[0002] Lithium batteries use lithium metal or lithium alloys as the negative electrode material and a non-aqueous electrolyte solution. Due to the highly reactive chemical properties of lithium metal, its processing, storage, and use place high demands on the environment. Lithium, plutonium, and other high-energy metals can corrode when exposed to atmospheric moisture, posing a fire hazard. However, dehumidifiers can maintain relative humidity below 1% in mass production areas, making lithium batteries viable and affordable for mass production.

[0003] Most of the existing lithium battery dehumidifiers are rotary dehumidifiers. Currently, most dehumidification wheels are connected to the dehumidifier by setting a rotating shaft in the middle to achieve the rotation of the dehumidification wheel. However, this connection method not only occupies the dehumidification space, but also makes maintenance and repair very inconvenient. Utility Model Content

[0019] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is described in further detail below with reference to embodiments and drawings, but the implementation manner of the present invention is not limited thereto.

[0020] like Figures 1-4 As shown, a dehumidifier for lithium battery production provided in this embodiment includes a dehumidification zone air duct 7, and a dehumidification wheel 13 is rotatably connected between the dehumidification zone air duct 7, a pulley 18 is fixed at the central position of the outer ring of the dehumidification wheel 13, and a roller 10 is slidably connected to the pulley 18 around it. The roller 10 is installed on a roller bracket 9, and the roller bracket 9 is welded to a wheel fixing frame 17. A wheel motor 8 is fixed to one side of the bottom of the wheel fixing frame 17 by screws, and the wheel motor 8 is driven and connected to the dehumidification wheel 13 through a belt 16.

[0021] Honeycomb-shaped filter holes are evenly arranged inside the dehumidification wheel 13, and a regeneration zone air duct 15 is fixed on the top of the dehumidification zone air duct 7. The filter holes are connected to the dehumidification zone air duct 7 and the regeneration zone air duct 15. The honeycomb-shaped holes are conducive to increasing the moisture absorption area of ​​the dehumidification wheel 13, and a solid desiccant is arranged inside the honeycomb holes.

[0022] A regeneration air intake motor 3 is fixed above one end of the regeneration zone air intake motor 15, and an air intake pipe 4 is screwed onto the input end of the regeneration air intake motor 3. A filter assembly is clamped in the inner wall of the air intake pipe 4, and a regeneration zone electric heating box 11 is sealed and connected to the output end of the regeneration air intake motor 3. The interior of the regeneration zone electric heating box 11 is heated by a resistance wire. The dehumidification zone air duct 7 and the regeneration zone air duct 15 are independent of each other and are not connected to each other.

[0023] A regeneration air outlet motor 2 is fixed above the other end of the regeneration zone air duct 15, and a regeneration exhaust duct 1 is sealed and installed on the input end of the regeneration air outlet motor 2. The regeneration zone air duct 15 is a fan-shaped structure, and the fan-shaped area angle is 90 degrees. Studies have shown that the dehumidification efficiency is best when the regeneration area of ​​the dehumidification wheel 13 is 90 degrees. A fresh air outlet filter plate 6 is clamped on the outside of the air inlet fan 14 and mainly filters out large particles of impurities in the air. An activated carbon filter plate is provided on the inside of the air inlet fan 14 and mainly filters out fine dust and bacteria in the air. A drying air outlet motor 12 is fixed to the other end of the dehumidification zone air duct 7.

[0024] An air inlet source box 19 is sealedly installed at one end of the dehumidification zone air duct 7, and an exhaust source box 20 is sealedly installed at the other end of the dehumidification zone air duct 7. An air inlet fan 14 is rotatably arranged inside the air inlet source box 19, and an air inlet motor 5 is installed on the outside of the air inlet fan 14. A drying air outlet motor 12 is installed on one side of the exhaust source box 20. A filter plate is clamped at the air inlet of the regeneration air inlet motor 3 to isolate impurities in the air. A regeneration zone electric heating box 11 is fixed on one side of the regeneration air inlet motor 3 to heat the incoming air.

[0025] The working principle of this device: When this device is in use, the rotor motor 8 drives the dehumidification rotor 13 on the roller 10 through the belt 16 to rotate 6-8 times per hour. During the rotation, the air drives the air inlet fan 14 through the air inlet motor 5, passes through the fresh air inlet filter plate 6 and the activated carbon filter plate in turn into the dehumidification air duct, and passes through the honeycomb flow channels on the dehumidification rotor 13. When the air enters the flow channel, the water vapor in the air will be absorbed by the desiccant in the flow channel and converted into dry air and discharged from the dry air outlet motor 12. As the dehumidification wheel 13 rotates, these honeycomb flow channels that adsorb water vapor will rotate to the fan-shaped regeneration area. The air enters through the air inlet pipe 4 and is filtered through the filter plate. The electric heating box 11 in the regeneration area heats the air flowing through it to 110°C to 130°C. The heated high-temperature air takes away the water vapor in the honeycomb flow channels when it flows through the regeneration, and drives out the moisture in the desiccant. As the dehumidification wheel rotates and desorption proceeds, the honeycomb desiccant flow channels restore their moisture absorption capacity and are rotated to the dehumidification area again. This cycle repeats itself, and the dehumidification process can be carried out continuously.

[0026] The above are only further embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention based on the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
