Capacitor tunnel furnace

First, the structure of the tunnel oven structure in the capacitor industry:
1. Shell material: Made by high-quality stainless steel plate bending and welding;
2, liner material: SUS304 stainless steel plate to keep clean, anti-rust, corrosion resistance;
3. Box skeleton: It adopts angle iron welding to maintain the bearing strength of each surface of the box and retain the coefficient of thermal expansion and contraction to prevent deformation of the box.

4. Sealing material: The sealing strip is made of silica gel strip, which can resist temperature and deformation, and the door and liner adopt double-layer sealing form to enhance the sealing effect;
5, foot cup: 4 pieces of foot cups are installed at the bottom of the box to facilitate the fixing of the oven;
Second, the tunnel drying furnace control system:
1. Wind motor: It adopts long shaft wind motor and inverter;
2. Wind wheel: adopt 304# stainless steel multi-wing type wind wheel;
3. Heating tube: adopt 304# stainless steel U-shaped heating tube with heat sink to make the temperature of the heating tube evenly distributed;
Third, the tunnel drying oven features:
1. Over-temperature alarm: When the actual detection temperature exceeds the set value of the over-temperature protection thermostat, it is output to the customer PLC, and the heating power is automatically cut off to provide double protection function;
2. Grounding protection: safety grounding protection of structural parts.
3, power phase loss, phase sequence protection: with phase sequence protector;

Fourth, the main technical parameters of tunnel ovens in the capacitor industry
1, size: non-standard customization
2, temperature range: room temperature +20 ° C ~ +200 ° C adjustable, the use of temperature 150 ° C;
3. Instrument temperature fluctuation: ≤±1°C;
4, temperature uniformity: ≤ ± 2 ° C (no load) is less than or equal, load ≤ ± 4 ° C, measured temperature 10 minutes after feeding;
5, heating rate: ≤ 8 ° C / min;
6, the shell temperature: the equipment is within 150 ° C, the shell temperature is not higher than room temperature +15 ° C, except for the furnace mouth and joints;
7, the circulating wind mode: the upper and lower circulation of the wind;
8, power: three-phase five-wire system, 380V, 50HZ;
9, the total power: about 28KW.
