Definitions
- the present invention relates to high-intensity magnetic separators working in the wet and consisting of at least one separation chamber traversed from top to bottom by the product to be treated, in the form of a liquid or pulp containing in suspension the particles to be separated, and magnets or coils creating in the chamber a magnetic field whose lines of force are perpendicular to the direction of flow of the product to be treated;
- the separation chamber may contain a matrix formed of grooved plates, balls, expanded metal, iron wool, etc. through which the product to be treated circulates.
- Separators of this type with discontinuous operation have a cyclical operation: in a first phase, the product to be treated is circulated in the separation chamber in the presence of the magnetic field; during this phase, the magnetic constituents of the product are fixed on the walls of the chamber and / or on the elements of the matrix, while the non-magnetic particles are entrained by the liquid phase of the product and collected in a first collector.
- the supply of the product to be treated is cut off, the magnetic field is removed and the magnetic products are extracted from the separation chamber by washing using a pressurized liquid which is generally water.
- a pressurized liquid which is generally water.
- the object of the present invention is to allow the use of permanent magnets, in place of electromagnets, in high intensity magnetic separators working in wet conditions and, by this means, of reducing the weight, the bulk and the cost of these devices and reduce their energy consumption.
- the magnets can be moved by means of cylinders controlled by a programmable automaton, at the same time as valves placed on the supply and the evacuation of the separation chamber, to be applied on the walls of the chamber during the separation phase and be removed from them during the evacuation phase of the magnetic constituents, the duration of each of the phases being predetermined or a function, for example, of the degree of clogging of the chamber.
- the separation chamber can be constituted, in a conventional manner, by a tubular casing made of non-magnetic material, containing a matrix formed of grooved plates, balls, expanded metal, etc., and occupying the entire section of the chamber.
- the magnets can be formed by an assembly of elementary magnets whose direction of magnetization is perpendicular to the direction of flow of the product treated in the separation chamber. It is also possible to use a stack of magnets and flat pole pieces, the direction of magnetization of the magnets being in this case parallel to the direction of flow of the product to be treated.
- the pole pieces located on either side of the separation chamber may be located in the same plane perpendicular to the direction of flow of the product to be treated and with the same polarity or opposite polarities, or vertically offset by half not.
- the separator has only one separation chamber, its operation is necessarily discontinuous.
- several identical elementary units will be combined, each unit being formed by a separation chamber, permanent magnets, possibly pole pieces, and means for removing the permanent magnets from the chamber and applying them to its walls, and being supplied cyclically with products to be treated and washing liquid, the various units being successively supplied so as to allow continuous operation.
- the different units can be fixed and be connected, on the one hand, to a supply of products to be treated and to a collector of purified products and, on the other hand, to a source of a washing liquid and to a collector of magnetic constituents, through a set of valves whose opening and closing are programmed to ensure cyclic operation of the separation units.
- the separation units can also be mobile and movable between a separation zone, which is equipped with means for supplying products to be treated, and for collecting purified products, and a washing zone provided with means for distributing a liquid. washing and collecting magnetic components.
- a separation zone which is equipped with means for supplying products to be treated, and for collecting purified products
- a washing zone provided with means for distributing a liquid. washing and collecting magnetic components.
- the movement may be alternative.
- the separation units will be linked to each other to form an endless ring or chain and will be moved step by step, always in the same direction. We can obviously provide, several separation and washing zones, along the ring or the endless chain.
- the longitudinal movement of the units will be accompanied by a transverse displacement of the magnets when the units pass from one zone to another.
- each unit could comprise two or more chambers which would be brought successively between the magnets, in a separation zone comprising, moreover, means for supplying the product to be treated and for collecting the purified product, then distant from this zone and brought to a washing area equipped with means for dispensing a washing liquid and for collecting magnetic constituents, the magnets normally applied to the walls of the chamber being in the separation zone, being periodically spaced apart to allow the chambers to be moved.
- the magnets and / or the pole pieces located on either side of the separation chamber being of opposite polarities, the means used to separate them from the separation chamber must overcome the force of magnetic attraction. Part of the energy involved can be recovered during the movement of magnets or pole pieces, especially when using several units operating sequentially.
- the separation unit shown in FIGS. 1 and 2 essentially consists of a separation chamber 10 placed between two permanent magnets 12 of opposite polarities. Each magnet is integral with an L-section armature 14, the two armatures forming a closed magnetic circuit with the magnets and the chamber 10, when the magnets are applied to the opposite walls of the chamber 10, as shown in the figure. 2 a.
