[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Embodiment 1: This embodiment is used to solve the problem that during the use of chemical storage tanks in the prior art, their interfaces are usually connected using flanges and sealed by sealing rings. However, after long-term use, the sealing rings are easily damaged by the corrosion of chemical liquids, resulting in leakage at the interfaces and difficulty in ensuring the sealing of the interfaces.

[0025] See also Figure 1 - Figure 3 As shown, this embodiment is a chemical storage tank interface sealing device, including a fixed block 1 and a tank body 2, on which a liquid inlet pipe 201 is fixedly installed. The liquid inlet pipe 201 is fixedly connected to a connecting pipe 203 through a flange 202, and the flange 202 is located in the fixed block 1.

[0026] A sealing assembly 3 is movably installed inside the fixed block 1. The sealing assembly 3 includes a sealing block 301 and a movable plate 302. The sealing block 301 is fixedly installed in the fixed block 1, and the connection between the sealing block 301 and the flange 202 is abutted. The movable plate 302 is movably installed in the fixed block 1, and the movable plate 302 is located on both sides of the flange 202. The fixed block 1 is composed of a shell 1 304 and a shell 2 305 fixedly connected. It adopts a split design to facilitate subsequent maintenance and replacement. There are multiple movable plates 302. A connecting block 1 306 is fixedly installed on the shell 1 304, and a limiting hole 307 is provided on the connecting block 1 306.

[0027] A connecting block 2 308 is fixedly installed on the shell 2 305, and a limiting rod 309 is fixedly installed on the connecting block 2 308. The position of the limiting rod 309 is adapted to the limiting hole 307. A connecting block 310 is fixedly installed on the connecting block 1 306. A plug rod 311 is movably installed in the connecting block 310. A reset block 312 is fixedly installed on the plug rod 311. The reset block 312 is movably installed in the connecting block 310. A spring is fixedly installed on the reset block 312, and one end of the spring is fixedly connected to the connecting block 1 306.

[0028] A locking hole 313 is provided on the limiting rod 309, and the bottom of the insertion rod 311 passes through the connecting block 1 306. The bottom of the insertion rod 311 is fixedly connected to the locking hole 313. In actual use, the insertion rod 311 is pulled to compress the spring. At this time, the limiting rod 309 is inserted into the limiting hole 307, and the connecting block 1 306 and the connecting block 2 308 fit together. At this time, the insertion rod 311 is released, and the insertion rod 311 is reset under the action of the spring, thereby driving one end of the insertion rod 311 to be inserted into the locking hole 313.

[0029] An adjusting bolt 314 is movably installed on both the shell 1 304 and the shell 2 305 through a thread, and one end of the adjusting bolt 314 is movably connected to the movable plate 302. In actual use, by turning the adjusting bolt 314, the movable plate 302 is pushed toward the flange 202 under the action of the thread until the movable plate 302 is in contact with the flange 202.

[0030] That is, during actual use, the sealing block 301 is used to squeeze the connection of the flange 202 to ensure the sealing of the connection, and at the same time, the movable plate 302 is driven to move toward the flange 202 until the movable plates 302 on both sides are against the flange 202, and the movable plate 302 is used to apply pressure to the flange 202, thereby ensuring the tightness of the connection and further improving the sealing of the connection.

[0031] Embodiment 2: This embodiment is used to solve the problem that when chemical liquid leaks, the chemical liquid drips directly from the interface, easily polluting the surrounding environment and creating a safety hazard.

[0032] See also Figure 4 - Figure 5 As shown, the utility model also includes a collecting barrel 303, which is fixedly installed at the bottom of the fixed block 1, wherein the collecting barrel 303 is made of transparent material. When the chemical liquid enters the collecting barrel 303, it can be visually detected from the outside whether there is any chemical liquid leakage, which is very convenient and practical.

[0033] That is, when leakage occurs, the chemical liquid, under the guidance of the sealing block 301, extends the arc-shaped sealing block 301 and flows toward the bottom of the fixed block 1. The chemical liquid is collected by the collection barrel 303 to prevent it from dripping directly into the environment, which greatly improves safety. At the same time, the chemical liquid is collected uniformly for easy subsequent processing.

[0034] In combination with Example 1 and Example 2, the connection of the flange 202 is squeezed by the sealing block 301 to ensure the sealing of the connection, and at the same time, the movable plate 302 is driven to move toward the flange 202 until the movable plates 302 on both sides are against the flange 202. The movable plate 302 is used to apply pressure to the flange 202 to ensure the tightness of the connection, further improve the sealing of the connection, and collect the chemical liquid through the collection barrel 303 to prevent it from dripping directly into the environment, thereby greatly improving safety. At the same time, the chemical liquid is collected in a unified manner to facilitate subsequent processing.

[0035] The working process and principle of this utility model are as follows:

[0036] First, the sealing block 301 squeezes the flange 202 connection to ensure the sealing of the connection, and at the same time drives the movable plate 302 to move toward the flange 202 until the movable plates 302 on both sides abut against the flange 202. The movable plates 302 apply pressure to the flange 202 to ensure the tightness of the connection and further improve the sealing of the connection;

[0037] Furthermore, the chemical liquid is collected by the collection barrel 303 to prevent it from dripping directly into the environment, which greatly improves safety. At the same time, the chemical liquid is collected uniformly for subsequent processing.

[0038] In summary, the sealing assembly 3 provided in the present invention not only improves the sealing performance of the connection, but also greatly improves the safety of the chemical storage tank during use.
