Abstract
Description
Technical Field
[0001] This utility model relates to the field of lifting aeration pipe technology, specifically to a lifting aerator. Background Technology
[0002] The main function of an aerator is to increase the dissolved oxygen content in water by injecting air into it, thereby promoting biological activity and oxidation reactions in the water. In wastewater treatment, aerators provide sufficient oxygen to microorganisms, which helps degrade and oxidize organic matter in wastewater, improving wastewater treatment efficiency.
[0003] Typically, aerators are arranged at the bottom of the sewage tank. When the aerators become clogged or damaged, it is inconvenient to remove them from the sewage for cleaning and maintenance.
[0004] In response, lift-type aerators were developed. See also Figure 1 The lift-type aerator includes a main air supply pipe 1, the lower side of which is connected to an air supply branch pipe 2. The lower end of the air supply branch pipe 2 is connected to a receiving pipe 4 via a quick connector 5. The lower end of the receiving pipe 4 is connected to an aeration pipe 7. When it is necessary to remove the aerator 7 from the sewage, the worker separates the receiving pipe 4 from the air supply branch pipe 2, and then lifts the receiving pipe 4 away from the sewage. The receiving pipe 4 pulls the aeration pipe 7 away from the sewage, making it convenient for the worker to clean and maintain the aeration pipe 7.
[0005] However, during the process of disassembling the receiving pipe and the gas branch pipe, the receiving pipe is a straight pipe with a slippery surface, which increases the chance of slipping and thus increases the risk of the receiving pipe falling, reducing the reliability of operation. Utility Model Content
[0006] To address the aforementioned shortcomings of existing technologies, this invention proposes a lifting aerator. This invention reduces the risk of the receiving pipe falling when disassembling the receiving pipe and the gas supply branch pipe, thereby improving operational reliability.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0008] A lifting aerator includes a main gas supply pipe, a branch gas supply pipe, a receiving pipe, a quick connector, a support frame, and an aeration pipe. The branch gas supply pipe is horizontally located on the side of the main gas supply pipe. The upper end of the receiving pipe has a bend that turns horizontally. The bend is connected to the branch gas supply pipe via a quick connector. The quick connector is a quick-connect fitting. The main gas supply pipe is equipped with a support frame with an elongated opening. The long side of the elongated opening is perpendicular to the extension direction of the main gas supply pipe. The receiving pipe is located inside the elongated opening. The side wall of the receiving pipe has a limiting part located on the top surface of the support frame. The lower end of the receiving pipe is equipped with an aeration pipe.
[0009] Furthermore, the gas supply branch pipes are symmetrically arranged on the left and right sides of the main gas supply pipe.
[0010] Furthermore, the support frame includes a support plate, a fixed clamp, and a movable clamp. The end of the support plate is provided with the elongated opening, and the top surface of the support plate is provided with a fixed clamp. The fixed clamp is connected to the movable clamp through a fastening assembly. The fixed clamp and the movable clamp encircle the gas transmission main pipe.
[0011] Furthermore, there are two fixing clamps.
[0012] Furthermore, the support plate is provided with several weight-reduction holes.
[0013] Furthermore, the limiting part includes two ear plates symmetrically disposed on the outer side wall of the receiving pipe.
[0014] The beneficial effects of this utility model are:
[0015] 1. During the disassembly of the receiving pipe and the gas transmission branch pipe, workers can grasp the part of the receiving pipe near the bend and pull it off horizontally. During the pulling operation, if the hand slips, the limiting part can be supported by the support plate in the support frame, reducing the risk of the receiving pipe falling. Workers do not need to retrieve the receiving pipe that has fallen into the sewage and the aeration pipe located at the lower end of the receiving pipe, thus improving the reliability of the operation.
[0016] 2. The elbow design also makes it easier for workers to grip the connector when inserting or removing it. Workers can grip the part of the connector near the elbow, which is positioned above their hands, further reducing the risk of the connector slipping and falling, and improving operational reliability.
[0017] 3. Installing branch pipes on both sides of the main gas supply pipe can balance the forces on both sides of the main gas supply pipe, which helps to improve stability; in addition, more branch pipes can be installed on the main gas supply pipe to increase the aeration volume and improve the aeration effect.
[0018] 4. By using fixed clamps, movable clamps, and fastening components, the support frame and the gas transmission main pipe can be easily assembled.
[0019] 5. Two fixing clamps are provided on the support plate, which can increase the contact area between the support frame and the gas transmission branch pipe, and improve the reliability of the assembly of the support frame and the gas transmission branch pipe together.
[0020] 6. Several weight-reducing holes are provided on the support plate. The weight-reducing holes can reduce the weight of the support plate, thereby reducing the load on the gas transmission main pipe and improving the stability of the gas transmission main pipe. Attached Figure Description

[0039] Example 1:
[0040] See Figures 2 to 8 A lifting aerator includes a main gas supply pipe 1, a branch gas supply pipe 2, a receiving pipe 4, a quick connector 5, a support frame 8, and an aeration pipe 7.
