DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1) Field of the Invention
Generally, the filing of receptacles with solid particles (granular solids) is accomplished by transfer of the solid particles by means of a funnel and/or a cone either manually or mechanically or by pneumatic transference.
2) Background Art
As a general rule, it is of utmost interest to introduce the maximum amount of product into a given space, as much in order to reduce the cost of storage as well as for other specific reasons, such as, for example, to standardize storage or reduce the volume of air or gas in the container. The object of the present invention is to provide an apparatus which makes it possible to achieve an increase in the quantity of solid introduced into a certain volume.
Everyday storage situations relate to cereals (in silos), food products intended for consumption or for livestock, agro-alimentary products, fertilizers, chemicals, granulated plastics, pharmaceutical and/or cosmetic products, and many other divided solid material (grains or tablets or extruded granulate material, pills, agglomerates, crushed materials, etc.).
Another field of application includes receptacles or chemical reactors intended to be filled with solid particles: catalysts, adsorbents, reagents, packings, sundry fillings. In this case, it is almost always advantageous to place the maximum amount of solid product inside the reactor in order to enhance the activity thereof per unit volume and therefore to improve the efficiency and effective service life (cycle time or working life).
A suitable method resides in using the apparatus described in French Patent No. 2431449. Other apparatuses have already been described in the prior art, particularly the apparatus described in Patent DE-A-2 703 329.
SUMMARY OF THE INVENTION
An apparatus for filling a receptacle with a divided product or divided solids comprises a hopper and a motor fixed to the hopper. A substantially vertical shaft is driven by the motor and a dispersion head is connected to the shaft for rotation by the motor. The dispersion head comprises at least three substantially circular plates arranged coaxially and being substantially parallel. The plates are disposed one below another with the radius of each plate steadily decreasing from the top plate to the bottom plate. A series of at least two and preferably at least three substantially concentric tubes of cylindrical form are stacked coaxially from a highest to a lowest, and are demountable and adapted for sliding movement.
BRIEF DESCRIPTION OF THE DRAWINGS
Various other objects, features and attendant advantages of the present invention will be more fully appreciated as the same becomes better understood when considered in conjunction with the accompanying drawings, in which like reference characters designate the same or similar parts throughout the several views, and wherein:
FIG. 1 is a side elevation of a hopper configured in accordance with the principles of the instant invention;
FIG. 2 is a perspective view of a plate utilized with the hopper of FIG. 1;
FIG. 3 is a planar view of a plate illustrating various configurations;
FIG. 4 is a side elevation showing the hopper of FIG. 1 in combination with a receptacle;
FIG. 5 is an exploded perspective view of an embodiment with plates of a selected configuration; and
FIG. 6 is a top view of the plates of FIG. 5 superimposed.
DETAILED DESCRIPTION
FIG. 1 illustrates a hopper configured in accordance with the invention. The apparatus consists of a fixed feed hopper (1), preferably having in its center a pneumatic motor (2) possibly supplied with gas (air, for example, for its operation). The motor (2) is attached to the hopper by a flange B and A is the hopper. The motor (2) drives a shaft (3) which produces rotation of a dispersion head C to which the shaft is attached. This dispersion head C comprises at least two plates and preferably at least three or four plates. FIG. I shows four plates (4), (5), (6) and (7) which are generally rigid with one another, for example via a support, fo
