Technical Field
[0001] The utility model relates to the technical field of lithium battery recycling, in particular to a drying device for recycling lithium batteries. Background Art
[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses a non-aqueous electrolyte solution. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium metal batteries generally use manganese dioxide as the positive electrode material, metallic lithium or its alloy metal as the negative electrode material, and use a non-aqueous electrolyte solution. Lithium ion batteries generally use lithium alloy metal oxides as the positive electrode material, graphite as the negative electrode material, and use a non-aqueous electrolyte.
[0003] The patent with application number 202022532309.9 discloses a lithium battery recycling and drying processing device, including a base, a shell and a heating box are fixedly connected to the upper side of the base, two first plates are fixedly connected to the upper side of the shell, a second groove is opened in the middle of the first plate, and the second plate is slidably fitted in the second groove, and a connecting plate is slidably fitted on one side of the second plate, and the lower sides of the two connecting plates are respectively fixedly connected with a first tray and a second tray, a first groove is opened in the middle of the first tray, a cover plate is installed on the upper side of the connecting plate, tooth plates are fixedly connected on both sides of the cover plate, and two slide grooves are opened on the lower side of the cover plate, a suction pipe is fixedly connected to one side of the heating box, and a hair dryer is installed on one side of the suction pipe.
[0004] The lithium battery recycling and drying device can adjust its width according to the size of the lithium battery, thereby improving the convenience of the drying device. Gears are arranged on both sides of the shell, and the gears are engaged with the toothed plates so that the cover plate drives the first tray and the second tray to open or close, which is convenient for taking out the lithium battery, thereby improving the speed of taking out the lithium battery. However, there are still areas that can be improved. For example, when the device takes out the lithium battery, the cover plate is lifted, causing a large amount of heat inside the shell to be lost, resulting in a waste of energy. The next time the lithium battery is dried, it needs to be reheated, resulting in low drying efficiency and being unable to meet current needs. Utility Model Content
