Abstract

This invention belongs to the field of wastewater treatment technology, specifically an aeration system including an oxygen mixing device. The inner wall of the oxygen mixing device is uniformly equipped with liquid delivery devices, and a filter grid is installed at the bottom of the liquid delivery devices. The oxygen mixing device includes a waterproof bottom tank, and a supporting partition is fixedly connected to the middle of the inner wall of the waterproof bottom tank.

Description

Technical Field

[0001] This invention belongs to the field of wastewater treatment technology, specifically an aeration system. Background Technology

[0002] Industrial wastewater contains a large amount of organic matter, which poses potential hazards to the environment and human health. Therefore, during the treatment of industrial wastewater, it passes through a corresponding aeration system. This system adds a large amount of oxygen to the wastewater, prompting microorganisms in the aerobic tank to convert the organic matter in the wastewater into inorganic substances such as carbon dioxide and water. This process achieves the goal of microbial cleanup of organic matter in wastewater, resulting in a green and environmentally friendly treatment.

[0003] Because wastewater can clog the nozzles of the aeration system, more and more aeration devices are being equipped with protective devices such as bar screens to prevent external impurities from entering the aeration device's mesh and interior. However, ordinary bar screens are also prone to clogging after prolonged use, and once the bar screen is clogged, the water inlet of the aeration system will also be blocked, resulting in the system only absorbing oxygen but not spraying water, which leads to a significant decrease in actual working efficiency. Therefore, improvements are needed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this invention to solve its technical problems is: an aeration system, including an oxygen mixing device, wherein an infusion device is uniformly arranged on the inner wall of the oxygen mixing device, and a filter grid is arranged at the bottom of the infusion device;

[0005] The oxygen mixing equipment includes a waterproof bottom box. A supporting partition is fixedly connected to the middle of the inner wall of the waterproof bottom box. A bidirectional torque motor is fixedly connected to the axis of the inner cavity of the supporting partition. A torque shaft is fixedly connected to the top of the output shaft of the bidirectional torque motor. A rotating push plate is fixedly connected to the top of the torque shaft. A stirring rod is fixedly connected to the axis of the upper surface of the rotating push plate. An inclined water-cutting plate is arranged on the outer surface of the stirring rod. When the stirring rod is rotated, the water and oxygen can be dispersed, thereby mixing the oxygen into the water. A sloping trough water outlet cover is rotatably connected to the top of the stirring rod. Water is sprayed out through the trough opening of the sloping trough water outlet cover. Since the trough opening is sloping, the problem of the device being unstable due to the reaction force caused by direct water spray is avoided. A diversion tube is fixedly connected to the bottom of the sloping trough water outlet cover. Oxygen supply pipes are evenly arranged at the bottom of the inner cavity of the diversion tube.

[0006] The infusion device includes a rigid plate, the structure of which is as follows: Figure 4As shown, the device is a hollow, elongated plate that can transport sewage from bottom to top into the interior of the diversion tube. A compression tube is evenly arranged in the middle of the inner cavity of the rigid plate. A diversion end is fixedly connected to the top of the rigid plate, with its inlet located in the middle of the right side. Sewage is sprayed into the interior of the diversion tube from nozzles on both the upper and lower sides through the diversion end's inner wall. Buffer springs are symmetrically arranged on the upper and lower sides of the diversion end. A grooved disc is fixedly connected to the bottom of the rigid plate, and a solid filter element is fixedly connected to the axis of the grooved disc's inner cavity. Return spring bands are evenly arranged in the middle of the inner wall of the grooved disc.

[0007] Furthermore, the number of infusion devices is four. The outer surface of the diversion end is slidably connected to the middle of the inner wall of the drainage tube through a through groove. One end of the buffer spring is fixedly connected to the inner cavity of the diversion end, and the other end of the buffer spring is fixedly connected to the inner wall of the drainage tube. One end of the compression tube is fixedly connected to the outer surface of the waterproof bottom box, and the other end of the compression tube is fixedly connected to the middle of the inner cavity of the rigid plate through a through port.

