Definitions

  • the present invention relates to a helical vibrating lifting device and its use for effecting an effective separation between spherical particles and non-spherical particles, for example for separating balls of neighboring sizes, some being round, the others being broken (broken).
  • This invention possibly coupled with separation by screening, makes it possible in particular to restore to refiners or petrochemicals batches of inert perfectly calibrated beads.
  • the device according to the invention can be used for other applications, for example, for separating the shell grains in the food industry or for separating spherical catalysts from poorly formed spheres.
  • the apparatus makes it possible to carry out the separation of spherical materials according to their size as well as the separation of the spheres and of the fragments of spheres which will be called hereinafter "broken".
  • the system according to the invention makes it possible to exclude broken grains from a mixture of spherical or ovoid products and, for example, to eliminate broken ceramic beads in beds of inert beads which refiners have in hydrotreatment reactors which allows, after sorting, to restore a batch of inert balls perfectly calibrated and therefore reusable with an efficiency equal to that of new materials.
  • the apparatus according to the invention is of the helical vibrating lift type; it consists of at least one substantially horizontal turn (substantially vertical axis) whose width is between approximately 50 and 400mm and preferably between 200 and 300mm with a pitch (distance between the tops of two turns) from 50 to 150mm, and preferably of the order of 80 to 120mm, for example around 100mm.
  • the slope is from 2 to 20 degrees approximately and preferably from 9 to 16 degrees.
  • the turn or each turn, if there are several, has 2 to 9 steps or more for example up to 150 steps by way of example and is wound around a hollow barrel at the base or at the top of which, for example, systems are arranged allowing the barrel-turn assembly to take a vibratory movement of variable amplitude.
  • the vibrations can be produced by at least one system placed at any suitable level, for example at the base or at the top of the barrel or else positioned around the coil.
  • the unbalance motors the electro-magnetic vibrators (excited by a variable cycle, with creation of pulses), and the unbalance exciters.
  • the amplitude (lateral) of the vibration movement thus communicated to the assembly can thus vary between 0.2 and 15mm and preferably between 2 and 5.5mm.
  • the barrel-turn assembly, source of vibration could be arranged, for example, on a central post serving as support, various anti-vibration materials which can be interposed between the barrel and the post.
  • the material used for making the coil, or more exactly the steps of the coil may be a blasted mild steel, or a stainless steel, etc., coated with an anti-rust paint.
  • modifying the coating of the pitch that is to say, for example, by spraying a plastic paint or by sticking a rubber band, or any other suitable material, it is possible on the one hand to modify the coefficient of adhesion and, therefore, the segregation of powdery products for a given amplitude, but also considerably reduce the noise caused by the movements of balls on the steel.
  • Figure 1 there is shown a barrel or post (7) with a turn (4) to 5 steps, such as (5).
  • the unbalance motor (6) generates vibrations around the axis or post.
  • the flow of the mixture of beads to be separated or of beads and broken pieces to be separated is introduced via the pipe. 1 into the periphery of the coil, in a step between the upper step and the lower step, and for example in a step located halfway up the coil.
  • the solid particles will thus circulate on the band of the turn or circulation band of the step, this circulation band being delimited by the internal and external edges of each step.
  • the larger balls they descend along the whorl, with a speed which accelerates so that under the effect of centrifugal force, the large balls roll more and more on the periphery of the whorl, c that is to say mainly between the outer edges of the circulation band of each step and said middle part of the step. Therefore, gradually and without hindering, the balls descend along the outer edges of the steps of the turn against small beads or broken pieces that travel from bottom to top, along the inner edges of the steps of the turn.
  • the vibration system is subject to an appropriate adjustment depending on the nature and dimensions of the particles to be withdrawn.
  • the small balls or the broken pieces are evacuated at the top by the pipe 3, the balls of the desired size being recovered by the pipe 2 at the bottom of the turn.
  • FIG. 1 shows the apparatus of Figure 1, seen from above.
  • Each of these 3 types of particles represents 1/3 by volume of the total mixture.
  • the amplitude of the vibrations was adjusted to 2mm: it was observed that the breaks are animated by a vibration movement such that, by successive micro-projection on the step, they rise in the coil and leave the coil via the conduit 3 while the balls of diameters 2.54cm and 1.27cm descend downwards or remain in the lower part of the coil, and end up being evacuated through the conduit 2.
