High temperature tunnel oven 1set Ⅰ Technical Parameter The total length is 31 meters, of which the feeding area is 2 meters, the preheating area is 10 meters (temperature is 200℃), the high temperature curing area is 10 meters (temperature is
500℃), the cooling area is 6m, the feeding area is 3 m, and the width of the furnace is 1.5m (conveying bandwidth is 1.4 m). The total height of the furnace is 450 mm (the effective height is 350 mm), and the height of the conveyor belt is 0.8m from the ground.
Heating form and power: Natural gas heating form, 200 Kcal burner in preheating zone, 400 Kcal burner in high temperature solidification zone, 7.5 kw High temperature stainless steel hot air blower, 7.5 kw conveyor belt drive motor, 6 1.5 kw industrial cooling fans installed in cooling zone, total power consumption is about 31.5 kw.
Ⅱ Equipment configuration
① Insulation Layer: Made of our factory's special insulation layer, the thickness of the insulation layer in the preheating zone is 80mm, the outer layer is 1.2mm stainless steel grinding board, and the inner layer is 1.2mm stainless steel grinding board; the thickness of the insulation layer in the high-temperature solidification zone is 150mm, the outer layer is 1.2mm stainless steel grinding board, and the inner panel is made of our factory's special high-temperature fiberboard, and the insulation layer is filled with (120K) our factory's special insulation material. The heat preservation effect is excellent, the surface temperature of the furnace body is normal (±5℃), and the joint gap is slightly higher. The top of the furnace body is provided with an overhaul door for easy maintenance and cleaning of the furnace.
② Circulating ventilation system: 304 stainless steel high temperature circulating fan is used for ventilation, stainless steel plate is used for folding inside and outside the circulating air duct, and high temperature insulation material is filled in the middle. A dehumidification system is installed on the top of the furnace body. The exhaust gas and humidity are connected to the main exhaust gas pipeline and discharged outdoors through the induced draft fan.
③ Conveyor system: The conveyor motor is driven by Jin fu ling 7.5 kw frequency converter, and the speed is adjustable by Source Inverter. The speed is 0-5 m/min. It is also equipped with corresponding sprockets and other transmission parts, screw tension mode.
④ Line body and bracket: The main frame of the conveyor line adopts 100mm *50mm *3mm rectangular stainless-steel pipe, and the bracket adopts 50mm *50mm *3mm rectangular pipe, 1m per pipe.
⑤ Conveyor belt and chain: 304 stainless steel conveyor belts, width of 1.4 meters, high temperature resistance, corrosion resistance, durable type. The conveyor belt piercing rod adopts outer jacket inner diameter 12 mm, pipe center distance 152.4 mm, mesh hole 35x45, which ensures strength and won't be deformed under high temperature and long-term baking.
⑥ Cooling fans: 6sets of 1500W industrial cooling fans, designed as detachable, independent electronic control.
⑦ Electronic control box: control the start and stop of the conveyor line and the heating switch of the oven. The oven uses a temperature control meter to keep the temperature constant. It has the functions of PID temperature self-tuning and automatic constant temperature. Load control using Zhengtai contactor。
⑧ Surface treatment: The surface of the wire body is made of stainless steel, except galvanized and standard parts.
