Description

Technical Field

[0001] This utility model relates to the field of demineralized water storage, and in particular to a corrosion-resistant demineralized water storage tank. Background Technology

[0002] Demineralized water, also known as desalinated water or desalinated water, refers to water obtained by removing dissolved minerals and salts from water through various physical and chemical methods. Demineralized water storage tanks are specially designed containers for storing treated water with minerals and salts removed. These storage tanks are widely used in many industries, especially in scenarios requiring high-purity water, such as pharmaceuticals, electronics manufacturing, power industry, chemical industry, and laboratory research.

[0003] Existing demineralized water storage methods typically involve pouring the demineralized water into a storage tank and then sealing it with the lid. However, most existing storage tanks are made of stainless steel or carbon steel. During long-term use, the extremely low conductivity and strong corrosiveness of demineralized water to metal materials can easily cause corrosion to the inner wall of the storage tank, leading to a shortened lifespan of the equipment, water pollution, and affecting the stability of the demineralized water, making it very inconvenient to use.

[0004] Therefore, it is necessary to design a corrosion-resistant demineralized water storage tank that can detect the pH value of the demineralized water while adding alkaline or acidic solutions to adjust the pH value of the demineralized water during storage, reduce corrosion of the inner cylinder, extend the service life of the device, facilitate the maintenance of the stability of the demineralized water, and be easy to use. Utility Model Content

[0005] To overcome the drawbacks of demineralized water's extremely low conductivity and strong corrosiveness to metal materials during long-term use, which easily corrodes the inner wall of the storage tank, shortens the equipment's lifespan, pollutes the water, affects the stability of the demineralized water, and is extremely inconvenient to use, this utility model provides a corrosion-resistant demineralized water storage tank that can detect the pH value of the demineralized water while simultaneously adding alkaline or acidic solutions to adjust the pH value during storage. This reduces corrosion to the inner cylinder, extends the service life of the device, facilitates the maintenance of the stability of the demineralized water, and is convenient to use.

[0006] The technical solution is as follows: A corrosion-resistant demineralized water storage tank includes an outer cylinder, a support, a top cover, a water outlet pipe, a valve, a liquid inlet pipe, an inner cylinder, an adjustment component, and a vacuum component. The outer cylinder is connected to the upper part of the support, and the top cover is snapped onto the upper part of the outer cylinder. The water outlet pipe is connected to the lower left side of the outer cylinder, and a valve is installed on the water outlet pipe. The liquid inlet pipe is connected to the upper side of the middle part of the top cover, and a valve is also installed on the liquid inlet pipe. The inner cylinder is connected to the bottom of the outer cylinder, and the water outlet pipe is connected to the inner cylinder. The top cover is equipped with an adjustment component for adjusting the pH of the demineralized water, and the right side of the top cover is equipped with a vacuum component for extracting oxygen from the inner cylinder.

[0007] Furthermore, the inlet pipe is L-shaped.

[0008] Furthermore, the adjustment assembly includes a liquid storage box, a connecting pipe, a solenoid valve, a liquid pump, and a pH meter. The liquid storage box is connected to the upper sides of both the front and rear parts of the top cover. A connecting pipe is connected between the left sides of the liquid storage box. Solenoid valves are connected to both the front and rear parts of the connecting pipe. A liquid pump is connected to the upper left side of the top cover and is connected to the connecting pipe. A pH meter is connected to the rear right side of the top cover.

[0009] Furthermore, a sealing cap is provided on the upper part of the liquid storage box.

[0010] Furthermore, the vacuum assembly includes a mounting bracket, a vacuum pump, and an air pipe. The right side of the top cover is connected to two mounting brackets, one in front and one behind. The vacuum pump is connected between the mounting brackets, and an air pipe is connected to the front of the vacuum pump. The air pipe is connected to the top cover.

[0011] Furthermore, it also includes a sealing strip, with a sealing strip connected to the lower side of the upper cover, and both the outer and inner cylinders are in contact with the sealing strip.

[0012] Compared with the prior art, the present invention has the following advantages: 1. The present invention detects the pH value of the demineralized water using a pH meter. When the pH value does not meet the preset value, the corresponding solenoid valve is energized and opened, allowing alkaline or acidic solution to flow into the inner cylinder for adjustment. This allows the pH value of the demineralized water to be detected while adding alkaline or acidic solution to adjust and store the pH value of the demineralized water, reducing corrosion of the inner cylinder, extending the service life of the device, facilitating the maintenance of the stability of the demineralized water, and making it convenient to use.