[0008] Furthermore, a drainage groove is provided at the bottom of the inner cavity of the rigid plate, and the top of the solid filter element extends into the interior of the rigid plate through the drainage groove. The middle part of the inner wall of the grooved disc is slidably connected to the bottom of the inner cavity of the waterproof base box through a through-hole. The end of the reset spring band away from the solid filter element is fixedly connected to the inner cavity of the waterproof base box through the through-hole.

[0009] Furthermore, the lower part of the inner wall of the waterproof tank is evenly provided with adjusting bases through through slots, and the bottom of the adjusting bases is fixedly connected to the bottom of the tank. There are two adjusting bases, and the bottom end of the output shaft of the bidirectional torque motor extends to the outside of the waterproof tank. The adjusting bases are as follows... Figure 2 As shown, it is divided into a fixed part at the bottom and a supporting part at the top. The waterproof bottom box can be lifted up by the supporting part, which can adjust the actual depth of the device in the sewage tank.

[0010] Furthermore, the filter grid plate includes a circular rotating shell, the inner cavity of which is uniformly provided with vertical grooves, and the inner cavity of the circular rotating shell is uniformly provided with filter screens through the vertical grooves. The top of the inner wall of the circular rotating shell is rotatably connected to a connecting sleeve, and the bottom of the connecting sleeve is uniformly provided with friction balls through a fixing ring. The connecting sleeve is used to seal the gap between the circular rotating shell and the waterproof bottom box, and to provide traction force for the circular rotating shell.

[0011] Furthermore, the upper surface of the circular rotating shell is uniformly provided with embedded protrusions, and the lower surface of the waterproof bottom box is uniformly provided with mating round head rods. The top of the embedded protrusions and the bottom of the mating round head rods are pressed against each other, and the bottom of the bidirectional torque motor output shaft is fixedly connected to the axis at the bottom of the inner wall of the circular rotating shell.

[0012] Furthermore, the top of the connecting sleeve is fixedly connected to the axis at the bottom of the outer surface of the waterproof base box, the outer surface of the friction ball is rolledly connected to the top of the inner cavity of the circular rotating shell through the built-in slide rail, and the outer surface of the filter screen is inserted into the inner cavity of the circular rotating shell through the vertical groove. Each filter screen is inserted into the groove of the circular rotating shell, so the filter screen can be replaced by removing it.

[0013] Furthermore, the rotating pusher includes a counterweight shell, a pressure-sensing ring is fixedly connected to the center of the inner cavity of the counterweight shell, guide rails are evenly provided in the inner cavity of the counterweight shell, a flat wheel is slidably connected to the inner wall of the guide rail, a bearing sleeve is rotatably connected to the center of the inner wall of the flat wheel, and the outer surface of the bearing sleeve is fixedly connected to the outer surface of the pressure-sensing ring through a spring rod. When the rotating pusher rotates, it will push the center of the diversion end to the outside through the outer protruding flat wheel, thereby pushing the entire rigid plate to slide outward.

[0014] Furthermore, the number of flat rollers is four, the outer surface of the flat rollers is slidably connected to the inner wall of the counterweight disc shell through a guide rail, the outer surface of the flat rollers is pressed against the middle of the outer surface of the diverter end, and the inner wall of the bearing sleeve is rotatably connected to the middle of the inner wall of the flat rollers.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. When using this device, sewage can be pumped from bottom to top using four sets of infusion equipment. Since the lower filter plate has been used for filtration beforehand, and the circular rotating shell will continuously vibrate at high frequency in the sewage tank with the bidirectional torque motor during operation, the impurities attached to the filter screen are easily shaken off, thereby achieving the effect of clearing the filter screen opening.

[0017] 2. The grooved disc and the waterproof base box of the device are always in a relative sliding state, but the grooved disc will not separate from the waterproof base box. The wide covers on both sides of the grooved disc will also have a waterproof effect on the through-hole at the bottom of the waterproof base box. Therefore, the grooved disc will not solidify on the waterproof base box due to long-term operation, which would cause the bottom of the rigid plate to be stuck and thus make it difficult to move.

