Ii. Temperature control system
1. Temperature range: room temperature -- 250 ° c (the required temperature can be arbitrarily set)
2, temperature controller: RKC 70 temperature controller, LED digital display
Set, PID automatic calculation and correction set, with 0.6 core electrothermal couple and contactor output
To ensure more stable and accurate temperature control.
3. Accuracy of the thermostat: ±5℃
4. Temperature uniformity: ±5℃ (upper, middle and lower test of heating empty furnace)
5, add heat exchanger: adopt Φ 11 mm cooling type dry type heat pipes (high temperature and the resistance of the wire imported stone
The heating pipe is arranged on both sides of the furnace
Iii. Transportation risk control system:
1. Wind motor: a special motor for strengthening shaft type oven and a powerful multi-wing wind wheel are equipped
2. Mode of air transportation: forced air out on both sides of the furnace body and air back circulation on the top.
At the top of the furnace body is equipped with exhaust chimney, so that when the product is baking, exhaust fumes can be discharged in time
Iv. Furnace structure and materials:
1. The furnace body is designed as: single door.
2. The inner box is made of 0.8mm unembroidered steel plate.
3. The outer box shall adopt 1. Mm thick A3 cold plate for rust prevention after forming, and spray the computer white.
4. Thermal insulation material: it is made of CSR 80K environmental friendly high temperature cotton with a thermal insulation thickness of 80mm
5, door side seal: high temperature resistant silicone forced tight seal
5. Materials for controlling electrical appliances:
Temperature meter: 1 (Taiwan RKC)
Electric couple: 1 (0.6-core k-type)
Time system: 1 set (enough temperature timing)
Wind motor: 1 set (600W)
Wind turbine: 1 12"
Contactor: 1 set (10A)
Power switch: 1 (12A)
Power supply, heating, timing, control twist, switch: 1 set
Vi. Safety system:
1. Motor phase loss over-current protection device (when the motor is overloaded, cut off the heating power to prevent the product from being damaged)
2, control circuit short circuit and overload protection, when the circuit short circuit or other faults cut off the power, to protect the safety of the motor
Vii. Working principle of the machine:
1, start the power off →2, open the motor air switch →3, open the heating switch →4, set the station
Required temperature →5, start heating →6, automatically calculate the baking time when the temperature reaches the beginning →7, start beeping when the baking time reaches, and cut off the heating power.
