Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, and in particular to an aeration device for wastewater treatment. Background Technology

[0002] Currently, Chinese utility model patent CN213707859U discloses an aeration device for sewage treatment, including an air main pipe. One end of the air main pipe is connected to a filter, and the side of the filter away from the air main pipe is connected to an air pump. An air branch pipe is connected to the lower part of the air main pipe, and an aeration nozzle is installed in the surface of the air branch pipe through a through hole. Each aeration nozzle includes a nozzle tip, an air injection port, a blocking ball, and a connector. This sewage treatment aeration device, by using a blocking ball inside the aeration nozzle, prevents sewage from being back-suctioned into the aeration pipe due to the downward pressure of its own weight after the air pump stops working. The aeration nozzle is positioned at a 45° angle to the vertical direction, and the blocking ball prevents the aeration nozzle from being clogged by sewage impurities, thus improving the aeration effect and allowing for normal operation.

[0003] Existing aeration devices generally have poor aeration effects. The aeration heads are typically fixed to the bottom of the treatment tank, resulting in a fixed aeration area. For larger treatment tanks, this requires covering the entire bottom with aeration heads, significantly increasing treatment costs. Furthermore, the fixed installation creates aeration dead zones, affecting aeration efficiency and making head replacement inconvenient. Aeration heads are usually installed via threads to air pipes, requiring tools for disassembly and reassembly, involving repeated rotation of the aeration head – a cumbersome and inefficient process. To address these problems, we propose an aeration device for wastewater treatment. Utility Model Content

[0004] The purpose of this invention is to provide an aeration device for sewage treatment, which has the advantages of good aeration effect and easy replacement of aeration heads.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an aeration device for sewage treatment, comprising a treatment tank, a fixed shell bolted to the top of the treatment tank, a transmission roller rotatably sleeved on the inner wall of the fixed shell, a driving mechanism disposed between the transmission rollers, a transmission belt fixedly sleeved on the surface of the transmission rollers, a transmission block bolted to the surface of the transmission belt, a first slider rotatably connected to the surface of the transmission block, a transmission plate slidably connected to the surface of the first slider, and the transmission plate slidably connected to the inner wall of the fixed shell, a fixed plate bolted between the surfaces of the transmission plates, and a [missing information - likely a device or mechanism] bolted to the top of the fixed plate. A blower, the output end of which is connected to a fixed pipe, the bottom of which is connected to a diverter pipe, the top of which is connected to a fixed cylinder, an aeration head slidingly fitted onto the inner wall of the fixed cylinder, a rotating cylinder rotatably fitted onto the surface of the fixed cylinder, a connecting rod hinged to the inner wall of the rotating cylinder, a sliding rod hinged to the other end of the connecting rod, the sliding rod slidingly connected to the inner wall of the fixed cylinder, a snap-fit ​​connector bolted to the surface of the sliding rod, a snap-fit ​​groove formed on the surface of the aeration head, the snap-fit ​​connector engaging with the snap-fit ​​groove, a spring positioned between the sliding rod and the inner wall of the fixed cylinder, and a stirring mechanism positioned at the bottom of the fixed plate.

[0006] By adopting the above technical solution, the drive mechanism causes the transmission roller to rotate the transmission belt. The rotation of the transmission belt causes the transmission block to move, which in turn causes the first slider to move the transmission plate back and forth. The back and forth movement of the transmission plate causes the fixed plate to move the aeration head back and forth for aeration. In conjunction with the stirring mechanism, the aeration is stirred and mixed, thereby achieving a good aeration effect, reducing processing costs and improving processing efficiency. By rotating the rotating cylinder, the connecting rod causes the sliding rod to move. The movement of the sliding rod causes the locking joint to move and disengage from the locking groove, allowing the aeration head to be removed and replaced. The replaced aeration head is then installed in the fixed cylinder. Under the action of the spring, the sliding rod causes the locking joint to engage with the locking groove, thus fixing it in place. This method facilitates the replacement of the aeration head, reduces workload, and improves replacement efficiency.

[0008] By adopting the above technical solution and setting a drive mechanism, it is easy to drive and convenient to use.

[0009] The present invention is further configured such that: the stirring mechanism includes a second motor, the second motor is bolted to the top of the fixed plate, the output end of the second motor passes through the fixed plate and is connected to a rotating rod through a coupling, and a stirring rod is bolted to the surface of the rotating rod.

[0010] By adopting the above technical solution and setting up a stirring mechanism, the aeration effect is improved.

[0011] The present invention is further configured such that: a second slider is bolted to the surface of the transmission plate, and a groove is slidably connected to the surface of the second slider, and the groove is formed on the inner wall of the fixed shell.

[0012] By adopting the above technical solution, the transmission plate is prevented from shifting and stability is ensured by setting a second slider and a groove.

[0013] The present invention is further configured such that a protective shell is bolted to the top of the fixing plate, and the blower is located inside the protective shell.

[0014] The above technical solution protects the blower by installing a protective casing.

[0015] The present invention is further configured such that a sealing gasket is provided between the aeration head and the inner wall of the fixed cylinder.

[0016] By adopting the above technical solution, a sealing gasket is installed to prevent air leakage.

[0017] The present invention is further provided that the surface of the rotating cylinder is provided with anti-slip texture.

[0018] By adopting the above technical solution, anti-slip texture is set to prevent hand slippage and facilitate operation.

[0019] The present invention is further configured such that one end of the card connector is wedge-shaped.

[0020] By adopting the above technical solution, one end of the clamp is wedge-shaped, which facilitates the installation of the aeration head.

[0021] In summary, this utility model has the following beneficial effects:

The sliding rod moves the snap-fit ​​connector and disengages from the snap-fit ​​groove, allowing the aeration head to be removed and replaced. The replaced aeration head is then installed in the fixed cylinder. Under the action of the spring, the sliding rod moves the snap-fit ​​connector to engage with the snap-fit ​​groove, thus fixing it in place. This method facilitates the replacement of the aeration head, reduces workload, and improves replacement efficiency. Attached Figure Description

The rotation of the first belt pulley 23 drives the second belt pulley 24 to rotate. The rotation of the second belt pulley 24 drives the transmission roller 3 to rotate. The rotation of the transmission roller 3 drives the transmission belt 5 to rotate. The rotation of the transmission belt 5 drives the transmission block 6 to move. The movement of the transmission block 6 drives the first slider 7 to move the transmission plate 8 back and forth. The back and forth movement of the transmission plate 8 drives the fixed plate 9 to move the aeration head 14 back and forth for aeration, in conjunction with the mixer. The structure 20 is used to stir and mix the aeration to achieve a good aeration effect. Rotating the rotating cylinder 15 causes the connecting rod 33 to move, which in turn causes the sliding rod 16 to move. The sliding rod 16 then causes the snap-fit ​​connector 17 to move and disengage from the snap-fit ​​groove 18. The aeration head 14 is then removed and replaced. The replaced aeration head 14 is then installed in the fixing cylinder 13.
