[0029] The reagent product storage tank is usually a container for storing chemical reagents or other liquid substances. These storage tanks are designed to safely store various types of reagents, such as chemical reagents, biological reagents, solvents, etc., to ensure their stability and safety during storage and transportation. The existing storage tanks are mostly sealed by screwing the tank cover with a sealing ring, but the threaded tank cover is prone to misalignment during tightening, resulting in insufficient compression of the sealing ring, reducing the sealing performance of the storage tank, and it is difficult to be found. At the same time, during transportation, the tank cover is prone to loosening due to jolting, which may cause leakage of the reagent.

[0030] In the scheme, the inner cavity of the liquid storage tank 1 is used to store reagents, the reagents can be injected into the inside of the liquid storage tank 1 through the connecting pipe 2, the surface of the liquid storage tank 1 is coated with a coating layer with conductivity, which can help release static electricity and prevent static electricity from accumulating inside the liquid storage tank 1, effectively reducing the risk of static discharge, the user puts the tank cover 6 on the outer end of the connecting pipe 2, the inner wall of the tank cover 6 tightly abuts the outer surface of the connecting pipe 2, and the sealing clamping block 7 at the inner end of the tank cover 6 can be clamped in the first sealing groove 3, the first sealing gasket 8 at the bottom end of the sealing clamping block 7 tightly abuts the inner wall bottom end of the first sealing groove 3, and the material of the first sealing gasket 8 can be rubber, which has good sealing performance. Compared with the traditional threaded cap, the straight insertion design of the tank cover 6 brings convenience to opening and closing, and also reduces the possibility of misalignment. The vacuum pump 5 is a device for removing gas or gas mixture in a closed container to create a vacuum environment. After the user puts the tank cover 6 on the outer end of the connecting pipe 2, the vacuum pump 5 can extract the air in the first sealing groove 3 through the channel 4, so that a vacuum environment is formed between the inner wall of the first sealing groove 3 and the first sealing gasket 8. The negative pressure caused by the vacuum will pull the sealing clamping block 7 downward, so that the tank cover 6 is tightly buckled on the top end of the connecting pipe 2, and the first sealing gasket 8 tightly abuts the inner wall bottom end of the first sealing groove 3. Through the extrusion effect caused by negative pressure, the gap between the first sealing gasket 8 and the inner wall of the first sealing groove 3 can be filled, ensuring the sealing performance of the liquid storage tank 1 and improving the stability of the tank cover 6, so that it will not loosen and effectively prevent the reagents from leaking.

[0031] The position where the connecting pipe 2 meets the liquid storage tank 1 is sleeved with a second sealing gasket 9, the inner end of the second sealing gasket 9 is connected with the liquid storage tank 1 and the connecting pipe 2 respectively, and the cross section of the second sealing gasket 9 is arranged in an L-shaped structure. The bottom end of the tank cover 6 is provided with a second sealing groove 10 matched with the second sealing gasket 9.

[0032] In the scheme, the second sealing gasket 9 can also be made of rubber material. When the user puts the tank cover 6 on the connecting pipe 2, the second sealing groove 10 at the bottom end of the inner wall of the tank cover 6 will be clamped with the second sealing gasket 9, and the negative pressure extrusion effect caused by the vacuum pump 5 will make the inner wall of the second sealing groove 10 tightly abut the second sealing gasket 9, so as to realize two seals on the basis of the clamping of the sealing clamping block 7 and the first sealing groove 3, and further improve the sealing performance of the liquid storage tank 1. The cross section of the second sealing gasket 9 is arranged in an L-shaped structure, which helps to increase the contact area between the second sealing gasket 9 and the inner wall of the second sealing groove 10, and improve the sealing effect of the second sealing gasket 9.

[0033] As Figure 5As shown, the outer end of the tank cover 6 is provided with a plurality of through holes 11 connected with the inner cavity, the plurality of through holes 11 are arranged in a ring shape at equal intervals, the through holes 11 are arranged between the sealing block 7 and the second sealing groove 10, the outer end of the tank cover 6 is provided with an air bag 12, the air bag 12 is arranged in a ring structure, and the air bag 12 covers the plurality of through holes 11, the inner cavity of the air bag 12 is connected with the through holes 11.

