[0029] Referring to Figure 1 and Figure 2 , the vacuum storage tank is used to accommodate low-temperature liquid, so as to realize the storage and transportation of low-temperature liquid and improve the use efficiency of low-temperature liquid.

[0030] The vacuum storage tank comprises an outer tank body and an inner tank body. The outer tank body is sleeved outside the inner tank body, so that a vacuum interlayer is formed between the outer tank body and the inner tank body, so as to improve the heat insulation performance of the vacuum storage tank. The inner tank body is used to accommodate low-temperature liquid.

[0034] Figure 3 is a partial enlarged view of A in Figure 2 . Figure 4 is a sectional view of the ambient temperature adsorption device of the present application. Figure 5 is Figure 4A sectional view at B-B.

[0035] Referring to Figures 2 to 5 The application provides a normal-temperature adsorption device 300, which is arranged in a vacuum interlayer 110 of a vacuum storage tank. The normal-temperature adsorption device 300 comprises a fixed shaft 310, a rotating body 330 and a blocking piece 340. The fixed shaft 310 is used for fixedly connecting to the vacuum storage tank. The rotating body 330 is rotatably sleeved on the fixed shaft 310. The rotating body 330 is internally provided with a storage bin 331 for accommodating an adsorbent, and the storage bin 331 extends around the circumference of the fixed shaft 310. A plurality of drop openings 332 are formed in the circumferential wall of the rotating body 330, and the drop openings 332 are communicated with the storage bin 331. A plurality of air holes 333 are formed in the rotating body 330, and the air holes 333 are communicated with the storage bin 331 and the vacuum interlayer 110. The blocking piece 340 is detachably arranged on the drop opening 332 of the rotating body 330, so as to block the drop opening 332.

[0036] When the normal-temperature adsorption device 300 is used, the fixed shaft 310 is fixedly connected to the vacuum storage tank, and the fixed shaft 310 is located in the vacuum interlayer 110. Then, the rotating body 330 is rotatably sleeved on the fixed shaft 310.

[0037] When the staff fills the adsorbent, the rotating body 330 is rotated, so that the staff can quickly and accurately select the drop opening 332 and put the adsorbent into the storage bin 331 through the drop opening 332. Then, the drop opening 332 is blocked by the blocking piece 340, so as to fill the adsorbent in the storage bin 331, thereby realizing the quick and accurate dropping and use of the adsorbent, effectively improving the assembly efficiency and use efficiency of the normal-temperature adsorption device 300. Moreover, the contact time of the adsorbent with the external environment can be effectively reduced, and the adsorption effect and service life of the adsorbent are guaranteed.

[0038] Referring to Figures 3 to 5 In the embodiment, the fixed shaft 310 is fixedly connected to the outer tank body 100. The fixed shaft 310 can support the rotating body 330, improve the reliability and stability of the normal-temperature adsorption device 300, and avoid the normal-temperature adsorption device 300 from falling off. The fixed shaft 310 can also transmit the heat in the rotating body 330 to the outer tank body 100.

[0039] The outer periphery of the fixed shaft 310 is provided with a limiting portion 311. A clamping member 320 is detachably arranged on the fixed shaft 310, and the clamping member 320 is detachably connected with the fixed shaft 310. The limiting portion 311 and the clamping member 320 can respectively abut against the two side walls of the rotating body 330 along the axial direction of the fixed shaft 310, so as to limit the rotating body 330 between the limiting portion 311 and the clamping member 320, thereby facilitating the installation and disassembly of the rotating body 330, and facilitating the rotating of the rotating body 330 around the fixed shaft 310 to fill the adsorbent, and improving the assembly efficiency and use efficiency of the normal-temperature adsorption device 300.

[0040] In some embodiments, the limiting portion 311 is arranged in a ring shape along the outer periphery of the fixed shaft 310, so as to effectively increase the contact area of the limiting portion 311 and the rotating body 330, facilitate the rotation of the rotating body 330, and improve the connection strength and reliability of the limiting portion 311 and the rotating body 330.

[0041] The limiting portion 311 extends along the axial direction of the fixed shaft 310, so that one end surface of the limiting portion 311 is flush with the end surface of the fixed shaft 310, thereby forming a concentric cylindrical structure of the fixed shaft 310 and the limiting portion 311, so as to increase the contact area between the fixed shaft 310 and the outer tank body 100, thereby improving the connection strength and reliability between the fixed shaft 310 and the outer tank body 100.

