Abstract
Description
Technical Field
[0001] This utility model relates to the field of annealing basket technology, specifically to a large-pore basket for annealing hydrogen storage alloys. Background Technology
[0002] Hydrogen storage alloys are a class of intermetallic compounds that can reversibly absorb and release hydrogen. They play a key role in the field of hydrogen energy storage and utilization. During the preparation process, hydrogen storage alloys need to be placed in an annealing basket and annealed in an annealing furnace. This is to improve the microstructure and properties of the alloy by precisely controlling the temperature and holding time, so that it can meet the requirements of hydrogen storage.
[0003] In existing technologies, the structure of hydrogen storage annealing baskets is mostly made of a solid steel plate base with a stainless steel basket surrounded by small holes. This structure results in slow heating of the alloy in the middle and lower parts of the annealing basket during alloy heat treatment annealing, leading to a short effective annealing time. The degree of elimination of defects in the alloy crystal structure and the homogenization of micro-composition are inconsistent, affecting the electrochemical performance of the hydrogen storage alloy. At the same time, the heat dissipation area is small when the alloy is cooled after annealing, and the temperature of the alloy in the center of the basket cannot drop at the same time as other parts. The temperature of the alloy in the center is 30-40°C higher than that of the surrounding alloy. After being taken out of the furnace, the alloy is prone to oxidation, resulting in a decrease in the electrochemical performance of the alloy. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] For examples, please refer to Figures 1 to 7 A large-pore basket for annealing hydrogen storage alloys includes a frame 1 with a feed inlet 2. A baffle 4 is rotatably mounted at the feed inlet 2 via a first rotating shaft 3. The first rotating shaft 3 is embedded in the side wall of the frame 1 and is rotatably connected to the frame 1. One end of the baffle 4 is fixedly connected to the first rotating shaft 3. An arc-shaped groove 28 is formed on the inner bottom wall of the feed inlet 2, which matches the movement trajectory of the baffle 4. Figure 7 As shown, it also includes a steel mesh 5, a ventilation slot 6, a material frame 7, a material carrier plate 8, and a drive mechanism. A steel mesh 5 is fixedly connected to the inner wall of the frame 1. The steel mesh 5 is a high-density steel mesh with small holes to avoid the risk of small hydrogen storage alloy blocks falling out and causing short circuit damage to the heating belt. Multiple ventilation slots 6 are opened on the outer wall of the frame 1. The material frame 7 is set inside the frame 1 and slides in cooperation with the inner wall of the steel mesh 5.
[0029] like Figure 1 , Figure 5 and Figure 6As shown, the material carrier plate 8 is located on the lower side of the material frame 7 and slides against the inner wall of the steel mesh 5 through a limiting component. The material carrier plate 8 and the material frame 7 are fixedly connected by multiple connecting plates 21. Ventilation holes 27 are provided on the bottom and side walls of the material frame 7 and on the material carrier plate 8. The limiting component includes multiple limiting plates 9 and two limiting rods 11. Multiple limiting plates 9 are fixedly connected to the material carrier plate 8. Multiple sliding grooves 10 that cooperate with the limiting plates 9 are provided on the frame 1. The height of the sliding grooves 10 is greater than the height of the connecting plates 21. The two ends of the two limiting rods 11 are fixedly connected to the inner top wall and inner bottom wall of the two sliding grooves 10 at one end of the frame 1, respectively. Both the limiting rods 11 and the limiting plates 9 corresponding to the limiting rods 11 are provided with ventilation holes 27. Locking hole 25, with locking pin 26 slidably disposed inside. By driving the material carrier plate 8 to move upward along the inner side wall of the steel mesh 5, the connecting plate 21 and the material frame 7 are moved upward. When the bottom end of the material frame 7 is above the top end of the frame 1, the locking hole 25 corresponds to the locking pin 26. By inserting the locking pin 26 into the locking hole 25, one end of the material carrier plate 8 is horizontally fixed. Then, hydrogen storage alloy can be placed on the material frame 7 and the material carrier plate 8. After that, the material carrier plate 8 is driven back to the initial position, and the frame 1 is transferred to the annealing furnace for annealing. By layering the alloy, the alloy is prevented from accumulating in the frame 1, so that the alloy in the core heats up and cools down more slowly.
