Description

Technical Field

[0001] This invention relates to the technical field of impurity filtration, and more particularly to an activation stage water tank for AEM stack testing and its usage method. Background Technology

[0002] The activation tank for AEM (Alkaline Electrolyte Membrane) fuel cell stack testing is part of a testing apparatus specifically designed for activating AEM stacks. The tank primarily maintains the water electrolysis environment during stack testing, ensuring the stack is activated under suitable humidity conditions. During electrolysis, the degradation of catalyst particle activity is a complex and gradual phenomenon. It not only directly affects electrolysis efficiency but also involves a series of chain reactions, profoundly impacting the performance and economy of the entire electrolysis system. While promoting chemical reactions, the active sites on the catalyst particles suffer wear and poisoning. Therefore, the water entering the activation tank must be filtered to remove the catalyst (in its highly dispersed, muddy solid form).

[0003] Existing technologies typically use external filters, which usually require additional piping connections. This can make the installation process more complicated and take up more external space. At the same time, it requires more power to push the water flow through the external pipes and filtration device, so the power consumption is usually higher than that of built-in filters. When filtration is performed inside the activation tank, the flow of electrolyzed water is often slowed down due to the clogging of the filter holes, which can affect the fluctuation of the liquid level.

[0004] Based on the above, this invention proposes an activation platform water tank for AEM fuel cell stack testing and its usage method. Summary of the Invention

[0005] In order to overcome the technical shortcomings in the background art, the present invention provides an activation stage water tank for AEM stack testing and a method of using it.

[0006] An activation stage water tank for AEM fuel cell stack testing includes a tank body. One side of the tank body has symmetrically distributed water inlets. The tank body also has multiple water outlets. A discharge pipe for discharging catalyst is connected to the side of the tank body near the water inlets. A cover plate is placed on top of the tank body. An L-shaped baffle is fixedly connected inside the tank body. A water inlet frame is fixedly connected to the side of the tank body near the water inlets. Electrolyzed water flows into the water inlet frame through the water inlets. The interior of the water inlet frame is hollow. The upper side of the water inlet frame has symmetrically distributed inclined grooves, and the lower side of the water inlet frame has symmetrically distributed horizontal grooves. A water guide frame is movably connected to the water inlet frame, and the water guide frame is inclined downwards. The inclined grooves and horizontal grooves of the water inlet frame are respectively... The upper and lower sides of the water guide frame are limited. The side of the water inlet frame near the horizontal groove is horizontally slidably connected to a first magnetic block symmetrically distributed along the water guide frame. The first magnetic block is rotatably connected to the water guide frame. The side of the water inlet frame near the first magnetic block is fixedly connected to an electromagnet symmetrically distributed along the water inlet frame. When energized, the electromagnet attracts adjacent first magnetic blocks through magnetic attraction. The water inlet frame is vertically slidably connected to a sliding plate, which contacts the water guide frame. The L-shaped baffle is fixedly connected to two fixed baffles. Both the L-shaped baffle and the fixed baffles have rectangular through holes distributed at equal intervals. A filter plate is inserted between the two fixed baffles. The fixed baffle near the water guide frame is fixedly connected to a partition plate.

[0007] Optionally, the top of the discharge pipe has circumferentially distributed fan-shaped through holes, and the bottom of the discharge pipe is open.

[0008] Optionally, it also includes an elastic telescopic plate, which is rotatably connected to the partition plate. A guide cone is provided on the side of the water guide frame near the elastic telescopic plate. A first torsion spring symmetrically distributed along the elastic telescopic plate is fixedly connected between the partition plate and the elastic telescopic plate. A fixing rod symmetrically distributed along the water guide frame is fixedly connected on the side of the water guide frame near the elastic telescopic plate. The fixing rod is in a pressing fit with the elastic telescopic plate.

[0009] Optionally, the guide cone is configured to be higher in the middle and lower on both sides.

