Description

Technical Field

[0001] The invention belongs to the technical field of tank bodies, and in particular relates to a multifunctional low-temperature storage tank and a use method thereof. Background Art

[0002] When the tank is storing liquid nitrogen, the pressure inside the tank will increase, and when the tank is pressurized to discharge liquid nitrogen, the pressure inside the tank will increase. A pressure relief mechanism needs to be provided on the tank to release the excessive pressure inside the tank. In the related art, a rubber ring is provided on the pressure relief mechanism to cover the air outlet to prevent impurities from entering the pressure relief mechanism. However, when the pressure inside the tank is too high and pressure is released, the rubber ring will be blown and displaced by the high-pressure gas.

[0072] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0073] like Figures 1 to 8 As shown, in at least one embodiment, a multifunctional cryogenic storage tank is provided, comprising: a tank body 1, and a pipeline mechanism arranged on the tank body 1; the pipeline mechanism is connected to the inside of the tank body 1, and liquid is poured into the inside of the tank body 1 through the pipeline mechanism; a pressure relief mechanism 2 is arranged on the pipeline mechanism, and the pressure relief mechanism 2 is suitable for pressure relief when the pressure inside the tank body 1 is too high; pressure relief is achieved when the pressure inside the tank body 1 is too high, and the rubber ring 24 is limited during the pressure relief process to ensure that the rubber ring 24 can re-cover the second air outlet 217 in the pressure relief mechanism 2 after the pressure relief is completed; liquid nitrogen or the like may be stored in the tank body 1.

[0074] The pressure relief mechanism 2 includes: a joint assembly and a limit assembly; the joint assembly is connected and communicated with the pipeline mechanism; the limit assembly is sleeved on the joint assembly, and the limit assembly is suitable for limiting the rubber ring 24 in the joint assembly; the limit assembly can limit the rubber ring 24 during pressure relief to prevent the rubber ring 24 from being displaced due to the blowing of high-pressure gas, and to prevent the displaced rubber ring 24 from being unable to re-cover the second air outlet 217; the joint assembly can be communicated with the overflow pipe 33, and the high-pressure gas in the tank body 1 will enter the joint assembly through the overflow pipe 33, and the high-pressure gas will be discharged through the joint assembly; in the related art, the high-pressure gas will blow the rubber ring 24 , causing the rubber ring 24 to deform, the deformed rubber ring 24 will expose the second air outlet 217, and there will be a gap between the deformed rubber ring 24 and the annular groove 216, so that the high-pressure gas can be discharged, but the position of the rubber ring 24 in the related art is uncontrollable, and the high-pressure gas will be blown out from above and below the rubber ring 24. If a worker passes by the tank body 1 at this time, the high-pressure gas blown out from below the rubber ring 24 (the gas in the tank body 1 becomes high-pressure gas when the pressure in the tank body 1 exceeds the preset pressure) will cause damage to the worker. Since liquid nitrogen is stored in the tank body 1, the temperature of the high-pressure gas is very low when it is blown out, and it will cause damage to the worker if it blows on the worker.

[0075] like Figures 2 to 5As shown, the joint assembly includes: a connector 21; the connector 21 is connected to the pipeline mechanism; a first flow channel 211 is provided in the connector 21, and the first flow channel 211 is communicated with the pipeline mechanism; a moving block 22 is provided in the first flow channel 211, and the moving block 22 is slidably connected to the first flow channel 211; a second flow channel 221 is provided in the moving block 22, and the second flow channel 221 is communicated with the first flow channel 211; a first air outlet 222 is provided on the side wall, and the first air outlet 222 is communicated with the second flow channel 221; a chamber 212 is provided in the connector 21, and a piston block 23 is provided in the chamber 212; the outer wall of the piston block 23 is in contact with the inner wall of the chamber 212; the end of the moving block 22 extends into the chamber 212 and contacts the piston block 23; the first flow channel 211 can be communicated with the overflow pipe 33; in the initial state, the first air outlet 222 on the moving block 22 The air outlet 222 will be blocked by the side wall of the first flow channel 211. At this time, the gas in the tank body 1 cannot be discharged from the connector 21, so the tank body 1 is sealed; the side wall of the moving block 22 contacts the inner wall of the first flow channel 211. When the air pressure meets the requirements, the moving block 22 seals the first flow channel 211 to prevent the gas with too low temperature in the tank body 1 from being discharged; when the air pressure in the tank body 1 is too high, the high-pressure gas will push the moving block 22 to move downward, and the moving block 22 will push the piston block 23 to move downward The first air outlet 222 on the moving block 22 will extend into the chamber 212, and the high-pressure gas will enter the chamber 212 through the first air outlet 222. At this time, the high-pressure gas will continue to push the piston block 23 to move downward until the top surface of the piston block 23 is lower than the second air outlet 217. At this time, the high-pressure gas will blow the rubber ring 24 through the second air outlet 217 to deform and move the rubber ring 24. The rubber ring 24 will expose the covered second air outlet 217, so that the high-pressure gas can be discharged.