[0041] A gas branch pipe 2 is fixedly installed on the side of the main gas supply pipe 1, extending horizontally. In the first configuration, the gas branch pipe 2 is installed on one side (left or right) of the main gas supply pipe 1. This configuration results in uneven stress on the left and right sides of the main gas supply pipe 1, which is detrimental to stability. For the second configuration, see [link to configuration]. Figure 2 , Figure 4 and Figure 6 The method involves installing air supply branch pipes 2 on both the left and right sides of the main air supply pipe 1. This method can balance the forces on the left and right sides of the main air supply pipe 1, which is beneficial to improving stability. In addition, this method can also lay more air supply branch pipes 2 on the main air supply pipe 1 to increase the aeration volume and improve the aeration effect.
[0042] See Figure 6 When in use, both ends of the gas transmission main pipe 1 must be fixedly installed on the top of the sewage tank 3 wall. The front end of the gas transmission main pipe 1 is connected to the external gas supply equipment, and the rear end of the gas transmission main pipe 1 is closed. The external gas supply equipment sends gas into the gas transmission main pipe 1.
[0043] See Figure 2 , Figure 3 and Figure 4 The upper end of the receiving pipe 4 is provided with a bend 41 that turns horizontally, and the bend 41 is an integral structure with the receiving pipe 4. The bend 41 is connected to the end of the gas branch pipe 2 away from the main gas pipe 1 via a quick connector 5. The quick connector 5 is a quick-connect coupling, which is an existing product, and the connection and disconnection are achieved by insertion and removal. Because the gas branch pipe 2 extends horizontally and the bend 41 faces horizontally, the insertion and removal of the receiving pipe 4 are also performed horizontally.
[0044] See Figure 2 and Figure 3An adapter 6 is fixedly installed at the lower end of the receiving pipe 4. The adapter 6 has one inlet and multiple outlets. In this embodiment, the adapter 6 has four outlets. The inlet is connected to the receiving pipe 4, and all four outlets are connected to the aeration pipe 7.
[0045] See Figure 5 The support frame 8 includes a support plate 81, a fixed clamp 82, and a movable clamp 83. The end of the support plate 81 has an elongated opening 811, the long side of which is perpendicular to the extension direction of the main gas supply pipe 1. When the receiving pipe 4 is inserted or removed in the horizontal direction, the receiving pipe 4 can move along the long side of the elongated opening 811.
[0046] When the main gas supply pipe 1 has a branch pipe 2 on only one side, the support plate 81 also has an elongated opening 811 on only one end. See Figure 2 , Figure 3 and Figure 4 When gas supply branch pipes 2 are provided on both the left and right sides of the main gas supply pipe 1, long strip openings 811 are provided on both the left and right ends of the support plate 81.
[0047] Two fixing clamps 82 are welded and fixed to the top surface of the support plate 81. When the main gas supply pipe 1 has a gas supply branch pipe 2 on only one side, one gas supply branch pipe 2 is located between the two fixing clamps 82. See Figure 2 , Figure 3 and Figure 4 When gas supply branch pipes 2 are installed on both the left and right sides of the main gas supply pipe 1, the two gas supply branch pipes 2 on the left and right sides are located between two fixed clamps 82. The fixed clamps 82 are assembled together with the movable clamps 83 by fastening components, and the fixed clamps 82 and the movable clamps 83 encircle the main gas supply pipe 1.
[0048] See Figure 5 The fastening assembly includes a bolt 84 and a nut 85. The bolt 84 is welded and fixed to the end of the fixed clamp 82. The bolt 84 extends upward through the end of the movable clamp 83. The nut 85 is threaded onto the bolt 84. The nut 85 and the end of the fixed clamp 82 together clamp the end of the movable clamp 83, thus completing the assembly of the fixed clamp 82 and the movable clamp 83.
[0049] By using fixed clamps 82, movable clamps 83, and fastening components, the support frame 8 can be easily assembled with the gas transmission main pipe 1. Two fixed clamps 82 are provided on the support plate 81, which can increase the contact area between the support frame 8 and the gas transmission branch pipe 2, and improve the reliability of the assembly of the support frame 8 and the gas transmission branch pipe 2.
[0050] See Figure 5In order to reduce the load on the gas transmission main pipe 1, a number of weight reduction holes 812 are provided on the support plate 81. The weight reduction holes 812 can reduce the weight of the support plate 81, thereby reducing the load on the gas transmission main pipe 1 and improving the stability of the gas transmission main pipe 1.
[0051] See Figure 2 and Figure 3 The side wall of the receiving pipe 4 is provided with a limiting part, which includes two ear plates 42 symmetrically welded to the side wall of the receiving pipe 4. When the elbow 41 at the upper end of the receiving pipe 4 is connected to the gas branch pipe 2 through the quick connector 5, the ear plates 42 on the receiving pipe 4 are located on the top surface of the support plate 81, so that the receiving pipe 4 is supported by the support plate 81, which helps to maintain the stability of the receiving pipe 4.
[0052] In use, the gas is sequentially ejected into the sewage through the main gas supply pipe 1, the branch gas supply pipe 2, the elbow 41 of the receiving pipe 4, the receiving pipe 4, the adapter 6, the aeration pipe 7, and the micropores on the aeration pipe 7. The gas oxidizes and decomposes the organic matter in the sewage, thereby achieving sewage treatment.
