Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment technology, and in particular to a mixed aeration device for industrial wastewater treatment. Background Technology

[0002] Wastewater treatment equipment is an industrial device that can effectively treat domestic sewage and industrial wastewater in urban areas, preventing sewage and pollutants from flowing directly into water bodies. It is of great significance for improving the ecological environment, enhancing the city's image, and promoting economic development. In wastewater treatment, aeration refers to the artificial introduction of air into the biological aeration tank through appropriate equipment to achieve the desired purpose. Aeration has the purpose of preventing suspended solids in the tank from settling and enhancing the contact between organic matter, microorganisms, and dissolved oxygen in the tank.

[0003] In the process of industrial wastewater treatment, mixed aeration is a crucial step. Through mixed aeration, pollutants in the wastewater can come into full contact with activated sludge and microorganisms, promoting the decomposition and oxidation of pollutants by microorganisms, thereby purifying the wastewater. However, existing industrial wastewater mixed aeration devices have many problems. Traditional devices are mostly fixed installations with no height adjustment, making it difficult to adapt to wastewater pools of different depths. When the wastewater pool is shallow, parts of the device may be submerged too deeply in the wastewater, affecting operation and equipment stability. When the wastewater pool is deep, the device cannot effectively act on the deep wastewater, resulting in insufficient mixing and aeration, and reducing the wastewater treatment effect. To address these issues, we propose a mixed aeration device for industrial wastewater treatment. Utility Model Content

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.

[0023] Please see Figure 1-4 In this utility model, a mixing aeration device for industrial wastewater treatment includes a square frame 1. A support member 5 is fixedly installed on the outer surface of the square frame 1. A reduction motor 7 is fixedly installed on the upper surface of the square frame 1. A lead screw 8 is fixedly connected to the output end of the reduction motor 7. A screw plate 9 is threadedly connected to the outer surface of the lead screw 8. Two sliding pillars 13 are fixedly connected to the inner wall of the square frame 1. A transmission plate 11 is slidably connected to the outer surface of each sliding pillar 13, and the transmission plate 11 is fixedly connected to the screw plate 9. A transmission square rod 12 is fixedly connected to the bottom surface of each transmission plate 11. A connecting frame 6 is fixedly connected to the bottom end of the two transmission square rods 12. A square box 2 is fixedly connected to the bottom surface of the connecting frame 6. The mixing component 3 is fixedly installed inside the connecting frame 6, and the aeration component 4 is fixedly installed inside the connecting frame 6. The square frame 1 provides support for the whole. The geared motor 7, the lead screw 8, and the screw plate 9 form a height adjustment drive mechanism. The transmission plate 11 and the transmission square rod 12 realize the height transmission. The mixing component 3 and the aeration component 4 respectively complete the functions of sewage mixing and aeration. All parts work together to achieve effective treatment of sewage at different depths. The geared motor 7 can be started, which drives the lead screw 8 to rotate. The screw plate 9 moves downward on the lead screw 8. Through the transmission plate 11 and the transmission square rod 12, the connecting frame 6 and the square box 2 are lowered, and the mixing component 3 and the aeration component 4 are adjusted to a suitable depth to adapt to the use of sewage tanks of different depths.

[0024] Support component 5 includes two sliding cylinders 501 fixedly installed on the outer surface of the square frame 1. Each sliding cylinder 501 has a sliding rod 502 slidably connected inside. Each sliding rod 502 has a mounting seat 503 with an opening fixedly connected to its outer surface. Each sliding cylinder 501 also has a plate 504 with an opening fixedly connected to its outer surface. The sliding cylinders 501, sliding rods 502, and mounting seats 503 of support component 5 can be flexibly adjusted in their installation positions according to the actual conditions at the edge of the sewage tank. The plate 504 with an opening can assist in fixing the sliding rods 502, ensuring the device is stably installed at the edge of the sewage tank and providing a stable foundation for the device's operation. Aeration component 4 includes a blower 401 fixedly installed on the upper surface of the square box 2. The exhaust end of the blower 401 is fixedly connected to a three-way air guide pipe 402. The two ends of the three-way air guide pipe 402... Each exhaust end is fixedly connected to an aeration pipe 404. When the blower 401 is started, air is diverted through the three-way air guide pipe 402 to the two aeration pipes 404. The aeration pipes 404 release air into the wastewater in the form of bubbles. When treating industrial wastewater containing organic pollutants, sufficient dissolved oxygen promotes the activity of microorganisms, accelerates the decomposition of organic pollutants, and improves the wastewater treatment effect. Two connecting plates 403 are fixedly connected to the outer surface of the three-way air guide pipe 402. The outer surface of each connecting plate 403 is fixedly connected to the outer surface of the square box 2. The connecting plates 403 fix the three-way air guide pipe 402 to the square box 2, which enhances the stability of the aeration component 4 structure and prevents the aeration pipes 404 from shifting or loosening due to airflow impact or vibration during the aeration process, ensuring the stable operation of the aeration system.

