Description

Technical Field

[0001] The invention relates to the technical field of sealed storage, in particular to a moisture-proof storage device for sodium methoxide. Background Art

[0002] Sodium methoxide is an organic compound, a hazardous chemical, corrosive and pyrophoric. It is mainly used in the pharmaceutical industry, as a condensation agent, chemical reagent, catalyst for edible oil treatment in organic synthesis, etc. Pure sodium methoxide is a white solid powder, so it needs to be placed in a dedicated sealed container when stored, and the storage environment must be kept dry, and the air content in the sodium methoxide storage cavity must be reduced as much as possible.

[0003] The sodium methoxide storage device in the prior art realizes the storage function through a storage tank. However, since the capacity of the sodium methoxide stored each time is not consistent, when the stored sodium methoxide cannot completely fill the storage tank, even if the top opening is closed after the storage is completed, since a large amount of residual space still remains inside, the residual air will still cause a small amount of sodium methoxide to decompose during the subsequent storage process, so the moisture-proof performance is not good. On the other hand, when storing multiple tanks, each tank needs to be opened manually in turn, filled and then closed, resulting in extremely cumbersome steps when using multiple storage devices.

The storage process of sodium methoxide is realized by multiple independent storage tanks 1 in the moisture-proof storage device of sodium methoxide. When storing, sodium methoxide is directly put into the interior of the feeding mechanism 8 from one end of the top feeding mechanism 8, and it can automatically fall into the bottom along the interior of the feeding mechanism 8. The independent storage tanks 1 in this embodiment are arranged in three groups. When the frontmost independent storage tank 1 is filled during the feeding process, sodium methoxide will automatically enter the interior of the second group of independent storage tanks 1 in the middle until the entire feeding process is completed. After the feeding is completed, the independent storage tank 1 that is not filled drives the tray 29 inside the independent storage tank 1 to move up by controlling the external cylinder 4, so that the cavity air caused by the internal unfilled can be discharged.

[0028] In this embodiment, a tray 29 is installed inside the independent storage tank 1, and a telescopic tube 30 is connected to the bottom of the middle of the tray 29, and the top and bottom of the telescopic tube 30 are both in an open state. A connecting hole 31 is opened on the surface of the independent storage tank 1, and the interior of the drying box 5 is filled with a desiccant. The diversion pipeline 7 is connected to the interior of the independent storage tank 1 through the connecting hole 31, and the bottom of the telescopic tube 30 is inserted into the interior of the independent discharge pipeline 19. The side of the tray 29 is fitted with the inner wall of the independent storage tank 1 through a mounted sealing gasket, and multiple independent storage tanks 1 are combined. , and are uniformly connected to the feeding mechanism 8 at the top and connected to the discharging mechanism 9 at the bottom. Therefore, when a large amount of sodium methoxide is added, each independent storage tank 1 can be filled in sequence along the inclined feeding channel 12, and the independent sealing structure makes the addition and discharging process simpler and more convenient. Specifically, since the feeding mechanism 8 is in an inclined state as a whole, after the sodium methoxide is added, it slides along the feeding mechanism 8 and moves to the top of the front independent storage tank 1. Then, it can enter the interior of the independent storage tank 1 through the top docking pipe and be supported by the tray 29.

