Description

Technical Field

[0001] This utility model relates to the field of cryogenic hydrogen separation and storage technology, specifically a storage tank for cryogenic hydrogen separation and purification. Background Technology

[0002] Hydrogen energy, the chemical energy released from the chemical reaction of hydrogen and oxygen, is a secondary clean energy source. Accelerating its development and utilization is crucial for its sustainable development. Hydrogen energy can also be used in hydrogen-powered vehicles. In hydrogen-powered vehicles, the chemical energy produced by the hydrogen reaction is converted into mechanical energy to propel the vehicle, significantly reducing environmental pollution compared to gasoline-powered vehicles. According to automotive hydrogen standards, the hydrogen used in hydrogen-powered vehicles must meet certain standards. Hydrogen purification involves complex processes, often using membrane separation and adsorption methods. However, the lifespan of polymer membranes and molecular sieves is limited, and prolonged operation can affect the quality of hydrogen purification. Low-temperature condensation purification addresses this by using staged refrigeration based on the composition of the mixed gas, liquefying and separating the gases. This allows for continuous and stable hydrogen purification, ensuring the quality of the purified hydrogen.

[0003] No effective solutions have yet been proposed to address the problems in the relevant technologies.

[0004] 1. Existing cryogenic separation hydrogen purification storage tanks have poor sealing performance during use, which may lead to hydrogen leakage during storage. This makes it difficult to store hydrogen effectively and causes many inconveniences for staff. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a storage tank for cryogenic separation and hydrogen purification to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A storage tank for cryogenic separation and hydrogen purification includes a tank body, a tank cover, and a stop assembly. The tank cover is threadedly engaged with the upper end of the tank body. Support frames are fixedly connected to the upper ends of both sides of the tank body. The stop assembly includes a stop block, which is slidably connected to the inside of the support frame. A return spring is fixedly connected to one end of the stop block. Support blocks are fixedly connected to both sides of the tank cover.

[0008] A further improvement of this utility model is that: the support frame has an internal movable groove, the stop block is slidably connected to the inside of the movable groove, and the end of the return spring away from the stop block is fixedly connected to the inner wall of the movable groove.

[0009] Using the above technical solution, the reset spring can drive the stop block to perform a reset movement, so that the stop block returns to its original position, thereby blocking the support block and limiting the can lid so that it will not loosen and leak air.

[0010] A further improvement of this utility model is that: a limiting groove is provided on both sides of the inner wall of the movable groove, and a limiting block is fixedly connected to both sides of the stop block, and the limiting block and the limiting groove are compatible.

[0011] A further improvement of this utility model is that the limiting block is slidably connected to the inside of the limiting groove, and the stop block is slidably connected to the inside of the movable groove through the limiting block and the limiting groove.

[0012] Using the above technical solution, the limiting block and limiting groove in the solution can limit the stop block, so that the stop block will not fall out of the movable groove.

[0013] A further improvement of this utility model is that: the upper outer wall of the tank body is provided with a first thread pattern, the inner wall of the tank cover is provided with a second thread pattern, and the tank cover is threadedly engaged with the tank body through the first thread pattern, the second thread pattern, and the threaded connection between them.

[0014] A further improvement of the present invention is that: a first inclined surface is provided on one side of the support block, and a second inclined surface is provided at the end of the stop block away from the reset spring.

[0015] In the above technical solution, the first and second inclined surfaces are used to rub against each other, so that the stop block slides inside the movable groove under the thrust of friction, thereby facilitating the support block to pass through the stop block.

[0016] A further improvement of this utility model is that: a second sealing gasket is fixedly connected to the inner upper wall of the can lid, and a first sealing gasket is fixedly connected to the upper end of the can body.

[0017] By adopting the above technical solution, the first and second sealing gaskets in the solution can further ensure the sealing performance of the can lid.

[0018] A further improvement of this utility model is that: a pull rod is fixedly connected to one end of the stop block, and a through groove communicating with the movable groove is opened on one side of the support frame, and the pull rod is slidably connected inside the through groove.

[0019] Using the above technical solution, the pull rod can be pulled, and pulling the pull rod will cause the stop block to slide, so that the stop block no longer obstructs the support block, thus making it easier to open the can lid and facilitate the operation of the staff.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. By screwing on the can lid, the reset spring can drive the stop block to reset, so that the stop block returns to its original position, thereby blocking the support block and limiting the can lid to prevent it from loosening and leaking air, thus ensuring the sealing between the can body and the can lid.

