Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] like Figures 1 to 6 As shown, in an embodiment of the present invention, a pressure swing adsorption hydrogen purification device includes an adsorption tower 1, one end of the adsorption tower 1 is fixedly connected to an air inlet pipe 2, a chamber 1 4 and a chamber 2 5 are provided inside the adsorption tower 1, a partition 19 is installed between the chamber 1 4 and the chamber 2 5, the partition 19 is rotatably connected to the adsorption tower 1 through a rotating assembly, and an adsorbent layer 3 is installed on the top and bottom ends of the partition 19, and the two adsorbent layers 3 are respectively arranged inside the chamber 1 4 and the chamber 2 5;

[0031] The rotating assembly includes a first rotating shaft 14 fixedly installed on both sides of the partition 19, one end of which is fixedly connected to a gear 13, and a mounting plate 11 is provided on one side of the gear 13. The mounting plate 11 is slidably installed inside the adsorption tower 1 through the driving assembly, and a gear block 12 is evenly installed on the bottom end of the mounting plate 11.

[0032] Existing: CN221999380U discloses a device for purifying hydrogen by pressure swing adsorption. This patent discloses the adsorption tower 1 and the air inlet pipe 2 proposed in this application document. This technical means will not be described in detail here;

[0033] In operation, the driving assembly drives the mounting plate 11 to move, the mounting plate 11 drives the tooth block 12 to move when moving, the tooth block 12 drives the gear 13 to rotate when engaging with the gear 13, the rotation of the gear 13 drives the rotation of the first rotating shaft 14, the rotation of the first rotating shaft 14 drives the rotation of the partition plate 19, and the rotation of the partition plate 19 drives the rotation of the adsorbent layer 3, so that the partition plate 19 is turned by 180 degrees, the two adsorbent layers 3 in the chamber one 4 and the chamber two 5 are exchanged, the adsorbent layer 3 used for a period of time in the chamber one 4 is removed, and the unused adsorbent layer 3 in the chamber two 5 is moved to the chamber one 4, which not only reduces the complexity of the operation when the adsorbent layer 3 is replaced, but also does not need to be stopped for processing, thereby ensuring the continuous and stable operation of the device.

[0034] As shown in Figures 1 to 6 The driving assembly comprises a gas outlet 28 arranged in the adsorption tower 1, the gas resistance plate 6 is slidably arranged in the gas outlet 28, the first sliding block 7 is fixedly connected to the two sides of the gas resistance plate 6, the first limiting shaft 8 is slidably arranged on the inner wall of the two first sliding blocks 7, the two first limiting shafts 8 are fixedly arranged on the inner wall of the adsorption tower 1, and the first spring 9 is sleeved with the outer part of the two first limiting shafts 8.

[0035] The bottom end of one of the first sliding blocks 7 is fixedly connected with the connecting rod 10, and the connecting rod 10 is arranged at one end of the mounting plate 11.

[0036] The gas resistance plate 6 is slidably attached to the inner wall of the adsorption tower 1, and the inner wall diameter of the gas outlet 28 is greater than that of the gas resistance plate 6;

[0037] The end of the connecting rod 10 close to the mounting plate 11 is magnetically connected with the mounting plate 11, and the two are repulsive.

[0038] In operation, the gas is conveyed to one side of the gas resistance plate 6 after being filtered by the adsorbent layer 3 in the chamber one 4, and the gas resistance plate 6 is pushed into the gas outlet 28 due to the gas pressure, and the gas is discharged from the gas outlet 28;

[0039] At the same time, the movement of the gas resistance plate 6 drives the movement of the first sliding block 7, and the movement of the first sliding block 7 makes the first spring 9 deform to store elastic potential energy;

[0040] When the performance of the adsorbent layer 3 is attenuated due to the decrease of the gas flow after the device is operated for a period of time, the elastic potential energy of the first spring 9 is released to drive the first sliding block 7 to move to one side of the chamber one 4, and the movement of one of the first sliding blocks 7 drives the movement of the connecting rod 10, when one end of the connecting rod 10 moves to one end of the mounting plate 11, the mounting plate 11 is affected by the magnetism to slide away from one end of the connecting rod 10, thereby providing power for the rotating assembly, and the gas pressure in the device itself is used as power, so that the adsorbent life can be accurately matched, and dynamic optimization is realized.

