[0002] Aeration in a sewage treatment tank is a key link, which is crucial for improving the sewage treatment effect; through aeration, the efficiency of sewage treatment can be improved, the content of organic matter and suspended solids in the effluent can be reduced, and the discharge standard can be achieved.

[0003] An aeration pipe is installed in the aeration tank. The existing aeration pipes are directly fixed in the aeration tank. When a problem occurs, the water in the entire aeration tank needs to be drained, and then the staff can go down into the tank for maintenance, which is extremely inconvenient. Content of the Utility Model

[0021] See also Figures 1-4 A sewage treatment tank aeration structure includes a tank body 1, a column 2 is fixedly installed on the inner bottom wall of the tank body 1, a mounting seat 3 is fixedly installed on the column 2 and the top of the tank body 1, a sleeve 4 is sleeved on the outer side of the column 2, a guide rail seat 5 is embedded on the outer side of the column 2, a slider 6 is fixedly installed on the inner wall of the sleeve 4, and the slider 6 is installed in the inside of the guide rail seat 5. The sleeve 4 is connected to the outer side of the column 2 by sliding up and down through the guide rail seat 5 and the slider 6, and it can ensure that the sleeve 4 will not rotate on the outer side of the column 2.

[0022] See also Figures 1-4 The outer wall of the sleeve 4 is fixedly mounted with an extension pipe 7, and three concentric ring pipes 8 are fixedly mounted on the outer side of the extension pipe 7. The diameters of the three ring pipes 8 gradually decrease from the outside to the inside, and the three ring pipes 8 are arranged at equal intervals. The ring pipe 8 is connected to the extension pipe 7; the top of the ring pipe 8 is threadedly connected with an aeration plate 9, and the bottom of the ring pipe 8 is fixedly mounted with a base 10. When the ring pipe 8 is placed at the bottom of the tank body 1, the base 10 is used to isolate the ring pipe 8 from contacting the bottom of the tank body 1.

[0023] See also Figures 1-4 A hose 11 is detachably mounted on the top of the coil tube 8 through a flange. When the coil tube 8 moves upward, the hose 11 can be bent into a U shape. A control valve 12 is detachably mounted on the top of the hose 11 through a flange. An exhaust end of a high-pressure blower 13 is detachably mounted on the other side of the control valve 12 through a flange. The high-pressure blower 13 is fixedly mounted to the outer wall of the pool body 1 through a support 14.

[0024] By operating the high-pressure blower 13 , high-pressure air enters the interior of the coil tube 8 through the hose 11 , and finally the air is ejected from the aeration disk 9 .

[0025] See also Figures 4-6, inside the mounting base 3 on the top of the vertical column 2, two double-axial drive motors 15 are fixedly installed. On both output ends of the drive motor 15, drive shafts 16 are fixedly installed. One end of the drive shaft 16 far away from the drive motor 15 is rotatably installed inside the mounting base 3. On the outer side of one of the drive shafts 16, a drive wheel 17 is fixedly installed. On the outer side of the other drive shaft 16, a gear 18 is fixedly installed. A vertical rod 19 is inserted between the gear 18 and the drive wheel 17. On the side surface of the vertical rod 19, a tooth groove 20 corresponding to the gear 18 is provided.

[0026] By driving the drive shaft 16 to rotate through the drive motor 15, the drive shaft 16 controls the drive wheel 17 and the gear 18 to rotate, and then the vertical rod 19 is lifted or lowered.

[0027] Please refer to Figures 4-6 , at the bottom of the vertical rod 19, a hanging ring 21 is fixedly installed. The hanging ring 21 is connected to the ring pipe 8 through a lifting lug 22. On the outer side of the drive shaft 16 and between the outer sides of two adjacent mounting bases 3, a housing 23 is detachably installed, which is used to protect the drive shaft 16, the drive wheel 17 and the gear 18.

[0028] Working principle: When in use, the operation of the high-pressure blower 13 generates air. The air enters the inside of the ring pipe 8 and the extension pipe 7 through the hose 11, and finally the air is ejected from the aeration disc 9, increasing the contact between the sewage and the air;

[0029] When repairing the aeration disc 9 without emptying the sewage, the two double-axial drive motors 15 drive the two drive shafts 16 to rotate synchronously. Then the gear 18 drives the vertical rod 19 to move upward, and the drive wheel 17 assists the vertical rod 19 to move upward. As the vertical rod 19 moves upward, the entire ring pipe 8 follows and moves upward. The ring pipe 8 moves upward on the outside of the vertical column 2 through the sleeve 4. There is a slider 6 on the inner side of the sleeve 4, and the slider 6 slides in the guide rail seat 5, which can ensure that the ring pipe 8 does not rotate during the upward movement;

[0030] As the ring pipe 8 moves upward, the hose 11 will also bend into a U shape accordingly, so as not to affect the upward movement of the ring pipe 8; when the ring pipe 8 and the aeration disc 9 move upward to the top of the pool body 1 and then stop, it is convenient for personnel to disassemble, install or replace and repair the aeration disc 9.

[0031] On the contrary, by driving the drive shaft 16 to rotate synchronously in reverse through the double-axial drive motor 15, then the drive wheel 17 and the gear 18 send the vertical rod 19 downward until the ring pipe 8 falls on the inner bottom wall of the pool body 1. During this process, the purpose of replacing and repairing the aeration disc 9 can be achieved without discharging the sewage in the pool body 1.
