Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an integrated wastewater treatment device. Background Technology

[0002] In the context of rapid global industrialization and urbanization, water resources are facing unprecedented challenges. On the one hand, the continuous expansion of industrial production scale results in large amounts of industrial wastewater carrying pollutants such as heavy metals and chemical agents. The turbulence generated by stirring can easily cause aeration bubbles to escape rapidly, causing serious pollution.

[0003] In wastewater treatment and other fields, mixing and aeration are key steps in the activated sludge process. They need to work together to provide oxygen for microorganisms and promote pollutant decomposition. However, in traditional technologies, mixing and aeration equipment operate independently, which not only increases equipment investment and operation and maintenance costs, but also has the problem of poor synergy: turbulent mixing can easily cause aeration bubbles to escape rapidly, resulting in low oxygen utilization; moreover, the intensity and range of aeration and mixing cannot be precisely matched, leading to localized oxygen deficiency in wastewater, uneven microbial decomposition, and limited overall treatment efficiency, affecting wastewater purification quality and cost control. Therefore, we need to propose an integrated wastewater treatment equipment. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 This utility model provides a technical solution: an integrated sewage treatment device, including a first housing 1 and a stirring shaft 2. One end of the stirring shaft 2 passes through the top center of the first housing 1 and extends into the interior of the first housing 1. The interior of the stirring shaft 2 is hollow. The first housing 1 is the core load-bearing structure of the device, providing a space for liquid and material microbial reaction, and providing a mounting base for components such as stirring components and aeration components. The stirring shaft 2 provides a mounting carrier for stirring blades 3 and cross plates 8, and can also transport the air source of the aeration components to the air outlet 12. It can also drive the stirring components to rotate under the drive of the motor 6 and the pulley group 5.

[0017] The first housing 1 is equipped with a stirring assembly for mixing the liquid, bubbles, and microorganisms in the first housing 1 to achieve uniform distribution of dissolved oxygen. The stirring assembly includes stirring blades 3 and scrapers 4. The stirring blades 3 are installed inside the first housing 1, and one end of the stirring blades 3 is installed on the surface of the stirring shaft 2. The stirring blades 3 rotate with the stirring shaft 2 to mix the liquid, bubbles, and microorganisms in the first housing 1 to achieve uniform distribution of dissolved oxygen. A pulley set 5 is installed at the top of the stirring shaft 2, and the output end of the motor 6 is installed at the other end of the pulley set 5. The pulley set 5 transmits the power of the motor 6 to the stirring shaft 2, driving the stirring shaft 2 to rotate.

[0018] A first fixing plate 7 is installed on the outside of the first housing 1. The first fixing plate 7 provides stable mounting support for the motor 6, ensuring the stability of the motor 6 during operation. The bottom of the motor 6 is installed on the top of the first fixing plate 7. The motor 6 provides power for the rotation of the stirring shaft 2 and the stirring assembly. A horizontal plate 8 is symmetrically installed on the surface of the stirring shaft 2. The end of the horizontal plate 8 away from the stirring shaft 2 is connected to one end of the scraper 4. The horizontal plate 8 fixes the scraper 4 to the stirring shaft 2, so that the scraper 4 rotates synchronously with the stirring shaft 2. The end of the scraper 4 away from the horizontal plate 8 is in contact with the inner wall of the first housing 1. The scraper 4 rotates with the stirring shaft 2 to scrape off the material attached to the inner wall of the first housing 1, avoiding the accumulation of material residue.

[0019] An aeration assembly is installed on the outside of the first housing 1 to inject air into the interior of the first housing 1 to supplement oxygen and to carry away harmful gases through rising bubbles. The aeration assembly includes an air compressor 9 and a first air inlet pipe 10. A second fixing plate 11 is installed on the outside of the first housing 1 to provide installation support for the air compressor 9 and ensure stable operation of the air compressor 9. The air compressor 9 is installed on the outside of the first housing 1 through the second fixing plate 11. The air outlet end of the air compressor 9 is connected to one end of the first air inlet pipe 10. The air compressor 9 serves as the air source supply device for the aeration assembly, generating high-pressure air and delivering it to the first air inlet pipe 10 through the air outlet end. The first air inlet pipe 10 delivers the air source generated by the air compressor 9 to the hollow interior of the stirring shaft 2. The other end of the first air inlet pipe 10 is connected to the top center of the stirring shaft 2. The surface of the stirring shaft 2 is evenly provided with downward-sloping air outlet holes 12. The air outlet holes 12 receive the air source delivered from the hollow interior of the stirring shaft 2 and spray the air source into the liquid inside the first housing 1 in the form of bubbles, while preventing liquid backflow.

