Abstract
A helical distributing chute conveyor for a receptacle for transferring loose varied fragile chemical and pharmaceutical products, particularly of the granular or pulverulent type. This chute conveyor, placed in a receptacle, comprises helical chute paths developed about a vertical axis; each chute path, whom cross section is straight, is inclined transversely towards the vertical axis, the angle of inclination of the chute path being calculated such that, whatever their size, the particles of material transported deviate towards the vertical axis when the centrifugal force which originally keeps them on the chute path cancels out or drops below a critical value.
Claims19
A helical distributing chute conveyor for a receptacle for transferring loose varied fragile pharmaceutical or chemical products, this chute conveyor comprising at least one helical chute path developing about a vertical axis, said chute path having a cross-section and a transverse angle of inclination, wherein
- a central volume of the chute conveyor is hollowed out in the form of a well;
- each chute path is continuous and has substantially constant pitch;
- and
- each chute path forms a broad plateau, the cross section of which is substantially straight, inclined transversely towards the axis, the transverse angle of inclination of the chute path being such that transferred products, given at the upper part of each helicoid sufficient speed for centrifugal force to keep them along the corresponding chute path, deviate towards the axis when the centrifugal force which holds them on the chute path cancels out or drops below a critical value.
