Description

Technical Field

[0001] This utility model relates to the field of aeration blower air volume adjustment equipment, and in particular to an air volume adjustment mechanism for an aeration blower. Background Technology

[0002] The airflow regulating mechanism of an aeration blower generally refers to a device or system used to control and regulate the output airflow of the aeration blower. Aeration blowers are widely used in wastewater treatment, aquaculture, and industrial waste gas treatment, mainly for conveying air into liquids or gases to achieve aeration, stirring, or mixing.

[0003] In situations requiring a wide range of airflow adjustment, the system may not be able to respond flexibly, resulting in insufficient or excessive airflow. It may be necessary to rely on other adjustment methods such as frequency converters or servo motors. However, these methods are more expensive and may experience a decrease in efficiency at low airflow, leading to insufficient or excessive airflow, airflow fluctuations or instability, increased system costs, limited airflow adjustment range, and an inability to flexibly respond to different operating conditions.

[0004] When the air outlet is directly exposed, the aeration range is limited to the vicinity of the equipment and cannot deliver air to the far end or deep areas of the tank. If the blower is located at one end without a pipe connection, there will be a significant difference in dissolved oxygen distribution between the far end and the near end, resulting in uneven distribution of microorganisms. For aeration tanks with greater depth, the rising path of the bubbles exposed at the air outlet is short, which will reduce the oxygen utilization rate, affect the treatment efficiency, and increase the frequency of sludge removal and the burden of operation and maintenance. Utility Model Content

[0005] The main purpose of this utility model is to provide an air volume adjustment mechanism for aeration blowers, which can effectively solve the problems of insufficient or excessive air volume, air volume fluctuation or instability, increased system cost, limited air volume adjustment range, inability to flexibly cope with different working conditions, uneven distribution of microorganisms, short rising path of exposed bubbles in aeration tanks with greater depth, reduced oxygen utilization, reduced treatment efficiency, increased sludge removal frequency and maintenance burden.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a flow rate regulating mechanism for an aeration blower, comprising a centrifugal blower, a support base fixedly connected to the bottom of the centrifugal blower, an inlet pipe fixedly connected to the input end of the centrifugal blower, an outlet pipe fixedly connected to the output end of the centrifugal blower, an outer frame fixedly connected to the inside of the right end of the outlet pipe, support plates fixedly connected to the front and rear side walls of the outer frame, a fixing ring fixedly connected to the right end of the outer frame, a first bearing fixedly connected to the inside of each of the two support plates, a first rotating rod rotatably connected to the inside of each of the two first bearings, a first baffle fixedly connected to the outer side of the middle of the first rotating rod, a first support rod fixedly connected to the outer side of the front end of the first bearing, a first connecting rod fixedly connected to the middle of the first support rod, and a first push rod fixedly connected to the inside of the right side of the first support rod.

[0007] Furthermore, a second bearing is fixedly connected to the interior of both the upper and lower sides of the two support plates, and a second rotating rod is rotatably connected to the interior of each pair of second bearings. A second baffle is fixedly connected to the exterior of each pair of second rotating rods, and the two second baffles are arranged on the upper and lower sides of the first baffle.

[0008] Furthermore, partitions are fixedly connected to the bottom of the right side wall and the top of the left side wall of the two second baffles, and the two partitions are set at the top of the right side wall and the bottom of the left side wall of the first baffle. Second support rods are fixedly connected to the outer front end of the two second rotating rods.

[0009] Furthermore, the right side walls of both second support rods are rotatably connected to second connecting rods, and the other ends of both second connecting rods are rotatably connected to the outside of the first connecting rod.

[0010] Furthermore, a left collar is fixedly connected to the right end of the fixed ring, and each of the left collars has an installation groove inside. The upper and lower side walls of the left collar are fixedly connected to first fixing plates, and the two first fixing plates are internally connected to a shell.

