150C Vertical Two Chambers Vacuum Drying Oven for Battery Electrode or Battery Core

I、 Introduction：

Vacuum Drying Oven is suitable for the vacuum baking process of battery electrode piece and battery cell to be injected in the production process of lithium battery. It adopts the industry-leading uniform temperature technology, the temperature fluctuation is ± 2 ℃; the vacuum cavity can be kept at - 0.098 MPa for more than 12 hours; multiple quality and safety protection are the ideal equipment to ensure the drying effect.

 

II、   Features：

A. Electrical features:

1. AISET three position PID temperature controller is selected for temperature control with high resolution.

2. The temperature measuring probe is specially made by Taiwan Valin, which is placed at the back of vacuum chamber to quickly and truly reflect the working temperature.

3. Triple over temperature protection device can cut off heating automatically when the temperature exceeds the set value to ensure the safety of materials and equipment.

4. Equipped with timing shutdown function, timing starts after constant temperature, automatically stops when baking time ends, and each layer can be timed independently.

5. The fan of each layer can be opened independently and can be used as cooling fan when heating is stopped.

6. Using high quality sus stainless steel seamless electric heating tube, heating up quickly, energy saving and durable.

 

B. Structural features:

1. The vacuum chamber is heated by hot air around the chamber, and the design of circulating air duct is innovated to ensure high-precision uniform temperature in the chamber.

2. The inner chamber is made of T3.0 mm high quality sus stainless steel, which is resistant to corrosion of battery slurry and electrolyte.

3. The multi-layer heat insulation material forms a closed insulation layer, which can block the heat loss and effectively solve the problems of adjacent warehouse temperature and external wall heating.

4. The door is double-layer toughened glass structure with over-voltage protection function. When the air pressure in the chamber is too high, it can automatically deflate, so that the air pressure in the chamber can be restored to the allowable range.

5. The vacuum chamber is equipped with a silicone sealing ring between the chamber and the door, and the chamber can be kept at - 0.098 MPa for more than 12 hours.
