Description

A SEPARATOR
Technical Field
The present invention relates to separator iron from non-ferrous material, and more particularly but not exclusively to separate wire and mesh used in the construction of tyres from rubber and other material used in the construction of tyres.
Background of the Invention
The disposal of tyres presents an environmental issue. By far the best proposal is to recycle the materials from which tyres are constructed.
It is generally accepted that to recycle tyres the tyres need to be reduced to particles by means of shredding and/or milling, or for that matter by any means. Once this has occurred the rubber can be separated from wire and/or mesh employed in the construction of the tyre.
Mechanisms employed to separate the wire and mesh (steel) generally include conveyors having a magnetic length. These mechanisms are not efficient both in respect of flow rated material processed, and the accuracy of sorting the wire and/or mesh from the other substances such as cloth and rubber.
Object of the Invention
It is the object of the present invention to overcome or substantially ameliorate at least one of the above disadvantages.
Summary of the Invention
There is disclosed herein a separator to separate iron from a mixture containing iron and non-ferrous material, said separator including: a surface extending longitudinally and angularly about a longitudinal axis so as to have a circular transverse cross-section; a magnet located in said chamber and extending longitudinally relative to said axis and angularly relative to said axis so as to be located near said surface to attract the iron to said surface, said magnet having a longitudinal end extremity and longitudinally extending extremities so that said magnet does not extend angularly entirely about said axis near said surface; an auger member located adjacent said surface so as to extend longitudinally of and angularly about said axis so as to provide a plurality convolutions, convolutions extending away from said surface outward relatively to said axis; and a drive mechanism to rotate the auger member about said axis repeatedly through
360° in a predetermined auger direction so that upon said mixture being delivered to adjacent said surface, the iron is attracted to said surface and is conveyed longitudinally relative to said axis by said auger member to beyond said end extremity so that the iron is delivered from said separator.
Preferably, said surface is provided by a drum, with said auger being fixed to said drum, and with said drive mechanism being drivingly attached to said drum to cause rotation of said drum and said auger member about said axis.
Preferably, said surface is of a cylindrical configuration. Preferably, said magnet extends angularly about said axis for an angle of between 90° and 180° relative to a generally vertical axis passing through said longitudinal axis.
Preferably, said separator further includes a plurality of apertures in said surface, and means to deliver air under pressure to said apertures to aid in removing non-ferrous material from said surface.
Preferably, said drum has a longitudinal length, and said magnet extends longitudinally a magnet length less than the longitudinal length of said drum.
Preferably, the magnet is stationary.
There is further disclosed herein in combination, the above separator and a conveyor, said conveyor being located below said separator so that upon said mixture being conveyed to adjacent said surface by said conveyor, the iron is attracted to said surface from the conveyor.
Brief Description of the Drawings
A preferred form of the present invention will now be described by way of example with reference to the accompanying drawings wherein:
Figure 1 is a schematic sectioned side elevation of a separator; and
Figure 2 is a schematic end elevation of a portion of the separator of Figure 1.
Detailed Description of the Preferred Embodiment
In the accompanying drawings there is schematically depicted a separator 10. The separator 10 receives a mixture including iron and non-ferrous material, such as tyres that are reduced to particles. For example, the mixture may include steel wire and/or mesh together with non-ferrous materials such as rubber and cloth. The separator 10 includes a drum 11 having a longitudinal axis 12. The drum 11 has a radially outer surface 13 that is circular in transverse cross-section. In this embodiment, the surface 13 and drum 11 are cylindrical in configuration, however other configurations are contemplated, such as a frusto-conical configuration. The surface 13 extends longitudinally of and angularly about the axis 12 so as to surround a chamber 14.
Fixed to the drum 11 is an auger member 15 that extends longitudinally of and angularly about the axis 12 so as to provide a plurality of convolutions 16, each convolution 16 extending from the surface 13 away from the axis 12. Also, as best seen in Figure 1, each convolution is inclined to the surface 13 by an acute angle 17.
The drum 11 has end walls 18 that generally close the chamber 14.
Extending longitudinally into the chamber 14 is a stationary shaft 19. Mounted on the shaft 19 is a magnet 20 that extends angularly about and longitudinally relative to the shaft 12 so as to have a longitudinal end extremity 21 and longitudinally extending extremities 22. Preferably, the magnet 20 extends about the axis 12 by an angle 23, the angle 23 extending from about 90° to about 180°, preferably 135° to 180°, from the vertical transverse axis 24 in the direction indicated by the arrow 27. Accordingly when the axis 12 is extending generally horizontal, the magnet 20 is located in the lower portion of the chamber 14, that is generally below the axis 12, The drum 11 is supported on the shaft 19 by bearings 24 so that the drum 11, with the auger member 15 fixed thereto, can rotate about the axis 12.
Attached to one of the end walls 18 is a drive shaft 26 that is driven by means of a pulley 25, in turn driven by an electric motor not illustrated. Accordingly upon the shaft 26 being driven, the drum 11 is caused to rotate through 360° repeatedly about the axis 12. More particularly the drum 11 is rotated in the angular direction 27. In that regard it should be appreciated Figure 2 is a cross-section of the drum 11 along the line 2-2, and viewed in the direction 2.
The shaft 26 is supported by bearings 28.
Located below but near the surface 13 is a delivery conveyor 29 upon which a mixture containing iron moves so as to move past the surface 13. Iron being conveyed by the conveyor 29 is attracted to the surface 13. At least a significant portion of the non- ferrous material is then conveyed by the conveyor 29 to a collection facility. Material deposited on the surface 13 is caused to move in the direction of the arrow 30, by interaction between the convolutions 16 and the magnet 20. As material containing iron passes in the direction of the arrow 27 adjacent the magnet 20, it is conveyed upwardly until it reaches the upper longitudinally extending extremity 22, at which time it will then "tumble" down the convolutions 16 until it reaches the end extremity 21 wherefrom it leaves the drum 11 and is delivered to a chute 31. The chute 31 delivers the material to a conveyor 32.
Preferably, the drum 11 has passages providing a plurality of apertures 33 in the surface 13, with the chamber 14 receiving air under pressure through the shaft 19. The shaft 19 has apertures 34 via which the air is delivered to the chamber 14. Air leaving the apertures 33 aids in removing non-ferrous material from the surface 13, as well as ferrous material on the surface 13 beyond the end extremity 21.
