Definitions

  • the present disclosure relates to a process and apparatus for the wet-treatment of loose fibrous material, particularly to a method and apparatus for scouring raw wool.
  • the apparatus of the present disclosure comprises a liquid container containing a treatment bath, means for introducing the fibrous stock into the liquid container, a first conveying element disposed in the liquid container at the inlet, said first conveying element being partially immersed in the treatment bath, a second conveying element disposed in the liquid container at the outlet and partially immersed in the treatment bath, said second conveying element being perforated to permit the treatment liquid to flow from the treatment bath to the inside of said second conveying element, means for returning the treatment liquid drawn into the perforated conveying element to the liquid container at the inlet, thereby producing in the liquid container a flow in the direction of material passage and means for removing the material being treated from the liquid container.
  • the present invention relates to a process and apparatus for the wet-treatment of loose fibrous material, particularly to a process and apparatus for scouring raw wool.
  • the apparatus of the present invention comprises a liquid
  • the well known raw wool scouring machines consist essentially of about five treatment bowls. The first one serves for wetting the wool and generally contains only sodium carbonate or another wetting agent, but no detergent. The following two to three bowls serve for scouring the wool. Here the dirtis washed out of the wool and in addition, the wool is degreased. The last bowl serves for rinsing purposes. Between the individual bowls squeezer means are arranged to dehydrate the woolwhen it is conveyed from one bowl to the next bowl.
  • An object of the present invention is to avoid the prior art disadvantages in the wet-treatment of loose fibrous stock.
  • Another object of the present invention is to provide an improved process and apparatus for the wet-treatment of loose fibrous stock, particularly for scouring raw wool wherein the wool is conveyed in the treatment bath in a gentle manner and providing at the same time a good dirt separation from the wool and a rapid sett ing of said dirt.
  • a further object of the present invention is to provide an improved process and apparatus for the wet-treatment of loose fibrous stock wherein optimum contact of the material being treated with the treatment liquid is ensured while at the same time producing a flow of the treatment liquid in the direction of material passage.
  • the treatment liquid flows through the discharge element from the outside to the inside thereof and the liquid which is discharged. by the discharge element is returned to the inlet of the liquid container.
  • the liquid which is discharged at the end of the liquid container is returned to the inlet of said container.
  • a flow from the inlet to the discharge end of said container is. produced in the treatment zone which enables the loose fibrous ma-. terial, particularly raw wool, to float freely in the treatment liquid.
  • the dirt particles adhering to the wool are soaked and can detach from the wool and settle down into the dirt sediment zone Since. there is no liquid motion in the dirt sedimentfzone, settling of the dirtat the lbOttom of the container is readily facilitated.
  • the scouring effect is particularly good at the discharge element since at this point the fibrous material is intensely penetrated. by the treatment liquid. Because of the liquid penetration from the outside to the inside of the discharge element, a uniform fleece is formed at the discharge element thereby permitting a. uniform squeezing of the material, for example wool.
  • a sieve roller 22 is provided as a discharge element which is connected with the collecting container 14 by means of a conduit so that in this case also the treatment liquid flows through the sieve roller 22 due to the differential liquid level.
  • a suction roller can also be used in which one or several pumps are arranged for producing the suction draft.
  • the bottom roller 19 of the squeeze rollers 15 is again perforated and used as a discharge element. In this design no installations whatsoever are required in the roller 19.
  • the liquid flows through the roller 19 solely due to the level difference between the treatment liquid in the treatment zone 3 and the treatment liquid in the collecting container 14.
  • a pump 23 is correlated which returns the liquid to the inlet of the liquid container through a conduit 24. According to the capacity of the pump 23 the level difference between collecting container 14 and treatment zone 3 and thus also the liquid quantity which fiows through the roller 19 can be regulated.
