Definitions

  • ABSTRACT adjustable pressing means and is arranged above the perforated cylinder and laterally of the latter.
  • the shaft of the pressing cylinder is displacable in slides and subject to an action tending to bring it towards the perforated cylinder.
  • the invention relates to apparatus for drying fibrous materials of the sugar cane bagasse type, especially for the treatment of this bagasse at the outlet of a cane sugar extraction installation.
  • the bagasse at the outlet of the extraction installation, is first distributed by a heavy and cumbrous apparatus, e.g., a rotary scraper, or by a set of equally cumbersome screws. Then this bagasse is led by conveyors on to a first mill with three cylinders, called a repressing mill, which has the task of extracting a portion of the water with which the bagasse is charged.
  • a heavy and cumbrous apparatus e.g., a rotary scraper
  • this bagasse is led by conveyors on to a first mill with three cylinders, called a repressing mill, which has the task of extracting a portion of the water with which the bagasse is charged.
  • An advantageous embodiment consists in having recourse to an apparatus with two substantially horizontal cylinders, one being of smaller diameter and arranged above a perforated extractor cylinder of larger diameter, and laterally thereof, said perforated cylinder comprising means thereinside to collect the liquid and discharge it at least at one of its ends.
  • the invention comprises, apart from these features, certain other features, which are preferably used at the same time and which will be more explicitly considered below.
  • FIG. 1 is a transverse cross-sectional view of one embodiment according to the invention for the treatment of sugar cane bagasse;
  • FIG. 2 is a longitudinal crosssectional view thereof
  • FIG. 3 is a transverse cross-sectional view of another embodiment.
  • the procedure in order to treat, for example, bagasse provided from a sugar cane extraction installation, to extract the juice from it, the procedure is as follows.
  • the bagasse is made pass between at least two cylinders, arranged side by side and leaving a certain space into which the bagasse is forced to pass the two cylinders rotating for this purpose in reverse sensese, at least one of these cylinders being perforated, and being provided with means adapted to receive the liquid and to conduct it towards one of its ends.
  • the distance between the cylinders is adjustable and hence the cross-section for the pase sage of the bagasse can be regulated, this against the action, also possibly adjustable, of elastic or other means, tending to urge the cylinders together and consequently to exert a gripping action on the bagasse.
  • the extractor cylinder 1 is forexample driven by gears 14, 15 from a shaft 16 actuated by a motor 17,
  • the pressing cylinder 2 driven itself by another motor 18, is displacable for example by means of slid ers 19 (FIG. I) movable in slides 20, and its shaft 12 is subject to the action of a force tending to urge it closer to the extractor cylinder.
  • This force is developed for example by a counterweight 21 ssupended on a cable 22 passing over pulleys 23, 24, any other system, of course, being conceivable. Recourse could especially be had to jacks, springs, etc.
  • This assembly is completed by a hopper 9 which brings the bagasse above the cylinders, and by projections or blades 10 provided on the outside of the cylinders for driving said bagasse between the cylinders.
  • Conveyer means for example a belt 11, is in addition provided below the cylindersifor the removal ,of the dried fibers.
  • this can be constituted by men .bers such as gutters .or the like, adapted to channel the said liquid suitably (if necessary, as indicated above, a certain slant of the cylinders could assist this extrac! tion).
  • collector means can be, either fixed to the wall of .the extractor cylinder thereby turning with thelatter, or on the contrary be non-rotary.
  • Said means consists of 25 provided axially between the wall of the cylinder 3 and a central .cone 26 whose apex is directed towards the outlet of the liquid.
  • This outlet is constituted by a spout .8, anyother means being .1usable.
  • FIG. 3 Another arrangement is shown in (FIG. 3) and consists in providinginside the cylinder I, assumed to turn by suitable ,befarings on the shaft 13 assumed non-rotary, an inclined partition 27 (shown diagrammatically at MN in :FIG. .3,
  • This partition 27 collects at its upper part at M the juice extracted from the bagasse and allows it to flow towards the lower part at N. At this spot, the juice is led to traverse the cylinder again, through the perforations 3, and is collected in a suitable gutter.
  • an assembly such that the bagasse is introduced between cylinders whose separation and speed of rotation are selected so as to distribute the product while making it undergo compression at the time of its passage between the cylinders.
  • a large portion of the liquid passes hrough the holes of the perforated cylinder, to be received in the receiver means and to be removed towares the outlet gutter, while the dried fibers are themseleves removed by the conveyor or the like. It is understood that, if necessary, two successive trains of rollers could be provided.
  • Apparatus for drying fibrous material of the sugar cane bagasse type comprising in combination:
  • separare motors for respectively rotating said cylinders in order to cause said fibrous materials to pass between and be pressed in a space between cylinders
  • Apparatus according to claim 1 comprising a mechanical, guide system supporting the pressing cylinder and allowing the latter to be displaced under the action of the pressure force developed between the cylinders upon passage of the fibrous material between said-cylinders.
  • Apparatus according to claim 1 wherein the means for removing liquid includes a liquid collector at least at one end of the perforated cylinder.