[0042] Referring to Figures 3 to 5 In the present embodiment, the free end of the fixed shaft 310 is recessed with a clamping groove 312, and the clamping groove 312 is arranged in a ring shape along the circumferential direction of the fixed shaft 310. The clamping member 320 is an elastic clamping member 320, which can be sleeved on the fixed shaft 310 and can be limited in the clamping groove 312, so that the clamping member 320 can be accommodated and limited in the clamping groove 312, thereby limiting one end of the rotating body 330 away from the limiting portion 311, facilitating the installation and disassembly of the normal-temperature adsorption device 300.

[0043] It can be understood that when the fixed shaft 310 is connected with the outer tank body 100, the free end of the fixed shaft 310 is the end of the fixed shaft 310 away from the outer tank body 100.

[0044] In some embodiments, the clamping member 320 is an elastic retaining ring, which can be elastically stretched to be sleeved on the fixed shaft 310 and can move along the axial direction of the fixed shaft 310. The elastic retaining ring can also move along the fixed shaft 310 into the clamping groove 312 and elastically contract to be embedded in the clamping groove 312, so that the elastic retaining ring can abut against the rotating body 330 with the limiting portion 311, respectively, to limit the movement and displacement of the rotating body 330 along the axial direction of the fixed shaft 310. The clamping groove 312 and the elastic retaining ring can realize the rapid assembly of the normal-temperature adsorption device 300, thereby improving the assembly efficiency and reliability of the normal-temperature adsorption device 300.

[0045] In some embodiments, the free end of the fixed shaft 310 can be provided with a clamping hole, the axial direction of the clamping hole being perpendicular to the axial direction of the fixed shaft 310. The clamping member 320 can be a clamping pin or a clamping bolt, which is detachably clamped in the clamping hole of the fixed shaft 310, thereby limiting the movement of the rotating body 330 along the fixed shaft 310.

[0046] Referring to Figures 3 to 5 In the present embodiment, the fixed shaft 310 and the outer tank body 100 can be welded, thereby improving the connection strength of the fixed shaft 310 and the outer tank body 100, overcoming the mutual influence of the outer tank body 100 and the fixed shaft 310 when they are heated or cooled, and improving the reliability and stability between the normal-temperature adsorption device 300 and the outer tank body 100.

[0047] In some embodiments, the material of the fixed shaft 310 can be stainless steel or low-alloy steel, so that the heat on the fixed shaft 310 can be quickly transferred to the outer tank body 100. The material of the fixed shaft 310 can also be non-alloy steel.

[0048] Referring to Figures 3 to 5 In the present embodiment, the rotating body 330 can be in a cylindrical shape, and the axis of the rotating body 330 is coaxial with the axis of the fixed shaft 310, so as to facilitate the rotation of the rotating body 330 by the staff.

[0049] The middle part of the rotating body 330 is provided with a rotating hole, and the axis of the rotating hole is coaxial with the axis of the fixed shaft 310. The rotating hole is used to accommodate the fixed shaft 310, so that the rotating body 330 can be sleeved on the fixed shaft 310. When the rotating body 330 is sleeved on the fixed shaft 310, the rotating body 330 is located between the limiting portion 311 and the clamping member 320, so as to avoid the movement of the rotating body 330 along the fixed shaft 310 during the transportation of the vacuum storage tank.

[0050] In some embodiments, the rotating body 330 can be in a prismatic structure.

[0051] Referring to Figures 3 to 5 In the present embodiment, the rotating body 330 is provided with a storage bin 331 for accommodating the adsorbent, so as to facilitate the storage and replacement of the adsorbent and improve the use efficiency of the normal-temperature adsorption device 300.

[0052] In some embodiments, a plurality of storage bins 331 can be provided in the rotating body 330. The plurality of storage bins 331 are arranged in a ring shape, so that the plurality of storage bins 331 can be arranged in sequence around the fixed shaft 310. Each storage bin 331 is respectively provided with at least one feeding port 332, so as to facilitate the feeding and replacement of the adsorbent and improve the assembly efficiency and use efficiency of the normal-temperature adsorption device 300.

[0053] A plurality of storage bins 331 are formed in the rotating body 330, and the adsorbent can be split and respectively placed in the plurality of storage bins 331. The adsorbent can be used to adsorb the gas such as hydrogen and nitrogen in the vacuum interlayer 110. The adsorbent generates heat when adsorbing the gas in the vacuum interlayer 110, and the adsorbent is stored separately. On the one hand, the adsorbent stack can be reduced, and the actual adsorption area can be increased. On the other hand, the heat transfer and concentration can be avoided, so as to avoid the rapid temperature rise to trigger a chain reaction, reduce the chemical reaction speed, and improve the heat insulation effect of the vacuum interlayer 110.

[0054] In addition, after the adsorbent stored separately reacts, the heat generated can be transferred to the outer tank body 100 through the rotating body 330 and the fixed shaft 310, and discharged to the outside, so as to further reduce the influence of the heat generated by the adsorbent when adsorbing the gas on the vacuum interlayer 110, and ensure the cold preservation effect of the vacuum storage tank.

