[0002] During the sewage treatment process, certain methods and equipment are used to force air into the sewage, so that the sewage in the pool comes into contact with the air and is oxygenated, and the liquid is stirred to accelerate the transfer of oxygen in the air to the liquid, preventing suspended objects in the pool from sinking, and strengthening the contact between organic matter in the pool and microorganisms and dissolved oxygen, thereby oxidizing and decomposing the organic matter in the sewage. This process of forcing oxygen into the sewage is called aeration.

[0003] The existing aeration device is mainly composed of an air pump and an aeration tube. Usually, the aeration tube is directly fixed to the bottom of the sewage pool. The bubbles generated by aeration come into contact with the sewage during the process of floating upward, increasing the oxygen content in the sewage. However, the contact area between the bubbles and the sewage during the floating process is relatively small, and the aeration effect needs to be further improved. Secondly, when the parts of the aeration tube assembly are damaged or the micropores on the aeration tube are blocked, it is necessary to empty the sewage in the sewage pool and then enter the sewage pool to disassemble and maintain the aeration tube assembly, which is troublesome during use. Therefore, the utility model proposes an aeration device for sewage treatment. Utility Model Content

[0024] The aeration assembly 4 includes a main air pipe 41 fixed to and connected with the pipe sleeve 3 and a plurality of branch pipes 42. External thread heads 43 are fixed to the outer wall of the main air pipe 41 and one end of the branch pipe 42. The other end of the branch pipe 42 is provided with internal threads matching the external thread heads 43. An aeration head 45 is fixed to the top of each branch pipe 42, and micropores are opened at the top of the aeration head 45.

[0025] The branch pipe 42 can be screwed to the external thread head 43 on the outer wall of the main air pipe 41 through the internal thread, so as to realize the connection between the branch pipe 42 and the main air pipe 41. Secondly, the two branch pipes 42 can also be connected by screwing one branch pipe 42 to the external thread head 43 at one end of another branch pipe 42. Therefore, when the device is actually installed, the branch pipes 42 of appropriate length can be flexibly spliced ​​according to the size of the sewage pool. When air is pumped into the main air pipe 41, the air is discharged along the micropores on the multiple aeration heads 45 at the top of the branch pipe 42 to realize the aeration function.

[0026] The air outlet of the air pump 8 is fixedly connected with a hose 9, and the other end of the hose 9 is communicated with the pipe sleeve 3. After the air pump 8 is started, air can be pumped into the main air pipe 41 of the aeration assembly 4 through the hose 9.

[0027] An end cover 44 is provided to match the external thread head 43 , and the end cover 44 is rotationally connected to the external thread head 43 through threads.

[0028] After the multiple branch pipes 42 are connected, the end cap 44 can be screwed onto the external thread head 43 on the end of the branch pipe 42 to seal the end of the branch pipe 42.

[0029] A protective cover 46 is rotatably connected to the top surface of the aeration head 45 through a thread, and a partition net 47 is fixedly connected to the middle of the protective cover 46 .

When the device is working normally, start the air pump 8, and pump air into the main air pipe 41 of the aeration component 4 through the air pump 8, and the air is discharged from the aeration head 45 at the top of the branch pipe 42 to achieve aeration. In this process, the motor 63 can be started to drive the screw 62 to rotate back and forth, so that the screw 62 can be used to drive the lifting plate 61 and the U-shaped rod 2 to move up and down, so that the aeration component 4 moves up and down in the sewage pool, increasing the probability of the bubbles generated by aeration contacting the sewage and improving the aeration effect. If the partition 47 of the aeration component 4 is blocked or the branch pipe 42 is damaged, the aeration component 4 can be raised above the sewage surface, and then the branch pipe 42 can be disassembled or the partition 47 can be cleaned.