- the separation chamber consists of an envelope made of a non-magnetic material, of rectangular section and open at its two ends. It is filled with grooved vertical plates or other elements, such as bars, steel wool, etc ... made of soft magnetic material which create in the gap magnetic field gradients allowing the magnetic particles of the product to be treated to fix on said elements.
- the chamber 10 is connected to a pipe for supplying the product to be treated 16, through a solenoid valve 18, and to a pipe for pressurized water 20, through a solenoid valve 22.
- a collector 24 is placed under the chamber 10 and connected to two conduits 26 and 28, through solenoid valves 30 and 32, respectively, which make it possible to direct the products collected in two different directions.
- Cylinders 34 make it possible to move the magnets and the armatures perpendicular to the large faces of the chamber 10 and to maintain the magnets applied to the latter (FIG. 2 a) or separated from them (FIG. 2 b).
- This separation unit operates as follows: in a first phase, the magnets 12 are applied to the large faces of the chamber 10 (FIG. 2 a), the valves 18 and 30 are open and the valves 22 and 32 are closed.
- the product to be treated, in the form of pulp flows from top to bottom in the chamber 10, between the vertical plates.
- the magnetic particles are subjected to attractive forces which deflect them towards the plates and hold them there.
- the purified product is collected in the collector 24 and evacuated through the conduit 26.
- the magnets are moved away from the chamber (FIG. 2 b), the valves 18 and 30 are closed and the valves 22 and 32 are open.
- the magnetic particles which are no longer subjected to the action of the magnetic field are then entrained by the pressurized water circulating in the chamber 10 and discharged through the conduit 28.
- the duration of the first phase can be predetermined, in particular if the content of the product to be treated in particles magnetic changes little over time.
- the transition from the first to the second phase can be done when the degree of clogging of the chamber, evaluated for example from a measurement of the flow rate or of the pressure drop, reaches a predetermined value.
- the magnets must be separated by a sufficient distance so that the magnetic field in the chamber 10 is practically zero, the lines of force of the magnetic field of each magnet then closing in on themselves through the air gap formed between the magnet and chamber 10 and the associated armature.
- the magnets 12 are constituted by an assembly by bonding of elementary magnets with samarium-cobalt or with neodymium-iron-boron, the direction of magnetization being perpendicular to the large faces of the chamber 10.
- each magnet 12-armature assembly 14 could be replaced by a stack of magnets 40 and pole pieces 42, as shown in FIG. 4, the direction of magnetization of the magnets being parallel to the direction of flow of the product to be treated in the chamber 10 (arrow F ).
- Figures 3 a and b show another embodiment of the separation chamber.
- This is here constituted by an elastically deformable tube 110, made of rubber or plastic, which normally has a circular section (FIG. 3 b) and takes a flattened shape. when it is compressed between the magnets 12 ( Figure 3 a).
- the tube will be filled with a material, such as steel wool, which can be compressed elastically without great effort so as not to hinder the deformation of the tube and its return to the original shape.
- Wires of soft magnetic material arranged longitudinally or braided to form a tubular sheath could be embedded in the thickness of the wall of the tube to create magnetic field gradients on the inside of the tube.
- Figure 3a corresponds to the separation phase, the magnets being brought together and crushing the tube 110; in the washing phase ( Figure 3 b) the magnets are spaced from each other, and the tube has resumed its circular shape.
- FIG. 5 The diagram of such an installation is shown in FIG. 5.
- the supply lines for the product to be treated 16 and for pressurized water 20 are connected to the chambers 10 ′ and 10 ⁇ through solenoid valves 18 ′ and 18 ⁇ and 22 ′ and 22 ⁇ , respectively.
- Collectors 24 ′ and 24 ⁇ placed under the chambers 10 ′ and 10 ⁇ make it possible to direct the products leaving the chambers towards an outlet for purified product or an outlet for magnetic product, depending on the position of a schematic selector by a pivoting flap 50 ′, 50 ⁇ .
- valves 18 ′, 18 ⁇ , 22 ′ and 22 ⁇ , the selectors 50 ′ and 50 ⁇ as well as the jacks, not shown, moving the magnets 12 ′, 12 ⁇ are controlled by a programmable controller or a microcomputer according to a pre-established and modifiable program so that at least one of the units is in the separation phase at all times.
- the number of units to be used in an installation will depend on the flow of product to be treated.
- the use of standard units saves costs and facilitates maintenance, as a faulty unit can be quickly replaced by a spare unit.
- An intermediate rinsing phase with maintenance of the magnetic field may be provided to remove the grains of non-magnetic constituents retained by magnetic flocculation.
