Description

Technical Field

[0001] This utility model relates to a water treatment corrosion inhibitor preparation and dosing device, belonging to the technical field of dosing devices. Background Technology

[0002] The water treatment corrosion inhibitor preparation and dosing device integrates a series of functions such as preparation, storage and dosing. It is widely used in industrial circulating water systems, boiler water treatment, sewage treatment plants and other scenarios. Its core purpose is to protect metal equipment in contact with water, such as pipes, heat exchangers, and reaction vessels, from corrosion by dissolved oxygen, acid and alkali substances, microorganisms and other factors in water by adding corrosion inhibitors in a reasonable manner, thereby extending the service life of the equipment and reducing maintenance costs.

[0003] A scale and corrosion inhibitor dosing device for water treatment, Chinese Patent No. CN208911909U, includes a mixing tank and a dosing tank. The mixing tank is equipped with a motor connected to a stirring rod, which has stirring blades. The mixing tank has a water inlet with a cover, and a chemical inlet on the other side. The dosing tank contains a through pipe with a through hole at its bottom. A first shaft ring and a second shaft ring are connected. The dosing tank has a water inlet on one side. In this device, the fixed shaft and the isolation block are integrated, making operation more stable. This prevents all the chemicals in the mixing tank from flowing into the dosing tank at once; the chemicals are added by cranking the handle when needed.

[0004] Existing corrosion inhibitor dilution devices have shortcomings in controlling the dilution ratio. Most devices use a fixed dilution process and cannot flexibly adjust the mixing ratio of corrosion inhibitor and water according to actual operating conditions such as changes in water quality and fluctuations in the amount of water treated. They also cannot flexibly change the corrosion inhibitor dosing layout according to actual usage needs.

[0005] Therefore, a device for preparing and adding water treatment corrosion inhibitors is proposed. Summary of the Invention

[0006] In view of this, the present invention provides a water treatment corrosion inhibitor preparation and dosing device to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0007] The technical solution of this utility model is implemented as follows: A water treatment corrosion inhibitor preparation and dosing device includes a water treatment dosing tank. A hollow inner column liquid storage chamber is provided between the upper and lower inner walls of the water treatment dosing tank. Multiple partition chamber sealing ring plates are fixedly connected to the inner side wall of the water treatment dosing tank. The multiple partition chamber sealing ring plates are arranged at equal intervals from top to bottom. Multiple first electromagnetic liquid outlet valves are fixedly connected to the front side of the hollow inner column liquid storage chamber. An overflow opening communicating with the first electromagnetic liquid outlet valves is opened on the front side of the hollow inner column liquid storage chamber. A vertical electric guide rail is fixedly connected to the inner side wall of the hollow inner column liquid storage chamber. Multiple inner partition displacement rings are fixedly connected to the output end of the vertical electric guide rail. The inner partition displacement rings are spaced apart from the multiple overflow openings. A second liquid-blocking solenoid valve is fixedly connected to the inner middle of the inner side of the inner partition displacement ring. A liquid inlet conduit is fixedly connected to the upper end of the hollow inner column liquid storage chamber.

[0008] More preferably, a sealing side ring plug is fixedly connected to the outer wall of the inner partition displacement ring, and the sealing side ring plug is in contact with the inner wall of the hollow inner column liquid storage tank.

[0009] More preferably, a bearing connector is installed between the hollow inner column liquid storage tank and the sealing ring plate of the partition tank, and multiple outer annular sleeves are fixedly connected to the outer side of the hollow inner column liquid storage tank.

[0010] More preferably, the left and right ends of the outer annular sleeve are symmetrically and fixedly connected to an outer agitator fan, and the lower end of the water treatment dosing tank is fixedly connected to a motor.

[0011] More preferably, the output end of the motor is connected to the hollow inner column liquid storage tank, and multiple liquid discharge pump blocks are fixedly connected to the left end of the water treatment dosing tank.