[0018] 3. When the four infusion devices are in operation, they slide relative to the drainage tube due to the pushing force of the rotating push plate and the elastic force of its own spring. The moving rigid plate can not only shake off the impurities attached to the solid filter element at the bottom, but also squeeze out the impurities blocked inside the solid filter element and the diversion end from the inside through the pressurization effect of the compressed tube, thus ensuring that the rigid plate is always in a relatively unobstructed state.

[0019] 4. When the counterweight disc rotates, the flat rollers on the inner wall of the guide rail directly compress the solid part in the middle of the diversion end. At this time, the flat rollers will also slide inward along the guide rail due to the reaction force of the compression, and compress the pressure-sensing ring through the spring rod. When the diversion end is stuck in the diversion tube and the hard plate is difficult to push, the flat rollers will completely retract inside the counterweight disc. At this time, the pressure-sensing ring is subjected to excessive compression force, thus detecting the abnormal condition. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0029] Example 1, please refer to Figures 1-5 The present invention provides a technical solution: an aeration system, including an oxygen mixing device 1, an infusion device 2 uniformly arranged on the inner wall of the oxygen mixing device 1, and a filter grid 3 arranged at the bottom of the infusion device 2;

[0030] The oxygen mixing device 1 includes a waterproof bottom box 11. A support partition 12 is fixedly connected to the middle of the inner wall of the waterproof bottom box 11. A bidirectional torque motor 13 is fixedly connected to the axis of the inner cavity of the support partition 12. A torque shaft 14 is fixedly connected to the top of the output shaft of the bidirectional torque motor 13. A rotating push plate 5 is fixedly connected to the top of the torque shaft 14. A stirring rod 17 is fixedly connected to the axis of the upper surface of the rotating push plate 5. An inclined water-cutting plate is arranged on the outer surface of the stirring rod 17. When the stirring rod 17 is rotated, the water and oxygen can be dispersed, thereby achieving the effect of mixing oxygen into the water. An inclined trough water outlet cover 18 is rotatably connected to the top of the stirring rod 17. Water is sprayed out through the trough opening of the inclined trough water outlet cover 18. Since the trough opening is inclined, the problem of the device body being unstable due to the reaction force caused by direct water spray is avoided. A diversion tube 16 is fixedly connected to the bottom of the inclined trough water outlet cover 18. Oxygen supply pipes 15 are evenly arranged at the bottom of the inner cavity of the diversion tube 16.

[0031] Infusion device 2 includes a rigid plate 21, the structure of which is as follows: Figure 4 As shown, it is a hollow strip plate that can transport sewage from bottom to top into the interior of the diversion tube 16. A compression tube 22 is evenly arranged in the middle of the inner cavity of the rigid plate 21. A diversion end 23 is fixedly connected to the top of the rigid plate 21. The inlet of the diversion end 23 is located in the middle of the right side. Through the diversion effect of the inner wall of the diversion end 23, sewage is sprayed into the interior of the diversion tube 16 from the nozzles on the upper and lower sides. Buffer springs 24 are symmetrically arranged on the upper and lower sides of the diversion end 23. A grooved disc 26 is fixedly connected to the bottom of the rigid plate 21. A solid filter element 27 is fixedly connected to the axis of the inner cavity of the grooved disc 26. A reset spring band 28 is evenly arranged in the middle of the inner wall of the grooved disc 26.

[0032] There are four infusion devices 2. The outer surface of the diversion end 23 is slidably connected to the middle of the inner wall of the drainage tube 16 through the through groove. One end of the buffer spring 24 is fixedly connected to the inner cavity of the diversion end 23, and the other end of the buffer spring 24 is fixedly connected to the inner wall of the drainage tube 16. One end of the compression tube 22 is fixedly connected to the outer surface of the waterproof bottom box 11, and the other end of the compression tube 22 is fixedly connected to the middle of the inner cavity of the rigid plate 21 through the through hole.

