Description

Technical Field

[0001] The present application relates to the technical field of aerators, and more specifically, to a liftable aerator. Background Art

[0002] Sewage treatment methods can be divided into three types: physical treatment, chemical treatment and biological treatment. Biological treatment is an economical, effective and pollution-free sewage treatment method currently widely used in the world. Its principle is to use the metabolic function of microorganisms to decompose and oxidize dissolved organic substances in sewage into stable inorganic substances, so that sewage can be purified.

[0003] The aeration system disperses the air delivered by the fan into the water body through the aerator, which not only provides the dissolved oxygen required for the metabolism of microorganisms, but also has a stirring and mixing effect, so that the microorganisms are always in a suspended state in the water body and can fully contact with the water, providing favorable biochemical reaction conditions for the microorganisms to degrade organic matter.

[0004] In the related art, the aerator needs to be maintained after being used for a period of time or when a fault occurs. In order to facilitate the subsequent maintenance of the aerator, for example, the patent with the prior art publication number CN214192745U provides a liftable tubular microporous aerator. The device is provided with a second connecting block, a support rod, a threaded rod and a slider. When the aerator body at the bottom of the inner cavity of the box needs to be cleaned or maintained, the servo motor is turned on by an external controller, and the servo motor drives the rotating rod to rotate, and the rotating rod drives the threaded rod to rotate. The threaded rod drives the slider to move upward in the inner cavity of the slide groove, and the slider drives the first connecting block to move upward. The first connecting block pulls the lifting rope upward through the sliding hole, and the lifting rope drives the third connecting blocks on both sides to move upward at the same time through the guide wheel. The third connecting block drives the gas main pipe to be lifted upward, and the gas main pipe drives the aerator body to rise, thereby achieving the purpose of lifting, and solving the problem that the existing microporous aerator does not have the lifting function, which makes it very troublesome for people to maintain it in the later stage.

[0005] Although the above-mentioned existing technical solution can achieve the effect of lifting the aerator upward by driving the lifting rope to be retracted and released by a motor, the stability is poor during the process of lifting the aerator by the lifting rope, and it is easy to swing and collide with the inner wall of the box. In addition, it will shake when lifted to the top for maintenance work, affecting the safety of the maintenance work.

[0006] In view of this, we propose a liftable aerator. Summary of the invention

[0056] In order to make the technical solutions and advantages in the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all the embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0057] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5The embodiment of the present application discloses a liftable aerator, including an aeration assembly 1 arranged at the bottom of an aeration well 100, the aeration assembly 1 includes a wedge block A11 fixedly arranged on the outside and a vertical rod 12 slidably arranged on the outside, the vertical rod 12 is fixed inside the aeration well 100, and a lifting assembly 2 is symmetrically installed on the top of the aeration well 100 through a well top platform 101, the lifting assembly 2 includes a pull rope 21 for pulling the aeration assembly 1 to move inside the aeration well 100 along the vertical rod 12, and a clamping assembly 3 is fixedly arranged at the bottom of the well top platform 101 just above the wedge block A11, the clamping assembly 3 includes a wedge block B31 that is mutually engaged with the wedge block A11, and the lifting assembly 2 automatically releases the engagement of the wedge block B31 with the wedge block A11 when driving the aeration assembly 1 to descend.

[0058] In a specific implementation, the aeration assembly 1 is lifted upward by tightening the pull rope 21, so that the aeration assembly 1 rises vertically along the vertical rod 12, thereby ensuring stability during the lifting process. When the aeration assembly 1 rises to a certain height, the outer wedge block A11 corresponds to the wedge block B31 to form an engagement, so that the wedge block B31 supports the wedge block A11 to ensure stability when the aeration assembly 1 is lifted to the top. When the maintenance work of the aeration assembly 1 is completed, the pull rope 21 is loosened by reverse operation of the lifting assembly 2 to lower the aeration assembly 1 into the aeration well 100. At this time, the lifting assembly 2 first drives the wedge block B31 to automatically release the engagement with the wedge block A11, and gradually relaxes the pull rope 21. When the wedge block B31 is separated from the bottom of the wedge block A11, the aeration assembly 1 moves downward to the bottom of the wedge block B31 by its own gravity, so that the aeration assembly 1 can be put back into the aeration well 100 after maintenance.

[0059] On the basis of the above scheme, in order to realize the aeration function of the aeration component 1, refer to Figure 1 and Figure 2 The embodiment of the present application provides a specific implementation of an aeration assembly. The aeration assembly 1 also includes two lifting pipes 13, which are respectively fixed at the ends of two pull ropes 21. The lifting pipes 13 are slidably arranged on the outside of the vertical rod 12. A plurality of interconnected connecting pipes 14 are evenly fixed between the lifting pipes 13. A plurality of aeration pipes 15 are fixedly arranged on the outside of each connecting pipe 14, and a rubber hose 16 is fixedly arranged on the top of one connecting pipe 14. An air inlet pipe 17 is fixedly arranged on the other end of the rubber hose 16. The air inlet pipe 17 is fixedly arranged on the top of the aeration well 100.

