The outer wall of the aerator assembly is provided with a connecting pipe, which is connected to an air inlet pipe. The connecting pipe is provided with a protective device inside. However, the following defects still exist: the aeration holes of the existing aerator are prone to blockage when not in use, which affects the aeration effect of the subsequent aerator. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a disc-type microporous aerator to prevent sewage backflow, so as to solve the problems existing in the background art.

[0005] This utility model provides the following technical solution: a disc-type microporous aerator for preventing sewage backflow, comprising an arc-shaped base, with an integrally formed protrusion at the edge of the arc-shaped base, an inner mounting groove formed on the inner wall of the protrusion at the edge of the arc-shaped base, an inner aeration hood installed in the inner mounting groove, the inner aeration hood being detachably connected to the arc-shaped base by bolts, a cavity being left between the inner aeration hood and the arc-shaped base, an air inlet being formed at the top of the arc-shaped base, and a connecting cylinder communicating with the air inlet being fixedly connected to the bottom of the arc-shaped base. The upper surface of the internal aeration hood is provided with a plurality of evenly distributed internal aeration holes. The top of the protrusion at the edge of the arc-shaped base is rotatably connected to a ring sleeve. The inner wall of the ring sleeve is provided with an annular groove. A baffle that fits into the internal aeration hood is engaged in the annular groove. The top of the baffle is provided with a plurality of through holes aligned with the internal aeration holes. A plurality of protrusions are fixedly connected in the annular groove. A plurality of connecting grooves are provided at the edge of the baffle, and the protrusions engage with the connecting grooves. The outer side of the connecting cylinder is provided with a connecting component that allows the ring sleeve to rotate.

[0006] As a further embodiment of this utility model, the connecting assembly includes a rotating cylinder, which is rotatably connected to the outside of the connecting cylinder. A plurality of L-shaped support rods are fixedly connected to the outer circumferential wall of the rotating cylinder, and the L-shaped support rods are fixed to the ring sleeve.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model features a baffle. When not in use, rotating the ring causes the baffle to move, misaligning the through hole on the baffle with the inner aeration hole on the inner aeration hood. This causes the baffle to block and seal the inner aeration hole, preventing blockage and preventing sewage from flowing back into the aerator, thus improving the aerator's performance.

[0014] 2. By providing a guide groove, when gas enters between the arc-shaped chassis and the inner aeration hood through the connecting cylinder and the air inlet, the gas will be evenly distributed between the arc-shaped chassis and the inner aeration hood under the action of the guide groove, thereby enabling the aerator to output gas evenly and further improving the aerator's performance.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figures 1-4 This utility model provides a disc-type microporous aerator to prevent sewage backflow, including an arc-shaped base 12. The edge of the arc-shaped base 12 has an integrally formed protrusion. An inner mounting groove 13 is formed on the inner wall of the protrusion on the edge of the arc-shaped base 12. An inner aeration hood 15 is installed in the inner mounting groove 13. The inner aeration hood 15 is detachably connected to the arc-shaped base 12 by bolts. A cavity is left between the inner aeration hood 15 and the arc-shaped base 12. An air inlet 1 is formed on the top of the arc-shaped base 12. 0. A connecting cylinder 6 connected to the air inlet 10 is welded to the bottom of the arc-shaped chassis 12. Multiple evenly distributed internal aeration holes 16 are opened on the upper surface of the internal aeration hood 15. A ring sleeve 1 is rotatably connected to the top of the protruding edge of the arc-shaped chassis 12. An annular groove 14 is opened on the inner wall of the ring sleeve 1. A baffle 4 that fits snugly against the internal aeration hood 15 is engaged in the annular groove 14. Multiple through holes 17 aligned with the internal aeration holes 16 are opened on the top of the baffle 4. During use, the gas... The gas enters the connecting cylinder 6, and then enters the space between the arc-shaped base 12 and the inner aeration hood 15 through the air inlet 10. It then exits through the inner aeration hole 16 and the through hole 17. Multiple protrusions are welded into the annular groove 14. Multiple connecting grooves 18 are opened at the edge of the baffle 4, and the protrusions engage with the connecting grooves 18. A connecting component is provided on the outside of the connecting cylinder 6 to rotate the ring sleeve 1. When not in use, the ring sleeve 1 is rotated through the connecting component. At this time, since the protrusion in the annular groove 14 on the ring sleeve 1 engages with the connecting groove 18 on the baffle 4, the ring sleeve 1 will drive the baffle 4 to rotate through the protrusion, causing the through hole 17 on the baffle 4 to be misaligned with the inner aeration hole 16 on the inner aeration hood 15. At the same time, the baffle 4 will block and seal the inner aeration hole 16 on the inner aeration hood 15, thereby preventing the inner aeration hole 16 from becoming blocked and preventing sewage from flowing back into the aerator, thus improving the aerator's performance.

