[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0025] This utility model provides an anti-clogging aeration device for sewage treatment, as described below. Figures 1 to 4 Please provide a detailed explanation.

[0026] A clog-resistant aeration device for sewage treatment includes a sewage tank 1. An aeration pipe 2 is installed through the side wall of the sewage tank 1. An aeration head 3 is installed at one end of the aeration pipe 2 inserted into the sewage tank 1. The aeration head 3 is hollow inside. A plurality of aeration holes 31 are provided at the end of the aeration head 3 away from the aeration pipe. A unclogging rod 32 is installed in each aeration hole 31. A synchronization control mechanism 4 and an automatic reset mechanism 5 are provided in the aeration head 3 to simultaneously control the synchronous reciprocating movement of all unclogging rods 32.

[0027] This invention adds an aeration head 3 to the end of the aeration pipe 2. A cleaning rod 32 is installed in the aeration hole 31 of the aeration head 3 to clean impurities from the aeration hole 31. A synchronous control mechanism 4 and an automatic reset mechanism 5 control the synchronous movement of all cleaning rods 32 in each aeration hole 31, thereby sealing the aeration hole 31 when not in aeration mode to prevent impurities from entering the aeration head 3. Furthermore, at the end of aeration, the cleaning rod 32 can be inserted into the aeration hole 31 under the action of the automatic reset mechanism 5 to clear the blockage of impurities in the aeration hole 31. When aeration resumes, the gas will blow the remaining impurities in the aeration head 3 out of the aeration head 3.

[0028] In some embodiments, the synchronization control mechanism 4 includes a connecting plate 41 disposed at the end of the aeration hole 31 opposite to the aeration pipe. The connecting plate 41 is fixedly connected to each unclogging rod 32, thereby enabling the movement of all unclogging rods 32 to be controlled by controlling the connecting plate 41. A drive rod 42 is disposed on the connecting plate 41. The drive rod 42 passes through any aeration hole 31 and is fixedly connected to a control plate 43. The control plate 43 is connected to the automatic reset mechanism 5. The automatic reset mechanism 5 can achieve synchronous control of all unclogging rods 32 by controlling the control plate 43.

[0029] In some embodiments, the automatic reset mechanism 5 includes two fixing frames 51 symmetrically fixedly disposed on the inner wall of the aeration head 3. The fixing frames 51 are disposed between the aeration hole 31 and the control plate 43. A collar 52 is provided at the end of the fixing frame 51. A support rod 53 is slidably disposed inside the collar 52. A locking plate 54 is provided at one end of the support rod 53 facing the control plate 43. A spring 55 is sleeved on the support rod 53. The spring 55 is disposed between the fixing frame 51 and the locking plate 54.

[0030] When aeration is performed, gas enters the aeration head 3 along the aeration pipe, the internal air pressure increases, and the gas can push the unblocking rod 32 in each aeration hole 31 out of the aeration hole 31, thus starting the aeration operation. At this time, the spring 55 is compressed and the support rod 53 slides towards the aeration hole 31.

[0031] When the aeration operation is completed, the unblocking rod 32 loses the thrust support generated by the high air pressure, and the spring 55 will return to its original deformation, thereby pushing the control plate 43 to move upward. The upward movement of the control plate 43 drives the connecting plate 41 to move upward through the drive rod 42, thereby controlling the synchronous reset of each unblocking rod 32 on the connecting plate 41. The unblocking rod 32 will be inserted into the aeration hole 31 again. At this time, if there is a blockage in the aeration hole 31, the unblocking rod 32 will push the blockage impurities into the aeration head 3. When aeration occurs again, the violent impact of the high-pressure gas in the aeration head 3 will cause the impurities in the aeration head 3 to be flushed out of the aeration hole 31.

[0032] In some embodiments, a limiting plate 56 is provided at the end of the support rod 53 facing the aeration hole 31. The limiting plate 56 can prevent the support rod 53 from disengaging from the collar 52.

[0033] In some embodiments, the aeration head 3 is provided with an anti-backflow mechanism 6, which includes an isolation ring 61 disposed above the control plate 43. The isolation ring 61 has a central annular hole 62, and the control plate 43 abuts against the bottom wall of the isolation ring 61. The isolation ring 61 divides the space in the aeration head 3 into two independent spaces: a first space communicating with the aeration pipe 2 and a second space communicating with the aeration hole 31. In the non-aeration state, the control plate 43 abuts against the bottom wall of the isolation ring 61, thereby preventing impurities or wastewater in the second space from entering the first space and contacting the aeration pipe 2, thus protecting the aeration pipe and significantly reducing the possibility of blockage.

[0034] In some embodiments, the control plate 43 is configured as a sealing plate. The sealing plate ensures a tight seal between the control plate 43 and the isolation ring 61.

[0035] In some embodiments, a sealing gasket 63 is provided on the control plate 43 corresponding to the annular hole 62, and the sealing gasket 63 is slidably connected to the sidewall of the annular hole 62. The sealing gasket 63 can effectively increase the sealing area, thereby further ensuring the sealing performance between the control plate 43 and the isolation ring 61.

[0036] In some embodiments, the normal length of the spring 55 is not less than the height between the bottom wall of the control plate 43 and the top wall of the fixing frame 51. This ensures that the control plate 43 is supported by a force perpendicular to the end face of the isolation ring 61, thereby allowing the control plate 43 to fit against the bottom end face of the isolation ring 61 and ensuring the sealing between the isolation ring 61 and the control plate 43.

[0037] In some embodiments, the drive rod 42 is positioned at the center of the connecting plate 41, and the unblocking rods 32 are symmetrically arranged on both sides of the drive rod 42. The aeration holes 31 are positioned in match with the unblocking rods 32. Positioning the drive rod 42 at the center ensures that the force exerted by the drive rod 42 on the connecting plate 41 and the fixing rod is more uniform, thereby guaranteeing that the springs 55 on both sides of the automatic reset mechanism 5 exert the same force, and preventing uneven wear of the springs 55 due to long-term imbalance of force.

[0038] In some embodiments, an aeration pump is installed on the aeration pipe 2 located outside the sewage tank 1. Positioning the aeration pump outside the sewage tank 1 facilitates operation and maintenance by staff.