[0076] like Figure 7 As shown, an adjusting block 213 is threadedly connected to the connector 21, and a portion of the adjusting block 213 extends into the chamber 212; a first spring 214 is connected between the adjusting block 213 and the piston block 23; a hexagonal hole 215 is provided on the adjusting block 213; in the initial state, the piston block 23 can be close to the inner top surface of the chamber 212 through the first spring 214, and the first spring 214 will be squeezed when the piston block 23 moves downward, and the piston block 23 is reset by the first spring 214 after the high-pressure gas is discharged; the degree of squeezing of the first spring 214 can be adjusted through the adjusting block 213, that is, the supporting force applied by the first spring 214 to the piston block 23 is adjusted to adjust the pressure relief standard of the tank body 1, and the upward movement of the adjusting block 213 will squeeze the first spring 214, and at this time, the supporting force applied by the first spring 214 to the piston block 23 becomes larger.

[0077] An annular groove 216 is provided on the outer wall of the connector 21; a plurality of second air outlet holes 217 connected to the chamber 212 are provided in the annular groove 216; a rubber ring 24 is provided in the annular groove 216, and the rubber ring 24 is suitable for covering the second air outlet holes 217; there may be a plurality of connection points between the rubber ring 24 and the inner wall of the annular groove 216, and the second air outlet holes 217 may be exposed when the rubber ring 24 is deformed and moved by the high-pressure gas.

[0078] like Figure 6 As shown, the limit assembly includes: a movable sleeve 25; the movable sleeve 25 is sleeved on the connecting head 21; the movable sleeve 25 is slidably arranged between the connecting head 21, and the movable sleeve 25 is rotatably arranged between the connecting head 21; the bottom surface of the movable sleeve 25 is sealed, and the bottom surface of the movable sleeve 25 is located below the bottom surface of the connecting head 21; a plurality of connecting rods 251 are arranged on the side wall of the movable sleeve 25, and the length direction of the connecting rods 251 is arranged along the axial direction of the movable sleeve 25; the connecting rods 251 are arranged along the axial direction of the movable sleeve 25; 51 extends to the outer wall of the connecting head 21; one end of the connecting rod 251 is connected to the movable sleeve 25, and the other end of the connecting rod 251 is connected to one end of the inclined rod 252, and the inclined rod 252 is inclined in a direction away from the outer wall of the connecting head 21; the other end of the inclined rod 252 is connected to one end of the cross bar 253, and the length direction of the cross bar 253 is arranged along the radial direction of the movable sleeve 25; the other end of the connecting rod 251 contacts the outer wall of the connecting head 21; the inclined rod 252 and the cross bar 253 form a groove that is away from the connecting head 21. In the initial state, the cross bar 253 and the tilting rod 252 are arranged higher than the annular groove 216, and the piston block 23 is in contact with the column 255. When the high-pressure gas needs to be released, the piston block 23 moves downward to drive the column 255 to move downward, and the column 255 moves downward to drive the movable sleeve 25 to move downward, so that the angle formed by the tilting rod 252 and the cross bar 253 moves to the annular groove 216. At this time, the piston block 23 also moves to the bottom of the second air outlet 217, and the high-pressure gas blows up the rubber ring 24. The bulging rubber ring 24 The rubber ring 24 is limited by the tilting rod 252 and the cross bar 253 and cannot move up and down, but can only deform along the shape surrounded by the tilting rod 252 and the cross bar 253. In addition, due to the limitation of the tilting rod 252, the gap between the rubber ring 24 and the annular groove 216 only exists at the top surface of the rubber ring 24, and the high-pressure gas can only be blown out from above the rubber ring 24 to avoid damage to the staff. In addition, the rubber ring 24 cannot move up and down. After the high-pressure gas is discharged, the rubber ring 24 can restore its deformation and still cover the second air outlet 217 to prevent impurities from entering the chamber 212.

