Definitions
- TITLE Device for separating granulometric selective solid powdery materials, centrifugal action, and method of using such a device.
- the present invention relates to a device for separating granulometric selective solid pulverulent materials, centrifugal action, and a method of using such a device.
- This type of device makes it possible to separate a stream of particles present in a stream of gas in two fractions, one fine smaller than a given particle size, the other coarse larger than said particle size.
- Such a device is also referred to in the corresponding industrial environment "Centrifugal air selector".
- the separation is carried out using a cylindrical rotor with vertical axis, provided with blades regularly distributed on its periphery, and between which the particles are subjected to antagonistic forces, namely, on the one hand, the centrifugal force generated by the rotation of the rotor and which tends to reject them, and secondly, the drag force generated by the speed of a gas sucked towards the center of the rotor, and which tends to drive with him towards the exit of said gas .
- the centrifugal force is higher for the larger sized particles and the higher drag force for the smaller sized particles, which achieves granulometric selection of the treated materials.
- Substances having dimensions smaller than a determined selection particle size are thus entrained with the gas towards the outlet of said gas, while the materials with dimensions greater than said determined particle size fall back and are collected in a gravitational manner.
- the feed of the materials to be treated can be carried out both by the upper part in a gravitational manner, in which case the materials are generally dispersed by a rotating plate integral with the rotor, or a suspension in the incoming gas, or by combining the two previous feeding modes.
- the collection of materials whose dimensions are greater than the determined grain size of selection is carried out via an inverted cone-shaped hopper, located under the rotor.
- the walls of the hopper must have a significant slope relative to the horizontal, generally 50 to 60 °, to ensure the gravity flow of the materials towards the outlet, at the tip of the cone. This slope determines the height of the conical hopper, which constitutes a substantial part of the height of the complete apparatus. The height of this hopper can not be reduced and may pose problems of integration in some facilities.
- this lower hopper requires to provide motorization of the rotor at the top of the device.
- the gas outlet is immediately followed by a bend in order to position the rotor motor above this elbow.
- This configuration however requires to provide the rotation shaft connecting the motor and the rotor of sufficient length to be able to cross the elbow. Inside this bend, the rotation shaft must be protected by a sheath whose outer coating, specific, must resist abrasion.
- Document GB 943722 discloses a prior-generation selector capable of separating pulverulent materials into two fractions, one of fine particle size, the other of coarse particle size, and teaching a collection of materials by means of a bed collection system. fluidized, low slope, to reduce the height of the device.
- Another disadvantage of this type of apparatus is that the separation between the grains of smaller and larger dimensions is not perfect, a portion of the fine grains, less than said determined particle size, falling with the larger grains in the hopper.
- the rate of said fine grains rejected with the coarse materials is commonly called “selection bypass” and constitutes an imperfection.
- This imperfection can be the result of a group effect, the fine grains, attached to larger grains, being rejected by the rotor, thus falling in the hopper, or even a poor supply of powdery materials in the device.
- the object of the present invention is to overcome all or part of the aforementioned drawbacks.
- the object of the present invention is to provide such a device, or even a method, for reducing the selection bypass, namely the rate of fines rejected with coarse materials.
- Another object of the present invention may be to propose a size separation device of limited size in height.
- Another object of the present invention may be to provide such a device whose rotor motor architecture is substantially simplified.
- the invention firstly relates to a device for separating granulometric particles of solid powdery materials, with centrifugal action, capable of separating the materials into two fractions, a fraction of fine materials and a fraction of coarse materials, comprising:
- a cylindrical rotor rotatable relative to said casing along a vertical axis, internal to said casing, provided with blades distributed over the periphery of said rotor,
- said collection means comprise a fluidized bed peripheral system, the bed of which extends around the axis of said cylindrical rotor, at least below said vanes and in the space between said vanes and said rotor, the velocity of the fluidizing gas in a horizontal section of the fluidized bed being less than 1 m / s so as to produce a new separation between the fines and the coarse materials for which said fines are returned to the gap between said blades and said rotor.
- the invention also relates to a method of using a granulometric separation device according to the invention in which a fraction of pulverulent material is introduced into said envelope between the blades and the rotor of the device and is divided, of a on the other hand, in a fraction of fine material, of particle size smaller than a determined particle size, entrained by said gaseous flow returning through the rotor towards the outlet, in particular an upper outlet, of the device and, on the other hand, in a coarse fraction, of dimension of particles greater than said determined particle size, rejected by the rotor to said means for collecting the device, in which method the average velocity of fluidization air is determined in a horizontal section of the fluidized bed less than 1 m / second and in such a way as to minimize in the discharges the rate of particles smaller than said determined particle size.
