[0027] Example 1

[0028] Please see Figures 1-5 This utility model provides a technical solution:

[0029] A precision dosing device for wastewater treatment includes a mixing tank 1. A stirring mechanism is provided at the bottom of the mixing tank 1. The stirring mechanism includes a stirring motor 10 fixedly installed at the bottom of the mixing tank 1. A stirring shaft 11 is provided at the output end of the stirring motor 10. A turntable 12 is fixedly connected to the end of the stirring shaft 11 away from the stirring motor 10. A fixing plate 13 is fixedly installed inside the turntable 12. A stirring plate 14 is provided on the surface of the fixing plate 13. The stirring mechanism at the bottom of the mixing tank 1 can stir the solution, accelerate the dissolution rate of the raw materials in the water, shorten the dissolution time, and thus improve the efficiency of wastewater treatment.

[0030] The stirring shaft 11 passes through the bottom of the mixing tank 1 and is rotatably installed inside the bottom of the mixing tank 1. The turntable 12 is rotatably installed in the bottom of the mixing tank 1 and the top of the turntable 12 is located inside the mixing tank 1. Through the stirring shaft 11 and the turntable 12, the action of the stirring motor 10 can be transmitted to the stirring plate 14, thereby stirring and mixing the water and raw materials in the mixing tank 1.

[0031] Multiple fixed plates 13 and stirring plates 14 are symmetrically and evenly distributed on the surface of the turntable 12. The stirring plates 14 can stir and mix the water and raw materials in the mixing tank 1. Stirring allows the raw materials to come into full contact with the water, speeds up the dissolution and mixing, and improves the uniformity of the drug mixture.

[0032] In use, first add an appropriate amount of water through the water inlet 2, then add the required raw materials through the feed inlet 3. Then, start the hot air blower 6, which will draw in and heat the air. The hot air will then be discharged into the mixing tank 1 through the hot air pipe 7 to heat the water in the tank. At the same time, start the fan 9 on the top of the mixing tank 1 to accelerate the airflow and make the heat distribution more even. Meanwhile, the stirring motor 10 will also drive the stirring shaft 11 to rotate, which will cause the turntable 12 and the stirring plate 14 to rotate, stirring and mixing the water and raw materials in the tank. During the stirring process, the raw materials will move along the spiral wall 15 on the inner wall of the mixing tank 1, increasing the mixing path and time, so that the raw materials can be more fully dissolved and mixed. After the mixing is completed, the prepared reagent is discharged through the discharge port 4 for the next stage of wastewater treatment.

[0033] Example 2

[0034] Please see Figures 1-5 This utility model provides a technical solution:

[0035] An auxiliary mechanism is provided on one side of the mixing tank 1. The auxiliary mechanism includes a bracket 5 fixedly connected to one side of the mixing tank 1. A hot air blower 6 is fixedly installed inside the bracket 5. The hot air blower 6 in the auxiliary mechanism can heat the air and send it into the mixing tank 1. It can heat the water with hot air to increase the water temperature so as to accelerate the dissolution of the raw materials. It can also maintain the raw materials in a suspended state to avoid sedimentation and ensure that the raw materials can be fully dissolved.

[0036] The bottom of the hot air blower 6 is equipped with an air duct 7. The end of the air duct 7 away from the hot air blower 6 passes through the mixing tank 1 and the opening is set inside the mixing tank 1. The air duct 7 is used to transmit the hot air generated by the hot air blower 6 and accurately and evenly transmit the hot air into the mixing tank 1. It also works in conjunction with the rotating water flow to avoid local overheating or uneven heating, which would lead to uneven dissolution of the raw materials.

[0037] The auxiliary mechanism also includes an air grille 8 fixedly installed on the top of the mixing tank 1. The air grille 8 is equipped with a fan 9 inside. The fan 9 can accelerate the airflow inside the mixing tank 1, promote the uniform distribution of heat, and help the raw materials to mix, thereby improving the mixing efficiency.

[0038] The top of the mixing tank 1 is equipped with a water inlet 2 and a feed inlet 3, and the bottom of the mixing tank 1 is equipped with a discharge outlet 4. The water inlet 2 and the feed inlet 3 are used for water flow and raw material entry, respectively. The discharge outlet 4 is also equipped with a control valve to precisely control the discharge of the agent and accurately supply the agent according to the actual needs of wastewater treatment, so as to achieve precise dosing.

[0039] The inner wall of the mixing tank 1 is fixedly connected with a spiral wall 15, which is a continuous spiral structure. It works in conjunction with the stirring mechanism to make the water flow rotate and drive the raw materials to move along it during the stirring process, increasing the mixing path and time, further improving the mixing effect of the raw materials, making the mixing more thorough and the concentration more uniform, thereby improving the sewage treatment effect.

[0040] Unlike Example 1, the auxiliary mechanism and the spiral wall 15 are designed to increase the water temperature and accelerate the dissolution efficiency while maintaining the raw materials in suspension to prevent sedimentation and ensure full dissolution. On the other hand, the spiral wall 15 drives the raw materials to move along it during the stirring process, increasing the mixing path and time, further improving the mixing effect of the raw materials, making the mixing more thorough and the concentration more uniform, thereby improving the wastewater treatment effect.

[0041] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
