Definitions

  • the present invention relates to the manufacture of cylinders, and more particularly those used in sugar cane mills for the extraction of juice.
  • the longitudinal channels allow an easy evacuation of the juice extracted from the sugar cane by crushing it between two cooperating cylinders, especially when said channels are arranged in the body of the upper cylinder. The juice is then removed from the ends of the cylinder.
  • the main purpose of the invention is to avoid the difficulties encountered so far, and to propose a particularly simple and economical manufacturing process.
  • a process for manufacturing a cylinder, in particular for a sugar cane mill, for the extraction of juice of the type in which the outer surface comprises circular grooves of cross section in the shape of a triangle.
  • the bottom of each groove communicating with longitudinal channels formed in the cylinder, process according to which one pierces, in a plurality of cross sections of the cylinder, radial channels opening into each longitudinal channel, characterized in that one engages in each radial channel a plug having a blind hole at its inner end, the grooves of triangular cross section which cut the plugs are executed at the periphery of the cylinder, the top of each triangle being located in one of said transverse sections of the cylinder, and l '' is practiced in each throat bottom a circular groove of a depth at least sufficient to communicate the bottom of throat with the e corresponding blind hole.
  • the longitudinal channels are formed by practicing longitudinal grooves at the periphery of the body of the cylinder, and by lining said cylinder body with a ferrule of sufficient thickness to make the radial channels and the circular grooves therein.
  • the longitudinal channels and the cooperating radial channels are executed at constant angular spacing.
  • the plug fitted into said radial channel is glued inside each radial channel.
  • the circular grooves and the longitudinal grooves are advantageously profiled in the shape of a rectangle.
  • the invention also relates to a cylinder, in particular for a sugar cane mill, obtained by implementing the method defined above, characterized in that there is provided, at each of its ends, a passage for flow of the juice defined by a cheek and a deflector disc mounted in a sealed manner around the body of the cylinder and integral with said cheek.
  • the reference numeral 1 generally designates the cylinder constituted by a body 2 jacketed by a ferrule 3, said cylinder body being integral with a shaft 4 by means of which it is driven in rotation.
  • the body 2 has on its periphery longitudinal grooves such as 5, twelve in number in the example shown, whose angular spacing is constant. These grooves define with the internal wall of the ferrule 3 opposite the longitudinal channels 6 of advantageously rectangular section.
  • Channels are made radially in the shell 3, each channel 7 opening into a longitudinal channel 6 whose width is greater than the diameter of the channels 7.
  • the latter are of course, in the example shown, twelve in number for the same section cross section of cylinder 1.
  • Other sets of channels 7 are similarly arranged in other cross sections of cylinder 1.
  • each radial channel 7 Inside each radial channel 7 is housed an insert 8 in the form of a plug, which has at its inner end a blind hole 9.
  • the part 8 is advantageously fitted, then glued inside a radial channel 7. Its inner end is blocked by a shoulder 10 of the bore of the channel 7.
  • Circular grooves 11 are formed on the periphery of the cylinder 1. These grooves have a triangular cross section, the apex of each triangle coinciding with a transverse plane of the cylinder 1 defined by the concurrent axes of the channels 7. The grooves 11 notch simultaneously the ferrule 3 and the added parts 8.
  • a circular groove 12 is formed at the bottom of each groove 11 to communicate the bottom of the groove with the corresponding blind hole 9.
  • each groove 12 is advantageously rectangular.
  • the ferrule 3 has, of course, a thickness sufficient to make the channels 7 and the grooves 11 therein.
  • each cheek 13 is made integral, by means of dishes 14, with a deflector disc 15 mounted around the body 2 of the cylinder 1.
  • An O-ring 16 provides sealing between the body 2 and the disc 15.
  • the dishes 14 for example six in number, are arranged radially at constant angular spacing.
  • Each disc 15 defines with the cheek 13 facing a passage for the evacuation of the juice arriving at the curved end of each longitudinal groove 5.
  • Each disc 15 constitutes a deflector.
  • the longitudinal grooves 5 are machined on the periphery of the body 2, the ferrule 3 is shrunk onto the body, then the radial channels 7 are drilled in the ferrule 3 and the parts 8 are housed in the channels 7.
  • the length of these parts is chosen so that their outer end comes flush with the surface of the ferrule 3 when their inner end abuts against the shoulder 10 of the bore of the canat 7.
  • These parts are fixed, for example by bonding, inside the channels 7.
  • the circular grooves 11 are then machined on the periphery of the shell 3, then the circular grooves 12 which cut the pieces 8 and the depth of which must be sufficient to make the bottom of the grooves communicate with the blind holes 9.
  • the cheeks 13 and the discs 15 are then fixed on the cylinder.