[0034] In this scheme, although the first sealing gasket 8 can be tightly abutted with the inner wall of the first sealing groove 3 under the action of the vacuum pump 5, but it still cannot guarantee absolute sealing, because the first sealing gasket 8 may be worn in use, causing the first sealing gasket 8 to be unable to completely adhere to the inner wall of the first sealing groove 3 even under external pressure, and the wear of the first sealing gasket 8 is difficult to be detected by the naked eye, and the reagent may volatilize without the user's knowledge, therefore, in this scheme, the air bag 12 is arranged at the outer end of the tank cover 6, and the outer end of the connecting pipe 2 and the inner wall of the tank cover 6 form a sealed space through the arrangement of the second sealing gasket 9, on this basis, if the first sealing gasket 8 does not adhere tightly with the inner wall of the first sealing groove 3 with the continuous work of the vacuum pump 5, the inner cavity of the first sealing groove 3 will be connected with the space between the connecting pipe 2 and the tank cover 6, and then the vacuum pump 5 can suck the air in the space between the connecting pipe 2 and the tank cover 6, and then suck the air in the air bag 12 through the plurality of through holes 11, the air bag 12 is in a gathered state in the normal state, once the air in the air bag 12 is sucked away, the air bag 12 will be flattened and adhered to the surface of the tank cover 6, the deformation of the air bag 12 is more obvious and easy to be detected by the user, in this way, the user can know the sealing condition in the first sealing groove 3 by observing the air bag 12, once the air bag 12 is flattened, it may be caused by excessive wear of the first sealing gasket 8, so the user can replace the first sealing gasket 8 in time to eliminate the problem.

[0035] As shown in the figure, Figure 6 The bottom end of the liquid storage tank 1 is provided with a plurality of supports 13, the supports 13 can be fixedly connected to the liquid storage tank 1 by bolts, the bottom end of the support 13 is provided with a plurality of universal wheels, the universal wheels can be fixedly connected to the support 13 by bolts, the bottom end of the liquid storage tank 1 is provided with a grounding chain 14, the grounding chain 14 can be fixedly connected to the liquid storage tank 1 by bolts.

[0036] The arrangement of the plurality of universal wheels in this scheme facilitates the movement of the liquid storage tank 1, the grounding chain 14 is always abutted to the ground when the liquid storage tank 1 moves and stops, the function of the grounding chain 14 is to electrically connect the liquid storage tank 1 with the ground, so as to effectively release static electricity or static electricity to the ground, further guaranteeing the anti-static effect of the liquid storage tank 1, thereby preventing static electricity accumulation from causing static electricity discharge accidents.

[0037] Working principle:

[0038] In use, the user fills the inner cavity of the liquid storage tank 1 with the reagent to be stored through the connecting pipe 2, and then fastens the tank cover 6 to the outer end of the connecting pipe 2, so that the inner wall of the tank cover 6 tightly abuts against the outer surface of the connecting pipe 2, the sealing clamping block 7 at the inner end of the tank cover 6 is clamped in the first sealing groove 3, the first sealing gasket 8 at the bottom end of the sealing clamping block 7 tightly abuts against the bottom end of the inner wall of the first sealing groove 3, and the second sealing groove 10 at the bottom end of the tank cover 6 is clamped with the second sealing gasket 9, then the user starts the vacuum pump 5, the vacuum pump 5 draws the air in the first sealing groove 3 through the channel 4, so that a vacuum environment is formed between the inner wall of the first sealing groove 3 and the first sealing gasket 8, the negative pressure caused by the vacuum draws the sealing clamping block 7 downward, so that the tank cover 6 is tightly fastened to the top end of the connecting pipe 2, the first sealing gasket 8 tightly abuts against the bottom end of the inner wall of the first sealing groove 3, and the second sealing gasket 9 tightly abuts against the inner wall of the second sealing groove 10, so that two seals are realized for the inside of the liquid storage tank 1, the extrusion effect caused by the negative pressure fills the gap that may exist between the first sealing gasket 8 and the inner wall of the first sealing groove 3, so as to ensure the sealing of the liquid storage tank 1 and improve the stability of the tank cover 6, so that the tank cover 6 will not be loose, if the first sealing gasket 8 is worn out in long-term use, so that the inner cavity of the first sealing groove 3 cannot be sealed, the vacuum pump 5 will draw the air in the space between the connecting pipe 2 and the tank cover 6 through the first sealing groove 3, and then draw the air in the air bag 12 through the plurality of through holes 11, so that the air bag 12 deforms and adheres to the surface of the tank cover 6, the user can know the sealing condition of the inside of the first sealing groove 3 by observing the air bag 12, once the air bag 12 is flat, it is possible that the first sealing gasket 8 is excessively worn, so the user should replace the first sealing gasket 8 in time to eliminate the problem.

[0039] The above only describes the preferred embodiments of the present application and is not used to limit the present application. Those skilled in the art can make various changes and modifications to the present application.
