Description

Technical Field

[0001] This utility model relates to the field of dehumidification technology, and in particular to a lithium battery dehumidification device. Background Technology

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive and negative electrode materials and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, the processing, storage and use of lithium metal require very high environmental standards. With the development of science and technology, lithium batteries need to be dehumidified by a special baking device before use.

[0003] Existing lithium battery dehumidification devices use fixed spacing between the plates that hold lithium batteries. When the height of the lithium batteries to be processed exceeds the spacing, they need to be tilted, which reduces space utilization, decreases the number of lithium batteries that can be placed at one time, and reduces drying efficiency. Utility Model Content

[0004] This invention aims to overcome the problem in existing drying devices where the spacing between lithium battery placement plates is fixed, requiring the batteries to be tilted when their height exceeds the spacing, thus reducing space utilization and drying efficiency. The invention provides a lithium battery dehumidification device that allows adjustment of the vertical spacing of the placement plates according to the different height specifications of the lithium batteries.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A lithium battery dehumidification device includes a housing and a dehumidification assembly. A control panel is installed on one side wall of the housing. The interior of the housing is divided into an input chamber, a working chamber, and a dehumidification chamber from bottom to top. The input chamber, working chamber, and dehumidification chamber are interconnected. The working chamber is provided with several bosses and several movable placement plates. The bosses are fixedly connected to the inner side wall of the housing. The movable placement plates are placed on the tops of the bosses and are in contact with the bosses. The dehumidification assembly is located on one side wall of the housing and is connected to the housing. The dehumidification assembly is in communication with the input chamber.

[0007] The input chamber connects to the dehumidification unit, supplying hot air to the working chamber to dry the lithium batteries to be dehumidified. The working chamber is the drying area for the lithium batteries. The dehumidification chamber adsorbs moisture from the working chamber, keeping the gas dry during circulation and accelerating the drying efficiency of the lithium batteries. The boss is used to house the movable placement plate, whose position can be freely adjusted according to the height of the lithium batteries to be dried. This design allows for adjustment of the vertical spacing of the placement area according to different height specifications of the lithium batteries.

[0008] Preferably, the dehumidification assembly includes a fan and a duct. One end of the fan is fixedly connected to the housing, and the output end of the fan communicates with one end of the duct. A heater is installed inside the duct and is fixedly connected to the inner wall of the duct. The other end of the duct passes through the housing and communicates with the input chamber. Both the fan and the heater are electrically connected to an external power supply via a control panel. The fan blows hot air from the heater into the input chamber, and then into the working chamber, improving the drying efficiency of the device. This design improves the drying efficiency for lithium batteries.

[0009] Preferably, the input chamber is a sealed chamber with a gas outlet at its upper end. The input chamber communicates with the working chamber through the gas outlet, which connects the input chamber and the working chamber to dry the lithium battery. This design is used to dry the lithium battery inside the working chamber.

[0010] Preferably, the working chamber is equipped with a fixed placement plate located at the lower end of the boss and positioned near the input chamber. The fixed placement plate has several first vent holes and is fixedly connected to the inner wall of the housing. The movable placement plate has several second vent holes. The fixed placement plate is used to hold the first row of lithium batteries to be dried, and to position the bottommost placement plate, thus maximizing the space utilization of the drying area. This design improves the space utilization of the drying area.

[0011] Preferably, the working chamber is equipped with a temperature sensor and a humidity sensor, located above the boss and close to the dehumidification chamber. Both sensors are electrically connected to an external power supply via a control panel. The temperature and humidity sensors detect the temperature and humidity within the working chamber, allowing the fan and heater to stop operating promptly once the lithium battery reaches the dryness standard. This design saves time and improves work efficiency.

[0012] Preferably, the dehumidification chamber has a placement platform at its bottom, the platform having a U-shaped cross-section. The platform is fixedly connected to the inner wall of the housing. A dehumidification box is installed inside the dehumidification chamber, with mesh structures on its sides and bottom. The dehumidification box is placed on the placement platform and communicates with the working chamber through it. The dehumidification box and the placement platform are detachably connected. Activated carbon granules are placed inside the dehumidification box. A vent is provided at the top of the dehumidification chamber, connecting it to the outside of the housing. The vent is used for exhaust, and the dehumidification box is used for adsorbing moisture from the working chamber. This design adsorbs moisture from the working chamber, keeping the gas dry during circulation and accelerating the drying efficiency of the lithium battery.

[0013] Preferably, the dehumidification chamber has an open end for placing the dehumidification box, and a sealing ring is provided on the open end. The dehumidification box is sealed to the dehumidification chamber through the sealing ring on the open end, and a handle is installed on the outer side of the dehumidification box. This design facilitates the replacement of the dehumidification box.

[0014] Preferably, one side wall of the housing is provided with a door, which is hinged to the housing and matches the working chamber. A handle is installed on the outer side of the door. A locking plate is installed on the other side wall of the housing. The locking plate has an L-shaped cross-section and includes a horizontal plate and a vertical plate. One end of the vertical plate is fixedly connected to one end of the horizontal plate, and the other end of the vertical plate is hinged to the housing. A latch is provided on the door, and the horizontal plate is detachably connected to the latch on the door. The door ensures that the working chamber remains sealed during drying, the handle facilitates opening the door, and the locking plate secures the door in the closed position. This design guarantees the sealing of the working chamber during drying.

[0015] The beneficial effects of this utility model are: the vertical spacing of the placement plates can be adjusted according to the different height specifications of lithium batteries, thereby improving the drying efficiency of lithium batteries. Attached Figure Description
