[0037] See also Figures 2 to 5 The present application provides a room temperature adsorption device 300, which is accommodated in the vacuum interlayer 110 of the vacuum storage tank. The room temperature adsorption device 300 includes: a fixed shaft 310, a rotating body 330 and a blocking member 340. The fixed shaft 310 is used to be fixedly connected to the vacuum storage tank. The rotating body 330 is rotatably sleeved on the fixed shaft 310. A storage bin 331 for accommodating an adsorbent is provided in the rotating body 330, and the storage bin 331 extends around the circumference of the fixed shaft 310. A delivery port 332 is provided on the outer peripheral wall of the rotating body 330, and the delivery port 332 is connected to the storage bin 331. A plurality of vents 333 are provided on the rotating body 330, and the plurality of vents 333 are connected to the storage bin 331 and the vacuum interlayer 110. The blocking member 340 is detachably provided on the delivery port 332 of the rotating body 330 so as to be able to block the delivery port 332.

[0038] When the room temperature adsorption device 300 is used, the fixed shaft 310 is first 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.

[0039] When the staff fills the adsorbent, they rotate the rotating body 330 so that they can quickly and accurately select the delivery port 332 and deliver the adsorbent into the storage bin 331 through the delivery port 332. Afterwards, the delivery port 332 is blocked by the blocking member 340 to fill the adsorbent into the storage bin 331, thereby achieving rapid delivery and use of the adsorbent, effectively improving the assembly efficiency and use efficiency of the room temperature adsorption device 300. In addition, it can also effectively reduce the contact time between the adsorbent and the external environment, ensuring the adsorption effect and service life of the adsorbent.

[0040] See also Figures 3 to 5 In this 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 prevent the normal temperature adsorption device 300 from falling off. The fixed shaft 310 can also transfer the heat in the rotating body 330 to the outer tank body 100.

[0041] A limiting portion 311 is convexly provided on the outer periphery of the fixed shaft 310. A clamping member 320 is detachably provided on the fixed shaft 310, and the clamping member 320 is detachably connected to 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 also facilitating the rotating body 330 to rotate around the fixed shaft 310 to fill the adsorbent, thereby improving the assembly efficiency and use efficiency of the normal temperature adsorption device 300.

[0042] In some embodiments, the limiting portion 311 is arranged in a ring shape along the outer circumference of the fixed shaft 310, so as to effectively increase the contact area between the limiting portion 311 and the rotating body 330, facilitate the rotation of the rotating body 330, and improve the connection strength and reliability between the limiting portion 311 and the rotating body 330.

[0043] 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, so that the fixed shaft 310 and the limiting portion 311 form a concentric cylindrical structure, thereby increasing the contact area between the fixed shaft 310 and the outer tank body 100, thereby increasing the connection strength and reliability between the fixed shaft 310 and the outer tank body 100.

[0044] See also Figures 3 to 5 In this embodiment, a snap-fit ​​groove 312 is recessed at the free end of the fixed shaft 310, and the snap-fit ​​groove 312 is annularly arranged along the circumference of the fixed shaft 310. The snap-fit ​​member 320 is an elastic snap-fit ​​member 320, which can be sleeved on the fixed shaft 310 and can be limited in the snap-fit ​​groove 312, so that the snap-fit ​​member 320 can be accommodated and limited in the snap-fit ​​groove 312, thereby limiting the end of the rotating body 330 away from the limiting portion 311, which is convenient for the installation and disassembly of the normal temperature adsorption device 300.

[0045] It can be understood that when the fixed shaft 310 is connected to 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 .

[0046] In some embodiments, the engaging 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 engaging groove 312 and elastically shrink to be embedded in the engaging groove 312, so that the elastic retaining ring can respectively abut the rotating body 330 with the limiting portion 311, and limit the movement and swaying of the rotating body 330 along the axial direction of the fixed shaft 310. The engaging groove 312 and the elastic retaining ring can realize the rapid assembly of the normal temperature adsorption device 300, and improve the assembly efficiency and reliability of the normal temperature adsorption device 300.

