Definitions

  • the present invention relates to a grid plate for an oscillating type conveyor intended in particular for the transport of crushed products and, in particular, of hot divided products such as "clinkers” involved in the manufacture of cements and which must be cooled during their transfer between a baking oven and the next processing station.
  • Such conveyors are formed by a set of juxtaposed grid plates with partial overlap, the plates of a row in two, transverse to the direction of transfer, being mobile and driven in an alternating movement by translation from side to side. other from an average position in said direction of transfer.
  • both the fixed plates and the movable plates are subjected to significant stresses and must, on the one hand, be firmly fixed to their respective supports and, on the other hand, be easily removable from these same supports for their rapid replacement not requiring a prolonged stop of the entire carrier.
  • the present invention aims to meet these requirements, by providing a plate for a conveyor of the type mentioned above and which can be mounted on the fixed supports or the mobile supports of said conveyor.
  • a plate has a flat or dihedral upper face with a rounded edge on the downstream side and, on its lower face, a rib transverse to the direction of transport, provided with a tab pierced with a orifice in the longitudinal direction for fixing bolt, as well as two lateral wings each comprising, at the level of said transverse rib and at their end opposite to said flange, a recess intended to cooperate with a respective transverse support bar of complementary shape, whereby the plate is supported at four points.
  • a conveyor of the type considered is intended for the transport of a material in the divided state in the direction of arrow F1 and comprises, transverse to the direction of this arrow, rows of fixed plates of general reference 1 alternating with rows of mobile plates of general reference 2.
  • the fixed and mobile plates are mounted on substantially identical supports respectively comprising fixed uprights 3, 4 secured to a spar 5, and movable uprights 6, 7 secured of a frame 8 movable in translation on either side of a mean position M, parallel to the plate 2 according to the arrows F2 and F3.
  • a plate according to the invention is of generally rectangular shape and comprises an upper face 9, for example flat, in contact with the material to be transported, a lower face 10 provided with reinforcements and members mounting, a rounded edge 11 being disposed on the transverse edge directed in the downstream direction of transport.
  • the downstream part of the plate, not covered by the adjacent plate comprises orifices 12 for blowing air, the latter being directed along arrow F4 on the lower face. towards the upper face.
  • a plate has two lateral wings 13 parallel to the longitudinal axis AA (FIG. 2) and substantially perpendicular to the plane of the upper face 9, as well as a transverse rib 14 in a substantially median position and connected by its two ends of the respective wings 13.
  • a second rib 15 is also arranged along the axis AA between the downstream flange 11 and the transverse rib 14.
  • Each wing 13 comprises at its end opposite the flange 11 an end recess 16 giving it a length slightly weaker than that of the upper face 9 in the direction of the axis AA.
  • a notch 17 is, moreover, formed between the end part 16 and the lower face 10.
  • the transverse rib 14 has at its central part a tab 18 directed opposite the upper face 9 and provided with an orifice 19 in the longitudinal direction parallel to the axis AA and the edge of which is suitably reinforced by an additional thickness.
  • the recesses 16-17 and the orifice 19 constitute the bulk of the elements for fixing the grid to its support.
  • each support consists of the uprights 3, 4 and 6, 7 disposed respectively at the junction between two juxtaposed plates, in the transverse direction parallel to the axis' BB. Between these amounts is further reported a veil 20 of suitable thickness, also in the transverse direction.
  • An orifice 21 is drilled in each "downstream” sail disposed between the uprights 3 or 6, in the extension of the orifice 19 of the plate, to allow passage to a fixing bolt 22.
  • an attached transverse bar 23 projecting from the side directed towards the downstream upright, the upper face of said bar and the corresponding upright being in the same plane.
  • each wing 13 also comprises a second recess at the level of the central rib 14, formed by a projecting part 24 directed on the side opposite to the upper face 9 and provided with two faces 25, 26 at right angles directed towards the upstream end of the plate.
  • the face 25 is perpendicular to the plane of the upper face, while the face 26 is parallel to said plane.
  • These two faces are of complementary shape with respect to a transverse bar 27 arranged at- above the downstream supports 6, the face 26 having a suitable excess thickness and coming into abutment on said bar 27.
  • the fixed plate bears at four points, namely, the two faces 26 and the two lower face portions 10 associated with the recesses 16 and provided with suitable reinforcements 28.
  • an alternative embodiment of a plate according to the invention has all the characteristics of the embodiment described above with regard to the fixing and support members. It simply differs from it by its dihedral upper face 29, 30 the edge of which is disposed substantially in line with the transverse rib 14.
  • the upstream plane 29 of the dihedral is intended to be substantially perpendicular to the uprights of the support, while the downstream plane 30 of the dihedral is raised towards the downstream direction.
  • the rounded rim 31 forms a weir useful for certain applications, the foot of the downstream edge 32 of the weir being substantially in the same plane as the lower edge of the upstream portion of the wings 13, the lower edge 33 of the downstream portion of the said wings being parallel in the downstream plane 30 of the dihedral.
  • the four-point mounting according to the invention has many advantages, in addition to the ease and speed of installation and dismantling, in particular the fact that the contact surfaces between plate and supports are limited, thus making it possible to reduce the heating thereof. in the case of clinkers.
  • the plate being a foundry piece, it requires only a minimum of machining operations and, moreover, without modification of its already advantageous structure and its four-point support mode, it can be molded in any thickness variable to choose between a low value e (figure 4) and a higher value E (figure 6).
