Description

Technical Field

[0001] The utility model relates to the technical field of water treatment aeration equipment, in particular to a sewage aeration device for water treatment. Background Art

[0002] The sewage purification treatment device is an essential and important equipment in the water treatment project. Sewage purification is a process of purifying sewage to meet the water quality requirements for discharging into a certain water body or reusing it, and it is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering. It has also increasingly entered the daily lives of ordinary people. In the process of sewage purification treatment, an aeration device is generally used. By aerating the sewage through the aeration device, the dissolved oxygen concentration in the water can be maintained, and the biological activity can be enhanced. The existing aeration devices are as follows:

[0003] For example, the patent publication number is CN210595476U, which discloses an aeration tank with a ladder-shaped aeration pipe for sewage treatment, including an aeration tank and an aeration device arranged in the aeration tank. The aeration device includes an aeration motor and a ladder-shaped aeration pipe assembly. The ladder-shaped aeration pipe assembly includes a first aeration main pipe, a second aeration main pipe, and a plurality of aeration branch pipes. The first aeration main pipe and the second aeration main pipe are arranged in parallel. A plurality of first air holes are arranged on the sides of the first aeration main pipe and the second aeration main pipe. The aeration branch pipes are arranged between the first aeration main pipe and the second aeration main pipe. The aeration branch pipes are perpendicular to and communicate with the first aeration main pipe and the second aeration main pipe. A plurality of second air holes are arranged on the side of the aeration branch pipes. The aeration motor is communicated with the first aeration main pipe and the second aeration main pipe through a connecting pipe; the aeration tank with the ladder-shaped aeration pipe for sewage treatment aerates the aeration tank from line to surface, improving the aeration efficiency and the uniformity of aeration.

[0004] In the actual operation of the above-mentioned utility model, the aeration motor is mainly used to transmit air flow into the first aeration main pipe, and the first air holes on the first aeration main pipe are used to aerate the sewage, thereby realizing the purification of the sewage. Although the above-mentioned utility model can realize the aeration of the sewage, since the first aeration main pipe directly discharges gas into the sewage, when the gas enters the sewage, the gas will have an upward buoyancy, causing the gas to quickly float to the water surface. Therefore, the contact time between the gas and the wastewater is short. When the contact time between the gas and the wastewater is short, the dissolution efficiency of the wastewater will be reduced, which will indirectly affect the purification efficiency of the wastewater. Summary of the Invention

[0005] The purpose of the utility model is to solve the problems in the prior art and propose a sewage aeration device for water treatment, which can increase the dissolution efficiency of wastewater.

[0006] To achieve the above object, the present utility model provides a water treatment sewage aeration device, comprising: a pool body and an aeration mechanism disposed at the bottom of the pool body.

Using the cavity as a transfer, the liquid enters the transmission pipe 6 communicated with it and fixedly connected to the rotating column 4. The cavity conveys the liquid into the transmission pipe 6, enabling the transmission pipe 6 to convey the liquid into the nozzle 7 communicated with it. Then, due to the rotation of the rotating column 4, the liquid is evenly conveyed on the liquid surface of the liquid, so that the bubbles generated by aeration come into contact with the liquid again, thereby increasing the contact time between the bubbles and the liquid and further improving the dissolution effect of the liquid.

A horizontally arranged first conveying pipe is fixedly connected vertically to the rotating pipe, and a second conveying pipe is fixedly connected to the first conveying pipe. By using the control panel fixedly connected to the pool body and the solenoid valve fixedly connected to the second conveying pipe, when the solenoid valve is opened, the liquid at each liquid level can be extracted.

[0037] Specifically, a waterproof column 18 is fixedly connected vertically to the pool body 1, and the rotating column 4 is rotatably connected to the waterproof column 18, mainly for supporting the rotating column 4.

[0038] Specifically, an external gear ring 19 is fixedly connected to the rotating column 4, and a straight gear 20 meshing with the external gear ring 19 is rotatably connected to the waterproof column 18. By fixedly connecting the output shaft of the motor 21 fixedly connected to the waterproof column 18 to the straight gear 20, the rotation of the rotating column 4 can be achieved.

[0039] Specifically, a support plate 22 is fixedly connected to the rotating column 4, and the support plate 22 is fixedly connected to the transmission pipe 6, mainly for supporting the transmission pipe 6.

[0040] Specifically, a filter screen 23 is fixedly connected to the pool body 1, and the filter screen 23 mainly prevents impurities from clogging the aeration mechanism 2.