[0012] More preferably, the left end of the liquid discharge pump block is fixedly connected to a liquid discharge conduit, and multiple liquid discharge pump blocks cooperate with each other with the corresponding hollow inner column liquid storage tank.

[0013] More preferably, the water treatment dosing tank is filled with a certain amount of ordinary water, and the hollow inner column storage tank is filled with a certain amount of corrosion inhibitor liquid.

[0014] The present invention has the following advantages due to the adoption of the above technical solution:

[0015] I. This utility model precisely injects corrosion inhibitor liquid into a hollow inner column storage tank via a liquid inlet conduit. Multiple partitioned compartment sealing ring plates divide the interior of the water treatment dosing tank into equal-volume dosing compartments, which work in conjunction with the hollow inner column storage tank. During normal storage, the corrosion inhibitor liquid is stably stored. Furthermore, the internal partition displacement ring is driven by a vertical electric guide rail to slide up and down along the inner wall of the hollow inner column storage tank, which can flexibly adjust the liquid space connected to the first electromagnetic outlet valve. This allows for precise control of the amount of corrosion inhibitor liquid entering each dosing compartment, meeting the diverse needs for corrosion inhibitor storage and retrieval under different operating conditions. At the same time, the sealing side ring plug tightly fits the inner wall of the hollow inner column storage tank, effectively preventing leakage of the corrosion inhibitor liquid during liquid space adjustment, ensuring the accuracy and stability of the dilution operation.

[0016] Second, this utility model uses a motor to drive the hollow inner column liquid storage tank to rotate, which in turn drives the outer shaft fan of the agitator to rotate at high speed, so as to strongly agitate the corrosion inhibitor liquid and ordinary water liquid in the dosing chamber. This mechanical agitation method significantly improves the mixing speed and uniformity of the two liquids, so that the corrosion inhibitor can be quickly and fully diluted. The corrosion inhibitor diluted solution that meets the concentration requirements can be prepared in a short time, which greatly improves the dilution efficiency and output quality of the device.

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Example 1

[0028] like Figure 1-6 As shown, this utility model embodiment provides a water treatment corrosion inhibitor preparation and dosing device, including a water treatment dosing tank 1. A hollow inner column liquid storage chamber 3 is provided between the upper and lower inner walls of the water treatment dosing tank 1. Multiple partition chamber sealing ring plates 8 are fixedly connected to the inner side wall of the water treatment dosing tank 1. The multiple partition chamber sealing ring plates 8 are arranged at equal intervals from top to bottom. Multiple first electromagnetic liquid outlet valves 4 are fixedly connected to the front side of the hollow inner column liquid storage chamber 3. An overflow opening 15, which is connected to the first electromagnetic discharge valve 4, is provided on the front side of the hollow inner column liquid storage tank 3. A vertical electric guide rail 16 is fixedly connected to the inner wall of the hollow inner column liquid storage tank 3. Multiple inner partition displacement rings 11 are fixedly connected to the output end of the vertical electric guide rail 16. The inner partition displacement rings 11 and the multiple overflow openings 15 are spaced apart. A second liquid-blocking solenoid valve 13 is fixedly connected to the inner middle of the inner side of the inner partition displacement ring 11. A liquid-guiding conduit 2 is fixedly connected to the upper end of the hollow inner column liquid storage tank 3.

[0029] A sealing side ring plug 12 is fixedly connected to the outer wall of the inner partition displacement ring 11. The sealing side ring plug 12 is in close contact with the inner wall of the hollow inner column liquid storage tank 3. A bearing connector 10 is installed between the hollow inner column liquid storage tank 3 and the sealing ring plate 8 of the partition. Multiple liquid discharge pump blocks 7 are fixedly connected to the left end of the water treatment dosing tank 1. A liquid discharge conduit 14 is fixedly connected to the left end of the liquid discharge pump block 7. The multiple liquid discharge pump blocks 7 cooperate with the corresponding hollow inner column liquid storage tank 3. The water treatment dosing tank 1 is filled with a certain amount of ordinary water liquid, and the hollow inner column liquid storage tank 3 is filled with a certain amount of corrosion inhibitor liquid. Example 2

[0030] like Figure 2 As shown, in one embodiment, a plurality of outer annular sleeves 5 are fixedly connected to the outer side of the hollow inner column liquid storage tank 3, and the left and right ends of the outer annular sleeves 5 are symmetrically fixedly connected to the outer agitator fan 6. The lower end of the water treatment dosing tank 1 is fixedly connected to a motor 9, and the output end of the motor 9 is connected to the hollow inner column liquid storage tank 3.

