Description

APPARATUS AND METHOD FOR EXTRACTING MAGNETICALLY SUSCEPTIBLE MATERIALS FROM A FLUID This invention relates to an apparatus and method for the extraction of magnetically susceptible materials from a fluid, and particularly, but not exclusively, to an apparatus and method for the extraction of mill scale from water.
Various apparatus and methods are known for the extraction of magnetically susceptible materials from a fluid. These include magnetic filters used for the extraction of fine particles of iron contamination and iron oxide from ceramic slip or glaze and chemical/industrial slurries.
These comprise a non-magnetic housing surrounded by an electromagnet.
A matrix of magnetisable elements is placed inside the housing and when the magnet is activated the elements become magnetised. Fluid containing magnetically susceptible material is passed into the housing, where the material is drawn to and retained on the magnetised elements. The remaining, clean fluid is then discharged into a holding tank. To remove the magnetically susceptible material, the magnet is de-activated releasing the material which is flushed out of the housing using water. To remove the magnetically susceptible material requires a disruption in the fluid cleaning process, which can be undesirable.
In another area, i.e. the continuous casting and hot rolling of steel products water is generally sprayed through nozzles onto the steel to cool it. This water is usually re-cycled and each time it is used and re-used it picks up particles of iron mill scale. If these are not removed from the water they result in blockage of the nozzles. The mill scale is conventionally removed by first discharging the water into one or more settling tanks, where some of the mill scale settles at the bottom of the tanks. The remaining water is then passed through one or more pressurised sand filters. Settling tanks can be expensive to operate and maintain, and can take up a considerable amount of space. In addition, they require periodic emptying and removal of the mill scale which can be costly in both time and effort. This also interrupts the process of removing the millscale from the water. It would clearly be of benefit to provide a method and apparatus for removing mill scale from cooling water which does not require the use of such tanks.
According to a first aspect of the present invention there is provided an apparatus for removing magnetically susceptible materials from a fluid, the apparatus comprising a housing fabricated of one or more non-magnetic materials, and having inlet means for introducing the fluid into the housing, separating means comprising a plurality of magnets placed in proximity to the housing which, in use, are operated to cause at least some of the magnetically susceptible material to migrate to and along the periphery of the housing to a chosen position of the housing, and outlet means for discharging from the housing the fluid from which at least some of the magnetically susceptible material has been separated.
The housing is fabricated from a non-magnetic material in order that it does not prevent the magnets from creating a sufficiently high magnetic field within the fluid to act upon the magnetically susceptible material. The housing could, for example, be fabricated from nonmagnetic stainless steel.
Means may be provided for discharging the magnetically susceptible material from the housing. The magnetically susceptible material may be discharged from the housing from the chosen position.
The magnetically susceptible material may be continuously discharged from the housing. Alternatively, the material may be allowed to accumulate in the housing over a period of time, and be discharged after that time.
The magnets may be permanent magnets and may be operated to cause migration of the magnetically susceptible material by removal of the effect of one or more of the magnets on the material. This may be achieved by removal of the one or more magnets from the vicinity of the housing.
The magnets may be temporary magnets such as electromagnets activated by the supply of an electric current thereto. The magnitude of the electric currents supplied to the electromagnets, which determines the strength of the magnetic field created within the fluid, is preferably adjustable, and may range from zero to a maximum level. This adjustment preferably takes place throughout the operation of the apparatus to achieve continuous migration of the magnetically susceptible material to the periphery of the housing. The magnitude of the or each electric current may be so adjusted by automatic control means, or manually.
The magnets may be positioned alongside a portion of the housing, or may surround a portion of the housing.
The magnets, when temporary magnets, may be activated and/or de-activated simultaneously, or may activated and/or de-activated at different times. Control means may be provided to control the sequence of activation and/or de-activation of the temporary magnets. The control means may comprise a programmable logic control. The temporary magnets may be so arranged relative to the housing that sequential activation and de-activation thereof causes migration of the magnetically susceptible material along the periphery of the housing to the chosen position of the housing. The magnets may be activated and de-activated successively.
The housing may comprise a tank, which may be provided with an inlet pipe for introducing the fluid into the tank, and an outlet pipe for discharging the fluid from the tank. Means may be provided for discharging the magnetically susceptible material, together with a portion of the fluid, from the tank. This could be a further outlet pipe.
