Abstract
Description
Technical Field
[0001] The invention relates to the technical field of electrolyzers, in particular to a high-pressure AEM water hydrogen production electrolyzer. Background Art
[0002] The high-pressure AEM water hydrogen production electrolyzer is a water electrolysis hydrogen production equipment based on anion exchange membrane technology. The AEM water electrolysis hydrogen production technology uses anion exchange membrane as the separator of the electrolytic cell to decompose water into hydrogen and oxygen. Compared with traditional alkaline water electrolysis hydrogen production technology, the AEM water electrolysis hydrogen production technology has some advantages, such as being able to operate at lower temperatures and pressures, reducing energy consumption and equipment costs; being able to use cheap catalysts to further reduce hydrogen production costs; and being highly efficient, highly controllable, and highly safe. The AEM electrolyzer is provided with a hydrogen outlet and an oxygen outlet, which are respectively used to discharge the oxygen and hydrogen produced by electrolysis.
[0003] During the electrolysis process, temperature fluctuations will affect the efficiency of the electrolysis reaction and the gas generation rate, which will lead to pressure changes. If the impurity content in the water changes, it will also affect the electrolysis reaction, resulting in pressure fluctuations, which will cause the exhaust pressure of the hydrogen outlet and the oxygen outlet to suddenly increase. The hydrogen and oxygen outlets on the AEM electrolyzer are mostly connected to the external pipeline through flanges. The flange connection method is not convenient during installation, and it cannot be accurately locked to the appropriate force when locking. If the locking force is too large, it will cause excessive extrusion on the sealing structure, which will reduce the service life of the sealing structure. If the locking force is too small, when the pressure of the exhaust gas increases, there will be leakage. Summary of the invention

DETAILED DESCRIPTION
[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0037] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. Example
[0038] Reference Figure 2-Figure 5 and Figure 11-Figure 14 , which is the first embodiment of the present invention, and this embodiment provides a high-pressure AEM water hydrogen production electrolyzer. The high-pressure AEM water hydrogen production electrolyzer includes a main body component 100, including an outlet pipe 101 and a connecting pipe 102, and the connecting pipe 102 is connected to the outlet pipe 101.
[0039] The two gas outlet pipes 101 are used to discharge hydrogen and oxygen respectively. The number of connecting pipes 102 corresponds to the gas outlet pipes 101 and is used to transport hydrogen and oxygen to designated locations.
[0040] The connecting assembly 200 is arranged on the air outlet pipe 101, and includes a rotating sleeve 201a, a connecting sleeve 201b, a fixed shaft 201c, a support frame 201d, a block 201e, a locking sleeve 201f and a sealing ring 201g. The rotating sleeve 201a is rotatably connected to the outside of the air outlet pipe 101 through a bearing, the connecting sleeve 201b is fixed to one end of the connecting pipe 102, the fixed shaft 201c is fixed in the rotating sleeve 201a, and a sliding groove 201b-1 is provided on the connecting sleeve 201b. The fixed shaft 201c slides in the slide groove 201b-1, the slide groove 201b-1 is arc-shaped, the support frame 201d is fixed to the top of the exhaust pipe 101, the block 201e is located in the support frame 201d, the rotating sleeve 201a is provided with a movable groove 201a-1, the locking sleeve 201f is located in the movable groove 201a-1, the block 201e is engaged with the locking sleeve 201f, one side of the block 201e is inclined, and the sealing ring 201g is arranged in the connecting sleeve 201b.
[0041] The number of the connecting components 200 corresponds to the two connecting pipes 102 and the air outlet pipe 101. When connecting the connecting pipe 102 to the air outlet pipe 101, the connecting sleeve 201b is sleeved on the outside of the air outlet pipe 101, and the fixed shaft 201c enters the slide groove 201b-1. At this time, the rotating sleeve 201a is rotated to make the fixed shaft 201c slide in the slide groove 201b-1. The cooperation between the two can drive the connecting sleeve 201b to move, and make the sealing ring 201g contact with the end of the air outlet pipe 101, and squeeze the sealing ring 201g through the air outlet pipe 101. When the sealing ring 201g is pressed, After the sealing ring 201g is squeezed to an appropriate force, the block 201e will engage with the locking sleeve 201f, and the two will cooperate to lock the rotating sleeve 201a, so that the rotating sleeve 201a cannot rotate in the opposite direction, and the connecting sleeve 201b cannot be separated from the air outlet pipe 101, thereby completing the connection and fixation of the connecting pipe 102 and the air outlet pipe 101, and the operation is convenient. At the same time, it can apply an appropriate squeezing force to the sealing ring 201g to avoid squeezing too tight or reducing the service life of the sealing ring 201g. Excessive force will lead to low sealing.
