Abstract

The magnetic separator 20 comprises an outer annular frame member 22 which is arranged to arranged to retain a plurality of linear magnetic rods 24 in order to provide a magnetic array or grid through which processing materials must pass. The frame member 22 comprises a strong, lightweight hollow annular member with a hollow shaped cross section formed from formed strip material and is arranged to removeably retain the linear magnetic rods 24 thereto by means of fasteners 26. The magnetic rods 24 can be independently removed and replaced and the annular frame member 22 comprises a static dissipative material e.g. stainless steel and can be vibrated. An extend portion 32 of the frame shields the connection area. The relatively strong and lightweight frame material allows the circumference of the material pathway through the magnetic separator 20 to be relatively large compared to the outer dimensions of the magnetic separator. The separator can be used in the food industry and the pharmaceutical industry in order to remove magnetic contaminants from a material, and is of particular use in potentially explosive atmospheres, for example as found in flourmills.

Description

MAGNETIC SEPARATOR
Field of the Invention
The present invention relates to magnetic separators and specifically to vibrating sieve magnets In particular, the present invention relates to improvements in the construction of vibrating sieve magnets for use in the food industry including the pharmaceutical industry.
Background to the Invention
Magnetic separators and magnetic separator components are used for the removal of magnetic and para-magnetic contamination from solids, liquids, granulates and powders. The aims of such separators include the protection of production machinery, prevention of production line stoppages and ensuring that the final product is free of contamination and specifically is free of ferrous contaminants.
The reduction or elimination of contaminants in the food industry is critical. In addition, the reduction or elimination of contaminants in the pharmaceutical industry may be essential. Accordingly, magnetic separators are frequently used in the food industry (including the pharmaceutical industry) in order to remove contaminants from a processing material used in the production line.
At present, a known separator or sieve comprises a number of parallel linear magnetic rods wherein the ends of the magnetic rods are encapsulated by a circular outer annular frame such that the linear magnetic rods extend across the central opening of the frame. The outer annular frame comprises a moulded plastics, and in particular, comprises a cast epoxy plastic having a circular outer profile and a hexagonal inner profile, as shown in figure 1 and figure 2. The outer frame member is solid in order to provide the necessary strength in retaining the parallel magnetic rods 14 and in particular, provides strength to retain the parallel magnetic rods 14 during vibration of the sieve.
As shown in figure 1 and figure 2. The prior art sieve 10 comprises an outer frame member 12 comprising an epoxy plastic which retains a number of parallel magnetic rods 14. However, the plastic retaining frame member 12 is hard and brittle and, therefore, is prone to fatigue cracking. In addition, the rods 14 become loose and vibrate within the plastic frame member 12 which causes hygienic and structural problems. Specifically, any fractures or cracks within the frame 12 may harbor bacteria which is a significant risk and hazard in the food and pharmaceutical industry.
An alternative separator, particularly used in the pharmaceutical industry, comprised a solid stainless steel outer frame member which is intensively machined and fabricated to encapsulate the ends of stainless clad magnetic rods.
However, such separators are very heavy and expensive to manufacture. The mass of the outer frame member generates high momentum and inertia forces when induced with high frequency oscillations from the vibratory sieve and can be prone to cause subsequent damage to the grids integrity, magnetic performance and sieve integrity If part of the sieve/separator fails or fractures then this requires the sieve/separator to be replaced. This can cause a significant loss in time and production.
The outer frame member of the prior art sieve/separator has an outer circular profile and an inner hexagonal profile. Since the frame member comprises a plastics then the dimensions and, in particular, the width of the annulus is significant. This, therefore, restricts and reduces the circumference or size of the inner, profile which defines the flow pathway through which the material flows through the separator. This thereby limits the speed of flow of the material through the separator.
Furthermore, the plastic material in prior art separators is not static dissipative and this poses the significant risk of an accumulation of static which thereby poses an explosive risk. Explosive atmospheres in the workplace can be caused by flammable gases, mists or vapours or by combustible dust. If there is enough of the substance, mixed with air, then it only requires a source of ignition to cause an explosion. Static electricity can provide such a source of ignition. The present invention aims to provide a separator in accordance with the ATEX framework for controlling explosive atmospheres and the standards of equipment and protective systems used in them.
It is an aim of the present invention to overcome at least one problem associated with the prior art whether referred to herein or otherwise.

