Description

Technical Field

[0001] This utility model relates to the field of aerator technology, and in particular to a retractable impeller aerator. Background Technology

[0002] With industrial development and urbanization, environmental problems, especially water pollution, have become increasingly prominent. Therefore, intensifying water pollution control efforts is an urgent task. Wastewater treatment largely employs biological processes, with a key technology being the aeration of the biological treatment tank. Furthermore, due to limited land resources, biological treatment tanks are increasingly being developed into deep trench types. This necessitates that aerators simultaneously aerate and agitate the sludge to prevent sedimentation at the bottom of the trench. Vertical inverted umbrella-type surface aerators are widely used in the industry due to their advantages of not clogging or becoming dirty during operation and their strong oxygenation capacity.

[0003] In existing retractable impeller aerator technology, the impeller is easily corroded by harmful substances in sewage during long-term use. However, the existing impeller is fixed, which means that the impeller cannot be disassembled individually when it is corroded, and the whole unit needs to be replaced, which greatly increases the production cost and has limited practicality. Therefore, we propose a retractable impeller aerator to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a retractable impeller aerator to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A retractable impeller aerator includes: a motor; a gearbox fixedly mounted at the bottom of the motor; a rotating rod rotatably mounted inside the gearbox; a limiting cylinder fixedly mounted at the bottom of the rotating rod; a telescopic shaft slidably connected inside the limiting cylinder; a connecting cylinder movably inserted into the outer side of the telescopic shaft; an impeller body fixedly mounted at the bottom of the connecting cylinder; a protective cylinder fixedly mounted on the outer side of the connecting cylinder; two rectangular blocks fixedly mounted inside the protective cylinder; each of the two rectangular blocks has an inclined groove inside; a pushing block slidably connected within each of the two inclined grooves; an inclined block movably abutting one side of each of the two pushing blocks; an insert rod fixedly mounted on the inner side of each of the two inclined blocks; a fixing ring fixedly mounted on the outer side of each of the two insert rods; a first-order return spring fixedly connected to one side of each of the two fixing rings; one end of each first-order return spring fixedly connected to the outer side of the corresponding rectangular block; the two first-order return springs sleeved on the outer side of the corresponding insert rods; and the sides of the two insert rods that are close to each other movably inserted into the inside of the telescopic shaft.

[0012] In this utility model, a retractable impeller aerator is described. By pulling the pull plate, the sliding ring and two connecting rods begin to slide along the connecting cylinder, thereby moving the connecting plate and further moving the pushing block. This causes the pushing block to stop abutting the inclined block, allowing the inclined block to move along the rectangular block, which in turn moves the insert rod. This causes the insert rod to disengage from the inside of the telescopic shaft, thus freeing it from fixing the connecting cylinder and the telescopic shaft. This facilitates the maintenance and replacement of the connecting cylinder and the impeller body without requiring a complete replacement, significantly reducing production costs and broadening its applicability.

[0013] In this utility model, a retractable impeller aerator is described. By activating an electric push rod, the telescopic shaft and T-shaped slider are moved vertically along the T-shaped slide groove. This further drives the connecting cylinder and impeller body to move vertically along the T-shaped slide groove. As a result, the user can adjust the distance of the impeller body extension according to the specific water level, ensuring that the impeller body can achieve the best contact state with the water surface, which greatly improves work efficiency.

[0014] This utility model has a reasonable structural design. Through the cooperation between the sliding ring, pull plate, connecting rod, connecting plate, push block, inclined groove and insert rod, the insert rod no longer needs to fix the connecting cylinder and telescopic shaft. This makes it convenient to repair and replace the connecting cylinder and impeller body without replacing the whole, which greatly reduces the production cost and has wider applicability.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

Each of the two inclined slots 19 has a sliding push block 20 connected to it. One side of each of the two push blocks 20 is movably abutting against an inclined block 21. The inner side of each of the two inclined blocks 21 is fixedly installed with a plug rod 22. The outer side of each of the two plug rods 22 is fixedly installed with a fixing ring 23. One side of each of the two fixing rings 23 is fixedly connected with a first return spring 24. One end of each of the two first return springs 24 is fixedly connected to the outer side of the corresponding rectangular block 18. The two first return springs 24 are sleeved on the outer side of the corresponding plug rod 22. The side of the two plug rods 22 that are close to each other is movably inserted into the inside of the telescopic shaft 12.