[0042] A baffle is fixed on one side of the locking sleeve 201f to block the block 201e. When the rotating sleeve 201a rotates too much, the block 201e will not enter the movable groove 201a-1. An arc groove is opened on the rotating sleeve 201a, and the baffle is movably connected to the arc groove.
[0043] The fastening assembly 300 is arranged at one side of the air outlet pipe 101, and includes an air inlet pipe 301a, an air outlet pipe 301b, a fixing frame 301c, an inflatable airbag 301d, a force plate 301e, a rotating disk 301f, a guide shaft 301g, a connecting plate 301h, a rotating plate 301i, a fixing rod 301j and a gear column 301k. The air inlet pipe 301a and the air outlet pipe 301b are both fixed to one side of the air outlet pipe 101 and communicated with the air outlet pipe 101. The fixing frame 301c is fixed between the air inlet pipe 301a and the air outlet pipe 301b. The inflatable airbag 301d is arranged in the fixing frame 301c. The two sides of the inflatable airbag 301d are respectively communicated with the air inlet pipe 301a and the air outlet pipe 301b. The force plate 301e is located on the fixing frame 301c. Inside, the rotating disk 301f is rotatably connected to one side of the fixed frame 301c, one end of the guide shaft 301g is fixed to the force plate 301e, the fixed frame 301c is provided with a positioning groove 301c-1, the guide shaft 301g slides in the positioning groove 301c-1, the rotating disk 301f is provided with a guide groove 301f-1, the guide shaft 301g slides in the guide groove 301f-1, the connecting plate 301h is fixed to one side of the guide shaft 301g, one side of the rotating plate 301i is fixed to the connecting plate 301h, the fixed rod 301j is fixed to one side of the rotating plate 301i, the tooth column 301k is sleeved on the outside of the fixed rod 301j, the rotating sleeve 201a is provided with a tooth groove 201a-2, and the tooth column 301k is engaged with the tooth groove 201a-2.
[0044] The air intake pipe 301a and the exhaust pipe 301b are both L-shaped. The exhaust port of the exhaust pipe 301b is smaller than the air intake port of the air intake pipe 301a. The force-bearing plates 301e are arc-shaped. There are four of them, which are evenly distributed in a ring shape in the fixed frame 301c. The force-bearing plates 301e are in contact with the expansion airbag 301d. The guide groove 301f-1 is arc-shaped. The guide shaft 301g cooperates with the positioning groove 301c-1 to position the force-bearing plates 301e to prevent the force-bearing plates 301e from shifting when moving.
[0045] When the exhaust pipe 101 starts to exhaust, part of the gas will enter the intake pipe 301a and enter the expansion airbag 301d through the intake pipe 301a. At this time, the expansion airbag 301d will expand slightly and be able to contact the force plate 301e, and the gas inside the expansion airbag 301d will enter the exhaust pipe 101 again through the exhaust pipe 301b.
[0046] When the gas pressure discharged from the exhaust pipe 101 suddenly increases, the gas pressure entering the intake pipe 301a will also increase, and the exhaust pipe 301b cannot completely discharge the gas inside the inflation airbag 301d, so that the inflation airbag 301d expands significantly and pushes the force-bearing plate 301e to move. When the force-bearing plate 301e moves, it will drive the guide shaft 301g to slide in the guide groove 301f-1, and the cooperation of the two will drive the rotating disk 301f to rotate, and the rotating disk 301f will drive the connecting rod 301e to rotate. The connecting plate 301h and the rotating plate 301i rotate, and the rotating plate 301i drives the fixing rod 301j and the tooth column 301k to rotate, and the tooth column 301k drives the rotating sleeve 201a to continue to rotate through the cooperation of the tooth groove 201a-2, so that the squeezing force on the sealing ring 201g between the connecting sleeve 201b and the air outlet pipe 101 is increased, thereby increasing the fastening force of the connection between the air outlet pipe 101 and the connecting pipe 102 and the sealing between the two, thereby avoiding gas leakage when the internal pressure of the air outlet pipe 101 increases.
