While this method can achieve the aeration effect, the contact time between the gas and the water is short, the degree of contact exchange is low, and the aeration effect is poor. Therefore, a new type of sewage treatment aeration device is needed to solve the above problems. Utility Model Content

[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0017] The wastewater treatment aeration device provided in this embodiment is mainly used to solve the problem that, in current aeration methods, the air outlet pipe is generally inserted into the wastewater tank to directly introduce oxygen into the wastewater. Although this method can achieve the aeration effect, the contact time between the gas and water is short, the degree of contact exchange is low, and the aeration effect is poor. The following technical solution is provided, which will be discussed in conjunction with... Figures 1-4 Please provide a detailed explanation: A wastewater treatment aeration device includes an air inlet chamber 1 with a first impeller 2 and a second impeller 3 internally arranged. The second impeller 3 is located below the first impeller 2 and rotates in the opposite direction to the first impeller 2. An air vent pipe 5 is fixedly connected to the surface of the air inlet chamber 1. During use, the user places the air inlet chamber 1 into the wastewater, and external oxygen is introduced into the air inlet chamber 1 through the air vent pipe 5. A drive unit 4 simultaneously drives the first impeller 2 and the second impeller 3 to rotate, thus simultaneously drawing wastewater into the air inlet chamber 1 and drawing oxygen into the air inlet chamber 1. Inside, wastewater and oxygen are uniformly mixed. The main components of the air intake chamber 1 are: a main chamber body 11 with several outlets 12 on its surface (the water mixed with oxygen can be discharged from the outlets 12). In use, the user assembles the air intake chamber 1 by installing a secondary chamber body 13 on top of the main chamber body 11 using the installation unit 14. The main components of the drive unit 4 are: a mounting frame 41 fixedly installed on the inner wall of the main chamber body 11, wherein the first impeller 2 is rotatably inserted into the surface of the mounting frame 41. In use, the user controls the output of the drive motor 44, which is fixedly mounted on the surface of the mounting bracket 41, to rotate via the controller 45 fixedly mounted on the surface of the auxiliary chamber 13. This drives the first impeller 2, which is fixedly mounted on the output of the drive motor 44, to rotate. Since the surface of the first impeller 2 is fixedly mounted with the water outlet chamber 42, and the second impeller 3 is fixedly mounted on the inner wall of the water outlet chamber 42, and several mixing tanks 43 are formed on the surface of the water outlet chamber 42, the second impeller 3 is driven by the water outlet chamber 42 during use, thereby discharging the oxygen discharged from the vent pipe 5 below. The gas is drawn to the top of the second impeller 3. After the oxygen is discharged above the second impeller 3, it will be discharged from several mixing tanks 43 to the bottom of the first impeller 2, where it will be further mixed with the sewage below the first impeller 2. This completes the thorough mixing of oxygen and sewage. The main components of the vent pipe 5 are: a main pipe body 51 fixedly inserted into the surface of the main chamber 11 at one end. In use, the user will put the external oxygen supply pipe onto the surface of the external threaded pipe 52 fixedly installed at the other end of the main pipe body 51 to connect the external oxygen supply pipe to the main pipe body 51.

[0018] By installing a first impeller 2 and a second impeller 3 rotating in the opposite direction to the first impeller 2 inside the air intake chamber 1, the user can connect the external air supply pipe and the ventilation pipe 5 to introduce oxygen into the lower part of the second impeller 3. Then, the drive unit 4 controls the first impeller 2 and the second impeller 3 to rotate simultaneously. This allows oxygen to be drawn into the air intake chamber 1 through the second impeller 3 while sewage is drawn into the air intake chamber 1 through the first impeller 2. The sewage and oxygen are thoroughly mixed before being discharged from the air intake chamber 1. In this process, the sewage and oxygen flow in opposite directions, which allows for more thorough mixing.

[0019] By splitting the air intake chamber 1 into a main chamber 11 and a secondary chamber 13 installed on top of the main chamber 11, the user can disassemble the main chamber 11 and the secondary chamber 13 through the installation unit 14 during use, which facilitates the subsequent cleaning of the inner walls of the main chamber 11 and the secondary chamber 13.

[0020] like Figure 3 As shown, in some embodiments, the main components of the installation unit 14 are: a plurality of installation rods 142, and installation edges 141 are provided on the surfaces of the main compartment 11 and the auxiliary compartment 13. In use, the user slides one end of each of the installation rods 142 into the surfaces of the two installation edges 141 respectively, and then screws the installation sleeves 143 onto the surfaces of the installation rods 142 to achieve the assembly of the main compartment 11 and the auxiliary compartment 13.

[0021] like Figure 1 As shown, in some embodiments, two mounting holes 6 are provided on the top of the sub-compartment 13. When in use, the user hooks the crane hook onto the inner wall of the two mounting holes 6 to lift and lower the air intake chamber 1 (to place it into the sewage tank and to remove it from the sewage tank). At the same time, when the air intake chamber 1 is placed at the bottom of the sewage tank, the placement edge 7 on the surface of the air intake chamber 1 will fit against the inner wall of the sewage tank, ensuring the stability of the air intake chamber 1 during the placement process at the bottom of the sewage tank.

[0022] The working process of this utility model is as follows: First, the user needs to hook the crane hook onto the inner wall of the two mounting holes 6, thread the external air supply pipe onto the surface of the external threaded pipe 52, and then turn on the drive motor 44 through the controller 45. Place the air inlet chamber 1 on the inner wall of the sewage tank, which will drive the first impeller 2 and the second impeller 3 to rotate simultaneously, drawing sewage and oxygen into the interior of the air inlet chamber 1 at the same time and in opposite directions, thus achieving full mixing of sewage and oxygen (the power plug of the drive motor 44 is long and the drive motor 44 is waterproof).

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
