Description

SYSTEM AND METHOD FOR CLEANING A SCREEN
Technical Field
This invention relates to a system and a method for cleaning a screen.
Background Art
The use of screens, having apertures of a fixed size for
sorting/separating particles by size and/or de-watering slurries and/or
screening out trash or oversize particles, is widely known.
Considerable problems are experienced with blinding of apertures of
these screens, as a result of the lodging of particles in the apertures,
and consequently reducing their effectiveness.
It is accordingly an object of this invention to provide a system and a
method for de-blinding a screen.
Disclosure of the Invention
According to a first aspect of the invention, there is provided a system
for cleaning a screen, having multiple apertures, the system
characterised by including at least one high pressure nozzle unit, having a nozzle, capable of generating an ultrasonically stimulated,
high velocity fluid jet, the nozzle unit being positioned operatively
relative to a screen to direct the fluid at the apertures to dislodge the
particles blinding the apertures during a screening process.
The nozzle may be a rotating nozzle, capable of rotating about an axis
at an angle to the screen.
The nozzle unit may be movable relative to the surface of the screen.
Preferably, the nozzle unit is movable in an oscillatory manner
substantially across the screen.
The nozzle may have a diameter of between 0.3 mm and 1.5 mm and
preferably between 0.889 mm and 1.143 mm.
The nozzle unit may be of the type made available to the South
African market under the names "Kranzel Dirt Killer", "Kranzel
Turbo Killer", or a nozzle unit similar thereto. The fluid supplied to the nozzle may at a pressure between 0.1 and 12
MPa. The pressure may be constant, alternatively pulsating.
The fluid may be supplied to the nozzle at a flow rate of between 8
litres/min and 15 litres/min and preferably 12 litres/min.
The nozzle unit may be mounted on a spray bar. The spray bar may
be in the form of a pipe, having an opening communicating fluidly
with the nozzle unit. The spray bar may be suspended operatively
above the screen and movable in a plane, extending substantially
parallel to the screen, so as to render the nozzle capable of directing
the jet at adjacent apertures across the screen.
The spray bar may be spaced above the screen such that the nozzle is
at least one complete ultrasonic wavelength, alternatively, multiples
of complete wavelengths from the screen. Preferably, the spray bar
may be spaced above the screen such that the nozzle is between
200mm and 500 mm, and more preferably 340 mm, from the screen. The spray bar may be suspendable between tensioned cables, fixed
rails, chains, or some other suitable mechanical suspending device
and moved by manipulation of this device. The spray bar may be
provided with a number of nozzle units, the spray bar serving as a
manifold.
The rotation of the nozzle may result in a circular sprayed zone,
having a diameter at the screen of approximately 160 mm.
The screen may include a number of screening panels .
According to a second aspect of the invention, there is provided a
method for cleaning a screen for particulate material, the method
including the steps of spraying an ultrasonically stimulated fluid jet at
a screen; rotating the jet about an axis at an angle to the screen; and
moving the jet substantially across the surface of the screen to
dislodge particles blinding apertures during a screening process. Brief Description of the Drawings
The invention will now be described by way of non-limiting example
only, with reference to the accompanying drawing illustrating a
perspective view of a system for cleaning a screening panel in
accordance with the invention.
Best Mode of Carrying Out the Invention
A system (1) for cleaning a screen (2), in accordance with the
invention, is illustrated in the accompanying drawing. The system (1)
includes two nozzle units (3), the nozzle units (3) being supplied with
high-pressured fluid by means of a supply pipe (4). The nozzle units
(3) are capable of generating an ultrasonically stimulated, high
velocity fluid jet (5). The nozzle units (3) are positioned so as in
operation to direct the jet (5) at the apertures of the screen (2), so as to
dislodge particles blinding the apertures during a screening operation. The nozzle units (3) each include a rotating nozzle (not shown),
which rotates about an axis (7) at an angle to the screen.
The nozzle units (3) are of the type available to the South African
market under the name "Kranzel Turbo Killer" or "Kranzel Dirt
Killer".
The nozzle (not shown) has a diameter of between 0.889 mm and
1.143 mm.
The fluid is supplied to the nozzle at a pressure between 0.1 and 12
MPa. The pressure is constant.
It is however envisaged that the pressure could be pulsating, typically
generated as a result of pressure fluctuations associated with the use
of certain types of pumps.
The fluid is supplied to the nozzle at a flow rate of about 121itres/min. The nozzle units (3) are mounted on a spray bar (8) in the form of a
pipe, having corresponding openings communicating fluidly with the
nozzle units. The spray bar (8) serves as a manifold to the nozzle
units (3).
The spray bar (8) is suspended above and movable in a plane,
extending substantially parallel to the screen (2), so as to render the
nozzles capable of directing the jets at adjacent apertures across the
screen.
The spray bar (8) is suspended between a support-and-movement
mechanism (9), and is moved by manipulation of this mechanism. It
is envisaged that this mechanism (9) could be tensioned cables or
chains.
The spray bar (8) is spaced from the screen (2) such that the distance
between the nozzle and the screen is one complete ultrasonic
wavelength, or about 340 mm from the screen or alternatively,
multiples of complete wavelengths from the screen. With the nozzles (not shown) mounted at the desired distance of one
wavelength or about 340 mm from the screen (2), the rotation of the
nozzles results in sprayed zones having diameters (10) at the screen
(2) of approximately 160 mm. It is envisaged that, to cover the full
width of some screens with the spray bar moving in a linear fashion
along the length the screen, it would be necessary to have multiple
nozzle units (3) mounted to the spray bar.
It is envisaged that the movement created by the mechanical
suspension device could also be from side to side.
Many screens in use consist of a number of screening panels.
In use, the force of the jets (5), combined with the pulsating effect
produced by the pump (not shown), and depending on the nozzles
used, the ultrasonic velocity of the jets, dislodges particles blinding
the apertures of the screen (2). It is envisaged that in an alternative embodiment, the screen could
move in an oscillatory manner relative to a substantially stationary
nozzle unit.
It will be appreciated that numerous embodiments of the invention
could be performed without departing from the scope of the invention
as defined in the claims below.
