[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 , Figure 2 and Figure 4 It is understood that this utility model provides a technical solution: a chemical liquid storage device, including a storage tank 1, a feed pipe 2, a cover 3, a discharge control valve 4, and a safety valve 5. The top of the storage tank 1 is connected to the feed pipe 2, and the top of the feed pipe 2 is threadedly connected to the cover 3. The bottom of the storage tank 1 is installed on the outer side of the bottom, and the top of the storage tank 1 away from the cover 3 is installed with the safety valve 5. The outer side of the storage tank 1 is connected to a connecting frame 6, and a sealing ring 7 is bonded inside the connecting frame 6. The top of the sealing ring 7 has an annular groove 8. The outer side of the connecting frame 6 near the cover 3 is connected to a first connecting shaft 9, and the outer side of the first connecting shaft 9 is rotatably connected to a threaded post 10. The outer side of the threaded post 10 is threadedly connected to a threaded ring 11.

[0022] This chemical liquid storage device has a stainless steel storage tank 1, and a safety valve 5 to ensure the safety and stability of the storage process.

[0023] exist Figures 1-3 In the middle: the outer side of the connecting frame 6 away from the first connecting shaft 9 is connected to the second connecting shaft 12, the outer side of the second connecting shaft 12 is rotatably connected to the connecting block 13, the end of the connecting block 13 is connected to the sealing cover 14, and the outer side of the sealing cover 14 away from the connecting block 13 is connected to the U-shaped block 15.

[0024] The sealing cap 14 of this chemical liquid storage device can further improve the sealing performance of the storage device.

[0025] exist Figures 1-3 In the middle: the inner wall dimension of the U-shaped block 15 is larger than the outer diameter dimension of the threaded column 10, and the shape of the connecting block 13 is L-shaped.

[0026] In this chemical liquid storage device, the threaded column 10 and the U-shaped block 15 form a sliding structure.

[0027] In practice, the chemical liquid storage device is prone to volatilization and hydrolysis of methyltrimethoxysilane inside the storage tank 1 due to the loose fixing of the cover 3, which affects its subsequent normal use. After fixing the cover 3 to the top of the feed pipe 2 by means of threaded connection, the sealing cover 14 can be pushed towards the top of the storage tank 1. When the sealing cover 14 moves, it can drive the connecting block 13 and the U-shaped block 15 to move. When the connecting block 13 moves, it can be rotated through the second connecting shaft 12, so that the sealing cover 14 can be flipped. When the sealing cover 14 is flipped and moved to the top of the storage tank 1, the bottom end of the sealing cover 14 can be inserted into the annular groove 8. At this time, the threaded column 10 can be pulled towards the U-shaped block 15. When the threaded column 10 moves, it can be rotated through the first connecting shaft 9. When the threaded column 10 rotates to the inside of the U-shaped block 15, the threaded ring 11 can be tightened, so that the threaded ring 11 can press and fix the surface of the U-shaped block 15. At the same time, the bottom end of the sealing cover 14 can be pressed into the annular groove 8.

[0028] See Figures 1-3 It can be seen that the sealing effect of the storage device can be improved by the sealing cover 14 and the sealing ring 7, so that the methyltrimethoxysilane inside the storage tank 1 is less likely to volatilize and hydrolyze due to insufficient connection between the cover 3 and the feed pipe 2.

[0029] exist Figure 1 , Figure 4 and Figure 5 In the middle: The storage tank 1 is connected to the top of the cover 3 with a first connecting post 16 and a second connecting post 17 respectively. A rotating block 18 is slidably connected to the outside of the first connecting post 16. A connecting cylinder 19 is connected to the end of the rotating block 18. A filter screen 20 is connected inside the connecting cylinder 19.

[0030] The chemical liquid storage device has a filter screen 20 that can improve the purity of the chemical liquid.

[0031] exist Figure 1 , Figure 4 and Figure 5 In the middle: a connecting plate 21 is connected to the outside of the connecting cylinder 19. A U-shaped groove 22 is opened inside the connecting plate 21. A threaded knob 23 is threadedly connected to the outside of the connecting plate 21. A threaded hole is opened on the outside of the second connecting column 17 near the threaded knob 23.

[0032] The chemical liquid storage device allows the connecting plate 21 to be moved to the outside of the second connecting column 17 via the U-shaped groove 22.

[0033] In practical implementation, before using the chemical liquid storage device, methyltrimethoxysilane needs to be filled into the storage tank 1. Since catalyst particles or unreacted substances may remain in the methyltrimethoxysilane during production, traditional storage devices struggle to filter them. After opening the cover 3, the connecting cylinder 19 can be pulled upwards. As the connecting cylinder 19 moves, it drives the rotating block 18 and the connecting plate 21 to move. When the connecting cylinder 19 rises to a designated height, the connecting plate 21 can be pushed towards the second connecting column 17. At this time, the rotating block 18 can enter through the first connecting column 16. The connecting cylinder 19 is rotated so that it can be moved to the top of the feed pipe 2, and the connecting plate 21 can be moved to the outside of the second connecting post 17 through the U-shaped groove 22. At this time, the connecting cylinder 19 is released so that the bottom end of the connecting cylinder 19 can fall into the feed pipe 2 due to gravity, so that the filter screen 20 is located inside the feed pipe 2. The bottom of the rotating block 18 and the connecting plate 21 can fall on the top surface of the feed pipe 2, and the threaded knob 23 is tightened so that the threaded knob 23 can slide into the threaded hole of the second connecting post 17, thereby fixing the position of the connecting cylinder 19. At this time, the filling operation can be carried out.

[0034] See Figure 1 , Figure 4 and Figure 5 It can be seen that the filter screen 20 inside the connecting cylinder 19 can directly filter the particles or unreacted substances in methyltrimethoxysilane, so that the purity of methyltrimethoxysilane inside the storage tank 1 is high.

[0035] In summary, when using this chemical liquid storage device, the sealing cap 14 can be pushed towards the top of the storage tank 1. When the sealing cap 14 moves, it can drive the connecting block 13 and the U-shaped block 15 to move. When the connecting block 13 moves, it can rotate through the second connecting shaft 12. The sealing effect of the storage device can be improved by the sealing cap 14 and the sealing ring 7, so that the methyltrimethoxysilane inside the storage tank 1 is not prone to volatilization and hydrolysis due to insufficient connection between the cap 3 and the feed pipe 2. The filter screen 20 inside the connecting cylinder 19 can directly filter the particles or unreacted substances in the methyltrimethoxysilane, so that the purity of the methyltrimethoxysilane inside the storage tank 1 is high. The contents not described in detail in this description are prior art known to those skilled in the art.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
