[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1-4As shown, a recovery device for a cryogenic liquid oxygen storage tank comprises a cryogenic liquid oxygen storage tank body 1, a liquid oxygen evaporation recovery assembly 2 is arranged on the outer surface of one end of the cryogenic liquid oxygen storage tank body 1, a waterproof and dustproof recovery and heat dissipation assembly 3 is arranged on the outer surface of the upper end of the liquid oxygen evaporation recovery assembly 2, a support leg 4 is arranged on the outer surface of the other end of the cryogenic liquid oxygen storage tank body 1, a liquid oxygen storage tank bottom pipeline 5 is arranged in the middle of the other end of the cryogenic liquid oxygen storage tank body 1, the liquid oxygen evaporation recovery assembly 2 comprises a recovery device shell 201, a support base 202, a one-way valve 203, a booster pump 204, an L-shaped elbow 205, a cryogenic cooler 206 and a heat insulation cover 207, and the waterproof and dustproof recovery and heat dissipation assembly 3 comprises an arc cover plate 301, a circular slot 302, a sealing mounting ring 303, a circular dust cover 304, a waterproof cover plate 305, a heat dissipation fan 306 and a confluence cover 307.

[0026] It should be noted that the utility model is a recovery device for a cryogenic liquid oxygen storage tank. When in use, the cryogenic liquid oxygen storage tank body 1 is first supported by the support legs 4, and cryogenic liquid oxygen is injected into the cryogenic liquid oxygen storage tank body 1 to perform cryogenic storage work on it. When the cryogenic liquid oxygen storage tank body 1 is stored at low temperature, the liquid oxygen vaporization recovery component 2 is used to recover the liquid oxygen vaporization, and when the liquid oxygen vaporization recovery component 2 is working, the waterproof and dustproof recovery heat dissipation component 3 is used to protect it and perform heat dissipation work. The liquid oxygen vaporization recovery component 2 includes a recovery device. The housing 201, the support base 202, the one-way valve 203, the booster pump 204, the L-shaped elbow 205, the cryocooler 206 and the heat shield 207 are used. When in use, the booster pump 204 first extracts the oxygen inside the cryogenic liquid oxygen storage tank through the one-way valve 203, and then transfers it to the cryocooler 206 through the L-shaped elbow 205. The cryocooler 206 compresses the gas and removes the heat in the oxygen through the principle of heat absorption by compression, thereby completing the cryogenic liquefaction of the oxygen. When performing cryogenic cooling, the heat shield 207 is used to prevent the heat from damaging the workpiece. The working environment is affected, and the liquefied liquid oxygen flows back to the cryogenic liquid oxygen storage tank through the booster exhaust pipe at the bottom of the cryogenic cooler 206. When in use, the evaporated oxygen inside the cryogenic liquid oxygen storage tank can be cryogenically liquefied, which can not only avoid pressure fluctuations inside the tank but also avoid waste of stored oxygen. The waterproof and dustproof recovery heat dissipation component 3 includes an arc cover plate 301, a circular groove 302, a sealing mounting ring 303, a circular dust cover 304, a waterproof cover plate 305, a heat dissipation fan 306 and a confluence cover 307. When in use, the heat dissipation fan 306 is first started to transfer the low The high-temperature gas inside the heat insulation cover 207 of the warm cooler 206 is guided to be discharged through the circular dust cover 304. When the circular dust cover 304 is in use, its stability and sealing are ensured by the circular groove 302 and the sealing mounting ring 303. At the same time, the waterproof cover plate 305 on the top of the circular dust cover 304 prevents rainwater from corroding the inside of the arc cover plate 301. When in use, the heat generated by the recovery device can be quickly discharged, thereby ensuring the stability and recovery efficiency of the recovery equipment, and preventing it from being corroded by water and dust while dissipating heat.