[0047] When the internal pressure of the exhaust pipe 101 returns to normal, the gas pressure entering the exhaust pipe 301a and the inflation airbag 301d will decrease, so that the excess gas in the inflation airbag 301d can be slowly discharged to the outside and restored to its initial state, thereby resetting the force plate 301e and rotating the rotating disk 301f and the gear column 301k in the opposite direction, and at the same time rotating the rotating sleeve 201a to the initial angle, so as to restore the squeezing force on the sealing ring 201g and avoid applying excessive squeezing force to the sealing ring 201g for a long time, which will reduce the service life of the sealing ring 201g. Example
[0048] Reference Figure 1-Figure 14 , which is the second embodiment of the present invention, and this embodiment is based on the previous embodiment.
[0049] Specifically, a connecting block 202a is fixed to the bottom of the locking sleeve 201f, a chamber 202a-1 is opened in the connecting block 202a, a locking rod 202b is arranged in the chamber 202a-1, a first spring 202c is fixed to one side of the locking rod 202b, a locking groove 201a-3 is opened on the rotating sleeve 201a, the locking rod 202b is engaged with the locking groove 201a-3, there are multiple locking grooves 201a-3, which are evenly distributed in an arc shape on the rotating sleeve 201a, and a pull rod 202d is fixed to one side of the locking rod 202b.
[0050] The locking rod 202b cooperates with the locking groove 201a-3 to fix the connecting block 202a and the locking sleeve 201f in the current position to prevent the locking sleeve 201f from moving in the movable groove 201a-1, thereby causing the angle of the rotating sleeve 201a to be unable to be locked. The first spring 202c is used to apply a thrust to the locking rod 202b to make the locking rod 202b and the locking groove 201a-3 fit more tightly.
[0051] One end of the pull rod 202d passes through the outside of the support frame 201d and is movably connected to the support frame 201d. The pull rod 202d is used to pull the locking rod 202b to move.
[0052] By setting up multiple locking grooves 201a-3, the position of the locking sleeve 201f inside the movable groove 201a-1 can be adjusted. As the locking sleeve 201f moves in the movable groove 201a-1, the rotating sleeve 201a needs to rotate a greater angle to enable the blocking block 201e to engage with the locking sleeve 201f, thereby continuously increasing the squeezing force on the sealing ring 201g.
[0053] Since the sealing performance of the sealing ring 201g will be reduced after being squeezed by the additional force, if the sealing ring 201g is restored to the initial force, its sealing performance will be reduced. Then, the sealing performance of the sealing ring 201g can be maintained by slightly increasing the squeezing force on the sealing ring 201g.
[0054] Specifically, a push rod 203a is inserted into the bottom of the connecting block 202a, and a force groove 202b-1 corresponding to the push rod 203a is opened on the locking rod 202b, and the force groove 202b-1 is inclined. An annular groove 101-1 is opened on the air outlet pipe 101, and the bottom end of the push rod 203a is slidingly connected to the annular groove 101-1. An extrusion plate 203b is rotatably connected in the annular groove 101-1 through a rotating shaft, and the extrusion plate 203b is inclined. A groove 101-2 corresponding to the extrusion plate 203b is opened on the air outlet pipe 101, and a fourth spring 203c is fixed to one side of the connecting block 202a, and one end of the fourth spring 203c is fixed to the inner wall of the movable groove 201a-1.
