[0002] Chemical liquid storage tanks are widely used equipment in the chemical, pharmaceutical, and energy fields for the safe storage of various corrosive, volatile, or highly hazardous chemical liquids. These devices typically include core components such as the tank body, sealing structure, and liquid level monitoring device. Traditional storage tanks often use bolt-tightened flanges or simple cover structures for sealing, relying on manual tightening and the elastic deformation of rubber gaskets to achieve a seal. With long-term use, the seal is prone to failure due to material aging, vibration, or internal pressure fluctuations, posing a risk of leakage and potentially causing safety accidents.

Traditional sealing structures rely on simple magnetic attraction, which can easily lead to problems such as loose sealing caps and insufficient deformation recovery of sealing components under conditions of increased internal pressure or accidental external impact. This can result in media leakage, safety hazards, and seriously affect the reliability of chemical liquid storage tanks. Utility Model Content

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Example

[0014] This utility model provides a chemical liquid storage tank, such as Figures 1 to 5 As shown, the system includes: a tank body 1, a discharge pipe 2, a connector 3, and a sealing assembly. The tank body 1 supports the chemical liquid storage tank. The discharge pipe 2 is connected to the tank body 1 and is equipped with a valve. The connector 3 is connected to the tank body 1 and can be a connecting ring. The sealing assembly includes a magnetic component 4, a sealing component 5, a sealing cap 6, a magnetic component 7, a snap-fit ​​component 8, a movable component 9, and an elastic component 10. The magnetic component 4 is connected to the connector 3. The sealing component 5 is bonded to the magnetic component 4 and can be a fluororubber ring. Fluororubber is highly corrosion-resistant and has high sealing performance. The sealing cap 6 is movably mounted on the connector 3. The magnetic component 7 is connected to the sealing cap 6. The magnetic component 4 and the magnetic component 7... 7 can all be magnets. The snap-fit ​​part 8 is connected to the sealing cover 6. The snap-fit ​​part 8 can be a snap-fit ​​rod. The snap-fit ​​part 8 is movably set on the sealing cover 6. The movable part 9 is movably set on the sealing cover 6. The movable part 9 can be a movable block. The top and bottom of one end of the movable part 9 are both opened with bevels to reduce the friction when in contact with the connecting part 3. The elastic part 10 is connected to the movable part 9. The elastic part 10 can be a spring. The elastic part 10 is connected to the sealing cover 6. The sealing cover 6 drives the snap-fit ​​part 8 to keep it in contact with the sealing part 5. The connecting part 3 is provided with a limiting groove 16. The limiting groove 16 is set one-to-one with the movable part 9. The movable part 9 is provided with a limiting part 17. The limiting part 17 is movably set on the sealing cover 6.

[0015] By combining magnetic sealing with mechanical locking, the sealing cover 6 can be prevented from being accidentally opened due to internal pressure or external vibration, which greatly improves the sealing reliability of the sealing cover 6 and thus significantly improves the reliability of the chemical liquid storage tank.

[0016] When sealing the tank 1, the sealing cap 6 is first aligned and pressed into the connector 3. During the pressing process, the magnetic component 7 on the sealing cap 6 and the magnetic component 4 on the connector 3 gradually approach each other. Since both are magnets, the opposite poles generate a strong magnetic attraction. This force drives the sealing cap 6 to press down tightly. The sealing cap 6 drives the snap-fit ​​component 8 to insert into the sealing component 5, causing the sealing component 5 to undergo elastic deformation, thereby effectively filling the gap between the sealing component 5 and the connector 3, thus effectively forming a sealing layer. During the pressing process of the sealing cap 6, the inclined surface of the movable component 9 of the sealing cap 6 comes into contact with the connector 3 and is squeezed, causing the connector 3 to squeeze the elastic component 10 inward. When the movable component 9 moves to the position of the limiting groove 16, since the movable component 9 is no longer squeezed by the connector 3, the compressed elastic component 10 releases its elasticity, pushing the movable component 9 to pop out quickly and snap into the limiting groove 16. The limiting component 17 on the movable component 9 ensures the stability of its movement. At this time, the movable component 9 and the limiting groove 16 engage to lock the sealing cap 6.

[0017] Specifically, a discharge pipe 2 is connected to the top of the tank body 1, a connector 3 is fixedly connected to the top of the tank body 1, a magnetic component 4 is fixedly connected to the bottom of the connector 3, a sealing component 5 is bonded to the inner surface of the magnetic component 4, a sealing cover 6 is movably connected inside the connector 3, a magnetic component 7 is fixedly connected to the bottom of the sealing cover 6, a snap-fit ​​component 8 is fixedly connected to the bottom of the sealing cover 6 inside the magnetic component 7, the outer surface of the snap-fit ​​component 8 is movably connected to the inner surface of the sealing component 5, two movable components 9 are movably connected inside the sealing cover 6, an elastic component 10 is fixedly connected to one end of the movable component 9, one end of the elastic component 10 is fixedly connected to the inside of the sealing cover 6, and limit components 17 are fixedly connected to both ends of the movable component 9, the outer surface of the limit component 17 is movably connected to the inside of the sealing cover 6, and a limit groove 16 is opened inside the connector 3 at the position corresponding to the movable component 9, the outer surface of the movable component 9 is snapped into the inside of the limit groove 16.

