The use of the pressure sensor enables a certain degree of automation in the hydrogen generator filter. When the pressure reaches the set value, hydraulic rod 1 automatically stops extending, eliminating the need for manual continuous monitoring and adjustment. This solves the problem of ensuring the secure installation of the filter element and improves the safety and automation of the hydrogen generator filter.

The cotton wool is used to remove tiny solid particles or droplets that may exist in the hydrogen to avoid damaging the hydrogen. The generator filter and hydrogen-using equipment will be damaged, and the purity of the hydrogen will also be affected. Activated carbon particles are used to further remove trace impurities remaining in the hydrogen, including organic solvents, organic gases and sulfides.

[0073] A hydraulic rod 20 is connected to the top wall of the filter sealing cover 19, and the output end of the hydraulic rod 20 is connected to the movable plate 21. The movable plate 21 is driven to move up and down by the extension and contraction of the hydraulic rod 20. The T-shaped pressure rods 22 are evenly arranged at the bottom of the movable plate 21 and move up and down together with the movable plate 21. The bottom of the T-shaped pressure rod 22 is connected with an anti-slip gasket 1 to ensure that it is stable and anti-slip when the filter element replacement module is pressed, thereby improving the stability and safety of the filter. The sliding block 23 is installed on the side wall of the filter body 1 and is provided with a slide groove 24 inside. The two ends of the movable plate 21 are located inside the slide groove 24 to ensure that the movable plate 21 remains stable and the direction is accurate when moving up and down;

[0074] The pressure sensor 10 is located above the filter element replacement module and is used to detect the pressure applied by the T-shaped pressure rod 22 and the anti-slip pad to the top plate 9. The output end of the pressure sensor 10 is connected to the controller to achieve real-time monitoring and adjustment of the pressing force of the filter element replacement module to prevent the filter element from loosening due to insufficient pressing force or damaging the filter element due to excessive pressing force;

[0075] When the filter element needs to be replaced, the hydraulic rod 20 is controlled to retract, so that the T-shaped pressure rod 22 rises and the pressing force on the filter element replacement module is released. At this time, the staff can easily take out the filter element replacement module for replacement. After the replacement is completed, the hydraulic rod 20 is controlled to extend again, so that the T-shaped pressure rod 22 descends and applies appropriate pressing force to the new filter element replacement module through the anti-slip gasket pair.

[0076] See also Figure 9 The present invention provides an embodiment: a hydrogen generator filter that is easy to assemble and disassemble, the fastening and pressing module may include a hydraulic rod 25 connected to the top wall of the filter sealing cover 19, the output end of the hydraulic rod 25 is connected to a U-shaped pressure rod 26, the bottom of the U-shaped pressure rod 26 is connected to an anti-slip gasket 2, and the bottom of the anti-slip gasket 2 is in contact with the top of the top plate 9, and the anti-slip gasket 2 is located above the pressure sensor 10.

[0077] Furthermore, the second hydraulic rod 25 is connected to the top wall of the filter sealing cover 19. By controlling the extension and contraction of the second hydraulic rod 25, the filter element replacement module can be pressed or released. The output end of the U-shaped pressure rod 26 is connected to the U-shaped pressure rod 26. The design of the U-shaped pressure rod 26 enables it to evenly distribute pressure on the top plate 9 of the filter element replacement module to prevent local excessive pressure from causing damage to the filter element. The bottom of the U-shaped pressure rod 26 is connected to the second anti-slip gasket, which ensures that no sliding occurs when the filter element replacement module is pressed, thereby improving stability.

[0078] The pressure sensor 10 is located above the filter element replacement module and below the second anti-slip pad. It is used to detect the pressure applied by the U-shaped pressure rod 26 to the top plate 9 through the second anti-slip pad. The output end of the pressure sensor 10 is connected to the controller to achieve real-time monitoring and adjustment of the pressing force of the filter element replacement module to avoid loosening of the filter element due to insufficient pressing force or damage to the filter element due to excessive pressing force.

