Description

Technical Field

[0001] The present invention relates to the technical field of vacuum insulation, specifically a vacuum multi-layer insulation system for a refrigerant liquid storage container. Background Art

[0002] In the refrigeration industry, the storage of refrigerants is crucial. The traditional insulation methods for refrigerant liquid storage containers have poor effects and cannot effectively prevent the intrusion of external heat. Ordinary thermal insulation materials have a high thermal conductivity. Over time, a large amount of heat is transferred into the liquid storage container, resulting in an increase in the temperature and pressure fluctuations of the refrigerant. This not only reduces the refrigeration efficiency but also increases energy consumption. In scenarios such as long-distance transportation or long-term storage, the problem is more prominent, and it may even cause changes in the performance of the refrigerant, affecting the normal operation of refrigeration equipment. At the same time, in the existing structural design of liquid storage containers, insufficient consideration is given to the fixation and protection of the liquid storage container, and it is easily affected by vibration and collision during handling and transportation, resulting in damage to the liquid storage container and posing a safety hazard of refrigerant leakage.

[0003] For example, a fixed multi-layer vacuum insulation high-pressure liquid hydrogen storage tank with the publication number CN107228274A realizes the vacuum isolation between the stored liquid and the external environment through the inner cylinder and the outer cylinder provided.

Detailed implementation manners

[0019] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0020] Please refer to Figures 1 to 14 , the present invention provides the following technical solutions: Embodiment 1: A vacuum multi-layer insulation system for a refrigerant liquid storage device, including a cylinder 1, a heat insulation pad 2 is fixedly connected to the bottom of the cylinder 1, a fixed rod 3 is fixedly connected to the bottom of the cylinder 1, a buffer pad 4 is fixedly connected to the upper end of the fixed rod 3, a storage tank 5 is clamped to the upper end of the buffer pad 4 through a fastening component 10, two connecting pipes 6 are fixedly connected to the upper end of the storage tank 5, and a valve 7 is fixedly connected to the surface of the connecting pipe 6.

[0021] During use, first place the storage tank 5 inside the cylinder 1, support the storage tank 5 through the fixing rod 3 and the buffer pad 4, and charge and discharge the liquid stored inside the storage tank 5 through the connecting pipe 6 and the valve 7.

[0022] Embodiment 2: The technical solution of this embodiment different from that of Embodiment 1 includes: an adiabatic component 8 is provided on the surface of the storage tank 5. The adiabatic component 8 includes a vacuum sleeve 81, the vacuum sleeve 81 is movably sleeved on the outer wall of the storage tank 5, a fixing ring 82 is fixedly connected to the inner wall of the upper end of the vacuum sleeve 81, a sealing ring 83 is clamped inside the vacuum sleeve 81, a cover ring 84 is fixedly connected to the upper end of the sealing ring 83, and a plurality of arc plates 89 are fixedly connected to the lower surface of the sealing ring 83. A plurality of positioning grooves 810 are formed on the surface of the arc plate 89, and a steel ring 811 is clamped inside the positioning groove 810.

[0023] A plurality of through holes 85 are formed on the upper surface of the cover ring 84, a plurality of round holes 86 are formed on the surface of the sealing ring 83, a plurality of threaded grooves 87 are formed on the surface of the fixing ring 82, bolts 88 are inserted into the through holes 85 and the round holes 86, and the lower ends of the bolts 88 are threadedly connected inside the threaded grooves 87.

[0024] The inner wall of the arc plate 89 fits with the inner wall of the vacuum sleeve 81. The steel ring 811 is arranged around the center of the vacuum sleeve 81. The inner side inner wall of the vacuum sleeve 81 is supported by the arc plate 89, and the arc plate 89 is reinforced by the steel ring 811.

[0025] The inner and outer side walls of the sealing ring 83 respectively fit with the two inner walls of the vacuum sleeve 81. The opening at the upper end of the vacuum sleeve 81 is blocked by the sealing ring 83 to prevent the pressure in the vacuum sleeve 81 from changing.

[0026] During use, first sleeve the vacuum sleeve 81 on the outer wall of the storage tank 5, then clamp the sealing ring 83 at the upper end opening of the vacuum sleeve 81, then press the cover ring 84 to drive the sealing ring 83 to fit with the fixing ring 82, then insert the bolt 88 into the through hole 85 and the round hole 86, and then rotate the bolt 88 to be threadedly connected inside the threaded groove 87. The cover ring 84 is connected to the vacuum sleeve 81 through the bolt 88 to keep the vacuum sleeve 81 in a stable vacuum state. The sealing ring 83 drives the arc plate 89 to be clamped on the inner wall of the vacuum sleeve 81. The arc plate 89 is stably fixed by the steel ring 811 embedded on the surface of the arc plate 89. When the storage tank 5 is filled with refrigerant, it can be ensured that the inner wall of the vacuum storage tank 81 will not be deformed to affect the sealing effect. At the same time, the storage tank 5 is reinforced by the arc plate 89 to prevent the storage tank 5 from expanding due to excessive internal pressure.

