Product Description
1. Powder coating line design
Â
2. Process flow diagram
This line consists of powder coating chamber, booth, curing bake, suspend conveyor and electric control system.
Â
3. Curing bake
Â
The drying tunnel consists of three parts: drying tunnel. Heating system and exhaust system.
Â
2.heating system: consists of heating chamber, burner, heated air recycling fan, return airway and temperature control system.
(1)heating room:Â an access door is on the side of the heating chamber for future repairing.
Â
(2)Â burner
1Â set, 300000 calories
Gas consumption: 10-15m3/h
Brand: Italian Riello RS34
Â
(3)burning tank
Heat exchanger is used to transfer the heat to heating room, then hot-air blower will bring the heat to the tunnel. Adopts direct-fired heating, the burning tank is stainless steel with high temperature filter.
Â
Â
(5)Â Air delivery & returning duct
Â
(6) Temperature control system
Drying tunnel uses digital temperature controller to adjust the temperature automatically, it can display and control the drying tunnel temperature in real-time.
The temperature measurement uses platinum resistor temperature sensor.
The drying tunnel temperature can be adjusted continuously from normal temperature to 200°C.
Â
3. Exhaust pipe
The entrance/exit of the drying tunnel on the top equips with exhaust pipe and  butterfly valve, it is used for draining the exhaust gas of the drying tunnel.
The material of the exhaust pipe is δ1mm galvanized sheet.
Â
4. Hang type conveyor
Hang type conveyor consist of driving device, tension device, variable-frequency governor, chain, straight conveyor, bend conveyor, temperature flexible conveyor, inspection conveyor and lubrication system etc.
Variable -frequency governor uses Mitsubishi. The speed is 1.4 m/min.
The lubrication system uses automatic oil drop device.
Hang type conveyor equips with 1 set driving device, 1 set weight-loaded type tension device, using frequency to adjust speed.