[0041] As shown in Figure 2 , Figure 3 and Figure 5 , the top end and the bottom end of the partition plate 19 are fixedly connected with protrusions 29, and the protrusions 29 are slidingly installed inside the adsorbent layer 3.

[0042] The protrusions 29 are magnetically connected with the gear 13.

[0043] When the adsorbent layer 3 needs to be maintained or replaced, the adsorbent layer 3 can be directly slidingly detached from the outer wall of the protrusions 29, and the maintenance mode is simple and efficient.

[0044] The side of the adsorption tower 1 away from the gear 13 is provided with a detachable maintenance plate, which can be opened for maintenance when the adsorbent layer 3 needs to be replaced or maintained.

[0045] The maintenance plate is located inside the second chamber 5, and the replacement can be realized without stopping.

[0046] As shown in Figure 2 , Figure 3 and Figure 6 , the top end of the mounting plate 11 is fixedly connected with a second sliding block 15, and the second sliding block 15 is slidingly installed on the inner wall of the adsorption tower 1.

[0047] The inner wall of the adsorption tower 1 is provided with a first sliding groove for the second sliding block 15 to slide, and the distance of the movement of the second sliding block 15 is limited by the first sliding groove.

[0048] As shown in Figure 2 , Figure 3 and Figure 6 , the inner wall of the second sliding block 15 is slidingly installed with a second limiting shaft 27, and the outer portion of the second limiting shaft 27 is sleeved with a second spring 16.

[0049] When the air pressure in the first chamber 4 decreases, the second sliding block 15 is driven by the driving assembly to slide on the outer wall of the second limiting shaft 27, so that the nozzle 26 is deformed to store elastic potential energy.

[0050] When the air pressure in the first chamber 4 recovers to normal flow, the second sliding block 15 is moved to reset by the second spring 16 releasing the elastic potential energy.

[0051] As shown in Figure 6 , the gear block 12 is rotatably installed in the inside of the mounting plate 11 through a second rotating shaft 17, and the outer portion of the second rotating shaft 17 is installed with a torsional spring 18.

[0052] The inside of the mounting plate 11 is provided with a second sliding groove for the gear block 12 to rotate, and one side of the gear block 12 is provided in an inclined manner.

[0053] When the installation plate 11 moves back to the original position, the inclined surface of the tooth block 12 contacts the gear 13 and is forced to rotate into the second sliding slot, at this time, the rotation of the tooth block 12 drives the rotation of the second rotating shaft 17, and when the second rotating shaft 17 rotates, the torsional spring 18 deforms to store elastic potential energy. When the tooth block 12 is separated from the gear 13, the elastic potential energy is released by the torsional spring 18 to reset, so that the installation plate 11 does not drive the baffle plate 19 to rotate when it is reset.

[0054] As shown in Figure 2 , Figure 4 and Figure 5 , both ends of the baffle plate 19 are provided with side plates 20.

[0055] The side plates 20 are elastically distributed, such as fluorine rubber or silica gel, which can ensure the sealing between the chamber one 4 and the chamber two 5, and ensure that the gas is adsorbed and discharged from the chamber one 4.

[0056] As shown in Figure 5 , the side plates 20 are uniformly provided with connecting shafts 21 near the baffle plate 19, each connecting shaft 21 is slidingly installed in the inside of the baffle plate 19, and each connecting shaft 21 is provided with a third spring 22 at one end.

[0057] Through the elastic potential energy of the third spring 22, the side plate 20 always has a tendency to move away from the baffle plate 19, so that the end of the side plate 20 is tightly fitted with the inner wall of the adsorption tower 1, further improving the sealing effect and ensuring that the chamber one 4 and the chamber two 5 are completely isolated.

[0058] As shown in Figure 4 , the inner wall of the chamber two 5 is uniformly provided with spray heads 26 on both sides, and each spray head 26 is connected by a connecting pipe 25, one end of the connecting pipe 25 is provided with a water pump 23, and the input end of the water pump 23 is connected with a liquid inlet pipe 24.

