Description

Technical Field

[0001] The utility model relates to the technical field of protective equipment, in particular to a safety protection device for an infrared heating plate. Background Art

[0002] During the production process of lithium batteries, the solvent in the electrode needs to be heated to make it volatilize and solidify on the substrate. The traditional heating method is thermal oil, steam or electricity as a heat source. The air is heated and then the membrane is dried. During this period, there are multiple energy conversions, so the energy loss is relatively large.

[0003] Currently, infrared heating plates are used to radiate energy directly to the membrane coating through infrared waves, which increases the internal energy of the membrane molecules, thereby generating heat to volatilize the solvent. This heating method has low energy loss and high efficiency. However, in actual use, the infrared heating plates are mostly exposed, and their surfaces are charged and the temperature exceeds 400°C, which can easily cause electric shock and burns. The safety risk is relatively high, so protection is required. Utility Model Content
