Description

Technical Field

[0001] This utility model relates to the field of lead-acid battery production technology, and in particular to a lead-acid battery plate curing device. Background Technology

[0002] Lead-acid batteries are widely used in various fields. Among them, the battery plates directly determine the battery performance. In addition to the plate formulation itself, the plate curing quality is also an important factor affecting plate performance. Currently, plates are often stacked during curing. During the curing and drying process, the top layer of plates on a stack dries 5 to 10 hours less than the middle layer. After drying, plates are prone to defects when stored in a high-temperature environment, such as plate cracks and poor coating adhesion.

[0003] To overcome the above shortcomings, a search revealed that authorized announcement number CN209929407U describes a lead-acid battery plate curing device, which includes a curing chamber with a closed door at the front end. The left and right side walls of the curing chamber are provided with two or more sets of air inlet ducts corresponding to each curing rack, arranged sequentially from bottom to top. The width of the air inlet ducts on the left and right side walls decreases sequentially from bottom to top. Each set of air inlet ducts includes multiple ducts corresponding one-to-one with each layer of battery plates on the curing rack. Furthermore, the width of the middle air inlet duct in each set is greater than the width of the lower air inlet duct, and the width of the lower air inlet duct is greater than the width of the upper air inlet duct. This ensures that each battery plate layer has a corresponding air inlet, maximizing the air intake utilization rate of the curing chamber, shortening drying time, and improving production efficiency.

[0004] However, the above solution uses the adjustment of the width of the air inlet to ensure the efficiency of the drying work, which is insufficient to improve efficiency and does not make high space utilization. At the same time, the cavity will also lead to increased heat loss, which will have a certain impact on work efficiency. Utility Model Content

[0029] Please see Figures 1 to 9 This utility model provides a technical solution:

[0030] A lead-acid battery plate curing device includes a curing chamber 10, a base 7, curing frames 3, a gas handling element, a sealing door 18, an air inlet pipe 2, and an air outlet 1. The curing chamber 10 contains four sets of curing frames, each set consisting of two or more curing frames 3. Battery plates 19 are placed sequentially from left to right on each curing frame 3, with each battery plate 19 spaced apart to ensure sufficient curing time for each battery plate and a high yield rate. The air inlet pipe 2 is installed above the curing chamber 10 to allow air to enter the chamber. The curing chamber 10 has a circulation structure that directs air through the air inlet pipe 2. The curing chamber 10 is circulated with air through a gas treatment element to ensure that each battery electrode 19 is dried and cured by the high-temperature gas. The lower end of the curing chamber 10 is provided with a base 7 for placing the curing frame 3. The lower part of the base 7 is provided with a rotating component 4 for driving the base 7 to rotate. The rotation of the base 7 drives the curing frame 3 and the battery electrode 19 placed in the curing frame 3 to rotate, so that the battery electrode 19 is evenly dried by the high-temperature gas blown out of the air outlet 1. The front end of the curing chamber 10 is equipped with a sealing door 18 to seal the curing chamber 10 and ensure that the high-temperature environment inside the curing chamber 10 is not affected by the outside.

[0031] In specific implementation, it should be noted that the circulation structure includes an air outlet 1, an air intake 8, a central air outlet duct 6, a dryer 5, a heating element 9, an air inlet 20, and an air outlet 21. The air outlet 1 and the air intake 8 are evenly distributed on the inner wall of the curing chamber 10 to ensure that each curing frame 3 receives the same amount of hot air. The air outlet 1 is connected to the air inlet 20, and the air intake 8 is connected to the air outlet 21 to ensure gas circulation. The dryer 5, heating element 9, air inlet 2, and air outlet 14 are installed above the curing chamber 10. The gas circulation first involves the air inlet 14 drawing in external air. The air is delivered to the curing chamber and then the air inlet pipe 14 is closed. The air inside the curing chamber 10 is first dried by the dryer 5 and then heated by the heating element 9 to form high-temperature gas. It is then delivered to the air outlet 1 through the air inlet 20 to enter the curing chamber for curing. The gas that is no longer dried after passing through the battery electrode 19 is drawn into the air outlet 21 through the air inlet 8 and blown into the dryer 5 by the blower 16 for drying. After being heated by the heating element 9, it participates in curing again to form a cycle. The air inlet pipe 2 is connected to the air inlet 20 and the air outlet pipe 14 is connected to the air outlet 21 to facilitate the discharge of the gas inside the curing chamber 10 after curing is completed.

