- Figure 8 is a schematic drawing showing an eight embodiment of the system according to the present invention.
- Figures 9 to 1 1 show contaminated wool before, during and after being subject to treatment in the system according to the present invention.
- FIG. 1 there is shown a system 10 for treating a mixture 12 of wool fibres 14 and polymer fibres 16 which represent contamination of the wool fibres 14.
- the system 10 has a treatment station 18 which in this case has a hot air blower 20 for blowing hot air at about 180°C onto the mixture 12.
- the mixture 12 as can be seen is guided into the treatment station 18 by guiding means in the form of a perforated conveyor 22 movably controlled by spaced rollers 24.
- the rollers 24 are controlled so that the mixture 12 is exposed to heat in the treatment 18 for about 3 seconds.
- Figure 1 shows that the treated contaminating fibres 1 6 change shape and a fine reticulating comb 26 separates the treated fibres 16 from the wool fibres 14. Clean wool fibre 28 is thereby obtained following combing.
- the mixture 12 is guided into the treatment station 18 and then guided through the station 18 under tension by rollers 30.
- FIG 3 shows an embodiment of the system 10 which is similar to the Figure 2 embodiment except for the addition of a conveyor 24.
- the embodiment of the system 10 shown in Figure 4 has a further conveyor 25.
- the embodiments shown in Figures 1 to 4 have hot air applied from one side of the mixture 12.
- the treatment station 18 has air openings 32 positioned just downstream of the rollers 30 at the inlet end of the station 18. The openings 32 allow hot air to be applied to either sides of the mixture 12. In this manner contaminating plastic materials 16 on or near both surfaces of the mixture 12 are equally treated.
- Figure 6 shows an embodiment of the system 10 which guides the wool mixture 12 from the doffer 34 of the carding stage into the treatment station 18 for heat treatment before being collected in the coil head 36.
- the treatment station 18 shown in Figure 6 has a serpentine path which helps to reduce the length of the station 18.
- FIG. 6A Another form of the serpentine path is shown in Figure 6A.
- the treatment station 18 has feed rollers 30 at inlet and outlet thereof.
- the feed rollers 30 at the inlet guide the mixture 12 into the station 18.
- various rollers and conveyors arranged as shown move the mixture 12 in a three loop serpentine path before being guided by the feed rollers 30 at the outlet out of the station 18.
- FIG. 6B there is shown a further form of the serpentine path.
- a pulley arrangement is used to train the mixture 12 along a serpentine path.
- the form of the serpentine path for the mixture 12 in Figure 6C is guided by a series a rollers arranged as shown.
- the system 10 is incorporated into the carding stage of wool processing.
- the treatment station has an oven 38 shaped to fit over the lower part of the doffer 40.
- the wall of the oven which embraces the doffer 40 is spaced from the outer perimeter of the doffer 40 so that the mixture 12 can enter the space in which it is subject to heat treatment.
- the mixture 12 is guided by the doffer 40 to the doffer comb 42 which removes the mixture 12 from the doffer 40.
- Col lander rollers 44 guide the mixture 12 out of the carding stage and the station 18.
- FIG 8 shows an embodiment of the system 10 according to the present invention in which both heated air and a guide air stream are reused.
- the feed rollers 30 have a hollow body with perforations, and a baffle plate 52 separating the perforations so that half of the perforations are exposed to the guide air stream 54 shown in solid arrows and half are exposed to heated air 56 shown in hollow arrows.
- a conduit 58 provides a bypass path for the air stream 52 through said perforations of the rollers 30 at the inlet of said treatment station 18 to flow to said rollers 30 at the outlet of the station 18.
- the air stream 54 then flows through perforations of the rollers at said outlet to guide treated mixture 12 to a subsequent process station (not shown).
- the heated air 56 is recirculated by a pump 60 in a conduit 62 which joins the rollers 30 at the inlet and the outlet.
- the perforations and the baffle plate 52 in the rollers 30 allow substantially all of the guide air stream to bypass the station 18 and to be reused for guiding treated mixture 12. The same also allow substantially all of the heated air 56 to recirculate in and out of the station 18 so that heating costs are minimised.
- Figure 9 shows a sample of wool 14 contaminated with polymer fibres 16.
- the fibres 16 shrunk following heat treatment at the station 18. They become shorter but with denser mass and larger cross-section.
- Figure 1 1 the treated fibres 16 have been removed in a combing processing step.
