Power lithium battery quick drying machine

Abstract

The invention discloses a power lithium battery quick drying machine. The machine comprises a feeding mechanism, a drying box set and a discharge mechanism; the feeding mechanism is arranged at the left end of the drying box set, and is connected with the drying box set; the discharge mechanism is arranged at the right end of the drying box set, and is connected with the drying box set; the drying box set comprises multiple drying boxes; the multiple drying boxes are arranged adjacently in sequence; a feeding conveying line and an discharge conveying line for coaxial conveying are arranged among the drying boxes; the feeding mechanism is used for feeding lithium batteries; and the lithium batteries enter the drying box set through the feeding mechanism, and are conveyed among the drying boxes through the feeding conveying line or the discharge conveying line. The drying machine is provided with the multiple drying boxes, can realize synchronous working of the multiple drying boxes, improves the drying efficiency and the equipment utilization rate, and saves the cost; meanwhile, one drying box is provided with two ovens to achieve high capacity; and meanwhile, separate working of the two ovens in one drying box is realized, so that the working efficiency is improved, the intelligent automation degree is high, and meanwhile, the labor cost is reduced.

Description

technical field [0001] The invention relates to the field of dryers, in particular to a fast dryer for power lithium batteries. Background technique [0002] A lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Lithium battery manufacturing process requires very strict moisture content control, and the relative humidity of the manufacturing environment is required to be 5% or even lower. Even in such a low humidity environment, lithium battery equipment and semi-finished products in the middle still need to be removed through a vacuum drying oven. Trace amounts of moisture, the current production process of lithium batteries is complicated, the demand for labor is large, the utilization rate of manpower is low, the cost is high, and the efficiency is low. Moreover, it is easy to cause damage to the battery, such as sweat, which is easy to cause damage to the battery and...

Lithium battery manufacturing process requires very strict moisture content control, and the relative humidity of the manufacturing environment is required to be 5% or even lower. Even in such a low humidity environment, lithium battery equipment and semi-finished products in the middle still need to be removed through a vacuum drying oven. Trace amounts of moisture, the current production process of lithium batteries is complicated, the demand for labor is large, the utilization rate of manpower is low, the cost is high, and the efficiency is low. Moreover, it is easy to cause damage to the battery, such as sweat, which is easy to cause damage to the battery and affect the performance of the battery. Factory yield: use a drying box to place in the drying room environment, manually put the battery into the drying box, dry for more than 12 hours, then manually take the battery out of the drying room, and then put it into the liquid injection machine. There are many manual operations in the whole process. It takes too long, the main reason is that the heating adopts convection mode, which has a long heating time and slow efficiency, and the drying box often needs good heat insulation measures for constant temperature. The better the heat preservation measures, the more stable the temperature, but wait for the temperature to drop The longer the time, the longer the waiting time to cool down, the lower the utilization rate of the equipment. In order to improve the turnover rate of the equipment, some battery manufacturing units take out the baked battery materials in advance to cool them in the atmospheric environment, which will inevitably increase the baking time. The water absorption rate of the battery material, the higher the water content of the lithium battery product, the worse the performance

Therefore, the existing dryers have the disadvantages of low work efficiency, high labor costs, and low equipment utilization.
