Description

Technical Field

[0001] The present invention relates to the technical field of air suspension blowers, and particularly to an air suspension blower for sewage treatment. Background Art

[0002] An air suspension blower for sewage treatment (also known as an air flotation blower or an air suspension compressor) is mainly used to provide gas (such as air or oxygen) during the sewage treatment process. In the biological treatment process, especially in the activated sludge process, the air suspension blower supplies oxygen to the sewage to maintain the vital activities of aerobic microorganisms and promote their decomposition of organic substances in the water. This oxygen supply helps to improve the treatment efficiency and reduce the pollutant concentration in the sewage.

[0003] When the air suspension blower for sewage treatment is in use, during the initial startup or shutdown of its internal pump, the rotational speed is lower than the critical value, and there is still a short-term contact friction between the rotor and the bearing surface. Frequent startups and shutdowns over a long period will accelerate the wear of the foil and shorten the bearing life. During the startup and shutdown processes, the mechanical system usually experiences some vibrations and impacts. Especially during the process of gradually changing the rotational speed, the system pressure and flow rate do not match (such as a sudden change in the pipeline network resistance or a filter blockage), resulting in the air flow detaching from the impeller. The blower will experience severe vibrations and noises under low-flow and high-pressure difference conditions, and even lead to shutdown. This will not only cause the equipment to overheat, but may even cause the blades to be damaged, 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 the large frictional force between the rotor and the stator during the startup and shutdown processes in the prior art, and to propose an air suspension blower for sewage treatment.

[0015] In the above-mentioned air suspension blower for sewage treatment, a belt drive structure one is commonly installed between the round shaft and one of the rotating rods, and a belt drive structure two is commonly installed between the two rotating rods.

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

Detailed implementation manners

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] Refer to Figures 1 - 7, An air suspension blower for sewage treatment, including a box body 1. A pump 4 is fixedly installed inside the box body 1. Two stators 16 are fixedly arranged inside the pump 4. A rotor 15 is rotatably installed between the two stators 16. A blower 3 is fixedly installed at the driving end of the pump 4. The outlet end of the blower 3 is fixedly communicated with an installation pipe 6. The upper port of the installation pipe 6 is fixedly communicated with an air outlet pipe 2, and the air outlet pipe 2 fixedly penetrates 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 meet the requirements of space, interfaces and configurations. The air outlet pipe 2 needs to extend out of the box body 1 to deliver compressed air to specific components, especially at some parts that need to be adjusted). It also includes: an installation cover 5, which is fixedly arranged outside the blower 3 and is used to correspondingly shield the internal installation structure, preventing dust and being aesthetically pleasing.

[0038] It also includes multiple support plates, and multiple support plates are all fixedly arranged inside the installation cover 5. A round shaft is rotatably installed among the multiple support plates. It also includes an induction mechanism, which is arranged on the installation pipe 6 and can sense according to the wind force of the blower 3 to judge the operating state of the pump 4. The induction mechanism includes a receiving groove 9 opened inside the installation pipe 6. A rotating hole is opened on the installation pipe 6. A rotating shaft 8 is hermetically 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 located inside the installation pipe 6, and the swing blade 7 can rotate into the receiving groove 9 without blocking the pipe orifice of the installation pipe 6. A gear 11 is fixedly installed on the round shaft. A semi-toothed ring 10 is fixedly arranged on the outside of the rotating shaft 8 located outside the installation pipe 6, and the semi-toothed ring 10 meshes with the gear 11.

[0039] When the pump 4 is not working, at this time the blower 3 is also not working (the power of the blower 3 is provided by the pump 4). The swing blade 7 is not affected by the wind force at this time and is located inside the installation pipe 6 to block the port of the installation pipe 6 (such as Figure 5As shown, the swinging 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 starts to work, the swinging blade 7 is gradually rotated into the receiving groove 9 by the wind force. When the swinging 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 this state (the remaining 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 swinging blade 7 will drive the rotating shaft 8 to rotate, and the rotation of the rotating shaft 8 drives the semi-toothed ring 10 to rotate together. This process will mesh with the gear 11. When the pump 4 and the fan 3 are running normally, the swinging blade 7 is in the receiving groove 9 at this time, and the semi-toothed ring 10 no longer meshes with the gear 11. This setting can prevent the slight shaking of the swinging blade 7 from driving the unstable shaking of the gear 11 and affecting the operation effect. At the same time, a cam (not shown in the figure) can be provided at one end of the semi-toothed ring 10, and a reminder switch button is provided in the installation cover 5. When the pump 4 and the fan 3 are in a normal running state, the cam at this time will abut against the switch button. When there is a fault in the pump 4 or the fan 3, the wind force is not enough to rotate the semi-toothed ring 10 to the corresponding angle at this time, and the switch button is in an unactivated state. When external personnel do not receive the information of this switch button, they can detect the faults of the pump 4 and the fan 3 to ensure the normal progress of the work. At the same time, the diameter of the gear 11 is much smaller than the diameter of the rotating shaft 8 to meet the rotational speed difference requirement (only for illustration in the figure, and the specific setting situation shall be adjusted according to the required installation).

