[0003] CN108408817A discloses a float-type aerator mixer for sewage treatment. Each mounting plate has a stirring motor fixedly installed on its inner side, and a stirring cylinder fixedly installed on its outer side. A stirring shaft, with one end fixedly connected to the output shaft of the stirring motor, is rolled inside the stirring cylinder. An air inlet is provided on the outer side of the stirring cylinder, communicating with its interior. During movement, a control switch can be operated to rotate an electro-hydraulic actuator, pushing the cylinder and stirring shaft up and down. This prevents the lower end of the stirring shaft from contacting underwater debris and affecting the movement of the float-type aerator mixer.

[0004] The existing floating aeration mixer for sewage treatment has the following disadvantages: after the sewage is treated by aeration, solid-liquid separation is achieved. However, the device does not have a treatment mechanism, which can easily lead to foaming and subsequent flow of the foam along with the clean water into the next process.

[0005] Therefore, a wastewater treatment tank with an adjustable air flotation device is proposed to solve the problems mentioned above. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0020] Please see Figure 1 - Figure 4This embodiment of a wastewater treatment tank with an adjustable air flotation device includes a wastewater treatment tank body 1.

The separation mechanism includes a support frame 10, a servo motor 11, a movable plate 20, a transmission rod 19, a first rotating rod 12, a second rotating rod 16, a slider 13, a connecting frame 14, a scraper 15, a limiting groove 3, a first through groove 2, and a collection frame 4. The lower end face of the support frame 10 is fixedly installed on the upper end face of the sewage treatment tank body 1, the output end of the servo motor 11 is fixedly installed on the top end of the transmission rod 19, the bottom end of the transmission rod 19 is fixedly installed on the inner wall of the movable plate 20, the lower end face of the movable plate 20 is fixedly connected to the top end of the second rotating rod 16, the lower end face of the second rotating rod 16 is fixedly installed on the upper end face of the slider 13, the surface of the slider 13 is slidably sleeved on the inner wall of the connecting frame 14, and the surface of the collecting frame 4 is slidably sleeved on the inner wall of the sewage treatment tank body 1. By setting slider 13, when the surface of slider 13 slides on the inner wall of connecting frame 14, it can push connecting frame 14, realize the left and right swing of connecting frame 14, and at the same time drive scraper 15 to push the air bubbles to both sides inside the sewage treatment tank body 1, so as to realize the separation between air bubbles and liquid. The lower end face of the servo motor 11 is fixedly installed on the upper end face of the support frame 10, and the output end of the servo motor 11 passes through the inner wall of the support frame 10. By setting the servo motor 11, when the servo motor 11 is working, it can drive the rotation of the transmission rod 19; The arc-shaped outer surface of the second rotating rod 16 is fixedly sleeved on the inner wall of the connecting frame 14, and the bottom end of the second rotating rod 16 is rotatably installed on the upper end face of the sewage treatment tank body 1. By setting the second rotating rod 16, it can cooperate with the rotation of the connecting frame 14 and limit the connection frame 14, ensuring the normal swing of the connecting frame 14 and making the process stable and smooth. Among them, four limiting grooves 3 are provided, and the four limiting grooves 3 are provided on the left and right sides of the sewage treatment tank body 1. Among them, the through hole 5 is opened in the inner wall of the collection frame 4, and the surface of the sealing plug 6 is sealed and fitted into the inner wall of the collection box. By setting the sealing plug 6, when the surface of the sealing plug 6 separates from the inner wall of the collection frame 4, the air bubbles collected through the through hole 5 will flow out from the inner wall of the collection frame 4. The treatment mechanism includes an exposure machine 8, a first mounting port, a connecting pipe 7, a second through groove 9, a discharge pipe 17, and a second mounting port. The lower end face of the exposure machine 8 is fixedly installed on the upper end face of the sewage treatment tank body 1. The first mounting port is opened above the sewage treatment tank body 1. The arc-shaped outer surface of the connecting pipe 7 is fixedly sleeved on the inner wall of the sewage treatment tank body 1. The second through groove 9 is opened on the inner wall of the sewage treatment tank body 1. By setting up the exposure machine 8, the bubbles generated during operation are transferred to the top of the scraper 15 through the second channel 9, which facilitates the treatment of the bubbles. The exposure machine 8 is a well-known technology to those skilled in the art, so it is not described in detail in this embodiment. The second installation port is located on the front of the sewage treatment tank body 1, and the arc-shaped outer surface of the discharge pipe 17 is fixedly sleeved on the inner wall of the sewage treatment tank body 1. When activated via discharge pipe 17, the treated wastewater will be discharged from the wastewater treatment tank body 1 through discharge pipe 17.

[0021] The working principle of the above embodiments is as follows: During use, the operator can inject the sewage to be treated into the sewage treatment tank body 1 through the connecting pipe 7. After entering the sewage treatment tank body 1, the aerator draws in air through impeller rotation, jet negative pressure or surface agitation and other mechanisms to form micro bubbles that mix with water and promote oxygen dissolution. For example, submersible jet aerators use submersible pumps to generate high-speed water flow, creating negative pressure at the nozzle to draw in air, which is then sprayed and diffused after fully contacting the water flow in the mixing chamber; while rotary disc aerators use rotating discs to drive wastewater into contact with air, achieving oxygenation, propulsion and mixing functions. The generated bubbles are transferred to the middle of the sewage treatment tank body 1 through the second channel 9, causing the bubbles to float above the liquid. Then, the servo motor 11 is driven to work, and the servo motor 11 controls the transmission rod 19 to rotate. At the same time, the transmission rod 19 drives the movable plate 20, and the movable plate 20 drives the first rotating rod 12 to drive the slider 13 to slide on the inner wall of the connecting frame 14. The connecting frame 14 is limited to one end by the second rotating rod 16, so that the connecting frame 14 can swing left and right during the transmission process. The connecting frame 14 can drive the scraper 15 at the same time during the left and right swing. The scraper 15 pushes the air bubbles above the liquid toward both sides inside the sewage treatment tank body 1, and smoothly enters the collection frame 4 through the first channel 2 to collect the air bubbles, thus completing the separation process in the sewage. After completion, the sealing plug 6 is moved outward from the inner wall of the collection frame 4. Through the through hole 5, the treated bubble liquid can be discharged into the collection box 4 and outward, and the treated wastewater can be transferred to other equipment through the discharge pipe 17. In the next step, as the collection frame 4 slides upward along the side wall of the sewage treatment tank body 1, it detaches from the sewage treatment tank body 1, making it easier to clean the inner wall of the collection frame 4.

[0022] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