[0011] Furthermore, each of the outer shells is slidably connected to the left and right sides with a second push rod, and four springs are fixedly connected to the other side of each second push rod. The other end of each spring is fixedly connected to the inside of the outer shell, and two placement slots are opened inside the rear side of each outer shell.

[0012] Furthermore, a right collar is provided on the right side of the left collar, and an installation block is fixedly connected to the inside of the left side of the right collar. The outer sides of the six installation blocks are slidably connected to the inside of the six installation slots. The upper and lower side walls of the right collar are fixedly connected to second fixing plates, and the front side walls of the two second fixing plates are fixedly connected to locking blocks.

[0013] Furthermore, each of the card blocks is correspondingly set with each placement slot, the hole slot inside each of the card blocks is correspondingly set with the rear part of the second push rod, and an extension tube is fixedly connected inside the right collar.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. This utility model, through its outer frame, first bearing, first support rod, second bearing, second baffle, and second support rod, solves the problems of insufficient or excessive airflow, airflow fluctuations or instability, increased system costs, limited airflow adjustment range, and inability to flexibly cope with different working conditions. The first baffle on the first rotating rod also rotates under the action of the first push rod and the first support rod. Since the two second baffles are located on the upper and lower sides of the first baffle, and the second baffles cooperate with the first baffle through a partition, the area of ​​the ventilation channel formed between the three changes during the rotation of the first and second baffles. When the first and second baffles rotate to a certain angle, the ventilation duct area increases, and the airflow in the outlet duct increases; conversely, the ventilation duct area decreases, and the airflow in the outlet duct decreases, thereby effectively reducing airflow fluctuations, ensuring system stability, improving aeration effect, reducing energy consumption, and improving system efficiency.

[0016] 2. The system, consisting of a left collar, a first fixing plate, a second push rod, a placement slot, a right collar, a locking block, and an extension pipe, effectively addresses the issues of uneven microbial distribution, short upward paths for exposed air bubbles in deeper aeration tanks, reduced oxygen utilization, decreased treatment efficiency, increased sludge removal frequency, and increased maintenance burden. The second fixing plate moves the locking block closer to the placement slot on the rear of the casing. At this point, manually pulling the second push rod outward compresses the spring, causing the rear of the push rod to enter the slot inside the locking block. Simultaneously, the locking block embeds into the placement slot, securing the left and right collars together. This allows the extension pipe to be stably installed on the outlet pipe, effectively increasing the contact time between oxygen and water, improving oxygen utilization, reducing downtime for maintenance, and ensuring the continuity and stability of the wastewater treatment process.

[0032] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0033] like Figure 1 - Figure 4 The diagram shows an airflow regulating mechanism for an aeration blower, comprising a centrifugal blower 1. A support base 2 is fixedly connected to the bottom of the centrifugal blower 1, providing bottom support and securing it to the bank and water surface of the pool. An air inlet pipe 3 is fixedly connected to the input end of the centrifugal blower 1, and an air outlet pipe 4 is fixedly connected to the output end. Upon startup of the centrifugal blower 1, air enters the blower through the air inlet pipe 3, is pressurized by the blower, and is discharged from the air outlet pipe 4. An outer frame 5 is fixedly connected to the inside of the right end of the air outlet duct 4. Support plates 6 are fixedly connected to both the front and rear side walls of the outer frame 5. A fixing ring 7 is fixedly connected to the right end of the outer frame 5. First bearings 8 are fixedly connected inside the two support plates 6. First rotating rods 9 are rotatably connected inside the two first bearings 8. A first baffle 10 is fixedly connected to the outer side of the middle of the first rotating rod 9. A first support rod 11 is fixedly connected to the outer side of the front end of the first bearing 8. A first connecting rod 12 is fixedly connected to the middle of the first support rod 11. A first push rod 13 is fixedly connected to the inside of the right side of the first support rod 11. By pulling the first push rod 13, the first push rod 13 moves up and down, pushing the first support rod 11 connected to it. Since the first connecting rod 12 is fixedly connected to the middle of the first support rod 11, the movement of the first support rod 11 drives the first connecting rod 12 to move.