Description of the preferred embodiments
As previously explained, magnetic separators located in separating apparatus are frequently used in the food industry including the pharmaceutical industry, for example, bakeries may use separating apparatus to extract magnetic contaminants from flour (or other ingredients) during the baking process. The uses may also include, but not limited to, the use in flourmills, bakeries, pharmaceutical production systems and chemical production systems. The separator may also help to size and break up the material and/or restrict the flow and processing of relatively large lumps of material.
The separator apparatus includes an inflow region (for example, a hopper) in to which the flour is poured. The flour then passes through the magnetic separator where magnetic contaminants are extracted. The flour then flows through an outflow region into the processing apparatus. For example, 25 kg bags of flour may be poured into the hopper in order to be initially screened and cleaned prior to the baking process.
The magnetic separator 20 comprises an outer frame member 22 which is arranged to retain a plurality of magnetic members 24, as shown in figure 3 to figure 6. In use, the magnetic separator 20 is located in separating apparatus (not shown). In use, material is arranged to pass through the separating apparatus in order for magnetic contaminants to be extracted from the material. In particular, the magnetic separator 20 is for use in the food and pharmaceutical industries.
Contamination such as rust, stainless steel scrapings and wear from machinery are often too small to be detected by a metal detector but is easily removed by the present invention. The material flows through the magnetic grid and any contamination is immediately attracted to the powerful magnetic rods. The contamination is pushed to the undersides of the rods, where it is securely held, out of the way of the wash-off effects of continuous material flow. The grid requires no power and no maintenance (except for cleaning) and is quick and easy to install. The strength of the magnetic rods can be selected for either coarse ferrous contamination or for micron sized ferrous contamination and para-magnetic contamination.
The outer frame member 22 comprises a static dissipative material in order to conduct static through it. This prevents the problem of static building up in the material which is hazardous particular in an environment which may include a dusty atmosphere or other potentially hazardous atmosphere for example, potentially explosive atmospheres. In particular, the material comprises food quality 316 grade stainless steel and is fully sealed.
The magnetic separator 20 provides a material flow pathway which is defined by an inner periphery 23 of the annular member 22 of the magnetic separator 20.
The inner periphery 23 provides a circular periphery to the flow pathway which the material is arranged to pass through.
The magnetic separator 20 comprises a plurality of magnetic members 24 which are retained to the annular frame member 22. The magnetic members 24 provide a grid which enables the material to pass therethrough. As the material passes through the grid, contaminants which are attracted to the magnetic members 24 are extracted by the capture of the contaminants by the magnetic members 24. After use, once the material has passed through the magnetic separators 20, the magnetic rods 24 may be cleaned to remove the contaminants and the magnetic separators 20 can then be reused.
The magnetic members 24 comprise magnetic rods 24 which are retained in the magnetic separator 20 by engagement means 26 which releasably engage the magnetic rods 24 to the annular frame member 22. The magnetic rods 24 comprise linear magnetic rods 24 having engagement means at each longitudinal end thereof. Accordingly, the magnetic rods 24 can be easily be removed and replaced within the magnetic separator 20. In particular, each magnetic rod 24 is quick and independently removeable and replaceable.
The engagement members 26 comprise couplings and specifically screw members in which a first part 28 or first portion of the engagement member 26 is provided on the annular frame member 22 and a second part 30 or second portion is provided on the longitudinal ends of the magnetic members 24.
The annular frame member 22 comprises a cross section which is uniform about the circumference of the annular frame member 22. The cross sectional profile comprises a strip which is bent or otherwise shaped to provide the cross section. In particular, the annular frame members 22 essentially comprises an extrusion which is formed into an annulus or ring.
The annular frame member 22 comprises deflection means and in particular a deflection surface 32 which is arranged to deflect or shroud the engagement members 28, 30 and/or the longitudinal ends of the magnetic members 24 from direct impact as the material flows into the separation apparatus. In particular, this arrangement or configuration ensures that all of the material flows in between two adjacent magnetic members 24 and the material is not able to flow through a pathway adjacent to the longitudinal ends of the magnetic members 24 where the
magnetic field may be relatively weak.
As shown in figure 6, the cross-section of the annular frame member 22 comprises a hollow tube 34 or box section. The cross-section also comprises the upper deflection surface. The corners of the annular frame member are rounded in order to prevent the corners from piercing/rupturing or otherwise damaging a resilient rubber seal which is arranged, in use, to locate over the outer surfaces of the annular frame member 22. The seal is arranged to seal the magnetic separator 20 into the separating apparatus. In particular, the separating apparatus comprises a clamping mechanism to clamp the magnetic separator 20 in the separating apparatus.
The annular frame member 22 comprises a strip of material which is shaped to provide a strong lightweight outer frame rnember The strip extends across a lateral extent of the annular frame member to form the shaped cross-sectional profile whilst the strip extends longitudinally to form a circumferential annular frame member.
The strip comprises a strip of stainless steel which is formed into the required shape by any suitable methods.
In the preferred embodiment, the strip is shaped to provide a tube section 34 which may have a continuous circumference or contiguous surface. This tube 34 provides a retaining section in which first portions 28 of engagements members are located. The hollow tube 34 provides a relatively low mass which increases the life span and durability of the apparatus.
The annular frame member 22 is constructed of a thin wall hollow stainless steel outer ring resulting in a low overall weight for the grid therefore reducing the manual handling hazard presented to a technician fitting and cleaning the grid.
The slim profile outer ring presents a more open magnetic area product flow resulting in an overall improved magnetic performances.
The construction of the present invention significantly reduces the manufacturing cost enabling a current pharmaceutical standard grid to now be commercially available to the food industry.
In addition, in the present invention, all materials used are static dissipative to allow the product to be used in "ATEX" environments.
The low overall mass of the present invention reduces the momentum and inertia forces thereby reducing sieve, housing, seal and magnetic deterioration.
The present invention thereby has increased reliability with respect to prior art magnetic separators.
The present invention does not include small parts which can be misplaced, lost or inadvertently separated.
The present invention is particularly for use in explosive atmospheres in the workplace caused by flammable gases, mists or vapours or by combustible dusts.
In particular, the present invention is designed for use in accordance with the DSEAR and ATEX framework for controlling explosive atmospheres and the standard of equipment and protective systems used therein.
