[0002] Ammonia water dilution and mixing refers to the process of mixing concentrated ammonia water with water or a diluent to reduce its concentration. In the fields of chemical engineering, pharmaceuticals, environmental protection, etc., ammonia water dilution and mixing is widely used in various ammonia water-related process flows.

[0003] In the prior art, during the ammonia water dilution process, the industry usually uses an increased blade stirrer to achieve the dilution and mixing of ammonia water. This method has problems such as low mixing efficiency and insufficient mixing uniformity, which affect the effect of ammonia water dilution and the stability of subsequent processes. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is that the traditional ammonia water dilution by the method of blade stirring and mixing is uneven and has low mixing efficiency.

[0005] To achieve the above object, the technical solution provided by the utility model is as follows:

[0006] An ammonia water dilution and mixing device includes a support rod, and also includes a mixing kettle and a mixing mechanism. The mixing kettle is fixedly connected to the upper ends of several support rods. The mixing mechanism is connected inside the mixing kettle to adjust the ammonia water dilution and mixing efficiency. One upper side of the mixing kettle is fixedly connected and communicated with a liquid inlet pipe, and a first control valve is connected to the liquid inlet pipe to control the opening and closing of the liquid inlet pipe. One lower side of the mixing kettle is fixedly connected and communicated with a liquid outlet pipe, and a second control valve is connected to the liquid outlet pipe to control the opening and closing of the liquid outlet pipe.

[0007] Further, the mixing mechanism includes a motor and a mixing pipe. The mixing pipe is rotatably arranged inside the mixing kettle. A plurality of spray holes are arranged on the inner wall of the mixing pipe. The number of the mixing pipes is two. The two ends of the two mixing pipes are fixedly connected and communicated through a first connecting pipe and a second connecting pipe respectively. The second connecting pipe and the first connecting pipe are respectively rotatably attached to the upper and lower inner walls of the mixing kettle. The first connecting pipe is fixedly connected to the output end of the motor. A control pump is fixedly connected in the second connecting pipe. An input pipe is fixedly connected to the upper end of the control pump. The input pipe rotatably extends out of the upper end of the mixing kettle, and a third control valve is connected to the input pipe.

[0012] The beneficial effects achieved by the present utility model with the above structure are as follows:

[0022] As Figures 1-5As shown in the figure, an ammonia water dilution and mixing device includes a support rod 1, a mixing kettle 2 and a mixing mechanism 3. The mixing kettle 2 is fixedly connected to the upper ends of several support rods 1. The mixing mechanism 3 is connected inside the mixing kettle 2 to adjust the dilution and mixing efficiency of ammonia water. One upper side of the mixing kettle 2 is fixedly connected and communicated with a liquid inlet pipe 201. A first control valve 202 is connected to the liquid inlet pipe 201 to control the opening and closing of the liquid inlet pipe 201. One lower side of the mixing kettle 2 is fixedly connected and communicated with a liquid outlet pipe 203. A second control valve 204 is connected to the liquid outlet pipe 203 to control the opening and closing of the liquid outlet pipe 203.

[0023] As Figure 4 , 5 shown in the figure, in order to achieve the dilution and mixing of ammonia water, the mixing mechanism 3 includes a motor 301 and a mixing pipe 302. The mixing pipe 302 is rotatably arranged inside the mixing kettle 2. A number of spray holes 311 are provided on the inner wall of the mixing pipe 302. The number of the mixing pipes 302 is two. The two ends of the two mixing pipes 302 are fixedly connected and communicated through a first connecting pipe 303 and a second connecting pipe 304 respectively. The second connecting pipe 304 and the first connecting pipe 303 are respectively rotatably attached to the upper and lower inner walls of the mixing kettle 2. The first connecting pipe 303 is fixedly connected to the output end of the motor 301. A control pump 305 is fixedly connected in the second connecting pipe 304. An input pipe 306 is fixedly connected to the upper end of the control pump 305. The input pipe 306 rotatably extends out of the upper end of the mixing kettle 2. A third control valve 307 is connected to the input pipe 306.

[0024] As Figure 4 , 5 shown in the figure, the mixing pipe 302 is arranged in a spiral shape. The two mixing pipes 302 are in a double - spiral structure, which can not only improve the uniformity of ammonia water dilution and mixing, but also increase the number of spray holes 311 to improve the dilution and mixing efficiency of ammonia water. A straight pipe 309 is fixedly connected and communicated between the two mixing pipes 302. A number of spray heads 310 are fixedly connected and communicated with the straight pipe 309. The number of the spray heads 310 is several. The spray heads 310 on both sides of the straight pipe 309 are symmetrically arranged and are staggered with each other, so as to promote the dilution and mixing efficiency and uniformity of ammonia water through the mutual cooperation of the straight pipe 309 and the mixing pipe 302.

[0025] As Figures 3-5 shown in the figure, two limiting members 308 are symmetrically fixedly connected to the upper end of the second connecting pipe 304. A limiting groove 205 is provided on the upper inner wall of the mixing kettle 2. The limiting members 308 are slidably fitted in the limiting groove 205, so as to improve the rotational stability of the mixing pipe 302 inside the mixing kettle 2.

[0026] When the utility model is in use, the first control valve 202 is opened to open the liquid inlet pipe 201, and then ammonia water is injected into the mixing kettle 2 through the liquid inlet pipe 201. The third control valve 307 is opened to open the input pipe 306, and then the diluent or clear water is introduced through the input pipe 306. The control pump 305 is used to introduce the diluent or clear water into the mixing pipe 302 and the straight pipe 309 through the first connecting pipe 303, and then the diluent or clear water is sprayed in the mixing kettle 2 through the spray holes 311 and the spray head 310. At the same time, the output end of the motor 301 drives the mixing pipe 302 to rotate in the mixing kettle 2 through the first connecting pipe 303 to stir the ammonia water, so that the diluent or clear water rotates and sprays along with the installation rotation, so that the diluent or clear water is mixed with the ammonia water to realize the dilution and mixing of the ammonia water. At the same time, the limiting part 308 at the upper end of the second connecting pipe 304 slides in the limiting groove 205 to improve the stability of the rotation of the mixing pipe 302. After the ammonia water is diluted and mixed, the second control valve 204 is used to control the discharge of the mixing kettle 2 through the liquid outlet pipe 203 and be collected.

[0027] In summary: in the embodiment of the utility model, after the ammonia water is injected into the mixing kettle 2 through the liquid inlet pipe 201, the diluent or clear water is input through the input pipe 306. When the ammonia water is stirred by the mixing mechanism 3, the diluent or clear water is mixed into the ammonia water by using the spray holes 311 and the spray head 310 to realize the dilution and mixing of the ammonia water. The mixing efficiency is high and the mixing is uniform. The straight pipe 309 and the mixing pipe 302 with a double spiral structure rotate at the same time to promote the dilution and mixing of the ammonia water, and further improve the mixing efficiency and the mixing uniformity of the ammonia water dilution and mixing.

[0028] The above describes the present utility model and its implementation manners. This description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the creative purpose of the present utility model, they should all fall within the protection scope of the present utility model.
