Four Drums Vacuum Drying Oven for Lithium Battery Electrode Making

Four Drums Vacuum Drying Oven for Lithium Battery Electrode Making

1.  Overview:

This product is specially designed for the vacuum drying process of the whole roll of electrode in the production process of lithium battery. It adopts the industry-leading uniform temperature technology, and controls the action process through the color touch screen and PLC, which is precise and reliable. It is an ideal equipment to ensure the drying effect, suitable for mass production of batteries, with good temperature uniformity, stainless steel liner, anti-corrosion, anti leakage and high quality.

2. Product features:

2.1. Select color touch screen and Xinje brand PLC to form a friendly and fast human-machine interface, which can realize automatic vacuuming, nitrogen filling, timing heat preservation, automatic shutdown and other actions or action cycles, original (Japanese) Panasonic digital display vacuum meter, 4 warehouses Independent control, independent display, no interference with each other.

2.2. The temperature control adopts Shanghai Yatai three-position PID temperature controller, which has high temperature control resolution.

2.3. The temperature measuring probe is placed at the back of the vacuum chamber, and the special model made by Taiwan Hualing is selected to quickly and truly reflect the working temperature.

2.4. Triple over-temperature protection device, each independently senses the temperature, and automatically cuts off the heating when the set temperature is exceeded, ensuring the safety of materials and equipment.

2.5. Each layer of air conveying fans can be turned on independently, and the blower can be turned on separately when the pole pieces are cooled to quickly cool down.

2.6. The use of high-quality 304 stainless steel seamless electric heating tube, heating up quickly, energy-saving and durable, life can reach 10-15 years.

2.7. Cylindrical cavity design, built-in circular shaft core ￠60 can suspend the entire roll of pole pieces, the shaft core can bear a maximum load of 380KG.

2.8. Adopt surrounding hot air to heat the vacuum chamber, and circular air duct to ensure high-precision and uniform temperature in the chamber.

2.9. The inner cavity material is T4.0mm high-quality SUS 8K mirror stainless steel, which is resistant to corrosion of battery slurry and electrolyte.

2.10. Multi-layer thermal insulation materials form a closed thermal insulation layer to prevent the loss of thermal insulation and effectively solve the problems of adjacent warehouse string temperature and outer wall heating.

2.11. The box door is a double-layer tempered glass structure with over-pressure protection function. When the air pressure in the cavity is too high, it can automatically deflate to restore the air pressure in the cavity to the allowable range.

2.12. A special high-temperature resistant silicone sealing ring is equipped between the vacuum chamber and the door, and the -0.098Mpa state in the chamber can be maintained for more than 24 hours.