[0059] The spray heads 26 are arranged outside the rotation range of the adsorbent layer 3, the baffle plate 19 and the side plate 20;

[0060] The liquid inlet pipe 24 is connected with a water source at the end away from the water pump 23;

[0061] When it is necessary to maintain the adsorbent layer 3 in the chamber two 5 without disassembly, the water pump 23 can be started to draw external water source through the liquid inlet pipe 24, and the water is sprayed from the spray heads 26 to both sides of the adsorbent layer 3 to flush the adsorbent layer 3, and the kinetic energy is used to strip the attached large particle impurities such as dust, rust and polymer, so as to reduce the replacement frequency and maintenance cost.

[0062] As shown in Figure 1 , the inside of the chamber two 5 is embedded with a blowdown pipe 30, and the blowdown pipe 30 is fixedly installed on one side of the adsorption tower 1.

[0063] The electromagnetic valve is installed outside the drain pipe 30 to control the discharge of the cleaning water in the chamber 2.

[0064] Working principle and use process: when working, the gas is filtered by the adsorbent layer 3 in the chamber 1 4 and then transported to one side of the gas resistance plate 6, and the gas resistance plate 6 is pushed into the gas outlet 28 due to the gas pressure, and the gas is discharged from the gas outlet 28;

[0065] Meanwhile, the movement of the gas resistance plate 6 drives the movement of the first sliding block 7, and the deformation of the first spring 9 stores elastic potential energy when the first sliding block 7 moves;

[0066] When the device works for a period of time, the performance of the adsorbent layer 3 deteriorates, resulting in a decrease in gas flow rate, at which time the elastic potential energy of the first spring 9 is released to push the first sliding block 7 to move to one side of the chamber 1 4, and the movement of one of the first sliding blocks 7 drives the movement of the connecting rod 10, when one end of the connecting rod 10 moves to one end of the mounting plate 1 1, the mounting plate 1 1 slides away from one end of the connecting rod 10 due to its magnetic effect, and the movement of the mounting plate 1 1 drives the movement of the tooth block 12, and when the tooth block 12 meshes with the gear 13, the gear 13 rotates, the rotation of the gear 13 drives the rotation of the first rotating shaft 14, the rotation of the first rotating shaft 14 drives the rotation of the partition plate 19, and the rotation of the partition plate 19 drives the rotation of the adsorbent layer 3, so that the partition plate 19 is turned by one hundred and eighty degrees, the two adsorbent layers 3 in the chamber 1 4 and the chamber 2 5 are exchanged, the adsorbent layer 3 used for a period of time in the chamber 1 4 is removed, and the unused adsorbent layer 3 in the chamber 2 5 is moved to the chamber 1 4;

[0067] Meanwhile, the movement of the mounting plate 1 1 drives the sliding of the second sliding block 15 on the outer wall of the second limiting shaft 27, so that the nozzle 26 deforms to store elastic potential energy, and when the gas pressure in the chamber 1 4 returns to normal flow rate, the elastic potential energy is released by the second spring 16 to move the second sliding block 15 to reset;

[0068] When the mounting plate 1 1 moves to reset, the inclined surface of the tooth block 12 contacts the gear 13 to rotate to the second sliding groove, at which time the rotation of the tooth block 12 drives the rotation of the second rotating shaft 17, and when the tooth block 12 is separated from the gear 13, the elastic potential energy is released by the torsional spring 18 to reset, so that the mounting plate 1 1 does not drive the rotation of the partition plate 19 when it resets;

[0069] When it is necessary to maintain the adsorbent layer 3 in the chamber 2 5 without disassembly, the water pump 23 can be started to connect and extract an external water source through the liquid inlet pipe 24, and the water is sprayed from the nozzle 26 to the two sides of the adsorbent layer 3 to flush the adsorbent layer 3, so that the kinetic energy is used to strip the large particle impurities attached to the adsorbent layer 3, and the replacement frequency is reduced;

[0070] When the adsorbent layer 3 needs to be replaced, the adsorption tower 1 is removed from the detachable maintenance plate on the side away from the gear 13, and then the adsorbent layer 3 is directly slid off the outer wall of the protrusion 29, so that the maintenance is simple and efficient, and the replacement is realized without stopping.

[0071] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely divergences of the principles and spirit of the application and that numerous modifications, changes, substitutions, and alterations can be made thereto without departing from the spirit and scope of the application as defined by the appended claims and their equivalents.