[0079] like Figure 8As shown, a hollow block 254 is provided on the inner bottom surface of the movable sleeve 25; a column 255 is provided in the block 254, the column 255 extends from the block 254, and the column 255 passes through the hexagonal hole 215 and extends into the chamber 212; one end of the column 255 contacts the piston block 23; a limiting ring 256 is provided on the column 255, the limiting ring 256 is provided close to the bottom end of the column 255, and the limiting ring 256 is located in the block 254; the bottom end of the column 255 is in contact with the inner bottom surface of the block 254. A second spring 259 is arranged between the cylinder 255 and the hexagonal hole 215; a plurality of protrusions 257 are arranged on the inner bottom surface of the block 254; a notch 258 corresponding to the protrusion 257 is opened on the side wall of the limiting ring 256; after the high-pressure gas is discharged, the first spring 214 will drive the piston block 23 to reset. Since the piston block 23 contacts the inner wall of the chamber 212, during the reset process, the piston block 23 will be tilted and stuck in the chamber 212 and cannot be reset due to the uneven friction between the side wall of the piston block 23 and the inner wall of the chamber 212. When the movable sleeve 25 moves downward, a low-pressure space is formed between the inner bottom surface of the movable sleeve 25 and the bottom surface of the connector 21. When the high-pressure gas is released, the pressure of the high-pressure gas on the piston block 23 is transmitted to the column 255, which prevents the movable sleeve 25 from resetting. After the high-pressure gas is released, the external air pressure is greater than the pressure between the inner bottom surface of the movable sleeve 25 and the bottom surface of the connector 21. The external air pressure drives the movable sleeve 25 to reset. During the resetting process, the column 255 assists the piston block 23 in resetting, reducing the tilting of the piston block 23 caused by uneven friction. If the piston block 23 is tilted and stuck in the chamber 212, the movable sleeve 25 will be The sleeve 25 cannot be reset. At this time, the staff only needs to observe with the naked eye whether the movable sleeve 25 is reset to know whether the piston block 23 is reset. The staff can manually push the movable sleeve 25 upward to assist the piston block 23 to reset; when the adjusting block 213 needs to be adjusted, the staff only needs to push the bottom surface of the movable sleeve 25 upward so that the protrusion 257 moves to the corresponding notch 258, and then the staff rotates the movable sleeve 25 to drive the column 255 to rotate to adjust the adjusting block 213; the second spring 259 can reset the column 255 and the block 254.

[0080] In the initial state, the first air outlet 222 on the moving block 22 will be blocked by the side wall of the first flow channel 211. At this time, the gas in the tank body 1 cannot be discharged from the connecting head 21, thereby realizing the sealing of the tank body 1; the side wall of the moving block 22 contacts the inner wall of the first flow channel 211, and when the air pressure meets the requirements, the moving block 22 seals the first flow channel 211 to prevent the gas with too low temperature in the tank body 1 from being discharged; when the air pressure in the tank body 1 is too high, the high-pressure gas will push the moving block 22 to move downward, and the moving block 22 will push the piston block 23 to move downward, and the first air outlet 222 on the moving block 22 will extend into the chamber 212, and the high-pressure gas will enter the chamber 212 through the first air outlet 222, and at this time the high-pressure gas will continue to push the piston block 23 to move downward, Until the top surface of the piston block 23 is lower than the second air outlet 217, at this time, the high-pressure gas will blow the rubber ring 24 through the second air outlet 217, and the downward movement of the piston block 23 will drive the column 255 to move downward, and the downward movement of the column 255 will drive the movable sleeve 25 to move downward, so that the angle formed by the tilting rod 252 and the cross bar 253 moves to the annular groove 216. At this time, the piston block 23 also moves just below the second air outlet 217, and the high-pressure gas blows up the rubber ring 24. The bulged rubber ring 24 is limited by the tilting rod 252 and the cross bar 253. The rubber ring 24 cannot move up and down, and can only deform along the shape surrounded by the tilting rod 252 and the cross bar 253. In addition, due to the limitation of the tilting rod 252, the rubber ring 24 and the annular groove 216 are The gap only exists at the top surface of the rubber ring 24, and the high-pressure gas can only be blown out from the top of the rubber ring 24 to avoid damage to the staff, and the rubber ring 24 cannot move up and down. After the high-pressure gas is discharged, the rubber ring 24 recovers its deformation and can still cover the second air outlet 217 to prevent impurities from entering the chamber 212; after the high-pressure gas is discharged, the first spring 214 will drive the piston block 23 to reset. Since the piston block 23 is in contact with the inner wall of the chamber 212, during the reset process, due to the uneven friction between the side wall of the piston block 23 and the inner wall of the chamber 212, the piston block 23 will be tilted and stuck in the chamber 212 and cannot be reset. When the piston block 23 moves downward, the inner bottom surface of the moving sleeve 25 and the bottom surface of the connector 21 are moved. A low-pressure space is formed. When the high-pressure gas is released, the pressure of the high-pressure gas on the piston block 23 is transmitted to the cylinder 255, which prevents the movable sleeve 25 from resetting. After the high-pressure gas is released, the external air pressure is greater than the pressure between the inner bottom surface of the movable sleeve 25 and the bottom surface of the connector 21. The external air pressure drives the movable sleeve 25 to reset. During the resetting process, the cylinder 255 will assist the piston block 23 in resetting, reducing the tilting of the piston block 23 caused by uneven friction. If the piston block 23 is tilted and stuck in the chamber 212, the movable sleeve 25 will be unable to reset. At this time, the staff only needs to observe with the naked eye whether the movable sleeve 25 is reset to know whether the piston block 23 is reset. The staff can manually push the movable sleeve 25 upward to assist the piston block 23 in resetting.When the adjustment block 213 needs to be adjusted, the staff only needs to push the bottom surface of the movable sleeve 25 upwards so that the protrusion 257 moves to the corresponding notch 258, and then the staff rotates the movable sleeve 25 to drive the column 255 to rotate to adjust the adjustment block 213. ;