[0010] Optionally, it also includes an inner baffle, which is slidably connected to the side of the housing near the L-shaped baffle. The inner baffle is slidably connected to the L-shaped baffle and is used to block the rectangular through hole of the L-shaped baffle. The inner baffle is horizontally slidably connected to an outer baffle that is symmetrically distributed along the inner baffle. The outer baffle is slidably connected to the fixed baffle near the partition plate and is used to block the rectangular through hole of the fixed baffle near the partition plate. The partition plate separates the symmetrically distributed outer baffles. A tension spring is fixedly connected between the inner baffle and the outer baffle. At least one second magnetic block is fixedly connected to both the housing and the inner baffle, and adjacent second magnetic blocks are magnetically attracted to each other.

[0011] Optionally, it also includes a locking block, which is slidably connected to the side of the housing near the inner baffle. The locking block is used to limit the position of the filter plate, and a spring symmetrically distributed along the locking block is fixedly connected between the locking block and the housing.

[0012] Optionally, one side of the locking block is provided as an inclined surface, and the locking block is pressed and engaged with the inner baffle through the inclined surface.

[0013] Optionally, it also includes a pusher, which is slidably connected to the partition plate and movably connected to the adjacent fixed rod, with the outer baffle close to the pusher in a pressing fit with the pusher.

[0014] Optionally, it also includes a rotating frame, which is rotatably connected to the lower part of the discharge pipe. The rotating frame passes through the discharge pipe and has circumferentially distributed fan-shaped through holes. A connecting pipe is rotatably connected to the bottom of the rotating frame, and the connecting pipe has circumferentially distributed fan-shaped through holes. A second torsion spring is fixedly connected between the rotating frame and the inner top wall of the discharge pipe.

[0015] Optionally, a method for using an activation platform water tank for AEM fuel cell stack testing includes the following steps:

[0016] S1: Block the water outlet of the tank and the discharge pipe;

[0017] S2: Electrolyzed water flows into the water inlet frame through the water inlet of the tank, and is sprayed out through the side of the water inlet frame near the filter plate;

[0018] S3: Control the electromagnet to alternately turn on and off power at regular intervals;

[0019] S4: Open the discharge pipe to discharge the precipitated catalyst.

[0020] The beneficial effects are: the invention uses the upper and lower halves of the filter plate alternately for filtration, which allows each half of the filter plate to "rest" at intervals, effectively extending the overall service life of the filtration system and reducing the frequency of maintenance.

[0021] When one side of the filter plate is blocked, this invention can avoid local high pressure on the filter plate caused by blockage by alternating the use of the other side of the filter plate, compared with continuous filtration, thereby reducing interference with the stability of the electrolyzed water flow and maintaining a stable water flow.

[0022] During the filter plate's "rest" period, the present invention can also use the electrolytic water pressure behind the L-shaped baffle to flush away the catalyst blocking the filter holes, automatically solving the problem of filter plate clogging and improving the overall filtration efficiency.

[0023] This invention utilizes an elastic telescopic plate to scrape off the filtered catalyst and guide it to the top of the water guide frame. Under the action of the guide cone, the catalyst falls down along both sides to the lower front of the box, preventing the catalyst portion filtered on the upper half of the filter plate from remaining on the partition plate.

[0024] This invention blocks the rectangular holes of the two fixed grids at the front and rear by simultaneously pulling the inner and outer baffles, thereby isolating the filter plate in the middle and making it easy to remove the filter plate to the right for cleaning or replacement.

[0025] When the inner baffle is pushed to the left, the inner baffle presses the locking block to slide downward, thereby limiting and fixing the filter plate and preventing the filter plate from sliding freely left and right during filtration, which would affect the filtration process.

[0026] This invention utilizes a water guide frame that works in conjunction with a fixed rod and a pusher frame, allowing the outer baffles on the upper and lower sides to alternately scrape off the catalyst adhering to the filter plate, thereby cleaning the filter plate in a timely manner and reducing clogging.

