Description

Technical Field

[0001] The present invention relates to the technical field of battery plate curing chambers, and more particularly to a battery plate curing chamber. Background Art

[0002] In recent years, with the rapid development of the new energy industry, the requirements for the performance of lead-acid battery plates have been increasing day by day. As the core process of battery production, plate curing directly affects the capacity, life, and consistency of the battery. Currently, traditional curing chambers generally adopt static racks and unidirectional air flow designs, and have the following key defects: I. Uneven plate quality and low finished product rate due to unbalanced temperature and humidity distribution: Existing curing chambers mostly rely on single-point air supply from the top, such as fans or steam pipes, resulting in significant temperature and humidity gradients inside the chamber. It is impossible to adjust the height according to the different models of batteries, thereby reducing the temperature difference and humidity deviation, and stacking and extrusion damage: The traditional rack is a fixed grid plate, and the plates need to be stacked tightly to ensure air flow penetration. During the curing process, the lead paste expands, and the plates are squeezed against each other, causing structural deformation. At the same time, the bottom plates collapse due to the load-bearing.

[0003] II. Poor process adaptability and high energy consumption due to rigid parameter regulation: Existing equipment relies on preset temperature and humidity curves and cannot dynamically adjust according to the thickness of different battery plates, the composition of the lead paste, or the ambient temperature and humidity.

[0004] Therefore, the present invention urgently needs to provide a battery plate curing chamber. Summary of the Invention

[0015] 2. In the present invention, by providing a fifth fixing rod, pulling the fifth fixing rod outwards drives the first tooth groove to move, and the first ratchet wheel rolls along the first tooth groove. The first upper sliding block and the first lower sliding block move rightward along the curved groove, thereby pushing the first rotating plate and the second rotating plate to rotate around the first fixing bolt.

[0016] 3. In the present invention, by providing a handle, pulling the handle downwards causes the first tooth groove to rotate around the first rotating shaft and disengage from the first ratchet wheel, and the first spring pushes the layer rack to reset.

[0017] 4. The present invention is provided with a honeycomb plate, which is beneficial for better load-bearing capacity compared with traditional electrode plates during curing, avoiding micropore collapse. By pulling back the first lower base plate, the push rods on the second lower base plate and the third lower base plate, the third spring is compressed. Then, place the honeycomb plate on the first lower base plate, the second lower base plate and the third lower base plate, align the card slots with the wedge blocks. At this time, release the push rods, and the third spring rebounds, so that the wedge blocks just snap into the card slots. Pull back the push rods to release the honeycomb plate, and then the cured electrode plates can be taken out. Then, adjust the layer height to reduce the occupied space of the curing rack.

The other end of the first tooth groove 501 is fixedly connected to a handle 509. By pulling the fifth fixing rod 506, the first upper sliding block 313 and the first lower sliding block 314 can be moved in the groove. The first ratchet wheel 503 rolls on the first tooth groove 501 as the fifth fixing rod 506 moves. When the position is determined, the first ratchet wheel 503 is prevented from retracting due to the pawl on the first tooth groove 501, thus fixing the position. When the handle 509 is pulled downward, the first tooth groove 501 rotates around the first rotating shaft 502. At this time, the first ratchet wheel 503 and the first tooth groove 501 become loose and retract to the original position.

One end of the linkage rod 605 far from the wedge-shaped block 607 is fixedly connected to a third spring 606. A positioning frame 303 is fixedly connected to the surface of the honeycomb panel 601. When the push rod 604 is pulled, the linkage rod 605 will compress the third spring 606. At this time, the clamping slot 608 on the honeycomb panel 601 is aligned with the wedge-shaped block 607, and then the push rod 604 is released. The third spring 606 rebounds, and the wedge-shaped block 607 is inserted into the clamping slot 608 to fix the honeycomb panel 601 on the third lower bottom plate 306.

[0036] On both sides inside the chamber body 101, side air ducts 105 are fixedly connected.

[0037] On the top of the outer surface of the chamber body 101, an air chamber 201 is fixedly connected. On one side of the top of the air chamber 201, an air inlet 202 is fixedly connected. On the other side of the top of the air chamber 201, an air outlet 203 is fixedly connected.