[0047] In other embodiments, the free end of the fixed shaft 310 may be provided with a clamping hole, and the axial direction of the clamping hole is perpendicular to the axial direction of the fixed shaft 310. The clamping member 320 may be a clamping pin or a clamping bolt, which is detachably provided in the clamping hole of the fixed shaft 310, so as to resist and limit the movement and swaying of the rotating body 330 along the fixed shaft 310.

[0048] See also Figures 3 to 5 In this embodiment, the fixed shaft 310 and the outer tank body 100 can be welded to improve the connection strength between the fixed shaft 310 and the outer tank body 100, overcome the mutual influence of thermal expansion and contraction of the outer tank body 100 and the fixed shaft 310, and improve the reliability and stability between the room temperature adsorption device 300 and the outer tank body 100.

[0049] In some embodiments, the material of the fixed shaft 310 may 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 may also be non-alloy steel.

[0050] See also Figures 3 to 5 In this embodiment, the rotating body 330 can be cylindrical, and the axis of the rotating body 330 is coaxial with the axis of the fixed shaft 310, so that the staff can rotate the rotating body 330.

[0051] A rotating hole is provided in the middle of the rotating body 330, 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. After the rotating body 330 is sleeved on the fixed shaft 310, the rotating body 330 is located between the limiting portion 311 and the engaging member 320 to prevent the rotating body 330 from moving along the fixed shaft 310 during the transportation of the vacuum storage tank.

[0052] In some embodiments, the rotating body 330 may be a prismatic structure.

[0053] See also Figures 3 to 5 In this embodiment, a storage bin 331 for accommodating the adsorbent is provided in the rotating body 330 to facilitate the storage and replacement of the adsorbent and improve the use efficiency of the normal temperature adsorption device 300.

[0054] In some embodiments, a plurality of storage bins 331 may 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 sequentially arranged around the fixed axis 310. Each storage bin 331 is provided with at least one delivery port 332 to facilitate delivery and replacement of the adsorbent, thereby improving the assembly efficiency and use efficiency of the room temperature adsorption device 300.

[0055] The rotating body 330 is provided with a plurality of storage bins 331, and the adsorbent can be split and placed in the plurality of storage bins 331 respectively. The adsorbent can be used to adsorb gases such as hydrogen and nitrogen in the vacuum interlayer 110. The adsorbent generates heat when adsorbing the gas in the vacuum interlayer 110. Separating the adsorbent for storage can, on the one hand, reduce the stacking of the adsorbent and increase the actual adsorption area; on the other hand, it can avoid the transfer and concentration of heat, thereby avoiding the rapid increase of temperature and causing a chain reaction, reducing the chemical reaction rate, and improving the heat insulation effect of the vacuum interlayer 110.

[0056] Moreover, after the separately stored adsorbent 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, thereby further reducing the influence of the heat generated when the adsorbent adsorbs gas on the vacuum interlayer 110, thereby ensuring the cold preservation effect of the vacuum storage tank.

[0057] In other embodiments, the plurality of storage bins 331 can also be used to respectively charge different types of adsorbents, thereby increasing the operability of the room temperature adsorption device 300 and improving the scope of application of the room temperature adsorption device 300 .

[0058] In other embodiments, an outer peripheral wall of the rotating body 330 is provided with a delivery port 332 relative to a storage bin 331 to enable delivery and replacement of the adsorbent.

[0059] See also Figures 3 to 5 In this embodiment, a plurality of vent holes 333 are provided on the opposite side walls of the rotating body 330 along the axial direction of the fixed shaft 310, so as to facilitate the reaction between the adsorbent and the gas in the vacuum interlayer 110 and improve the adsorption effect of the adsorbent.

[0060] In some embodiments, the diameter of the vent hole 333 is less than 1.5 mm, thereby effectively preventing the adsorbent from falling into the vacuum interlayer 110 through the vent hole 333, thereby facilitating the storage and replacement of the adsorbent.

[0061] In some embodiments, the material of the rotating body 330 can be steel.

