During the reciprocating movement of the aeration tube, the meshing of the gear and the rack will drive the aeration tube to rotate back and forth. The rotational movement is softer than aeration in a fixed direction, which can avoid local impact on the water body caused by concentrated emission of bubbles.

In particular, the vortex formed during rotation can further stir the water body and promote oxygen dissolution. Through the combination of the two, oxygen can reach almost every corner of the water body. Compared with static aeration or single dynamic aeration, this combination can utilize oxygen more efficiently and improve the aeration effect of sewage. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The aeration mechanism 2 includes an air pump 201, one end of the air pump 201 is connected to an air delivery pipe 202, the air delivery pipe 202 runs through the aeration tank 1, a plurality of aeration pipes 203 are arranged on one side of the air delivery pipe 202, the surface of the aeration pipe 203 is connected to an aeration plate 204, two protective shells 205 are fixed to the bottom of the inner wall of the aeration tank 1, two slide grooves are provided on the surface of the protective shell 205, a sliding plate 206 is slidably connected to the surface of the slide groove, the aeration pipe 203 runs through the sliding plate 206, the aeration pipe 203 is rotatably connected to the surface of the sliding plate 206, the surface of the air delivery pipe 202 is connected to a rotary joint 207, and the surface of the aeration pipe 203 is provided with a rotary joint 207 near the rotary joint 207. A one-way valve is installed, the air inlet end of the rotary joint 207 is connected to the air pipe 202, the air outlet end of the rotary joint 207 is connected to the aeration pipe 203, one end of the aeration pipe 203 is rotatably connected to a support plate 208, a rack 209 is arranged inside the protective shell 205, the rack 209 is fixed to the bottom of the inner wall of the aeration tank 1, a gear 210 is fixed on the surface of the aeration pipe 203, the gear 210 is meshed with the rack 209, a bellows 211 is installed on the surface of the air pipe 202, the left side of the surface of the air pipe 202 is arranged in sections, the exhaust end of the left air pipe 202 is connected to the air inlet end of the bellows 211, and the air inlet end of the right air pipe 202 is connected to the exhaust end of the bellows 211;

[0027] The air pump 201 can input compressed air into the aeration pipe 203 through the air pipe 202 and the rotary joint 207, so that the compressed air can be blown upward through the aeration plate 204, so that the aeration plate 204 can aerate the sewage. When it is necessary to expand the aeration range and improve the aeration effect, the aeration pipes 203 are reciprocated by the driving mechanism 3, and the aeration pipes 203 are reciprocated along a certain path in the water body, so that they can cover the entire treatment area more comprehensively, avoiding the situation where a local area is over-aerated and other areas are insufficient, thereby achieving a more uniform oxygen distribution. At the same time, when the aeration pipes 203 reciprocate, the aeration pipes 203 can be reciprocated to form a certain aeration pattern. During the movement, the meshing of the gear 210 and the rack 209 will drive the aeration tube 203 to rotate back and forth. The rotational movement is softer than aeration in a fixed direction, which can avoid local impact on the water body caused by concentrated emission of bubbles. At the same time, the surface area of ​​contact between the gas and the water body will also increase, making the oxygen transfer more efficient. In particular, the vortex formed during rotation can further stir the water body and promote oxygen dissolution. Through the combination of the two, oxygen can reach almost every corner of the water body. Compared with static aeration or single dynamic aeration, this combination can more efficiently utilize oxygen and improve the aeration effect of sewage.

[0028] Further, the driving mechanism 3 includes a rotating shaft 301, and there are two rotating shafts 301. The rotating shaft 301 passes through the aeration tank 1, and the rotating shaft 301 is rotatably connected to the aeration tank 1 at the point where it passes through. A mounting shell 302 is fixed to both the front and rear sides of the inner wall of the aeration tank 1. The rotating shaft 301 passes through the mounting shell 302, and a reciprocating screw rod 303 is fixed to one end of the rotating shaft 301. One end of the reciprocating screw rod 303 is rotatably connected to the inner wall of the mounting shell 302. A threaded sleeve 304 is threadedly connected to the surface of the reciprocating screw rod 303. A movable groove is provided at the bottom of the mounting shell 302. The threaded sleeve 304 is slidably connected to the surface of the movable groove. A connecting sleeve 305 is fixed to the bottom of the rear threaded sleeve 304. The connecting sleeve 305 is fixed to the surface of the gas transmission pipe 202, and the bottom of the front threaded sleeve 304 is fixedly connected to the top of the support plate 208.

