[0002] Wastewater treatment: The process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical care, and catering, and is increasingly entering the daily lives of ordinary people.

[0003] Wastewater contains a large number of recalcitrant substances that cannot be effectively removed by a single water treatment device. Therefore, it is often necessary to rationally add wastewater treatment agents according to the specific characteristics of the wastewater to ensure that the treated wastewater meets national discharge standards. Commonly used wastewater treatment agents include flocculants, coagulants, conditioners, demulsifiers, pH adjusters, disinfectants, oxidizing and reducing agents, and defoamers. These agents are generally in solid powder form. When treating wastewater, multiple agents are usually mixed with water for use. Currently, wastewater treatment agents are generally mixed manually, which is time-consuming, labor-intensive, and has low mixing efficiency, thus reducing the efficiency of wastewater treatment. Therefore, this utility model proposes a wastewater treatment agent mixing device for domestic wastewater treatment to solve the above problems. Utility Model Content

[0004] To address the aforementioned problems, this utility model proposes a wastewater treatment agent mixing device for domestic sewage treatment, thereby solving the problem that the existing technology requires manual mixing of wastewater treatment agents, which is time-consuming, labor-intensive, and has low mixing efficiency, thus reducing the efficiency of sewage treatment.

[0005] To achieve the purpose of this utility model, the present utility model is implemented through the following technical solution: a sewage treatment agent mixing device for domestic sewage treatment, including a tank, a discharge pipe and a feed pipe, wherein the bottom end of the tank is connected to the discharge pipe, one side of the top of the tank is connected to the feed pipe, a stirring mechanism is provided inside the tank, a fixing frame is fixedly connected to the top of the tank, a mixing tank is fixedly connected to the top of the fixing frame, a powder tank and a liquid tank are respectively provided on both sides of the mixing tank and are connected to the inside of the mixing tank through a connecting pipe, a modulation mechanism is provided on the top of the mixing tank, and the bottom end of the mixing tank is connected to the top of the tank through a conveying pipe.

[0007] A further improvement is that the top of the mixing tank, powder tank and liquid tank are provided with end caps, the end cap at the top of the mixing tank is provided with an exhaust hole, and the outer wall of the piston is fitted and connected to the inner wall of the mixing tank.

[0008] A further improvement is that a drive motor is fixedly installed on the back side of the top of the support frame, and the output end of the drive motor is fixedly connected to the top end of the rotating rod.

[0017] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0018] according to Figure 1 , 2 As shown in Figure 3, this embodiment proposes a wastewater treatment agent mixing device for domestic wastewater treatment, including a tank 1, a discharge pipe 2, and an inlet pipe 3. The bottom end of the tank 1 is connected to the discharge pipe 2, and one side of the top of the tank 1 is connected to the inlet pipe 3. A stirring mechanism is provided inside the tank 1. A fixing frame 17 is fixedly connected to the top of the tank 1, and a mixing tank 4 is fixedly connected to the top of the fixing frame 17. Powder tanks 5 and liquid tanks 6 are respectively provided on both sides of the mixing tank 4, and are connected to the interior of the mixing tank 4 through a connecting pipe 8. The top of the mixing tank 4 is equipped with a mixing mechanism. The bottom of the mixing tank 4 is connected to the top of the tank body 1 through the conveying pipe 13. Wastewater is transported into the interior of the tank body 1 through the feed pipe 3. Powdered medicine and water are added to the powder tank 5 and liquid tank 6 respectively according to the ratio. The mixing mechanism mixes the powdered medicine and water into a medicine inside the mixing tank 4. Then, the medicine is transported into the interior of the tank body 1 through the conveying pipe 13. The stirring mechanism will stir the medicine and wastewater evenly to make them completely integrated. The mixed wastewater is transported to the next equipment for treatment through the discharge pipe 2.

[0019] The modulation mechanism includes a support frame 7, a connecting pipe 8, a sliding rod 9, a rotating rod 11, and a connecting rod 12. The top of the mixing barrel 4 is provided with a support frame 7. The top of the support frame 7 is rotatably connected to the rotating rod 11. The bottom end of the rotating rod 11 is hinged to the connecting rod 12. The bottom end of the connecting rod 12 is hinged to the sliding rod 9. The bottom end of the sliding rod 9 passes through the interior of the mixing barrel 4 and is fixedly connected to a piston 10.

