[0002] During the sewage treatment process, aeration treatment is usually required. A plurality of microporous aerators are installed at the bottom of the sewage tank, and the plurality of microporous aerators are connected by an air delivery pipeline. Then, compressed air flows into the microporous aerators through the air delivery pipeline and forms fine bubbles flowing into the sewage to achieve the purpose of aeration. Due to the fixed size of the microporous aerators, the aeration range of the microporous aerators is small. Therefore, for a sewage tank with a large area, it is necessary to increase the layout density of the microporous aerators, and the workload of maintaining the microporous aerators in the later stage increases. Therefore, it is necessary to design a water treatment aeration dispersion device with an enlarged aeration range. Content of the Utility Model

[0003] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a water treatment aeration dispersion device to solve the problems raised in the above background technique. The utility model enlarges the aeration range and reduces the layout density of the microporous aerators.

[0004] To achieve the above purpose, the utility model is realized through the following technical solutions: A water treatment aeration dispersion device includes a pipe joint for installing on an air delivery pipeline. The middle position of the outer surface of the pipe joint is provided with a lower straight pipe communicated with the pipe joint. The upper end of the lower straight pipe is provided with a detachable upper straight pipe. The upper end of the upper straight pipe is provided with a microporous aerator. A gas baffle is arranged directly above the microporous aerator. The inner diameter of the gas baffle gradually increases from bottom to top. The cross-section of the gas baffle is stepped. A plurality of ventilation holes are evenly arranged on the horizontal part surface of the gas baffle. Two support plates are installed between the gas baffle and the pipe joint.

[0005] Furthermore, the outer surface of the lower end of the upper straight pipe is sleeved with an upper connecting ring connected and fixed to the upper straight pipe. The outer surface of the upper end of the lower straight pipe is sleeved with a lower connecting ring connected and fixed to the lower straight pipe. The upper connecting ring is connected and fixed to the lower connecting ring by two screws.

[0006] Furthermore, two upper round holes are symmetrically arranged on the upper surface of the upper connecting ring. Two lower round holes aligned with the upper round holes are symmetrically arranged on the upper surface of the lower connecting ring. Two positioning seats are clamped on the pipe joint. The two positioning seats are symmetrically arranged with respect to the lower straight pipe. The positioning seats are attached to the lower connecting ring. A screw hole aligned with the lower round hole is arranged on the upper surface of the positioning seat. One end of the screw sequentially penetrates through the upper round hole, the lower round hole and is threadedly connected in the screw hole. One end of the support plate away from the gas baffle is connected and fixed to the positioning seat.

[0007] Further, a second arc-shaped groove is machined on the surface of the positioning seat facing the pipe joint, the pipe joint is inserted into the second arc-shaped groove, a first arc-shaped groove is machined on the surface of the positioning seat facing the lower straight pipe, and the lower straight pipe is inserted into the first arc-shaped groove.

[0008] Further, the support plate is of an L-shaped structure, a slot is opened at the position where the positioning seat installs the support plate, one end of the support plate away from the air baffle is fixed in the slot, a connecting plate is fixedly connected to the end of the support plate away from the positioning seat, and the connecting plate is fixedly connected to the air baffle.

[0009] Further, a first flange is installed at one end of the pipe joint, and a second flange is installed at the end of the pipe joint away from the first flange.

[0010] Advantages of the present utility model:

[0011] 1. An air baffle with a stepped cross-section is arranged directly above the microporous aerator, and a plurality of ventilation holes are opened on the horizontal surface of the air baffle. Further, after the compressed air flows out through the microporous aerator, it is blocked by the air baffle. Part of the bubbles pass through the air baffle through the ventilation holes, and part of the bubbles pass through from the outer edge of the air baffle after being blocked by the air baffle, thereby increasing the aeration range, reducing the layout density of the microporous aerators, and being beneficial to reducing the workload of maintaining the microporous aerators in the later stage.

[0012] 2. When connecting the upper straight pipe and the lower straight pipe with screws, a clamping relationship is formed between the positioning seat, the pipe joint and the lower straight pipe. At this time, the positioning seat is in contact with the lower connecting ring. Further, the pipe joint, the lower straight pipe and the lower connecting ring jointly limit the position of the positioning seat, so that the screws pass through the upper round hole and the lower round hole in sequence and are threadedly connected to the screw holes on the positioning seat, realizing the fixation of the relative positions of the positioning seat, the lower straight pipe, the upper straight pipe and the pipe joint, without using a plurality of screws to connect the upper straight pipe and the lower straight pipe and then using a plurality of screws to limit the position of the air baffle, thus reducing the usage amount of screws.

By setting a gas baffle 6 with a stepped cross-section directly above the microporous aerator 5 and opening a plurality of ventilation holes 7 on the horizontal surface of the gas baffle 6, when the compressed air flows out through the microporous aerator 5, it is blocked by the gas baffle 6. Part of the bubbles pass through the gas baffle 6 through the ventilation holes 7, and part of the bubbles pass through from the outer edge of the gas baffle 6 after being blocked by the gas baffle 6, thereby increasing the aeration range, reducing the layout density of the microporous aerator 5, and being beneficial to reducing the workload of maintaining the microporous aerator 5 in the later stage.

[0023] Refer to Figures 1 - 5, there are two support plates 4 installed between the air baffle 6 and the pipe joint 1. The support plate 4 is of an L-shaped structure. Slots are provided at the position where the positioning seat 2 installs the support plate 4, so that one end of the support plate 4 away from the air baffle 6 is fixed in the slot, improving the connection stability between the support plate 4 and the positioning seat 2.

The outer surface of the lower end of the upper straight pipe 10 is sleeved with an upper connecting ring 18 connected and fixed with the upper straight pipe 10. The outer surface of the upper end of the lower straight pipe 11 is sleeved with a lower connecting ring 12 connected and fixed with the lower straight pipe 11. Two upper round holes 19 are symmetrically provided on the upper surface of the upper connecting ring 18.

The surface of the positioning seat 2 facing the lower straight pipe 11 is processed with a first arc groove 16, and the lower straight pipe 11 is inserted into the first arc groove 16. When connecting the upper straight pipe 10 and the lower straight pipe 11 with the screw 9, a clamping relationship is formed between the positioning seat 2, the pipe joint 1 and the lower straight pipe 11. At this time, the positioning seat 2 is in contact with the lower connecting ring 12. Furthermore, the pipe joint 1, the lower straight pipe 11 and the lower connecting ring 12 jointly limit the position of the positioning seat 2, so that the screw 9 sequentially passes through the upper round hole 19, the lower round hole 13 and is threadedly connected in the screw hole 15 on the positioning seat 2, realizing the fixation of the relative positions of the positioning seat 2, the lower straight pipe 11, the upper straight pipe 10 and the pipe joint 1.
