[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] Example 1

[0028] As attached Figure 1 —Attachment Figure 5 As shown, a storage and protection device for an organic solvent includes a storage tank 1, a protective base 2 is sleeved on the outer side of the bottom of the storage tank 1, a protective outer cover 3 is threadedly mounted on the outer side of the top of the storage tank 1, and a sealing inner cover 4 is slidably mounted inside the protective outer cover 3;

[0029] Multiple groups of springs 7 are connected between the top of the sealed inner cover 4 and the top of the protective outer cover 3. A through hole 8 is provided at the center of the top of the protective outer cover 3. A shift rod 9 is rotatably connected inside the through hole 8. A mounting cross bar 10 passes through the lower end of the shift rod 9. Multiple groups of rollers 11 are rotatably installed on the outer side of the mounting cross bar 10. A handle 12 passes through the upper end of the shift rod 9. A limiting mechanism that cooperates with the handle 12 is installed on the upper side of the protective outer cover 3.

[0030] With the above structure, after the volatile organic solvent is placed inside the storage tank 1, the storage tank 1 is placed inside the protective base 2. The protective base 2 ensures the stability of the storage tank 1. The protective outer cover 3 is threadedly installed on the outside of the top of the storage tank 1. The sealed inner cover 4 is sleeved on the outside of the tank opening of the storage tank 1. The handle 12 is held to rotate the upper end of the lever 9 upward. The lower end of the lever 9 drives the installation cross bar 10 and the multiple sets of rollers 11 rotatably installed on the outer side to move downward. The multiple sets of rollers 11 press on the upper side of the sealed inner cover 4, pressing the sealed inner cover 4 against the outside of the tank opening of the storage tank 1 to seal it. The handle 12 is positioned by a limit mechanism to prevent the lever 9 from rotating. The specific structure is as follows:

[0031] Combined with attachment Figure 4 and attached Figure 6As shown, the limiting mechanism includes a support frame 13, and a U-shaped frame 15 is embedded on the inner side of the top of the support frame 13 to cooperate with the handle 12 to be inserted. A limiting pin 16 slides through the two side walls of the U-shaped frame 15. The U-shaped frame 15 is a horizontal structure and the slot is away from the support frame 13.

[0032] Multiple groups of springs 7 are respectively installed at the top edge of the sealing inner cover 4.

[0033] Through the above structure, the handle 12 is rotated to the inside of the U-shaped frame 15, and the limiting pin 16 passes through the upper and lower side walls of the U-shaped frame 15 to limit the handle 12 inside the U-shaped frame 15 to prevent the handle 12 from detaching from the inside of the U-shaped frame 15.

[0034] The multiple sets of springs 7 are respectively installed at the top edge of the sealed inner cover 4, which will not affect the sliding of the multiple sets of rollers 11 on the upper side of the sealed inner cover 4.

[0035] Combined with attachment Figure 7 As shown, a plug 5 is installed on the inner wall of the top of the sealed inner cover 4, and the plug 5 is inserted into the inside of the tank mouth of the preservation tank 1. A sealing gasket 6 is installed between the inner wall of the sealed inner cover 4 and the outer side of the plug 5.

[0036] Through the above structure, the plug 5 is inserted into the mouth of the preservation tank 1 to position the sealing inner cover 4, and is wrapped with the mouth of the preservation tank 1 through the sealing gasket 6. When the sealing inner cover 4 is pressed tightly against the mouth of the preservation tank 1, the sealing gasket 6 plays a sealing role.

[0037] Example 2

[0038] Based on the first embodiment, please refer to the attached Figure 4 and attached Figure 7 An air pressure sensor 17 is installed on the lower side of the block 5, and an air guide tube 19 passes through the eccentric side of the block 5. The upper end of the air guide tube 19 slides out of the protective outer cover 3, and a sealing valve 14 is installed on the air guide tube 19. A controller 18 connected to the air pressure sensor 17 and the sealing valve 14 is installed on the upper side of the protective outer cover 3.

[0039] With the above-described structure of Example 2, after the preservation tank 1 is sealed, the air pressure state inside the preservation tank 1 is monitored in real time by the air pressure sensor 17, and the data is promptly transmitted to the controller 18. The controller 18 analyzes and processes the data. When the air pressure is high, the controller 18 opens the sealing valve 14 and guides air through the air guide tube 19 to balance the air pressure inside the preservation tank 1. When the air pressure reaches a safe value, the controller 18 immediately closes the sealing valve 14 to prevent the organic solvent from evaporating from the air guide tube 19.
