Technical Field

[0001] The utility model relates to the field of wastewater treatment devices, and more particularly to a liftable aeration pipe. Background Art

[0002] Liftable aeration tubes are essential equipment for sewage oxygenation and aeration treatment. They are widely used in biochemical treatment projects of urban domestic sewage and industrial wastewater (such as petrochemical, textile, oil refining, coking, papermaking, printing and dyeing, slaughtering, brewing, pharmaceutical, leather making and other industries). By injecting air into the sewage, the dissolved oxygen content in the water is increased, the growth and activity of microorganisms are promoted, and the oxidation and decomposition process of the sewage is accelerated.

[0003] Aeration pipes are usually used in groups at the same time, and each aeration pipe is installed with an elbow. The existing elbows rely on manual installation, which is inefficient and the direction of each elbow cannot be kept consistent after installation.

[0004] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

DETAILED DESCRIPTION

[0021] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0022] Liftable aeration pipe, such as Figures 1 to 4As shown, it includes a frame 1, on which are installed several aeration pipe bodies 2, one end of the aeration pipe body 2 is provided with a connector 3, a fixing plate 4 is slidably connected to the frame 1, a groove 5 is provided on the fixing plate 4, an extrusion block 6 is slidably connected to the fixing plate 4, and several elbows 7 that are engaged with the connector 3 are clamped between the extrusion block 6 and the groove wall of the groove 5. The number of the elbows 7 corresponds to the number of the connectors 3. By arranging the aeration pipe body 2 on the frame 1, the aeration function is realized, and a sliding fixing plate 4 is provided on the frame 1. The sliding extrusion block 6 on the fixing plate 4 can fix the elbow 7, and then when the fixing plate 4 slides toward the frame 1, the elbow 7 is engaged with the connector 3, so that all the elbows 7 are installed on the corresponding connector 3. The aeration pipe body 2 is made of ABS material, which has good corrosion resistance and improves the service life of the aeration pipe body 2.

[0023] like Figure 4 As shown, a sliding cavity 8 is provided on the groove wall of the groove 5, so that the extrusion block 6 can slide in the sliding cavity 8. A compression spring 9 is provided between the extrusion block 6 and the bottom of the sliding cavity 8. The compression spring 9 can provide the extrusion block 6 with the force to squeeze the elbow 7, so as to clamp the elbow 7. A limiting block 10 is integrally formed on the elbow 7, and an embedding groove 11 for engaging with the limiting block 10 is provided on the fixing plate 4. When the limiting block 10 on the elbow 7 is embedded in the embedding groove 11, the installation angle of the elbow 7 can be fixed to prevent the elbow 7 from rotating, and a plurality of elbows 7 can be installed in a unified manner. When fixing the elbow 7, the operator pulls the extrusion block 6. During this process, the extrusion block 6 can slide in the sliding cavity 8. At the same time, the compression spring 9 is elastically deformed after being squeezed by the extrusion block 6. Then the operator picks up the elbow 7 and aligns the limit block 10 on the elbow 7 with the embedding groove 11, and then puts the elbow 7 into the groove 5. Then the operator releases the extrusion block 6. At this time, the compression spring 9 recovers its elastic deformation and pushes the extrusion block 6. Then the extrusion block 6 squeezes the elbow 7 to complete the fixation. Then the operator fixes all the elbows 7 to the fixing plate 4 in turn.

[0024] like Figure 2 and Figure 3As shown, two guide posts 12 are fixedly connected to the fixing plate 4, and two guide grooves 13 for sliding the guide posts 12 are provided on the frame 1. The guide posts 12 slide in the guide grooves 13 to achieve the approach or distance of the fixing plate 4. When the fixing plate 4 is fitted to the frame 1, the elbow 7 is installed on the connector 3. A fixing hole 14 communicating with the guide groove 13 is provided on the fixing plate 4, and a threaded hole 15 is provided on the guide post 12. Bolts 16 are provided in the fixing hole 14 and the threaded hole 15. When installing the elbow 7 to the connector 3, the operator first applies a layer of glue on the connector 3, and then the operator aligns the guide post 12 with the guide groove 13. Then the operator pushes the fixing plate 4 toward the frame 1. During the process, the guide column 12 moves in the guide groove 13. When the guide column 12 completely enters the guide groove 13, the elbow 7 is fixed to the connector 3, and the fixing hole 14 and the threaded hole 15 are connected. Then the operator screws the bolt 16 into the fixing hole 14 and the threaded hole 15 to complete the fixing of the fixing plate 4 to the frame 1. The groove wall of the groove 5 and the side of the extrusion block 6 facing the elbow 7 are both bonded with a sealing tape 17 by glue. After the extrusion block 6 clamps the elbow 7, the sealing tape 17 fits the elbow 7 to achieve a sealing effect, preventing external sewage from entering the connection between the elbow 7 and the connector 3. The side of the fixing plate 4 facing the frame 1 is also bonded with a sealing sheet 18 by glue to achieve sealing between the fixing plate 4 and the frame 1.