[0018] To achieve an intuitive and reliable method for monitoring the liquid level in tank 1, such as... Figures 1 to 5As shown, it also includes an observation assembly, which includes a first connecting pipe 11, an observation pipe 12, a second connecting pipe 13, a protective component 14, and a connecting plate 15. The first connecting pipe 11 is connected to the tank body 1, the observation pipe 12 is connected to the first connecting pipe 11, and the second connecting pipe 13 is connected to the observation pipe 12. The observation pipe 12 can be a high-strength transparent glass tube. The observation pipe 12 is kept horizontal. The top and bottom ends of the observation pipe 12 are protected against impacts relative to the protruding part of the protective component 14. The second connecting pipe 13 is connected to the tank body 1 and provides protection against impacts. The protective component 14 is fitted onto the observation tube 12. The protective component 14 can be a protective sleeve. An observation groove is provided on the protective component 14. The connecting plate 15 is connected to the protective component 14 and the tank body 1. The protective component 14 is located outside the observation tube 12. The center of the protective component 14 and the center of the observation tube 12 are on the same vertical line. The first connecting pipe 11 is located below the observation tube 12, and the second connecting pipe 13 is located above the observation tube 12. The observation tube 12 is sandwiched between the first connecting pipe 11 and the second connecting pipe 13.

[0019] By using the observation components, a direct and reliable liquid level monitoring method can be achieved for tank 1. Furthermore, the observation tube 12 can be protected, which not only avoids the risk of liquid leakage and personal injury caused by the rupture of the observation tube 12, but also effectively improves the safety of the observation tube 12 and extends its service life, thereby significantly improving the user experience of the chemical liquid storage tank.

[0020] In use, the observation component is connected to the top and bottom of the tank 1 through connecting pipe 11 and connecting pipe 13 respectively, thus forming a continuous loop with the observation tube 12. According to the principle of communicating vessels, under the static pressure balance of the internal liquid, the liquid level inside the observation tube 12 is always consistent with the actual liquid level inside the tank 1. Since the observation tube 12 is made of high-strength transparent glass, the operator can directly and accurately observe the real-time liquid level inside the tank through the observation groove on the protective part 14. The protective part 14, which is fitted over the observation tube 12, plays a key protective role and can effectively prevent external objects from colliding with and damaging the observation tube 12.

[0021] Specifically, the bottom of the tank body 1 is connected to a connecting pipe 11, one end of the connecting pipe 11 is connected to an observation pipe 12, the top of the observation pipe 12 is connected to a connecting pipe 13, one end of the connecting pipe 13 is connected to the top of the tank body 1, a protective component 14 is provided on the outside of the observation pipe 12, one end of the protective component 14 is fixedly connected to a connecting plate 15, and one end of the connecting plate 15 is fixedly connected to the outer surface of the tank body 1.

[0022] Working Principle: In actual use, when sealing the tank 1 is required, the sealing cap 6 is first aligned and pressed into the connector 3. During the pressing process, the magnetic component 7 on the sealing cap 6 and the magnetic component 4 on the connector 3 gradually approach each other. Since both are magnets, their opposite poles generate a strong magnetic attraction. This force drives the sealing cap 6 to press down tightly. The sealing cap 6 drives the snap-fit ​​component 8 to insert into the sealing component 5, causing the sealing component 5 to undergo elastic deformation, thereby effectively filling the gap between the sealing component 5 and the connector 3, thus effectively forming a sealing layer. During the pressing process of the sealing cap 6, the inclined surface of the movable component 9 driven by the sealing cap 6 comes into contact with and is squeezed by the connector 3. This causes the connecting piece 3 to compress the elastic element 10 inward. When the movable part 9 moves to the position of the limiting groove 16, since the movable part 9 is no longer compressed by the connecting piece 3, the compressed elastic element 10 releases its elastic force, pushing the movable part 9 to quickly pop out and lock into the limiting groove 16. The limiting element 17 on the movable part 9 ensures the stability of its movement. At this time, the movable part 9 and the limiting groove 16 engage to lock the sealing cover 6. The combination of magnetic sealing and mechanical locking can prevent the sealing cover 6 from being accidentally opened due to internal pressure or external vibration, greatly improving the sealing reliability of the sealing cover 6, thereby significantly improving the reliability of the chemical liquid storage tank. Then, since the observation component is connected to the top and bottom of the tank 1 through connecting pipe 11 and connecting pipe 13 respectively, it forms a continuous loop with the observation tube 12. According to the principle of communicating vessels, under the static pressure balance of the internal liquid, the liquid level inside the observation tube 12 is always consistent with the actual liquid level inside the tank 1. Since the observation tube 12 is made of high-strength transparent glass, the operator can intuitively and accurately observe the real-time liquid level inside the tank through the observation groove on the protective part 14. The protective part 14, which is fitted outside the observation tube 12, plays a key protective role and can effectively prevent external objects from colliding with and damaging the observation tube 12. It can realize an intuitive and reliable liquid level monitoring method for the tank 1, and can protect the observation tube 12. This not only avoids the risk of liquid leakage and personal injury caused by the rupture of the observation tube 12, but also effectively improves the safety of the observation tube 12 and extends its service life, thereby significantly improving the user experience of the chemical liquid storage tank.

[0023] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