[0029] The rotating shaft 301 can drive the reciprocating screw rod 303 to rotate. When the reciprocating screw rod 303 rotates, the threaded sleeve 304 will be affected by the thread and start to reciprocate on the surface of the reciprocating screw rod 303, and the rear threaded sleeve 304 will drive the gas pipe 202 to move synchronously through the connecting sleeve 305, so that the bellows 211 can be extended and retracted. At the same time, the front threaded sleeve 304 can drive the support plate 208 to move, and then the support plate 208 and the gas pipe 202 can drive the front and rear sides of the aeration pipe 203 to move together, so that the aeration pipe 203 drives the sliding plate 206 to slide inside the slide groove, so that the aeration pipe 203 can achieve a left and right reciprocating movement effect.

[0030] Furthermore, a reduction motor 307 is fixed on the surface of the aeration tank 1, and the output shaft of the reduction motor 307 is fixedly connected to one end of the front rotating shaft 301. A transmission wheel 306 is fixed on the surface of the rotating shaft 301, and the transmission wheels 306 on both sides are connected by belt transmission;

[0031] When the reduction motor 307 is started, it will drive the front shaft 301 to rotate. At the same time, the front transmission wheel 306 will also drive the rear shaft 301 to rotate synchronously with the rear transmission wheel 306 through the belt, thereby ensuring that the shafts 301 on both sides can drive the reciprocating screw rod 303 to rotate synchronously.

[0032] Further, the transmission wheel 306 is a timing pulley, and the transmission belts of the transmission wheels 306 on the front and rear sides are timing belts;

[0033] The combination of the timing belt and the timing pulley has greater friction, thereby ensuring that the rotating shafts 301 on both sides can rotate synchronously.

[0034] Furthermore, the surface of the aeration tank 1 is connected to two second drain valves 6;

[0035] Opening the second sewage valve 6 can allow the sewage that has penetrated into one side of the protective shell 205 to be discharged normally, thereby preventing the sewage from accumulating in the area below the separation plate 4 .

[0037] When the sliding plate 206 moves, the first accordion cover 213 can be extended and retracted, and when the threaded sleeve 304 moves, the second accordion cover 309 can also be extended and retracted together, so that the first accordion cover 213 can cover the slide groove, and the second accordion cover 309 can cover the movable groove, so that sewage is not easy to enter the protective shell 205 and the installation shell 302.

[0038] Furthermore, a plurality of movable wheels 212 are fixed to the bottom of the support plate 208, and the movable wheels 212 are slidably connected to the bottom of the inner wall of the aeration tank 1;

[0039] The movable wheel 212 can provide a supporting effect for the support plate 208 to prevent the support plate 208 from tilting.

[0040] Furthermore, the sliding plate 206 is arranged in an I-shaped structure, and the surface of the sliding plate 206 is slidably connected to the surface of the protective shell 205;

[0041] The I-shaped structure can make the sliding plate 206 fit the surface of the protective shell 205, so that the sliding plate 206 can obtain the upper and lower limit effect in the slide groove on the surface of the protective shell 205, preventing the sliding plate 206 from escaping from the slide groove.

[0042] Furthermore, a limit plate 308 is fixed on the surface of the reciprocating screw rod 303;

[0043] The limiting plate 308 can limit the movable distance of the threaded sleeve 304 to ensure that the threaded sleeve 304 does not move beyond the thread, thereby preventing the threaded sleeve 304 from detaching from the surface of the reciprocating screw rod 303 .

[0044] Furthermore, the support plate 208, the gear 210, the reciprocating screw 303 and the threaded sleeve 304 are all made of stainless steel;

[0045] Stainless steel can effectively resist corrosion from most chemical media such as air, water, acid, alkali, salt, etc. It can also have a good service life when used in water, thereby ensuring that multiple components are not easily damaged by corrosion.
