3 Layers Large Capacity Energy Saving Type Vacuum Drying Oven




1、 Basic structure

 It consists of 5 parts:

1.   Rack section;

2.   Internal cavity part;

3.   Vacuum pumping and nitrogen filling section;

4.   Electrical control part;

5.   External circulation section;


2、 Operational principle

Each machine can work continuously in a cycle; Basic process: Open the door and put the battery or electrode into the oven, then set the heating time, vacuum time, and nitrogen time. The system will automatically complete the heating and timed air exchange according to the set time parameters, completing the baking process.


3Configuration

3.1Inner cavity: Made of 3.0mm stainless steel, with reinforcing ribs made of iron square material

3.2Rack: Made of 1.5mm high-quality cold-rolled sheet, consisting of two layers of insulation, with cotton made of three layered materials: aluminum silicate, aluminum foil cotton, and sound insulation cotton

3.3Hot air system: Each layer is composed of fans, heating boxes, air ducts, air ducts, etc., which can better achieve temperature consistency

3.4Control system: composed of PLC, touch screen, pressure sensor, high vacuum baffle valve, solid-state relay, temperature controller, electromagnetic valve group, etc

3.5Hardware components: including doors, back covers, vacuum tubes, and other stamped parts, etc


4Machine characteristics

4.1. Door opening method: single door opening; Elastic double-layer glass door, three-layer pressure detection, with overvoltage protection function;

 4.2 Inner liner sealing ring: Silicone rubber O-ring made by pouring mold, resistant to high temperature and corrosion

4.3 Principle: Surrounding hot air external circulation. Double layer thermal insulation, with an external temperature not exceeding room temperature+20 degrees;

4.4 Heating structure: Adopting O-shaped external circulating air, with left side air outlet and right side air suction, achieving temperature consistency;

4.5. High fidelity pneumatic baffle valve, isolated three-layer independent control;

4.6. Touch screen display, automatic cycle and automatic control, completing the final step and returning to vacuum holding pressure; Digital safety temperature display;

4.7. Equipped with a multi position overtemperature protection temperature control device, it can effectively prevent temperature control safety issues such as temperature loss, and improve the accuracy of overtemperature protection;

4.8. The control screen adopts a touch screen for centralized operation, which is convenient to operate and reliable to control. The program controller adopts PLC control, which works stably and reliably;

4.9. The three-layer oven is individually controlled, and the total baking time, cycle time, vacuum pumping time, and drying time can be set separately. After setting the parameters, the automatic button can be pressed to enter the automatic baking program. When the time reaches the baking time, it will automatically shut down. If the temperature exceeds the safe temperature value, an alarm will be triggered and the red indicator light will light up, and heating will automatically stop. The alarm information will be displayed on the display screen;

4.10. Fill the box with dry air to any set value between -0.1Mpa and -0.02Mpa, and the inflation can be automatically stopped;

4.11. During normal operation, the fault prompt alarm and the cause of the fault can be described on the screen;

4.12. Vacuum tubes have anti-corrosion properties;

4.13. Program interlocking to prevent inter layer gas leakage.