[0032] In the specific implementation process, it should be noted that the central air outlet duct 6 is installed at the center of the curing chamber 10. The central air outlet duct 6 is connected to the air inlet duct 20 in the upper wall of the curing chamber 10. The central air outlet duct 6 has central air outlets 601 evenly distributed on it, which can blow the circulated high-temperature dry gas evenly onto the battery electrode 19 to improve efficiency. The central air outlet duct 6 is spaced from the lower base 7 so that the central air outlet duct 6 is not affected when the base 7 rotates, ensuring that the curing time of each group of battery electrode 19 is the same.

[0033] In the specific implementation process, it should be noted that a base 7 and a rotating component 4 are installed below the curing chamber 10. The rotating component 4 is located below the base 7 and is used to drive the rotation of the base 7. The rotating component 4 includes a motor 401 and a connecting rod 402. The motor 401 is located at the center inside the base 7 and is connected to the connecting rod 402. The connecting rod 402 connects the motor 401 and the base 7. The rotating device is electrically driven and the rotation speed can be controlled to ensure the curing effect. The rotation of the base 7 drives the curing frame to rotate, which improves the quality of the battery electrode curing process. A fixing groove 12 is provided above the base 7 for installing and stabilizing the curing frame 3 to ensure the stability of the curing frame 3 and the battery electrode 19 inside during the rotation of the base 7.

[0034] In the specific implementation process, it should be noted that the curing frame 3 includes a U-shaped groove 303 at the bottom, a frame crossbar 301, and a frame column 302. The frame crossbar 301 is connected to the frame column 302, and the frame column 302 is connected to the support foot 11. The U-shaped groove 303 at the bottom is connected to the frame crossbar 301 below the curing frame 3. The frame is welded to ensure safety and stability, and to ensure the safety of the battery electrode sheet during the curing process. The frame crossbar 301 and the frame column 302 are connected in pairs and have less obstruction on all sides, which increases the contact area between the battery electrode sheet 19 and the circulating dry high-temperature gas, and improves the utilization rate of the circulating gas.

[0035] In the specific implementation process, it should be noted that the bottom of the frame column 302 is a support foot 11, and the inside of the support foot 11 is a mounting hole 13. When using it, the battery electrode 19 is first arranged and fixed on the U-shaped groove 303, and then the curing frame 3 is arranged and fixed upward in sequence. The battery electrode U-shaped groove 303 is used to place the battery electrode 19 and to separate adjacent battery electrode 19, so that the circulating high temperature gas can pass through, thereby improving the curing efficiency of the battery electrode and ensuring that the curing effect tends to be consistent, thus ensuring the curing yield.

[0036] In specific implementation, it should be noted that the curing chamber 10 is cylindrical in shape to improve the utilization rate of the internal space, and an insulation layer 15 is provided inside the wall to ensure a high-temperature environment inside the curing chamber 10 and improve curing efficiency. An exhaust fan 16 and an intake fan 17 are installed below the air inlet pipe 2 and the air outlet pipe 14, respectively. The exhaust fan 16 is installed below the air inlet pipe 14, and the intake fan 17 is installed below the air inlet pipe 2. This can be used for gas to enter and exit the curing chamber, and also to increase the circulation rate of the high-temperature gas inside, thereby improving working efficiency.

[0037] The remaining parts not described in this utility model are existing or known technologies.

[0038] 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.
