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] A housing, wherein the housing has an internal cavity for storing the liquid medicine;

[0009] The connecting end is located at the bottom of the housing for connection, and a connecting channel is provided inside the connecting end, which communicates with the cavity;

[0010] A cover plate, which covers the upper part of the housing to seal the upper part of the housing;

[0011] The spray nozzle is located on the upper part of the housing and is used to connect the internal cavity of the housing with the outside.

[0012] An elastic ring, which has elasticity, is circumferentially fitted around the upper part of the housing and is used to seal the spray nozzle.

[0013] In some embodiments, the housing is a cylindrical structure.

[0014] In some embodiments, the diameter of the cover plate is larger than the diameter of the housing, the housing is provided with an annular platform below the spray nozzle, an annular groove is formed between the outer extension of the cover plate and the annular platform, and a tension ring is disposed in the annular groove.

[0015] In some embodiments, multiple sets of spray nozzles are evenly arranged, and the multiple sets of spray nozzles are arranged in a circumferential direction at the same height of the housing.

[0016] In some embodiments, the connecting end and the housing are an integral structure, and the connecting end is a cylindrical structure with a connecting channel in the middle.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] This invention utilizes a tension ring at the spray nozzle to control the opening and closing of the nozzle by adjusting the pressure provided by the pesticide supply end, thus ensuring a consistent pesticide supply. Furthermore, this invention ensures that the tension ring experiences uniform force on the outside of the housing, resulting in consistent sealing force on each spray nozzle. This guarantees that each nozzle opens or closes simultaneously, ensuring even pesticide spraying. Attached Figure Description

[0021] 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.

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.

[0023] like Figure 1 As shown, a spray head for a crystallization granulation catalytic softening fluidized bed includes:

[0024] The housing 1 has an internal cavity 2 for storing the liquid medicine.

[0025] Connection end 3, the connection end 3 is set at the bottom of the housing 1 for connection, and the connection end 3 is provided with a connection channel 4, which communicates with the cavity 2;

[0026] Cover plate 5, which covers the upper part of housing 1 and is used to seal the upper part of housing 1;

[0027] Spray nozzle 9, which is located on the upper part of the housing 1, is used to connect the cavity 2 inside the housing 1 with the outside.

[0028] An elastic ring 6, which has elasticity, is circumferentially fitted around the upper part of the housing 1 to seal the spray nozzle 9. The elastic ring 6 can be made of rubber or silicone.

[0029] Specifically, connection end 3 is connected to the liquid supply end, which supplies liquid medicine to cavity 2 through connection end 3. The liquid supply end provides pressure; when cavity 2 is filled with liquid medicine, the liquid medicine, driven by the pressure, flows towards the spray nozzle 9, pushing open the tension ring 6, and then is sprayed into the fluidized bed. When the pressure at the liquid supply end decreases, the liquid medicine can no longer push open the tension ring 6 sealing the spray nozzle 9, thus closing the spray nozzle 9.

[0030] Compared to directly closing the spray nozzle 9 using a switch, although the pressure reduction at the pesticide supply end in this application is gradual, the spray nozzle 9 closes directly when the pressure falls below a certain value, without a gradual process. Therefore, the pesticide supply can be guaranteed.

[0031] The housing 1 has a cylindrical structure. The diameter of the cover plate 5 is larger than the diameter of the housing 1. An annular platform 7 is provided on the lower side of the spray nozzle 9 on the housing 1. An annular groove 8 is formed between the outer extension of the cover plate 5 and the annular platform 7. The tension ring 6 is disposed in the annular groove 8. Multiple sets of spray nozzles 9 are evenly arranged, and the multiple sets of spray nozzles 9 are arranged in the same circumferential direction at the same height of the housing 1. In this embodiment, four spray nozzles 9 are provided.

[0032] Specifically, the housing 1 is designed as a cylindrical structure, which can ensure that the tension ring 6 is evenly stressed on the outside of the housing 1. Therefore, the tension ring 6 exerts the same sealing force on each spray nozzle 9, thereby ensuring that each spray nozzle 9 opens or closes at the same time.

[0033] The cover plate 5 is also a circular structure. It covers the upper part of the housing 1 and is integral with the housing 1, ensuring that the liquid can only be sprayed out from the spray nozzle 9. Since the diameter of the cover plate 5 is larger than the diameter of the housing 1, the outer extension of the cover plate 5 extends to the outside of the housing 1. The outer extension of the cover plate 5 and the annular platform 7 form an annular groove 8 to limit the position of the tension ring 6 and ensure that the tension ring 6 seals the spray nozzle 9.

[0034] The connecting end 3 and the housing 1 are an integral structure, and the connecting end 3 is a cylindrical structure with a connecting channel 4 in the middle.

[0035] 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.