[0040] Referring to Figures 6 - 14 , a plurality of fixing plates are fixedly installed in the installation cover 5. A rotating rod 14 is rotatably installed between two corresponding fixing plates, and both rotating rods 14 are sequentially and sealingly rotatably penetrated through the installation cover 5 and the pump 4 and are located inside the pump 4. A belt drive structure one 12 is jointly installed between the round shaft and one of the rotating rods 14, and a belt drive structure two 13 is jointly installed between the two rotating rods 14. The belt drive structure one 12 includes belt pulleys one respectively fixedly installed on the round shaft and one of the rotating rods 14, and a conveyor belt one is jointly rotatably sleeved between the two belt pulleys one. The belt drive structure two 13 includes belt pulleys two respectively fixedly installed on the two rotating rods 14, and a conveyor belt two is jointly rotatably sleeved between the two belt pulleys two. The rotation of the round shaft drives the corresponding rotating rod 14 to rotate through the belt drive structure one 12, and the rotation of this rotating rod 14 drives the other rotating rod 14 to rotate through the belt drive structure two 13.

[0041] Two sets of support mechanisms are arranged inside the pump 4 and cooperate with the induction mechanism to protect the pump 4 from friction during the deceleration and acceleration stages of the pump 4 according to the operating state of the pump 4, and are used to reduce the frictional consumption generated inside the pump 4. The support mechanism includes threads provided on the rotating rod 14. A fixed housing 17 is fixedly installed inside the pump 4, and the rotating rod 14 rotates in a sealed manner on the fixed housing 17. The length of the thread on the rotating rod 14 is less than the horizontal length of the fixed housing 17 and is located inside the fixed housing 17. A shielding block 27 is threadedly installed on the rotating rod 14. A one-way bearing is fixedly installed on the portion of the rotating rod 14 outside the fixed housing 17. A rotating ring 21 is fixedly installed on the outside of the one-way bearing. A first positive magnet 23 is fixedly installed on the side of the rotating ring 21 close to the fixed housing 17. A sliding ring 26 is slidably installed on the portion of the rotating rod 14 inside the fixed housing 17. A negative magnet 24 and a second positive magnet 25 are fixedly arranged on the side of the sliding ring 26 close to the rotating ring 21. A first conduit 19 and a second conduit 20 are fixedly communicated with the fixed housing 17. The two pipe orifices of the first conduit 19 and the second conduit 20 are symmetrically arranged with the end face of the rotor 15 as the center point. Balance balls 29 are fixedly communicated with the two upper pipe orifices of the first conduit 19. Pistons 22 are hermetically and slidably arranged inside the two pipe orifices of the second conduit 20. Vertical rods 28 are fixedly installed on both pistons 22. Support rings 18 are fixedly installed at the upper ends of the two vertical rods 28, and the inner diameter of the support ring 18 is the same as the diameter of the balance ball 29 to support the balance ball 29.

[0042] Two sets of support structures cooperate to support the rotor 15. When the pump 4 starts and stops, the frictional force between the rotor 15 and the stator 16 is relatively large. Reducing the frictional force between the rotor 15 and the stator 16. When the pump 4 starts for the first time, the gap between the rotor 15 and the stator 16 (such as the existing internal structure: the gap of bearings, sealing rings or other components) is usually small. Since the rotational speed gradually increases from zero, the mechanical friction at the start is usually relatively large, especially between the bearings, seals and other mechanical contact surfaces. At this time, the relative speed change between the rotor 15 and the stator 16 is relatively drastic, resulting in an increase in the frictional force; when the pump 4 stops, the rotational speed gradually decreases to zero. During this process, the relative movement speed between the rotor 15 and the stator 16 gradually slows down, and the effect of the frictional force becomes more obvious. During the stop process, the frictional force will gradually increase as the rotational speed decreases because the contact frequency between the rotor 15 and the stator 16 increases. However, when the rotational speed decreases, the inertia and the effect of the rotational speed will also affect the contact situation. At the same time, abnormal rotation of the rotor 15 will cause a surging phenomenon (which is likely to cause breakage of the existing blades inside the fan 3). The increase in the frictional force will lead to energy loss during the rotation of the rotor 15, the energy consumption is relatively high, and the air flow provided by the fan 3 requires a relatively high energy consumption, and the overall operating cost needs to be reduced.