In a preferred embodiment, the housing comprises a tube or generally U-shaped channel such as a pipeline, duct or flume. The fluid containing the magnetically susceptible material preferably flows continuously through the tube or channel, at a speed of, for example, 1 m/s. Preferably six temporary magnets are provided. When the housing comprises a tube, each magnet is preferably toroidal and is located so as to surround a portion of the tube. When the housing comprises a channel, the magnets may be arranged in two rows, one row being disposed alongside one arm of the channel, the other row being disposed alongside the other arm of the channel. The magnets may be each be shaped as a yoke.
The tube or channel is preferably provided with an outlet for the discharge of the magnetically susceptible material therefrom. The outlet may comprise a pipe through which magnetically susceptible material, together with a portion of the fluid, is discharged. An eddy chamber may be provided in proximity to the outlet pipe which causes eddy currents in the fluid in the tube or channel. These produce hydraulic forces which aid the discharge of the magnetically susceptible material. The magnets may be activated and de-activated sequentially to cause the magnetically susceptible material to migrate towards the outlet.
A non-magnetic baffle may be provided within the tube or channel.
This is preferably elongate and positioned co-axially of the tube or channel. This has the effect of deflecting the fluid containing the magnetically susceptible material towards the periphery of the tube or channel. The position of the baffle within the tube or channel may preferably be capable of radial or axial variation.
According to a second aspect of the present invention there is provided a method of removing magnetically susceptible material from a fluid by means of apparatus according to the first aspect of the invention, the method comprising the steps of: (i) introducing the fluid into the housing; (ii) operating the magnets to cause at least some of the magnetically susceptible material to migrate to and along the periphery of the housing to a chosen position in the housing; and (iii) discharging the fluid, from which at least some of the magnetically susceptible material has been separated, from the housing.
The method may comprise the further step of discharging the magnetically susceptible material from the housing.
Preferably the flow of fluid through the housing is continuous.
Preferably the magnets are operated sequentially to cause the magnetically susceptible material to migrate along the periphery of the housing to the chosen position, from where the material may be discharged from the housing.
An embodiment of the present invention will now be described by way of example only, with reference to the accompanying drawing which is a longitudinal section through an apparatus according to the first aspect of the present invention.
The drawing shows a housing comprising a tube 1 having an inlet end 2 and an outlet end 3. The diameter of the tube is increased along a portion of its length to form an eddy chamber 4. An outlet pipe 5 communicates with the eddy chamber. A baffle 6 is provided co-axially within the tube 1, and is held in place by supports 7A and 7B. Six magnets, 8 to 13, are placed in succession along and in proximity to the tube. Each magnet is toroidal and surrounds a portion of the tube. Each magnet includes an electromagnetic coil to which an electric current is supplied. Activation and de-activation of the magnets is controlled by a programmable logic control (not shown).
In use, fluid containing magnetically susceptible material is introduced into the tube 1 via the inlet end 2. The fluid flows through the tube and is discharged therefrom via the outlet end 3. As the fluid flows through the tube it encounters the baffle 6 which deflects the fluid towards the periphery of the tube. During flow of the fluid, all the magnets are first activated whereby at least some of the magnetically susceptible material migrates to the periphery of the tube. Magnet 8 is then deactivated, releasing the material proximal to that magnet. The material which is released is acted upon by the magnetic field created by magnet 9 and migrates to the periphery of the tube proximal to magnet 9. Thus the magnetically susceptible material is caused to migrate along the tube from a position proximal to magnet 8 to a position proximal to magnet 9.
Magnet 9 is then de-activated and the magnetically susceptible material migrates to a position along the tube proximal to magnet 10. The remaining magnets 10 to 12 are each de-activated in turn, until the magnetically susceptible material has migrated to a position along the tube proximal to magnet 13. This magnet is then de-activated and the magnetically susceptible material is swept by the fluid into the eddy chamber 4. Eddy currents are set up in the eddy chamber by the passage of the fluid. These, and the position of the magnetically susceptible material around the periphery of the tube, cause the magnetically susceptible material, together with a portion of the fluid, to be discharged from the tube via the outlet pipe 5. The remainder of the fluid, from which some of the magnetically susceptible material has been removed, is discharged from the tube via the outlet end 3.