[0022] In this embodiment, a rotating shaft 3 is fixedly connected to the output end of the motor 1. The outer side of the rotating shaft 3 is rotatably mounted inside the gearbox 2. A first worm segment 4 is fixedly mounted on the outer side of the rotating shaft 3. A first worm wheel 5 meshes with the outer side of the first worm segment 4. A rotating shaft 6 is fixedly mounted inside the first worm wheel 5. The outer side of the rotating shaft 6 is rotatably mounted inside the gearbox 2. A second worm segment 7 is fixedly mounted on the outer side of the rotating shaft 6. A second worm wheel 8 meshes with the outer side of the second worm segment 7. The inner side of the second worm wheel 8 is fixedly mounted on the outer side of the rotating rod 9, which facilitates driving the rotating rod 9 to rotate, and further drives the impeller body 16 to rotate.

[0023] In this embodiment, an electric push rod 11 is fixedly installed on the inner side of the top wall of the limiting cylinder 10. The output end of the electric push rod 11 is fixedly connected to the top of the telescopic shaft 12. Two T-shaped sliders 13 are fixedly installed on the outer side of the telescopic shaft 12. T-shaped grooves 14 are opened on both sides of the inner side of the limiting cylinder 10. The outer sides of the two T-shaped sliders 13 are slidably connected in the corresponding T-shaped grooves 14, which makes the telescopic shaft 12 more stable when it moves.

[0024] In this embodiment, a connecting plate 25 is fixedly installed on the top of each of the two pushing blocks 20. Two guide posts 26 are fixedly installed on the top of each of the two connecting plates 25. The top inner side of the top of the protective cylinder 17 is fixedly installed on the top of each of the four guide posts 26. A second return spring 27 is sleeved on the outer side of each of the four guide posts 26. The top of each of the four second return springs 27 is fixedly connected to the top inner side of the protective cylinder 17. The bottom of each of the four second return springs 27 is fixedly installed on the top of the corresponding rectangular block 18. A connecting rod 28 is fixedly installed on the top of each of the two connecting plates 25. Two first sealing gaskets 31 are fixedly installed on the top of the protective cylinder 17. The outer side of each of the two connecting rods 28 moves against the inside of the corresponding second sealing gasket 32. A pull plate 29 is fixedly installed on the top of each of the two connecting rods 28. The same sliding ring 30 is fixedly installed on the inner side of each of the two pull plates 29. The sliding ring 30 is slidably connected to the outer side of the connecting cylinder 15, so as to facilitate the movement of the connecting rod 28 by the pull plate 29, and further drive the insertion rod 22 to start moving.

[0025] In this embodiment, a second sealing gasket 32 ​​is fixedly installed at the bottom of the limiting cylinder 10, and the outer side of the telescopic shaft 12 moves against the inside of the second sealing gasket 32. Multiple rotating plates 34 are fixedly installed at the top of the limiting cylinder 10, and a circular groove 33 is opened at the bottom of the reduction gearbox 2. The tops of the multiple rotating plates 34 are rotatably installed in the circular groove 33, making the limiting cylinder 10 more stable when rotating.

[0026] In this embodiment, during use, the electric push rod 11 drives the telescopic shaft 12 and the T-shaped slider 13 to move vertically along the T-shaped groove 14, further driving the connecting cylinder 15 and the impeller body 16 to move vertically along the T-shaped groove 14. This allows the user to adjust the extension distance of the impeller body 16 according to the specific water level, ensuring optimal contact between the impeller body 16 and the water surface, greatly improving work efficiency. Then, the motor 1 is started, causing the rotating shaft 3 to rotate, which in turn drives the first worm segment 4 to rotate, thereby driving the first worm wheel 5 meshing with the first worm segment 4 to rotate, which in turn drives the rotating shaft 6 to rotate, thereby driving the second worm segment 7 to rotate, and subsequently driving the second worm wheel 8 meshing with the second worm segment 7 to rotate. The rotating rod 9 is driven to rotate, which in turn drives the impeller body 16 to rotate. When the impeller body 16 needs maintenance or replacement, the sliding ring 30 and the two connecting rods 28 are moved along the connecting cylinder 15 by pulling the pull plate 29. This causes the connecting plate 25 to move, which in turn causes the pushing block 20 to move. As a result, the pushing block 20 no longer abuts against the inclined block 21, and the inclined block 21 moves along the rectangular block 18. This causes the insertion rod 22 to move, disengaging it from the telescopic shaft 12. Thus, the insertion rod 22 no longer fixes the connecting cylinder 15 and the telescopic shaft 12, making it easier to maintain and replace the connecting cylinder 15 and the impeller body 16 without replacing the entire unit. This greatly reduces production costs and broadens its applicability.
