Definitions

  • the present invention refers to a system for compacting ceramic powders for forming slabs using a belt.
  • the dry forming process of ceramic powders on a belt foresees the use of compacting belts, bottom and top respectively, cooperating to dry compact a strip of ceramic powders that is made to advance, through a conveyor belt arranged between them, in an advancing direction parallel to the bottom belt.
  • the compacting is assisted by two compacting rollers kept pressed against the strip of ceramic powders.
  • the top belt has a first receiving portion inclined with respect to the advancing direction of the powders and a second expansion portion respectively upstream and downstream of the compacting rollers present in the compacting area.
  • the inclination of the first portion of the top belt, with respect to the advancing direction of the strip of powders, ensures a progressive squashing of the powders and allows the air present inside them to be expelled.
  • EP 1226927-A2 discloses a system for compacting ceramic powders according to the preamble of claim 1.
  • the phenomenon is more noticeable when strips of ceramic powders of a thickness greater than 30 mm are processed.
  • a further drawback of known systems derives from the fact that the receiving portion of the top belt, due to the rather small inclination, less than 2°, implies an elongation of the receiving portion of the powder that is increasingly great the greater the thickness of the powder.
  • the continuous compacting has a use limited to small thicknesses of powder with low degrees of compacting (reduction in thickness no greater than 30%).
  • the purpose of the present invention is that of providing a system for compacting ceramic powders for forming slabs using a belt that ensures the complete expulsion of air, during compacting, also for high thicknesses of powders and degrees of compacting.
  • a further purpose is that of providing a system that has a limited size, bulk and costs compared to those of the
  • Such purposes are accomplished through a system for compacting ceramic powders for forming slabs using a belt in accordance with claim 1.
  • a system for compacting ceramic powders for forming slabs using a belt in accordance with the present invention is globally indicated with 1.
  • the system 1 comprising a conveyor belt 40 on which a continuous strip "S" of powdered ceramic material is created, a first bottom compacting belt 20 arranged in contact with the conveyor belt 40 and a second top compacting belt 30 cooperating with the first belt 20 to dry compact the strip S of powders and obtain a coherent article of compacted powders.
  • the top belt 30 has a first housing portion 30a, arranged on the left in the figure, and a second expansion portion 30b, arranged on the right in the figure.
  • the lateral containment of the powders is, as usual, carried out by two deformable side walls provided by the belts 60.
  • the receiving portion 30a of the top belt 30 has an inclination " ⁇ " with respect to the direction in which the powders advance of between 2° and 14°, preferably between 3° and 10°.
  • each belt 20, 30 is wound on a pair of rollers, one of which is a drive roller, respectively indicated with 32 for the top belt 30 and with 22 for the bottom belt 20, and the other is an idler roller, respectively indicated with 31 for the top belt 30 and with 21 for the bottom belt 20.
  • rollers 31, 32 and 21, 22 of each pair are arranged a distance apart such as to keep the respective wound belts 30, 20 taut.
  • the bottom belt 20 and the top belt 30 are equipped with a compacting roller, indicated with 33 for the top belt 30 and with 23 for the bottom belt 20.
  • the two compacting rollers 33 and 23 act directly on the belts 30, 20 at the tangency points, indicated with 34 and 24 respectively for the top belt 30 and for the bottom belt 20.
  • the distance between the two tangency points 34 and 24 is equal, apart from the thicknesses of the belts, to the minimum gap through which the strip S of powders is forced to pass.
  • two rollers 36, 26 are arranged, formed from a plurality of idler rollers, which act on the respective belts 30, 20 upstream of the two compacting rollers 33, 23 and that have the function of keeping the belts 30 and 20 pressed to press the strip of powders S.
  • the respective axes of the compacting rollers 33, 23 lie on a common plane perpendicular to the direction in which the strip S of powders advances.
  • the minimum distance between the two belts 30, 20 and therefore the distance between the two compacting rollers 33 and 23 must be varied, i.e. the mutual position between the tangency points 34 and 24.
  • top belt 30 is distanced from the bottom belt 20 through the displacement of the rollers 31, 32 on which it is wound.
  • the inclination " ⁇ " of the first receiving portion 30a can also be varied, as desired between 2° and 14°, preferably between 3° and 10° with respect to the direction in which the strip S of powders advances.
  • the point of first contact, indicated with 50, between the strip S of powders and the receiving portion 30a itself of the top belt 30 gets closer to the compacting rollers 33, 23, whereas they move away as the thickness of the strip S increases.
  • the choice of the most suitable inclination P to be assigned to the receiving portion 30a to effectively remove the air incorporated in the powders to be compacted is carried out taking into account the specific properties of the powders to be treated.
  • the length A of the portion of strip S of powders involved at the instant of compacting must be between 2 and 28 times the thickness of the strip S.
  • the length A is equal to that of the projection, on the conveyor belt 40, of the distance between the point of first contact 50 of the top belt 30 by the strip S of powders and the tangency point 34 of the compacting roller 33 with the top belt 30.
  • the system for compacting ceramic powders for forming slabs using a belt according to the present invention allows the requirements to be satisfied and allows the drawbacks mentioned in the introductory part of the present description with reference to the prior art to be overcome.
