Description

Technical Field

[0001] This utility model relates to the field of electrode plate curing and drying rack technology, specifically a multi-layer flip-plate structure for electrode plate curing and drying rack. Background Technology

[0002] In the manufacturing process of lead-acid battery plates, plate curing and drying is a crucial and important step. Because the lead paste particles coated on the green plates are relatively loose and not firmly connected, the curing chamber needs to maintain certain temperature, humidity, and oxygen conditions to allow the grid to oxidize and form an corrosion layer that firmly bonds with the active material of the lead paste. This results in a continuous and strong colloidal network skeleton structure among the active materials of the lead paste, while simultaneously oxidizing the free lead in the lead paste, enhancing its hardness and mechanical strength. During this process, the placement of the green plates in the curing chamber affects the physical and chemical reactions that occur in the active material of the lead paste, thus restricting the plate curing and drying effect. Therefore, the structure of the curing chamber has a critical impact on the performance of the produced battery.

[0003] However, the existing flap structure may lead to complex airflow organization in the drying chamber, making it difficult to ensure uniform airflow distribution. For example, at the connection of the flaps or in certain corners, the airflow may form vortices or have a slower flow velocity, resulting in inconsistent heat and moisture exchange at different parts of the electrode plate, which affects the curing and drying effect. Utility Model Content

[0004] The purpose of this invention is to provide a multi-layer flip-plate structure for an electrode plate curing and drying rack to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer flip-plate structure for an electrode plate curing and drying rack, comprising a main frame, flip-plate units, and an airflow distribution assembly. The main frame is a rectangular three-dimensional frame structure, in which multiple layers of flip-plate units are evenly distributed along the vertical direction. Each flip-plate unit is fixedly connected to the other by spacer support rods. Each flip-plate unit consists of several flip-plate modules. Each flip-plate module includes a base plate and flow guide side plates disposed on both sides of the base plate. The top surface of the base plate is provided with several positioning grooves for placing electrode plates. The bottom of the positioning grooves is provided with several vent holes that penetrate to the bottom surface of the base plate. The vent holes are arranged in a hexagonal honeycomb pattern.

[0006] Preferably, the airflow distribution component includes a flow guiding cavity disposed on the bottom surface of the substrate and a flow divider plate installed in the flow guiding cavity. The flow guiding cavity is a hollow cuboid structure, with its top surface fixedly connected to the bottom surface of the substrate and communicating with the vent holes. Air inlets are provided on both side walls of the flow guiding cavity, and the air inlets are connected to an external air source. The flow divider plate has a wave-shaped structure and is fixed in the flow guiding cavity. Several flow divider holes are evenly distributed on the surface of the flow divider plate, and the diameter of the flow divider holes gradually increases from the middle to both sides.

[0007] Preferably, the flow guide side plate has an arc-shaped structure, and its inner surface is provided with a number of strip protrusions. The strip protrusions are arranged at equal intervals along the vertical direction, and a flow guide channel is formed between adjacent strip protrusions. An adjustment mechanism connected to the main frame is provided on the outer side of the flow guide side plate.

[0008] Preferably, the adjustment mechanism includes a fixed seat, an adjusting screw, and a limiting block. The fixed seat is welded to the inner wall of the main frame. One end of the adjusting screw passes through the fixed seat and is rotatably connected to the guide side plate. The other end is provided with a handwheel. The limiting block is fixed in the middle of the adjusting screw and cooperates with the fixed seat to restrict the axial movement of the adjusting screw.

[0009] Preferably, the substrate has sealing strips on both sides of its edges, which are tightly fitted to the inner surface of the flow guide plate. The substrate has connecting ear plates at both ends, which are connected to the main frame via hinges. The connecting ear plates between adjacent flip-plate units are connected via linkage rods, and the linkage rods have bearing seats at both ends, which are fixed to the inner wall of the main frame.

[0010] Preferably, the diameter of the vent is 3mm-5mm, and the center distance between adjacent vents is 8mm-12mm.

[0011] Preferably, the cross-section of the strip protrusion is semi-circular, with a diameter of 5mm-8mm, and the spacing between adjacent strip protrusions is 10mm-15mm.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By setting a flow-guiding cavity with a flow divider at the bottom of the substrate, the incoming airflow is evenly distributed by the flow divider and then evenly distributed to the surface of the electrode plate through honeycomb-shaped vents. This effectively avoids the problem of uneven airflow distribution in traditional structures and improves the consistency of curing and drying. 2. The flow-guiding side plate adopts an arc design and is set with a flow-guiding channel formed by strip protrusions. With the adjustable angle structure, the speed and direction of the airflow can be precisely controlled, eliminating eddy currents and ensuring that all parts of the electrode plate receive uniform heat and moisture exchange. 3. The flipping units are synchronously flipped by a linkage rod. Combined with the use of sealing strips, this ensures the synchronicity of the flipping of multiple electrode plates and avoids airflow leakage, improving the stability and reliability of the equipment operation.

[0016] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 This utility model provides a technical solution: a multi-layer flip-plate structure for an electrode plate curing and drying rack, including a main frame 1, flip-plate units 2 and an airflow distribution component 3. The main frame 1 is a rectangular three-dimensional frame structure, and multiple flip-plate units 2 are evenly distributed in the vertical direction inside it. Each flip-plate unit 2 is fixedly connected to each other by a spacer support rod 4. The flip-plate unit 2 is composed of several flip-plate modules 5. Each flip-plate module 5 includes a base plate 6 and flow guide side plates 7 disposed on both sides of the base plate 6. The top surface of the base plate 6 is provided with several positioning grooves 8 for placing electrode plates. The bottom of the positioning grooves 8 is provided with several vent holes 9 that penetrate to the bottom surface of the base plate 6. The vent holes 9 are arranged in a hexagonal honeycomb pattern.