[0034] like Figure 1 - Figure 5 As shown, two second bearings 14 are fixedly connected to the interior of the upper and lower sides of the two support plates 6. A second rotating rod 15 is rotatably connected inside each pair of second bearings 14. A second baffle 16 is fixedly connected to the outer side of the two second rotating rods 15. The two second baffles 16 are located on the upper and lower sides of the first baffle 10. A partition 17 is fixedly connected to the bottom of the right side wall and the top of the left side wall of the two second baffles 16. The two partitions 17 are located at the top of the right side wall and the bottom of the left side wall of the first baffle 10. A second support rod 18 is fixedly connected to the outer side of the front end of each of the two second rotating rods 15. A second connecting rod 19 is rotatably connected to the right side wall of each of the two second support rods 18. The other end of each of the two second connecting rods 19 is rotatably connected to the outer side of the first connecting rod 12. The movement of the first connecting rod 12 will transmit power through the second connecting rod 19 connected to the outer side. The second connecting rod 19 is rotatably connected to the second support rod 18, and the second support rod 18 is fixed on the second rotating rod 15. Therefore, the movement of the second connecting rod 19 will drive the second support rod 18 to rotate around the second rotating rod 15, thereby causing the second baffle 16 fixed on the second rotating rod 15 to rotate.

[0035] Simultaneously, the first baffle 10 on the first rotating rod 9 will also rotate under the action of the first push rod 13 and the first support rod 11. Since the two second baffles 16 are located on the upper and lower sides of the first baffle 10, and the second baffles 16 and the first baffle 10 cooperate with each other through the partition 17, the area of ​​the ventilation channel formed between the three will change during the rotation of the first baffle 10 and the second baffle 16. When the first baffle 10 and the second baffle 16 rotate to a certain angle, the area of ​​the ventilation duct increases, and the air volume in the air outlet duct 4 increases; conversely, the area of ​​the ventilation duct decreases, and the air volume in the air outlet duct 4 decreases.

[0036] like Figure 1 - Figure 11 As shown, a left collar 20 is fixedly connected to the right end of the fixing ring 7. The left collar 20 has mounting grooves 21 inside, which connect to the device on the right side to fix the extension tube 31 to the left side of the outer frame 5. First fixing plates 22 are fixedly connected to the upper and lower side walls of the left collar 20. A housing 23 is penetrated through the interior of each of the two first fixing plates 22. Second push rods 24 are slidably connected to the left and right sides of each housing 23. Four springs 25 are fixedly connected to the other side of each second push rod 24. The other end of each spring 25 is fixedly connected to the interior of the housing 23. Two placement grooves 26 are opened inside the rear side of each housing 23. The first fixing plates 22 on the upper and lower sides of the left collar 20 fix the housing 23 externally, and the housing 23 connects to the device on the right side. This reinforces the fixing effect and prevents detachment when connecting the extension tube 31.

[0037] like Figure 1 - Figure 12 As shown, a right collar 27 is provided on the right side of the left collar 20. Mounting blocks 28 are fixedly connected to the interior of the left side of the right collar 27. The outer sides of the six mounting blocks 28 are slidably connected to the interior of the six mounting slots 21. Second fixing plates 29 are fixedly connected to the upper and lower side walls of the right collar 27. Locking blocks 30 are fixedly connected to the front side walls of the two second fixing plates 29. Each locking block 30 corresponds to each placement slot 26. The internal holes of each locking block 30 correspond to the rear of the second push rod 24. The right collar 27... An extension tube 31 is fixedly connected inside the 7. When the extension tube 31 needs to be connected, first align the mounting block 28 in the mounting groove inside the left side of the right collar 27 with the inlet and outlet of the mounting groove 21 inside the right side of the left collar 20, and push the right collar 27 close to the left collar 20. When it is close, rotate the right collar 27 forward so that the mounting block 28 slides from the right side of the mounting groove 21 into the left side of the mounting groove 21. At this time, the right collar 27 and the left collar 20 can achieve the effect of initial fixation.

