2, process overview

The entire coating line by automatic conveyor line, dusting rooms of the economic environment-friendly, energy saving curing oven.

2.1, spray booth with recovery; 8 core the filter recovery unit 2 sets; galvanized sheet production.

     Using pulse-jet cleaning cartridge recycling.Filter imported 220g polyester, can be washed.

Powder spray booth  features:

Configuration: 16 cartridge filter Φ320 * 900 ,8 / units total, matching 16 sets of 1-inch pulse valve; the import speed design to 0.6m / s, the minimum to 0.5m / s, to ensure that the powder does not spill.

Supporting air bag Φ219 * 2000 units; the supporting fan (4): 4-72 No. 6A 1450r/min Q <13353m3 / h H> for 724pa kw = 4.0kw low noise high efficiency fans;

Outdoor emissions convenient operation and color change;

The painting room airflow Combo features in the form of the first part of the painting operating room after the mist clean room. Its principle: air enters at the front from the paint spray booth spray booth, take away not adhere to the mist on the workpiece, the water curtain and curtain scrub filtering, washing mist contained in the air after the mist clean room , and finally through the exhaust fan discharge clean air.

Spray booth features:

 using the three curtain segmented ventilation and air washing, ensure that work throughout the indoor air and wind speed uniform treatment;

Labyrinth baffle plate separator, the current state-of-the-art processing methods, allows air containing mist and fog through the four 180O fold stream, by high-speed centrifugation adhesion than air than the major things in the fold flow board;

2.2, curing oven structure in the form of U-shaped bridge furnace; bridge furnace, heat exchangers, heat circulating fan, the thermal cycling duct, exhaust pipe, frame sections;

Drying tunnel insulation board assembly \"sandwich\" structure. Cabinets supply duct with δ0.8 zinc steel plate, the insulation board machine Caigangyanmian board, beading on both sides, the outer surface color spraying insulation thickness of 120mm.

Drying tunnel heating with hot air circulation. Its advantage is that a uniform temperature within the drying tunnel, along the cross section of the track,, workpiece and 3.4, the temperature difference is less than ± 5 ° C, so as to ensure color consistency of the workpiece coating.

The heating chamber is provided in the lower part of the cabinet. Hot air circulation, circulating the air supply, the next time the wind, eliminating the need for return air and outside air return pipe to reduce heat loss. Drying tunnel units Y9-19-4A-type induced draft fan, power 3.0KW / Taiwan. Airflow: 1700m3 / h.

Curing drying tunnel temperature of 220 ° C, the temperature can be adjusted continuously, the highest temperature up to 240 ° C curing. Drying tunnel heating time of 45 minutes to heat up to 220 ° 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.

2.3 Principle:

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;
