Description

Technical Field

[0001] This utility model belongs to the technical field of spraying equipment for catalytic softening devices used in crystallization granulation, specifically a catalytic softening device for crystallization granulation. Background Technology

[0002] The operating principle of chemical crystallization granulation fluidized bed softening tower 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 tower, 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 react with the hardness components in the water, generating CaCO3 crystals with low solubility.

[0004] Therefore, how to ensure that the seed crystals react fully with water in the crystallization granulation fluidized tower is an urgent problem to be solved in this field. Summary of the Invention

[0005] To address the issue of sufficient reaction between seed crystals and water, this invention provides a catalytic softening device for crystallization granulation.

[0012] The lower plate and the upper plate are connected to the drug inlet, and the drug inlet is connected to the drug inlet.

[0013] Multiple spray heads are provided and are evenly arranged on the upper side of the upper plate and communicate with the inlet space.

[0014] A mixing cylinder, which is mounted on an upper plate;

[0015] A connecting cylinder, the lower end of which is connected to the space at the bottom of the lower plate, and the upper end of which passes through the lower plate and the upper plate and connects to the mixing cylinder.

[0017] In some embodiments, a diversion plate is provided directly above each of the water inlet cylinders, and the diversion plate is disposed within the drug inlet space.

[0018] In some embodiments, the connecting cylinder includes a cylinder body that passes through a lower plate and an upper plate, and an outlet I is provided at the top of the cylinder body;

[0019] The mixing cylinder includes a cover cylinder, which is sleeved outside the outlet I, and the cover cylinder is provided with multiple outlets II.

[0020] In some embodiments, the spray head includes:

[0021] A housing, wherein the housing has an internal cavity for storing the liquid medicine;

[0022] 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;

[0023] A cover plate, which covers the upper part of the housing to seal the upper part of the housing;

Detailed Implementation

[0037] 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.

[0038] like Figure 1 As shown, a catalytic softening device for crystallization granulation includes:

[0039] The tower body 1 has a reaction space inside, a water outlet 2 at the top of the tower body 1, and a sewage outlet 6 at the bottom of the tower body 1; an overflow valve 3 is installed on one side of the upper part of the tower body 1; the tower body 1 is mounted on a support 7.

[0040] Water inlet 4 is located at the lower part of the tower body 1;

[0041] A drug mixing device is installed inside the tower body 1 and is located above the water inlet 4.

[0042] The drug inlet 5 is connected to the drug mixing device and the drug supply end.

[0043] Specifically, the working principle is as follows:

[0044] After the water enters the tower body 1 from the bottom of the inlet 4, the water rises continuously. After passing through the drug mixing device, it reacts chemically with the seed crystals provided by the drug mixing device, and then exits from the outlet 2 set at the top of the tower body 1.

[0045] like Figure 2 As shown, the drug mixing device includes:

[0046] The lower plate 9 and the upper plate 10 are connected to the drug inlet 5, and the drug inlet 9 and the upper plate 10 are connected to the drug inlet 5.

[0047] Multiple spray heads 11 are provided and are evenly arranged on the upper side of the upper plate 10 and communicate with the inlet space.

[0048] Mixing cylinder 12, which is mounted on upper plate 10;

[0049] The connecting cylinder 13 is connected at its lower end to the space at the bottom of the lower plate 9, and at its upper end, it passes through the lower plate 9 and the upper plate 10 and connects to the mixing cylinder 12.

[0050] Specifically, water enters the mixing cylinder 12 from the connecting cylinder 13, and then enters the space above the upper plate 10 from the mixing cylinder 12. After passing through this tortuous path, water molecules are more likely to react with the seed crystals sprayed out by the spray head 11.

[0051] Specifically, multiple water inlet cylinders 8 are evenly arranged on the lower plate 9, and the water inlet cylinders 8 are connected to the medicine inlet 5.

[0052] Each water inlet tube 8 allows the liquid medicine from the inlet 5 to enter the inlet space, where it first undergoes a preliminary chemical reaction with the seed crystals entering from the inlet 5. Then, it is sprayed into the space above the upper plate 10 through the spray head 11 to undergo another chemical reaction with the seed crystals, thereby improving the reaction efficiency.

[0053] Specifically, a diversion plate 14 is provided directly above each of the water inlet cylinders 8, and the diversion plate 14 is located within the drug inlet space.

[0054] A diversion plate 14 is installed directly above the water inlet cylinder 8, allowing water to enter from the water inlet cylinder 8 and then be diverted to both sides, which can further allow the water to fully react with the seed crystals.

[0055] Specifically, the connecting cylinder 13 includes a cylinder body 13.1, which passes through the lower plate 9 and the upper plate 10, and an outlet I13.2 is provided at the top of the cylinder body 13.1;

[0056] The mixing cylinder 12 includes a cover cylinder 12.1, which is sleeved on the outside of the outlet I13.2, and multiple outlets II12.2 are provided on the cover cylinder 12.1.

[0057] like Figure 4 As shown, the spray head 11 includes:

[0058] The housing 11.1 has an internal cavity 11.2 for storing the liquid medicine;

[0059] A connecting end 11.3 is provided at the bottom of the housing 11.1 for connection. A connecting channel 11.4 is provided inside the connecting end 11.3 and communicates with the cavity 11.2.

[0060] Cover plate 11.5, which covers the upper part of housing 11.1 and is used to seal the upper part of housing 11.1;

[0061] The spray nozzle 11.9 is located on the upper part of the housing 11.1 and is used to connect the cavity 11.2 inside the housing 11.1 with the outside.

[0062] The elastic ring 11.6 has elasticity and is circumferentially fitted around the upper part of the housing 11.1 to seal the spray nozzle 11.9.

[0063] The diameter of the cover plate 11.5 is larger than the diameter of the housing 11.1. The housing 11.1 has an annular platform 11.7 on the lower side of the spray nozzle 11.9. An annular groove 11.8 is formed between the outer extension of the cover plate 11.5 and the annular platform 11.7. The tension ring 11.6 is disposed in the annular groove 11.8.

[0064] Specifically, the connecting end 11.3 is connected to the inlet space, which supplies liquid medicine to the cavity 2 through the connecting end 11.3. The inlet space provides pressure, and when the cavity 11.2 is filled with liquid medicine, the liquid medicine flows towards the spray nozzle 11.9 under pressure, pushing open the tension ring 11.6, and then is sprayed into the fluidized tower. After the pressure in the inlet space decreases, the liquid medicine cannot push open the tension ring 11.6 sealing the spray nozzle 11.9, thus closing the spray nozzle 11.9.

[0065] Compared to directly closing the spray nozzle 11.9 using a switch, although the pressure reduction in the inlet space in this application is gradual, the spray nozzle 11.9 closes directly when the pressure falls below a certain value, without a gradual process. Therefore, the supply of pesticide solution can be guaranteed.

[0066] 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.
