Technical Field

[0001] The utility model relates to the technical field of ammonia water preparation, in particular to a static mixing device for ammonia water preparation. Background Technique

[0002] When preparing ammonia water, the role of using a static mixing device is to improve the mixing efficiency and stability, and at the same time reduce energy consumption and costs. Through its special structure and the movement of fluids, this device disperses immiscible fluids respectively and mixes them with each other, thus achieving a good mixing effect and improving the efficiency and stability of ammonia water preparation.

[0003] In the prior art, when using a static mixing device to produce and prepare ammonia water, generally ammonia gas and water are mixed to form ammonia water to achieve the purpose of rapid preparation. However, considering that in some cases, the water pressure of the water flow sent out from the main water pipe is too large, resulting in the risk that the water flow will overflow and flow back into the ammonia gas interface during the actual preparation of ammonia water, thus affecting the normal introduction operation of ammonia gas. Therefore, a static mixing device for ammonia water preparation is proposed for the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a static mixing device for ammonia water preparation to solve the problem of easy backflow caused by large water pressure when using a static mixing device to produce and prepare ammonia water in the prior art as mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

A central connector is provided at the center position on the right side of the opening. A connecting stud is threadedly connected to the left side of the central connector. A pressure reducing cone head is fixedly connected to the side of the connecting stud away from the central connector. A diversion cavity communicating with the opening is provided on the outer surface of the pressure reducing cone head. An outer clamping ring is fixedly connected to the outside of the pressure reducing cone head. Support rods fixedly connected to the pressure reducing sleeve are respectively fixedly connected to the upper and lower ends of the central connector.

[0007] Preferably, mixing vanes are fixedly connected inside the mixing sleeve. First flange plates are respectively fixedly connected to the right side of the mixing sleeve and the left side of the pressure reducing sleeve.

[0008] Preferably, a gas pipe interface body is connected to the top of the mixing sleeve. A second flange plate is fixedly connected to the top of the gas pipe interface body. The connection between the second flange plate and the gas pipe interface body forms a "T" - shaped structure.

[0009] Preferably, the central card connector and the pressure reducing sleeve are coaxially arranged, and the total length of a group of the support rods is equal to the outer diameter of the outer snap ring.

[0010] Preferably, the left end of the spring extends to the inside of the outer snap ring and abuts against the right end of the pressure reducing cone head, and the shunt channels are arranged in an annular array structure along the outer surface of the pressure reducing cone head.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In the present utility model, through the central card connector, the adapter stud, the pressure reducing cone head, the shunt channels, the outer snap ring, the spring and the support rods provided, it is convenient for the static mixing device for ammonia water preparation to introduce water flow and ammonia gas. Before subsequent mixing and preparation operations, under the connection action of the pressure reducing sleeve and the notch, the shunt type pressure reducing and buffering structure composed of the central card connector, the adapter stud, the pressure reducing cone head, the shunt channels, the outer snap ring, the spring and the support rods is used to perform pressure reducing adjustment on the water flow with a relatively high water pressure.

Detailed Embodiments

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0020] A static mixing device for ammonia water preparation, including a decompression sleeve 1, a notch 2 is provided inside the decompression sleeve 1, a central card joint 3 is provided at the central position on the right side of the notch 2, a connecting stud 4 is threadedly connected to the left side of the central card joint 3, a decompression cone head 5 is fixedly connected to the side of the connecting stud 4 away from the central card joint 3, a diversion cavity 6 communicating with the notch 2 is provided on the outer surface of the decompression cone head 5, an outer clamping ring 7 is fixedly connected to the outside of the decompression cone head 5, support rods 14 fixedly connected to the decompression sleeve 1 are respectively provided at the upper and lower ends of the central card joint 3, a spring 8 is provided at the side of the support rod 14 close to the decompression cone head 5, and a mixing sleeve 9 is connected to the right side of the decompression sleeve 1.

[0021] As Figure 1 shown, mixing blades 11 are fixedly connected inside the mixing sleeve 9, first flange plates 10 are respectively fixedly connected to the right side of the mixing sleeve 9 and the left side of the decompression sleeve 1. The mixing blades 11 are fixedly installed, which is conducive to the whole device to prepare ammonia water in a static mixing manner; an air pipe interface body 12 is connected to the top of the mixing sleeve 9, a second flange plate 13 is fixedly connected to the top of the air pipe interface body 12, and the connection between the second flange plate 13 and the air pipe interface body 12 forms a "T" structure, which is conducive to the whole device to be quickly connected to the ammonia gas transmission pipeline.

[0022] As Figure 1 and Figure 2 shown, the central card joint 3 and the decompression sleeve 1 are coaxially arranged, the total length of a group of support rods 14 is equal to the outer diameter of the outer clamping ring 7, and the setting of the central card joint 3 mainly plays a role in assisting the combined installation of the decompression cone head 5.

[0023] As Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the left end of the spring 8 extends to the inside of the outer retaining ring 7 and abuts against the right end of the pressure reducing cone head 5, and the diverter cavity 6 is arranged in a ring array structure along the outer surface of the pressure reducing cone head 5. With the cooperation of the abutting arrangement, the spring 8 will be impacted by the water flow and will generate a reaction force on the pressure reducing cone head 5, so that the entire diverter type pressure reducing buffer structure can reduce the pressure of the water flow.

[0024] Working process: Before the photoelectric device in the utility model is used, after the main water pipe and the ammonia discharge pipeline are respectively connected through a group of first flanges 10, the air pipe interface body 12 and the ammonia discharge pipeline can be quickly connected together through a single second flange 13. When the static mixing device for preparing ammonia water is needed, the treated water flows through the main water pipe and is gradually sent into the interior of the pressure reducing sleeve 1, and the ammonia gas during the preparation of ammonia water is gradually sent into the interior of the mixing sleeve 9 through the air pipe interface body 12. First, the water flows through the interior of the pressure reducing sleeve 1 to be effectively reduced in pressure, and when it is sent into the interior of the mixing sleeve 9, the entire device will statically mix the ammonia gas and water through the mixing blades 11, so that they can be mixed into ammonia water in the interior of the mixing sleeve 9. Then it is taken out through the discharge pipeline, so as to achieve the purpose of preparing ammonia water, and because the pressure reducing cone head 5 is quickly connected to the center clamp joint 3 through the adapter stud 4, it can be pre-assembled into the interior of the pressure reducing sleeve 1. When the water flow with higher water pressure passes through the interior of the pressure reducing sleeve 1 and is sent into the interior of the mixing sleeve 9, under the connection and limiting effect of the center clamp joint 3, the adapter stud 4 and the support rod 14, the pressure reducing cone head 5 uses the multiple diversion cavities 6 reserved on its own surface to divert the unidirectional water flow, and at the same time, it will divert and buffer the water flow together with the reaction force generated by the water flow stamping of the spring 8, so as to cooperate with the device to achieve the purpose of buffering and reducing the pressure of the water flow, and avoid the backflow problem of the water flow with higher water pressure when entering the interior of the mixing sleeve 9.

[0025] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