[0062] In other embodiments, the rotating body 330 may 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 both annular, and the two end plates 3343 are respectively located at the two ends of the axis of the outer cylinder 3341 to seal and fit the outer cylinder 3341 and the inner cylinder 3342 respectively. The outer cylinder 3341, the inner cylinder 3342 and the two end plates 3343 enclose a chamber. A plurality of partition plates 3344 are accommodated in the chamber at intervals, and the plurality of partition plates 3344 extend along the radial direction of the outer cylinder 3341 to separate the chamber into a plurality of storage bins 331. A delivery port 332 is respectively provided on the outer cylinder 3341 relative to the plurality of storage bins 331. A plurality of ventilation holes 333 are formed on both end plates 3343 .

[0063] See also Figures 3 to 5 In this embodiment, the blocking member 340 is detachably connected to the delivery port 332 of the rotating body 330 to facilitate the delivery and replacement of the adsorbent.

[0064] In some embodiments, the blocking member 340 is threadedly connected to the rotating body 330, thereby improving 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.

[0065] Figure 6 yes Figure 5 Schematic diagram of the structure after the anti-loosening parts are installed in the structure shown in.

[0066] See also Figures 3 to 6 In this embodiment, the blocking member 340 is provided with an anti-loosening hole 341 at one end outside the rotating body 330. The normal temperature adsorption device 300 further includes an anti-loosening member 350, which can be detachably inserted into the anti-loosening hole 341 of the blocking member 340 to limit the blocking member 340 on the rotating body 330, prevent the blocking member 340 from rotating and loosening, and improve the connection strength and reliability between the blocking member 340 and the rotating body 330.

[0067] In some embodiments, the anti-loosening hole 341 extends perpendicular to the extending direction of the blocking member 340. The anti-loosening member 350 connects at least two blocking members 340 to limit the blocking members 340 on the rotating body 330, thereby improving the assembly and disassembly efficiency between the anti-loosening member 350 and the blocking members 340.

[0068] In other embodiments, the anti-loosening member 350 may be an anti-loosening steel wire, which can extend along the circumference of the rotating body 330 to penetrate 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 to prevent the blocking members 340 from rotating due to thermal expansion and contraction, vibration, etc., and to prevent the blocking members 340 from loosening and falling out of the rotating body 330.

[0069] When the staff needs to disassemble the blocking member 340 to replace the adsorbent, all the blocking members 340 can be unlocked by removing the anti-loosening member 350 , thereby effectively improving the assembly and disassembly efficiency of the normal temperature adsorption device 300 .

[0070] In other embodiments, the diameter of the anti-loosening steel wire may be a stainless steel wire of φ1mm to φ1.5mm.

[0071] In other embodiments, the anti-loosening member 350 may also be a bolt, a clamp, etc., as long as it can prevent the blocking member 340 from falling off the rotating body 330 when the normal temperature adsorption device 300 is in use.

[0072] See also Figures 1 to 6 The present application provides a room temperature adsorption device 300, which can be fixedly connected to the outer tank body 100. When the room 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 engaging member 320 is engaged in the engaging groove 312, so that the limiting portion 311 and the engaging member 320 respectively abut against the two side walls of the rotating body 330 along the axial direction of the fixed shaft 310.

[0073] Afterwards, one or more adsorbents are respectively filled into the multiple storage bins 331, and then blocked in the delivery port 332 by the blocking member 340 to limit the adsorbent in the storage bin 331. Finally, the anti-loosening member 350 is passed through the anti-loosening holes 341 of the multiple blocking members 340 to limit the rotation of the blocking member 340. The normal temperature adsorption device 300 has high assembly efficiency, effectively reduces the contact time between the adsorbent and the external environment, and ensures the adsorption effect and service life of the adsorbent.

[0074] Moreover, on the one hand, the adsorbent can absorb the gas in the vacuum interlayer 110, thereby improving the cold-keeping effect of the vacuum interlayer 110; on the other hand, the heat generated by the adsorbent when absorbing the gas can also be transferred to the outer tank body 100 through the rotating body 330 and the fixed shaft 310, thereby reducing the influence of the heat generated by the adsorbent on the inner tank body 200 and improving the cold-keeping effect of the vacuum storage tank.

