Because the outlet pipe is connected with the connecting groove in the aeration cover through a through groove, the gas is discharged driven by the liquid level difference. After the gas is discharged, the bottom liquid fills upward and enters the aeration pipe through the air inlet groove to fill the pipe, and the exhaust stops. Then, with the continuous entry of gas, the liquid is discharged again, and large bubbles and large liquid blocks appear alternately.

[0016] 4. The present invention provides a cleaning mechanism, and by pulling the handle, the cleaning shell can slide out of the fixed shell, and then the dirt in the cleaning shell can be cleaned. After the cleaning of the cleaning shell is completed, the cleaning shell is slid back into the frame along the positioning block, and the two sets of sealing members on the cleaning shell need to be slid into the interface between the frame and the fixed shell to prevent leakage, so that the inside of the aeration mechanism can be quickly cleaned and the service life of the aeration tank is increased.

[0017] 5. The present invention provides an adjustment mechanism. It only needs to pull the pull plate to drive the adjustment plate to slide together. The adjustment plate is at the bottom of the air outlet square groove.

A water inlet pipe 9 is fixedly connected to the inner wall of the fixed shell 8. The partition plate 10 divides the fixed shell 8 into six groups of cavities, and each group of cavities is provided with a water inlet pipe 9, and the water inlet pipe 9 is linearly arrayed along the outer wall of the fixed shell 8.

The outer wall of the expansion tube 35 is slidably connected to the inner wall of the sliding ring 72. Because the diameter of the expansion tube 35 is smaller than the diameter of the expansion nozzle 36, when the bubble moves to the expansion nozzle 36, it will move out of the expansion nozzle 36 along the outer wall of the expansion nozzle 36, thereby changing the shape of the bubble.

[0036] Working principle:

[0037] When in use, firstly, the air inlet pipes 2 on both sides of the frame 1 need to be connected to the external air supply pipes, so that the air in the external air supply pipes can enter the frame 1 through the air inlet pipes 2 on both sides, and then the frame 1 is placed as a whole in the sewage, so that the sewage immerses the frame 1, and then the sewage enters the fixed shell 8 through the water inlet pipe 9 on the back side of the frame 1, and the fixed shell 8 is divided into six groups of small cavities by the partition plate 10 in the fixed shell 8, and the structures in the six groups of small cavities are the same, so the sewage entering the fixed shell 8 is filled into the aeration mechanism 4, and the air in the air supply pipe enters the frame 1 and fills the interior of the frame 1, and then passes through the air outlet square pipe 4 at the bottom of the fixed shell 8. 4 enters the small cavity and mixes with the sewage to achieve aeration. The air coming out of the aeration mechanism 4 can be expanded by the expansion mechanism 3 on the top of the frame 1, so as to change the shape of the bubble. When the shape of the bubble needs to be changed, it is only necessary to replace the expansion nozzle 36 in the expansion mechanism 3 through the quick connection mechanism 7. After long-term use, dirt will accumulate in the aeration mechanism 4. At this time, the dirt in the aeration mechanism 4 can be removed by the cleaning mechanism 5, so as to extend the service life of the aeration mechanism 4. During the use of the aeration tank, the air intake of the aeration mechanism 4 can be changed by the adjustment mechanism 6, so as to change the amount of bubbles generated in the small cavity.

[0038] Sewage also enters the small cavity along the water inlet pipe 9 and fills the inside of the small cavity, so that the aeration pipe 43 is filled with sewage. Then the outer wall air supply pipe is opened to allow the air in the air outlet square pipe 44 to be discharged into the small cavity through the air outlet holes 45 on both sides. With the continuous air intake of the air outlet square pipe 44, the gas presses out the liquid in the aeration pipe 43 and the air outlet pipe 49 to form an air cavity. The liquid level in the aeration pipe 43 is reduced and the aeration pipe 43 cannot be filled. Because the air outlet pipe 49 is connected to the connecting groove 46 in the aeration cover 41 through the through hole 48, the gas is discharged driven by the liquid level difference. After the gas is discharged, the bottom liquid fills upward and enters the aeration pipe 43 through the air inlet groove 47 to fill the pipe. The exhaust stops, and then the liquid is discharged again under the continuous entry of gas. This cycle is repeated to achieve pulse aeration.

[0039] The gas discharged from the aeration mechanism 4 can be discharged through the expansion mechanism 3. When the gas moves to the expansion mechanism 3, the gas first enters the expansion pipe 35, and then moves to the expansion nozzle 36 through the expansion pipe 35. Because the diameter of the expansion nozzle 36 is larger than the diameter of the expansion pipe 35, when the air moves to the expansion nozzle 36, it moves out along the outer wall of the expansion nozzle 36, thereby changing the shape of the gas in the water. The expansion mechanism 3 can be taken out from the fixed frame 31. When the expansion work is not needed, it is only necessary to take out the plug 32 from the fixed frame 31, and then slide out the limit block 33, and then the limit plate 34 connected to the expansion pipe 35 can be taken out together.

[0040] When the bubble shape needs to be changed during the expansion work, the slip ring 72 only needs to be rotated to slide the slider 75 on the slip ring 72 out of the limit groove 71 on the expansion nozzle 36 to release the lock of the expansion nozzle 36, and then the new expansion nozzle 36 is reinserted into the expansion tube 35, and then the slip ring 72 is slid upward along the limit groove 71. After the slider 75 slides to the top of the limit groove 71, the slip ring 72 is rotated again to re-lock the position of the slip ring 72, and the limit ring 74 on the slip ring 72 slides on the expansion tube 35 through the ring groove 73 to limit the position of the slip ring 72.

[0041] When it is necessary to clean the aeration mechanism 4, first take the aeration tank out of the sewage, then stop supplying air to the aeration tank, and then pull the handle 53 to slide the cleaning shell 51 out of the fixed shell 8, and then clean the dirt in the cleaning shell 51. It should be noted that when cleaning the cleaning shell 51, a high-pressure water gun can be used to flush the sewage outlet 410 at the bottom of the aeration pipe 43 to further clean the aeration mechanism 4. After the cleaning of the cleaning shell 51 is completed, the cleaning shell 51 is slid back into the frame 1 along the positioning block 54, and the two sets of sealing members 52 on the cleaning shell 51 need to be slid into the interface between the frame 1 and the fixed shell 8 to prevent leakage.

[0042] Before use, the aeration tank can change the air intake of the aeration mechanism 4 by changing the adjustment mechanism 6 below the aeration mechanism 4, so that fixed-point aeration work can be achieved. It only needs to pull the pull plate 61, and the adjustment plate 64 is driven to slide together through the pull plate 61. Because the adjustment plate 64 is at the bottom of the air outlet square groove 62, when the air outlet square groove 62 lacks the obstruction of the adjustment plate 64, the air at the bottom of the cleaning shell 51 can enter the cavity through the air outlet square groove 62, thereby increasing the air intake of the cavity and further increasing the aeration amount of the aeration mechanism 4.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