[0079] When the filter element needs to be replaced, the hydraulic rod 25 is controlled to contract, so that the U-shaped pressure rod 26 rises and the pressing force on the filter element replacement module is released. At this time, the staff can easily take out the filter element replacement module for replacement. After the replacement is completed, the hydraulic rod 25 is controlled to extend again, so that the U-shaped pressure rod 26 descends and applies appropriate pressing force to the new filter element replacement module through the anti-slip gasket 2.

[0080] Further, the filter is used as follows:

[0081] S1, after hydrogen enters the filter body 1 from the air inlet 16, it passes through the silica gel desiccant, the corrugated activated carbon adsorption plate 18, the molecular sieve adsorbent, the corrugated activated carbon adsorption plate 18, the absorbent cotton, the corrugated activated carbon adsorption plate 18 and the activated carbon particles in sequence for adsorption and filtration, and then the gas is discharged from the air outlet 17;

[0082] S2. When the filter element needs to be replaced, it can be replaced through the filter element replacement module.

[0083] Furthermore, in S2, the following steps are also included:

[0084] S21, the gravity sensor 15 detects the weight of the filter element replacement module. When the detection result exceeds the set safety value, it indicates that the filter element inside the filter element replacement module has failed and needs to be replaced;

[0085] S22. Use handle 1 to vertically remove the top plate 9 and the fixed frame 1 8 at its bottom from the interior of the filter body 1. Then use handle 2 to horizontally remove the fixed frame 2 11, the stainless steel mesh 12, and the filter element from the interior of the fixed frame 8. Remove the failed filter element and replace the new filter element with the fixed frame 2 11 and the stainless steel mesh 12.

[0086] S23. Install the fixed frame 2 11, the stainless steel mesh 12 and the filter element therein horizontally into the interior of the fixed frame 1 8, and vertically install the top plate 9 and the bottom fixed frame 1 8 into the interior of the filter body 1 through the handle 1.

[0087] Working principle: After hydrogen enters the filter body 1 from the air inlet 16, it is adsorbed and filtered by the silica gel desiccant, the corrugated activated carbon adsorption plate 18, the molecular sieve adsorbent, the corrugated activated carbon adsorption plate 18, the absorbent cotton, the corrugated activated carbon adsorption plate 18 and the activated carbon particles in sequence, and then the gas is discharged from the air outlet 17;

[0088] The gravity sensor 15 detects the weight of the filter element replacement module. When the detection result exceeds the set safety value, it indicates that the filter element inside the filter element replacement module has failed and needs to be replaced.

[0089] When the filter element needs to be replaced, the hydraulic rod 1 20 is controlled to retract, so that the T-shaped pressure rod 22 rises and the pressing force on the filter element replacement module is released. Alternatively, the hydraulic rod 25 is controlled to retract, so that the U-shaped pressure rod 26 rises and the pressing force on the filter element replacement module is released. At this time, the staff can easily take out the filter element replacement module for replacement.

[0090] Use handle 1 to vertically remove the top plate 9 and the fixed frame 1 8 at its bottom from the inside of the filter body 1, then use handle 2 to horizontally remove the fixed frame 2 11, the stainless steel mesh 12 and the filter element from the inside of the fixed frame 8, dump out the failed filter element, and install a new filter element into the fixed frame 2 11 and the stainless steel mesh 12;

[0091] Install the fixed frame 2 11, the stainless steel mesh 12 and the filter element inside it horizontally into the interior of the fixed frame 1 8, and use the handle 1 to vertically install the top plate 9 and the fixed frame 1 8 at the bottom into the interior of the filter body 1;

[0092] After the replacement is completed, the hydraulic rod 1 20 is controlled to extend again, so that the T-shaped pressure rod 22 is lowered and an appropriate pressing force is applied to the new filter element replacement module through the anti-slip gasket 1, or the hydraulic rod 25 is controlled to extend again, so that the U-shaped pressure rod 26 is lowered and an appropriate pressing force is applied to the new filter element replacement module through the anti-slip gasket 2.
