Description

Technical Field

[0001] The present invention relates to the technical field of air suspension fans, and in particular to an air suspension fan for sewage treatment. Background Art

[0002] Air suspension fans (also known as flotation fans or air suspension compressors) for wastewater treatment are primarily used to provide gas (such as air or oxygen) during the wastewater treatment process. In biological treatment processes, particularly the activated sludge process, air suspension fans provide oxygen to the wastewater, sustaining the life activities of aerobic microorganisms and promoting their decomposition of organic matter in the water. This oxygen supply helps improve treatment efficiency and reduce pollutant concentrations in the wastewater.

[0003] When an air suspension fan for sewage treatment is in use, the speed of its internal pump is lower than the critical value at the initial startup or shutdown, and there is still a brief contact friction between the rotor and the bearing surface. Long-term frequent start and stop will accelerate the wear of the foil and shorten the life of the bearing. During the start and stop process, the mechanical system usually experiences some vibration and impact, especially in the process of gradual change in speed. The system pressure and flow do not match (such as sudden change in pipe network resistance or filter blockage), causing the airflow to separate from the impeller. The fan will vibrate and make noise violently under low flow and high pressure difference conditions, and may even cause shutdown, which will not only cause equipment overheating, but may even cause blade damage, reducing the overall operating efficiency of the system. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem of large friction between the rotor and the stator during the start-up and stop processes in the prior art, and to propose an air suspension fan for sewage treatment.

[0009] The sensing mechanism is arranged on the mounting pipe and can sense the wind force of the fan to judge the operating status of the pump;

[0010] Two sets of supporting mechanisms are arranged in the pump and cooperate with the sensing mechanism to provide friction protection for the pump during the speed reduction and speed increase stages according to the operating status of the pump, so as to reduce the friction consumption generated in the pump.

[0011] In the above-mentioned air suspension fan for sewage treatment, the upper end of the mounting pipe is fixedly connected to an air outlet pipe, and the air outlet pipe is fixedly passed through the upper surface of the box body.

[0012] In the above-mentioned air suspension fan for sewage treatment, the sensing mechanism includes a receiving groove opened in the mounting tube, a rotating hole is opened on the mounting tube, a rotating shaft is sealed and rotatably installed in the rotating hole, a damping bearing is installed between the rotating shaft and the rotating hole, and a swing blade is fixedly installed on one side of the rotating shaft located in the mounting tube, and the swing blade can be rotated into the receiving groove without blocking the pipe opening of the mounting tube.

[0015] In the above-mentioned air suspension fan for sewage treatment, a first belt transmission structure is installed between the circular shaft and one of the rotating rods, and a second belt transmission structure is installed between the two rotating rods.

[0016] In the above-mentioned air suspension blower for sewage treatment, two stators are fixedly arranged in the pump, and a rotor is rotatably installed between the two stators.

[0017] In the above-mentioned air suspension fan for sewage treatment, the supporting mechanism includes a thread arranged on a rotating rod, a fixed shell is fixedly installed in the pump machine, and the rotating rod seal rotates on the fixed shell, the thread length on the rotating rod is smaller than the horizontal length of the fixed shell and is located inside the fixed shell, and a blocking block is threadedly installed on the rotating rod.

[0018] In the above-mentioned air suspension fan for sewage treatment, the part of the rotating rod located outside the fixed shell is fixedly installed with a one-way bearing, the outside of the one-way bearing is fixedly installed with a rotating ring, the side of the rotating ring close to the fixed shell is fixedly installed with a positive pole magnet 1, the part of the rotating rod located inside the fixed shell is slidably installed with a slip ring, and the side of the slip ring close to the rotating ring is fixedly provided with a negative pole magnet and a positive pole magnet 2.