  • An apparatus for the wet-treatment of loose fibrous stock which comprises a liquid container containing a treatment bath, means for introducing the fibrous stock into the liquid container, a suction drum as a first conveying element disposed in the liquid container at the inlet, said first conveying element being partially immersed in the treatment bath, a second conveying element disposed in the liquid container at the outlet and partially immersed in the treatment bath, said second conveying element being perforated to permit the treatment liquid to flow from the treatment bath to the inside of said second conveying element, means for returning the treatment liquid drawn into the perforated conveying element to the liquid container at the inlet, thereby producing in the liquid container a flow in the direction of material passage and means for removing the fibrous stock from the liquid container.
  • the second conveying element comprises a perforated roller which acts as a bottom roller and cooperates with an upper roller to form a pair of squeeze rollers as the discharge element, said perforated roller containing a baflie means disposed in said rollers below the liquid level to interrupt the flow from the container into the roller, said bafile means supporting a swivel sheet which, by its position, varies the level difference between the liquid in the container and the liquid in the roller thereby controlling the quantity of liquid flowing through the roller.
  • the second conveying element comprises a sieve roller disposed in front of outlet squeeze roller means, said second conveying element communicating with a collecting container outside of the liquid container by conduit means.
  • a suction box communicates with the interior of the conveyor belt below the surface of the treatment liquid and a collecting container is disposed below the squeeze roller means outside of the liquid container, said suction box being connected to the collecting container by conduit means.
  • the second conveying element comprises a perforated roller which acts as a bottom roller and cooperates with an upper roller to form a pair of squeeze rollers as the discharge element, said perforated roller being associated with a collecting container which is provided with a pump means which conveys the treatment liquid through conduit means back to the inlet of the liquid container.
  • An apparatus for the wet-treatment of loose fibrous stock which comprises a liquid container containing a treatment bath, a perforated intermediate bottom means which subdivides the liquid container into an upper trough-like treatment zone and a lower dirt sediment zone, inlet means for introducing the material to be treated into the liquid container, a paddle roller means disposed in the liquid container at the inlet, said paddle roller means.
  • a perforated conveyor belt disposed at the outlet of the liquid container means, a substantial portion of the conveyor belt obliquely extending out of the treatment bath in the direction of material passage, thereby providing a conveying surface above the level of the treatment liquid, a suction box communicating with the interior surface of the conveyor belt below the surface of the treatment liquid, a collecting tank disposed outside of the liquid container, conduit means connecting the suction box to the collecting container, means for conveying the treatment liquid from the collecting container to the inlet of the liquid container and outlet squeeze roller means disposed above the collecting tank for removing the material from the liquid container.
  • An apparatus for the wet-treatment of loose fibrous stock which comprises a liquid container containing a treatment bath, a perforated intermediate bottom means which subdivides the liquid container into an upper trough-like treatment zone and a loWer dirt sediment zone, inlet means for introducing the material to be treated into the liquid container, a perforated conveyor belt disposed in the liquid container at the inlet, a substantial portion of the conveyor belt obliquely extending into the treatment bath in the direction of material passage thereby providing a conveying surface beneath the level of the treatment liquid, a perforated roller disposed in the conveyor belt at its discharge end, said roller provided with a suction means which draws the treatment liquid through the conveyor belt, into one side of the discharge roller and discharges it out the other side of said roller through he discharge end of the conveyor belt, a perforated roller isposed at the outlet of the liquid container, said perfoated roller acting as a bottom roller and cooperating with an upper roller to form a pair of squeeze rollers as he discharge element, said perforated
  • liquid convainer has an oblique bottom.
  • a method for the wet-treatment of loose fibrous xtock which comprises introducing said material into a iquid bath containing a treatment liquid, conveying the naterial beneath the surface of the treatment liquid on the surface of a conveying element, floating the material For a distance on the surface of the treatment liquid, renoving the material from the treatment bath on the sur- Face of a conveying element, removing a portion of the :reatment liquid from the material and from the treatnent bath by means of a suction draft and returning said treatment liquid to the inlet of the treatment bath thereby producing a liquid flow in the direction of material passage.