[0055] One side of the extrusion plate 203b contacts the inner wall of the groove 101-2 and supports it. When the rotating sleeve 201a rotates due to the increase in pressure, it will drive the push rod 203a to slide in the annular groove 101-1 and make its bottom end contact with the extrusion plate 203b. It moves upward through the extrusion of the extrusion plate 203b, and the push rod 203a squeezes the inclined surface of the inner wall of the force groove 202b-1. The cooperation of the two can separate the locking rod 202b from the locking groove 201a-3, thereby releasing the restriction on the connecting block 202a. At this time, the fourth spring 203c is used to hold the connecting block 202a in place. The connecting block 202a applies a pulling force to move the connecting block 202a in the movable groove 201a-1. When the connecting block 202a moves a certain distance and makes the locking rod 202b coincide with the next locking groove 201a-3, the first spring 202c can be used to apply a pushing force to the locking rod 202b to make the locking rod 202b engage with the locking groove 201a-3, thereby moving the position of the locking sleeve 201f in the movable groove 201a-1. At this time, the rotating sleeve 201a needs to rotate a greater angle to enable the locking block 201e to engage with the locking sleeve 201f.
[0056] When the rotating sleeve 201a rotates in the opposite direction to the initial position, the push rod 203a will push the extrusion plate 203b to rotate into the groove 101-2. At this time, the push rod 203a will not move upward. A second torsion spring is fixed in the extrusion plate 203b. The second torsion spring is sleeved on the outside of the rotating shaft and one end is fixed to the rotating shaft. The second torsion spring is used to apply a torsional force to the extrusion plate 203b so that it can rotate to the initial angle.
[0057] Specifically, a limiting block 204 is fixed on the air outlet pipe 101, a limiting groove 201b-2 is provided in the connecting sleeve 201b, and the limiting block 204 slides in the limiting groove 201b-2.
[0058] The two cooperate to limit the connection sleeve 201b, thereby preventing the connection sleeve 201b from rotating when moving.
[0059] Specifically, a first torsion spring 205 is sleeved on the outer side of the air outlet pipe 101 , and two ends of the first torsion spring 205 are respectively fixed to the rotating sleeve 201 a and the air outlet pipe 101 .
[0060] The first torsion spring 205 applies a torsional force to the rotating sleeve 201a so that the rotating sleeve 201a can return to its initial angle after rotation.
[0061] Specifically, a second spring 206 is fixed to one side of the block 201e, and one end of the second spring 206 is fixed to the inner wall of the support frame 201d.
[0062] The second spring 206 is used to apply a thrust to the clamping block 201e so that it can be more tightly engaged with the inside of the locking sleeve 201f. Example
[0063] Reference Figure 1-Figure 14 , which is the third embodiment of the present invention, and is based on the first two embodiments.
[0064] Specifically, the fixing rod 301j is rectangular, and the fifth spring 302 is fixed to one end of the fixing rod 301j, and one end of the fifth spring 302 is fixed to the inner wall of the tooth column 301k.
[0065] When the rotating sleeve 201a is initially rotated, the tooth column 301k is first pushed to move so that the tooth column 301k is separated from the rotating sleeve 201a. When the rotating sleeve 201a is locked, the tooth column 301k can be pushed back by the fifth spring 302 so that the tooth column 301k can be engaged with the tooth groove 201a-2.
[0066] Specifically, a tightening belt 303 is sleeved on the outer side of the force-bearing plate 301e, and the tightening belt 303 is elastic.
[0067] When the inflatable airbag 301d is deflated, the tightening belt 303 can be used to apply a thrust to the four force-bearing plates 301e, so that the force-bearing plates 301e are restored to their original positions.
[0068] Specifically, a guide plate 304 is fixed to the inner wall of the air outlet pipe 101. There are two guide plates 304, which are respectively connected to the air inlet pipe 301a and the exhaust pipe 301b. The guide plates 304 are triangular in shape, and the two guide plates 304 are arranged in opposite directions.
[0069] The guide plate 304 connected to the air inlet pipe 301a is used to intercept part of the gas inside the air outlet pipe 101 so that it can enter the air inlet pipe 301a, and the guide plate 304 connected to the exhaust pipe 301b intercepts the gas in the air outlet pipe 101 to prevent it from entering the exhaust pipe 301b.
[0070] Specifically, the main component 100 also includes an electrolytic cell body 103 and a water inlet pipe 104 . The electrolytic cell body 103 is connected to an air outlet pipe 101 . There are two air outlet pipes 101 , which are located at two ends of one side of the electrolytic cell body 103 . The water inlet pipe 104 is arranged on one side of the electrolytic cell body 103 .
