[0002] A high-purity nitric acid storage device is a specialized piece of equipment used for the safe storage of high-purity nitric acid. It is designed to prevent nitric acid leakage, volatilization, and adverse reactions with the external environment. It is an important piece of industrial equipment that plays a vital role in ensuring the purity of nitric acid, improving storage safety, and meeting the production needs of specific industries.

[0003] The top of the existing storage device needs to be reinforced. However, due to the strong corrosiveness of high-purity nitric acid, corrosion of the top surface is likely to occur when the high-purity nitric acid is transported into the device, which will corrode the structure that fixes the protective plate and affect the stability of the protective plate installation. Therefore, a high-purity nitric acid storage device is needed to more stably fix the protective plate in the required position and prevent the protective plate from falling from a height and causing a safety accident. Utility Model Content

[0004] The purpose of this invention is to provide a high-purity nitric acid storage device to solve the problem mentioned in the background art, where the top of the existing storage device needs to be reinforced, but due to the strong corrosiveness of high-purity nitric acid, corrosion of the top surface is likely to occur when high-purity nitric acid is transported into the device, resulting in corrosion of the structure of the fixed protective plate, thereby affecting the installation stability of the protective plate.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a high-purity nitric acid storage device, comprising:

[0007] Nitric acid storage tank;

[0008] The protective assembly includes a first protective plate, a second protective plate, a fixing post, and a protective tube. The first and second protective plates are laid on the upper surface of the nitric acid storage tank, with the first protective plate located inside the second protective plate. The fixing post is fixed to the upper surface of the nitric acid storage tank and is connected through the interior of the first and second protective plates. The protective tube is threadedly connected to the interior of the first and second protective plates.

[0009] Furthermore, a connecting shaft is fixed inside the top of the fixed column, and a rotating column is rotatably connected to the outer surface of the connecting shaft.

[0010] Furthermore, a magnet is embedded inside the rotating column, and the magnet is also embedded inside the first protective plate and the second protective plate.

[0011] Furthermore, a guide plate is fixed to the upper surface of the protective tube, and the side view of the guide plate is convex.

[0012] Furthermore, it also includes a limiting component, which includes a first fixing plate, a second fixing plate, a connecting plate, and a connecting post; the first fixing plate is fixed to the upper surface of the first protective plate, the second fixing plate is fixed to the upper surface of the second protective plate, the connecting plate is attached to the outer surface of the second fixing plate, the connecting post is fixed to the outer surface of the connecting plate, and the connecting post penetrates and connects the first fixing plate and the interior of the second fixing plate.

[0013] Furthermore, a support plate is fixed to the outer surface of the connecting plate, and an installation groove is provided inside the support plate.

[0014] Furthermore, a spring is fixed inside the mounting groove, and a limit post is fixed on the lower surface of the spring, with the limit post located inside the connecting post.

[0015] Furthermore, a connecting rod is fixed to the upper surface of the limiting post, a connecting block is fixed to the upper surface of the connecting rod, and the lower surface of the connecting block is in contact with the support plate.

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] I. This utility model, through its protective components, allows for the following mechanism: When a damaged first or second protective plate needs to be repaired, a rotational force is applied to the guide plate to remove the protective tube from inside the first or second protective plate. A rotational force is then applied to the rotating column, which is aligned horizontally with the fixed column. This applies an upward lifting force to the first or second protective plate. A new first or second protective plate is then passed through the fixed column and placed in the desired position. Under the action of the connecting shaft, a downward flipping force is applied to the connecting shaft. After the two sets of magnets are connected, the protective tube is then rotated back into the first or second protective plate. This design more stably fixes the protective plate in the desired position, preventing it from falling from a height and causing a safety accident.

[0018] Second, based on the first beneficial effect, when the first and second protective plates need to be separated with the help of the limiting components, an upward force is applied to the connecting block, which drives the connecting rod to apply an upward force. The limiting post retracts into the mounting groove. After the connecting post is no longer restricted, a pulling force is applied to the connecting plate to pull the connecting post out from inside the first and second fixed plates. This solution can not only quickly separate the first and second protective plates, but also make the first and second protective plates stably connected together. Attached Figure Description

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0032] Please see Figures 1-4 As shown, this embodiment is a high-purity nitric acid storage device, comprising:

[0033] Nitric acid storage tank 11;

[0034] The protective assembly includes a first protective plate 21, a second protective plate 22, a fixing post 23, and a protective tube 27. The first protective plate 21 and the second protective plate 22 are laid on the upper surface of the nitric acid storage tank 11, with the first protective plate 21 located inside the second protective plate 22. The fixing post 23 is fixed to the upper surface of the nitric acid storage tank 11 and is connected through the interior of the first protective plate 21 and the second protective plate 22. The protective tube 27 is threadedly connected to the interior of the first protective plate 21 and the second protective plate 22.

