[0020] 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.

[0021] Please see Figure 1-4This utility model provides an embodiment: a highly integrated high-purity helium recovery device for denitrification gas, including an equipment box 2 and a separation tank 12. The front end of the equipment box 2 is provided with a front cover 4. The separation tank 12 is vertically installed on the right side inside the equipment box 2. Connecting brackets 7 are fixed on both sides of the top of the equipment box 2. Connecting feet 8 are fixed on both sides of the top of the front cover 4. The connecting feet 8 are hinged to the inside of the connecting brackets 7. Fixing feet 18 are fixed on both sides of the bottom front end of the front cover 4, and locking rods 19 are provided at the front end of the fixing feet 18. Threaded holes 21 are opened on both sides of the bottom front end of the equipment box 2. A handle 20 is fixed at the middle position of the bottom front end of the front cover 4. A control panel 6 is installed on the top left side of the front end of the front cover 4, and an LED light 9 is provided at the bottom of the control panel 6.

[0022] The locking rod 19 has external threads on its exterior, and the rear end of the locking rod 19 passes through the interior of the fixing foot 18 and is threaded into the threaded hole 21.

[0023] Specifically, such as Figure 1 and Figure 2 As shown, during the installation and use of the recycling equipment, when performing maintenance operations on the internal components, the locking rod 19 is turned forward from the threaded hole 21 on the fixing feet 18 on both sides of the bottom front of the front cover 4. This unlocks the front cover 4 at the front of the equipment box 2. Then, by lifting the handle 20 and using the hinge between the connecting foot 8 and the connecting frame 7, the front cover 4 can be flipped backward, opening the interior of the equipment to a large area. This reduces the operational limitations caused by the small space and allows for convenient maintenance operations on the internal components of the recycling equipment.

[0024] The top of the inside of the equipment box 2 is provided with a gooseneck tube 10, and an LED light 9 is installed and fixed on the left side of the gooseneck tube 10. A mounting foot 22 is fixed on the right side of the gooseneck tube 10. A switch 23 is installed and fixed on the right side of the top of the inside of the equipment box 2. The top of the mounting foot 22 is installed and fixed to the top of the inside of the equipment box 2. The LED light 9 is electrically connected to the switch 23.

[0025] Furthermore, the inside of the gooseneck tube 10 is composed of multiple layers of corrugated metal tubes or elastic materials, which allows the tube to undergo elastic deformation when subjected to force, thereby achieving multi-angle bending. This is a publicly available prior art, so it will not be described in detail.

[0026] Specifically, such as Figure 1 and Figure 3 As shown, during internal maintenance operations of the recycling equipment, the LED lighting lamp 9 is powered on by turning on switch 23. The LED lighting lamp 9 can illuminate the maintenance operation area inside the equipment, assisting in the maintenance operation. At the same time, the lighting position of the LED lighting lamp 9 can be adjusted by bending the gooseneck tube 10.

[0027] The front end of the control panel 6 is provided with a cover 5, and the top two sides of the cover 5 are respectively fixed with connecting feet 25. The top left side of the front cover 4 is fixed with two sets of connecting brackets 24. The connecting feet 25 and the interior of the connecting brackets 24 are hinged. The bottom end of the cover 5 is fixed with a protruding handle.

[0028] Furthermore, the cover 5 is made of transparent acrylic material;

[0029] Specifically, such as Figure 1 and Figure 4 As shown, a cover 5 is installed on the outside of the control components at the front end of the equipment. The cover 5 can be used to cover the outside of the control panel 6 and the LED lighting 9 to prevent accidental operation.

[0030] A compressor 3 is installed on the left side inside the equipment box 2, and a gas inlet pipe 1 is installed at the input end of the compressor 3. The left side of the gas inlet pipe 1 penetrates the interior of the left side of the equipment box 2. A gas outlet pipe 17 is installed at the output end of the compressor 3. An air inlet pipe 15 is installed and fixed at the bottom left side of the separator 12. Two sets of filters 16 are installed between the gas outlet pipe 17 and the air inlet pipe 15. Several hollow fiber membranes 13 are installed inside the separator 12. An air outlet pipe 11 is installed and fixed at the top of the separator 12, and the right side of the air outlet pipe 11 penetrates the interior of the right side of the equipment box 2. An air outlet pipe 2 14 is installed and fixed at the bottom of the separator 12, and the right side of the air outlet pipe 2 14 penetrates the interior of the right side of the equipment box 2.

[0031] Working Principle: During operation, nitrogen gas enters the equipment through the gas inlet pipe 1, is pressurized in the compressor 3, and then exits through the gas outlet pipe 17. After passing through the filter 16 to remove water and oil, it enters the separation tank 12. Because helium molecules are smaller and diffuse faster than nitrogen molecules, they can more easily pass through the micropores or pores in the hollow fiber membrane 13 material inside the separation tank 12. Nitrogen gas is retained due to its larger molecular size and weaker permeability. Under pressure, the mixed gas passes through the hollow fiber membrane 13 module, with helium preferentially permeating through the membrane wall, while nitrogen gas is enriched on the retention side. The equipment box 2, front cover 4, connecting frame 7, connecting foot 8, fixing foot 18, locking rod 19, handle 20, and threaded hole 21 are all included. During the installation and use of the recycling equipment, when performing maintenance operations on the internal components, the locking rod 19 is screwed forward from the threaded hole 21 onto the fixing feet 18 on both sides of the front bottom of the front cover 4. This unlocks the front cover 4 at the front of the equipment box 2. Then, by lifting the handle 20 and using the hinge between the connecting foot 8 and the connecting frame 7, the front cover 4 can be flipped backward, opening the interior of the equipment for convenient maintenance operations on the internal components. Simultaneously, during maintenance operations, the LED light 9 is powered on by turning on the switch 23, illuminating the maintenance area and assisting in the maintenance process. The position of the LED light 9 can also be adjusted by bending the gooseneck tube 10. Furthermore, during equipment installation and use, a cover 5 is installed on the outside of the control components at the front of the equipment. The cover 5 can be used to cover the outside of the control panel 6 and the LED lighting 9 to prevent accidental operation.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
