Definitions

  • the invention relates to a device as defined in the preamble of the first claim.
  • a device of this type is known from DE 23 57 055 A1.
  • FR 1 541 194 A1 can also be mentioned in this context, according to which the liquid discharged from the sieve drum is also added at the beginning of the bath, but into a swimming section adjoining there.
  • Raw wool washing machines of this type have proven themselves many times in practice. Your advantage lies in the gentle treatment of the fiber material with very good cleaning results. These good treatment results are achieved by the fact that the liquid contained on the surface of the filter drum is held immovable by the liquid contained in the detergent and then runs through a swimming section without any influence from mechanical washing or conveying devices, in the area of which the dirt particles loosened during the flow automatically hit the bottom the washing machines can fall down.
  • the invention has for its object to continue to develop a device of the type mentioned in such a way that it has a self-cleaning effect.
  • a continuous washing treatment should be possible without the need for cleaning operations which interrupt the operation.
  • the invention provides the following constructive measures on the previously known device, namely that the liquid circulated in the bath housing can only be supplied to the treatment room via the channel at the beginning of the bath housing, and that an outflow nose of the perforated bottom assigned to the pair of press rollers is below the liquid level , but ends higher than the lower press nip of the pair of press rolls. It is essential in the idea according to the invention that the liquid flow generated by supplying the liquid at the inlet of the respective bath is not disturbed by the cleaning process along the entire bath. This is possible if the liquid circulated in the bath is only fed in at the inlet through the channel and discharged again at the end of the bath.
  • the liquid parallel flow to the fleece is only possible if a larger amount of liquid runs off at the end of the bath. For this reason, the outflow nose at the end of the treatment room was arranged considerably lower than the liquid level.
  • the wool fleece cleaned in the bath then also flows off with the flowing liquid and is fed to the pair of press rolls by this flow without stagnation.
  • the press nip of the pair of press rolls is then arranged lower than the outflow nose.
  • this is done according to the above-mentioned laid-open publications, in which the press nip is always arranged at the level of the liquid within the bath in order to have to squeeze out as little liquid as possible in the press and also as little wool fibers in front of the pair of squeeze rolls due to flowing liquid to lose.
  • the device according to the invention accepts this disadvantage. However, it avoids fiber loss, because these fibers flowing out of the nonwoven dressing and the squeezing liquid are returned to the bath through a pipeline the beginning of which are pumped.
  • washout nose which not only has to ensure the continuous removal of the incoming wool fleece, but also the even removal of the accompanying liquid.
  • the raw wool washing device consists of several bath housings 1 which hold the liquid up to a level 2, in each of which three sieve drums 3, 4 and 5 are rotatably mounted.
  • the treatment room 6 in this bathroom housing 1 is separated from the contaminant removal room 7 by a perforated floor 8.
  • This base is adapted to the curvature of the sieve drums 3-5 and is arranged at a distance from the sieve drums 3-5 to form the treatment room 6.
  • the contaminant discharge space 7 is formed by a funnel 11, on the walls of which the contaminants precipitated from the fleece continuously slide towards the discharge opening 12.
  • the liquid which has penetrated into the interior of the sieve drum through the perforation of the respective sieve drum automatically flows out through openings 13 at the ends of the sieve drum into longitudinal channels 14, 15 flanged on the outside on the end face.
  • the liquid which has flowed into the channel 14 passes through a pipe 16 into the channel 15, from where the total liquid is pumped with the aid of the pump 17 into the channel 18 which extends across the working width at the beginning of the bath housing 1 and from there via an inflow nose 19 flows into the treatment room 6. From there, this liquid, which is supplied again in the circuit, flows on the one hand through the newly arriving fleece 10 and then through the first screening drum 3, but also because of the excess liquid flowing parallel to the fleece 10 according to arrow 20.
  • the construction of the outlet of each bath can be seen in detail in FIG. 4.
  • the outflow nose 22 is arranged lower than the liquid level 2 or the axis of rotation of the screen drum 5. This has the consequence that a large amount of the treatment liquid flows out to the press roll nip 23 together with the wool fleece 10 to be squeezed, but it is without disadvantage for the wool . On the contrary, the wool is continuously transported away.
  • the outflow nose 22 of the perforated base 8 is arranged at a distance from the press nip 23.
  • the distance between the lower press roll 24 and the outflow nose 22 is bridged by an additional perforated base plate 25.
  • the bottom plate 25 is convexly curved upwards. Due to this figuration of the bottom plate 25, the fleece 10 to be squeezed is quickly removed.
  • the outlet end 26 of the bottom plate 25 is not assigned to the nip 23, but rather to the lower press roller 24, so that a jam of wool fibers cannot occur.
  • the bottom plate 25 in the bath housing 1 is arranged so that it can be pivoted back and forth to the washout nose 22.
