Definitions

  • the strainer is subdivided 'in vertical direction, so' that in the direction of pressure a number of small low strainers succeed between which points of interruption are arranged which serve as oil outlets.
  • the height of thesmall individual strainers is very low'and the loss from friction is not considerable.
  • Figure 5' illustrates a form of'construction in which the forms of construction shown by Figures 2 and 4 are combined.
  • the tubular strainer shown by Figu-refll works as follows g
  • the lower piston 4 is first raised to the lower edge of the upper strainer ring 2,
  • the piston 3 is operated manuali any suitable means and presses marough the funnell until the ring 2 1s ly or b terial tii -or abutment to filled.
  • the piston-*3 is raisedgto permit'introduction or fresh ma'terialf'and when a predetermlned pressure is reached the piston is lowered by any suitablemeans'to the lower edge of the'nextstrainer ring'2 which allows the cake formed" in the first strainer ring to'descend into'the'neX-t one.
  • press of this construction can therefore ',ure 2'will be' easily understood iromf the 'beused either as' aut omatic'press orasfil'ling j and emptying press for thefbatteries, pro- "vided that the strainer bemovabled;
  • Figure 4 shows a form of construction according to which the entire strainer column is composed of individual strainers with interposed distance pieces, auxiliary devices forcompleting the pressing action of the pistons 3 and '4 being provided.
  • the strainer is composed of the individual strainers and of the distance pieces 6 which form enlargements.
  • a vertical rod 10 traversing the strainer column has small pistons 7, one for each individual strainer, which fit into said strainers.
  • Conical strip- ,pers 8 are arranged above said pistons 7.
  • the rod 10 is adapted to execute a reciprocating movement, a separate drive, e. g., a piston 11, being provided for this purpose.
  • the rod 10 could also be connected with the main pressure piston 8.
  • the rod 10, is perforated'so that the outflow of the oil is facilitated.
  • the material to be pressed drops from the funnel'l into the strainer being pushed inby the .piston 3.
  • the pistons 7 aresituated in the enlarged distance pieces 6 ig. 4) so that the material can get around the pistons 7 and around the strippers 8.
  • the material to be pressed consistsof oil containing substances it does not fill the strainer automatically but has to be pushed down bythe reciprocating motion of the rod 10 withthe pistons 7 and strippers 8, the material being thus preliminarily pressed.
  • the pressing proper begins as the pistons 7 are moved by the rod 10 from the enlarged distance pieces 6 into the corresponding strainers 2.
  • the pistons findan increased resistance, which results on the one hand from the filling of the strainers and on the other hand from the pressure exerted'by thepistons 3 and 4, the pressure a'ctmg much stronger in the narrow strainers than in the enlarged distance piepe's 6.
  • the piston 4 is lowered manually or by any suitable means known the art and part of the lowest cake will be expelled as the lowest small piston/7 descends down to half the height of the lowest strainer 2. Some space will Y thus get free in the lowest enlarged distance pistons is thereby drawn along by piston 3 so that these pistons are situated again in ance so that the material which has just been fed into the strainers is compressed.
  • the strokes of the rod 10 and of the piejtons 7 are short. They are determined first by the position of the pistons 7 in the enlarged distance pieces 6 during the charging operation, secondly by the position ofthe pistons at each pressing, thirdly by the position of the pistons at the idlestrokeas'in this case the pistons. go down "to the lower edge of the narrow strainers 2 to expel the whole cake. 1 a
  • a ringfstrainer with annular pistons 3 and 4 is arranged below tubular strainers constructed as. described with reference to Fig. 4 .
  • the tubular strainers have pressing pistons 30 and 40'
  • the upper annular piston 3 for the ring strainers surrounds the tubular strainers.
  • the ring strainer has distance pieces 6, the tubular strainers have enlargements 60 between the narrow strainers 2.
  • Conduits 9 serve for connecting the outlets of the tubular strainers with the funnels 1 of the ring strainer.
  • I claim v v An improved strainer for oilpresses comprising a number of superposed indi- Vidual strainers of low height offering little resistance from friction and distance pieces separating the superposed strainers.
  • An improved strainer for oilpresses comprising a'number of superposed individual strainers of low height offering little resistance: from friction, distance pieces separating'the superposed strainers, a reciprocating rod axially arranged in said strainer and pistons upon said red 'one for each individual strainer.
  • An improved strainer for oilp'res'ses comprising a number of superposed individual strainers of low heightofi'ering little resistance from friction, distance pieces separating the superposed strainers, a reciprocating rod axially arranged in said strainer, pistons upon said rod one for each individual strainer and a stripper over each of said pistons on the rod.
  • An improved strainer for oilpresses comprising in combination anumber of superposed ring-shaped strainers, distance pieces between said individual ring shaped strainers, a pressure piston at the upper end of the column of ring-shaped strainers and a counter pressure piston at the lower end of for alternately loosening and compressing the material to be compressed, said tubular columns being arranged above said ring shaped strainer column and conduits, con necting the outlets of said tubular" strainer column with the inlets of said ring-shaped strainer column, substantially as described and shown and for the purpose set forth.