[0027] This invention changes the state of the connecting pipe and the discharge pipe by rotating the rotating frame, so that the catalyst can be discharged in small amounts and multiple times in a timely manner during the filtration process without stopping the filtration to discharge the catalyst. This is very convenient and efficient. Moreover, when the filtration is completed, the catalyst in the discharge pipe can be discharged quickly all at once. Attached Figure Description

Detailed Implementation

[0041] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0042] Example 1: An activation platform water tank for AEM stack testing, combined with attached... Figure 1 To be continued Figure 4 The system includes a housing 1, with symmetrically distributed water inlets on the front side of the housing 1, and multiple randomly distributed water outlets on the left, right, rear, and bottom sides of the housing 1. A discharge pipe 101 for discharging catalyst is connected to the bottom front side of the housing 1. A cover plate 2 is placed on the top of the housing 1. An L-shaped baffle 3 is fixedly connected to the front side inside the housing 1. A water inlet frame 4 is fixedly connected to the side of the housing 1 near the water inlets, located in front of the L-shaped baffle 3. Electrolyzed water flows into the water inlet frame 4 through the water inlets. The inside of the water inlet frame 4 is hollow. A symmetrically distributed inclined groove is opened on the upper side of the water inlet frame 4, and a symmetrically distributed horizontal groove is opened on the lower side of the water inlet frame 4. A water guide frame 5 is movably connected to the water inlet frame 4, tilting downwards. The inclined grooves and horizontal grooves of the water inlet frame 4 limit the upper and lower sides of the water guide frame 5, respectively. A first magnetic block 6 is slidably connected to the side of the water frame 4 near the horizontal tank, which is symmetrically distributed along the left and right sides of the water guide frame 5. The first magnetic block 6 is rotatably connected to the water guide frame 5. An electromagnet 7 is fixedly connected to the side of the water inlet frame 4 near the first magnetic block 6, which is symmetrically distributed along the left and right sides of the water inlet frame 4. When energized, the electromagnet 7 attracts the adjacent first magnetic block 6 through the magnetic force of attraction. A sliding plate 8 is slidably connected to the upper part of the water inlet frame 4 in the vertical direction. The sliding plate 8 contacts the top of the water guide frame 5. Two fixed baffles 10 are fixedly connected to the inner top of the L-shaped baffle 3. Both the L-shaped baffle 3 and the fixed baffles 10 have rectangular through holes that are evenly distributed from left to right. A filter plate 9 is inserted between the two fixed baffles 10. The rear side of the water inlet frame 4 faces the filter plate 9. The electrolyzed water sprayed through the water inlet frame 4 falls onto the filter plate 9. A partition plate 11 is fixedly connected in the middle of the fixed baffles 10 near the water guide frame 5.

[0043] First, block all the outlets and discharge pipes 101 of the tank 1. Then, let the electrolyzed water flow into the inlet frame 4 through the inlet of the tank 1 and spray it out through the rear side of the inlet frame 4. Let it pass through the rectangular through hole of the front fixed baffle 10, the filter plate 9, the rectangular through hole of the rear fixed baffle 10, and the rectangular through hole of the L-shaped baffle 3 into the rear side of the tank 1. The filter plate 9 isolates the electrolyzed catalyst inside the front side of the tank 1, preventing the electrolyzed catalyst from flowing back into the activation tank 1. Without affecting the subsequent electrolysis efficiency, it does not require additional pipes and external space, reducing leakage points and maintenance complexity, making the system more stable and reliable. Compared with an external filter, it requires less power to drive water circulation, so its energy consumption is lower.

[0044] During the filtration process described above, the electromagnet 7 is alternately switched on and off at regular intervals. When the electromagnet 7 is energized, it moves backward under magnetic attraction until it is attracted to the adjacent first magnetic block 6. The electromagnet 7 drives the water guide frame 5 to move backward along the horizontal groove of the water inlet frame 4. At the same time, guided by the inclined groove of the water inlet frame 4, the water guide frame 5 moves backward and swings upward around the first magnetic block 6, so that the water inlet frame 4 faces the upper part of the partition plate 11. Thus, after the electrolyzed water is sprayed out from the water inlet frame 4, it will be filtered from the upper part of the filter plate 9. When the electromagnet 7 is de-energized, the water guide frame 5 swings downward under gravity, and then moves forward to reset under the guidance of the inclined groove of the water inlet frame 4. When the water guide frame 5 moves forward, it drives the electromagnet 7 to move forward to reset. Thus, after the electrolyzed water is sprayed out from the water inlet frame 4, it will be filtered from the lower part of the filter plate 9. The partition plate 11 isolates the working states of the upper and lower parts of the filter plate 9.