[0027] Embodiment 3: The technical solution of this embodiment different from that of Embodiment 2 includes: The fastening assembly 10 includes a diamond-shaped block 101. A fixing groove 54 matching with the buffer pad 4 is provided at the bottom of the storage tank 5. The buffer pad 4 is detachably arranged in the fixing groove 54. A first horizontal hole 53 communicating with each other is provided on one side of the fixing groove 54. A vertical hole 52 communicating with each other is provided at the top of the first horizontal hole 53. A second horizontal hole 51 communicating with each other is provided at the top of the vertical hole 52; A diamond-shaped block 101 is movably arranged in the second horizontal hole 51. A clamp 102 is fixedly sleeved on the diamond-shaped block 101. The vacuum sleeve 81 and the diamond-shaped block 101 are respectively in movable contact; A guiding rod 103 is movably arranged in the vertical hole 52. A first notch matching with the hypotenuse of the diamond-shaped block 101 is provided at the top of the guiding rod 103. The diamond-shaped block 101 and the top of the guiding rod 103 are in movable contact; A wedge-shaped block 104 is movably arranged in the first horizontal hole 53. A second notch matching with the hypotenuse of the wedge-shaped block 104 is provided at the bottom of the guiding rod 103. The wedge-shaped block 104 and the bottom of the guiding rod 103 are in movable contact; A bayonet 41 is provided on the buffer pad 4. The wedge-shaped block 104 is detachably arranged in the bayonet 41. A fixing plate 105 is fixed near the edge of the first horizontal hole 53. An elastic member 106 is provided between the fixing plate 105 and the wedge-shaped block 104. The two ends of the elastic member 106 can be respectively fixedly connected with the fixing plate 105 and the wedge-shaped block 104. The design of the fastening assembly 10 during use makes the installation of the storage tank 5 more secure, and can avoid the storage tank 5 being in a stable installation state when the pressing cover ring 84 is not installed. During the installation process, the buffer pad 4 is snapped into the fixing groove 54. When the vacuum sleeve 81 is sleeved on the outer wall of the storage tank 5, the vacuum sleeve 81 contacts the oblique edge of the diamond block 101 extending out of the second transverse hole 51, and the diamond block 101 moves inward. The oblique edge of the diamond block 101 moving inward contacts the first cutout at the top of the guide rod 103, so that the guide rod 103 moves downward. The second cutout of the guide rod 103 moving downward contacts the oblique edge of the wedge block 104, so that the wedge block 104 moves into the bayonet 41 on the buffer pad 4, thereby fixing the storage tank 5 and the buffer pad 4. The elastic member 106 is stretched, and the elastic member 106 can be a spring, so that the two ends of the spring are respectively connected to the fixing plate 10 5 and the wedge block 104 are fixedly connected, and when performing maintenance and disassembly, it is only necessary to pull out the vacuum sleeve 81 upwards. After the vacuum sleeve 81 is pulled out, the elastic member 106 is not reset by external force, so that the wedge block 104 is retracted from the bayonet 41 on the buffer pad 4, and the oblique edge of the wedge block 104 contacts the second cutout of the guide rod 103, so that the guide rod 103 moves upward, and the first cutout at the top of the guide rod 103 contacts the oblique edge of the diamond block 101, and the diamond block 101 moves outward and extends out of the second transverse hole 51, which is convenient for subsequent use; in the above, the edge of the second transverse hole 51 is closed, and the clamp 102 on the diamond block 101 prevents the diamond block 101 from moving too much and disengaging from the second transverse hole 51. Secondly, when the buffer pad 4 is not clamped in the fixing groove 54, the guide rod 103 will not fall due to the obstruction of the wedge block 104.

[0028] Embodiment 4: The technical solution of this embodiment that is different from that of Embodiment 3 includes: a fixing component 9 is arranged on the inner wall of the cylinder 1, the fixing component 9 includes a top cover 91, the top cover 91 is clamped on the upper end of the cylinder 1, a multi-layer insulation layer 11 is arranged on the inner wall of the cylinder 1, the multi-layer insulation layer 11 is composed of a radiation screen and a spacer, the radiation screen is made of double-sided aluminum-plated polyester film, and the spacer is made of glass fiber paper, a fixing cylinder 92 is fixedly connected to the inner wall of the multi-layer insulation layer 11, a plurality of vertical openings 93 are opened on the inner wall of the fixing cylinder 92, a card slot 94 is opened on the inner wall of the vertical opening 93, a plug plate 95 is inserted inside the vertical opening 93, one end of the plug plate 95 is fixedly connected to the outer wall of the vacuum sleeve 81, and the other end of the plug plate 95 is fixedly connected to a clamping plate 96, and the clamping plate 96 is clamped inside the clamping slot 94.

[0029] When in use, the design of the fixing component 9 makes the installation and maintenance of the device more convenient. During the installation process, just insert the plug board 95 into the vertical opening 93 and make the clamping board 96 snap into the clamping groove 94, then the fixation of the vacuum sleeve 81 and the storage tank 5 can be completed. In this way, the outer wall of the vacuum storage tank 81 can be fixed to prevent large deformation of the outer wall of the vacuum storage tank 81 from affecting the sealing effect. When performing maintenance, the plug board 95 can also be relatively easily pulled out from the vertical opening 93 to realize the disassembly of the vacuum sleeve 81 and the storage tank 5, facilitating operations such as inspection, repair, and replacement of components inside the device.
