A liquid infusion tube 13 is transmitted on the mounting plate 12. The upper end of the liquid infusion tube 13 is fixed and connected with a U-shaped tube 5. Two arc grooves 9 are symmetrically arranged on the upper side of the base 1. The two arc grooves 9 are respectively located on both sides of the vacuum insulated cryogenic pressure vessel body 7. Both ends of the U-shaped tube 5 are closed and its two sides pass through the two arc grooves 9 respectively. The two pipe sections of the U-shaped tube 5 located above the base 1 are arranged in a row and are provided with spray heads 6 facing the vacuum insulated cryogenic pressure vessel body 7. An infusion pump 11 is arranged on the bottom side of the base 1. The output end of the infusion pump 11 is rotatably connected and connected with the lower end of the liquid infusion tube 13. A driving mechanism 16 is arranged on the base 1 for driving the U The U-shaped tube 5 is reciprocatingly deflected to evenly spray the vacuum insulated cryogenic pressure vessel body 7. A refrigeration mechanism 2 is provided on the base 1 for reducing the temperature of the solution in the base 1 to improve the cooling effect of the liquid spray on the vacuum insulated cryogenic pressure vessel body 7. The solution in the base 1 is pumped into the U-shaped tube 5 by an infusion pump 11 and sprayed out through a plurality of spray heads 6, thereby spraying on the vacuum insulated cryogenic pressure vessel body 7. During the solution spraying process, the solution in the base 1 is cooled by the refrigeration mechanism 2 to improve the cooling effect of the liquid spray on the vacuum insulated cryogenic pressure vessel body 7. The U-shaped tube 5 is driven to reciprocate by the driving mechanism 16, that is, the pipe section of the U-shaped tube 5 provided with two rows of spray heads 6 reciprocates around the vacuum insulated cryogenic pressure vessel body 7, thereby evenly spraying the vacuum insulated cryogenic pressure vessel body 7. The operation is simple, the use is convenient, and the spraying effect is guaranteed. The base 1 is provided with a liquid filling port 4 for filling the spraying solution therein and a liquid discharge port 8 for discharging the spraying solution.

[0026] Furthermore, the refrigeration mechanism 2 includes a refrigeration box 201 and a circulation pipe 204. The refrigeration box 201 is provided with a water storage chamber 202, and the water storage chamber 202 is filled with cooling water. A gap is left between the refrigeration box 201 and the water storage chamber 202. The gap between the refrigeration box 201 and the water storage chamber 202 is used to fill crushed ice to refrigerate the cooling water in the water storage chamber 202. The refrigeration box 201 is provided with a delivery port 203 for delivering crushed ice and a delivery port 203 for discharging water generated by melting crushed ice; the circulation pipe 204 is arranged in the base 1, and the bottom side of the refrigeration box 201 is provided with a circulation pipe 204.

When spraying liquid, crushed ice is added into the cavity between the refrigeration box 201 and the water storage chamber 202 through the delivery port 203, and the cooling water in the water storage chamber 202 is cooled by the crushed ice. The cooling water in the water storage chamber 202 is pumped through the circulation pipe 204 by the circulation pump 205, and then returned to the water storage chamber 202 to form a cycle. In the process of the cooling water flowing through the base 1, the cooling water exchanges heat with the solution, takes away the heat in the solution to cool it down.

[0027] Furthermore, in this embodiment, the circulation pipe 204 is serpentine to ensure the flow time of the cooling water in the base 1, so that the cooling water has sufficient time to exchange heat with the solution.

The end of the driving rod 1603 away from the turntable 1604 is hinged to the slider 1605. The base 1 is provided with a drive rod 1603 for driving the turntable 1607. The driving motor 1601 that rotates 604 drives the turntable 1604 to rotate through the driving motor 1601. Under the hinged action of the driving rod 1603 and the slider 1605, the rotation of the turntable 1604 drives the slider 1605 to slide back and forth along the slide rail 1606, that is, drives the rack 1602 to move back and forth. Under the meshing action of the rack 1602 and the gear 1607, the reciprocating movement of the rack 1602 drives the U-shaped tube 5 to deflect back and forth, so that the pipe section of the U-shaped tube 5 with two rows of spray heads 6 reciprocates around the vacuum insulated cryogenic pressure vessel body 7, thereby evenly spraying the vacuum insulated cryogenic pressure vessel body 7 with liquid.

[0030] Furthermore, an inner groove 3 is provided on the base 1, and the inner groove 3 is located directly below the vacuum insulation cryogenic pressure vessel body 7. A filter plate 10 is provided at the bottom of the inner groove 3. A rotating rod 14 is fixedly provided on the U-shaped tube 5.

The solution sprayed on the vacuum insulation cryogenic pressure vessel body 7 drips into the inner groove 3, is filtered by the filter plate 10, and returns to the base 1 for recycling. The U-shaped tube 5 cyclically deflects and drives the rotating rod 13 to deflect back and forth in both directions, that is, drives the plurality of strip brushes 15 to brush against the filter plate 10 to prevent dirt from clogging the filter plate 10.

During the solution spraying process, the solution in the base 1 is cooled by the refrigeration mechanism 2 to improve the spray cooling effect on the vacuum insulated cryogenic pressure vessel body 7, and the U-shaped tube 5 is driven to reciprocate by the driving mechanism 16, so that the pipe section of the U-shaped tube 5 provided with two rows of spray heads 6 reciprocates around the vacuum insulated cryogenic pressure vessel body 7, thereby evenly spraying the vacuum insulated cryogenic pressure vessel body 7. The operation is simple, the use is convenient, and the spraying effect is guaranteed.

[0032] The above are only preferred implementations of the utility model. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the concept of the utility model.
