Rotary screen fabric dye machine for knitted or woven fabric dryer
KD-R456 type rotary screen dryer
This machine has overfeeding device, suitable for drying knitted
fabric and woven fabric.
Rotary (part 1) is punching cylinder, half of the rotary screen is
blocked by seal plate (part 2). Two neighboring rotary screens
counter rotate, seal plate is fixed. The air, after heated in
heater (part 4) by centrifugal fan (part 3), through guide
plate(part 5) into grey fabric layer(part 6) for circulation, guide
plate(part 5) uniformly distributes hot air along the grey fabric
width direction. Grey fabric delivered to first rotary screen
through transport lattice (part 7), immediately absorbed by air on
lower surface of the rotary screen, the grey fabric on the joint of
two rotary screens shifted to surface of second rotary screen. The
dryed grey fabric through delivered to outside of the machine. The
fabric dryed uniformly, because it’s both side alternately dryed.
The principle of air circulation in the rotary screen dryer is
counter-current operation of exhaust gas circulation. Fresh air
indrafted from rear rotary screen and mixed with circulation air.
After heating, cycle use, parts of imbibed air enter into prior
rotary screen, continuous heating, then absorb water, the humidity
of air gradually increase, humid discharged to outer machine by the
action of centrifugal force, wet grey fabric meet with most humid
hot air, then the moisture regain of grey fabric gradually go down,
temperature escalates and meets fresh air with lower temperature in
the exit of rotary screen, grey fabric’s temperature drops.