The system can issue an alarm in time to help maintenance personnel discover and solve the problem in advance to prevent the fault from expanding. While measuring the wind speed, the wind speed can be used to analyze the operating status of the pump, and the flexible support of the rotor can be adjusted during start and stop to reduce the friction between the stator and the rotor during start and stop. The rotor is supported synchronously according to its operating status. While supporting, the swing blades in the start and stop states are used to block the fan port to a certain extent, which can effectively suppress surge phenomenon, ensure the stable operation of the fan system, reduce vibration and noise, improve the operating efficiency of the fan and pump, reduce wear, reduce energy consumption and noise, and extend the service life of the equipment. The combination of the three helps to improve the working efficiency and economy of the entire sewage treatment system. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Reference Figure 1-Figure 7, an air suspension fan for sewage treatment, including a box body 1, a pump 4 is fixedly installed in the box body 1, two stators 16 are fixedly provided in the pump 4, a rotor 15 is rotatably installed between the two stators 16, a fan 3 is fixedly installed on the driving end of the pump 4, the outlet end of the fan 3 is fixedly connected with a mounting pipe 6, the upper end of the mounting pipe 6 is fixedly connected with an air outlet pipe 2, and the air outlet pipe 2 is fixedly passed through the upper surface of the box body 1 (the length design and layout of the air outlet pipe 2 usually need to be flexibly arranged to adapt to the requirements of space, interface and configuration. The air outlet pipe 2 needs to extend out of the box body 1 to deliver compressed air to specific components, especially in some parts that need adjustment), and also includes: a mounting cover 5, which is fixedly arranged on the outside of the fan 3, for correspondingly shielding the internal mounting structure, dustproof and beautiful.

[0038] It also includes multiple support plates, which are all fixedly arranged in the mounting cover 5, and a circular shaft is installed between the multiple support plates for common rotation; it also includes a sensing mechanism, which is arranged on the mounting tube 6 and can sense the wind force of the fan 3 to judge the operating status of the pump 4. The sensing mechanism includes a receiving groove 9 opened in the mounting tube 6, a rotating hole is opened on the mounting tube 6, and a rotating shaft 8 is sealed and rotatably installed in the rotating hole. A damping bearing is installed between the rotating shaft 8 and the rotating hole. A swing blade 7 is fixedly installed on one side of the rotating shaft 8 in the mounting tube 6, and the swing blade 7 can be rotated into the receiving groove 9 without blocking the pipe mouth of the mounting tube 6. A gear 11 is fixedly installed on the circular shaft, and a half gear ring 10 is fixedly provided on the outer side of the rotating shaft 8 of the mounting tube 6, and the half gear ring 10 is engaged with the gear 11 for use.

[0039] When the pump 4 is not working, the fan 3 is also not working (the power of the fan 3 is provided by the pump 4). The swing blade 7 is not affected by the wind at this time and is located in the installation pipe 6 to block the end of the installation pipe 6 (such as Figure 5As shown), the swing blade 7 blocks the outlet of the fan 3 to a certain extent, which can effectively suppress the surge phenomenon, ensure the stable operation of the fan 3 system, and reduce vibration and noise; when the pump 4 is turned on, the swing blade 7 is gradually rotated into the receiving groove 9 by the wind. When the swing blade 7 rotates into the receiving groove 9, it proves that the pump 4 and the fan 3 are in a normal and fast running state. Outside of this state (the other states belong to the process of starting the pump 4 to reach the normal and fast running state and the process of shutting down the pump 4 until it stops), during this process, the swing blade 7 will drive the rotating shaft 8 to rotate, and the rotation of the rotating shaft 8 drives the half gear ring 10 to rotate together, and this process will engage with the gear 11. When the pump 4 and the fan 3 are operating normally, the swing blade 7 is in the receiving groove 9, and the half gear ring 10 is no longer engaged with the gear 11. The gear 11 is meshed with each other, and this setting can prevent the slight shaking of the pendulum blade 7 from causing the gear 11 to shake unstably and affect the operation effect. At the same time, a cam (not shown in the figure) can be set at one end of the half gear ring 10, and a reminder switch button is set in the installation cover 5. When the pump 4 and the fan 3 are in normal operation, the cam at this time will be against the switch button. When there is a fault in the pump 4 and the fan 3, the wind force is not enough to make the half gear ring 10 rotate to the corresponding angle. At this time, the switch button is not started. When the outside personnel do not receive the information of this switch button, they can perform fault detection on the pump 4 and the fan 3 to ensure normal operation; at the same time, the diameter of the gear 11 is much smaller than the diameter of the rotating shaft 8, which meets the speed difference requirement (the figure is only for reference, and the specific setting is adjusted according to the required installation).