[0033] A drainage groove 25 is provided at the bottom of the inner cavity of the rigid plate 21. The top of the solid filter element 27 extends into the interior of the rigid plate 21 through the drainage groove 25. The middle part of the inner wall of the grooved disc 26 is slidably connected to the bottom of the inner cavity of the waterproof base box 11 through the through hole. The end of the reset spring band 28 away from the solid filter element 27 is fixedly connected to the inner cavity of the waterproof base box 11 through the through hole.

[0034] Two adjustment bases 4 are evenly arranged on the lower part of the inner wall of the waterproof bottom tank 11 through a through-cut groove. The bottom of the adjustment base 4 is fixedly connected to the bottom of the tank. The bottom end of the output shaft of the bidirectional torque motor 13 extends to the outside of the waterproof bottom tank 11. The adjustment bases 4 are as follows: Figure 2 As shown, it is divided into a fixed part at the bottom and a supporting part at the top. The waterproof bottom box 11 can be lifted upward by the supporting part, so that the actual depth of the device in the sewage tank can be adjusted.

[0035] Before using the device for aeration, install the device at the bottom of the sewage tank. After fixing the bottom of the adjusting base 4 to the bottom of the tank, adjust the actual height of the mixing equipment 1 through the adjusting base 4 at the bottom, and then continuously input air into the inside of the diversion cylinder 16 through the four oxygen supply pipes 15.

[0036] The bidirectional torque motor 13 is started, and the sewage is driven to flow from bottom to top through the filter screen 3 by twisting the stirring rod 17. Then the sewage is sprayed out through the inclined groove of the inclined groove outlet cover 18. As the sewage passes through the position of the stirring rod 17, it will mix with the air input by the oxygen supply pipe 15. The air forms finer bubbles that mix into the interior of the sewage, thereby increasing the oxygen content in the sewage.

[0037] The rotating pusher 5 rotates continuously with the stirring rod 17. At this time, the rotating pusher 5 pushes the solid position in the middle of the diversion end 23 around the perimeter through the protruding part on the side, thereby pushing open the rigid plate 21 and causing the rigid plate 21 to slide away from the diversion tube 16. At this time, the top of the rigid plate 21 will compress the buffer spring 24 through the diversion end 23; the middle of the rigid plate 21 will pull the compression tube 22, thereby lengthening the compression tube 22; the bottom of the rigid plate 21 will pull the grooved disc 26 to slide along the groove at the bottom of the inner cavity of the waterproof base box 11. However, the wide covers on the upper and lower sides of the grooved disc 26 always restrict the grooved disc 26 to the waterproof base box 11, so the grooved disc 26 will not detach from the waterproof base box 11. Furthermore, when the grooved disc 26 moves, the return spring band 28 on the inner wall will deform, thereby possessing the elastic potential energy to return the grooved disc 26 to its original position.

[0038] Overall, when sewage flows from the solid filter element 27 into the rigid plate 21 under the suction of the stirring rod 17, and then flows into the diversion tube 16 through both sides of the diversion end 23, the rigid plate 21 and the solid filter element 27 are constantly shaking during operation, and the compression tube 22 will further squeeze the impurities in the filter port of the solid filter element 27 downward during the compression process. Therefore, even if the sewage carries a lot of impurities, it is not easy to cause the blockage problem of the infusion equipment 2, and further reduce the phenomenon of contact wear between the stirring rod 17 and solid particles, thus enhancing the service life of the stirring rod 17.

[0039] Example 2, please refer to Figures 1-7 The present invention provides a technical solution: Based on the first embodiment, the filter plate 3 includes a circular rotating shell 31. The inner cavity of the circular rotating shell 31 is uniformly provided with vertical grooves, and the inner cavity of the circular rotating shell 31 is uniformly provided with filter screens 32 through the vertical grooves. The top of the inner wall of the circular rotating shell 31 is rotatably connected to a connecting sealing cylinder 34, and the bottom of the connecting sealing cylinder 34 is uniformly provided with friction balls 35 through a fixing ring. The connecting sealing cylinder 34 is used to seal the gap between the circular rotating shell 31 and the waterproof bottom box 11, and to provide traction for the circular rotating shell 31.

