Definitions

  • the present invention relates to a sieving device intended, more particularly but not exclusively, for sieving flour mixtures such as those used for human or animal food.
  • 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 screened is poured, said grid being subjected to vibrations which cause advance the product from the upper end of the grid to its lower end. During this progression the fine particles cross the grid.
  • the present invention which overcomes this drawback, is remarkable in that the grid assumes the shape of a truncated cone, the small base of which, which is situated downwards, is connected to a discharge pipe and in that the product to be screened is poured out at the periphery of the upper part of the grid, the assembly being agitated so that the particles to be screened tend to rotate around circumferences of small diameter.
  • a frustoconical surface Under the grid is arranged a frustoconical surface whose small base, directed downwards, is connected to a discharge pipe.
  • the grid Above the grid is disposed a cone, the top of which is directed upwards and the diameter of the base of which is less than the large diameter of said grid.
  • This member makes it possible to distribute the product to be screened at the periphery of the grid.
  • the device consists of an envelope 1, forming the body of the device and having an 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 of non-rigid elements.
  • a grid 3 affecting the shape of a truncated cone whose small base is directed downwards.
  • the central part of the grid is connected, via a funnel 4, to a pipe 5 through which the particles which have not passed through the grid 3 are discharged.
  • the particles, which have passed through the grid, are collected on a frustoconical surface 6 whose small base, which extends downwards, is connected to a discharge pipe 7.
  • the surface 6 can advantageously be constituted by the lower part body 1.
  • Means are provided for agitating the body 1, such as, for example, an unbalance motor 8 which communicates to the particles to be screened a circular movement, said particles tending to rotate according to circumferences of small diameter.
  • an unbalance motor 8 which communicates to the particles to be screened a circular movement, said particles tending to rotate according to circumferences of small diameter.
  • means are provided for pouring the product to be screened at the periphery of the grid 3.
  • a cone 9 is used, placed above the grid 3 and the diameter of the base of which is less than the large diameter of said grid.
  • the cone 9 may have means for distributing the product and guiding it.
  • Such means can be constituted by ribs, such as that 10, arranged along the generatrices of the 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 an end piece 12 which is axially movable and which is connected to the pipe 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.
