However, this utility model only focuses on the sealing of the storage tank, and cannot ensure that the volatilized gas is discharged in time, so that the gas will accumulate in the tank body and cause pressure to the storage tank, which cannot be adapted to high volatility materials.

[0004] Therefore, the utility model proposes a high volatility material storage device to solve the above problems. Utility Model Content

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A high-volatility material storage device comprises a tank body and a tank cover, wherein the tank cover is detachably connected to the upper end of the tank body through a connecting assembly, the upper end of the tank cover is connected to a nitrogen flow control box through a gas transmission pipe, and the nitrogen flow control box is connected to a nitrogen storage tank; a refrigeration box is connected to the surrounding side of the tank body, a lower end of one side of the refrigeration box is connected to a refrigerant inlet, and an upper end of the other side of the refrigeration box is connected to a refrigerant outlet; an exhaust pipe is connected to the side wall of the tank body, the exhaust pipe runs through the refrigeration box, and a one-way valve is connected to the end of the exhaust pipe; a discharge pipe is arranged at the lower end of the tank body, and a butterfly valve is connected to the discharge pipe.

The one-way valve can discharge the gas in the tank body in time to avoid the danger caused by excessive pressure in the tank body. At the same time, when nitrogen is injected, the original gas in the tank body can also be discharged through the one-way valve, which increases the contact area between nitrogen and high-volatile materials and reduces the oxygen content in the tank body.

[0009] Furthermore, a pressure gauge is connected to the tank cover, and a second sealing strip is provided between the pressure gauge and the tank cover.

[0010] By adopting the above technical solution, the pressure of the tank body can be detected and the flow rate of nitrogen can be adjusted.

[0011] Furthermore, an observation window is provided on the tank cover.

[0012] By adopting the above technical solution, the material status can be checked regularly through the observation window, and problems can be discovered and solved in time, which avoids the staff from frequently opening the can lid for inspection, reduces the contact between the staff and the material, and reduces safety risks.

[0013] Furthermore, a first sealing strip is provided between the tank body and the tank cover.

[0014] By adopting the above technical solution, the sealing performance of the tank body can be ensured.

[0015] Furthermore, a heat-insulating layer is connected to the outer side of the tank body.

[0016] By adopting the above technical solution, the temperature of the tank body can be stabilized.

[0017] Furthermore, a grid is provided at the interface of the tank body corresponding to the exhaust pipe.

[0018] By adopting the above technical solution, when the high volatility material is in solid state, the material can be blocked by the grid to avoid clogging of the exhaust pipe by the material.

[0019] Furthermore, the lower end of the butterfly valve is connected to a feeding assembly, which includes a spiral blade and a driving motor. The driving motor drives the spiral blade to rotate in the feeding pipe. A partition is arranged between the driving motor and the spiral blade, and a feeding trough is opened on the side wall of the upper end of the partition.

[0020] By adopting the above technical solution, it is possible to avoid large-area contact of the material with the outside air, and then the material falls through the discharge pipe, and the driving motor drives the spiral blade to rotate in the discharge pipe, ensuring smooth material discharge.

[0021] In summary, compared with the prior art, the utility model has the following beneficial effects:

[0022] The end of the exhaust pipe of the utility model is connected with a one-way valve. In practical applications, the height of the one-way valve on the tank body needs to be selected according to whether the high-volatility material is solid or liquid. The one-way valve can discharge the gas in the tank body in time to avoid the danger caused by excessive pressure in the tank body. At the same time, when nitrogen is injected, the original gas in the tank body can also be discharged through the one-way valve, which increases the contact area between nitrogen and high-volatility materials and reduces the oxygen content in the tank body. At the same time, the refrigeration box can control the temperature of the tank body, ensure the stability of the material, reduce the possibility of material reaction, and slow down the volatilization speed of the material.
