2, process overview
The entire coating line consists of three parts: automatic transmission lines, economic and environmentally friendly powder coating booth, energy-saving curing oven.
2.2.1, powder booth with recycling ; six-cell the filter recovery unit 2 sets; using pulse-jet cleaning cartridge recycling. Outdoor emissions, operation and color change;
2.2.2, curing oven structure bridge U-furnace; bridge furnace, heat exchangers, heat circulating fan, the thermal cycling duct, exhaust pipe, frame sections;
Drying tunnel insulation board assembly "sandwich" structure. Drying tunnel heating with hot air circulation.
The heating chamber is provided in the lower part of the cabinet.
Curing drying tunnel temperature of 200 ° C, the temperature can be adjusted continuously, the highest temperature up to 220 ° C curing. Drying tunnel heating time by 40 minutes to heat up to 210 ° C design.
Drying tunnel heating chamber with fan access door and the heat exchanger access door to facilitate the heated indoor equipment maintenance and installation.
2.2.3, works:
Bridge curing oven: for continuous curing of the workpiece and the collection of the hot air, to prevent or minimize heat spillover;
Heat exchangers: for the heating of hot circulating air to promote and accelerate the curing of the workpiece;
Heat circulating fan: for after the curing of the cooling air is recovered through the fan is then pressed to the heat exchanger is heated and fed into the curing oven, and through the distribution duct, and evenly distributed in the curing oven the new laborers;
Thermal cycling duct: control the flow of air to prevent heat from spill;
Exhaust pipe: spillover in the mouth of the tunnel furnace exhaust gas through the directional pipe emissions for outdoor;
2.2.4 Process:
Powder production line: Loading manual → preheating → powder coating → curing (about 20 minutes) → cooling → Manual unload;
In the premise of ensuring the performance of the original equipment used to minimize the underlying investment.
