Definitions

  • the invention relates to a cleaning machine for textile fibers transported in a conveying air stream, with a horizontal roller with impact elements, under the underside of which bar grids are arranged and over the top of which an inlet for the conveying air stream is arranged at one end of the roller and an outlet at the other end is.
  • At least one such cleaning machine serves to dissolve the fiber flakes supplied in the conveying air flow and to remove impurities from them.
  • the fiber material is dragged over the bar gratings and also tapped to a certain extent by the impact on the walls delimiting the transfer chambers, as a result of which contaminants are detached from the material.
  • Coarse contaminants e.g. Shell parts, pass through the bar grids and are then suctioned off. Fine, dust-like contaminants, however, remain in the known machines at least partially in the conveying air flow and then leave the machine together with the fiber material transported by the conveying air flow.
  • the object of the invention is to design the cleaning machine specified at the outset in such a way that it can largely separate even fine, dust-like impurities from the fiber material.
  • the object has been achieved according to the invention in that after the bar grate arrangement, seen in the conveying direction of the textile fibers, an essentially vertical air and dust-permeable wall is provided, which is part of a vacuum chamber to which a suction line is connected.
  • Air can be drawn off through the air and dust permeable wall, with which the very light, dust-like dirt particles can be separated from the conveying air flow transporting the fiber material.
  • the air- and dust-permeable wall is, for example, a sieve or a perforated plate with holes of approximately 1.5 mm in diameter.
  • Means are preferably provided for setting the negative pressure in the negative pressure chamber.
  • the coarse cleaning machine shown in FIGS. 1 to 3 has an opening roller 1 which is rotatably mounted in a housing 2 about a horizontal axis and the circumference of which is occupied in the usual way with striking pins 3.
  • the roller 1 is rotated in operation by a drive motor, not shown, in the direction of the arrow in FIG. 1.
  • Two bar grids 4 and 5, which are only shown in FIG. 1, are arranged under the underside of the roller 1.
  • the top of the roller 1 is covered at a distance from the circumference of the roller with a wall, of which a horizontal, central section 6 and two laterally adjoining, approximately 45 ° inclined side sections 7 and 8 are provided the wall 7 adjacent, substantially vertical wall 30 is provided, which is permeable to air and dust.
  • the three wall sections 6, 7 and 8 are arranged like a terrace roof, that is to say in cross section approximately like three sides of an isosceles trapezoid, and two of the wall sections each form an angle ⁇ of approximately 135 ° with one another.
  • the wall 30 is formed, for example, by a perforated plate with holes of approximately 1.5 mm in diameter or by a sieve.
  • An inlet line 9 opens into the wall section 7 at one end of the roller 1
  • an outlet line 10 opens into the wall section 8 at the other end of the roller 1.
  • the coarse cleaning machine is supplied with textile fibers to be cleaned and dissolved in flake form in a conveying air flow through the inlet line 9.
  • the conveying air with the fiber flakes essentially flows first around the underside of the rotating roller 1, then through the transfer chamber between the guide plates 11 and 12, which moves the air in the direction of the axis of the roller 1, then again around the underside of the roller, then through the transfer chamber between the guide plates 12 and 13 and again around the underside of the roller 1 to finally leave the machine through the outlet line 10.
  • the flakes of fiber are processed and increasingly dissolved by the striking pins 3, and impurities are separated from the fibers.
  • the coarser impurities such as shell parts, are separated through the bar grids 4 and 5 and out of the space under the bar grids by a suction device, not shown. Then the fiber flakes fly upwards into the next transfer chamber, where they are further loosened and turned by hitting the wall sections 6, 7, 8. Fine, dust-like impurities which have been separated from the fibers can at most be partially sucked off through the bar grids 4 and 5, while a large part of the dust remains in the conveying air flow.
  • the air- and dust-permeable wall 30, the vacuum chamber 20 and the suction line 15 serve to separate these fine impurities from the conveying air flow, so that they cannot ultimately exit through the outlet line 10 together with the fibers.
  • the suction line 15 is connected to a vacuum source or suction device, not shown, which sucks dust-laden air through the wall 30.
  • the size of the vacuum generated in the vacuum chamber 20 or of the air flow sucked through the wall 30 is adjustable, for example by the vacuum source or suction device being adjustable, or by the fact that an adjustable throttle element, for example as shown, is set in the suction line 15 adjustable throttle valve 16 is arranged.
  • the air flow is adjusted so that it is sufficient to suction the dust through the line 15, so that the dust is not deposited on the underside of the vacuum chamber.
  • viewing windows 17 are provided on an outer wall 21, for example as shown in the figures.
  • the purge air inlet 18 also contains an adjustable throttle element, for example a throttle valve 19 (FIG. 4).
  • the inside of the air and dust-permeable wall 30 is always kept clean by the conveying air flow or by the fiber flakes transported by it. If the wall 30 is perforated, then the holes on the inside of the wall should not have any sharp edges so that fibers or contaminants cannot get caught on these edges.
  • the wall 30 can expediently be formed by a perforated plate which has a galvanic coating on the inside. The coating then extends - with a rounded surface - somewhat into the holes.
  • the vacuum chamber 20 it is possible to subdivide the vacuum chamber 20 into a plurality, for example 3, of vacuum chambers 20.1, 20.1, 20.3 and to assign a suction pipe with a throttle valve to each vacuum chamber.
  • the throttle valves are marked 16.1, 16.2 and 16.3.
  • the vacuum chambers 20.1, 20.2, and 20.3 can, as shown in FIG. 4, have assigned the fresh air inlet opening or purge air inlet opening 18 with the throttle valve 19 as a common purge air opening, so that purge air can be accessed to all three chambers.
  • the throttle valve 19 assigns each chamber its own purge air line with a corresponding throttle valve.
  • the subdivision has the advantage that the air flow per section can be made more uniform than with a cross extractor originally shown.
