such as the aeration port and aeration plate are always stably in the preset aeration depth and position, ensuring the uniformity of bubble release and the accuracy of the aeration range. It also prevents local insufficient or excessive aeration caused by the floating of the air guide pipe, thereby maintaining the efficient and stable aeration effect of the system and reducing energy waste caused by positional shaking.

[0017] (5) By setting up a stirring shaft and stirring paddles, a continuous and uniform stirring effect can be formed on the water in the tank, breaking up the water stratification and allowing the bubbles generated by aeration to diffuse more evenly throughout the aeration tank under the drive of the water flow, avoiding the problem of low oxygen utilization caused by bubbles concentrating in local areas. It also promotes full contact between the water and the bubbles, accelerates the transfer of oxygen into the water, and improves aeration efficiency.

[0018] (6) By tilting the stirring shaft, the stirring paddle can generate an oblique water flow impact force when rotating. This not only expands the coverage of the stirring effect, allowing water at different depths and in different areas of the pool to be effectively stirred, avoiding blind spots in the stirring, but also uses the oblique water flow to drive the bubbles to diffuse into a wider space, reducing the situation where bubbles quickly escape from the water surface due to aggregation during the rising process, prolonging the contact time between the bubbles and the water, and improving the oxygen dissolution efficiency.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0026] like Figure 1-5The diagram illustrates a high-efficiency, energy-saving, intelligent precision aeration system, comprising an aeration tank 1 with a drain pipe 5 connected to its side wall. An air guide pipe 2 is connected to the aeration tank 1, with one end of the pipe located outside the tank and connected to an air pump 3. The other end of the pipe extends to the bottom of the aeration tank 1. Several sets of fixing sleeves 4 are connected to the inner bottom wall of the tank 1, and these sleeves are fitted onto the outside of the air guide pipe 2. The fixing sleeves 4 secure the air guide pipe 2, preventing displacement due to buoyancy or water flow impact during aeration. An aeration port 10 is located at the bottom end of the air guide pipe 2, with an aeration plate 11 connected to its inner wall. The aeration plate 11 has several sets of small holes of the same diameter. The air pump 3 delivers air through the air guide pipe 2 to the bottom of the aeration tank 1. As the air passes through the aeration port 10, the small holes on the aeration plate 11 disperse it into microbubbles, increasing the contact area between oxygen and wastewater and enhancing oxygen transfer efficiency.

[0027] like Figure 2-3 , Figure 5 As shown, an installation pipe 12 is connected to the outer wall of the air guide pipe 2, and the installation pipe 12 is connected to the aeration port 10. A bracket 13 is connected to the inner wall of the installation pipe 12, and an installation rod 14 is rotatably connected to the bracket 13. Several sets of cutting blades 19 are connected to the bottom end of the installation rod 14. An expansion pipe 15 is connected to the end of the installation pipe 12 away from the air guide pipe 2, and an installation frame 18 is connected to the top end of the expansion pipe 15. A filter screen 17 is connected to the installation frame 18. The installation rod 14 is rotatably connected to the installation frame 18, and a cleaning brush 16 is connected to the top end of the installation rod 14. The cleaning brush 16 is located above the filter screen 17 and abuts against the filter screen 17. The gas discharged from the aeration port 10 enters the installation pipe 12, impacting the cutting blades 19, which cause the installation rod 14 to rotate, further cutting the bubbles into smaller bubbles and increasing the gas-liquid contact area. When the gas passes through the expansion pipe 15, the flow rate decreases due to the increased pipe diameter, and the bubbles diffuse evenly. The filter screen 17 intercepts impurities in the sewage, preventing them from entering the air guide pipe 2 and affecting the aeration effect. At the same time, the cleaning brush 16, driven by the rotating installation rod 14, continuously cleans the filter screen 17 to prevent impurities from clogging the pores of the filter screen 17.

[0028] like Figure 1 As shown, a bracket 6 is connected to the top of the side wall of aeration tank 1. A stirring shaft 8 is rotatably connected to the bracket 6. The stirring shaft 8 is inclined relative to aeration tank 1. A motor 9 is connected to the bracket 6. The output end of the motor 9 is connected to the stirring shaft 8. A stirring paddle 7 is connected to the stirring shaft 8. The motor 9 drives the inclined stirring shaft 8 and stirring paddle 7 to rotate, generating an oblique water flow and expanding the stirring range.

[0029] The specific implementation process is as follows:

[0030] When in use, turn on the air pump 3 and adjust the air supply of the air pump 3 according to the needs of sewage quality and treatment volume to control the aeration volume; start the motor 9 and set the stirring speed so that the stirring paddle 7 can effectively stir the water; during operation, the dissolved oxygen concentration, water quality indicators and other parameters in the aeration tank 1 are monitored in real time by the online monitoring equipment, and the air supply of the air pump 3 and the speed of the motor 9 are adjusted according to the monitoring data to achieve precise aeration.
