Definitions

  • the invention relates to a device for the purification of fiber material with a cleaning roller and a cleaner housing having cleaner and arranged above the cleaner Kondenser.
  • the now formed on the surface (outer circumference) of the screen drum fiber mat is transferred by the rotational movement of the screen drum to a rotating feed roller (fan roller), which is provided with outwardly projecting scrapers, or with subjects, on which the fiber drum located on the screen drum is removed.
  • the removed fiber material is delivered by the rotational movement of the feed roller to a subsequent channel, which has the shape of a funnel and opens into an inlet, or inlet connection of a subsequent cleaner.
  • the cleaner is provided with a cleaning roller, via which the fiber material is transported spirally in the direction of the longitudinal axis of the cleaning roller to a discharge opening.
  • the spiral transport of the fiber material is effected by appropriately mounted in the cleaner guide elements. During the transport of the fiber material through the cleaner this happens several times below the cleaning roller mounted grate, over which by the influence of, mounted on the cleaning roller pins and under the action of centrifugal impurities from the fiber material are deposited.
  • the invention is now based on the object to propose a device for the purification of fiber material, which allows a continuous cleaning of fiber material with high productivity with a trouble-free transfer of the fiber material from the condenser in the cleaner.
  • a novel device for cleaning of fiber material with a cleaning roller and a cleaner housing having cleaner and a cleaner arranged above the condenser and a pneumatic feed of the fiber material with transport air to the condenser proposed.
  • the condenser has an air-permeable, in a screen drum housing rotatably mounted screen drum and a rotatably mounted in a Lucaswalzengephase feed roller, each having a longitudinal axis.
  • the feed roller is arranged between the screen drum and the cleaning roller and the fiber material is guided with the transport air directed onto an outer surface of the screen drum.
  • the feed roller has on its circumference in the direction of the longitudinal axis arranged radially projecting ribs with outer ends, which form an enveloping circle. Between the outer surface of the screen drum and the enveloping circle of the feed roller is provided a distance of less than 1.0 mm. A distance between the enveloping circle of the feed roller and a surface of the cleaning roller is 30 mm to 250 mm.
  • the distance between the outer ends of the ribs of the feed roller and the surface of the cleaning roller is limited to 30 mm to 250 mm, advantageously the feed roller housing in the region of an inlet opening of the cleaner is connected to the cleaner housing. This ensures a uniform and trouble-free fiber flow to the cleaner following the feed roller.
  • the condenser is thus placed directly on the cleaner housing, which also leads to a structurally simpler solution.
  • a speed of the feed roller is 300 to 500 revolutions per minute and the screen drum 100 to 200 revolutions per minute. This ensures a gentle treatment of the fiber material and a safe stripping of the fiber material from the sieve drum. Due to the generally larger diameter of the screen drum relative to the enveloping circle diameter of the feed roller results in a nearly equal circumferential speed between the surface of the screen drum and the outer ends of the ribs of the feed roller, whereby the stripping process of the fiber material is ensured by the screen drum, advantageously the distance between the enveloping circle of the feed roller and the outer surface of the screen drum is zero and touching the enveloping circle of the feed roller and the outer surface of the screen drum.
  • a direction of rotation of the feed roller and the screen drum are opposite, whereby the stripping process is further improved.
  • the axes of the screen drum and the feed roller are arranged parallel to the axis of the cleaning roller. This ensures a continuous tangential feeding of the fiber flow to the cleaning roller.
  • the feed roller In order to adapt the width of the stripped Fasergutstromes of the screen drum to the subsequent inlet opening of the inlet of the cleaner preferably has the feed roller on a length which corresponds to the length of the inlet opening of the cleaner. Thus, no further means are necessary to adapt the output of the feed roller Fasergutstrom to the width of the inlet opening of the cleaner. Accordingly, it is advantageous if a length of the feed roller corresponds to a length of the screen drum.
  • FIG. 1 shows a schematic representation of an embodiment of a cleaning device according to the prior art, which comprises a condenser 4 and arranged below the condenser 4 cleaner 1 with a cleaning housing 3 rotatably mounted in a cleaning roller 3.
  • the condenser 4 has a sieve drum 5 mounted rotatably about a longitudinal axis 7 in a sieve drum housing 14, which is fed with fiber material 2 via a channel 17, and one about a longitudinal axis 8 rotatably mounted in a feed roller housing 18 feed roller 6 (also called fan roller) on.
  • the fiber material 2 of the screen drum 5 is supplied.
  • a negative pressure is applied by a vacuum source 29.
  • the supplied fiber material 2 is sucked onto the surface 10 of the screen drum 5 and separated by the air-permeable surface 10 of the screen drum 5 of the transport air 9, which passes through the openings of the screen drum 5 and is discharged via the vacuum source 29.
  • a fibrous nonwoven forms on the circumference 10 of the screen drum 5, which is transferred by the, indicated by an arrow direction of rotation of the screen drum 5 to a passage opening 28 in the screen drum housing 14.
  • the feed roller 6 is arranged below the screen drum 5 and the feed roller housing 18 directly adjoins the screen drum housing 14.
  • the direction of rotation of the feed roller 6 corresponds to the direction of rotation of the screen drum 5.
  • the surface of the feed roller 6 and the surface 10 of the screen drum 5 move in the opposite direction.
  • the formed on the surface 10 of the screen drum 5 Fasergutvlies is stripped by the rotational movement of the feed roller 6 and attached to the circumference of the feed roller 6, outwardly projecting ribs 11 and discharged by gravity down into a conveyor channel 20.
