Description

Technical Field

[0001] This utility model belongs to the technical field of spraying equipment for crystallization granulation catalytic softening fluidized tower, specifically a spraying head for crystallization granulation catalytic softening fluidized tower. Background Technology

[0002] The operating principle of chemical crystallization granulation fluidized bed water softening is to add chemical agents to the water, causing Ca2+ in the water to react chemically to generate CaCO3 crystals, which then attach to the surface of the pre-added seed crystals, thereby reducing the hardness of the water.

[0003] In a fluidized bed crystallization process, a certain proportion of seed crystals are first added to the water. These seed crystals can be high-purity CaCO3 crystals used in industry or natural limestone. Then, an alkaline agent, such as sodium hydroxide or calcium hydroxide, is added to the water to cause the hardness components in the water to react and generate CaCO3 crystals with low solubility.

[0004] The advantages of chemical crystallization granulation fluidized bed water softening technology include good treatment effect, stable operation, and low energy consumption. Furthermore, because this technology uses chemical agents, the degree of hardness removal in the water can be flexibly adjusted to adapt to different water quality conditions and effluent requirements.

[0005] Since chemical reagents need to be uniformly sprayed inside the fluidized bed for reaction in chemical crystallization granulation, a spray head needs to be designed to ensure that the chemical reagents can be sprayed accurately and uniformly. Summary of the Invention

[0006] This invention provides a spray head for a crystallizing, granulating, catalytic softening fluidized bed to solve the problem of uneven spraying of chemical solutions in fluidized bed towers.

[0007] This utility model adopts the following technical solution: a spray head for a crystallization granulation catalytic softening fluidized bed, comprising:

[0008] The spray head has a cavity inside to hold the liquid medicine. The spray head is made of flexible material and has multiple spray holes.

[0009] The connecting end is connected to the spray head, and the connecting channel inside the connecting end is in communication with the cavity.

[0010] In some embodiments, the spray nozzle is made of rubber or silicone.

[0011] In some embodiments, the spray head and the connecting end are an integral structure.

[0012] In some embodiments, the spray nozzle is formed by puncturing the periphery of the spray head with a needle.

[0013] In some embodiments, multiple rows of spray holes are arranged along the spray head from top to bottom, with multiple holes evenly arranged in each row.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This utility model's spray head is made of rubber or silicone. Because the spray head uses a flexible material, the spray orifice is normally closed after its formation due to the inherent physical properties of the flexible material. However, when the cavity is filled with liquid medicine, it exerts an outward pressure on the cavity, which opens the spray orifice, thus uniformly spraying the medicine into the chemical crystallization granulation fluidized tower. This application features spray orifices evenly distributed around the spray head, ensuring timely and uniform liquid medicine spraying. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] The structures, proportions, and sizes illustrated in the accompanying drawings are solely for illustrative purposes and to aid those skilled in the art in understanding and reading the invention. They are not intended to limit the scope of the invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of the invention, should still fall within the scope of the technical content disclosed herein. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of the invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of the invention.

[0020] like Figure 1 As shown, a spray head for a crystallization granulation catalytic softening fluidized bed includes:

[0021] The spray head 1 has a cavity 2 inside for containing liquid medicine. The spray head 1 is made of flexible material and has multiple spray holes 3.

[0022] Connection end 4 is connected to the spray head 1, and the connection channel 5 inside the connection end 4 is connected to the cavity 2.

[0023] Specifically, the connecting end 4 connects the cavity 2 to the liquid supply end. The liquid supply end inputs the liquid into the spray head 1 and provides liquid pressure. After the liquid fills the cavity 2, it is then evenly sprayed into the chemical crystallization granulation fluidized tower through the spray hole 3 for reaction.

[0024] The spray head 1 is made of rubber or silicone. The spray head 1 and the connecting end 4 are an integral structure.

[0025] The spray holes 3 are formed by piercing the spray head 1 with a needle. Multiple rows of spray holes 3 are arranged along the spray head 1 from top to bottom, with multiple holes evenly distributed in each row. The size of the spray holes 3 is such that when the cavity 2 inside the spray head 1 is not full of liquid medicine, the spray holes 3 are closed; when the cavity 2 inside the spray head 1 is full of liquid medicine, the spray holes 3 are open.

[0026] Specifically, when making the spray hole 3, a needle of appropriate size is directly inserted into the spray head 1 to form the spray hole 3. At this time, since the spray head 1 is made of flexible material, the spray hole 3 is normally closed due to the physical properties of the flexible material itself. However, if the liquid medicine in the cavity 2 is filled, it will exert an outward pressure on the cavity 2. Under the action of this pressure, the spray hole 3 will open, thereby evenly distributing the medicine in the cavity 2 into the chemical crystallization granulation fluidized tower.

[0027] When the pressure falls below a certain value, the spray nozzle 3 automatically closes. Compared to directly closing the spray nozzle 3 using a switch, although the pressure reduction at the pesticide supply end in this application is gradual, the spray nozzle 3 closes directly when the pressure falls below a certain value, without a gradual process. Therefore, the pesticide supply can be guaranteed.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