[0043] When the pump 4 starts, the rotation of the rotating rod 14 at this time causes the shielding block 27 to move to the right along the thread on the rotating rod 14 (refer toFigure 13 In the middle direction), at this time, the connection points of the first conduit 19 and the second conduit 20 with the fixed housing 17 are on the same vertical line and are located on the right side of the shielding block 27 (as above). When the shielding block 27 moves to the right, the air in the fixed housing 17 will enter the first conduit 19 and the second conduit 20. At this time, the balance balls 29 will gradually expand under the filling of the gas. At the same time, the piston 22 in the second conduit 20 moves upward, driving the two support rings 18 to reach the position of the balance balls 29 to support the two balance balls 29, ensuring that the rotor 15 can rotate smoothly. At the same time, the flexible support of the balance balls 29 can reduce the wear of the rotor 15, and the effect is more significant when frequently starting and stopping the pump 4.

[0044] Further explanation, the above fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or integrally formed setting, 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 starts to work, at this time, the swing blade 7 gradually rotates into the receiving groove 9 under the action of the wind force. During this process, the swing blade 7 drives the rotating shaft 8 to rotate. The rotation of the rotating shaft 8 drives the semi-gear ring 10 to rotate together. The semi-gear ring 10 meshes and rotates with the gear 11 for a while. When the pump 4 and the fan 3 run to the normal state, at this time, the swing blade 7 is in the receiving groove 9, and the semi-gear ring 10 no longer meshes with the gear 11. The cam at one end of the semi-gear ring 10 abuts against the switch button. When there is a fault in the pump 4 or the fan 3, at this time, the wind force is not enough to make the semi-gear ring 10 rotate to the corresponding angle, and the switch button is in the unactivated state. When external personnel do not receive the information of this switch button, they can detect the faults of the pump 4 and the fan 3 to ensure the normal operation;

[0047] The rotation of the gear 11 drives the round shaft to rotate. While the round shaft rotates, it drives the corresponding rotating rod 14 to rotate through the first belt drive structure 12. The rotation of the rotating rod 14 drives another rotating rod 14 to rotate through the second belt drive structure 13. The rotation of the two rotating rods 14 makes the shielding block 27 move to the right along the thread on the rotating rod 14 (refer to Figure 13In the middle direction), when the shielding block 27 moves to the right, the air in the fixed housing 17 will enter the first conduit 19 and the second conduit 20. At this time, the balance balls 29 will gradually expand under the filling of the gas. At the same time, the piston 22 in the second conduit 20 moves upward, driving the two support rings 18 to the position of the balance balls 29 to support the two balance balls 29, ensuring that the rotor 15 can rotate smoothly, reducing the friction between the rotor 15 and the stator 16. At the same time, during this process, the shielding block 27 can seal the connection between the first conduit 19, the second conduit 20 and the fixed housing 17, ensuring the stability of the balance balls 29 and the support rings 18; when the pump 4 operates in a stable and normal state, at this time, the shielding block 27 moves to the right of the connection position of the first conduit 19, the second conduit 20 and the fixed housing 17, and the first conduit 19 and the second conduit 20 are again in communication with the fixed housing 17. At this time, the air pressure in the balance balls 29 is not sufficient to support them to contact the rotor 15, and the support rings 18 will also move downward to prevent affecting the operation of the rotor 15 and the stator 16;

[0048] When the pump 4 stops working, the wind force received by the swing blades 7 gradually decreases. At this time, the swing blades 7 gradually return to the Figure 5 middle state under the action of gravity and the damping bearing, covering the nozzle of the installation pipe 6. During this process, the swing blades 7 will drive the rotating shaft 8 to rotate in the reverse direction. At this time, the rotating rod 14 will also rotate in the reverse direction. The shielding 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 first positive magnet 23 to rotate to the same position as the second positive magnet 25. At this time, under the repulsive action of the first positive magnet 23 and the second positive magnet 25, the slip ring 26 moves quickly to the right (taking Figure 13 as an example). The slip ring 26 and the shielding block 27 cooperate to quickly squeeze the gas between them into the balance balls 29, ensuring that the air pressure in the balance balls 29 is sufficient to support the rotor 15. Then the shielding block 27 continues to move to the left until it moves to the Figure 13 initial state in (at this time the pump 4 stops running), at the same time, the rotating ring 21 drives the first positive magnet 23 back to this direction again. Under the push of the shielding block 27, the slip ring 26 can approach the rotating ring 21. At this time, under the attractive action of the first positive magnet 23 and the negative magnet 24, it returns to the initial position ( Figure 13 the position in), and so on in a cycle, completing the wear protection of the rotor 15, and at the same time ensuring the stable operation of the fan 3 and improving its operation stability.

[0049] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
