Description

SPECIFICATION Recovery system for cable scrap Conventional method for recovering copper from electric cable and wire scrap may utilize the direct method by burning scrap to separate the copper from the plastic insulated materials. However, such a direct burning of wire and cable may produce poisonous gases to cause air pollution and damage to health.
Conventional reclaiming system for wire and cable scrap may use fiuidized bed separating system which may separate the metal from plastic insulated materials by their different specific gravity. However, the separation will not be quite complete as the separated metal may still carry fluff or plastic scrap and the separated fluff may still contain metal scrap to reduce the recovery efficiency and minimize the economic value accordingly.
The present inventor has found the defects of conventional reclaiming methods and invented the present recovery system for electric wire and cable scrap.
According to the present invention there is provided a recovery system for cable scrap comprising a crushing means, a dust collector, a flat conveyor, a magnetic separator, a mixing screw conveyor, a cone type rotary separator and a settling separator wherein the magnetic separator may separate the steel material from the copper metal and the cone type rotary separator may separate the copper metal from plastic insulated materials and the settling separator may separate the piastics such as PVC from PE materials for more efficient and more complete recovery of the assorted materials from the scrap.
The present invention will be further described with reference to the accompanying drawings, in which: Figure 1 is a flow sheet diagram showing the recovery process of the present invention.
Figure 2 is a side-view sectional drawing taken from A-A direction of Fig. 1.
Figure 3 is a side-view sectional drawing taken from B-B direction of Fig. 1.
Figure 4 is a side-view sectional drawing taken from C-C direction of Fig. 1.
As shown in Fig. 1, the present invention comprises: a crushing means 1, a dust coilector 2, a flat conveyor 3, a magnetic separator 4, a mixing screw conveyor 5, a cone type rotary separator 6 and a settling separator 7.
Crushing means I comprises three sets of crusher 11, 1 2, 1 3 for crushing treatment of different sizes or specifications of scraps.
Ducts 24 are provided atop on crushers to suck the fluff or dust during crushing operation by means of a biower 21 to a dust collector 22 and the dust or fluff will then be accumulated in dust chamber 23 for final disposal.
Flat conveyor 3 is majorly a conveyor 31 positioned under crushing means 1 to take up the crushed materials through hoppers 14 each connected under each crusher. A magnetic separator 4 is formed above conveyor 31. Magnetic separator 4 comprises an inner magnetic conveying belt 41 having magnetic plates 411 paved thereon and driven by pulleys 44, 45; an outer non-magnetic conveying belt 42 overlapping on inner belt 41 but extending outwards to form a non-magnetic zone beyond magnetic belt 41 by another roller 43; a traverse conveying belt 46 positioned under roller 43 and a storage tank 47 provided under belt 46 as shown in Figs. 1 and 2.
Mixing screw conveyor 5 is provided to take up crushed materials from flat conveyor 3.
Conveyor 5 comprises a worm 51 provided in an inclined hollow cylinder 52 so as to convey the materials in lower container 53 upwards and unload the materials from upper hopper 54 which is connected with a charging trough 56 to charge the materials into cone type rotary separator 6. Two spray nozzles 32, 55 are respectively provided near the lower container 53 and charging trough 56 to spray water to wet the materials.
Cone type rotary separator 6 as shown in Figs. 1, 3 and 4 comprises: a truncated cone body 61 fitted on a fixed shaft 62 which is slopingiy fixed on two supporting frames 63, 64 with different heights, a receiving bucket 65 inserted within cone body 61, a driving motor 66, a hydraulic system 67 for adjusting the slope of cone body, a spray nozzle 68 inserted into cone body to spray water thereinto and a sloping trough 69 formed with several buffling plates 691 for further accumulating metal materials and for discharging water laden with plastic materials into settling separator 7. Several ribs 621 are provided to connect cone body 61 to shaft 62 and serve as an agitator for facilitating the separation of metal material from plastic material.Both ends of cone body 61 are respectively formed with two weirs of which the front weir 611 is formed as an annular extension from the larger perimeter 61 a and the rear weir 61 2 is formed as annular extension from the smaller perimeter 61 b on the rear side. The height of weir 61 2 should be higher than that of weir 611 to discharge plastic-laden water from weir 611.
At the rear end 61 b of cone body 61, a plurality of clutching fins 61 3 are formed along the inside wall of cone body 61 to catch the separated metal materials accumulated in the bottom portion of body 61 and unload into receiving bucket 65 which is connected with a sloping trough 651 to discharge metal materials into tank 652. The fin 61 3 may be drilled with fine perforation for water drainage therefrom. Cone body is tilted to the rear end with a slope.
Settling separator 7 consists of several set tling tanks having different heights. If for separating polyvinyl chloride (PVC) from polyethylene (PE), the highest tank 71 serves to settle the heaviest PVC granules; the second high tank 72 serves to settle the heavier PVC granules; the third high tank 73 settles the remaining PVC and the lowest tank 74 settles the lightest PE. A filter 741 is provided on tank 74 to drain out water and recover PE from tank 74. A boosting pump 731 is provided in tank 73 to supply water through conduit 732 to spray water at Nozzles 32, 55 and 68.
When using the present invention to recover copper from plastic materials, the different sized scraps are respectively filled into crushers 11, 12, 1 3 for crushing into granules of plastic materials and metal materials which are handled by conveyor 3 and in which the steel material St is attracted by magnetic conveyor 4 and recovered into tank 47. The copper granules are then charged into container 53 to be wetted by water from nozzle 32 and further mixed by screw conveyor 5.
The copper materials are then moistened by water from nozzle 55 and charged into cone type separator 6 where the plastic materials are laden in the upper water layer and discharged into sloping trough 69 to further recover few copper granules Cu accumulated on buffling plates 691. The plastic materials are separatedly settled into several tanks 71, 72, 73 and 74 with different heights with respect to different plastic specific gravity. The copper granules are pushed rearwards, caught by fins 613 and lifted upwards as rotating cone and then unloaded into bucket 65 and tank 652 to recover the copper material to completely separate from the plastic materials.
The slope of cone 61 and trough 69 may be optionally adjusted according to practical condition to increase the separation efficiency of the present invention.
The present invention has the following advantages superior to conventional reclaiming systems: 1. The cone type separator will efficiently separate the metal granules from plastic granules as continuous rotation and agitation of the granules will make the lighter plastic materials laden in upper layer of water to discharge from weir 611 and thus separate from copper materials.
2. A screw conveyor is provided to well mix the granules with water to reduce their surface tension suspending on water so as to enhance separation of plastic materials from metal materials.
The scope of protection is not limited by the terms of the claims which follow but extends to any equivalent thereof which achieves at least one of the advantages hereinbefore set forth.
