Description

Technical Field

[0001] This utility model relates to the field of aerator support tube technology, specifically a microporous tubular aerator support tube. Background Technology

[0002] An aeration pipe is a device used in water treatment, wastewater treatment, and other fields. Its main purpose is to inject air or oxygen into liquids to promote the dissolution and mixing of oxygen in the water. It is commonly used in wastewater treatment processes such as activated sludge processes, aeration tanks, and oxidation ditches to help microorganisms decompose organic pollutants. Aeration pipe support pipes are auxiliary devices used to fix and support the aeration pipes, usually installed at the bottom of aeration tanks or oxidation ditches. Their main function is to ensure the aeration pipes maintain a stable position in the water, preventing displacement or damage due to water flow or air bubble impact, while also ensuring uniform air bubble release and improving aeration efficiency.

[0003] However, most existing aeration pipes are installed by directly supporting them with a support tube. If the axes of the two ends of the aeration pipe are not aligned or are tilted or offset during the installation, the air bubbles and surging water flow generated during subsequent use in the aeration tank can easily cause the connection of the aeration pipe to loosen, thus affecting the use of the aeration pipe.

[0004] In view of this, we propose a microporous tubular aerator support tube. Utility Model Content

[0005] The purpose of this utility model is to provide a microporous tubular aerator support tube, which solves the problem that the axis of the aerator tube may shift after connection, thus affecting its long-term use.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A microporous tubular aerator support tube includes a mounting base, an aeration tube body, and a connector. A vertical pipe is fixedly connected to the top surface of the mounting base, and the connector passes through the aeration tube body and is fixedly connected.

[0008] It also includes a positioning component to prevent the aeration pipe body from shifting during connection, which could cause the aeration pipe body to loosen during use.

[0009] The limiting component is used to prevent the aeration pipe from denting and deforming due to excessive fixing force when fixing the aeration pipe body;

[0010] The positioning component includes a ring, the bottom surface of which is fixedly connected to the top surface of the riser. A push post is slidably connected through the inside of the ring. A positioning block is fixedly connected to one end of the push post near the center of the ring. A rotating ring is rotatably connected to the surface of the ring. A plug rod is fixedly connected to the side of the rotating ring away from the ring. A threaded sleeve is slidably connected to one end of the plug rod away from the rotating ring. A lever is rotatably connected through the inside of the push post. An arc-shaped groove is formed on the side of the rotating ring near the lever. An externally threaded post is fixedly connected to the surface of the ring.

[0011] Preferably, the external threaded post passes through the threaded sleeve, and the threaded sleeve is threadedly connected to the external threaded post.

[0012] Preferably, the lever is inserted into the inner side of the arc-shaped groove on the side closest to the arc-shaped groove, and the lever is slidably connected to the arc-shaped groove.

[0013] Preferably, the number of positioning blocks is six groups, and the six groups of positioning blocks are arranged in a circular array with the center line of the ring as the axis.

[0014] Preferably, the limiting component includes a connecting rod that passes through and is slidably connected to the push column. A hinge plate is fixedly connected to the top end of the connecting rod. A hinge rod passes through and is hinged to the surface of the hinge plate. A square rod passes through and is hinged to the end of the hinge rod away from the hinge plate.

[0015] Preferably, a spring is fixedly connected to the top surface of the hinge plate, the end of the spring away from the hinge plate is fixedly connected to the inner wall of the push column, and a trigger plate is fixedly connected to the end of the connecting rod away from the hinge plate.

[0016] Preferably, a limiting groove is formed on the inner side of the ring, and a limiting block is fixedly connected to the inner side of the limiting groove.

