Embodiment two：
The working process and principle of the utility model are explained：
The tubular outer tube diameter of circular cone is small in the big lower part in top, is often fixed in rack, is considered as inactive state；Inside spin
（Same is in the small shape in the big lower part in top）Then rotated by direction as shown.When spiral rotating, due to helicoid push act on
And the double action of the frictional force of material and helicoid, material will follow spiral conveying tube to rotate together, when helical axis 7
When rotating speed improves, the rotating speed of material also improves therewith.When rotating speed reaches certain value, centrifugal force that material is subject to will overcome spiral shell
Vane face produce frictional force, material radially slides to outer tube wall, since outer tube wall is tapered, therefore material be subject to tube wall to
The component of upper effect is more than 0, and the component that isometrical outer tube wall acts on upwards is equal to 0.
And as rotating speed further improves, due to the effect of centrifugal force, material is crushed on outer tube wall, and material is subject to pipe
The component that wall acts on upwards and angle of taper are proportional, proportional with the pressure suffered by material.When outer tube wall taper is certain
When, the more big upward component of pressure is also bigger, on the one hand the frictional force that outer tube wall produces material at this time prevents material along pipe
Wall glides（Grab wall phenomenon）, material is on the other hand driven along helicoid upward sliding（Drive phenomenon）.
It is spiral on some rotating speed（In the case that structural parameters are fixed）, material neither can glide nor move up, this turn
Speed is that vertical spin delivery pipe produces the theoretic lowest limit rotating speed of improving material.
When outer tube tubular using circular cone, since inner cone tube wall provides material one upward component, so in structure
And other specification it is identical in the case of conical pipe it is low compared with equal pipe lowest limit rotating speed, that is to say, that obtain same unloading effect
The power of rate is small.