[0031] During the process of the corrosion inhibitor solution entering the dosing chamber and mixing with ordinary water, the motor 9 drives the rotation of the hollow inner column storage chamber 3, and the outer shaft fan 6 of the agitator also rotates at high speed. During the rotation, the outer shaft fan 6 strongly stirs the corrosion inhibitor solution and ordinary water in the dosing chamber, accelerating the mixing of the two liquids. Through this mechanical stirring method, the dispersion speed and uniformity of the corrosion inhibitor solution in the ordinary water can be significantly improved, so that the corrosion inhibitor can be diluted more quickly and fully, thereby improving the dilution efficiency of the entire device and ensuring that a corrosion inhibitor diluted solution that meets the concentration requirements can be prepared in a short time.

[0032] In operation, the corrosion inhibitor solution is introduced into the hollow inner column storage tank 3 through the liquid inlet conduit 2 until the tank is full. Multiple partition sealing ring plates 8 divide the interior of the water treatment dosing tank 1 into multiple dosing compartments. Under normal storage conditions, the corrosion inhibitor solution remains stably stored in the hollow inner column storage tank 3, preparing for subsequent dilution and dosing operations. When dilution of the corrosion inhibitor is required, the second liquid-blocking solenoid valve 13 must first be ensured to be in a closed state. Subsequently, the corrosion inhibitor solution will be discharged through the overflow opening 15 and the first solenoid outlet valve 4. The corrosion inhibitor is directed to the corresponding dosing chamber. Since the multiple dosing chambers have equal volumes, the vertical electric guide rail 16 can drive the inner partition displacement ring 11 to slide up and down along the inner wall of the hollow inner column liquid storage chamber 3. When the inner partition displacement ring 11 moves up or down, it changes the liquid space inside the hollow inner column liquid storage chamber 3. When the inner partition displacement ring 11 moves upward, it increases the liquid space connected to the first electromagnetic discharge valve 4 below, thereby regulating the amount of corrosion inhibitor liquid discharged into the dosing chamber. In this way, the dilution ratio of the corrosion inhibitor in multiple dosing chambers can be flexibly adjusted, increasing... The functionality of the hollow inner column storage tank 3 is enhanced. Simultaneously, the sealing side plug 12 outside the inner partition displacement ring 11 effectively improves the sealing performance between the inner partition displacement ring 11 and the inner wall of the hollow inner column storage tank 3, preventing leakage of the corrosion inhibitor solution during liquid space adjustment and ensuring the accuracy and stability of the dilution operation. During the process of the corrosion inhibitor solution entering the dosing chamber and mixing with ordinary water, the motor 9 drives the rotation of the hollow inner column storage tank 3, and the outer agitator fan 6 also rotates at high speed. During the rotation of the outer agitator fan 6, the corrosion inhibitor solution in the dosing chamber... The corrosion inhibitor is vigorously stirred with ordinary water to accelerate the mixing of the two liquids. This mechanical stirring method can significantly improve the dispersion speed and uniformity of the corrosion inhibitor solution in ordinary water, allowing the corrosion inhibitor to be diluted more quickly and thoroughly, thus improving the dilution efficiency of the entire device. This ensures that a corrosion inhibitor diluted solution meeting the concentration requirements can be prepared in a short time. After dilution and mixing, the corrosion inhibitor diluted solution will be transported to the corresponding water treatment system by the liquid outlet pump block 7, realizing the precise addition of the corrosion inhibitor and enabling it to protect metal equipment from corrosion.

[0033] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