[0022] 2. Pulling the lever will cause the stop block to slide, so that the stop block no longer obstructs the support block, making it easier to open the can lid. This facilitates operation by staff and provides both a seal and easy opening. Attached Figure Description

Detailed Implementation

[0030] 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.

[0031] According to an embodiment of the present invention, a storage tank for cryogenic separation and hydrogen purification is provided.

[0032] Example 1;

[0033] like Figure 1-4 As shown, the storage tank for cryogenic separation and hydrogen purification according to an embodiment of the present invention includes a tank body 1, a tank cover 2, and a blocking component 3. The tank cover 2 is threadedly engaged with the upper end of the tank body 1. Support frames 103 are fixedly connected to the upper ends of both sides of the tank body 1. The blocking component 3 includes a stop block 301, which is slidably connected to the inside of the support frame 103. A return spring 303 is fixedly connected to one end of the stop block 301. Support blocks 203 are fixedly connected to both sides of the tank cover 2.

[0034] In this embodiment, by screwing on the can lid 2, the reset spring 303 can drive the stop block 301 to perform a reset movement, so that the stop block 301 returns to its original position, thereby blocking the support block 203 and limiting the can lid 2 so that it will not loosen and leak air, thus ensuring the sealing between the can body 1 and the can lid 2.

[0035] Example 2;

[0036] like Figure 1-4 As shown, in the cryogenic separation hydrogen purification storage tank according to an embodiment of the present invention, the support frame 103 has an internal movable groove 104, a stop block 301 is slidably connected to the inside of the movable groove 104, and the end of the return spring 303 away from the stop block 301 is fixedly connected to the inner wall of the movable groove 104. Limiting grooves 105 are provided on both sides of the inner wall of the movable groove 104, and limiting blocks 304 are fixedly connected to both sides of the stop block 301. The limiting blocks 304 and the limiting grooves 105 are adapted to each other, and the limiting blocks 304 are slidably connected to the inside of the limiting grooves 105. The stop block 301 is slidably connected to the inside of the movable groove 104 through the limiting blocks 304 and the limiting grooves 105.

[0037] In this embodiment, the reset spring 303 can drive the stop block 301 to perform a reset movement, so that the stop block 301 returns to its original position, thereby blocking the support block 203 and limiting the can lid 2 to prevent it from loosening and causing air leakage. The limiting block 304 and the limiting groove 105 can limit the stop block 301 so that the stop block 301 will not disengage from the movable groove 104.

[0038] Example 3;

[0039] like Figure 1-4As shown, according to an embodiment of the present invention, a storage tank for cryogenic separation and hydrogen purification has a first thread 101 on the upper outer wall of the tank body 1 and a second thread 202 on the inner wall of the tank cover 2. The tank cover 2 is threaded together with the tank body 1 through the first thread 101, the second thread 202, and the first inclined surface 204 on one side of the support block 203. The end of the stop block 301 away from the return spring 303 has a second inclined surface 302. A second sealing gasket 201 is fixedly connected to the inner upper wall of the tank cover 2. A first sealing gasket 102 is fixedly connected to the upper end of the tank body 1. A pull rod 305 is fixedly connected to one end of the stop block 301. A through groove communicating with the movable groove 104 is opened on one side of the support frame 103. The pull rod 305 is slidably connected to the inside of the through groove.

[0040] In this embodiment, the first inclined surface 204 and the second inclined surface 302 are used for mutual friction, so that the stop block 301 slides inside the movable groove 104 under the thrust of friction, thereby facilitating the support block 203 to pass through the stop block 301. The first sealing gasket 102 and the second sealing gasket 201 can further ensure the sealing of the can lid 2. The pull rod 305 can be pulled, and pulling the pull rod 305 will drive the stop block 301 to slide, so that the stop block 301 no longer blocks the support block 203, thereby facilitating the opening of the can lid 2 and making it convenient for the operator to operate.

[0041] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0042] In practical applications, when the can lid 2 is screwed on, the first inclined surface 204 and the second inclined surface 302 will rub against each other during the screwing process. This causes the stop block 301 to slide inside the movable groove 104 under the thrust of friction, which in turn compresses the return spring 303. When the support block 203 passes the stop block 301, the compressed return spring 303 can drive the stop block 301 to perform a reset movement, causing the stop block 301 to return to its original position, thereby blocking the support block 203 and limiting the can lid 2. This tightly connects the can body 1 and the can lid 2 together. When the can lid 2 needs to be opened, pulling the lever 305 will cause the stop block 301 to slide, so that the stop block 301 no longer blocks the support block 203. Rotating the can lid 2 will open the can lid 2.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
