Description

Technical Field

[0001] This utility model relates to the technical field of liquefied gas transport tanks, specifically a safety liquefied gas transport tank with a built-in pressure relief valve. Background Technology

[0002] Liquefied gas transport tanks are specialized equipment used to transport various liquefied gases. They play an indispensable role in many industries such as energy and chemicals. As specialized transport equipment tailored for various liquefied gases, liquefied gas transport tanks play a crucial and irreplaceable role in many fields such as energy extraction and chemical industry.

[0003] If the pressure relief valve is designed to be external, it is at risk of being damaged by external impacts, which may cause it to fail to perform its pressure relief function properly. In extreme situations, such as when a vehicle rolls over or is involved in a violent collision, the external pressure relief valve is very likely to fail due to mechanical damage. This failure is extremely dangerous because it may lead to a series of serious consequences, including but not limited to a sharp rise in pressure inside the tank, leakage of liquefied gas, or even an explosion, thereby posing a significant threat to personnel safety, the environment, and surrounding facilities.

[0029] This utility model provides the following technical solution:

[0030] Example 1

[0031] Combination Figures 1 to 5 A safety liquefied gas transport tank with a built-in pressure relief valve includes a liquefied gas transport tank 1 and an outer shell 8. There are two outer shells 8. A pressure relief valve 4 is fixedly connected to the top of the liquefied gas transport tank 1. A pipe 6 is fixedly connected to one side of the pressure relief valve 4. A long plate 5 is fixedly connected between the pressure relief valve 4 and the liquefied gas transport tank 1. A shell cover 7 is hinged to one side of the outer shell 8. A disassembly mechanism 2 is provided on the outer shell 8. A connection mechanism 3 is provided on the shell cover 7 and the outer shell 8.

[0032] The disassembly mechanism 2 includes an assembly component 21 and a fixing component 22, with the fixing component 22 located at the bottom of the assembly component 21;

[0033] The fixing component 22 includes a connecting plate 214, which is fixedly connected to the upper left and right sides of the outer casing 8. The connecting plate 214 has slots 215 on both sides inside, and the front and rear sides of the slots 215 are open. A plate 216 is inserted into the slots 215. The connecting plate 214 has slots 213 on the top and bottom. The plate 216 has a long slot 219 on the side away from the outer casing 8, and the side of the long slot 219 away from the outer casing 8 is open. A long block 217 is inserted into the long slot 219. The upper and lower long blocks 217 are fixedly connected to the outside of the two long blocks 217. The top and bottom of the fixing plate 218 are respectively hinged to hinge plates 212. A block 211 is fixedly connected to the side of the hinge plate 212 near the connecting plate 214.

[0034] The openings of the upper and lower slots 213 are corresponding to each other. The surface of the block 211 and the inside of the slot 213 are engaged. The connecting plate 214 has a through groove on the side away from the outer shell 8. The surface of the long block 217 is inserted through the through groove on the side of the connecting plate 214 away from the outer shell 8.

[0035] The fixing component 22 includes a T-slot 225, which is opened on the top of the long plate 5. The lower ends of the left and right sides of the outer shell 8 are respectively fixedly connected to the connecting seat 223. The bottom of the connecting seat 223 is fixedly connected to the T-block 222. Nuts 224 are fixedly connected to the outer sides of the front and rear connecting seats 223. The screw 221 is threaded inside the nut 224.

[0036] There are two T-slots 225, which are located on the left and right sides of the pressure relief valve 4. There are four T-blocks 222, which are arranged in pairs. The surface of the T-blocks 222 and the interior of the T-slots 225 are slidably connected. The connecting seat 223 has a through hole slot inside, and the surface of the screw 221 is inserted through the through hole slot inside the connecting seat 223.

[0037] Furthermore, the hinge plate 212 drives the locking block 211 to be taken out of the locking slot 213, pulls the fixing plate 218 to drive the long block 217 to be taken out of the long slot 219, and pulls the insert plate 216 to be taken out of the slot 215. At the same time, after the screw 221 is unscrewed, the outer shell 8 can be pulled directly, so that the outer shell 8 finally drives the T-shaped block 222 to slide in the T-shaped slot 225, and the outer shell 8 can be disassembled. Meanwhile, the outer shell 8 is made of high-strength, impact-resistant engineering plastic and is filled with heat insulation material, which can not only prevent the pressure relief valve 4 from being accidentally hit, but also play a certain role in heat insulation.

[0038] Example 2

[0039] See Figure 1-7Furthermore, based on Embodiment 1, the connecting mechanism 3 includes a mounting base 34, which is fixedly connected to the top left and right sides of the shell cover 7. The upper ends of the left and right sides of the outer shell 8 are respectively fixedly connected to a fixing base 31. The fixing base 31 is set on the top of the connecting plate 214. A fixing rod 36 is fixedly connected to the top of the fixing base 31. A rotating plate 32 is rotatably connected to the surface of the fixing rod 36. Rectangular grooves 35 are opened on the outer sides of the front and rear mounting bases 34. Bolts 33 are threadedly connected to the top of the rotating plate 32 and the mounting base 34. The left and right sides and the outer sides of the rectangular grooves 35 on the front and rear sides are set as openings. The surface of the rotating plate 32 and the inside of the rectangular grooves 35 are inserted.

[0040] Furthermore, after the bolt 33 is unscrewed, the rotating plate 32 is rotated on the surface of the fixed rod 36, causing the rotating plate 32 to move out of the rectangular groove 35. The cover 7 can then be directly opened by hinge at the top of the outer casing 8, facilitating regular inspection, maintenance, and calibration of the pressure relief valve 4.

[0041] In actual operation, when this device is used, since the pressure relief valve 4 is installed at the center of the top of the liquefied gas transport tank 1, the pressure change inside the tank can be detected most quickly and accurately. A circular mounting hole with a matching size to the pressure relief valve connection port is opened on the top of the liquefied gas transport tank 1. A flange connection is used to ensure a tight and stable connection. A reinforcing flange is set around the mounting hole to increase the local strength of the top of the tank and prevent deformation caused by long-term pressure impact. A multi-stage buffer chamber is set in the pipeline 6. A labyrinth-type baffle is set inside the chamber. When high-pressure gas is discharged from the pressure relief valve, it first enters the buffer chamber. Through multiple deflections by the baffle, the gas velocity and pressure are reduced, avoiding high-speed airflow from harming the surrounding environment. The outlet of the buffer chamber is connected to a dedicated discharge pipeline outside the tank. A silencer and gas purification device are set at the end of the discharge pipeline to reduce emission noise and environmental pollution.

[0042] When the hinge plate 212 is rotated on one side of the fixed plate 218, the hinge plate 212 drives the locking block 211 to be taken out of the locking slot 213, and the fixed plate 218 is pulled to drive the long block 217 to be taken out of the long slot 219. Then the insert plate 216 is pulled out of the slot 215. At the same time, after the screw 221 is unscrewed, the outer shell 8 can be pulled directly, so that the outer shell 8 finally drives the T-shaped block 222 to slide in the T-shaped slot 225, and the outer shell 8 can be disassembled. The outer shell 8 is made of high-strength, impact-resistant engineering plastic and filled with heat insulation material, which can not only prevent the pressure relief valve 4 from being hit by accident, but also play a certain role in heat insulation.

[0043] After removing the bolt 33 by threading it, rotate the rotating plate 32 on the surface of the fixed rod 36 so that the rotating plate 32 moves out of the rectangular groove 35. The cover 7 can then be directly rotated to open the hinge on the top of the outer casing 8, which facilitates the regular inspection, maintenance and calibration of the pressure relief valve 4.