[0060] In a specific implementation, when the aeration assembly 1 is located inside the aeration well 100, air is input into the rubber hose 16 through the air inlet pipe 17, the air flows to the plurality of aeration pipes 15 through the connecting pipe 14, and is input into the aeration well 100 through the aeration pipes 15 for aeration work; when performing maintenance lifting, the lifting pipe 13 is driven to move upward by the pull rope 21, so that the lifting pipe 13 slides along the vertical rod 12, to prevent the lifting pipe 13 from driving the aeration pipe 15 to swing inside the aeration well 100.

[0061] On the basis of the above scheme, in order to realize the engagement function of the wedge block B31 and the wedge block A11, refer to Figure 2 , Figure 3 and Figure 5 A roller 110 is rotatably arranged inside the wedge block A11, and the roller 110 is located on the inclined side of the wedge block A11. The wedge block A11 is fixed to the outside of the lifting pipe 13 through a limit block 18, and a limit groove 19 is provided inside the limit block 18.

[0062] In a specific implementation, when the lifting tube 13 is raised or lowered, the limit block 18 is driven to move outside the vertical rod 12, and the limit block 18 drives the wedge block A11 to approach the bottom of the wedge block B31. When the wedge block A11 contacts the wedge block B31, the outer roller 110 forms an extrusion thrust on the wedge block B31 to prevent the wedge block A11 from being corroded due to being underwater for a long time and increasing the sliding resistance between the wedge block A11 and the wedge block B31, so that the engagement between the wedge block A11 and the wedge block B31 is smoother.

[0063] On the basis of the above scheme, in order to realize the lifting function of the pull rope 21 on the aeration assembly 1, refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 The embodiment of the present application provides a specific implementation of the lifting assembly. The lifting assembly 2 also includes a winch 22 for winding the pull rope 21. The winch 22 is rotatably arranged on the top of the well top platform 101. The winch 22 is fixedly arranged on the outside of the drive shaft 23. The drive shaft 23 is linked with the driving end of the motor 24. The motor 24 is fixedly arranged on the outside of the aeration well 100. The drive shaft 23 is also linked with the wedge block B31 to drive the wedge block B31 to release the limit on the wedge block A11.

[0064] In a specific implementation, the motor 24 is started to drive the drive shaft 23 to rotate, so that the drive shaft 23 drives the outer capstan 22 to rotate, thereby realizing the retracting and releasing function of the pull rope 21, so that the pull rope 21 can drive the aeration assembly 1 to move up and down inside the aeration well 100.

[0065] On the basis of the above scheme, in order to realize the engagement and limiting function of the wedge block B31 on the wedge block A11, refer to Figure 1 , Figure 2 , Figure 5 and Figure 6 The locking assembly 3 also includes a bottom plate 32, which is slidably arranged at the bottom of the wedge block B31 to provide strength for the wedge block B31. A right-angle plate 33 is fixedly arranged on the top of the bottom plate 32. The right-angle plate 33 is fixedly arranged on the outside of the well top platform 101. A sliding rod A34 is slidably arranged on the inside of the right-angle plate 33. One end of the sliding rod A34 is fixedly connected to the wedge block B31. A spring A35 is arranged on the outside of the sliding rod A34 between the wedge block B31 and the right-angle plate 33. The other end of the sliding rod A34 is located on the outside of the right-angle plate 33 and is fixedly arranged with a connecting block 36.

[0066] In a specific implementation, when the wedge block A11 is located at the bottom of the wedge block B31, it first contacts the inclined surface of the wedge block B31, so that the wedge block B31 is squeezed and pushes the slide rod A34 to slide on the inner side of the right-angle plate 33. At the same time, the wedge block B31 slides on the top of the bottom plate 32 and gradually moves away from the side of the wedge block A11. At the same time, the wedge block B31 compresses the spring A35. When the wedge block A11 continues to rise and is located at the top of the wedge block B31, the spring A35 pushes the wedge block B31 to automatically reset and move to the bottom of the wedge block A11, thereby realizing the automatic limiting function of the wedge block A11, so as to limit the aeration assembly 1 lifted to the highest point.

[0067] On the basis of the above scheme, in order to realize the linkage function between the drive shaft 23 and the wedge block B31, refer to Figure 5 and Figure 6 , and also includes a movable block 5 arranged on the top of the well top platform 101. The movable block 5 is intermittently raised and lowered under the drive of the driving shaft 23. A connecting rod 51 is rotatably arranged on the outer side of the movable block 5, and the other end of the connecting rod 51 is rotatably arranged on one side of the connecting block 36.

