Introduction:
Magnetic
Filter is used for filtration of iron particles from products in liquid form.
They are also frequently used in hydraulic circuits in cooling systems. Magnetic
system is made up of either Ceramic or High intensity Rare Earth magnets. The
Magnet unit is enclosed in stainless steel housing making it suitable for use
in Chemical, Paper & Ceramic Industry.
The
Magnetic Filter is easily removable from the stainless steel enclosure by
loosening a few quick release fasteners. For the removal of fine magnetic
particles or oxidized iron particles, normally system with High Intensity Rare
Earth Magnets is recommended.
The
unit comprises of a vessel, magnetic lid assembly with fasteners that secures
the unit together.
Magnetic
filters are widely used for filtration of fine ferrous impurities in variety of
industries like:
·
Lubricants
·
Coolants
·
Hydraulic
oils
·
Slurries
·
Liquid
Chemicals
·
Liquid Food
products
How does it work?
Magnetic
filters
are installed at a suitable
location along the passage of fluid. The flowing liquid is made to travel
around magnetic field of high intensity Magnetic Elements where fine ferrous
particles get arrested.
These
arrested fine iron particles can be removed manually after removing the top lid
of the filter. Drain plug is provided at the bottom face for periodical
cleaning of the filter system.
Construction:
Manual Cleaning Filters
Magnetic
filters are made up of Stainless Steel 304
/ 316 shell with inlet and outlet
flange connections and a drain plug. The filters are made up of high intensity
permanent magnets (Ndfeb) made in the form of elements. These magnetic elements
are fixed on the top lid and are arranged in circular format so that the liquid
is exposed to maximum area of elements.
Once the
fluid is passes through the filter, iron contamination gets arrested on the
elements. This is removed manually after removing the top lid of the filter.
Self Cleaning Filters
The self
cleaning filters consist of sleeves provided over the elements. The iron
particles get trapped over the sleeve when the fluid is passed through the
filter. When the elements are removed along with the top lid, the iron
particles get dropped from the sleeve on the bottom of the filter which is
removed through the drain plug by injecting pressurized water.