[0053] When cleaning and maintenance of the aeration pipe 7 is required, firstly, the elbow 41 at the upper end of the receiving pipe 4 is pulled horizontally away from the air supply branch pipe 2. During this pulling process, the receiving pipe 4 has not yet moved out of the long opening 811. Then, the receiving pipe 4 is moved horizontally out of the long opening 811. Finally, the receiving pipe 4 is lifted upwards, and the receiving pipe 4 drives the aeration pipe 7 away from the sewage in the sewage tank 3. Workers can then clean and maintain the aeration pipe 7 that has been taken out of the water.
[0054] During the process of disassembling the receiving pipe 4 and the gas supply branch pipe 2, the worker can grab the part of the receiving pipe 4 near the bend 41 and pull it off horizontally. During the pulling off operation, if the hand slips, the limiting part can be supported by the support plate 81 in the support frame 8, reducing the risk of the receiving pipe 4 falling. There is no need for the worker to retrieve the receiving pipe 4 that has fallen into the sewage and the aeration pipe 7 located at the lower end of the receiving pipe 4, which improves the reliability of the operation.
[0055] Furthermore, the elbow 41 is designed to facilitate gripping by workers during insertion and removal. Workers can grip the part of the connector 4 near the elbow 41, with the elbow 41 positioned above their hands, further reducing the risk of the connector 4 slipping and falling, and thus improving operational reliability.
[0056] Example 2:
[0057] This embodiment 2 illustrates one structure of the quick-connect connector from embodiment 1. See also... Figure 7 and Figure 8 The quick-connect fitting includes a female connector 51, a sealing ring 52, a return spring 53, a movable sleeve 54, a limit ring 55, a ball 56, and a male connector 57.
[0058] See Figure 7 and Figure 8 The left end of the female connector 51 has an internal thread, which is used to assemble with the right end thread of the gas transmission branch pipe 2. The inner side of the right end of the female connector 51 has a first step 511 with a sealing ring groove, and a sealing ring 52 is placed in the sealing ring groove. The outer side of the right end of the female connector 51 has a second step 512, and a return spring 53 is fitted onto the right end of the female connector 51. The left end of the return spring 53 abuts against the second step 512. A movable sleeve 54 is fitted onto the outer side of the return spring 53. A pressing ring 541 is located inside the movable sleeve 54. A third step 5411 is located on the left side of the pressing ring 541, and a fourth step 5412 is located on the right side of the pressing ring 541. The right end of the return spring 53 abuts against the third step 5411. A limiting ring 55 is also welded and fixed to the outer wall of the right end of the female connector 51. The limiting ring 55 is used to abut against the fourth step 5412 and prevents the movable sleeve 54 from disengaging from the female connector 51. The right end of the female connector 51 is also provided with a plurality of holding holes 513. A ball 56 is placed in the holding hole 513. The lower side of the hole wall of the holding hole 513 is a spherical hole wall 5131 that fits the ball 56 and prevents the ball 56 from falling completely into the inner cavity of the female connector 51.
[0059] See Figure 7 and Figure 8 The male connector 57 has an internal thread on its right end, which is used to connect with the elbow 41 at the upper end of the connector 4. The outer wall of the left end of the male connector 57 has an annular boss 571 and an annular groove 572. The left side of the annular boss 571 has a first inclined surface 5711, and the right side of the annular boss 571 has a second inclined surface 5712.
[0060] When connecting the elbow 41 at the upper end of the receiving pipe 4 to the gas branch pipe 2:
[0061] The worker uses one hand to push the movable sleeve 54 to the left, overcoming the elastic force of the return spring 53, so that the pressing ring 541 no longer obstructs the ball 56. Furthermore, the inner wall 542 of the right end of the movable sleeve prevents the ball 56 from completely disengaging from the receiving hole 513. The worker's other hand inserts the male connector 57 at the left end of the elbow 41 into the female connector 51. During insertion, the first inclined surface 5711 pushes the ball 56, causing it to move upwards towards the receiving hole 513. As insertion continues, the second inclined surface 5712 contacts the ball 56, causing it to move downwards into the annular groove 572 within the receiving hole 513. At this point, the left end of the male connector 57 presses against the sealing ring 52. Finally, the worker releases the movable sleeve 54, which moves to the right under the elastic force of the return spring 53. The pressing ring 541 presses back onto the outside of the ball 56, restricting the left and right movement of the male connector 57, thus achieving the insertion assembly.
[0062] When disassembling the elbow 41 at the upper end of the receiving pipe 4 and the gas transmission branch pipe 2:
[0063] The worker uses one hand to overcome the elastic force of the return spring 53 and pushes the movable sleeve 54 to the left, so that the pressing ring 541 no longer obstructs the ball 56. The worker's other hand can then pull the male connector 57 away from the female connector 51 to the left. During the pulling process, the second inclined surface 5712 pushes the ball 56, causing the ball 56 to move upwards towards the receiving hole 513. At this time, the ball 56 will not obstruct the pulling out of the male connector 57.
[0064] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
