Definitions

  • the dosing of the wet mixture is normally carried out by taking from a tank circular the desired quantity by means of buckets most often cylindrical and fitted with shutters. In this tank, the material is introduced already mixed, and a mixer - equipped with blades and scrapers - has for function of preventing material from settling.
  • the measuring cups come to take the material in the tank different distances from the center of rotation; for this reason and the fact by a random factor, even though the cups are completely filled (and therefore that we have volumes even perfectly equal), we are not able to guarantee that the percentages of the different components of the mixture remain equal in each individual well and therefore in all multiple mold compartments or cavities. It may therefore happen that the buckets are filled with different amounts of water and with gaps between the different components of the mixture.
  • the invention therefore relates to a compensation system and in any case for limiting dosing errors in multiple mold cavities of cement briquette presses, in particular of the monolayer type, which have a pressure plate under which several buffers.
  • an elastomer layer associated with each pad which ensures sufficient pressing of the material in the different cavities, even in the presence of limited differences in dosage and composition of the mixture in the different cavities.
  • each buffer is associated with a structure which comprises two plates between which is interposed said elastomer layer and on which this elastomer layer is vulcanized.
  • the two plates are mechanically connected to the means of screws or the like, in order to maintain the connection even in the case where the vulcanization would give way.
  • the elastomeric thicknesses can be interposed between each buffer and the pressure plate which carries said buffers or between each pad and the pad end plate itself, which comes into contact with the material to be pressed.
  • Each elastomer layer may have a hollow peripherally which compensates for the swelling caused in the elastomeric material during the pressure operation.
  • the drawing shows a possible embodiment of the invention, in a vertical section view, in the raised buffer position.
  • the reference 1 designates the base, that is to say the bottom of the mold, on which the frame 3 rests, to define a plurality of cavities 5 two of which are visible in the drawing.
  • the cavity 5 In the cavity 5 are poured quantities of material required to mold M briquettes, each compression operation. These quantities are not always equal in their dosage and composition, which causes differences in the pressing of briquettes and different structures thereof.
  • Reference 7 designates the pressure plate which is lowered by the press to make penetrate into the cavities 5 the buffers 9 fitted with the end plates 11 corresponding, which form the surfaces which come into contact with the material to be pressed to form the briquettes M.
  • the sandwich assembly 13 is obtained by vulcanizing a layer 13A elastomer between two plates 13B and 13C suitably prepared in surface in order to obtain a solid anchorage between the plates themselves and elastomer 13A.
  • Holes 15 are made on the pressure plate 7 for screw 15A for fixing the plate 13B to the pressure plate 7; we are planning also holes for indexing fingers 17 between the pressure plate 7 and the plates 13B, as well as through holes 19 (which protrude from plates 13C and reach the buffer 9), for the passage of security screws 19A which reach buffer 9 and cross it to connect it mechanically to pressure plate 7, with play with respect to the set 13; this is useful in the event that the 13A elastomer layer detachment from one or both plates 13B and / or 13C. Between plate 13C and the buffer 9 are provided for fixing means with the rods 21 anchored in plate 13C and nuts 21A which react in seats provided in buffer 9. There are also finger holes indexing 23 for plates 13C and buffer 9.
  • the specific molding pressure is approximately 200 kg / cm 2 .
  • the elastomer 13A of the sandwich assembly 13 was designed to undergo a crushing of approximately 1 mm, under the conditions mentioned above. In the case where a six-cavity mold 5 is used and in the case where the dosage of the mixture is perfect, in each cavity 5 the sandwich assembly is compressed by approximately 1 mm.
  • the compensation system described above can also be applied to molding of double layer briquettes or other agglomerated products. In these cases, it will be necessary to adapt the elasticity of the elastomer, taking into account the molding pressures specific to each case.
