Description

Technical Field

[0001] This invention belongs to the field of water electrolysis hydrogen production technology, specifically a high-tank-pressure alkaline water electrolysis hydrogen production device. Background Technology

[0002] Water electrolysis is a relatively convenient method for producing hydrogen. Direct current is passed through an electrolyzer filled with electrolyte, causing water molecules to undergo an electrochemical reaction at the electrodes, decomposing into hydrogen and oxygen. It is well known that increasing the operating pressure of the water electrolysis process is one of the more economical and effective ways to improve electrolysis efficiency. Traditional water electrolysis cells typically operate at pressures between 0.1 MPa and 1.6 MPa. To improve efficiency, some in the current water electrolysis hydrogen production industry have increased the operating pressure to 3.0 MPa to 3.5 MPa, but the maximum is no more than 3.5 MPa. This places a significant challenge on the sealing performance of the electrolyzer.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) The pressure inside the box also begins to gradually increase; at this time, the pressure passes through the drying mesh plate and contacts the side moving plate, causing it to move in the limiting groove through the limiting plate. The limiting spring on the limiting rod is in a buffer state. Then, as the side moving plate moves, it drives the moving circular plate to move through the lifting rod, causing the lifting spring to be in a compressed state. Then, as the lifting spring is compressed, the lifting plate drives the linkage plate to move, causing several spring sleeve rods to slide in the spring sleeve. The spring is in a buffer state. Through the cooperation with the lifting rod, the moving circular plate moves simultaneously. Through the cooperation of the first base, the hinge rod and the second base, the two moving blocks move towards each other. The moving spring is in a buffer state, further causing the two mounting rods to drive the second sealing gasket on the bonding plate. The first sealing gasket on the mounting plate is squeezed, and the pressure generated inside the box during hydrogen production squeezes both sealing gaskets. This avoids the sealing effect that can be improved by increasing the clamping force on the seals. As described above, since the two sealing gaskets are in close contact, leakage can be avoided. At the same time, as the pressure inside the box gradually increases, the sealing performance will be better. When the pressure gradually disappears, the successive reset of the above-mentioned parts and springs will prevent the two sealing gaskets from being in a tightly pressed state. This allows them to rebound and avoids excessive compression deformation of the sealing material, thereby increasing the service life of the sealing gaskets. The mounting rod and mounting groove can prevent the mounting rod from dislodging when the pressure inside the box increases. (2) The drive block moves at the upper limit of the positioning rod, the positioning spring is in a buffer state, and then the brake box rises through the first bridge rod and the second bridge rod, so that the brake box leaves the bottom. The brake box is in the form of a filter hole, so that the impurities precipitated in the liquid inside the box, including the impurities cleaned by the full-motion cleaning mechanism, can be collected in a concentrated manner, which is convenient for the staff to clean, improves the work efficiency of the operators, and further improves the efficiency of hydrogen production. (3) The spring, which was originally in a buffer state, is reset, which in turn causes the take-up reel to rotate. This causes the rotating rack of the rotating gear to move at the upper limit of the support column through the support plate. The support spring is in a buffer state, which causes the locking rod to enter the pressure box (the end of the locking rod is already on the inner wall of the pressure box, which can prevent hydrogen leakage into the pressure box) and limit the limit plate. When the pressure inside the box reaches a certain level, the stationary contact on the limit plate will contact the moving contact on the locking rod, which will send a signal to the controller. The controller will send a signal to the alarm, which will then sound an alarm to remind the operator (a telescopic motor can be installed on the locking rod. When the two contacts come into contact, a signal will be sent to start the telescopic motor. The telescopic motor will limit the locking rod and the limit plate, limiting the limit plate to the current position to prevent it from resetting. It also facilitates the cleaning of the impurities accumulated in the brake box. This is not shown in the figure). (4) The two moving racks mesh with the moving gears and rotate, causing the drive gear on the driven shaft to rotate (one drive gear is set and the other is not set). Through the cooperation of the lifting rod, the rectangular block and the rectangular slot, the rectangular rod moves back and forth. The tension spring is constantly in the buffer reset state, which in turn causes the moving rack to mesh with the moving gear and rotate, causing the cam to rotate and reciprocate to contact the brake plate. This causes the brake plate to move back and forth on the linkage rod, and the compression spring is constantly in the buffer reset state. As the liquefied hydrogen enters the pressure box through the cooperation of the blower, it first contacts the drying screen plate. The drying screen plate can adsorb the water vapor contained therein and filter the impurities contained therein. The scraper on the bottom surface of the brake plate scrapes the drying screen plate back and forth, so that the impurities attached to its surface are cleaned, improving the purity of hydrogen production and improving the efficiency of hydrogen production. (5) When it is necessary to install the drying screen, pull the release part outward to temporarily move it away from the linkage box. Pull the connecting plate outward to put the linkage spring on the linkage rod in a buffer state, so that the two plugs on the connecting plate release the limiting setting of the linkage box. By cooperating with the linkage plug and the linkage box and pressing down, the linkage plug enters the linkage box. By releasing the connecting plate, the linkage spring resets, so that the two plugs limit the linkage plug, and the installation operation of the drying screen is completed. By releasing the lifting plate, the lifting spring on the lifting rod resets, and then the four brake plates on the lifting plate limit the plug, so as to avoid the pressure problem of the box causing the drying screen to vibrate and displace.

