[0029] In order to solve the problems of uneven mixing of treatment agent and sewage, reaction lag and other problems in the traditional sewage treatment process, and further to solve the problem that sewage and treatment agent cannot be fully contacted and reacted in the initial stage, the utility model provides a sewage treatment agent rapid mixing device for sewage treatment. Figures 1-5 As shown in the figure, including connecting pipeline 1, treatment agent feeding part 2 and stirring part 3, connecting pipeline 1 is the main structure of the device, is provided with water inlet 102 and water outlet 103, water inlet 102 adopts detachable connection mode and can be docked with the drain of sewage treatment pipeline, which is convenient for installation, replacement and subsequent maintenance.In order to adapt to various complex sewage environment, the pipeline material is made of high-strength corrosion-resistant alloy or high-molecular composite material, and the inner surface is treated specially to reduce dirt accumulation and improve durability.Treatment agent feeding part 2 is connected with treatment agent conveying pipeline, treatment agent feeding part 2 is fixed through connecting pipeline 1 and is fixedly arranged in connecting pipeline 1 to spray sewage treatment agent.Stirring part 3 is fixedly arranged in connecting pipeline 1 after treatment agent feeding part 2, which realizes rapid mixing.The whole device in the running process, sewage flows into connecting pipeline 1 from water inlet 102, treatment agent feeding part 2 sprays treatment agent accurately, treatment agent and sewage are preliminarily contacted, and then pass through stirring part 3, rapidly mix and complete chemical reaction under the action of vortex and flow out from water outlet 103.Through the compact structure and continuous process design, the device effectively avoids the time difference caused by the separation of spraying and stirring in the traditional treatment process, significantly shortens the reaction lag time, ensures the full contact and reaction of treatment agent and sewage, improves the reaction efficiency and treatment effect.The rapid mixing device is especially suitable for medium and large sewage treatment system, and has wide application potential in industrial wastewater, municipal sewage and special chemical wastewater treatment.

[0030] In the preferred embodiment, the treatment agent dispensing component 2 includes a dispensing pipe 202 and a mounting ring 201 designed to achieve efficient and precise distribution of the treatment agent, enhancing the initial contact effect with the sewage. The mounting ring 201 is fixedly arranged inside the connecting pipe 1 and made of corrosion-resistant and high-strength materials to ensure its excellent durability and stability during long-term operation. Multiple treatment agent nozzles 204 are uniformly distributed on the outer edge of the mounting ring 201, which are arranged in a circular pattern around the center of the mounting ring 201, forming an annular spraying area. The number and distribution density of the nozzles can be adjusted according to the scale and flow demand of the sewage treatment system, ensuring that the treatment agent can be uniformly sprayed in the form of atomization or fine stream into the sewage in the pipe, avoiding local over-dosing or under-dosing, and creating uniform initial conditions for subsequent agitation mixing. The dispensing pipe 202 passes through the outside of the connecting pipe 1 and communicates with the mounting ring 201, and the outer end of the dispensing pipe 202 is equipped with a dispensing joint 203 for quick connection with the treatment agent delivery pipe. The multi-nozzle annular arrangement structure can significantly expand the spraying coverage of the treatment agent and improve the uniformity of spraying, while allowing the treatment agent to be distributed into the sewage flow in the shortest path, reducing the mixing lag time. Without manual operation, this design not only improves the utilization rate of the treatment agent, but also effectively reduces the operating cost, and the device is simple and low in cost, which can be used in large-scale sewage treatment or high-concentration wastewater treatment. The coordinated work of the overall dispensing component and the agitation component 3 further ensures the thorough mixing of the treatment agent and the sewage, significantly improving the efficiency and reaction effect of the sewage treatment.

[0031] In the preferred embodiment, the multiple treatment agent nozzles 204 are provided with a spraying inclination angle of 30° to 60° towards the center, which further optimizes the spraying effect of the treatment agent and the initial mixing efficiency with the sewage. The nozzles are arranged in a circular pattern around the center of the mounting ring 201, and different spraying angles are used according to the speed of the sewage flow and the diameter of the connecting pipe 1, so that the treatment agent is sprayed at a certain angle to the center area of the connecting pipe 1. This range of central inclination spraying angles (30° to 60°) has been experimentally verified to maximize the contact area of the treatment agent with the sewage without affecting the sewage flow rate, while avoiding the problems of local under-dosing or resource waste caused by too concentrated or too dispersed spraying. The inclination of the spraying angle can also produce a certain cyclone effect, making the sprayed treatment agent form a stronger turbulent mixing state with the sewage, providing a basis for the subsequent mixing of the sewage treatment agent by the agitation component 3.

[0032] In the preferred embodiment, the agitating component 3 comprises a fixed ring 301 fixed inside the connecting pipe 1 and agitating blades 304 rotatably arranged on the fixed ring 301, aiming to provide efficient mixing effect and ensure the sewage and the treatment agent to be in full contact and evenly distributed. The fixed ring 301 comprises a plurality of supports 302 and a connecting piece 303 at the center of the fixed ring 301, ensuring the stability and uniform stress of the whole structure. The supports 302 are evenly distributed circumferentially on the fixed ring 301 and firmly connected with the connecting piece. This structure design not only ensures the strength and stability of the fixed ring 301, but also improves the durability of the agitating component 3, which can withstand the high rotation speed and strong shear force generated during agitation. The agitating blades 304 are rotatably arranged on the connecting piece, and are driven to rotate by the water flow, thereby forming a strong vortex effect in the pipe. The shape and angle of the agitating blades 304 are optimized by fluid mechanics to ensure that they can generate the maximum agitation effect during rotation, so that the treatment agent is rapidly and evenly dispersed in the entire water body.

[0033] In the preferred embodiment, the connecting pipe 1 comprises a pipe body 100, and a flange 101 is arranged at one end of a water inlet 102 of the pipe body 100. The pipe body 100 is connected with the sewage treatment pipe through the flange 101. The flange 101 connection is a common and reliable connection technology, which can ensure the sealing between the pipes and prevent sewage leakage or treatment agent overflow. Especially in high-flow and high-pressure sewage treatment systems, the flange 101 connection has outstanding advantages.

[0034] In the preferred embodiment, the diameter of the water inlet 102 of the connecting pipe 1 is larger than the diameter of the water outlet 103 of the connecting pipe 1. By gradually changing the diameter in this way, the sewage flow at the water inlet 102 is effectively pressurized, so that the sewage flow rate is increased when entering the pipe. This pressurization effect not only promotes the flow of sewage in the pipe, but also cooperates with the agitating component 3 to form a strong vortex effect, enhancing the mixing degree of the sewage and the treatment agent. In addition, as the sewage flows gradually through the pipe, the smaller diameter of the water outlet 103 causes the sewage to be "converged" and accelerated again when flowing out of the pipe. This process not only further stimulates the vortex effect, but also allows the sewage to mix with the remaining treatment agent again after flowing into the sedimentation tank.

[0035] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can easily think of changes or replacements within the technical scope disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