[0040] Reference Figure 6-Figure 14 , multiple fixed plates are fixedly installed in the mounting cover 5, and a rotating rod 14 is rotatably installed between the corresponding two fixed plates, and the two rotating rods 14 are sealed and rotated in sequence, pass through the mounting cover 5, the pump machine 4 and are located in the pump machine 4, and a belt transmission structure 12 is commonly installed between the circular shaft and one of the rotating rods 14, and a belt transmission structure 2 13 is commonly installed between the two rotating rods 14. The belt transmission structure 1 12 includes a pulley 1 respectively fixedly installed on the circular shaft and one of the rotating rods 14, and a conveyor belt 1 is provided between the two pulleys 1. The belt transmission structure 2 13 includes a pulley 2 respectively fixedly installed on the two rotating rods 14, and a conveyor belt 2 is provided between the two pulleys 2. The rotation of the circular shaft drives the corresponding rotating rod 14 to rotate through the belt transmission structure 12, and the rotation of the rotating rod 14 drives the other rotating rod 14 to rotate through the belt transmission structure 2 13.

[0041] Two sets of supporting mechanisms are arranged in the pump 4 and cooperate with the sensing mechanism. According to the operating state of the pump 4, the pump 4 is subjected to friction protection in the speed reduction and speed increase stages, so as to reduce the friction consumption generated in the pump 4. The supporting mechanism includes a thread arranged on the rotating rod 14. A fixed shell 17 is fixedly installed in the pump 4, and the rotating rod 14 is sealed and rotated on the fixed shell 17. The thread length on the rotating rod 14 is less than the horizontal length of the fixed shell 17 and is located in the fixed shell 17. A blocking block 27 is threadedly installed on the rotating rod 14. The part of the rotating rod 14 located outside the fixed shell 17 is fixedly installed with a one-way bearing. A swivel 21 is fixedly installed on the outside of the one-way bearing. A positive magnet 2 is fixedly installed on the side of the swivel 21 close to the fixed shell 17. 3. A slip ring 26 is slidably mounted on the portion of the rotating rod 14 located inside the fixed housing 17. A negative magnet 24 and a positive magnet 2 25 are fixedly mounted on the side of the slip ring 26 close to the rotating ring 21. A conduit 19 and a conduit 2 20 are fixedly connected to the fixed housing 17. The two pipe openings of the conduit 19 and the conduit 2 20 are symmetrically arranged with the end face of the rotor 15 as the center point. The two upper pipe openings of the conduit 19 are fixedly connected to a balancing ball 29. Pistons 22 are sealingly and slidably mounted in the two pipe openings of the conduit 2 20. Vertical rods 28 are fixedly mounted on the two pistons 22. Support rings 18 are fixedly mounted on the upper ends of the two vertical rods 28. The inner diameter of the support ring 18 is the same as the diameter of the balancing ball 29, which is used to support the balancing ball 29.

[0042] The two sets of support structures cooperate to support the rotor 15. When the pump 4 starts and stops, the friction between the rotor 15 and the stator 16 is large. To reduce the friction between the rotor 15 and the stator 16, when the pump 4 is just started, the gap between the rotor 15 and the stator 16 (for example, the gap between the existing internal structure: bearings, sealing rings or other components) is usually small. Since the speed gradually increases from zero, the mechanical friction at the time of startup is usually relatively large, especially between bearings, seals and other mechanical contact surfaces. At this time, the relative speed of the rotor 15 and the stator 16 changes dramatically, resulting in increased friction; when the pump 4 stops, the speed gradually drops to zero. During this process, the relative movement speed between the rotor 15 and the stator 16 gradually slows down, and the effect of friction becomes more obvious. During the stop process, the friction will gradually increase with the decrease in speed because the frequency of contact between the rotor 15 and the stator 16 increases. However, when the speed decreases, the effects of inertia and speed will also affect the contact situation. At the same time, abnormal rotation of the rotor 15 will cause surge (which can easily cause existing blades inside the fan 3 to break). The increase in friction will cause energy loss when the rotor 15 rotates, and the energy consumption is high. The air flow provided by the fan 3 requires high energy consumption, and the overall operating cost needs to be reduced.

[0043] When the pump 4 is started, the rotating rod 14 rotates so that the blocking block 27 moves to the right along the thread on the rotating rod 14 (refer to Figure 13 In the middle direction), at this time, the connecting points of the conduit 19, the conduit 20 and the fixed shell 17 are located on the same vertical line and are located on the right side of the blocking block 27 (as above). During the movement of the blocking block 27 to the right, the air in the fixed shell 17 will enter the conduit 19 and the conduit 20. At this time, the balancing ball 29 will gradually become larger under the filling of gas. At the same time, the piston 22 in the conduit 20 moves upward, driving the two support rings 18 to reach the position of the balancing ball 29, supporting the two balancing balls 29, ensuring that the rotor 15 can rotate smoothly. At the same time, the flexible support of the balancing ball 29 can reduce the wear of the rotor 15, and the effect is more significant when the pump machine 4 is frequently switched on and off.