[0045] During the up-and-down swinging process of the water guide frame 5, the slide plate 8 adapts to the up-and-down sliding, so that the slide plate 8 always contacts the top of the water guide frame 5, thereby blocking the gap formed between the water guide frame 5 and the top of the water inlet frame 4 when swinging, and preventing electrolyzed water from leaking through the gap.

[0046] After filtration is completed, a small amount of electrolyzed water will back-seep into the front of the tank 1. Therefore, before opening the discharge pipe 101, the catalyst should be allowed to settle in the tank 1 for a period of time. Then, the discharge pipe 101 should be opened to discharge the settled catalyst. If it is found that the sediment is no longer discharged but water is being drained, the discharge pipe 101 should be closed immediately.

[0047] In summary, the present invention uses the upper and lower halves of the filter plate 9 alternately for filtration, allowing each half of the filter plate 9 to "rest" at intervals, effectively extending the overall service life of the filtration system and reducing the frequency of maintenance.

[0048] Moreover, when one side of the filter plate 9 is blocked, the other side of the filter plate 9 can be used alternately. Compared with continuous filtration, this can avoid local high pressure on the filter plate 9 caused by blockage, thereby reducing interference with the stability of the electrolyzed water flow and maintaining a stable water flow.

[0049] In addition, during the "rest" period of filter plate 9, the electrolytic water pressure behind the L-shaped baffle 3 can be used to flush away the catalyst blocking the filter holes, automatically solving the problem of filter hole blockage of filter plate 9 and improving the overall filtration efficiency.

[0050] Example 2: Based on Example 1, combined with Appendix Figure 5It also includes an elastic telescopic plate 12, which is rotatably connected to the partition plate 11. A guide cone 121 is provided on the top of the water guide frame 5 near the side of the elastic telescopic plate 12. The guide cone 121 is designed to be high in the middle and low on both sides, which is used to guide the catalyst falling on the top of the water guide frame 5 downward along the left and right sides. A first torsion spring 13 is fixedly connected between the partition plate 11 and the elastic telescopic plate 12 and is symmetrically distributed on the left and right sides of the elastic telescopic plate 12. A fixing rod 14 is fixedly connected to the rear of the water guide frame 5 and is symmetrically distributed on the left and right sides of the water guide frame 5. The fixing rod 14 is pressed and engaged with the elastic telescopic plate 12.

[0051] When the water guide frame 5 swings upward, the water guide frame 5 drives the fixed rod 14 to gradually detach from the elastic telescopic plate 12. The first torsion spring 13, which is in a stored state, resets and drives the elastic telescopic plate 12 to swing clockwise to a horizontal state. The elastic telescopic plate 12 shortens, and the catalyst filtered by the upper part of the filter plate 9 falls onto the elastic telescopic plate 12.

[0052] When the water guide frame 5 swings downward, the water guide frame 5 squeezes the elastic telescopic plate 12 counterclockwise to the tilted state through the fixed rod 14. The elastic telescopic plate 12 extends and the first torsion spring 13 deforms. At this time, the elastic telescopic plate 12 scrapes off the catalyst filtered by the filter plate 9 and tilts it to the top of the water guide frame 5. Under the action of the guide cone 121, the catalyst falls down along the left and right sides to the lower front of the box 1, preventing the catalyst part filtered by the upper half of the filter plate 9 from remaining on the partition plate 11.