[0075] See also Figures 1 to 6The present application also provides a vacuum storage tank, which includes: an outer tank body 100, an inner tank body 200 and any one of the above normal temperature adsorption devices 300. 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.

[0076] 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.

[0077] In this embodiment, the outer tank body 100 is provided with a hand hole (not shown) on the peripheral side of the room temperature adsorption device 300. The vacuum storage tank further includes a closing valve, which is detachably arranged on the hand hole to block the hand hole.

[0078] When the room temperature adsorption device 300 needs to be filled or replaced with adsorbent, the staff can open the closing valve and then remove the anti-loosening member 350 and the blocking member 340 by the closing method to fill the adsorbent into the storage bin 331 or replace the adsorbent in the storage bin 331. Afterwards, the blocking member 340 and the anti-loosening member 350 are assembled on the rotating body 330, and then 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 room temperature adsorption device 300, and ensure the use effect of the room temperature adsorption device 300.

[0079] In some embodiments, the room temperature adsorption device 300 is disposed on the end cap of the outer tank 100 so that the room temperature adsorption device 300 is tilted or vertically disposed. The hand hole can be located on the upper side of the room 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, thereby improving the filling efficiency, improving the use efficiency of the room temperature adsorption device 300, and reducing the contact time between the adsorbent and the outside air.

[0082] The outer tank body 100 is provided with a hand hole on the side of the room temperature adsorption device 300. The installation method includes:

[0083] Step S100 , the room temperature adsorption device 300 is fixedly connected to the outer tank body 100 .

[0084] In step S200, after the outer tank body 100 is sleeved on the inner tank body 200, the adsorbent is filled into the room temperature adsorption device 300 through the hand hole.

[0085] On the one hand, the room temperature adsorption device 300 also has an installation method: the room temperature adsorption device 300 can be assembled before the outer tank body 100 and the inner tank body 200 are assembled, and at this time, the adsorbent has been filled in the storage bin 331. However, this assembly sequence will cause the room temperature adsorption device 300 to absorb part of the air, thereby affecting the use effect of the adsorbent during the actual use of the vacuum storage tank and reducing the effective service life of the adsorbent.

[0086] On the other hand, the room temperature adsorption device 300 also has another installation method: before the outer tank body 100 and the inner tank body 200 are assembled, the fixed shaft 310, the rotating body 330 and the engaging member 320 are first installed on the outer tank body 100, and then the outer tank body 100 and the inner tank body 200 are assembled. After that, the adsorbent is filled into the storage bin 331 through the hand hole and the blocking member 340 is installed. When the multiple storage bins 331 are filled and blocked, the anti-loosening member 350 is installed. Finally, the hand hole is closed to evacuate the vacuum interlayer 110.

[0087] This installation method enables the adsorbent to effectively reduce its contact time with air, ensure the actual adsorption effect of the adsorbent, and extend the service life and reliability of the adsorbent.

[0088] In this embodiment, the step S200 of the method for installing the room temperature adsorption device 300 further includes a step S210.

[0089] The blocking member 340 is provided with an anti-loosening hole 341 . The normal temperature adsorption device 300 further includes an anti-loosening member 350 .

[0090] Step S210, after the adsorbent is filled into the storage bin 331 through the hand hole, the blocking member 340 blocks the delivery port 332; after the multiple storage bins 331 are filled, the anti-loosening member 350 passes through the anti-loosening holes 341 of the multiple blocking members 340 in sequence.

[0091] After the multiple storage bins 331 in the rotating body 330 are filled, the blocking member 340 is installed, and the anti-loosening member 350 passes through the multiple anti-loosening holes 341 in sequence, so as to effectively limit the multiple blocking members 340 and prevent the multiple blocking members 340 from loosening due to thermal expansion and contraction. In addition, the staff only needs to remove one loosening wire to unlock all the blocking members 340, so as to improve the assembly and disassembly efficiency of the normal temperature adsorption device 300, facilitate the subsequent adsorbent replacement, and reduce the adsorbent replacement time.
