Definitions

  • a rotary or drum-type drier for drying textiles is disclosed.
  • the drier has a plurality of inclined drum means, each of which is inclined at a different angle. In one embodiment all the drums are inclined downwardly. In a second embodiment the drums at the charging end are inclined upwardly, while the drums at the discharge end are inclined downwardly. The heated air runs countercurrent to the wash.
  • the present invention relates to a rotary or drum-type drier of the kind as frequently used for drying textiles and, for example, washing.
  • Such rotary driers are charged with the washing from a dewatering or water-separating appliance (such as spin drier, roll press).
  • drums In the case of large drying capacities there actually result drums whose lengths of, e.g., 2 to 3 metres and more, amount to a multiple of the drum diameter.
  • the washing when being charged continuously and at otherwise constant data, forms a layer of predetermined thickness on the inside cylinder surface of the drum, with this layer thickness remaining uniform throughout the entire length of the drum.
  • the thickness of this layer if possible, neither shall fall short of nor exceed a predetermined value, so that the drying airstream which is being supplied in a constant amount and at a constant temperature by a blower, will always achieve the same degree of dryness. Operation becomes uneconomical when this layer is too thin, because too much heat is being afforded. On the other hand, if this layer is too thick, the airstream is prevented from reaching those pieces of washing lying close to the inner circumference of the drum.
  • the layers appear to be too thick in conventional types of machines, for safeguarding an optimum drying.
  • the pieces of Washing also the large ones, such as linen sheets, to be discharged from the drum individually, and not to be partly already positioned on the discharging conveyor belt while other parts are still being retained within the layer and are thus prevented from falling out.
  • dimensioning at the discharge point would have to be made thus, that the layer becomes thinner in order to allow individual pieces to drop out.
  • the object of this invention is to improve these operational conditions with respect to rotary driers employing slopingly arranged drums.
  • the main feature of the invention resides in that the rotary drier consists of several individual drums, each of which having a difiFerent sloping position.
  • the sloping position of each of the individual drums with the exception of that particular part by which the discharge is effected, can be dimensioned so that an optimum drying effect can be obtained, whereas the individual drum from which the discharge is effected, can be adjusted so as to obtain a smaller layer thickness. Accordingly, there is reliably avoided the formation of lumps of washing, and the dried pieces are discharged as individual parts from the last drum.
  • the drum parts are designed as individual drums successively coupled to one another, with the supporting frames thereof being joined among each other with the aid of hinges.
  • these individual drums are pivoted on the supporting frame in the manner known per se, with the aid of supporting and driving rollers, and with these driving rollers being driven by a common shaft comprising joints or hinges at the junction points between each time two supporting frames.
  • the drums may be arranged to have a different sloping position towards the discharging (unloading) point, i.e., to descend from above towards below. According to a further feature of the invention, however, it is particularly advantageous to let the drum or the individual drums respectively, slope upwardly throughout a longer section, for being then designed to slope downwardly within a shorter section and towards the discharging end.
  • the invention also has for its object the circulation of the drying airstream passing through the drums from the discharging end in opposition to the movement of'the washing or goods to be dried.
  • the emptying can be accomplished by employing the used or exhaust air which, at the charging point for the washing, is being passed axially through all of the individual drums.
  • FIGS. 1 and 2 show the invention in a schematic representation
  • FIGS. 3 and 4 show the supporting frames and the drive mechanism
  • FIGS. 5 to 7 show the circulation of air with respect to the individual drums and the housings thereof.
  • FIG. la shows that the partial drums 3, 4 and 5 rotate about the axis 6 and are being traversed or passed through by the washing in the direction as indicated by the arrow.
  • FIG. lb shows an arrangement of the drums in which the individual drums 3 and 4 are upward-sloping from the charging point and with respect to the horizontal line, and in which the individual drum 5 is downward-sloping. In this way it is accomplished that transportation of the washing inside the drums 3 and 4 is determined by the rate at which these drums are being charged. Drum 5, however, discharges the washing in accordance with its respective sloping position.
  • FIGS. 3 and 4 show the technical embodiment of the invention.
  • the supporting frames 9 serving the drums 3 to 5 rest on supporting members 11 and 12 and, by way of joints or hinges 10, are coupled at one end to a fixed point and otherwise among each other.
  • a motor 13 serves to drive, via a belt or chain drive 14, a shaft 15 to which there are mounted the supporting and driving rollers 16 for the drums 3 to 5.
  • the shaft 15 is equipped with joints or hinges 18 which take care of ensuring the driving whenever the drums are brought into the sloping position.
  • the adjustable supporting members 11 and 12 of which, in the case of lighter constructions, the supporting members 12 may be omitted.
  • the supporting frames 9 will be caused to turn about the joints or hinges 10, thus permitting the setting of different sloping positions for each individual drum.
  • the joints or hinges 18 may be designed as flexible couplings, because there are only concerned slight deviations from the horizontal line.
  • one aggregate according to the aforementioned data permits a throughput of 1000 to 1500 kg. of washing per hour.
  • 300 to 400 kg. of Washing can be processed per hour, whereas in cases of complete drying, as is preferred, e.g., with respect to baby washing (napkins), 200 to 300 kg. of washing can be processed per hour.
  • FIGS. 5 to 7 show the housings for the individual drums, as well as the air circulation.
  • FIG. 5 shows a novel view of two housings
  • FIG. 6 shows a vertical sectional elevation
  • FIG. 7 shows a top view.
  • the complete drier may be composed of any arbitrary number, at least however, of two such housings.
  • the fresh air is being sucked at point 21 by the blower 23 and, in doing so, is heated in the heat exchanger 22 which may be heated, e.g., with vapour or electrically.
  • This fresh airstream passes through the drum 24 and into the channel 26 which, with the aid of air deflectors 27 (FIG.
  • each drum has a heat register and a blower of its own, so that one drier may consist of several drum supporting frames. For the sake of simplicity only two such frames are shown in FIGS. 5 to 7 although, as a rule, three to six of such frames are required.
  • FIGS. 5 to 7 For the sake of simplicity only two such frames are shown in FIGS. 5 to 7 although, as a rule, three to six of such frames are required.
  • a special flap 29 positioned in the exhaust airstream of the exhaust blower 30.
  • One such exhaust blower is only required to be arranged at the drum charging (loading) the drier. In the operational condition the flap 29 (FIG.
  • drums of an equal sloping position can be combined to form one single drum, with the sloping position capable of being firmly adjusted in advance.
  • a rotary drier for textiles comprising drum means, means for slopingly supporting said drum means, said drum means comprising a plurality of individual drums of equal diameter, said drums being inclined at different angles from the horizontal; and means for revolving said drums at the same speed and in the same direction.
  • a rotary drier according to claim 1 wherein the sloping position of said individual drums increases downwardly from the charging end of said drum means towards the discharging end.
  • a rotary drier according to claim 1 wherein the individual drums at the charging end of said drum means slope upwardly and the individual drums at the discharge end of said drum means slope downwardly, said upwardly sloping drums comprising a greater portion of said drum means than said downwardly sloping drums.