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0019] Implementation examples, by Figures 1 to 11 The present invention includes a tabletop 1, on which two boxes 2 are symmetrically mounted. The two boxes 2 are connected to a replenishment box 3. A conveying pipe 4 is installed on the replenishment box 3 and connected to the two boxes 2. A collection box 5 is installed on the replenishment box 3, and a transmission pipe 6 is provided on the collection box 5. The transmission pipe 6 is connected to an adaptive height-adjusting component. The adaptive height-adjusting component includes a mounting plate 7 fixedly connected to the transmission pipe 6. The mounting plate 7 is fixedly connected to the boxes 2 by bolts 8. A first sealing gasket 9 is installed on the mounting plate 7. The sealing gasket 9 is fitted and connected to the second sealing gasket 10, and the second sealing gasket 10 is fixedly connected to the bonding plate 11. A movable base 12 is symmetrically mounted on the bonding plate 11, and the movable base 12 is connected to the re-cleaning mechanism. The bonding plate 11 has symmetrically provided mounting grooves 26, and mounting rods 27 are mounted on the mounting grooves 26. Two mounting rods 27 are fixedly connected to the movable circular plate 28. A first base 29 is symmetrically mounted on the side wall of the movable circular plate 28, and a hinge rod 30 is movably mounted on the first base 29. The hinge rod 30 is fixedly mounted to a second base on the movable block 14. 31. Movable connection configuration: A plurality of spring-loaded sleeves 32 are installed on the movable circular plate 28. A spring-loaded spring 33 is fixedly installed inside each spring-loaded sleeve 32. The spring-loaded spring 33 is fixedly connected to a spring-loaded rod 34, and the spring-loaded rod 34 is slidably connected to the spring-loaded sleeve 32. A plurality of spring-loaded rods 34 are fixedly connected to a linkage plate 43. A connecting square plate 44 is installed on the linkage plate 43. A plurality of connecting square plates 44 are fixedly connected to a lifting plate 45. A lifting rod 46 is installed on the lifting plate 45, and one end of the lifting rod 46 is fixedly connected to the movable circular plate 28. The other end is fixedly connected to the side moving plate 47; a lifting spring 48 is sleeved on the lifting rod 46, one end of the lifting spring 48 is fixedly connected to the lifting plate 45, and the other end is fixedly connected to the side moving plate 47; a limit plate 49 is symmetrically installed on the side moving plate 47, and the limit plate 49 is slidably connected to the limit groove 50 provided on the pressing sleeve 23; a limit rod 51 is symmetrically installed on the limit groove 50, and a limit spring 52 is sleeved on the limit rod 51, one end of the limit spring 52 is fixedly connected to the limit groove 50, and the other end is fixedly connected to the limit plate 49; The liquid used to produce hydrogen is placed in the replenishment tank 3, and the liquid in the replenishment tank 3 is transported to the box 2 by the delivery pipe 4. Power is connected, and the cathode and anode are located inside the box 2 respectively. Since this is existing technology, it will not be described in detail here. When hydrogen is generated in the box 2, a fan (not shown in the figure) installed inside the pressure sleeve 23 transports the hydrogen into the pressure sleeve 23. Because the pressure sleeve 23 is closed and has only one outlet connected to the top surface of the box 2 via the transmission pipe 6, the hydrogen enters the collection tank 5 through the transmission pipe 6. At this time, the box... The pressure inside plate 2 gradually increases; at this time, the pressure passes through the drying mesh plate 67 and contacts the side moving plate 47, causing it to move within the limiting groove 50 via the limiting plate 49. The limiting spring 52 on the limiting rod 51 is in a buffer state. Then, as the side moving plate 47 moves, it drives the moving circular plate 28 to move via the lifting rod 46, causing the lifting spring 48 to be in a compressed state. Then, as the lifting spring 48 is compressed, the lifting plate 45 drives the linkage plate 43 to move, causing several spring sleeve rods 34 to slide within the spring sleeve 32. The spring sleeve 33 is in a compressed state. In a buffered state, the moving circular plate 28 moves simultaneously with the lifting rod 46. The first base 29, hinge rod 30, and second base 31 cause the two movable blocks 14 to move towards each other. The movable spring 15 is in a buffered state, further causing the two mounting rods 27 to drive the second sealing gasket 10 on the bonding plate 11 to press against the first sealing gasket 9 on the mounting plate 7. The pressure generated inside the casing 2 during hydrogen production presses against the two sealing gaskets, avoiding the sealing effect improved by increasing the clamping force on the seals in existing systems. As described above, the two sealing gaskets are in close contact to prevent air leakage. At the same time, the sealing performance will be better when the pressure inside the box 2 gradually increases. When the pressure gradually disappears, the successive reset of the above-mentioned parts and springs will prevent the two sealing gaskets from being in a tightly pressed state. This will allow them to rebound and prevent the compression deformation of the sealing material from increasing, thereby increasing the service life of the sealing gaskets. The installation rod 27 and the installation groove 26 can prevent the installation rod 27 from dislodging when the pressure inside the box 2 increases.