[0017] By employing the above technical solution, this utility model provides a microporous tubular aerator support tube. It possesses at least the following beneficial effects:

[0018] (1) This utility model achieves this by rotating the ring so that the arc groove rotates along with the ring. When the lever is moved by the rotating arc groove, the lever slides along the arc groove, causing the push column to push the positioning block to move gradually toward the aeration pipe body. By having six sets of positioning blocks arranged in a circular array move toward the axis of the ring at the same time, it can ensure that the axis of the aeration pipe body is consistent with the axis of the ring. With the symmetrically arranged positioning components, it can ensure that the axis of the aeration pipe body will not shift after the connection is completed, thus avoiding the instability of subsequent use caused by the axis shift of the aeration pipe body during connection.

[0019] (2) In this utility model, when the trigger plate moves the push connecting rod toward the inside of the push column, the hinge rod pushes the square rod out of the push column and inserts between the limiting blocks in the limiting groove, so that the push column can no longer move. At the same time, the screw sleeve is resisted and can no longer be tightened. This avoids the push column continuously pushing the positioning block, which would cause the positioning block to have too much fixing force on the aeration pipe body and cause the aeration pipe body to be dented and deformed. When the aeration pipe body is aligned on the axis for connection, the connection is more stable. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] A microporous tubular aerator support tube, such as Figures 1-4 As shown, the device includes a mounting base 1, an aeration pipe body 5, and a connector 6. A riser pipe 4 is fixedly connected to the top surface of the mounting base 1, and the connector 6 passes through and is fixedly connected to the aeration pipe body 5. It also includes a positioning component 2 to prevent the aeration pipe body 5 from shifting during connection, thus preventing loosening during use; and a limiting component 3 to prevent excessive fixing force from causing the aeration pipe to dent or deform. The positioning component 2 includes a ring 21, the bottom surface of which is fixedly connected to the top surface of the riser pipe 4, and the interior of the ring 21... A push post 22 is slidably connected to the ring 21. A positioning block 23 is fixedly connected to one end of the push post 22 near the axis of the ring 21. A rotating ring 24 is rotatably connected to the surface of the ring 21. An insert rod 25 is fixedly connected to the side of the rotating ring 24 away from the ring 21. A threaded sleeve 26 is slidably connected to one end of the insert rod 25 away from the rotating ring 24. A lever 27 is rotatably connected to the inner side of the push post 22. An arc groove 28 is opened on the side of the rotating ring 24 near the lever 27. An external threaded post 29 is fixedly connected to the surface of the ring 21.

[0031] First, the external threaded post 29 passes through the threaded sleeve 26, and the threaded sleeve 26 is threadedly connected to the external threaded post 29. Through the threaded sleeve 26 and the threaded external threaded post 29, the threaded sleeve 26 can achieve a self-locking function, preventing the threaded sleeve 26 from reversing and resetting.

[0032] Secondly, the lever 27 is inserted into the inner side of the arc-shaped groove 28 on the side closest to the arc-shaped groove 28, and the lever 27 is slidably connected to the arc-shaped groove 28. Since the lever 27 is inserted into the arc-shaped groove 28 and slidably connected, and the lever 27 passes through the push post 22 and is rotatably connected, the push post 22 is limited by the ring 21. When the lever 27 is moved by the rotating arc-shaped groove 28, the lever 27 will slide along the arc-shaped groove 28.

[0033] Furthermore, there are six sets of positioning blocks 23, and the six sets of positioning blocks 23 are arranged in a circular array with the center line of the ring 21 as the axis. By using the six sets of circularly arranged positioning blocks 23 in conjunction with the arc groove 28 of the circular array, the positioning blocks 23 can move towards the center of the ring 21 at the same time, thereby avoiding the axial displacement of the aeration pipe body 5.