[0071] The water inlet pipe 104 is used to transport water into the electrolytic cell body 103 and perform electrolysis through the electrolytic cell body 103. This is a prior art and will not be elaborated in detail in this solution. Those skilled in the art can clearly understand the working principle.
[0072] In summary, the high-pressure AEM water hydrogen production electrolyzer of the present invention has the following advantages:
[0073] The air outlet pipe 101 and the connecting pipe 102 can be connected quickly and conveniently;
[0074] After the fixing is completed, a suitable squeezing force can be applied to the sealing ring 201g to prevent gas leakage and at the same time not affect its service life;
[0075] When the pressure of the gas discharged from the gas outlet pipe 101 suddenly increases, the squeezing force on the sealing ring 201g can be automatically increased to improve its sealing performance;
[0076] After the gas pressure discharged from the gas outlet pipe 101 returns to normal, the squeezing force on the sealing ring 201g can also be restored, thereby avoiding the situation where the service life of the sealing ring 201g is reduced due to long-term squeezing;
[0077] When the sealing ring 201g is subjected to an additional squeezing force causing its sealing performance to be reduced, the squeezing force will be slightly increased when the initial squeezing force is restored, so that the sealing effect of the sealing ring 201g will not be reduced.
[0078] When in use, when connecting the connecting pipe 102 to the air outlet pipe 101, the connecting sleeve 201b is sleeved on the outside of the air outlet pipe 101, and the fixed shaft 201c is inserted into the slide groove 201b-1. At this time, the rotating sleeve 201a is rotated to make the fixed shaft 201c slide in the slide groove 201b-1. The cooperation between the two can drive the connecting sleeve 201b to move, and make the sealing ring 201g contact with the end of the air outlet pipe 101, and squeeze the sealing ring 201g through the air outlet pipe 101. When the sealing ring 201g is squeezed to a suitable force, After that, the block 201e will engage with the locking sleeve 201f, and the two will cooperate to lock the rotating sleeve 201a, so that the rotating sleeve 201a cannot rotate in the opposite direction, and the connecting sleeve 201b cannot be separated from the outlet pipe 101, thereby completing the connection and fixation of the connecting pipe 102 and the outlet pipe 101, and the operation is convenient, and at the same time, it can apply a suitable extrusion force to the sealing ring 201g to avoid excessive extrusion or reducing the service life of the sealing ring 201g. Excessive force will lead to low sealing.
[0079] When the gas pressure discharged from the exhaust pipe 101 suddenly increases, the gas pressure entering the intake pipe 301a will also increase, and the exhaust pipe 301b cannot completely discharge the gas inside the inflation airbag 301d, so that the inflation airbag 301d expands significantly and pushes the force-bearing plate 301e to move. When the force-bearing plate 301e moves, it will drive the guide shaft 301g to slide in the guide groove 301f-1, and the cooperation of the two will drive the rotating disk 301f to rotate, and the rotating disk 301f will drive the connecting rod 301e to rotate. The connecting plate 301h and the rotating plate 301i rotate, and the rotating plate 301i drives the fixing rod 301j and the tooth column 301k to rotate, and the tooth column 301k drives the rotating sleeve 201a to continue to rotate through the cooperation of the tooth groove 201a-2, so that the squeezing force on the sealing ring 201g between the connecting sleeve 201b and the air outlet pipe 101 is increased, thereby increasing the fastening force of the connection between the air outlet pipe 101 and the connecting pipe 102 and the sealing between the two, thereby avoiding gas leakage when the internal pressure of the air outlet pipe 101 increases.
[0080] When the internal pressure of the exhaust pipe 101 returns to normal, the gas pressure entering the exhaust pipe 301a and the inflation airbag 301d will decrease, so that the excess gas in the inflation airbag 301d can be slowly discharged to the outside and restored to its initial state, thereby resetting the force plate 301e and rotating the rotating disk 301f and the gear column 301k in the opposite direction, and at the same time rotating the rotating sleeve 201a to the initial angle, so as to restore the squeezing force on the sealing ring 201g and avoid applying excessive squeezing force to the sealing ring 201g for a long time, which will reduce the service life of the sealing ring 201g.
[0081] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