  • the delivery channel 20 is funnel-shaped (see Fig.2 of the CH 695 154 A5 ), so that the output of the feed roller 6 Fasergutmasse is summarized on the cross section of a subsequent input port 21 of the cleaner 1.
  • the fiber material is fed tangentially to the cleaning roller 3 via this inlet opening 21.
  • the cleaning roller 3 is provided on its outer circumference with impact pins 23, via which the supplied fiber material in cooperation with arranged above the cleaning roller 3 baffles 27 is helically transferred in the direction of the longitudinal axis 12 to an outlet 26 of the cleaner. Subsequently, the cleaned fiber material is transferred to further process stages. In this helical transport within the cleaner 1 the fiber material is passed several times at a mounted below the cleaning roller 3 grate 24, while impurities are separated from the fiber material.
  • FIG. 2 Shown schematically is an embodiment of the device according to the invention, wherein like reference numerals are used for the parts corresponding to the parts of the known embodiment FIG. 1 correspond.
  • a cleaner 1 with a about a longitudinal axis 12 in a cleaner housing 22 rotatably mounted cleaning roller 3 and a condenser 4 with a sieve drum 5 and a feed roller 6 is provided.
  • the screen drum 5 is rotatably mounted in a screen drum housing 14 about a longitudinal axis 7.
  • the feed roller 6 is rotatably mounted in a feed roller housing 18 about a longitudinal axis 8.
  • the condenser 4 and the screen drum 5 is fed via a channel 17 with fiber material 2 by means of transport air 9.
  • the screen drum 5 is connected to its interior 25 with a vacuum source 29.
  • the supplied fiber material 2 is sucked onto the surface 10 of the screen drum 5 and separated by the air-permeable surface 10 of the screen drum 5 of the transport air 9, which passes through the openings of the screen drum 5 and is discharged via the vacuum source 29.
  • a fibrous nonwoven forms on the circumference 10 of the screen drum 5, which is transferred by the, indicated by an arrow direction of rotation of the screen drum 5 to a passage opening 28 in the screen drum housing 14.
  • the formed on the periphery 10 of the screen drum 5 Fasergutvlies is stripped in the region of the passage opening 28 of the arranged below the sieve drum 5 feed roller 6 and conveyed to the inlet opening 21 of the cleaner 1.
  • the ends 15 of the attached to the feed roller 6 on the circumference ribs 11 form an enveloping circle 13 of the feed roller.
  • the feed roller 6 is arranged to the screen drum so that a distance a between the enveloping circle 13 of the feed roller and the surface 10 of the screen drum 5 is made.
  • the distance a is less than 1 mm and in the best case zero, whereby the ends 15 of the ribs 11 during stripping come directly into contact with the surface 10 of the screen drum 5.
  • the ribs 11 additionally form during the stripping process a blocking element for the passage of transport air still in this area 9th
  • the distance b between the outer ends 15 of the ribs 11 of the feed roller 6 and the surface 16 of the cleaning roller 3 is selected from 30 mm to 250 mm. This ensures a continuous transport of fiber material.
  • the fiber material is fed tangentially to the cleaning roller 3 via the inlet opening 21.
  • the cleaning roller 3 is provided on its outer circumference with impact pins 23, via which the supplied fiber material in cooperation with arranged above the cleaning roller 3 baffles 27 is helically transferred in the direction of the longitudinal axis 12 to an outlet 26. Subsequently, the cleaned fiber material is transferred to further process stages. In this helical transport within the cleaner 1, the fiber material is passed several times at a mounted below the cleaning roller 3 grate 24, while impurities are separated from the fiber.
  • FIG. 3 shows in an enlarged schematic representation of a side view X according to the FIG. 2
  • the condenser 4 has a sieve drum 5 with a sieve drum housing 14 and a feed roller 6 with a feed roller housing 18.
  • the screen drum housing 14 is connected to the feed roller housing 18 in the region of a passage opening 28.
  • the longitudinal axis 7 of the screening drum 5, and the longitudinal axis 8 of the feed roller 6 are arranged parallel to the longitudinal axis 12 of the cleaning roller 3.
  • the fiber material is conveyed helically in the direction of the longitudinal axis 12 of the cleaning roller 3 to an outlet 26. This promotion is also supported by above the cleaning roller 3 attached guide elements 27.
  • the deposition of impurities from the fiber material via a mounted below the cleaning roller 3 grate 24, which is repeatedly traversed by the fiber material during transport of the fiber material to the outlet 26.
  • the fiber material discharged downwardly from the feed roller 6 is directly and immediately supplied to an inlet opening 21 of the cleaner 1, whereby it is discharged directly onto the circumference of the cleaning roller 3 provided with impact pins 23.
  • the feed roller housing 18 is connected to the cleaner housing 22 in the region of an inlet opening 21 of the cleaner 1.
  • the condenser 4 is thus placed directly on the cleaner housing 22.
  • the screen drum 5 has a length d and the feed roller 6 a length c, which are equal in size and approximately equal to the width of the inlet opening 21 of the cleaner. Thus, it is not necessary to merge the discharged from the screen drum 5 fiber material. That the fiber material discharged from the screen drum 5 can be fed directly to the inlet opening 21 via the feed roller 6.
  • the outer diameter e of the screening drum 5 can be between 400 and 700 mm, while the diameter f of the enveloping circle 13 of the feed roller 6 can be between 100 and 250 mm.
