Powder curing drying tunnel

1.1 Overview

Curing drying tunnel for fuel indirect heating hot air circulation drying tunnel. Include the insulation chamber body, the import and export plot,back to the wind pipe, the bottom frame, fuel heating systems, exhaust gas exhaust device and automatic temperature control system.

1.2 insulation chamber body and the import and export plot

Drying tunnel viaduct drying tunnel, import and export openings in the bottom of the drying tunnel, the workpiece out, the use of the principle of hot air rising from the bottom to reduce the door way heat leakage.

The chamber body unit of the laby rinth male and female tank flapper structure, site assembly. Wall material of galvanized steel, the outer wall of the color steel plate, the middle filled with fiber rock wool insulation, rock wool bulk density of 100 kg, the insulation thickness of 120 mm; the furnace insulation properties outside of the furnace plate surface temperature is not greater than the ambient temperature of 15 ° C.

The 1.3 return air pipe

Fuel drying tunnel

Next delivery next time back to the wind, the air hose set to adjust valve,easy to adjust the temperature field of the drying tunnel, to ensure the uniformity of the temperature field.

Back to the wind pipe all galvanized steel plate, thickness of 1.0mm production.

1.4 The bottom frame

The bottom frame is steel, plate, column, fasteners and other components.Column base plate with expansion bolts, the bottom of the bottom framein addition to install the hot stove for available space.

1.5 fuel heating system

Fuel heating system consists of a combustion chamber, stainless steel heat exchanger, circulating fan, imported fuel burners, automatic temperature control probe, light diesel fuel burners heat generated by the combustion of the combustion chamber through the heat exchanger indirectly transferred to the drying tunnel internal cycle by circulating fan, so that the internal temperature of the drying tunnel rising to the set temperature distribution uniform. while ensuring the drying tunnel heat air clean and pollution. burner used Italy Rielloburners, automatic control bake temperature and digital temperature control, combustion exhaust gas through the exhaust pipe excluded.