[0055] In other embodiments, the plurality of storage bins 331 can also be used to respectively fill different types of adsorbent, so as to increase the operability of the normal temperature adsorption device 300 and improve the application range of the normal temperature adsorption device 300.

[0056] In other embodiments, the outer peripheral wall of the rotating body 330 is provided with a placing opening 332 relative to each storage bin 331, so as to realize the placing and replacement of the adsorbent.

[0057] Referring to Figures 3 to 5 In this embodiment, the rotating body 330 is provided with a plurality of air holes 333 on the opposite two side walls along the fixed shaft 310, so as to facilitate the reaction of the adsorbent with the gas in the vacuum interlayer 110 and improve the adsorption effect of the adsorbent.

[0058] In some embodiments, the diameter of the air hole 333 is less than 1.5 mm, so as to effectively avoid the adsorbent from falling into the vacuum interlayer 110 through the air hole 333, and facilitate the storage and replacement of the adsorbent.

[0059] In some embodiments, the material of the rotating body 330 can be steel material.

[0060] In some embodiments, the rotating body 330 can include an outer cylinder 3341, an inner cylinder 3342, two end plates 3343, and a plurality of partition plates 3344. The outer cylinder 3341 is sleeved outside the inner cylinder 3342, and the outer cylinder 3341 and the inner cylinder 3342 are coaxially arranged. The two end plates 3343 are annular, and are respectively located at the two ends of the axis of the outer cylinder 3341 to respectively seal the outer cylinder 3341 and the inner cylinder 3342. The outer cylinder 3341, the inner cylinder 3342, and the two end plates 3343 enclose a cavity. The plurality of partition plates 3344 are spaced apart and accommodated in the cavity, and extend along the radial direction of the outer cylinder 3341 to divide the cavity into a plurality of storage compartments 331. The outer cylinder 3341 is provided with a drop port 332 relative to the plurality of storage compartments 331. The two end plates 3343 are each provided with a plurality of air holes 333.

[0061] Referring to Figures 3 to 5 In the present embodiment, the blocking member 340 is detachably connected in the drop port 332 of the rotating body 330, so as to facilitate the input and replacement of the adsorbent.

[0062] In some embodiments, the blocking member 340 is threadedly connected with the rotating body 330, so as to improve the connection strength and reliability between the blocking member 340 and the rotating body 330. In other embodiments, the blocking member 340 can be a bolt.

[0063] Figure 6 is Figure 5 Structure diagram of the structure shown in FIG. 6 after the anti-loosening member is installed.

[0064] Referring to Figures 3 to 6 In the present embodiment, the blocking member 340 is detachably connected in the drop port 332 of the rotating body 330, so as to facilitate the input and replacement of the adsorbent.

[0065] In some embodiments, the anti-loosening hole 341 extends along a direction perpendicular to the extension direction of the blocking member 340. The anti-loosening member 350 is connected with at least two blocking members 340, so as to limit the blocking member 340 on the rotating body 330, thereby improving the assembly and disassembly efficiency between the anti-loosening member 350 and the blocking member 340.

[0066] In other embodiments, the anti-loosening member 350 can be an anti-loosening steel wire. The anti-loosening steel wire can extend along the circumference of the rotating body 330 to pass through the anti-loosening holes 341 of all the blocking members 340, so that all the blocking members 340 can be locked by one anti-loosening steel wire, avoiding the blocking members 340 from rotating due to thermal expansion and contraction, vibration, etc., and avoiding the blocking members 340 from loosening and coming out of the rotating body 330.

[0067] When the staff needs to disassemble the blocking members 340 to replace the adsorbent, the staff only needs to disassemble one anti-loosening steel wire to unlock all the blocking members 340, thereby effectively improving the assembly and disassembly efficiency of the normal-temperature adsorption device 300, facilitating subsequent replacement of the adsorbent, and reducing the replacement time of the adsorbent.

[0068] In other embodiments, the diameter of the anti-loosening steel wire can be φ1mm-φ1.5mm stainless steel wire.

[0069] In other embodiments, the anti-loosening member 350 can also be a bolt, a clamp, etc., as long as it can avoid the blocking members 340 from coming out of the rotating body 330 during use of the normal-temperature adsorption device 300.

[0070] Referring to Figures 1 to 6 The application provides a normal-temperature adsorption device 300 which can be fixedly connected to an outer tank body 100. When the normal-temperature adsorption device 300 is assembled, the fixed shaft 310 is first fixedly connected to the inner wall of the outer tank body 100, and then the rotating body 330 is sleeved on the rotating shaft. After the rotating body 330 is sleeved on the rotating shaft, the clamping member 320 is clamped in the clamping groove 312, so that the limiting portion 311 and the clamping member 320 abut against the two side walls of the rotating body 330 along the axial direction of the fixed shaft 310.

