Description

Technical Field

[0001] This utility model relates to the field of storage tank technology, specifically a double vacuum insulation device with a protective mechanism. Background Technology

[0002] The dual vacuum insulation device with protective mechanisms is a professional storage tank designed specifically for ultra-low temperature liquefied gases such as liquid oxygen, liquid nitrogen, and liquid hydrogen, with storage temperatures as low as -269℃. Through the synergistic operation of the dual vacuum insulation structure and the composite protection system, it achieves long-term stable storage of the medium and all-round safety protection.

[0003] Currently, in existing technologies, during the transportation of cryogenic liquefied gas storage tanks, the liquid medium inside the tank experiences violent shaking due to dynamic conditions such as vehicle bumps, sudden braking, and turning. This shaking not only causes high-frequency impacts between the liquid and the tank wall, leading to fatigue damage to the tank structure, but also exacerbates the vaporization rate of the medium, causing a sudden increase in pressure. At the same time, the vortices formed by the fluctuations on the liquid surface and the disturbances at the gas-liquid interface can easily cause instability in the gas-liquid two-phase flow, which may trigger malfunctions of safety valves or leaks at pipeline connections in severe cases. In view of this, we propose a dual vacuum insulation device with a protection mechanism. Utility Model Content

[0004] The main objective of this invention is to provide a double vacuum insulation device with a protective mechanism, which can solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes a double vacuum insulation device with a protective mechanism, including a support base, an outer shell fixedly connected above the support base, an inner liner inside the outer shell, and a protective mechanism inside the inner liner. The protective mechanism includes a partition plate, which is rotatably connected to the inner wall of the inner liner.

[0006] Preferably, the partition plate is provided with through holes, and the partition plate is provided with multiple sets of through holes, which are distributed in an alternating manner.

[0007] Preferably, the partition is provided with a movable groove, and a rotating rod is fixedly connected to the movable groove. The rotating rod and the movable groove are connected by a torsion spring.

[0008] Preferably, the partition is rotatably connected to the inner wall of the inner liner via a rotating rod.

[0009] Preferably, a fixing plate is fixedly connected to the inner wall of the inner liner, a sliding rod is fixedly connected to the fixing plate, a slider is slidably connected to the sliding rod, and springs are fixedly connected to both side walls of the slider, with the end of the spring away from the side wall of the slider being fixedly connected to the fixing plate.

[0010] Preferably, the slider is rotatably connected to a connecting rod, and the end of the connecting rod away from the slider is rotatably connected to a connecting block. The connecting block is fixedly connected to the side wall of the partition. As the liquid flows towards the partition, it flows to the next partition through the through holes on the partition. When the liquid flows towards the partition, it causes the partition to rotate to a certain extent. With the cooperation of the connecting rod and the connecting block, the partition that it is connected to will also rotate to a certain extent. With the cooperation of the sliding rod and the spring, the partition will be reset, thereby reducing the amplitude of liquid sloshing. At the same time, with the cooperation of the movable groove, the rotating rod and the torsion spring, the partition will be further reset, thereby further reducing the amplitude of liquid sloshing. Through the design of the staggered through holes on multiple sets of partitions, a certain resistance can be generated when the liquid flows, thereby reducing the amplitude of liquid sloshing to a certain extent.

[0011] Preferably, the outer shell is provided with a connecting pipe one, and the inner liner is connected to a connecting pipe two. Perlite is injected into the interlayer between the outer shell and the inner liner through the connecting pipe one, thereby ensuring the heat insulation performance of the storage tank.

[0012] This invention provides a double vacuum insulation device with a protective mechanism. It has the following beneficial effects:

[0013] (1) The double vacuum insulation device with protection mechanism allows liquid to flow to the partition and then to the next partition through the through hole on the partition. When the liquid flows to the partition, it will cause the partition to rotate to a certain extent. With the cooperation of the connecting rod and the connecting block, the partition that it cooperates with will also rotate to a certain extent. With the cooperation of the sliding rod and the spring, the partition will be reset, thereby reducing the amplitude of liquid sloshing. At the same time, with the cooperation of the movable groove, the rotating rod and the torsion spring, the partition will be reset, thereby further reducing the amplitude of liquid sloshing.

