Definitions

  • the present invention relates to a screening device intended, more particularly but not exclusively, for sieving flour mixes such as those used for food human or animal.
  • such a device is constituted, in its simplest form, by a grid, rectangular and inclined, at the upper part of which the product to be sieved is poured, said grid being subjected to vibrations which advance the product of the high end of the grid at its low end. During this progression fine particles pass through the grid.
  • Document DE-A-4210770 discloses a sieving device comprising a body, capable of being agitated, containing a grid affecting the shape of a truncated cone whose small base, which is connected to a funnel connected to an evacuation pipe, is directed downwards, at the the periphery of which screens the product to be screened is poured out.
  • Such a device requires changing the grid if desired modify the particle size of the sieved product.
  • the present invention which remedies this drawback is remarkable in that the device comprises several superimposed grids and in that the funnel is made integral with an axially movable nozzle and connected to the evacuation pipe.
  • the device consists an envelope 1, forming the body of the device and having a opening 2 at its upper part to allow the introduction of the product to be sieved.
  • the body 1 is suspended, for example, under a loading hopper by means non-rigid elements.
  • a grid 3 affecting the shape of a trunk of cone, the small base of which is directed downwards.
  • the central part of the grid is connected, through a funnel 4, to a pipe 5 through which the particles are discharged who have not crossed the gate 3.
  • the particles, which have passed through the grid, are collected on a frustoconical surface 6 whose small base, which extends downward, is connected to a discharge pipe 7.
  • the surface 6 can advantageously be constituted by the lower part of the body 1.
  • Means are provided for agitating the body 1, such as, for example example, an unbalance motor 8 which communicates to the particles at sieving in a circular motion, said particles tending to turn around small diameter circumferences.
  • an unbalance motor 8 which communicates to the particles at sieving in a circular motion, said particles tending to turn around small diameter circumferences.
  • Means are provided for discharging the product to be screened at the periphery of the grid 3.
  • a cone 9 is used, placed above the grid 3 and whose diameter of the base is less than the large diameter of said wire rack.
  • the cone 9 may have means for distributing the product and guide him.
  • Such means may consist of ribs, such as that 10, arranged along the generatrices cone 9.
  • the body 1 contains several grids such as those 11 a , 11 b and 11 c , identical to that 3.
  • the lower grid has a mesh whose diameter is less than that of the mesh of the upper grid.
  • the funnel 4 for receiving particles which have not passed through the grid, is carried by a tip 12 axially movable and connecting to line 5.
  • the mobile assembly 4-12 is arranged to receive the particles which have not passed through the grid 11b .
  • the particles which will have crossed the lower grid 11 c will be collected by the surface 6 and evacuated by the pipe 7.
  • the particles which cannot cross the grid 11 c will also be collected by the pipe 7 after having crossed the annular space 13 formed between the lower part of the grid 11c and the end piece 12.