The scraper 66 is in close contact with the drying screen plate 67. The drying screen plate 67 is connected to the pressing sleeve 23 through a speed-changing component. The two movable blocks 14 move towards each other, causing the two movable racks 17 to mesh with the movable gear 18 and rotate, which in turn causes the drive gear 25 on the driven shaft 22 to rotate (one drive gear 25 is equipped with a gear, and the other is not). Through the cooperation of the toggle rod 36, the rectangular block 37, and the rectangular slot 38, the rectangular rod 39 reciprocates, and the tension spring 42 is constantly in a buffered reset state. This causes the moving rack 41 to mesh with the moving gear 53 and rotate, causing the cam 59 to rotate and reciprocate in contact with the brake plate 60, making... The brake plate 60 moves back and forth on the linkage rod 61, and the compression spring 64 is constantly in a buffer reset state. When the liquefied hydrogen enters the pressure sleeve 23 with the help of the fan, it first comes into contact with the drying screen plate 67. The drying screen plate 67 can adsorb the water vapor contained therein and filter the impurities it contains. The scraper 66 on the bottom surface of the brake plate 60 scrapes the drying screen plate 67 back and forth, so that the impurities attached to its surface are cleaned, improving the purity of hydrogen production and improving the efficiency of hydrogen production.

When the drive gear 35 rotates, it drives the drive shaft 68 to rotate the drive threaded shaft 71, causing the drive block 72 to move at the upper limit of the positioning rod 77. The positioning spring 79 is in a buffer state. Then, through the first bridging rod 73 and the second bridging rod 75, the brake box 74 rises and leaves the bottom. The brake box 74 is in the form of a filter hole, which allows the impurities deposited in the liquid inside the box 2, including the impurities cleaned by the full-motion cleaning mechanism, to be collected in a concentrated manner.

