Production Machine of Fiberglass Chopped Strand Mat -Drying Oven

Production Machine of Fiberglass Chopped Strand Mat -Drying Oven
     The drying-oven is composed by a tunnel thermally isolated and furnished with a conveyor belt.
     The drying-section is heated by the direct-gas-fired system.
     The dryer is divided in zones. Each zone has a circulating fan and separate temperature controls.
1. Conveyor Belt
      The belt of the conveyor is a special stainless steel wire mesh, of the upper side, the mesh is supported by a series of rollers equipped with ball-bearings (outside of the oven).
      Cleaning brushes and cleaning burners are mounted on the conveyor belt.
      A belt guiding and tension system is provided. 
2. Ventilation
      Over and under the upper belt section are mounted special air-distributing cases. The upper ones are blowing and the under ones are sucking. 
      They are providing the rational distribution and the ventilation of the air all over the surface of the mat. under the sucking cases are mounted air-filters of mat or of veils.
      The motion of the air in each sector is provided by heavy duty ventilators with  special shovels.
      The construction of the ventilators and the air popes for the blowing and  sucking and the cases is realized in matter to make easily the cleaning operations.
3. Exhausted air
      In the sections, exhausters will provide for the exchange of the circulating air.
4. Air-Heating
      Each section is furnished with his own gas burner. After passing the material to dry, the hot air is sucked by the lower cases and therefore returns in cycle.
      The fresh air is sucked by holes with filters, opportuned placed on the sucking pipe.
5. Control Unit of The Burning and The Temperature
       Each burner is furnished with a set of controls for the temperature regulation. 
       Each set is composed by :
Temperature regulator
The thermo states of max. and min.
The timer for the burning cycle
The control U.V, photo cells
The servo control  for the flame modulation  
      For the circulating, the exhaust and the combustion air are foreseen control units of the pressure.
      All these units will be placed into a control-panel.
6. Thermal insulation cleaning and accessibility
      The drying tunnel is composed by a strong frame of iron U-profiles, covered with insulating panels, the hole structure is dis-assemblable.
      By planning the structure we have considered the thermal expansion and provided for the necessary. the insulating panels are manufactured with special iron sheets. 
      They are filled with glass wool.
      Along the sides of the oven, at a suitable distance, are mounted inspection doors.
      The distribution cases are furnished with openings to make easy the cleaning and maintenance.