[0053] Example 3: Based on Example 2, combined with Appendix Figure 6 To be continued Figure 8 It also includes an inner baffle 15, which is slidably connected to the side of the housing 1 near the L-shaped baffle 3. Two arc-shaped handles are fixedly connected to the right side of the inner baffle 15 to facilitate pushing and pulling the inner baffle 15 left and right. The inner baffle 15 is slidably connected to the L-shaped baffle 3 and is used to block the rectangular through hole of the L-shaped baffle 3. The inner baffle 15 is slidably connected to an outer baffle 16 that is symmetrically distributed along the inner baffle 15 in the left and right direction. The outer baffle 16 is slidably connected to the fixed baffle 10 on the front side and is used to block the rectangular through hole of the fixed baffle 10 on the front side. The partition plate 11 separates the symmetrically distributed outer baffles 16. A tension spring 17 is fixedly connected between the inner baffle 15 and the outer baffle 16. Two second magnetic blocks 18 are fixedly connected to the front and rear of the housing 1 and the inner baffle 15. The adjacent second magnetic blocks 18 are magnetically attracted to each other.

[0054] When the filter plate 9 needs to be cleaned or replaced, pull the inner baffle 15 and the outer baffle 16 to the right at the same time. The adjacent second magnetic blocks 18 will disengage from each other, so that the rectangular holes of the two fixed baffles 10 at the front and rear are blocked, thus isolating the filter plate 9 in the middle. At this time, the filter plate 9 can be taken away to the right for cleaning or replacement.

[0055] After cleaning or replacement, push the baffle and outer baffle 16 to the left simultaneously, so that the rectangular holes of the two fixed baffles 10 are opened, and the adjacent second magnetic blocks 18 come into contact with each other, fixing the inner baffle 15 and preventing the inner baffle 15 from sliding left and right at will during filtration, which would cause the outer baffle 16 to move left and right at will and affect the filtration work. When pushing and pulling the inner baffle 15 and the outer baffle 16, the tension spring 17 is always in the natural state.

[0056] Combined with appendix Figure 9 It also includes a locking block 19, which is slidably connected to the right side of the housing 1. The right side of the locking block 19 is set as an inclined surface. The locking block 19 is pressed and engaged with the inner baffle 15 through the inclined surface. The locking block 19 is used to limit the filter plate 9. A spring 20 is fixedly connected between the locking block 19 and the housing 1, which is symmetrically distributed along the front and back of the locking block 19.

[0057] When the inner baffle 15 is pulled to the right, the inner baffle 15 disengages from the locking block 19. The spring 20, which is in a compressed state, returns to its original position and causes the locking block 19 to slide upward. At this time, the locking block 19 no longer blocks the filter plate 9, and the filter plate 9 can be removed to the right for cleaning or replacement. When the inner baffle 15 is pushed to the left, the inner baffle 15 presses the locking block 19 downward and slides downward. The spring 20 is compressed, so that the filter plate 9 is limited and fixed, preventing the filter plate 9 from sliding left and right at will during filtration and affecting the filtration work.

[0058] Combined with appendix Figure 10 It also includes a pusher 21, which is slidably connected to the left side of the partition plate 11, and is movably connected to the left side of the fixed rod 14. The left side of the outer baffle 16 is pressed against the pusher 21.

[0059] When the water guide frame 5 swings downward, the water guide frame 5 drives the push frame 21 to slide downward through the fixed rod 14. At this time, the upper side of the push frame 21 presses against the upper outer baffle 16, causing the upper outer baffle 16 embedded in the front fixed baffle 10 to slide to the right relative to the filter plate 9. The upper tension spring 17 is stretched, so the upper outer baffle 16 scrapes off the catalyst attached to the upper half of the filter plate 9. At the same time, the lower side of the push frame 21 separates from the lower outer baffle 16, and the lower tension spring 17, which is in a stretched state, resets and drives the lower outer baffle 16 to slide to the left and embed into the front fixed baffle 10.

[0060] When the water guide frame 5 swings upward, the water guide frame 5 drives the push frame 21 to slide upward through the fixed rod 14. At this time, the lower side of the push frame 21 presses against the lower outer baffle 16, causing the lower outer baffle 16 embedded in the front fixed baffle 10 to slide to the right relative to the filter plate 9. The lower tension spring 17 is stretched, so the lower outer baffle 16 scrapes off the catalyst attached to the lower half of the filter plate 9. At the same time, the upper side of the push frame 21 separates from the upper outer baffle 16, and the upper tension spring 17, which is in a stretched state, resets and drives the upper outer baffle 16 to slide to the left and embed into the front fixed baffle 10.

