Definitions

  • the invention relates to an assembly for carrying out the steps of pressing and suction of water in the processes of production of tiles, in particular of single-layer tiles.
  • FR 2 945 234 A discloses an apparatus for presses for the production of single-layer tiles starting from a water-based compound, comprising:
  • An aspect that can be improved of the known systems is linked to the relative difficulty in keeping the filtering and suction system clean, and to the relative frequency of replacement of the filters used in removing the liquid phase in excess from the mix.
  • the purpose of the present invention is to overcome the drawbacks of the solutions already known and propose equipment that is simple to produce, convenient to use, and that will, at the same time, enable a high efficiency during operation and ease of cleaning between one working cycle and the next.
  • a first advantage of the invention consists in the capacity of the assembly to guarantee a uniform distribution of the action of suction, and hence effective removal of the water in the entire mass of the mix.
  • a second advantage consists in the ease of disassembly and cleaning of the assembly and in the elimination of the need to provide a subfilter to be replaced continuously together with the filter.
  • a third advantage consists in the reduction of the frequency of .replacement of the filters as compared to known systems.
  • a suction and pressing assembly 2 for presses 1 for the production of single-layer tiles starting from a water-based compound 3 contained in a bottom tank 4, of a type in itself known.
  • the assembly 2, illustrated in Figure 1 comprises in particular a top lid 5 provided with openings 28 with perimetral seals 29, in communication with a system for suction from above, which is provided with holes 16 and forms part of a buffer suction assembly 9 to which the lid 5, made of ferromagnetic material, is fixed via magnetic actuators 23 and centring pins 24, and screws envisaged in the case of malfunctioning of the actuators 23.
  • the suction system comprises at least four holes 16 arranged on the diagonals of the buffer 9 for transferring suction to the holes 28, 28A, 28B of the lid 5.
  • the lid 5 can be preferably divided into four suction areas each supplied by a hole 16.
  • a top collector 6 and a perforated plate 7, Arranged in succession underneath the lid 5 are a top collector 6 and a perforated plate 7, which are removably applied to the bottom face of the lid 5, preferably via pins 13 passing through corresponding reference holes 14 for centring with respect to a common orthogonal axis 15 and via fixing screws 13a that render the elements 5, 6, 7 just described fixed with respect to one another.
  • the plate 7 is comprised between the top collector 6 and a bottom collector 8, positioned underneath which is a filter 11 connected by means of a system of removable peripheral frames 12, which are sealingly inserted in a corresponding seat 26 of the plate 7.
  • the plate 7 has a substantially plane top surface 17 and a substantially plane bottom surface 18 traversed by a uniform distribution of holes 21 in communication with said top collector 6 and bottom collector 8.
  • the top collector 6 has in its thickness a distribution of openings 29A, which are connected to the openings 28 of the lid 5 and from which there branch off branched channels 30 to which there correspond the holes 21 of the underlying plate 7 (more, clearly visible in Figure 8 )
  • the plate 7 has a distribution of inclined holes 27 that communicate with separate channels 30A of the top collector 6 and with the sides 22 of the plate 7 in the proximity of the corners 39 (more clearly visible in Figure 5 ).
  • the plate 7 rests on the bottom collector 8 as may be seen more clearly in the detail of Figure 5 , which is preferably formed by a metal-mesh structure with superposition of criss-crossed wires 19, 20.
  • the metal-meshlike conformation of the collector 8 renders the task of cleaning thereof between successive working cycles convenient and in any case not overly frequent with respect to the replacement of the filter 11.
  • the collector 8 is preferably fixed to the plate 7 by means of screws 90 so as to simplify the operations of replacement of the filter 11.
  • top collector 6 is fixed to the plate 7 by means of screws 91.
  • Disassembly is carried out only when it is intended to perform a more accurate cleaning of the channels 29A and 30A.
  • the assembly 2 is fixed to the machine 10 as represented schematically in Figure 2 and is in contact with the mix 3 following upon the descending stroke of the buffer 9, which brings the filter 11 into contact with the liquid phase emerging from the mix 3.
  • the machine 10 executes one or more suction steps in order to take in the liquid phase in excess through the assembly 2 and remove it through the suction ducts 16.
  • the negative pressure generated in the ducts 16 is transmitted in succession through the openings 28 and 29A of the lid 5, the collector 6, the holes 21 and 27 of the plate (the holes 27 collect the water not filtered laterally by the frames 12), and the collector 8 and reaches the filter 11 in contact with the mix.
  • the meshlike conformation of the bottom collector 8 enables the liquid phase sucked in (generically designated by H 2 0 in Figure 5 ) to migrate easily and uniformly through the gaps formed by the superposition of the crossed metal wires 19, 20 of the collector, and be effectively removed through the holes 21 of the plate 7, and then traverse the top collector 6 and be removed through the ducts 16.
  • the assembly 2 is simple to assemble, and the various components can be easily cleaned thanks in particular to the plane geometry of the plate and the meshlike conformation of the bottom collector 8.
  • the meshlike conformation of the collector 8 facilitates vertical passage of the aqueous phase taken in and at the same time facilitates horizontal migration given that it enables an even very dense distribution of holes 21 of the plate, and hence enables a uniform negative pressure on the entire surface of the area of pressing to be obtained.
  • the density of holes 21 is greater in the proximity of the diagonals of the plate and of the corners, which are frequently the areas that involve a greater removal of liquid in excess.
  • a plate 7 according to the invention assembled with the top collector 6 and bottom collector 8 of the type already described, a filter 11, and the frames 12.
  • the plate 7, together with the frames 12 and the filter 11, defines a plate assembly 70 delimited at the bottom by a pressing surface made up of a perimetral surface 32 of the plate, a surface 33 defined by the frames 12, and a surface 34 defined by the filter 11, where the surfaces 32, 33, 34 are all at the same level thanks to the creation in the plate 7 of a seat 35 that houses precisely the collector 8 on which the filter 11 is set, at the same time obtaining a proper centring of the collector 8 with minimum perimetral play.
  • the plate 7 and the frames 12 have respective inclined surfaces 36, 37 substantially parallel and set apart by an amount equal to the thickness of the filter 11 as equal to the same thickness is also the distance between the plane defined by the surface 33 of the frames 12 and the plane defined by the bottom surface 38 of the plate 7 in the internal perimetral area in which the filter 11 is applied and which encloses the seat 35 of the collector 8.
  • the filter 11 does not have the possibility of bending or deforming, except for the minimal perimetral play existing between the collector 8 and the seat 35, thus obtaining a top face 43 of the tile that is perfectly plane.
  • top collector 6 and the plate 7 are combined in just one plate made of a single piece 67, maintaining the same functionalities already described above and the corresponding technical advantages.
  • this embodiment which is adopted when certain dimensions are exceeded or for particular embodiments of the product being manufactured, achieves an even better draining effect and enables reduction of the production costs.