[0020] The top of the first housing 1 is connected to an exhaust pipe 13, which is used to discharge the gas released after the bubbles carrying harmful gases generated by the aeration component burst, thus achieving the discharge of harmful gases. A one-way valve 14 is installed on the surface of the exhaust pipe 13, which only allows the gas in the exhaust pipe 13 to be discharged outward, preventing external air or impurities from entering the interior of the first housing 1 through the exhaust pipe 13. A support frame 15 is installed on the outside of the first housing 1, which provides support for the entire first housing 1 and other components of the equipment, so that the equipment is placed stably on the working surface. The bottom of the first housing 1 is connected to a collection pipe 16, which is used to transport the reacted material in the first housing 1 to the storage tank 18. A valve 17 is installed on the surface of the collection pipe 16, which controls the flow of material in the collection pipe 16 by opening or closing, and adjusts the material discharge speed. The bottom of the collection pipe 16 is connected to the storage tank 18, which is used to store the reacted material in the first housing 1 transported by the collection pipe 16.

[0021] A dissolved oxygen sensor 19 is installed at the bottom of the first housing 1. The dissolved oxygen sensor 19 detects the dissolved oxygen concentration of the liquid inside the first housing 1 in real time and transmits the detection data to the controller 23. An aeration pressure sensor 20 and a speed sensor 21 are installed on the surface of the stirring shaft 2. The aeration pressure sensor 20 detects the pressure of the air source inside the stirring shaft 2 in real time and transmits the pressure data to the controller 23 to reflect the air supply status of the aeration component. The speed sensor 21 detects the rotation speed of the stirring shaft 2 in real time and transmits the speed data to the controller 23 to provide feedback on the operating status of the stirring component. A plate pressure sensor 22 is installed on the surface of the scraper 4. The plate pressure sensor 22 detects the scraping pressure when the scraper 4 is in contact with the inner wall of the first housing 1 in real time and transmits the pressure data to the controller 23 to prevent excessive wear of the scraper 4 or the inner wall of the housing.

[0022] A controller 23 is mounted on the surface of the second fixed plate 11. The controller 23 is electrically connected to the dissolved oxygen sensor 19, the plate pressure sensor 22, the aeration pressure sensor 20 and the speed sensor 21 respectively. The controller 23 is also electrically connected to the motor 6 and the air compressor 9 respectively.

[0023] The controller 23 receives the dissolved oxygen concentration in the liquid inside the first housing 1 detected by the dissolved oxygen sensor 19, the scraping pressure between the scraper 4 and the inner wall of the first housing 1 detected by the plate pressure sensor 22, the air source pressure inside the stirring shaft 2 detected by the aeration pressure sensor 20, and the rotation speed of the stirring shaft 2 detected by the speed sensor 21. The controller 23 adjusts the speed of the motor 6 and the air supply of the air compressor 9 according to the data from the dissolved oxygen sensor 19.

[0024] When the dissolved oxygen concentration is lower than the set value, the air supply output of the air compressor 9 is increased and the speed of the motor 6 is increased to enhance the mixing effect. When the dissolved oxygen concentration is higher than the set value, the air supply output and the speed of the motor 6 are reduced. At the same time, the controller 23 monitors the air supply status of the aeration component based on the data of the aeration pressure sensor 20. If the pressure is abnormal, the operating parameters of the air compressor 9 are adjusted. The data of the speed sensor 21 ensures that the stirring shaft 2 is maintained within the set speed range.

[0025] The motor 6 is controlled to adjust its speed according to the data from the plate pressure sensor 22 to avoid excessive wear caused by excessive scraping pressure between the scraper 4 and the inner wall of the first housing 1. The air source generated by the air compressor 9 enters the hollow stirring shaft 2 through the first air inlet pipe 10 and is sprayed into the first housing 1 in the form of bubbles from the air outlet 12. The stirring blade 3 rotates with the stirring shaft 2 to mix the liquid bubbles and material microorganisms, so that the dissolved oxygen is evenly distributed. The scraper 4 rotates with the stirring shaft 2 to scrape off the material on the inner wall of the first housing 1. After the bubbles carrying harmful gases rise to the liquid surface and burst, they are discharged through the exhaust pipe 13 and the one-way valve 14. The reacted material can be stored in the storage tank 18 through the collection pipe 16 by opening the valve 17.