[0061] This alternating process helps to clean the filter plate 9 in a timely manner, reducing the likelihood of clogging.

[0062] Example 4: Based on Example 3, combined with Appendix Figure 11 and attached Figure 12 It also includes a rotating frame 22, which is rotatably connected to the lower part of the discharge pipe 101. The bottom of the rotating frame 22 has three circumferentially distributed fan-shaped through holes, and the top of the discharge pipe 101 has three circumferentially distributed fan-shaped through holes. The bottom of the discharge pipe 101 is open. The rotating frame 22 is inserted into the discharge pipe 101. The bottom of the rotating frame 22 is rotatably connected to a connecting pipe 23. The top of the connecting pipe 23 has three circumferentially distributed fan-shaped through holes. A second torsion spring 24 is fixedly connected between the rotating frame 22 and the inner top wall of the discharge pipe 101.

[0063] The filtered catalyst will settle at the bottom of the housing 1 and eventually flow into the discharge pipe 101 through the fan-shaped through hole. At this time, the bottom of the discharge pipe 101 is in a closed state due to the misalignment of the connecting pipe 23 and the rotating frame 22.

[0064] If too much catalyst accumulates in the chamber 1 during filtration, the rotating frame 22 is rotated at a set angle, so that the top of the discharge pipe 101 is closed due to the misalignment of the discharge pipe 101 and the rotating frame 22, while the bottom of the discharge pipe 101 is open due to the alignment of the connecting pipe 23 and the rotating frame 22. In this way, the catalyst in the discharge pipe 101 is discharged through the connecting pipe 23. Then the rotating frame 22 is rotated in the opposite direction to reset, so that the catalyst in the chamber 1 flows back into the discharge pipe 101. This process is repeated, so that the catalyst can be discharged in small amounts and multiple times during filtration without stopping the filtration process, which is very convenient.

[0065] If the catalyst only needs to be discharged when filtration is completed, the rotating frame 22 is controlled to rotate at a set angle so that the top of the discharge pipe 101 is in an open state under the alignment of the discharge pipe 101 and the rotating frame 22, and the bottom of the discharge pipe 101 is also in an open state under the alignment of the connecting pipe 23 and the rotating frame 22. In this way, the catalyst in the discharge pipe 101 can be discharged quickly in one go.

[0066] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.

(10) Sliding connection, the outer baffle (16) is used to block the rectangular through hole of the fixed baffle (10) near the side of the partition plate (11), the partition plate (11) separates the symmetrically distributed outer baffles (16), the inner baffle (15) is fixedly connected to the outer baffle (16) by a tension spring (17), and at least one second magnetic block (18) is fixedly connected to both the housing (1) and the inner baffle (15), and adjacent second magnetic blocks (18) are magnetically attracted to each other; It also includes a pusher (21), which is slidably connected to the partition plate (11), and the pusher (21) is movably connected to the adjacent fixed rod (14). The outer baffle (16) is pressed against the pusher (21) on the side close to the pusher (21). When the electromagnet (7) is energized, it moves backward under the magnetic attraction until it is attracted to the adjacent first magnetic block (6). The electromagnet (7) drives the water guide frame (5) to move backward along the horizontal groove of the water inlet frame (4). At the same time, guided by the inclined groove of the water inlet frame (4), the water guide frame (5) moves backward and swings upward around the first magnetic block (6), so that the water inlet frame (4) faces the top of the partition plate (11). In this way, electrolyzed water is sprayed out from the water inlet frame (4). Afterwards, the water will be filtered from the upper part of the filter plate (9). When the electromagnet (7) is de-energized, the water guide frame (5) swings downward under the action of gravity, and thus moves forward to reset under the guidance of the inclined groove of the water inlet frame (4). When the water guide frame (5) moves forward, it drives the electromagnet (7) to move forward to reset. In this way, after the electrolyzed water is sprayed out from the water inlet frame (4), it will be filtered from the lower part of the filter plate (9). The partition plate (11) isolates the working state of the upper and lower parts of the filter plate (9).