[0025] The mixing component 3 includes a rotary motor 301 fixedly installed on the inner wall of the square box 2. The output end of the rotary motor 301 is fixedly connected to a main rotating rod 303. A main sprocket 302 is fixedly connected to the outer surface of the main rotating rod 303. A secondary rotating rod 304 is rotatably connected to the inner wall of the square box 2 through bearings. Multiple stirring rods 307 and multiple stirring blades 308 are fixedly connected to the outer surfaces of the secondary rotating rod 304 and the main rotating rod 303. A secondary sprocket 305 is fixedly connected to the outer surface of the secondary rotating rod 304. The main sprocket 302 is connected to the secondary sprocket 305 through a transmission chain 306. The rotary motor 301 of the mixing component 3 drives the main rotating rod 303 and the secondary rotating rod 304 to rotate synchronously through the main sprocket 302, the transmission chain 306 and the secondary sprocket 305. The stirring rods 307 and the stirring blades 308 stir the sewage from multiple directions, so that the agents and pollutants in the sewage can fully contact and react, thereby improving the mixing uniformity and sewage treatment efficiency.

[0026] Example: After adding flocculants and other treatment agents to the wastewater tank, the rotary motor 301 is started. The motor drives the main rotating rod 303 to rotate, and the main sprocket 302 drives the secondary sprocket 305 through the transmission chain 306, causing the secondary rotating rod 304 to rotate synchronously. The stirring rod 307 and stirring blades 308 rapidly agitate the wastewater, causing the flocculant to quickly disperse to various areas of the wastewater, react fully with the pollutants, and form larger flocs, which facilitate subsequent sedimentation and separation, thereby improving the purification effect of wastewater treatment.

[0027] Each transmission plate 11 has a side connecting column 10 fixedly connected to its outer surface. The bottom end of each side connecting column 10 passes through the square frame 1 and is fixedly connected to the outer surface of the square box 2. The side connecting column 10 connects the transmission plate 11 and the square box 2, which enhances the structural stability of the device during height adjustment and operation, prevents the square box 2 from shaking during stirring and aeration, ensures the stable operation of the mixing component 3 and the aeration component 4, and improves the reliability of sewage treatment.

[0028] The working principle of this utility model is as follows:

[0029] During installation, the mounting base 503 with an opening is fixed at a suitable position on the side of the sewage tank. The sliding support cylinder 501 is adjusted to slide along the sliding rod 502, and the square frame 1 is fixed in a suitable installation position by the plate with an opening 504. Then, the reduction motor 7 is started according to the depth of the sewage tank. The operation of the reduction motor 7 drives the lead screw 8 to rotate, and the screw plate 9 moves downward on the lead screw 8. The connecting frame 6 and the square box 2 are lowered through the transmission plate 11 and the transmission square rod 12, and the mixing component 3 and the aeration component 4 are adjusted to a suitable depth. Finally, the rotary motor 301 is started, which drives the main rotating rod 303 and the auxiliary rotating rod 304 to rotate synchronously through the main sprocket 302, the transmission chain 306 and the secondary sprocket 305. The stirring rod 307 and the stirring blade 308 stir the sewage in multiple directions to achieve full mixing of the sewage. The blower 401 of the aeration component 4 introduces air into the sewage through the three-way air guide pipe 402 and the aeration pipe 404 to increase the dissolved oxygen content in the water and improve the sewage treatment effect.