[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the drive mechanism is located at one end of the frame 1, and is used to simultaneously drive the lifting and lowering of the material carrier plate 8 and the rotation of the baffle 4. The drive mechanism includes two racks 12, two fixed plates 13, a second rotating shaft 14, two first gears 15, a support plate 16, a connecting shaft 17, a second gear 18, a large gear 19, and a rotating rod 20. One end of each of the two racks 12 is fixedly connected to two limiting plates 9 on one end of the frame 1. One end of each of the two fixed plates 13 is fixedly connected to one end of the frame 1. Both ends of the second rotating shaft 14 are rotatably connected to the two fixed plates 13. The two first gears 15 are both mounted on the second rotating shaft 14 and fixed to the second rotating shaft 14. The frame 1 is fixedly connected, with two first gears 15 meshing with two racks 12 respectively. One end of the support plate 16 is fixedly connected to one end of the frame 1. One end of the connecting shaft 17 passes through the fixed plate 13 and is coaxially fixedly connected to one end of the second rotating shaft 14. The other end passes through the support plate 16 and is rotatably connected to the support plate 16. The second gear 18 is fitted onto the connecting shaft 17 and is coaxially fixedly connected to the connecting shaft 17. The large gear 19 is located inside the side wall of the frame 1. The large gear 19 is fitted onto the first rotating shaft 3 and is coaxially fixedly connected to the first rotating shaft 3. The large gear 19 meshes with the second gear 18. One end of the rotating rod 20 is fixedly connected to the other end of the connecting shaft 17. Figure 4As shown, the other end of the rotating rod 20 has a through hole, and a push rod 22 is slidably connected in the through hole. The side wall of the frame 1 has a positioning hole 23 that matches one end of the push rod 22. A retaining ring 24 is fitted on the push rod 22. The retaining ring 24 can prevent the push rod 22 from moving out of the rotating rod 20. By pulling the push rod 22, one end of the push rod 22 is moved out of the positioning hole 23.
[0031] Then, rotating push rod 22 drives rotating rod 20 to rotate around the axis of connecting shaft 17. Rotating rod 20 drives connecting shaft 17 to rotate, and connecting shaft 17 simultaneously drives second gear 18 and second rotating shaft 14 to rotate. Second gear 18 drives large gear 19 to rotate, and large gear 19 drives first rotating shaft 3 to rotate. First rotating shaft 3 drives baffle 4 to rotate around the axis of first rotating shaft 3 along the inner wall of arc groove 28. Meanwhile, the rotation of second rotating shaft 14 drives two first gears 15 to rotate. Gear 15 drives two racks 12 to move upward, rack 12 drives corresponding limiting plate 9 to move upward, limiting plate 9 drives material plate 8 to move upward. When limiting plate 9 moves to the top of slide groove 10, the locking hole 25 on the limiting plate 9 and limiting rod 11 at the other end of frame 1 corresponds to the limiting plate 9 and limiting rod 11, and push rod 22 corresponds to positioning hole 23. By inserting locking pin 26 into locking hole 25, one end of push rod 22 is inserted into positioning hole 23, thus fixing material plate 8.
[0032] Working principle: This large-pore basket for annealing hydrogen storage alloys, when loading the hydrogen storage alloy, moves one end of the push rod 22 out of the positioning hole 23 by pulling it. Then, rotating the push rod 22 drives the rotating rod 20 to rotate around the axis of the connecting shaft 17. The rotating rod 20 drives the connecting shaft 17 to rotate, which in turn drives the second gear 18 and the second rotating shaft 14 to rotate. The second gear 18 drives the large gear 19 to rotate, which in turn drives the first rotating shaft 3 to rotate. The first rotating shaft 3 drives the baffle 4 to rotate around the axis of the first rotating shaft 3 along the inner wall of the arc-shaped groove 28. Meanwhile, the rotation of the second rotating shaft 14 drives the two first gears 15 to rotate. The two first gears 15 drive the two racks 12 to move upward respectively. The racks 12 drive the corresponding limiting plates 9 to move upward. The limiting plates 9 drive the material plate 8 to move upward. When the limiting plates 9 move to the top of the slide 10, the locking holes 25 on the limiting plates 9 and limiting rods 11 at the other end of the frame 1 correspond to each other, and the push rod 22 corresponds to the positioning hole 23. By inserting the locking pin 26 into the locking hole 25, one end of the push rod 22 is inserted into the positioning hole 23, thus fixing the material plate 8. At this time, the bottom of the material frame 7 is above the top of the frame 1, the material plate 8 is inside the frame 1 and is in contact with the steel mesh 5, and the feed port 2 is "open".
[0033] Then, place the hydrogen storage alloy at the bottom of the frame 1, on the carrier plate 8, and in the material frame 7 respectively. The stacked material should not be too high, so that there is a gap between the top of the material stacked at the bottom of the frame 1 and the bottom of the carrier plate 8, and a gap between the top of the material stacked on the carrier plate 8 and the bottom of the material frame 7. When discharging, slowly pour in the hydrogen storage alloy to avoid generating too much dust.
[0034] Finally, move one end of the locking pin 26 and the push rod 22 out of the locking hole 25 and the positioning hole 23 respectively. Hold the push rod 22 and keep the rotating rod 20 rotating as slowly as possible to slowly return the material plate 8 to the initial position. After the inner bottom wall of the slide 10 supports multiple limit plates 9, transfer the frame 1 into the annealing furnace. By setting vent holes and ventilation holes 27 and stacking hydrogen storage alloy in layers, the hydrogen storage alloy can be heated more evenly, avoiding the accumulation of material in the frame 1, which would cause the core to heat up and cool down more slowly.
[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
