Curing drying tunnel is a ring drying tunnel that is heated directly by fuel gas. It has a set of fuel gas heating system and independent hot air circulating design.

1) Structural composition and features of curing drying tunnel:

(1) Drying tunnel consists of the main part of drying tunnel, hot air circulating system and exhaust emission system. A reasonable hot wind flow direction can be formed in drying tunnel with a reasonable layout. Besides, hot air overflowing to the workshop can also be avoided effectively, by which not only energy sources can be saved, but also environment being protected. Exhaust emission system can discharge the exhaust gas from the furnace.

 

   (2) Tower structure is used for the drying tunnel.

 

(3) The blowing-in layout of hot air circulating system is up-return down-supply interconversion. Air supply outlet is set below the workpiece, and return duct is set upside the drying tunnel. A reasonable hot wind flow direction can be formed in the drying tunnel with a reasonable layout of air supply outlet and return air inlet under natural lifting power of hot air. Thus, an effect of well-distributed heating for the workpiece, good economical efficiency for air supply and reasonable air distribution can be reached. Air supply outlet is flexible and adjustable. By means of adjusting the blast capacity of air supply outlet, the air output can be changed in each stage, thereby the temperature is well-distributed in the drying tunnel. The wind adjusting plate of air supply groove is made from galvanized sheet.

 

(4) In order to guarantee the surface quality if workpiece, hot wind filter system is set specially. A thermal cycle air filter is set in air supply outlet that the dust produced in the cyclic process can be filtered. The filter layer is a 5-layer stainless filter net, the thickness of filter is 30mm and the initial resistance is less than 200pa. air filter is dismountable to have the operations of maintenance and ash removal. Therefore, the quality of air supply and coating can be guaranteed.

 

   (5) In order to reduce heat output in the outlet of drying tunnel, a set of heat insulation area is set in the outlet of drying outlet to reduce energy        consumption and protect the working environment.
