Definitions

  • the invention relates to a cleaning machine for textile fibers transported in a conveying air stream, with a horizontal roller, equipped with impact elements, under the underside of which bar grids are arranged and over the top of which an inlet and the other end an outlet for the conveying air stream and at the other end of the roller delimited transfer chambers for the air flow rotating about the roller axis are arranged between the inlet and the outlet of guide plates inclined to the roller axis.
  • At least one such cleaning machine is known and available on the market. It 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 grates and also tapped to a certain extent by the impact on the walls delimiting the transfer chambers, as a result of which contaminants are released 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 the transfer chambers are at least partially covered with an air- and dust-permeable wall over which at least one vacuum chamber connected to a suction line is formed by a hood is.
  • Air can be sucked out of the transfer chambers through the air- and dust-permeable wall of the transfer chambers, with which air the very light, dust-like dirt particles can be separated from the conveying air stream transporting the fiber material.
  • the air- and dust-permeable wall of the transfer chambers is, for example, a sieve or a perforated plate with holes of approximately 1.5 mm in diameter.
  • each transfer chamber - or possibly in one or some of the transfer chambers - it can form at least part of the cover.
  • the vacuum chamber can be assigned to all transfer chambers together; however, it is also possible to arrange separate vacuum chambers for each of the transfer chambers or for each of some of the transfer chambers.
  • Means are preferably provided for adjusting the negative pressure in the negative pressure chamber or the negative pressure chambers or the amount of air drawn off by them, e.g. an adjustable throttle valve in the suction line or between it and the vacuum chamber. If there are several separate vacuum chambers, each of them can also be assigned its own throttle element (flap, slide or the like).
  • 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 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 °.
  • the wall sections 6, 7 and 8 are 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.
  • a hood formed by an upper part 2a of the housing 2 delimits a vacuum chamber 14 above the wall with the wall sections 6, 7, 8, to which a suction line 15 is connected.
  • the coarse cleaning machine has flake-like textile fibers to be cleaned and dissolved supplied 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 rod grids 4 and 5 and sucked out of the space under the rod grids by a suction device, not shown. Thereafter, the fiber flakes fly upward into the next transfer chamber, where they are further loosened 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 sections 6, 7, 8, the vacuum chamber 14 and the suction line 15 serve to separate these fine impurities from the conveying air flow, so that they cannot end up with this and the fibers through the outlet line 10.
  • the suction line 15 is connected to a vacuum source or suction device, not shown, which sucks air laden with dust through the wall sections 6, 7, 8.
  • the size of the negative pressure generated in the negative pressure chamber 14 or of the air flow sucked through the wall sections 6, 7, 8 is adjustable, at for example in that the vacuum source or suction device is adjustable, or in that an adjustable throttle element, for example an adjustable throttle valve 16, is arranged in the suction line 15.
  • 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 top of the wall sections 6, 7, 8.
  • viewing windows 17 are provided in the upper housing part 2a, for example as indicated in FIG. 1 on the upper side thereof. It may also be expedient to arrange at least one purge air inlet 18 in the upper housing part 2a, through which purge air can be sucked into the vacuum chamber 14 from the surroundings.
  • the purge air inlets 18 also contain adjustable throttle elements, for example throttle valves 19 (FIG. 2).
  • the underside of the air and dust-permeable wall sections 6, 7, 8 is always kept clean by the conveying air flow flowing through the transfer chambers or by the fiber flakes transported by it. If the wall sections 6, 7, 8 are perforated, then the holes on the underside of the wall sections should not have any sharp edges so that no fibers or contaminants can get caught on these edges.
  • the wall sections 6, 7, 8 can expediently be formed by a perforated plate which has a galvanic coating on the underside. The coating then extends - with a rounded surface - somewhat into the holes.
  • the wall sections 6, 7, 8 are essentially permeable to air and dust over their entire surface.
  • FIG. 4 shows again the three guide plates 11, 12 and 13, which delimit two transfer chambers above the top of the roller 1, which are covered with an air and dust-permeable wall. From this wall sections 6 'and 7' are visible. Above the wall, two vacuum chambers 20 and 21 are formed, which are delimited by partitions 22, 23 and 24. The partition walls 22, 23 and 24 are aligned with the guide plates 11, 12 and 13, so that each of the vacuum chambers 20 and 21 is aligned with one of the two transfer chambers.
  • the vacuum chambers 20 and 21 are each connected via an outlet 25 or 26, in each of which an adjustable throttle valve is arranged, with a suction line 15 '.