[0040] The upper surface of the circular rotating shell 31 is uniformly provided with embedded protrusions 33, and the lower surface of the waterproof base box 11 is uniformly provided with mating round head rods 36. The top of the embedded protrusions 33 and the bottom of the mating round head rods 36 are pressed against each other. The bottom of the output shaft of the bidirectional torque motor 13 is fixedly connected to the axis at the bottom of the inner wall of the circular rotating shell 31.

[0041] The top of the connecting sleeve 34 is fixedly connected to the axis at the bottom of the outer surface of the waterproof base box 11. The outer surface of the friction ball 35 is rolled to the top of the inner cavity of the circular rotating shell 31 through the built-in slide rail. The outer surface of the filter screen 32 is inserted into the inner cavity of the circular rotating shell 31 through the vertical groove. Each filter screen 32 is inserted into the groove of the circular rotating shell 31, so the filter screen 32 can be replaced by removing it.

[0042] The rotating push plate 5 includes a counterweight shell 51. A pressure-sensing ring 53 is fixedly connected to the middle of the inner cavity of the counterweight shell 51. Guide rails 52 are evenly distributed in the inner cavity of the counterweight shell 51. A flat rotating wheel 56 is slidably connected to the inner wall of the guide rail 52. A bearing sleeve 55 is rotatably connected to the middle of the inner wall of the flat rotating wheel 56. The outer surface of the bearing sleeve 55 is fixedly connected to the outer surface of the pressure-sensing ring 53 through a spring rod 54. When the rotating push plate 5 rotates, it will push the middle of the diversion end 23 outward through the outer protruding flat rotating wheel 56, thereby pushing the entire rigid plate 21 to slide outward.

[0043] There are four flat rollers 56. The outer surface of the flat rollers 56 is slidably connected to the inner wall of the counterweight disc shell 51 through the guide rail 52. The outer surface of the flat rollers 56 is pressed against the middle of the outer surface of the diverter end 23. The inner wall of the bearing sleeve 55 is rotatably connected to the middle of the inner wall of the flat rollers 56.

[0044] Wastewater first enters the bottom of the infusion device 2 through the filter screen 32 on the circular rotating shell 31. Therefore, the filter screen 32 blocks a large amount of impurities to the outside. When the bidirectional torque motor 13 is working, the bottom output shaft will continuously rotate the circular rotating shell 31. At this time, the circular rotating shell 31 rotates relative to the connecting sleeve 34 with the assistance of the friction ball 35. When the embedded protrusion 33 on the top of the circular rotating shell 31 is squeezed against the docking round head rod 36 at the bottom of the waterproof bottom box 11, the connecting sleeve 34 is stretched. The circular rotating shell 31 slides down a certain distance due to the thrust. Then, when the embedded protrusion 33 separates from the docking round head rod 36, the connecting sleeve 34 pulls the circular rotating shell 31 back up to its original position. Therefore, the circular rotating shell 31 continuously vibrates at a high frequency in the vertical direction during operation, thereby shaking off the impurities attached to the filter screen 32 and ensuring that the mesh of the filter screen 32 can allow wastewater to pass through.

[0045] When the counterweight disc 51 rotates, the flat roller 56 on the inner wall of the guide rail 52 directly squeezes the solid part in the middle of the diversion end 23. At this time, the flat roller 56 will also slide inward along the guide rail 52 due to the reaction force of the squeeze, and squeeze the pressure ring 53 through the spring rod 54. When the diversion end 23 is stuck in the diversion tube 16 and the rigid plate 21 is difficult to push, the flat roller 56 will completely retract inside the counterweight disc 51. At this time, the pressure ring 53 is subjected to excessive squeezing force, thus detecting an abnormal condition.

[0046] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
