The Round Vacuum Oven is dedicated to the Li-ion battery electrode drying process for producing. The vacuum oven working chamber is equipped with cylindrical cantilever, can hang the whole roll electrode, with maximum bearing weight up to 380 kg.
The 4 Round vacuum oven is equipped with four drums, you can also choose single drum, two drum according the battery production line output.
It is suitable for baking the whole roll of battery electrodes.
Adding temperature control ports for over-temperature protection can effectively prevent safety problems such as temperature runaway.
Each machine can work in a continuous cycle; basic process: open the oven door, put the electrode or battery into the oven, and then set the heating time, vacuum time, and nitrogen time. The system will automatically complete heating and regular ventilation according to the set time parameters to complete the baking process.
Vacuum drying oven configuration
1 Box material: stainless steel, reinforced with square materials
2. Frame: Made of 1.5mm and 2.0mm high-quality cold-rolled plates, it is composed of two layers of thermal insulation cotton. The cotton is produced in three layers: aluminum silicate, aluminum foil cotton, and sound insulation cotton.
3 Hot air system: Each layer is composed of fans, heating boxes, air ducts, air ducts, etc., which can achieve temperature consistency
4. Control system: composed of PLC, touch screen, pressure sensor, high vacuum baffle valve, solid state relay, temperature controller, solenoid valve group, etc.
5 Hardware: including doors, back covers, vacuum tubes and other stamping parts
Vacuum drying oven features
1. Fully enclosed heating channel, breathing heating process, high efficiency, energy saving and high temperature accuracy.
2 high vacuum pneumatic gate valves, isolated and controlled individually by four chambers.
3 The entire series is equipped with six high-performance safety devices as standard.
4. The entire series comes standard with aluminum alloy doors, elastic double-glazed doors, excellent heat storage and explosion-proof performance, three-layer pressure detection, and overpressure protection;
5. The entire series is equipped with a 7-inch color large-screen PLC operating system as standard, which is beautiful and elegant.
6. Loading method: ¢63 hanging shaft is hung in the middle of the liner, and the hanging load-bearing capacity is ≤200Kg.
7 Box structure: four doors and single door (4 doors).
8 Insulation layer structure: high-density aluminum silicate insulation cotton, double-layer insulation, external temperature is less than 45 degrees (except glass doors)
9 Heating method: electric heating control, surround hot air circulation.
10. Heating structure: O-type external circulation air, air outlet on the left side, air suction on the right side, with good temperature consistency.
11. Touch screen display, automatic cycle control, complete the last step to return to vacuum pressure; digital display of safe temperature.
12 Equipped with a multi-position over-temperature protection temperature control device, which can effectively prevent temperature control safety issues such as temperature control and improve the accuracy of over-temperature protection. 13 The control panel adopts touch screen for centralized operation, which is easy to operate and reliable. The program controller adopts PLC control, and the work is stable and reliable.
14 The four-barrel oven is independently controlled. The total baking time, cycle time, vacuum time, drying time, and parameter settings can be set independently. You can press the button to automatically enter the baking program. When the time reaches the baking time, it will automatically shut down. If the temperature exceeds Set the temperature, an alarm will automatically sound and the red indicator light will light up, and the heating will automatically stop, and the alarm message will be displayed on the display.
15. During normal operation, fault alarms and fault causes can be described on the screen, and equipment information can be fed back in real time.
