Its main function is to extract and concentrate the krypton-depleted xenon in the liquid oxygen so that it can be purified in subsequent processes or directly sold. The liquid oxygen after concentration of krypton-depleted xenon can be used as medical liquid oxygen. When moving the storage tanks used to store raw materials, the storage tanks are prone to collision with other objects, causing damage to the tank body. If the storage temperature is too high during storage, it is easy to cause flash evaporation of the raw material liquid, thereby affecting the storage stability. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The liquid oxygen and krypton-depleted xenon raw material storage tank is provided with a liquid storage tank, a liquid pump, a cooling pipe, a liquid inlet pipe, a liquid outlet pipe and a thermal insulation layer. Cold water or liquid nitrogen is injected into the liquid storage tank from the liquid injection port through an external pipe. The liquid pump is then started to extract the cold water or liquid nitrogen, which is transported to the cooling pipe through the liquid inlet pipe. The spiral cooling pipe enables the cold water or liquid nitrogen to flow evenly through the inner tank body and finally flow back into the liquid storage tank through the liquid outlet pipe. The cold water or liquid nitrogen lowers the temperature of the inner tank body, preventing the krypton-depleted xenon raw material liquid from being overheated and flashing. The thermal insulation layer maintains the temperature, reduces temperature loss, and improves the stability of the krypton-depleted xenon raw material liquid during storage and discharge.

[0013] 2. The storage tank for liquid oxygen, krypton-depleted xenon raw materials is equipped with an outer tank body, a protective plate, a buffer spring, a universal wheel, an electric push rod and a support plate. The staff can pull the pull rod to make the universal wheel roll, thereby facilitating the staff to move the storage tank to the working position. Then, by starting the electric push rod, the support plate is pushed to move so that the support plate contacts the ground, thereby cooperating with the universal wheel to fix the fixing seat. When a bump occurs, the protective plate will compress the buffer spring to cushion the bump and impact and avoid damage to the outer tank body. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: a storage tank for liquid oxygen krypton-depleted xenon raw materials, comprising an outer tank body 1, a fixing seat 2 fixedly connected to the outer tank body 1, an inner tank body 3 connected to the inside of the outer tank body 1, a thermal insulation layer 4 provided on the inner wall of the outer tank body 1, a buffer spring 5 connected to the outer wall of the outer tank body 1, one end of the buffer spring 5 connected to a protective plate 6, the protective plate 6 is arc-shaped, and a total of ten protective plates 6 are evenly distributed in a centrally symmetrical manner, a buffer pad 20 is connected to the protective plate 6, and the buffer spring 5 is compressed by multiple protective plates 6 to buffer the impact caused by collision, thereby preventing the outer tank body 1 from being damaged by collision, and the buffer pad 20 can protect the protective plate 6.

[0021] A plurality of connecting pipes 7 are connected to the bottom of the inner tank body 3, a vent valve port 8 is installed above the inner tank body 3, a cooling pipe 9 is installed between the inner tank body 3 and the outer tank body 1, one end of the cooling pipe 9 is connected to a liquid inlet pipe 10, and the other end of the cooling pipe 9 is connected to a liquid outlet pipe 11. The cooling pipe 9 is spiral and wound around the outer wall of the inner tank body 3, and the liquid outlet pipe 11 is connected to the liquid storage tank 13. The spiral cooling pipe 9 can increase the contact area with the inner tank body 3 and extend the cooling path, thereby improving the cooling efficiency.

[0022] A plurality of universal wheels 12 are installed under the fixed base 2, and a liquid storage tank 13 is installed on the fixed base 2. A liquid pump 17 is installed on the liquid storage tank 13 through a pipeline. The liquid storage tank 13 is connected to a liquid injection port 18, and a liquid discharge port 19 is connected to one side of the liquid storage tank 13. The liquid inlet pipe 10 is connected to the liquid pump 17. By connecting an external water pipe to the liquid injection port 18 and the liquid discharge port 19, cold water or liquid nitrogen is injected into the liquid storage tank 13 from the liquid injection port 18 through the pipeline, and the liquid discharge port 19 can facilitate the discharge of the liquid, thereby facilitating the replacement of the liquid and avoiding the increase of the liquid temperature due to long-term use and affecting the subsequent cooling efficiency.

[0023] A plurality of electric push rods 14 are installed on the fixed seat 2, and the movable ends of the electric push rods 14 are connected to support plates 15. There are four universal wheels 12 evenly distributed in a rectangular array. The support plate 15 is located between two universal wheels 12. A rubber pad 21 is connected under the support plate 15. When the support plate 15 contacts the ground, the rubber pad 21 will be squeezed, thereby fitting with the ground to increase friction, and cooperating with the multiple universal wheels 12 to fix the fixed seat 2.

[0024] A pull rod 16 is connected to one side of the fixing seat 2. The fixing seat 2 is designed to be U-shaped as a whole. The connecting pipe 7 passes through the outer tank body 1. A control valve 22 is installed on the connecting pipe 7. The staff can pull the fixing seat 2 to move by the pull rod 16, thereby moving the storage tank, which is convenient and quick.

[0025] The working principle of this utility model is:

[0026] When the fixing seat 2 is pulled to the working position by the pull rod 16, the electric push rod 14 is started, so that the electric push rod 14 pushes the support plate 15 to move, causing the support plate 15 to contact the ground, thereby cooperating with the universal wheel 12 to fix the position of the fixing seat 2. When a collision occurs, the protective plate 6 will compress the buffer spring 5, thereby buffering the bumps and impacts. Cold water or liquid nitrogen is injected into the liquid storage tank 13 from the liquid injection port 18 through an external pipe. The liquid pump 17 can extract the cold water or liquid nitrogen in the liquid storage tank 13 and transport it to the cooling pipe 9 through the liquid inlet pipe 10. The spiral cooling pipe 9 can make the cold water or liquid nitrogen flow evenly through the inner tank body 3, thereby reducing the temperature of the inner tank body 3 through the cold water or liquid nitrogen, avoiding the flash evaporation of the krypton-depleted xenon raw material liquid due to excessive temperature, and the cold water or liquid nitrogen after absorbing heat will flow back into the liquid storage tank 13 through the liquid outlet pipe 11.
