Description

Technical Field

[0001] This utility model relates to the technical field of supercapacitors, and in particular to a drying oven for the positive electrode material of a supercapacitor. Background Technology

[0002] Supercapacitors, a novel type of energy storage device, transcend the boundaries between traditional chemical energy storage power sources and conventional capacitors and batteries. They primarily store electrical energy through the charging and discharging mechanisms of redox pseudocapacitance and double-layer capacitance, enabling them to withstand hundreds of thousands of charge-discharge cycles without failure.

[0003] Existing supercapacitor cathode material drying ovens, such as the hot air circulating drying oven disclosed in utility model patent application number 202323059242.1, mainly include a box body with a placement frame inside. The placement frame is equipped with a drying cart and drying tray for placing cathode materials. A dehumidification structure is provided on top of the box body. In use, a dehumidifying adsorption wheel is used to dehumidify the incoming air, allowing fresh air with lower absolute humidity to enter the drying oven. This prevents fresh air with higher humidity from carrying moisture into the drying oven during the cooling process, thus reducing the moisture content of the cathode materials. By using the adsorption wheel for dehumidification, the absolute humidity of the outside air is reduced after passing through the adsorption wheel, keeping the fresh air circulation in the drying oven at a relatively low humidity. The outside air is filtered before entering the drying oven through a first filter.

[0004] However, most existing ovens require opening and closing the cabinet doors to place and retrieve materials, resulting in a significant loss of heat. Furthermore, the moisture inside the device is difficult to reuse once it is expelled with the air, leading to low energy utilization. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a supercapacitor positive electrode material drying oven that not only reduces heat loss during the loading and unloading process and improves drying efficiency, but also absorbs moisture from the air and heats the air, thereby improving energy utilization.

[0006] This utility model discloses a drying oven for positive electrode materials of supercapacitors, including a conveying mechanism; it also includes a sealing mechanism, a heating mechanism, a reflux mechanism, and a dehumidification mechanism. The sealing mechanism is installed on the conveying mechanism to reduce heat loss, the heating mechanism is installed on the sealing mechanism to deliver hot air to dry the positive electrode material, the reflux mechanism is installed on the sealing mechanism to recycle heat, and the dehumidification mechanism is installed on the reflux mechanism to absorb moisture from the air. The operator places the positive electrode material on the conveying mechanism, which then transports the material to the sealing mechanism. The heating mechanism is activated to deliver hot air into the sealing mechanism to dry and heat the positive electrode material. The humid air enters the dehumidification mechanism, which absorbs moisture and releases heat. The dehumidified and heated air then flows back into the sealing mechanism through the reflux mechanism to dry the positive electrode material.

[0007] Preferably, the conveying mechanism includes a workbench, a control cabinet, a conveyor belt, multiple sets of insulation partitions, and multiple sets of idlers. The bottom of the workbench is connected to the ground. The control cabinet and the conveyor belt are mounted on the workbench. Multiple sets of insulation partitions are mounted on the conveyor belt, and multiple sets of idlers are rotatably mounted on the workbench. The operator places the positive electrode material on the conveyor belt between two sets of insulation partitions. The control cabinet controls the conveyor belt to rotate, driving the positive electrode material into the sealing mechanism. By setting two sets of insulation partitions in conjunction with the sealing mechanism, heat loss is reduced, and the loading and unloading efficiency is improved. The idlers facilitate support for the conveyor belt and the positive electrode material.

[0008] Preferably, the sealing mechanism includes an insulated box, two sets of sealing strips, and two sets of uniform plates. The bottom of the insulated box is connected to the top of the workbench. The inside of the insulated box is provided with a cavity and has an inlet and outlet. The two sets of sealing strips are respectively installed at the inlet and outlet of the insulated box, and the two sets of uniform plates are installed on the insulated box. The two sets of insulation partitions block the inlet and outlet of the insulated box. The insulation partitions, together with the sealing strips, enhance the sealing effect of the insulated box and reduce heat loss. By setting two sets of uniform plates, hot air can be evenly delivered to the surface of the positive electrode material, ensuring the uniformity of drying.

[0009] Preferably, the heating mechanism includes a fan, an air inlet pipe, a filter bucket, and multiple sets of heating elements. The fan is mounted on the insulation box, the air inlet pipe is mounted on the fan and communicates with the inside of the insulation box, the bottom end of the filter bucket is communicated with the top end of the air inlet pipe, and the multiple sets of heating elements are all installed in the cavity of the insulation box. When the fan is started, the fan draws in outside air through the air inlet pipe and the filter bucket. The air is filtered through the filter bucket to prevent impurities from entering. After the air is delivered into the cavity of the insulation box, it is heated by the multiple sets of heating elements, and the hot air heats the positive electrode material.

[0010] Preferably, the reflux mechanism includes a dehumidification box, a reflux pipe, and a check valve. The dehumidification box is installed on the workbench and communicates with the interior of the cavity of the insulation box. The reflux pipe is installed on the dehumidification box and communicates with the interior of the top of the insulation box. The check valve is installed on the reflux pipe. The humid air in the cavity of the insulation box enters the dehumidification box and reacts with the dehumidification mechanism to dehumidify. The dehumidified air is then returned to the cavity of the insulation box through the reflux pipe. The check valve prevents air backflow.

[0011] Preferably, the dehumidification mechanism includes a drawer, a vent plate, and a handle. The drawer is slidably installed inside the dehumidification box, the vent plate is installed on the drawer, and the handle is installed on the drawer. The drawer is filled with calcium chloride. Humid air enters the drawer through the vent plate and reacts with the calcium chloride. The calcium chloride absorbs moisture from the air and releases heat to heat the air. The heated air is returned to the cavity of the insulation box through a return pipe. After a long reaction period, the operator pulls the handle to pull out the drawer to heat and dehydrate the calcium chloride, making it easy to reuse.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the operator places the positive electrode material on the conveying mechanism, the conveying mechanism drives the positive electrode material to the sealing mechanism, the heating mechanism is activated to transport hot air into the sealing mechanism to dry and heat the positive electrode material, the humid air enters the dehumidification mechanism, the dehumidification mechanism absorbs the moisture in the air and releases heat, and the dehumidified and heated air flows back into the sealing mechanism through the return mechanism to dry the positive electrode material.