[0044] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are common means well known to those skilled in the art.

[0045] The specific operation steps of the present invention are as follows:

[0046] When the pump 4 is turned on, the swing blade 7 is gradually rotated into the accommodating groove 9 by the wind. During this process, the swing blade 7 will drive the rotating shaft 8 to rotate, and the rotation of the rotating shaft 8 will drive the half ring gear 10 to rotate together. The half ring gear 10 will mesh with the gear 11 and rotate. When the pump 4 and the fan 3 are running to a normal state, the swing blade 7 is in the accommodating groove 9, and the half ring gear 10 is no longer meshed with the gear 11. The cam at one end of the half ring gear 10 will abut against the switch button. When there is a fault in the pump 4 and the fan 3, the wind force is not enough to make the half ring gear 10 rotate to the corresponding angle, and the switch button is in an unactivated state. When the outside personnel do not receive the information of the switch button, they can perform fault detection on the pump 4 and the fan 3 to ensure normal operation.

[0047] The rotation of the gear 11 drives the shaft to rotate, and the shaft rotates while the corresponding rotating rod 14 is driven to rotate through the belt transmission structure 12. The rotation of the rotating rod 14 drives another rotating rod 14 to rotate through the belt transmission structure 2 13. The rotation of the two rotating rods 14 causes the blocking block 27 to move to the right along the thread on the rotating rod 14 (refer to Figure 13In the middle direction), during the movement of the blocking block 27 to the right, the air in the fixed shell 17 will enter the conduit 1 19 and the conduit 2 20. At this time, the balancing ball 29 will gradually become larger under the filling of gas, and at the same time, the piston 22 in the conduit 20 will move up, driving the two support rings 18 to reach the position of the balancing ball 29, supporting the two balancing balls 29, ensuring that the rotor 15 can rotate smoothly and reducing the friction between the rotor 15 and the stator 16. At the same time, during this process, the blocking block 27 can seal the connection between the conduit 1 19, the conduit 20 and the fixed shell 17 to ensure the stability of the balancing ball 29 and the support ring 18; when the pump 4 runs to a stable and normal state, the blocking block 27 moves to the right side of the connection position between the conduit 1 19, the conduit 20 and the fixed shell 17, and the conduit 1 19 and the conduit 20 are connected to the fixed shell 17 again. At this time, the air pressure in the balancing ball 29 is not enough to support it to contact with the rotor 15, and the support ring 18 will also move down to prevent affecting the operation of the rotor 15 and the stator 16;

[0048] When the pump 4 stops working, the wind force on the swing blade 7 gradually decreases, and the swing blade 7 gradually returns to its original position under the action of gravity and the damping bearing. Figure 5 In the middle state, the pipe opening of the mounting pipe 6 is blocked. During this process, the swing blade 7 drives the shaft 8 to rotate in the opposite direction. At this time, the rotating rod 14 will also rotate in the opposite direction. The blocking block 27 will move to the left during this process (refer to Figure 13 ), at the same time, the rotating rod 14 drives the rotating ring 21 to rotate through the one-way bearing, and the rotating ring 21 drives the positive pole magnet 1 23 to rotate to the same position as the positive pole magnet 2 25. At this time, under the repulsive effect of the positive pole magnet 1 23 and the positive pole magnet 2 25, the slip ring 26 moves quickly to the right (with Figure 13 For example), the slip ring 26 and the blocking block 27 cooperate to quickly squeeze the gas between the two into the balance ball 29, ensuring that the air pressure in the balance ball 29 is sufficient to support the rotor 15, and then the blocking block 27 continues to move to the left until it moves to Figure 13 The initial state in (the pump 4 stops running at this time), the rotating ring 21 drives the positive pole magnet 1 23 back to the direction again, and the sliding ring 26 can be pushed by the blocking block 27 to get close to the rotating ring 21. At this time, the positive pole magnet 1 23 and the negative pole magnet 24 attract each other and return to the initial position ( Figure 13 The rotor 15 is protected from wear by this cycle, and the fan 3 can be operated smoothly and its operation stability can be improved.

[0049] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
