Abstract
Description
Technical Field
[0001] This utility model relates to a drying device, specifically a lithium battery dryer. Background Technology
[0002] A lithium battery is a primary battery that uses lithium metal or lithium alloy as the negative electrode material and a non-aqueous electrolyte solution. It is different from rechargeable lithium-ion batteries and lithium-ion polymer batteries. Due to the highly reactive chemical properties of lithium metal, the processing, storage, and use of lithium metal require very strict environmental conditions. Lithium batteries are also affected by their own temperature during use. When the temperature is low, it will affect the activity of lithium ions in the lithium battery. In order to avoid the problem of low temperature affecting the normal use of lithium batteries, battery heating technology is usually used to heat them to reach a suitable operating temperature.
[0003] In the prior art, CN202222815265.X discloses a lithium battery heating device. This utility model discloses a lithium battery heating device, including at least two sets of high-frequency induction heating coils, a high-frequency induction heating controller, and a conveying mechanism. The two sets of high-frequency induction heating coils are sequentially arranged on the conveying mechanism, and each set of high-frequency induction heating coils is electrically connected to the high-frequency induction heating controller. This utility model's lithium battery heating device has a simple structure and is easy to use, heating the battery temperature by employing two sets of high-frequency induction heating coils.
[0004] In the existing technology, the batteries are preheated before entering the vacuum baking equipment, which can shorten the vacuum baking process time and improve production efficiency. However, this heating device cannot heat lithium batteries in batches, and the heating efficiency of lithium batteries is relatively low. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, this utility model provides a lithium battery dryer.
[0006] This utility model is achieved using the following technical solution: a lithium battery dryer, comprising a drying device, which is a drying chamber, a drying space, a drying platform, and a ventilation component, which is a ventilation trough, with a bottom pipe at the bottom of the ventilation trough. A heating device, which is a heater, is mounted on the bottom pipe, and the heater and the bottom pipe are interconnected. A diverter plate is mounted on the bottom pipe, located on the side of the bottom pipe.
[0007] The flow divider plate and the bottom pipe are fixed together by welding. The flow divider plate is distributed obliquely on the bottom pipe and is a rectangular flow divider plate.
[0008] The drying oven is equipped with an opening and closing component, which is an opening and closing door, and a hinge for opening and closing is provided between the opening and closing door and the drying oven.
[0009] A drying frame is provided on the drying platform, and a breathable round hole is provided at the bottom of the drying frame. A partition plate is provided inside the drying frame.
[0010] The partition plate is provided with ventilation holes, the drying frame is supported by the partition plate and a lithium battery is placed inside the drying frame, and the drying frame is provided with a traction handle.
[0011] Compared to existing technologies, this invention allows for the pre-drying of lithium batteries by placing them in drying frames before pushing them into a dryer. The dryer contains a drying platform with a heater at its bottom. The heater blows warm air to further dry the lithium batteries in the drying frames, resulting in a better drying effect and enabling the simultaneous drying of batches of lithium batteries.

Detailed Implementation
[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0018] A lithium battery dryer includes a drying device, which is a drying chamber 1. The drying chamber 1 has a drying space 2 inside. The drying chamber 1 has a drying platform 3 inside. The drying platform 3 has a ventilation component, which is a ventilation trough 4. The bottom of the ventilation trough 4 has a bottom pipe 5. The bottom pipe 5 has a heating device, which is a heater 6. The heater 6 and the bottom pipe 5 are interconnected. The bottom pipe 5 has a diverter plate 7 located on its side.
[0019] When lithium batteries need to be dried, they can be placed in a dryer for further drying. During drying, a heater 6 provides warm air to the dryer, effectively drying the batteries. The heater 6 delivers the warm air through the bottom pipe 5, but the air path needs to be redirected, especially when the warm air enters the bottom pipe 5. A diverter 7 directs the warm air upwards, allowing it to better penetrate the drying space 2. The diverter 7 is fixed to the bottom pipe 5 by welding. The diverter 7 is obliquely distributed on the bottom pipe and is rectangular. The diverter 7 effectively guides the warm air upwards, allowing it to travel further upwards.
[0020] The drying chamber 1 is equipped with an opening and closing component, namely an opening and closing door 8. A hinge is provided between the opening and closing door 8 and the drying chamber 1 for opening and closing. The opening and closing door 8 allows for good observation of the internal operation of the dryer. When lithium batteries need to be dried, they can be placed on the drying frame 9, which allows for batch placement of lithium batteries and avoids the problem of low drying efficiency of individual lithium batteries. The drying platform 3 is equipped with a drying frame 9, which has a ventilation hole at the bottom. A partition plate 10 is provided inside the drying frame 9, and ventilation holes 12 are provided on the partition plate 10. Lithium batteries are placed inside the drying frame 9 on the partition plate. The drying frame 9 is equipped with a traction handle 11. After the drying frame is dried, it will be quite hot. At this time, the operator can use the hook on the traction rod and the traction handle 11 to pull the drying frame 9 out of the dryer, making the operation safer for the operator.
[0021] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