[0023] In this invention, the connecting assembly includes a rotating cylinder 7, which is rotatably connected to the outside of the connecting cylinder 6. Multiple L-shaped support rods 2 are welded to the outer circumference of the rotating cylinder 7, and the L-shaped support rods 2 are fixed to the ring sleeve 1. Multiple toothed grooves 8 are formed on the outer circumference of the rotating cylinder 7, allowing a rack to mesh with the toothed grooves 8 on the rotating cylinder 7. Moving the rack causes the rotating cylinder 7 to rotate, which in turn causes the ring sleeve 1 to rotate via the L-shaped support rods 2. An inner aeration hood 15 is attached to the edge of the inner aeration hood 15. A sealing ring is used to seal the gap between the inner aeration hood 15 and the arc-shaped base 12. By sealing the gap between the inner aeration hood 15 and the arc-shaped base 12, gas leakage can be prevented from the gap between the inner aeration hood 15 and the arc-shaped base 12. A sealing strip is glued to the edge of the baffle 4 to seal the gap between the baffle 4 and the ring 1. By sealing the gap between the baffle 4 and the ring 1, gas leakage can be prevented from the gap between the baffle 4 and the ring 1, thus improving the sealing performance of the aerator.

[0024] In particular, the upper surface of the arc-shaped chassis 12 is provided with multiple guide grooves 11 that communicate with the air inlet 10. When the gas enters between the arc-shaped chassis 12 and the inner aeration hood 15 through the air inlet 10, the gas will flow along the guide grooves 11, so that the gas is evenly distributed between the arc-shaped chassis 12 and the inner aeration hood 15 under the action of the guide grooves 11, thereby achieving uniform gas discharge. Multiple ribs 5 are welded to the bottom of the arc-shaped chassis 12, and the ribs 5 are fixed to the connecting cylinder 6. The installation of ribs 5 at the bottom of the arc-shaped chassis 12 strengthens the overall strength of the arc-shaped chassis 12, thereby increasing the strength of the arc-shaped chassis 12. A connecting sleeve 3 is welded to the bottom end of the connecting cylinder 6, and an internal thread 9 is integrally formed inside the connecting sleeve 3.

[0025] The working principle of this utility model is as follows: When needed, the air inlet pipe is connected to the connecting sleeve 3 via the internal thread 9, allowing gas to enter the connecting cylinder 6. The gas then enters the space between the arc-shaped base 12 and the inner aeration hood 15 through the air inlet hole 10. Simultaneously, the gas flows along the guide groove 11, ensuring even distribution between the arc-shaped base 12 and the inner aeration hood 15 under the influence of the guide groove 11. The gas then exits through the inner aeration hole 16 and the through hole 17. When not in use, the rack engages with the toothed groove 8 on the rotating cylinder 7, allowing the rack to... As the aerator moves, the rack drives the rotating cylinder 7 to rotate, which in turn drives the ring sleeve 1 to rotate via the L-shaped support rod 2. At this time, because the protrusion in the annular groove 14 on the ring sleeve 1 engages with the connecting groove 18 on the baffle 4, the ring sleeve 1 drives the baffle 4 to rotate via the protrusion, causing the through hole 17 on the baffle 4 to be misaligned with the inner aeration hole 16 on the inner aeration hood 15. At the same time, the baffle 4 blocks and seals the inner aeration hole 16 on the inner aeration hood 15, thereby preventing the inner aeration hole 16 from becoming blocked and preventing sewage from flowing back into the aerator, thus improving the aerator's performance.

[0026] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection.
