[57] ABSTRACT A one piece cyclone cone is provided with a flange for securing its upper end to the separation chamber of a cyclone. The cone is made of molded polyurethane plastic which is thickened at the wear areas adjacent the lower end. An apex member is seated in the lower end of the cone and is secured therein by a ring detachably secured to the lower end of the cone. The apex may be replaced while the cyclone is in operation by removing the ring to permit the apex to drop out of the bottom end following which the new apex is inserted into the bottom end and the ring replaced. The one piece structure of the cone provides uninterpreted flow so as to increase the efficiency of the cyclone.
5 Claims, 9 Drawing Figures PATEMEU EP 2M5 SHEET 2 [IF 2 ONE PIECE CYCLONE CONE BACKGROUND .OFTHE INVENTION I FIELD OF THE INVENTION The present invention relates to one piece cones for cyclones of the type for separating and/or classifying materials. I
SUMMARY OF THE INVENTION The present invention consists of a one piece polyruethane plastic cone having a flange on its upper edge which is secured to the chamber of a cyclone in depending relation thereto. The cone is thickened near its lower end in the area of greatest wear and has an apex inserted upwardly from. the bottom end into the lower end of the cone and secured therein by a detachable ring. A metallic retainer jacket surrounds the cone and has a flange underlying the flange of the cone and secured to the chamber by the same bolts securing the flange of the cone thereto.
The primary object of the invention is to provide a cyclone cone which is light in weight. provides an uninterpreted flow, and supports an apex in a manner which permits the apex to be removed and replaced during operation of the cyclone.
Other objects and advantages will become apparent in the following specification when considered in light of the attached drawings.

FIG. 8 is a vertical sectional view of one of the apices and FIG. 9 is a perspective view of the nut retaining ring with nuts attached thereto.
DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings in detail wherein like reference characters indicate like parts throughout the several figures the reference numeral 10 indicates gen erally a cyclone of the type with which the one piece cone generally indicated at 11 is used.
The cyclone 10 has a chamber 12 with an annular flange 13 integrally formed on the lower edge thereof. The chamber 13 is generally cylindrical and the flange 13 is generally circular. The cone 11 is formed of molded polyurethane plastic and has a thickened wall 14 adjacent its lower end having an internal annular recess 15 formed therein. The recess 15 has a cylindrical wall 16 extending downwardly therefrom and opening through the bottom of the cone 11.
A metallic nut retaining ring 17 has a plurality of nuts 18 welded thereto as can be seen in FIG. 9. The ring 17 is molded into the body of the cone 11 with the nuts 18 arranged along the bottom edge thereof to receive a plurality of bolts 19 which pass through a ring 20. An apex 21 of cylindrical outer conformation is seated in the recess 15 and the lower end thereof is engaged by the inner portion of the ring 20 to lock the apex 21 in the recess 15. The apex 21 slides freely in the recess 15 so as to be readily removed and replaced when the ring 20 is removed by removing the bolts 19.
A conical metal jacket 22 tightly encompasses the upper portion of the cone 1 l and has an annular flange 23 formed on its upper peripheral edge. The cone 1] has an annular flange 24 integrally formed on its upper edge for engagement and registry with the annular flange 13 of the chamber 12. A plurality of bolts 25 extend through the flanges 13, 24 and 23 to secure the jacket and cone to the chamber .12. The jacket 22 serves as a safety support for the cone 11 reinforcing the flange 24 so as to prevent it from being readily broken from the body of the cone 11.
The apex 21 is of conventional design having a conical opening 26 communicating with a cylindrical bore 27 opening completely through the apex. The apex 21 may be formed of polyurethane plastic, silicon carbide or any other highly effective wear resistant material.
In FIGS. 5 through 8 a modified form of the invention is illustrated for use with a cyclone generally indicated at 110. A cone generally indicated at 111 is formed of molded polyurethane material and provides an uninterpreted flow surface on its inner wall. The cone 111 is adapted for attachment to the chamber 112 of the cyclone which has a circular annular flange 113 formed on its lower end. The cone 111 is thickened at 114 in its area of greatest wear adjacent the lower end thereof. A recess 115 is formed internally of the lower end of the cone 111 and has a cylindrical wall 116 extending downwardly therefrom. The portion P surrounding the recess 115 is cylindrical in shape externally rather than conical as in the form of the invention described above. A nut retaining ring 17 having nuts 18 secured thereto is Cast into the plastic of the lower end of the cone 111 with the nuts 18 flush with the bottom edge thereof. Bolts 19 extend through a ring 20 and into the nuts 18 to secure the ring 20 to the lower end of the cone 111 and to thus secure an apex 21 in the recess 115.
The cone 111 is supported by a metallic jacket 22 having a flange 23 on its upper end. The cone 111 has a flange 124 on its upper end and bolts 125 extend through the flanges 113, 124 and 123 to secure the cone 111 and jacket 22 to the chamber 112.
The distinction between the form of the invention illustrated in FIG. 5 and and the form of the invention illustrated in FIG. 1 is that in smaller sizes of the cone it is necessary to form the lower end cylindrical to provide enough material in the wall to receive the ring 17 to support the nuts 18.
The apex 17 in FIG. 5 is removed and replaced in the lower end of the cone 111 in exactly the same manner as the apex 17 in the form of the invention illustrated in FIG. 1. v
The formation of the cone from polyurethane plastic reduces the weight of the cone to a fraction of that of prior art cones when made of metal or other cast material. The lightweight nature of applicants cone permits the cone to be handled much more easily and the cones can be stored by nest stacking in a warehouse. The uninterprete d flow vastly increases the efficiency of the cyclone and reduces the wear drastically as material flows through the cone.
Having thus described the preferred embodiments of the invention it should be understood that numerous structural modifications and adaptations may be resorted to without departing from the spirit of the invention.
What is claimed is:
l. A one piece cone element for a cyclone comprising an elongate generally conical polyurethane body having an annular flange integrally formed on the upper edge thereof, a generally cylindrical recess formed internally of the lower end of said cone and opening through the bottom thereof, an apex removeably seated in said recess and removeable through the lower end of said cone, and means detachably securing said apex in said recess comprising a first ring molded into said body adjacent the lower end thereof, a plurality of nuts secured to said first ring flush with the lower end of said body, a second ring positioned beneath said apex and said nuts, and a plurality of bolts extending through said second ring into said nuts for detachably
