Fig.9. The air gap system is 5 mm and the distance to the saw tooth is 85 mm
The air spray system showed a result of 33 meters / second when the distance to the slot 5
mm saw was 85 mm.
Modeling of air blowing chamber and fiber receiving chamber
We determine the surface of the inlet pipe b=250mm x h=250mm = 25cm x 25cm
S= 25x25=625cm

We determine the surface of the exit slot b=1500mm x h=5mm =150cm x 0.5cm
S=150cm x 0.5cm= 75cm

We are completely satisfied with the characteristics of the VTS-10 fan, since the air blowing
system and the intake system are two sets in our new construction gin machine.The
air spray
system showed a result of 53 meters/second at a distance of 45 mm to the notch 5 mm saw. The
air-push system showed 49 meters/second at a distance of 65 mm to the notch 5 mm saw. The
air spray system showed a result of 33 meters / second when the distance to the slot 5 mm saw
was 85 mm. We extended the intake pipe from the fan to allow air to flow through the air intake
slot at a speed of 63 meters per second, and we achieved a high pressure build-up in the air intake
system. In
our new construction machine, the air blowing system collects
the air flow coming
from the fan through a rectangular tube of b=250mm x h=250mm and collects it in the whole air
blowing system through a slot with a size of S=150cm x 0.5cm= 75cm2. sends The air flow comes
out of the slot of the air blowing system at a speed of 63 meters per second and removes the
fiber from the saw teeth and transfers it to the air intake system.
In this case, we take the
diameter of the guide pipe as 105 mm.
