[0020] The technical scheme of the patent will be further described in detail in combination with specific implementation manners.
[0021] Embodiments of the present patent are described below in detail, examples of which are shown in the accompanying drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary only, for the purpose of explanation, and are not to be understood as a limitation of the present patent.
[0022] Embodiment 1: Refer to Figure 1 The medicated drainage pipe comprises a sewage treatment tank 1, a front-end tank 2 and a rear-end tank 3 are arranged in the sewage treatment tank 1, a partition plate 4 is arranged between the front-end tank 2 and the rear-end tank 3, a liquid channel 8 is arranged at the bottom of the partition plate 4, an L-shaped medicated drainage pipe 6 is arranged on one side of the front-end tank 2 close to the partition plate 4, one end of the medicated drainage pipe 6 extending to the rear-end tank 3 through the liquid channel 8 is provided with a vertically arranged mixing pipe 11, an aeration pipe 9 is arranged in the rear-end tank 3 in a ring shape, an aeration head 10 is arranged on the side wall of the aeration pipe 9, and the mixing pipe 11 is in communication with the inside of the aeration pipe 9 at the end away from the medicated drainage pipe 6, a water inlet pipe 7 is arranged on one side of the top of the medicated drainage pipe 6, and an air inlet pipe 5 is arranged in the rear-end tank 3 and in communication with the inside of the mixing pipe 11 at one end.
[0023] As a preferred embodiment of the utility model, one end of the air inlet pipe 5 connected with the side wall of the mixing pipe 11 is located at the middle position of the side wall of the mixing pipe 11, and an air compressor is connected with the end of the air inlet pipe 5 away from the mixing pipe 11.
[0024] As a preferred embodiment of the utility model, the top end opening of the water inlet pipe 7 is located at the bottom of the liquid level in the front-end tank 2.
[0025] Embodiment 2: Refer to Figures 2-3 The medicated drainage pipe is different from the embodiment 1 in that fixed teeth 12 arranged staggeredly are arranged on the inner wall of the mixing pipe 11, the fixed teeth 12 form a complex turbulent flow environment in the mixing pipe 11 through the staggered arrangement, the disturbance effect of the liquid and the compressed air is significantly enhanced, and the mutual contact and mixing process of the solution and the solvent in the medicament liquid are accelerated. The turbulent flow can destroy the laminar flow state of the liquid, so that the medicament liquid and the compressed air are cut and mixed for multiple times when passing through the mixing pipe 11, thereby improving the uniformity of the mixing. Meanwhile, the structure can also reduce the deposition phenomenon of the medicament liquid in the mixing pipe 11, and ensure that the medicament liquid can flow to the aeration pipe 9 efficiently and continuously.
[0026] Embodiment 3: Refer to Figure 4The difference between the medicated drainage tube and the embodiment 1 is that the fixed teeth 12 are arranged upwardly and obliquely, which further optimizes the liquid flow characteristics in the mixing pipe 11 and has a significant effect. First, the upwardly and obliquely arranged fixed teeth 12 can guide the liquid to flow in a specific direction, promote stronger disturbance and cutting effect during the gas-liquid mixing process, and thus greatly enhance the mixing efficiency of the liquid medicine and sewage. Second, the oblique design forms a multi-level flow path when the liquid flows through the mixing pipe 11, effectively breaks the laminar flow state of the liquid, strengthens the turbulent flow effect, and makes the contact between the liquid medicine and the sewage more sufficient and uniform. In addition, the upwardly and obliquely arranged structure can also increase the upward power of the liquid during the liquid flow process, avoiding the deposition or stagnation of the liquid at the fixed teeth 12, thereby ensuring the continuity and stability of the mixing process. Overall, this design not only improves the flow efficiency in the mixing pipe 11, but also significantly improves the uniformity and reaction rate of the mixing of the liquid medicine and the sewage.
[0027] As a preferred embodiment of the utility model, the air inlet pipe 5 is L-shaped structure, the air inlet pipe 5 with the mixing pipe 11 side wall connection one end is arranged upwardly and obliquely, ensure that compressed air can enter the mixing pipe 11 smoothly, and flow along the inside of the mixing pipe 11 towards the aeration pipe 9 direction, thereby providing continuous, stable gas power for the aeration pipe 9, promote the efficient mixing of liquid medicine and sewage. At the same time, this oblique design effectively avoids the reverse flow of compressed air in the mixing pipe 11 to the medicated drainage tube 6, avoids the liquid flow in the medicated drainage tube 6 being blocked due to reverse flow, thereby affecting the medicating effect. This structure optimization not only improves the operating efficiency of the system, but also ensures the stability and continuity of the liquid medicine filling process, and provides protection for the efficient operation of sewage treatment.
[0028] The utility model utilizes the principle of air stripping and multi-point mixing diffusion design to realize the efficient mixing and rapid diffusion of liquid medicine and sewage. The specific working process is that the sewage flows from the front-end pool 2 into the rear-end pool 3, the medicated drainage tube 6 inputs gas into the mixing pipe 11 through the connected air inlet pipe 5, the gas mixes with the liquid medicine to form a gas-liquid mixed flow, and the liquid is pushed to flow rapidly into the mixing pipe 11 of the rear-end pool 3 by the buoyancy and pressure of the gas. One end of the mixing pipe 11 is connected with the aeration pipe 9, and the air stripping effect pushes the liquid medicine to further enter the aeration pipe 9 arranged in a ring shape. The aeration pipe 9 is provided with a plurality of aeration heads 10 on the side wall, and after the liquid medicine enters, the liquid medicine is mixed with the sewage by the multi-point injection of the aeration heads 10 and rapidly diffuses in the pool by the disturbance effect of the gas. Through this rapid flow and multi-point injection diffusion design, the liquid medicine and the sewage are mixed more uniformly, the concentration of the liquid medicine in the pool quickly reaches the theoretical value, and the efficiency of the sewage treatment is significantly improved.
[0029] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
