Tunnel drying oven (tunnel drying oven)
1、 Main technical parameters
The overall dimensions and specifications are approximately 8000m in length, 1.4m in width, 1.76m in height, and 0.2m in height at the feed inlet
Heating section length 6.8m, feed inlet width 1.0m, feed length 0.6m, discharge length 0.6m
The inner container measures 6.8m in length, 1.0m in width, and 0.2m in height, with three temperature zones independently controlled.  
The temperature range is from room temperature to+200 ℃, adjustable and constant temperature.  
Temperature uniformity ± 2% ℃ (under constant temperature state, no-load test)
Instrument temperature control accuracy ± 1 ℃, heating rate ≥ 8 ℃/min
The heat source stainless steel finned heating tube is electrically heated and operated horizontally.  
Power supply three-phase five wire system, 380V, 50HZ. Equipped with independent control electrical box power (approximately)
The total power is about 63KW. 2、 Structural characteristics of furnace body, shell material
Made of Q235T1.5 cold plate spray coating, bending and welding. Surface spraying treatment.  
Inner liner material 1 The inner liner is made of 1.5 thick SUS201 stainless steel plate with punched holes.  
Keep the inner container clean and dust-free, rust proof, and corrosion-resistant.  
 
Control system
Tunnel furnace temperature sensor K-type high-precision temperature sensor/screw type independent electrical control cabinet, with PLC+touch screen control for human-machine interface,
Other electrical accessories are sourced from high-quality brands such as Chint and Delixi.  
The main temperature control system adopts Taiwan Xuanrong H961 computer intelligent digital temperature controller and SSR/SCR solid-state relay output, equipped with PV and SV digital display windows for precise temperature control.
When the actual detected temperature exceeds the set value of the over temperature protection, the over temperature alarm automatically cuts off the heating power supply, providing dual protection function. Sound and light alarm with buzzer alarm device
Grounding protection structural components are equipped with safety grounding protection overload alarm, transmission overload protection function, motor short-circuit overload protection, power phase loss and phase sequence protection with phase sequence protectors,
Phase loss and reverse phase protection, other safety functions include fail safe reminders, leakage protection, motor thermal overload protection, over temperature power-off alarm, and transmission abnormality alarm. Emergency stop switches are installed at both the nose and tail of the aircraft.