[0038] The working principle of the present invention: Before feeding, the operator first pulls back the push rods 604 on the first lower base plate 301, the second lower base plate 304 and the third lower base plate 306. The third spring 606 is compressed. Then, the honeycomb plate 601 is placed on the first lower base plate 301, the second lower base plate 304 and the third lower base plate 306, making the card slot 608 align with the wedge block 607. At this time, the push rod 604 is released, and the third spring 606 rebounds, causing the wedge block 607 to just snap into the card slot 608. After that, the operator places the lead paste-coated plates layer by layer in the honeycomb plate 601 on the first lower base plate 301, the second lower base plate 304 and the third lower base plate 306. During the placement process, the second upper slider 318 and the second lower slider 317 can slide to the right through the curved slots 307 opened on the second upper base plate 305 and the second lower base plate 304. The centers of the second upper slider 318 and the second lower slider 317 rotate around the second fixing bolt 319. The other ends of the third rotating plate 315 and the fourth rotating plate 316 are respectively fixed on the second upper base plate 305 and the second lower base plate 304 and cannot move. The first upper slider 313 and the first lower slider 314 can slide to the right through the curved slots 307 opened on the first lower base plate 301 and the first upper base plate 302. The centers of the first rotating plate 308 and the second rotating plate 309 rotate around the first fixing bolt 312. The other ends of the first upper slider 313 and the first lower slider 314 are respectively fixed on the first lower base plate 301 and the first upper base plate 302 and cannot move. The first upper slider 313 and the first lower slider 314 can be moved in the slot by pulling the fifth fixing rod 506. The first ratchet wheel 503 rolls on the first tooth slot 501 as the fifth fixing rod 506 moves. When the position is determined, the first ratchet wheel 503 will be prevented from retracting due to the pawl on the first tooth slot 501, thus fixing the position. During this process, along with the movement of the fifth fixing rod 506, the first upper slider 313 and the first lower slider 314 move to the right along the slot. The first rotating plate 308 and the second rotating plate 309 rotate around the first fixing bolt 312. The included angle between the first rotating plate 308 and the second rotating plate 309 decreases, and the distance between the two ends decreases. The distance between the first upper base plate 302 and the first lower base plate 301 becomes larger. The rising height depends on the distance that the first rotating plate 308 and the second rotating plate 309 move to the right. When the handle 509 is pulled downwards, the first tooth slot 501 will rotate around the first rotating shaft 502. At this time, the first ratchet wheel 503 and the first tooth slot 501 become loose and rebound to the original position. When the first tooth slot 501 moves downwards, it will press the first spring 405. When the handle 509 is released, the first spring 405 will rebound back to the original position. The first tooth slot 501 and the first ratchet wheel 503 come into contact again. The layer rack automatically resets under the action of the first spring 405. The third rotating plate 315 and the fourth rotating plate 316 can be moved in the slot by pulling the eighth fixing rod 514. The second ratchet wheel 511 rolls on the second tooth slot 510 as the eighth fixing rod 514 moves.When the position is determined, the fourth fixing block 513 will be prevented from retracting due to the pawl on the second tooth groove 510, thus fixing the position. During this process, along with the movement of the eighth fixing rod 514, the third rotating plate 315 and the fourth rotating plate 316 move to the right along the groove. The third rotating plate 315 and the fourth rotating plate 316 rotate around the second fixing bolt 319, and the included angle between the third rotating plate 315 and the fourth rotating plate 316 decreases, and the distance between the two ends decreases, while the distance between the second lower bottom plate 304 and the second upper bottom plate 305 becomes larger. The rising height depends on the distance that the second lower sliding block 317 and the second upper sliding block 318 move to the right, so as to realize the coordinated adjustment of the distances between the three layers of bottom plates. The height of each layer can be set to different heights to adapt to different types of storage batteries, avoiding the accumulation of storage batteries. When the second tooth groove 510 is pulled downward, the second tooth groove 510 will rotate around the tenth fixing rod 517. At this time, the second ratchet wheel 511 and the second tooth groove 510 become loose and retract and restore to the original position. When the second tooth groove 510 moves downward, it will press the second spring 408. When the downward pulling of the second tooth groove 510 is released, the second tooth groove 510 will automatically rebound back to the original position under the action of the second spring 408, and the second tooth groove 510 and the second ratchet wheel 511 come into contact again. The pasted green plates are sent into the sealed chamber body 101. Under strictly controlled temperature, humidity and time conditions, the lead paste undergoes complex physical and chemical changes to complete the curing process. First of all, the curing chamber environment is maintained at a high temperature, usually 50°C to 80°C and high relative humidity, often higher than 90% in the initial stage, by steam injection, spraying or wet air circulation. This high-temperature and high-humidity environment promotes the oxidation reaction of free lead particles Pb in the lead paste with moisture and oxygen to generate lead oxide PbO and release heat. At the same time, the lead oxides PbO, Pb3O4, lead powder Pb and sulfuric acid in the lead paste react to form and stabilize basic lead sulfate crystals, mainly 3PbO·PbSO4·H2O and a small amount of 4PbO·PbSO4. During this process, water molecules are crucial as the reaction medium and the component of the crystal structure. High humidity ensures that the necessary water content is maintained inside the lead paste to support the continuous progress of the reaction and the growth of crystals. As the curing time progresses, usually 24 to 72 hours, depending on the type of plate and the process, these newly formed needle-shaped or fibrous basic lead sulfate crystals grow intertwined among the lead paste particles to form a stable network skeleton structure with high mechanical strength and porosity. In the later stage of curing, the humidity may be gradually lowered, which helps to discharge some moisture, moderately dry the lead paste and further strengthen the crystal structure, while preventing cracks caused by excessive drying. During the whole curing process, the forced air circulation system ensures the uniform distribution of temperature, humidity and gas composition, mainly the oxygen content, at each point in the curing chamber, avoiding quality differences in the plates. Finally, the cured plates have sufficient mechanical strength to withstand subsequent processing and assembly, and a developed microporous structure is formed inside, which is conducive to the penetration of the electrolyte and the charge-discharge reaction.The basic lead sulfate crystals become ideal precursors for the subsequent formation process to transform into active substances Pb and PbO2. At the same time, the free lead content is significantly reduced, the plate resistance tends to be stable, and the curing quality is monitored through the appearance of the plates, color uniformity, strength testing, and resistance measurement. The temperature and humidity control process is an air circulation: external air enters the air chamber 201 through the air inlet 202 and is conveyed to the top of the chamber body 101 by the main air duct 108. The air flow is evenly distributed through the side air duct 105 and the secondary air duct 109, penetrates the plate layer vertically downward through the air outlet 106, and the humid and hot gas is finally collected in the water tank 107 through the bottom return air duct to complete the humidification cycle. Environmental regulation: Humidification stage: Introduce high-temperature steam at 50–80°C and maintain a relative humidity >90% to promote the oxidation of free lead in the lead paste and form basic lead sulfate crystals. Drying stage: Reduce the humidity to <80% to strengthen the crystal structure and discharge moisture to prevent cracking. After curing is completed, the plates are cured at a constant temperature and humidity for 24–72 hours to form a high mechanical strength and porous structure. Pull back the push rod 604 to release the honeycomb plate 601, and then the cured plates can be taken out. Then adjust the layer height to reduce the occupied space of the curing rack.