[0038] Then, when the right collar 27 rotates, the second fixing plates 29 on both the upper and lower sides of the right collar 27 will rotate synchronously. After rotation, the second fixing plates 29 will fit against the first fixing plate 22. At this time, the locking block 30 on the left side of the second fixing plate 29 will enter the interior of the placement groove 26. After entering the interior of the placement groove 26, the left side wall of the locking block 30 will contact the rear part of the second push rod 24 and push the second push rod 24 to slide inside the outer shell 23 to compress the spring 25. When the locking block 30 is fully inserted into the interior of the placement groove 26, the spring 25 will release the pressure and drive the second push rod 24 to rebound, so that the rear part of the second push rod 24 is inserted into the interior of the locking block 30, thus fixing the locking block 30 and the right collar 27 on the right side of the left collar 20.

[0039] It should be noted that this utility model is an air volume regulating mechanism for an aeration blower. First, the centrifugal blower 1 is connected to an external power supply and control terminal to supply power and control the device.

[0040] When the centrifugal blower 1 is running, air enters the blower through the inlet pipe 3, is pressurized by the blower, and is discharged from the outlet pipe 4. The airflow in the outlet pipe 4 is adjusted by a linkage structure within the outer frame 5. When airflow needs to be adjusted, the first push rod 13 is pulled, causing it to move up and down, which in turn pushes the first support rod 11 connected to it. Since the first support rod 11 is fixedly connected to the first connecting rod 12 in the middle, the movement of the first support rod 11 drives the first connecting rod 12 to move.

[0041] The movement of the first connecting rod 12 transmits power through the rotatably connected second connecting rod 19. The second connecting rod 19 is rotatably connected to the second support rod 18, and the second support rod 18 is fixed on the second rotating rod 15. Therefore, the movement of the second connecting rod 19 will cause the second support rod 18 to rotate around the second rotating rod 15, thereby causing the second baffle 16 fixed on the second rotating rod 15 to rotate.

[0042] Simultaneously, the first baffle 10 on the first rotating rod 9 will also rotate under the action of the first push rod 13 and the first support rod 11. Since the two second baffles 16 are located on the upper and lower sides of the first baffle 10, and the second baffles 16 cooperate with the first baffle 10 through the partition 17, the area of ​​the ventilation channel formed between the three will change during the rotation of the first baffle 10 and the second baffle 16. When the first baffle 10 and the second baffle 16 rotate to a certain angle, the ventilation channel area increases, and the air volume in the outlet duct 4 increases; conversely, the ventilation duct area decreases, and the air volume in the outlet duct 4 decreases.

[0043] When it is necessary to connect the extension tube 31, align the mounting block 28 of the right collar 27 with the mounting groove 21 of the left collar 20 and insert it, pushing the right collar 27 closer to the left collar 20. As the right collar 27 approaches, the second fixing plate 29 on it causes the locking block 30 to gradually approach the placement groove 26 on the rear side of the outer casing 23. At this time, manually pull the second push rod 24 outward to compress the spring 25, so that the rear part of the second push rod 24 enters the internal hole groove of the locking block 30, and the locking block 30 is embedded in the placement groove 26, realizing a firm connection between the left collar 20 and the right collar 27, thereby stably installing the extension tube 31 on the air outlet duct 4.

[0044] To disassemble the extension tube 31, simply push the second push rod 24 inward. Under the elastic force of the spring 25, the second push rod 24 will disengage from the slot of the locking block 30, releasing the lock. This will allow the right collar 27 to separate from the left collar 20. Then, rotate the right collar 27 so that the mounting block 28 inside the left side of the right collar 27 slides from the left side of the mounting groove 21 inside the left collar 20 into the right side, allowing the extension tube 31 to be disassembled.

[0045] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