[0068] In a specific implementation, the movable block 5 is driven to intermittently rise and fall by the driving shaft 23. During the rising process of the aeration component 1, the movable block 5 pushes and pulls the connecting block 36 through the connecting rod 51, and drives the wedge block B31 to slide back and forth through the connecting block 36. When the wedge block A11 moves to a certain height and is located at the bottom of the wedge block B31, the driving shaft 23 stops driving the movable block 5 to rise and fall. At this time, the wedge block B31 is not affected by the driving shaft 23 and automatically limits the wedge block A11. When the aeration component 1 needs to be lowered, the driving shaft 23 reverses a certain angle to drive the movable block 5 to rise and fall, so that the movable block 5 pushes and pulls the wedge block B31 through the connecting rod 51 to separate from the bottom of the wedge block A11, thereby realizing the driving function of the driving shaft 23 on the wedge block B31.

[0069] On the basis of the above scheme, in order to realize the driving function of the driving shaft 23 to the movable block 5, refer to Figure 1 , Figure 5 and Figure 6A cam 25 is fixedly disposed on the outer side of the driving shaft 23, and the cam 25 is located above the movable block 5;

[0070] In a specific implementation, a slide bar B52 is symmetrically fixed at the bottom of the movable block 5, a slide sleeve 53 is slidably arranged outside the slide bar B52, the slide sleeve 53 is fixed on the top of the well top platform 101, and a spring B54 is arranged outside the slide bar B52 between the movable block 5 and the slide sleeve 53.

[0071] In a specific implementation, the movable block 5 is pressed downward by the rotating cam 25, so that the movable block 5 pushes the slide bar B52 to slide downward on the inner side of the sliding sleeve 53, and at the same time compresses the spring B54. When the cam 25 is away from the top of the movable block 5, the movable block 5 is automatically reset under the action of the spring B54. At this time, the spring A35 pushes the wedge block B31 to automatically reset, so as to ensure that the wedge block B31 and the movable block 5 are reset synchronously and smoothly.

[0072] On the basis of the above scheme, in order to facilitate the maintenance work after the aeration assembly 1 is lifted, refer to Figure 1 , Figure 2 , Figure 4 and Figure 7 , and also includes a spray component 4, which is arranged above the aeration well 100. The spray component 4 includes a water pipe 41, which is slidably arranged above the aeration well 100. A plurality of nozzles 42 are fixedly arranged on the outside of the water pipe 41, and a connector 43 is fixedly arranged at one end of the water pipe 41. The water pipe 41 reciprocates under the drive of the driving shaft 23.

[0073] Specifically, when the drive shaft 23 drives the pull rope 21 to lift the aeration component 1 to move, the drive shaft 23 synchronously drives the water pipe 41 to move horizontally above the aeration well 100. When the aeration component 1 is out of the water surface, water is input into the water pipe 41 through the connector 43, and the water is sprayed toward the top of the aeration component 1 through the nozzle 42 to facilitate cleaning of the aeration component 1 and prevent the outside of the aeration component 1 from carrying a lot of stains that make maintenance operations inconvenient.

[0074] On the basis of the above scheme, in order to realize the driving function of the driving shaft 23 to the water pipe 41, refer to Figure 4 , Figure 5 and Figure 7 A gear A26 is fixedly provided on the outside of the driving shaft 23, and the gear A26 is linked with the reciprocating component 6 for driving the water pipe 41 to move.

[0075] On the basis of the above scheme, the embodiment of the present application provides a specific implementation of a reciprocating component, the reciprocating component 6 includes a reciprocating screw 61, the reciprocating screw 61 is rotatably arranged on both sides of the aeration well 100, a gear C62 is fixedly arranged at one end of the reciprocating screw 61, the gear C62 is meshed and arranged on the outside of the gear A26, a slider 63 is slidably arranged on the outside of the reciprocating screw 61 through a threaded groove, and the slider 63 is arranged at the bottom of the water pipe 41.

[0076] Specifically, when the drive shaft 23 rotates, the gear A26 drives the gear C62 to rotate, so that the gear C62 drives the reciprocating screw 61 to rotate on both sides of the aeration well 100, and then the reciprocating screw 61 drives the outer slider 63 to slide on the outside of the aeration well 100, and the slider 63 drives the water pipe 41 to translate above the aeration well 100, and can reciprocate on its own, so as to repeatedly flush the aeration assembly 1.

