Three-layer Automatic Vacuum Drying Oven For Battery Materials Baking

Three-layer Automatic Vacuum Drying Oven For Battery Materials Baking

1.Application Range of the Oven:

Suitable for drying lithium-ion battery electrodes,cells,and batteries prior to electrolyte injection.

2.Configuration:

A. Cabinet:Utilizes 3.0mm imported 304 stainless steel with reinforcement made from the same material.

B. Frame:Made from 1.5mm and 2.0mm quality cold-rolled steel plates,featuring a double-layer insulation construction including aluminum silicate,aluminum foil cotton,and soundproof cotton.

C. Control System:Consists of PLC,touchscreen,pressure sensor,high vacuum baffle valve,solid state relays,temperature controllers,solenoid valve assemblies,and more.

D. Hardware:Comprises doors,rear covers,vacuum pipes,and other stamped parts.

3.Machine Features:

A. Dual-layer insulation design,maintaining exterior temperatures below 45 degrees Celsius(excluding the glass door).

B. High vacuum pneumatic baffle valve,allowing triple-layer isolation and individual control.

C. Touchscreen interface for display and automation cycle control;also allows for maintaining vacuum pressure after the last step and displays safety temperature digitally.

D. Flexible double-glazed door,providing triple-layer pressure testing with overpressure protection.

E. Features multi-positional over-temperature protection for enhanced safety and precision in temperature control,effectively preventing temperature runaways.

F. The control screen features a user-friendly touchscreen interface for centralized operation;the PLC-based program controller ensures stable and reliable functioning.

G. Independent control for each layer of the oven,allowing for the setting of total bake time,cycle time,vacuum time,and drying time;executing automatic baking programs with the push of an auto button and shutting down automatically once the baking time is up.If the temperature surpasses the safety threshold,an alarm will activate,a red indicator light will illuminate,and the heating will stop while displaying an alarm message onscreen.

H. Automatic stop feature for inflation of dry gas into the chamber at any set value between-0.1Mpa and-0.02Mpa.

I. Regular work mode provides fault alert alarms and descriptions of fault reasons on-screen.

J. The vacuum pipes are designed to be corrosion-resistant.

K. Program interlock system to prevent gas crossover between layers.