One end of the linkage rod 90 is fixedly connected to the linkage box 85, and the other end is fixedly connected to the first limiting plate 91. A linkage spring 92 is sleeved on the linkage rod 90. One end of the linkage spring 92 is connected to the first limiting plate 91. Plate 91 is fixedly connected at one end, and the other end is fixedly connected to connecting plate 89; the insert rod 88 is connected to the disengaging component; the disengaging component includes a brake clamp 105 connected to the insert rod 88, several brake clamps 105 are connected to a lifting plate 106, several lifting rods 107 are installed on the lifting plate 106, one end of the lifting rod 107 is fixedly connected to the drive box 85, and the other end is connected to the third limiting plate 108; a lifting spring 109 is sleeved on the lifting rod 107, one end of the lifting spring 109 is connected to the third limiting plate 108, and the other end is fixedly connected to the lifting plate 106; When the drying screen 67 needs to be installed, the release member is pulled outward to temporarily move it away from the drive box 85. The connecting plate 89 is pulled outward, and the drive spring 92 on the drive rod 90 is in a buffer state, so that the two insert rods 88 on the connecting plate 89 release the limiting setting on the drive box 85. The drive insert 86 and the drive box 85 cooperate and are pressed down, so that the drive insert 86 enters the drive box 85. By releasing the connecting plate 89, the drive spring 92 returns to its original position, so that the two insert rods 88 limit the drive insert 86, thus completing the installation operation of the drying screen 67. By releasing the lifting plate 106, the lifting spring 109 on the lifting rod 107 returns to its original position, so that the four brake clamps 105 on the lifting plate 106 limit the insert rods 88, so as to prevent the pressure of the box 2 from causing the drying screen 67 to vibrate and dislodge.

[0023] Please see Figure 5 and Figure 9The pressure measuring mechanism in this embodiment includes a pressure shaft 93 mounted on the take-up reel 83. One end of the pressure shaft 93 passes through the brake base 94 and is fixedly connected to the spring spring 95. The other end is connected to a rotating gear 96. The rotating gear 96 meshes with a rotating rack 97. Several support plates 98 are mounted on the rotating rack 97. The support plates 98 are slidably connected to support columns 99. One end of the support column 99 is fixedly connected to the pressure sleeve 23, and the other end is fixedly connected to the second limiting plate 100. A support spring 101 is sleeved on the support column 99. One end of the support spring 101 is fixedly connected to the second limiting plate 100, and the other end is fixedly connected to the support plate 98. A locking rod 102 is installed on the support plate 98. The locking rod 102 passes through the pressing sleeve 23 and is connected to the limiting plate 49. A stationary contact piece 103 is installed on the limiting plate 49. The stationary contact piece 103 is connected to the moving contact piece 104 provided on the locking rod 102. The contact between the two is used to control the driving stationary state of the alarm. When the positioning block 76 rises, the cooperation of the fixed seat 80, the pull rope 8, and the pulley 82 causes the spring spring 95, which was originally in a buffer state, to reset. This, in turn, causes the take-up reel 83 to reset and rotate, allowing the rotating rack 97, which is engaged with the rotating gear 96, to move at its upper limit on the support column 99 via the support plate 98. The support spring 101 remains in a buffer state, causing the locking rod 102 to enter the pressure chamber 23 (the end of the locking rod 102 is already on the inner wall of the pressure chamber 23, preventing hydrogen leakage into the pressure chamber 23) and limiting the limit plate 49. When the pressure inside the chamber 2... Once the force reaches a certain level, the stationary contact 103 on the limit plate 49 will immediately contact the moving contact 104 on the locking rod 102, causing a signal to be sent to the controller. The controller then sends a signal to the alarm, which alerts the operator. (A telescopic motor can be installed on the locking rod 102. When the two contacts come into contact, a signal is sent to start the telescopic motor, which limits the locking rod 102 and the limit plate 49, keeping the limit plate 49 in its current position to prevent it from resetting. This also facilitates the cleaning of impurities accumulated in the brake box 74, which is not shown in the figure.)