[0071] Then, one or more adsorbents are filled into the plurality of storage bins 331, and the blocking members 340 are blocked in the drop openings 332 to limit the adsorbents in the storage bins 331. Finally, the anti-loosening member 350 passes through the anti-loosening holes 341 of the plurality of blocking members 340 to limit the rotation of the blocking members 340. The normal-temperature adsorption device 300 has high assembly efficiency, effectively reduces the contact time of the adsorbent with the external environment, and guarantees the adsorption effect and service life of the adsorbent.

[0072] On the one hand, the adsorbent can adsorb the gas in the vacuum interlayer 110 to improve the cold insulation effect of the vacuum interlayer 110; on the other hand, the heat generated by the adsorbent when absorbing the gas can be transmitted to the outer tank body 100 through the rotating body 330 and the fixed shaft 310, reducing the influence of the heat generated by the adsorbent on the inner tank body 200, and improving the cold insulation effect of the vacuum storage tank.

[0073] Referring to Figures 1 to 6The application also provides a vacuum storage tank, which comprises an outer tank body 100, an inner tank body 200 and the normal-temperature adsorption device 300 according to any one of the above. The inner tank body 200 is accommodated in the outer tank body 100, and a vacuum interlayer 110 is formed between the inner tank body 200 and the outer tank body 100. The normal-temperature adsorption device 300 is located in the vacuum interlayer 110 and is fixedly connected to the outer tank body 100.

[0074] When the vacuum storage tank is in use, the high-temperature adsorption device can effectively adsorb the gas in the vacuum interlayer 110, and can also transfer the heat generated by the adsorbent during the adsorption process to the outer tank body 100 through the rotating body 330 and the fixed shaft 310, thereby improving the cold preservation effect of the vacuum storage tank.

[0075] In the embodiment, a hand hole (not shown in the figure) is formed in the outer tank body 100 on the side of the normal-temperature adsorption device 300. The vacuum storage tank further comprises a closing valve which is detachably arranged on the hand hole to block the hand hole.

[0076] When the normal-temperature adsorption device 300 needs to be filled or the adsorbent needs to be replaced, the staff can open the closing valve, remove the locking piece 350 and the blocking piece 340 by closing method, fill the adsorbent into the storage bin 331, or replace the adsorbent in the storage bin 331. Then, the blocking piece 340 and the locking piece 350 are assembled on the rotating body 330, and the hand hole is closed by the closing valve to realize the rapid filling and replacement of the adsorbent, improve the assembly efficiency of the normal-temperature adsorption device 300, and ensure the use effect of the normal-temperature adsorption device 300.

[0077] In some embodiments, the normal-temperature adsorption device 300 is arranged on the head of the outer tank body 100, so that the normal-temperature adsorption device 300 is arranged obliquely or vertically. The hand hole can be located on the upper side of the normal-temperature adsorption device 300, so that when the staff fills the adsorbent, the adsorbent can quickly enter the storage bin 331 under the action of gravity, improve the filling efficiency, improve the use efficiency of the normal-temperature adsorption device 300, and reduce the contact time of the adsorbent with the external air.

[0078] It can be understood that the normal-temperature adsorption device has two use modes:

[0079] Firstly, the normal-temperature adsorption device 300 can be assembled and completed before the outer tank body 100 and the inner tank body 200 are combined, at this time, the adsorbent has been filled into the storage bin 331. However, this assembly sequence will make the normal-temperature adsorption device 300 absorb part of the air, thereby affecting the use effect of the adsorbent in the actual use process of the vacuum storage tank, and reducing the effective service life of the adsorbent.

[0080] Second, the fixed shaft 310, the rotating body 330 and the clamping member 320 are installed on the outer tank body 100 before the outer tank body 100 and the inner tank body 200 are combined, and then the outer tank body 100 and the inner tank body 200 are combined and assembled. After that, the adsorbent is filled into the storage bin 331 through the hand hole, and then the blocking member 340 is installed. When the multiple storage bins 331 are all filled and blocked, the anti-loosening member 350 is installed. Finally, the hand hole is closed, and the vacuum interlayer 110 is vacuumized. This installation method can effectively reduce the contact time of the adsorbent with air, guarantee the actual adsorption effect of the adsorbent, prolong the service life and reliability of the adsorbent.

[0081] The above embodiments are only illustrative of the structure, and the structures in the embodiments are not fixedly combined. In the absence of structural conflicts, the structures in the multiple embodiments can be arbitrarily combined for use.