[0013] 2. This utility model introduces demineralized water into the inner cylinder, which is then sealed by a sealing strip. Next, the vacuum pump on the mounting frame is activated to extract air from the inner cylinder through the air pipe, thereby storing the demineralized water. This process of extracting air from the cylinder to store the demineralized water prevents oxidation and contamination of the demineralized water, slows down the oxidation reaction between the demineralized water and the inner cylinder, ensures the quality of the demineralized water, and extends the storage time of the demineralized water.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0020] A corrosion-resistant demineralized water storage tank, such as Figures 1-4 As shown, the device includes an outer cylinder 1, a support 2, a top cover 3, a water outlet pipe 4, a valve 5, an inlet pipe 6, an inner cylinder 7, a sealing strip 8, an adjustment assembly, and a vacuum assembly. The upper part of the support 2 is connected to the outer cylinder 1, and the top cover 3 is snapped onto the upper part of the outer cylinder 1. The water outlet pipe 4 is connected to the lower left side of the outer cylinder 1, and the valve 5 is installed on the water outlet pipe 4. The inlet pipe 6, which is L-shaped, is connected to the upper side of the middle part of the top cover 3, and the valve 5 is also installed on the inlet pipe 6. The inner cylinder 7 is connected to the bottom of the outer cylinder 1, and the water outlet pipe 4 is connected to the inner cylinder 7. The sealing strip 8 is connected to the lower side of the top cover 3. Both the outer cylinder 1 and the inner cylinder 7 are in contact with the sealing strip 8 for easy sealing. The top cover 3 is equipped with an adjustment assembly for adjusting the pH of the demineralized water. The adjustment assembly includes a storage box 9, a connecting pipe 10, and a solenoid valve 1. 01. Liquid pump 11 and pH meter 15. The upper sides of the front and rear parts of the upper cover 3 are connected to the liquid storage box 9. The upper part of the liquid storage box 9 is provided with a sealing cover for easy opening and adding solution. The left side of the liquid storage box 9 is connected to the connecting pipe 10. The front and rear parts of the connecting pipe 10 are connected to the solenoid valve 101. The upper left side of the upper cover 3 is connected to the liquid pump 11. The liquid pump 11 is connected to the connecting pipe 10. The right rear part of the upper cover 3 is connected to the pH meter 15. The right side of the upper cover 3 is provided with a vacuum assembly for extracting oxygen from the inner cylinder 7. The vacuum assembly includes a mounting bracket 12, a vacuum pump 13 and a gas pipe 14. The right side of the upper cover 3 is connected to the front and rear mounting brackets 12. The vacuum pump 13 is connected between the mounting brackets 12. The front side of the vacuum pump 13 is connected to the gas pipe 14 and the gas pipe 14 is connected to the upper cover 3.

[0021] When demineralized water needs to be stored, this device can be used. The support 2 is brought into contact with the ground, and the sealing cap is rotated to remove it. Alkaline and acidic solutions are added to the storage box 9. After adding the appropriate solutions, the sealing cap is then brought into contact with the storage box 9 and rotated for installation. Demineralized water is then connected to the inlet pipe 6 (L-shaped). The valve 5 on the inlet pipe 6 is then turned to open, allowing the demineralized water to enter the inner cylinder 7. The sealing strip 8 is used to seal the inlet. After the appropriate amount of demineralized water has entered, the valve 5 is turned in the opposite direction to close it. The vacuum pump 13 on the mounting bracket 12 is then started, causing air in the inner cylinder 7 to be extracted through the air pipe 14. This creates a vacuum in the inner cylinder 7 for storing the demineralized water, preventing oxidation and contamination, slowing down the oxidation reaction between the demineralized water and the inner cylinder 7, ensuring the quality of the demineralized water, and extending its storage time. The vacuum pump 13 is then turned off, and the demineralized water is then connected to the storage box 9. The pH meter 15 detects the pH value of the desalinated water. When the pH value of the desalinated water does not meet the preset value, the corresponding solenoid valve 101 is energized and opened according to the detection result of the pH meter 15. Then, the liquid pump 11 is started, allowing alkaline or acidic solution to flow into the connecting pipe 10 and then into the desalinated water in the inner cylinder 7, thereby adjusting the pH value of the desalinated water. When the preset value is reached, the liquid pump 11 is turned off, causing the solenoid valve 101 to be de-energized and closed. This allows for the simultaneous detection of the pH value of the desalinated water and the addition of alkaline or acidic solution to adjust and store the pH value, reducing corrosion of the inner cylinder 7, extending the service life of the device, facilitating the maintenance of the stability of the desalinated water, and making it convenient to use. When the desalinated water needs to be used, the valve 5 on the outlet pipe 4 is turned to open, allowing the desalinated water to flow out for use. Then, the valve 5 on the outlet pipe 4 is turned to close. After the desalinated water in the inner cylinder 7 has been used up, the top cover 3 is removed, and the device can then be cleaned.
