Definitions

  • This invention relates to a continuous press for solid materials containing liquids toextract the greatest amount thereof to obtain materials" as dry as possible.
  • Fig; 1 shows. a curve of the compression exerted in'a solid material placed in a cylinder permeahle to the liquid-contained in the said'mm:
  • Fig. 2 showsdiagrammatically two compression cylinders.
  • Fig. 3 shows the resultant forces on a point in Fig.1 acted on by;compression.
  • Fig. 5 is an elevation partly in section of the press.
  • Fig. 6 is a plan of the same partly in horizontal section.
  • the present invention is based on the putting 9 into practice of the following considerations.
  • therollersw v C being the thrust of compression. Owing to the rotation of the rollers these latter exert at the surface of the material "tobe come 5 pressed :1 drawing force p R, being the coefficient of frictlonof the metal of the roller on the material being treated.
  • the machine the object of the present invention, is designed to fulfill the above conditions, being formed of two essential and distinct parts consisting respectively in two pressure rollers a and a stationary supporting shafts o, 0 and in a special press formed in three distinct parts as follows: a
  • the body of the press I) is formed in its rear end with a feed hopper c and at'its forward end with a tapered delivery d, e, d e which projects up to the nip of the pressure rollers and has the shape of this latter; Lastly, the continuity of the press allows the arresting disc hereafter described to prevent rotation of themat erial with 5 the screw f hereinafter described and thereby insure longitudinal advancing of the material.
  • the screw 1 which is an 'Archimedean screw, is arranged having in section the form shown in Fig. 5 that is to say spirals of g circular section forwards and spirals of rectangular section rearwards.
  • spirals of the front end of the'screw serve to house the sectors of the disc and those of the rear portion are arranged directly below the jection is engaged between the" forward spirals of the screw 1 thus forming a barrier.
  • the machine comprises two side members i and i suitably held together which carry at their forward end, two fixed shafts ;i i on which rotate v A It may be're'marked that owing to the prethe frame of the press b and the several-driving terial in which the liquid can collect to be reabsorbed by the solid material after pressing.
  • the drive is received by" a pulley It mounted on a shaft l. which is provided with a toothed wheel m.
  • This latter gears with a toothed wheel n mounted on a shaftsq'and through it a wheel n keyed to a shaft -q l v
  • On the two shafts q and q are keyed respectively two pinions r. r 'which gear withtoothed wheels s s mounted on the pressure rollers a a .v
  • the shaft q transmits itsmovement to .bevel wheels t which drive avshaft uwhich operates the pressing elements.
  • the pressure is a 'maximum and may reach 2 to 300'kg per square centimetre.