[0014] (2) The double vacuum insulation device with protection mechanism can generate a certain resistance when the liquid flows through the design of multiple sets of through holes on the partition plates, thereby reducing the liquid sloshing amplitude to a certain extent.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6 This utility model proposes a double vacuum heat preservation device with a protective mechanism, including a support base 1, an outer shell 2 fixedly connected above the support base 1, an inner liner 4 inside the outer shell 2, and a protective mechanism 6 inside the inner liner 4. The protective mechanism 6 includes a partition 61, which is rotatably connected to the inner wall of the inner liner 4.

[0027] In this embodiment of the utility model, in order to enable the protection mechanism 6 to operate better, specifically, the partition 61 is provided with through holes, and the partition 61 is provided with multiple sets of through holes, which are staggered. The partition 61 is provided with a movable groove 62, and a rotating rod 63 is fixedly connected to the movable groove 62. The rotating rod 63 and the movable groove 62 are connected by a torsion spring 64. The partition 61 is rotatably connected to the inner wall of the inner liner 4 through the rotating rod 63. A fixing plate 65 is fixedly connected to the inner wall of the inner liner 4, and a sliding rod 66 is fixedly connected to the fixing plate 65. A slider 67 is slidably connected to the sliding rod 66. Springs 68 are fixedly connected to both side walls of the slider 67. The end of the spring 68 away from the side wall of the slider 67 is fixedly connected to the fixing plate 65.

[0028] Furthermore, slider 67 is rotatably connected to connecting rod 69, and the end of connecting rod 69 away from slider 67 is rotatably connected to connecting block 610. Connecting block 610 is fixedly connected to the side wall of partition 61. Liquid flows towards partition 61 and through the through hole on partition 61 to the next partition 61. When liquid flows towards partition 61, it causes partition 61 to rotate to a certain extent. With the cooperation of connecting rod 69 and connecting block 610, the partition 61 that it is connected to will also rotate to a certain extent. With the cooperation of slider 66 and spring 68, the partition 61 will rotate. The positioning reduces the amplitude of liquid sloshing. At the same time, the cooperation of the movable groove 62, the rotating rod 63 and the torsion spring 64 will further drive the baffle 61 to reset, thereby further reducing the amplitude of liquid sloshing. Through the design of the staggered through holes on the multiple sets of baffles 61, a certain resistance can be generated when the liquid flows, thereby reducing the amplitude of liquid sloshing to a certain extent. The outer shell 2 is provided with a connecting pipe 3, and the inner liner 4 is connected to a connecting pipe 5. Perlite is injected into the interlayer between the outer shell 2 and the inner liner 4 through the connecting pipe 3, thereby ensuring the heat insulation performance of the storage tank.

[0029] In this invention, during use, perlite is injected into the interlayer between the outer shell 2 and the inner liner 4 through the connecting pipe 3 to ensure the heat insulation performance of the storage tank. During transportation, the liquid cryogenic liquefied gas inside the storage tank will slosh around. At this time, the liquid will rush towards the baffle 61 and flow to the next baffle 61 through the through holes on the baffle 61. When the liquid rushes towards the baffle 61, it will cause the baffle 61 to rotate to a certain extent. With the cooperation of the connecting rod 69 and the connecting block 610, the baffle 61 that it cooperates with will also rotate to a certain extent. With the cooperation of the sliding rod 66 and the spring 68, the baffle 61 will be reset, thereby reducing the amplitude of liquid sloshing. At the same time, with the cooperation of the movable groove 62, the rotating rod 63 and the torsion spring 64, the baffle 61 will be reset, thereby further reducing the amplitude of liquid sloshing. In addition, the design of the staggered through holes on the multiple sets of baffles 61 can generate a certain resistance when the liquid flows, thereby reducing the amplitude of liquid sloshing to a certain extent.