[0029] In this embodiment, the elastic layer 10 includes a top butt joint tube 20 and a bottom butt joint tube 27, the surface of the bottom butt joint tube 27 is provided with a bottom retaining ring 28, the surface of the bottom retaining ring 28 is connected with a spring 26, the surface of the top butt joint tube 20 is provided with a top retaining ring 24, the top of the spring 26 is fixedly connected to the top retaining ring 24, a metal hose 25 is installed between the top butt joint tube 20 and the bottom butt joint tube 27, and the metal hose 25 passes through the middle position of the spring 26, and an elastic layer 10 is provided on the top of each independent storage tank 1, through which the elastic layer 10 can be used in the above-mentioned process of discharging the residual air in the storage cavity to avoid the situation where the first filter membrane 22 is partially damaged due to excessive upward thrust applied by the tray 29. , it provides a protection effect for the exhaust component 11, and at the same time, it is also possible to obtain information on whether the internal air is completely exhausted by observing the vibration of the elastic layer 10. Specifically, when one of the independent storage tanks 1 is not filled, the external air is filled into the space below the tray 29 inside the independent storage tank 1 through the above-mentioned cylinder 4, and the tray 29 can be moved up with the help of air pressure, and the sodium methoxide accumulated on the top is driven to move up until the sodium methoxide moves up and abuts against the sealing column 17 in the feeding mechanism 8. When the tray 29 moves up, the remaining air on the top is discharged from the exhaust pipe 21. At this time, due to the squeezing of sodium methoxide, it will act on the metal hose 25, and then the metal hose 25 will vibrate, thereby preventing the filter membrane from being damaged due to excessive pressure from sodium methoxide.

[0030] In this embodiment, the exhaust assembly 11 includes an exhaust pipe 21, a first filter membrane 22 and a second filter membrane 23. The exhaust assembly 11 is installed on the side of the top butt joint pipe 20, and one end of the exhaust pipe 21 is connected to the inside of the top butt joint pipe 20, and the other end of the exhaust pipe 21 is connected to the inside of the feeding mechanism 8. The first filter membrane 22 is installed at the connection position between the exhaust pipe 21 and the top butt joint pipe 20, and the second filter membrane 23 is installed at the connection position between the exhaust pipe 21 and the feeding mechanism 8. A tray 29 structure that is lifted and lowered by pneumatics is provided inside each independent storage tank 1, and the structure can be used when one of the independent storage tanks 1 is not When filled, by lifting the tray 29, the residual air in the top storage cavity can be squeezed out, thereby reducing the residual air and improving the moisture-proof effect of the internal sodium methoxide. Specifically, when exhaust treatment is performed, the tray 29 can be moved up by the above-mentioned control of the cylinder 4. In this state, it is necessary to control the handwheel 18 at the feeding mechanism 8 to move the sealing column 17 to the middle position between the connection between the top docking pipe 20 of the independent storage tank 1 and the feeding channel 12, and the connection between the exhaust pipe 21 and the feeding channel 12. The air can be discharged from the inside of the exhaust pipe 21, and the sodium methoxide part is blocked by the sealing column 17 to avoid being squeezed out.

[0031] In this embodiment, the feeding mechanism 8 includes a feeding channel 12 and a feeding port 14, the discharging mechanism 9 includes a discharging channel 13 and an independent discharging pipe 19, and sealing columns 17 are installed inside the feeding channel 12 and the discharging channel 13, and one end of the feeding channel 12 and the discharging channel 13 is provided with a threaded sleeve 15, one end of the sealing column 17 is connected to a threaded rod 16, and the threaded rod 16 passes through the inside of the threaded sleeve 15, and a hand wheel 18 is installed at the end of each threaded rod 16, the feeding port 14 is opened at the end of the feeding channel 12, and the feeding mechanism 8 and the discharging mechanism 9 are in an inclined state as a whole. Specifically, by rotating the hand wheel 18 in the feeding mechanism 8 to control the movement of the sealing column 17, the top docking pipe 20 of each independent storage tank 1 can be controlled. The opening state ensures that the sodium methoxide can enter the interior of the independent storage tank 1 from the top. After completing the entire delivery process, the hand wheel 18 can be turned in the opposite direction again to control the sealing column 17 at the end to move toward the position of the feeding port 14 until the top connecting pipe 20 of each independent storage tank 1 is partially blocked, thereby completing the sealing process of the independent storage tank 1. When discharging is required, the hand wheel 18 in the discharging mechanism 9 can be turned to control the sealing column 17 inside the discharging mechanism 9 to move toward the rear end until it passes over the independent discharge pipe 19 at the bottom of the frontmost independent storage tank 1, and the sodium methoxide on the tray 29 can enter the interior of the telescopic tube 30, and then flow from the inside of the telescopic tube 30 into the bottom connecting pipe 27, and finally be discharged outward along the discharging channel 13.