[0035] The nitric acid storage tank 11 serves as the main container for high-purity nitric acid. The first protective plate 21 and the second protective plate 22 provide additional protective layers for the nitric acid storage tank 11. The fixing column 23 is used to install the first protective plate 21 and the second protective plate 22 in the required position. The protective tube 27 is used to protect the fixing column 23, thereby making the first protective plate 21 and the second protective plate 22 more stably fixed in the required position.

[0036] A connecting shaft 24 is fixed inside the top of the fixed column 23, and a rotating column 25 is rotatably connected to the outer surface of the connecting shaft 24.

[0037] The connecting shaft 24 is used to rotate the rotating column 25 on its surface. By changing the state of the rotating column 25, the first protective plate 21 or the second protective plate 22 can be restricted to the desired position.

[0038] A magnet 26 is embedded inside the rotating column 25, and the magnet 26 is also embedded inside the first protective plate 21 and the second protective plate 22.

[0039] The magnet block 26 is used to fix the rotating column 25 in the desired position.

[0040] A guide plate 28 is fixed on the upper surface of the protective tube 27, and the side view of the guide plate 28 is convex.

[0041] The guide plate 28 not only facilitates the application of rotational force to the protective tube 27, but also more stably restricts the rotating column 25 to the desired position.

[0042] Working principle: When it is necessary to repair the damaged first protective plate 21 or second protective plate 22, apply a rotational force to the guide plate 28 to remove the protective tube 27 from inside the first protective plate 21 or second protective plate 22. Apply a rotational force to the rotating column 25. The rotating column 25 and the fixed column 23 are on the same horizontal line. Apply an upward lifting force to the first protective plate 21 or second protective plate 22. Then, pass the new first protective plate 21 or second protective plate 22 through the fixed column 23 and place it in the required position. Under the action of the connecting shaft 24, apply a downward flipping force to the connecting shaft 24. After the two sets of magnet blocks 26 are connected together, the protective tube 27 is rotated into the first protective plate 21 or second protective plate 22.

[0043] This step more stably fixes the protective plate in the required position, preventing it from falling from a height and causing a safety accident.

[0044] Please see Figures 1-3 , Figure 5 As shown, this embodiment, based on the above embodiment, further includes a limiting component. The limiting component includes a first fixing plate 31, a second fixing plate 32, a connecting plate 33, and a connecting post 34. The first fixing plate 31 is fixed to the upper surface of the first protective plate 21, the second fixing plate 32 is fixed to the upper surface of the second protective plate 22, the connecting plate 33 is attached to the outer surface of the second fixing plate 32, and the connecting post 34 is fixed to the outer surface of the connecting plate 33. The connecting post 34 penetrates and connects the first fixing plate 31 and the interior of the second fixing plate 32.

[0045] The connecting post 34 is used to connect the first fixing plate 31 and the second fixing plate 32 together, and the connecting plate 33 facilitates the application of a pulling force to the connecting post 34. The first fixing plate 31 and the second fixing plate 32 are used to connect the first protective plate 21 and the second protective plate 22 together.

[0046] A support plate 35 is fixed to the outer surface of the connecting plate 33, and an installation groove 36 is provided inside the support plate 35.

[0047] The support plate 35 is used to limit the movement of the post 38 inside it, and the mounting groove 36 is used to receive and install the spring 37.

[0048] A spring 37 is fixed inside the mounting groove 36, and a limit post 38 is fixed on the lower surface of the spring 37. The limit post 38 is located inside the connecting post 34.

[0049] Spring 37 is used to change the position of limiting post 38, which in turn is used to restrict connecting post 34 inside the first fixing plate 31 and the second fixing plate 32.

[0050] A connecting rod 39 is fixed to the upper surface of the limiting post 38, and a connecting block 391 is fixed to the upper surface of the connecting rod 39. The lower surface of the connecting block 391 is in contact with the support plate 35.

[0051] The connecting rod 39 facilitates changing the position of the limiting post 38, and the connecting block 391 not only facilitates changing the height of the connecting rod 39, but also keeps the mounting groove 36 in a closed state, thereby better protecting the spring 37 and the limiting post 38.

[0052] Working principle: When it is necessary to separate the first protective plate 21 and the second protective plate 22, an upward force is applied to the connecting block 391, which drives the connecting rod 39 to apply an upward force. The limiting post 38 retracts into the mounting groove 36. After the connecting post 34 is no longer restricted, a pulling force is applied to the connecting plate 33 to pull the connecting post 34 out from the first fixing plate 31 and the second fixing plate 32.

[0053] This step not only allows the first protective plate 21 to be quickly separated from the second protective plate 22, but also allows the first protective plate 21 to be stably connected to the second protective plate 22.