[0020] The mixing tank 4, powder tank 5 and liquid tank 6 are provided with end caps at their top ends. The end cap at the top end of the mixing tank 4 is provided with an exhaust hole. The outer wall of the piston 10 is fitted and connected to the inner wall of the mixing tank 4.

[0021] A drive motor 18 is fixedly installed on the back side of the top of the support frame 7, and the output end of the drive motor 18 is fixedly connected to the top end of the rotating rod 11.

[0022] The output of the drive motor 18 drives the rotating rod 11 to rotate at the top of the support frame 7. The top of the sliding rod 9 is hinged to the rotating rod 11 through the connecting rod 12. While the rotating rod 11 is making circular motion, it drives the sliding rod 9 to move up and down reciprocally through the connecting rod 12. The piston 10 is fixed at the bottom of the sliding rod 9, which drives the piston 10 to move up and down reciprocally inside the mixing tank 4. The air inside the mixing tank 4 is vented through the exhaust port, so that the inside of the mixing tank 4 is in a negative pressure state. Through the effect of air pressure difference, the raw materials inside the powder tank 5 and the liquid tank 6 are attracted into the mixing tank 4 for mixing. Specifically, the valve connected to the liquid tank 6 is opened first. The piston 10 moves upward to draw water from the liquid tank 6 into the mixing tank 4. Then, the valve on the liquid tank 6 is closed, and the valve connected to the powder tank 5 is opened. The piston 10 moves downward to drain the water from the mixing tank 4 into the powder tank 5 to mix with the powder. The mixed liquid from the powder tank 5 is then drawn into the mixing tank 4, and the mixed liquid is then drained into the powder tank 5. This process is repeated several times until the powder and water are completely mixed. Finally, the mixed liquid from the powder tank 5 is drawn into the mixing tank 4, the valve connected to the powder tank 5 is closed, and the valve on the conveying pipe 13 is opened to transport the medicine into the tank 1 through the conveying pipe 13.

[0023] A rotary motor 16 is fixedly installed on the top of the tank body 1. The output end of the rotary motor 16 passes through the top of the tank body 1 and is fixedly connected to the top of the rotating shaft 14. The output end of the rotary motor 16 can drive the rotating shaft 14 to rotate inside the tank body 1. The stirring blade 15 is fixed to the rotating shaft 14 as a whole. The rotating shaft 14 can drive the stirring blade 15 to rotate inside the tank body 1. The stirring blade 15 can stir the sewage and the medicine to mix with each other.

[0024] The bottom of the tank body 1 is designed as a bucket shape, and the bottom of the tank body 1 is provided with an outer edge, with fixed feet symmetrically fixedly connected to both sides of the outer edge.

[0025] In this wastewater treatment reagent mixing device, piston 10 moves up and down inside mixing tank 4, venting air from the tank through the exhaust port to create a negative pressure state inside mixing tank 4. This pressure difference attracts raw materials from powder tank 5 and liquid tank 6 into mixing tank 4 for mixing. Specifically, the valve connected to liquid tank 6 is first opened, causing piston 10 to move upwards and draw water from liquid tank 6 into mixing tank 4. Then, the valve on liquid tank 6 is closed, and the valve on powder tank 5 is opened. The valve connected to the material tank 5 and the piston 10 move downward to drain the water inside the mixing tank 4 into the powder tank 5 to mix with the powder medicine. Then, the mixed liquid inside the powder tank 5 is drawn into the mixing tank 4, and the mixed liquid is drained into the powder tank 5 again. This process is repeated several times until the powder medicine and water are completely mixed. Finally, the mixed liquid inside the powder tank 5 is drawn into the mixing tank 4, the valve connected to the powder tank 5 is closed, and the valve on the conveying pipe 13 is opened to transport the medicine into the tank 1 through the conveying pipe 13.
