[0002] Aeration is a common method in sewage treatment. In the ABR reaction tank, a frame aeration structure is generally used, that is, four interconnected main pipes are arranged on the four sides, and multiple parallel and spaced tubes with smaller diameters are arranged between the pipes on the two opposite sides. The surface of these tubes with smaller diameters is provided with micropores. Some manufacturers also use a fishbone aeration structure, that is, a main pipe in the middle, and multiple tubes with smaller diameters are arranged on the main pipe in parallel and spaced. Regardless of the above structure, the aeration structure is an integral structure, which needs to be welded on site during installation, and it is very inconvenient to remove the whole during maintenance. In order to solve the above problems, some manufacturers divide the frame aeration structure and the fishbone aeration structure into multiple parts, for example: the frame aeration structure is divided into two symmetrical parts, which are placed at the bottom of the reaction tank and then connected to the main pipeline through a connecting pipe; the fishbone aeration structure is divided into several fishbone structures of the same size, and then hoisted at the bottom of the reaction tank through a connecting pipe at intervals. However, in actual use, the above layout method still has the problem of inconvenience in installation and maintenance. Utility Model Content

[0024] An aeration base includes a base 2, wherein a plurality of communication ports 7 are arranged on the outer surface of the base, each of which can be detachably installed with an aeration pipe 3 for aeration or a detachably installed with a plugging cover 6 for blocking, and a flange 1 is arranged on the upper end surface of the base, and an opening 14 at the center of the flange is connected with all the communication ports.

[0025] At least two communication ports are symmetrically arranged on the outer surface of the base, and the number of communication ports arranged on the outer surface of the base on one side of the two communication ports is the same as the number of communication ports arranged on the outer surface of the base on the other side of the two communication ports. The two symmetrically arranged communication ports are used to connect the two aeration pipes respectively and can be arranged on the side of the bottom of the reaction tank. Figure 1The two structures above and below the middle part have an aeration pipe installed at each of the connecting openings on both sides of the symmetrical base, and the two aeration pipes are roughly in the same transverse direction.

[0026] The outer surface of the base has at least two connecting ports, the axial direction of which is projected on the horizontal plane at an angle of approximately 90 degrees. The two connecting ports with an angle of approximately 90 degrees are used to connect two aeration pipes respectively and can be arranged at the four corners of the bottom of the reaction tank. Figure 1 The structure at the upper left corner has two connecting ports on the right and bottom of the base. An aeration pipe is installed at each of these connecting ports, and the two aeration pipes are roughly at a right angle.

[0027] Base Figure 2 , 3 The vertical direction shown is a cylinder, and multiple communication ports are evenly arranged radially on the outer edge of the cylinder, and a flange is arranged on the upper end face of the cylinder. The base is made of corrosion-resistant metal material or corrosion-resistant plastic material, and multiple holes are evenly arranged radially on the cylinder. A hollow communication port is installed on each hole by screwing or welding, and the part of the hole located inside the cylinder is connected to the opening of the flange. The base can be manufactured by casting the cylinder, flange and hole or machining the flange and hole on the cylindrical blank.

[0028] The bottom surface of the base is formed with a boss, and the center of the boss is formed with a threaded hole, into which the upper end of a support column 10 can be screwed. A disc is formed at the lower end of each support column to increase the support stability, and the support columns can be of different heights to meet the requirements of the installation height of the bottom of the reaction tank.

[0029] like Figure 1-5 As shown, the number of the connecting ports is 4, 8 or 12. The number of connecting ports of the base can be selected according to the usage location, for example: Figure 1 In the embodiment, bases with 8 connecting ports are selected at the four corners, sides and other places; Figure 5 In the embodiment, the four corners, the sides and the middle partition all use bases with four connecting ports, while the bases used in the rest of the places have 12 connecting ports.

[0031] The structure of the above-mentioned fixing sleeve allows it to slide left or right on the pipe body to the connecting head, and then the internal threads on the left and right sides of the fixing sleeve can be put on the connecting port on the same side, and then matched with the connecting heads with the same structure at both ends of the pipe body, so that no matter which end of the pipe body can be connected to the connecting port, which improves the convenience during on-site construction.

[0032] The end of the connector on one side of the tube body located outside the tube body can be detachably connected to the connecting port provided on the base by screwing or embedding. Figure 4 As shown, the cross-sectional shape of the end 17 of the connector is square, and the connecting port is correspondingly set to a square inner hole end (the rest of the inner hole can be round), so that the square connector is embedded in the square inner hole. After the connector is connected to the connecting port, the convex ring 9 presses a sealing gasket 18 sleeved on the end of the connector against the end face of the end of the connecting port. After the convex ring is pressed against the end face of the connecting port, the fixing sleeve is rotated and the internal thread on the same side of the fixing sleeve is screwed on the external thread on the outer edge of the connecting port. After the fixing sleeve is tightened, the pipe body and the connecting port can be detachably fixedly connected. The connector on the other side of the pipe body is provided with a plug 5 for sealing. The above-mentioned connector embedding part, the fixing sleeve screwing part and the plug sealing part can be coated with glue or other acceptable auxiliary sealing methods to further improve the sealing or stability of the connection.

Similarly, a clamp 11 is mounted on one end of the aeration pipe body where the plug is installed. The clamp is divided into two parts. One part is an arc structure with bent edges on both sides, and the other part has a protrusion 15 at the bottom in addition to these structures. The protrusion is used to screw the support column 10. The two clamps are fixed to each other by bolts 13 on the installation edges that are crimped together.
