Information of screw conveyor
Screw conveyor is a kind of machinery that uses motor to drive
screw rotation and push materials to achieve the purpose of
conveying. It can be transported horizontally, obliquely or
vertically. It has the advantages of simple structure, small
cross-sectional area, good sealing, convenient operation, easy
maintenance and closed transportation. Screw conveyor can be
divided into shaft screw conveyor and shaftless screw conveyor in
conveying form, and U-type screw conveyor and tubular screw
conveyor in appearance. The shaft screw conveyor is suitable for
cohesionless dry powder materials and small particle materials
(such as cement, fly ash, lime, grain, etc.), while the shaftless
screw conveyor is suitable for viscous and easy winding materials.
(for example: sludge, biomass, garbage, etc.) the working principle
of the screw conveyor is that the rotating spiral blade moves the
material and carries out the screw conveyor conveying. The force
that makes the material not rotate with the screw conveyor blade is
the material weight and the friction resistance of the screw
conveyor shell to the material. For spiral blades welded on the
rotating shaft of screw conveyor, the surface types of blades
include solid surface, belt surface, blade surface, etc. A thrust
bearing is provided at the end of the screw shaft of the screw
conveyor in the direction of material movement to give the axial
reaction force to the screw along with the material. When the
length of the machine is long, the middle hanging bearing should be
added.
Characteristics of screw conveyor.
The screw conveyor is a kind of continuous conveying equipment
without flexible traction, which uses the rotating screw to move
the conveyed material along the fixed casing. It is as if the
unrotatable nut is held and translated along the screw. The force
that keeps the material from rotating with the screw is the gravity
of the material and the friction against the shell.
The advantages of the screw conveyor are: simple structure,
convenient maintenance, small size of the cross section, can enter
and leave materials at any position in the length direction, and
can use the cover of the tight closed housing to achieve a better
sealing effect.
Therefore, screw conveyor is widely used in various industrial
sectors to transport a variety of powdered, granular and small
materials, such as coal ash, cement, sand, coal, cereals and so on;
it is not easy to transport viscous caking materials which are easy
to deteriorate.