[0034] In this embodiment, when the aeration pipe body 5 is installed in the aeration tank, the mounting base 1 is first installed to the aeration tank with bolts, and then the aeration pipe body 5 is inserted into the ring 21. At this time, the threaded sleeve 26 is not turned first. Multiple sets of aeration pipe bodies 5 are connected by the connector 6. Then the threaded sleeve 26 is turned so that the threaded sleeve 26 is gradually tightened with the external threaded post 29. During the turning of the threaded sleeve 26, the insert rod 25, which is inserted into the inner side of the threaded sleeve 26 and is slidably connected, will rotate together. The insert rod 25 will drive the fixedly connected rotating ring 24 to rotate together. When the rotating ring 24 rotates, the arc groove 28 will rotate along with the rotating ring 24. Since the lever 27 is inserted into the arc groove 28 and is slidably connected, and the lever 27 passes through the push post 22 and The rotating connection allows the push post 22 to pass through the ring 21 and slide, thus limiting the push post 22 to the position of the ring 21. When the lever 27 is moved by the rotating arc groove 28, the lever 27 will slide along the arc groove 28, but the lever 27 will only drive the push post 22 to slide within the ring 21, causing the push post 22 to push the positioning block 23 to gradually move towards the aeration pipe body 5. By having six sets of circumferentially arrayed positioning blocks 23 move simultaneously towards the axis of the ring 21, it can be ensured that the axis of the aeration pipe body 5 is consistent with the axis of the ring 21. With the symmetrically arranged positioning components 2, it can be ensured that the axis of the aeration pipe body 5 will not shift after the connection is completed, avoiding the instability of subsequent use caused by the axis shift of the aeration pipe body 5 during connection.

[0035] Example 2

[0036] like Figures 5-6 As shown, the limiting component 3 includes a connecting rod 31, which passes through the push post 22 and is slidably connected. A hinge plate 32 is fixedly connected to the top end of the connecting rod 31. A hinge rod 33 passes through and is hinged to the surface of the hinge plate 32. A square rod 34 passes through and is hinged to the end of the hinge rod 33 away from the hinge plate 32.

[0037] A spring 35 is fixedly connected to the top surface of the hinge plate 32. The end of the spring 35 away from the hinge plate 32 is fixedly connected to the inner wall of the push column 22. A trigger plate 36 is fixedly connected to the end of the connecting rod 31 away from the hinge plate 32. When the trigger plate 36 is in contact with the surface of the aeration pipe body 5, the push column 22 will continue to move if the screw sleeve 26 is turned. Then, the trigger plate 36 will retract into the positioning block 23 after being resisted by the surface of the aeration pipe body 5.

[0038] Furthermore, a limiting groove 37 is provided on the inner side of the ring 21, and a limiting block 38 is fixedly connected to the inner side of the limiting groove 37. When the square rod 34 is inserted between the limiting blocks 38 in the limiting groove 37, the limiting block 38 will block the push column 22 to continue sliding through the square rod 34.

[0039] In this embodiment, when the positioning block 23 is pushed by the push column 22 and gradually approaches the aeration pipe body 5, the push column 22 will drive the spring 35 and the hinge plate 32 to move together. This causes the hinge plate 32 to drive the trigger plate 36 to move along with the positioning block 23 via the connecting rod 31. When the trigger plate 36 is in contact with the surface of the aeration pipe body 5, continuing to tighten the screw sleeve 26 will cause the push column 22 to continue moving. Then, the trigger plate 36, after being resisted by the surface of the aeration pipe body 5, will relatively retract into the positioning block 23. When the push column 22 moves, the trigger plate 36 relatively pushes the connecting rod 31 to move inwards towards the push column 22, thus connecting... Rod 31 pushes hinge plate 32 to slide inside push post 22, further causing hinge plate 32 to push hinge rod 33 and force hinge rod 33 to rotate to a certain extent. This causes hinge rod 33 to push square rod 34 out of push post 22 and insert it between limit blocks 38 in limit groove 37, thus preventing push post 22 from moving further. At the same time, screw sleeve 26 is resisted and can no longer be tightened. This avoids push post 22 continuously pushing positioning block 23, which would cause positioning block 23 to have excessive fixing force on aeration pipe body 5 and cause aeration pipe body 5 to be dented and deformed. When aeration pipe body 5 is connected with the axis aligned, the connection is more stable.
