[0024] A storage device for tert-butyl acetate includes: a base plate 1, on which a low-temperature storage tank 2 and a cooling medium conveying assembly are disposed; a base 3 is disposed below the low-temperature storage tank 2; a discharge pipe 4 is disposed at the bottom of the low-temperature storage tank 2; a first control valve 5 is disposed on the discharge pipe 4; an installation groove 6 is disposed on the outer wall of the low-temperature storage tank 2; an external insulation layer 7 and a cooling medium flow pipe 9 are disposed within the installation groove 6; a top cover 12 is disposed on the top of the low-temperature storage tank 2; a feed pipe 13 is disposed on the top cover 12; a second control valve 14 is disposed on the feed pipe 13; and the cooling medium conveying assembly... The medium delivery assembly includes a cooling medium storage tank 17 and a cooling medium transfer tank 18. A cooling medium delivery pump 19 is installed on the cooling medium storage tank 17. The cooling medium delivery pump 19 is equipped with a first delivery pipe 20 and a second delivery pipe 24. The other end of the first delivery pipe 20 is connected to the cooling medium flow pipe 9, and the other end of the second delivery pipe 24 is connected to the interior of the cooling medium storage tank 17. A return pipe 21 is installed on the cooling medium transfer tank 18. The other end of the return pipe 21 is connected to the cooling medium flow pipe 9. A controller 25 is installed on the cryogenic storage tank 2.

[0025] Open the second control valve 14 to introduce tert-butyl acetate into the low-temperature storage tank 2 through the feed pipe 13. Turn on the cooling medium transfer pump 19 to draw the cooling medium from the cooling medium storage tank 17 through the first transfer pipe 20 and the second transfer pipe 24, and deliver it to the cooling medium flow pipe 9 to ensure that the temperature of the low-temperature storage tank 2 is maintained at the temperature most suitable for storing tert-butyl acetate. When the cooling medium in the cooling medium flow pipe 9 reaches the bottom, it flows back to the cooling medium transfer tank 18 for cooling before entering the cooling medium storage tank 17 for recycling.

[0026] The base 3 is provided with a bottom insulation layer 8, and the discharge pipe 4 passes through the base 3 and the bottom insulation layer 8.

[0027] The bottom insulation layer 8 increases the insulation effect at the bottom of the low-temperature storage tank 2.

[0028] The cooling medium flow pipe 9 includes an annular pipe body 91, which surrounds the outside of the low-temperature storage tank 2 and is located between the mounting groove 6 and the external insulation layer 7. The upper end of the annular pipe body 91 is provided with an inlet 92, which is connected to the first conveying pipe 20. The lower end of the annular pipe body 91 is provided with a return port 93, which is connected to the return pipe 21.

[0029] The cooling medium enters the annular pipe body 91 from the first delivery pipe 20 and the inlet 92, flows downward and absorbs heat, and finally enters the cooling medium transfer box 18 from the return port 93 and the end of the return pipe 21.

[0030] The top of the cryogenic storage tank 2 is provided with a first sealing groove 10, and the bottom of the top cover 12 is provided with a second sealing groove 16. A sealing ring 11 is provided between the first sealing groove 10 and the second sealing groove 16.

[0031] The sealing ring 11 reduces the possibility of tert-butyl acetate evaporating from the top cover 12.

[0032] An infrared thermometer 15 is provided in the middle part of the top cover 12.

[0033] Infrared thermometer 15 performs real-time temperature detection of tert-butyl acetate inside the low-temperature storage tank 2.

[0034] The bottom of the cooling medium transfer box 18 is provided with a transfer pipe 22, the other end of which is connected to the bottom of the cooling medium storage box 17, and a third control valve 23 is provided on the transfer pipe 22.

[0035] When the cooling medium leaves the cooling medium flow pipe 9 from the return pipe 21 and enters the cooling medium transfer box 18, it is cooled down in the cooling medium transfer box 18. When the temperature of the cooling medium in the cooling medium transfer box 18 drops to a certain limit, the controller opens the third control valve 23 (the third control valve 23 is a one-way valve), so that the cooling medium enters the cooling medium storage box 17 and is transported to the cooling medium flow pipe 9 again by the cooling medium delivery pump 19.

[0036] The working principle of the tert-butyl acetate storage device provided by this utility model is as follows:

[0037] Open the second control valve 14 to introduce tert-butyl acetate into the low-temperature storage tank 2 through the feed pipe 13. Turn on the cooling medium transfer pump 19 to draw the cooling medium from the cooling medium storage tank 17 through the first transfer pipe 20 and the second transfer pipe 24, and deliver it to the cooling medium flow pipe 9 to ensure that the temperature of the low-temperature storage tank 2 is maintained at the temperature most suitable for storing tert-butyl acetate. When the cooling medium in the cooling medium flow pipe 9 reaches the bottom, it flows back to the cooling medium transfer tank 18 for cooling before entering the cooling medium storage tank 17 for recycling.

[0038] Compared with related technologies, the storage device for tert-butyl acetate provided by this utility model has the following advantages:

[0039] By circulating the cooling medium, the temperature of the low-temperature storage tank 2 can be precisely maintained within the range most suitable for storing tert-butyl acetate, effectively suppressing adverse chemical reactions such as decomposition, oxidation, and volatilization that may be caused by temperature fluctuations in tert-butyl acetate, and ensuring the stability of the product's chemical properties during storage. The cooling medium circulates between the cooling medium storage tank 17, the cooling medium flow pipe 9, and the cooling medium transfer tank 18, which greatly reduces the consumption of the cooling medium and lowers the cost of using the cooling medium.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