[0018] Specifically, the airflow distribution component 3 includes a flow guide cavity 10 disposed on the bottom surface of the substrate 6 and a flow divider plate 11 installed in the flow guide cavity 10. The flow guide cavity 10 is a hollow cuboid structure, and its top surface is fixedly connected to the bottom surface of the substrate 6 and communicates with the vent hole 9. The two side walls of the flow guide cavity 10 are provided with air inlets 12, which are connected to an external air source. The flow divider plate 11 has a wave-shaped structure and is fixed in the flow guide cavity 10. A number of flow divider holes 13 are evenly distributed on the surface of the flow divider plate 11. The diameter of the flow divider holes 13 gradually increases from the middle to both sides. Through the above arrangement, the airflow entering the flow guide cavity 10 can be evenly distributed to each vent hole 9 when passing through the flow divider holes 13 on the flow divider plate 11, and then evenly blown on the bottom surface of the electrode plate, thereby improving the uniformity of electrode plate curing and drying.

[0019] Specifically, the guide plate 7 has an arc-shaped structure, with several strip-shaped protrusions 14 on its inner surface. These protrusions 14 are equidistantly arranged vertically, forming a guide channel between adjacent protrusions. An adjustment mechanism 15, connected to the main frame 1, is located on the outer side of the guide plate 7. This design allows the strip-shaped protrusions 14 on the guide plate 7 to guide airflow along the guide channel during the rotation of the flip-plate unit 2, thereby increasing the contact area between the airflow and the side of the electrode plate and improving the drying efficiency of the electrode plate side. The adjustment mechanism 15 can adjust the angle of the flip-plate unit 2 according to actual needs to adapt to different electrode plate sizes and drying requirements, enhancing the flexibility and practicality of the electrode plate curing and drying rack.

[0020] Specifically, the adjustment mechanism 15 includes a fixed base 16, an adjusting screw 17, and a limiting block 18. The fixed base 16 is welded to the inner wall of the main frame 1. One end of the adjusting screw 17 passes through the fixed base 16 and is rotatably connected to the guide plate 7, while the other end is equipped with a handwheel 19. The limiting block 18 is fixed in the middle of the adjusting screw 17 and cooperates with the fixed base 16 to restrict the axial movement of the adjusting screw 17. Through the above arrangement, the operator can rotate the handwheel 19 to drive the adjusting screw 17 to rotate, thereby adjusting the angle of the guide plate 7 relative to the main frame 1. After adjustment, the cooperation between the limiting block 18 and the fixed base 16 can effectively prevent the adjusting screw 17 from moving axially, ensuring the stability of the flip plate unit 2 during the drying process.

[0021] Specifically, sealing strips 20 are provided on both sides of the substrate 6, and the sealing strips 20 are tightly fitted to the inner surface of the guide plate 7. Connecting ear plates 21 are provided at both ends of the substrate 6, and the connecting ear plates 21 are connected to the main frame 1 through hinges. The connecting ear plates 21 between adjacent flipping units 2 are connected by linkage rods 22. Bearing seats 23 are provided at both ends of the linkage rods 22, and the bearing seats 23 are fixed to the inner wall of the main frame 1. Through the above arrangement, when the flipping unit 2 rotates around the hinge, the linkage rods 22 can drive the adjacent flipping units 2 to rotate synchronously, realizing the linkage flipping of the multi-layer flipping units 2. The sealing strips 20 effectively prevent airflow from leaking from the gap between the substrate 6 and the guide plate 7, ensuring full utilization of airflow and uniformity of the electrode drying effect.

[0022] Specifically, the diameter of the vent hole 9 is 3mm-5mm, and the center distance between adjacent vent holes 9 is 8mm-12mm. Through the above settings, the airflow can pass smoothly through the vent hole 9, while ensuring sufficient drying area and optimizing the drying efficiency of the electrode plate.

[0023] Specifically, the cross-section of the strip protrusion 14 is semi-circular with a diameter of 5mm-8mm, and the spacing between adjacent strip protrusions 14 is 10mm-15mm. Through the above settings, the strip protrusion 14 can better guide the airflow, while increasing the contact time and contact area between the airflow and the side of the electrode plate, further improving the drying effect of the side of the electrode plate.

[0024] A specific application example of this embodiment is as follows: In use, the main frame 1 provides overall structural support. The flipping unit 2 is hinged to the main frame 1 via the connecting ear plate 21 to achieve the flipping function. The electrode plate is placed in the positioning groove 8 of the substrate 6. The airflow enters from the air inlets 12 on both sides of the guide cavity 10. After being diverted by the diverting plate 11, it is evenly distributed to the electrode plate surface above the substrate 6 through the vent holes 9. The strip protrusions 14 on the guide side plate 7 form a stable guide channel, guiding the airflow to flow in the vertical direction. The angle of the guide side plate 7 can be finely adjusted by the adjustment mechanism 15 to change the width of the guide channel, thereby controlling the airflow speed. Adjacent flipping units 2 are flipped synchronously through the linkage rod 22 to ensure the consistency of the flipping of the multi-layer electrode plates. The sealing strip 20 ensures the airtightness between the substrate 6 and the guide side plate 7 to prevent airflow leakage.
