AI Technical Summary
When the pressure of existing liquid oxygen storage tanks is too high, the exhaust equipment cannot be completely discharged, resulting in the continuous increase in the pressure in the storage tank, which may cause damage to the tank structure. Replacing the blasting disc requires professional and technical personnel, which is very expensive to repair.
A reinforced explosion-proof liquid oxygen storage tank is designed, adopting a guide tube, sealed joint and blasting plate structure. When the pressure exceeds the threshold, gas is discharged through the guide tube. When the pressure increases further, the blasting plate ruptures quickly reduce pressure when the pressure rises, and the blasting plate replacement process is simplified through the nut and limit ring.
Improve exhaust efficiency, avoid tank damage, simplify the process of replacing the explosion disc, and reduce maintenance costs.

[0019] The technical solution of this patent will be further described in detail below in combination with the specific implementation mode.
[0020] As Figures 1-3 shown, the utility model provides a technical solution: a reinforced explosion-proof liquid oxygen storage tank, including a liquid storage tank 1, one side of the liquid storage tank 1 is fixedly connected with an air flow pipe 2, one end of the air flow pipe 2 is fixedly connected with a guide pipe 3, the top of the guide pipe 3 is provided with a sealing joint 15, the top of the guide pipe 3 is funnel-shaped, the guide pipe 3 is in sealed contact with the sealing joint 15. Because the top of the guide pipe 3 is funnel-shaped, it is convenient for the pressure gas in the liquid oxygen storage tank to act on the sealing joint 15, and the air flow pipe 2 conveys gas, avoiding the liquid in the liquid oxygen storage tank from directly acting on the sealing joint 15.
[0021] Four air flow holes 20 are opened on the side wall of the guide pipe 3, a limiting ring 21 is arranged outside the air flow holes 20, a bursting disc 22 is slidably connected in the limiting ring 21, a nut 19 is threadedly connected to the limiting ring 21, the limiting ring 21 is fixedly connected with the guide pipe 3, the diameter of the bursting disc 22 is larger than the diameter of the air flow holes 20 and is sealed with the air flow holes 20. The bursting disc 22 has a certain pressure threshold. When the pressure exceeds the designed threshold, the bursting disc 22 breaks to exhaust and reduce pressure. The cooperation of the limiting ring 21 and the nut 19 can limit and fix the bursting disc 22, avoiding falling and sealing the air flow holes 20 at the same time.
[0022] The bottom of the surface of the guide pipe 3 is fixedly connected with a first mounting plate 4, the top of the first mounting plate 4 is provided with a second mounting plate 6, the inner surface of the second mounting plate 6 is fixedly connected with a protective cover 5, the bottom of the protective cover 5 is slidably connected with the guide pipe 3, a plurality of threaded holes 7 are opened on the top of the second mounting plate 6, and the threaded holes 7 penetrate through the first mounting plate 4 and the second mounting plate 6. Bolts 8 are threadedly connected in the threaded holes 7. The first mounting plate 4 and the second mounting plate 6 can seal and connect the protective cover 5 and the guide pipe 3. The interaction of the threaded holes 7 and the bolts 8 can fix the first mounting plate 4 and the second mounting plate 6 to avoid the protective cover 5 from falling off.
[0023] Inside the protective cover 5, there is a support plate 13 fixedly connected with a limiting cylinder 14 inside. Inside the limiting cylinder 14, there is a sealing joint 15 and a spring 18. The top of the protective cover 5 is threadedly connected with a lead screw 10. The bottom of the lead screw 10 is provided with a fixing plate 11. The bottom of the fixing plate 11 is fixedly connected with a plurality of support columns 12. The fixing plate 11 is rotatably installed at the bottom of the lead screw 10. The plurality of support columns 12 are evenly arranged on the pressing plate 16 and are located outside the limiting column 17. Due to the provision of the support plate 13, the limiting cylinder 14 can be supported to prevent the limiting cylinder 14 from moving with the sealing joint 15 or the pressing plate 16. Due to the provision of a plurality of support columns 12, the acting force generated by the fixing plate 11 can be evenly applied to the pressing plate 16.
[0024] The bottom of the support column 12 is fixedly connected with a pressing plate 16. A limiting column 17 is slidably connected to the pressing plate 16. The sealing joint 15 and the pressing plate 16 are slidably connected to the limiting cylinder 14. The two ends of the spring 18 are respectively fixedly connected with the top of the sealing joint 15 and the bottom of the pressing plate 16. An exhaust hole 9 is provided on the side wall of the protective cover 5. Due to the provision of the exhaust hole 9, it is convenient to discharge the air in the liquid oxygen storage tank to the outside air. The spring 18 can be compressed through the pressing plate 16 to set the pressure threshold.
[0025] The working principle of the present utility model is as follows: Before use, first rotate the lead screw 10 to drive the fixing plate 11 to move up and down, and then move the pressing plate 16 up and down through the support column 12 to set the exhaust threshold by the compression degree of the spring 18. After setting the threshold, when the pressure in the liquid oxygen storage tank exceeds the set threshold, the gas enters the top of the guiding tube 3 through the air flow tube 2, and then pushes the sealing joint 15 to move up. At this time, the sealing joint 15 is separated from the top of the guiding tube 3, and the gas can be discharged. When the pressure in the liquid oxygen storage tank is less than the set threshold, the acting force generated by the spring 18 pushes the sealing joint 15 to move down until it contacts the top of the guiding tube 3 again, hindering the air flow in the liquid oxygen storage tank from being discharged. When the top of the guiding tube 3 is exhausting and the pressure in the liquid oxygen storage tank is still rising, when the pressure exceeds the threshold of the bursting disc 22, the bursting disc 22 ruptures to quickly exhaust and reduce the pressure. When replacing, remove the threaded hole 7 on the mounting plate two 6 to release the restriction on the protective cover 5. After sliding out the protective cover 5, rotate the nut 19 to remove the ruptured bursting disc 22. After replacement, make the bursting disc 22 in sealed contact with the air flow hole 20 through the nut 19.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific circumstances.
[0027] The above describes the preferred embodiments of the present patent in detail. However, the present patent is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present patent within the scope of knowledge possessed by those of ordinary skill in the art.