[0077] On the basis of the above scheme, in order to improve the cleaning effect of the spray component 4 on the aeration component 1, refer to Figure 1 and Figure 7 , further comprising a limit frame 7, the limit frame 7 is fixedly arranged outside the aeration well 100, an upper rack 71 and a lower rack 72 are fixedly arranged inside the limit frame 7 along the moving direction of the water pipe 41, and the upper rack 71 and the lower rack 72 are staggered along the moving direction of the water pipe 41;

[0078] Gears B44 are fixedly provided at both ends of the water pipe 41 . The gear B44 is located inside the limiting frame 7 . The gear B44 is alternately meshed with the upper rack 71 and the lower rack 72 .

[0079] Specifically, when the water pipe 41 translates, it drives the gears B44 at both ends to move inside the limit frame 7, so that the gear B44 is alternately meshed with the upper rack 71 and the lower rack 72, so that the water pipe 41 swings during the translation process driven by the gear B44, so that the nozzle 42 can clean the aeration assembly 1 from the side at different angles, thereby improving the cleaning effect.

[0080] In summary, when the liftable aerator disclosed in the embodiment of the present application is in use, air is input into the rubber hose 16 through the air inlet pipe 17, the air flows to the plurality of aeration pipes 15 through the connecting pipe 14, and is input into the aeration well 100 through the aeration pipes 15 for aeration. When the lift is to be maintained, the drive shaft 23 is driven to rotate by starting the motor 24, so that the drive shaft 23 drives the outer winch 22 to rotate, and the winch 22 tightens the pull rope 21, so that the pull rope 21 drives the lifting pipe 13 to move upward, so that the lifting pipe 13 moves along the vertical direction. The rod 12 slides to prevent the lifting pipe 13 from driving the aeration pipe 15 to swing inside the aeration well 100; at this time, the driving shaft 23 drives the outer cam 25 to rotate, and the rotating cam 25 presses the movable block 5 downward, so that the movable block 5 pushes the sliding rod B52 to slide downward on the inner side of the sliding sleeve 53, and at the same time compresses the spring B54, so that the movable block 5 pushes and pulls the connecting block 36 through the connecting rod 51 to move, and drives the wedge block B31 to slide through the connecting block 36. When the cam 25 is away from the top of the movable block 5, the movable block 5 is automatically moved under the action of the spring B54. When the wedge block A11 is moved to a certain height and is located at the bottom of the wedge block B31, the drive shaft 23 stops driving the movable block 5 to rise and fall. At this time, the wedge block B31 is automatically limited to the wedge block A11 without being affected by the drive shaft 23. Specifically, when the wedge block A11 contacts the wedge block B31, the outer roller 110 forms an extrusion thrust on the wedge block B31, so that the wedge block B31 is extruded and pushed. The movable slide bar A34 slides on the inner side of the right-angle plate 33, and the wedge block B31 slides on the top of the bottom plate 32 and gradually moves away from the side of the wedge block A11. At the same time, the wedge block B31 compresses the spring A35. When the wedge block A11 continues to rise and is located at the top of the wedge block B31, the spring A35 pushes the wedge block B31 to automatically reset and move to the bottom of the wedge block A11, realizing the automatic limit function of the wedge block A11, so as to limit the aeration assembly 1 lifted to the highest point, so as to ensure the stability of the aeration assembly 1 during the maintenance process;

[0081] In the process of driving the aeration assembly 1 to rise, the driving shaft 23 drives the gear C62 to rotate through the gear A26, so that the gear C62 drives the reciprocating screw 61 to rotate on both sides of the aeration well 100, and then drives the outer slider 63 to slide on the outside of the aeration well 100 through the reciprocating screw 61, and drives the water pipe 41 to translate above the aeration well 100 through the slider 63, and can reciprocate on its own, and the water pipe 41 drives the gears B44 at both ends to move inside the limit frame 7 when translating, so that The gear B44 is alternately meshed with the upper rack 71 and the lower rack 72, so that the water pipe 41 swings during the translation process driven by the gear B44, so that the nozzle 42 can clean the aeration component 1 from the side at different angles; when the aeration component 1 is out of the water surface, water is input into the water pipe 41 through the connector 43, and the water is sprayed toward the top of the aeration component 1 through the nozzle 42, so as to facilitate the cleaning of the aeration component 1 and prevent the outer side of the aeration component 1 from carrying a lot of stains and inconvenience for maintenance operations;

[0082] When the maintenance work is completed, the motor 24 drives the drive shaft 23 to reverse. The drive shaft 23 reverses a certain angle to drive the movable block 5 to rise and fall, so that the movable block 5 pushes and pulls the wedge block B31 to separate from the bottom of the wedge block A11 through the connecting rod 51. At the same time, the pull rope 21 can be loosened. When the wedge block B31 is separated from the bottom of the wedge block A11, the aeration assembly 1 can move directly to the bottom of the wedge block B31 under the action of its own gravity, so as to release the limit of the wedge block B31 on the wedge block A11.
