Plasma & laser cutting ash extraction equipment of metal processing
Integrated ash extraction system advantages
Remote linkage function
The central fume purification system has power socket and plug of
EU standard.
When the purification system is installed outdoors or in other
places, an additional control terminal can be installed at a
convenient place, or a control panel whose functions are the same
with those of the control panel of the purification system can be
connected to through a modem. That is easy to operate and saves
power consumption as well.
Intelligent control
The central fume purification system is controlled by PLC control
system. All of operations control and information display are on
the control panel with control button and display screen, the
operation screen is humanization design and the operating is very
convenient.
Our engineers can set the running program according to the
requirement of different working conditions, for instance the
automatically cleaning ash times after starting and stopping the
equipment. Setting up the reverse blow cleaning’s technical
parameters according to the on-site air environment, fume &
dust characters and compressed air supplying.
The controlling system implements real time monitoring and analyzes
on a number of important parameters of the equipment in operation,
and show them on the display screen. It has automatically
self-diagnosis function to show the equipment’s abnormal and error
conditions in operation. These functions can make the equipment in
good working condition and extend the usage life of the equipment.
Surface filtration precision
The functionality of an extractor lies in the filter cartridge’s
material, Kaisen has been dedicating to upgrading filter cartridge.
Kaisen filter element is specially developed for the purification
of fume and tiny particles generated in welding and cutting, which
solved this industry’s problem of low filtration precision and
filter element’s blocking. Kaisen filter cartridge uses polyester
fibers (glass fiber) material, and with a special heat process the
outer surface of the cartridge is covered with a layer of PTFE
(polytetrafluorethylene) membrane. The filter cartridge’s interior
wall is thin and firm, the surface membrane has very even pores,
and form a network of pores’ of diameter less than 0.1μm.
In order to increase filtration area, all of filters are folded in
“v” shape, the folding angle is sharp, so no dusts will be retained
in the “V” shaped folds when the vertically placed filter cartridge
is blow-cleaned. Dusts directly fall into the dust collector below
and won’t cause interactive pollution.
Reverse blow cleaning
Rotary dust blowing device is inserted inside the filter cartridge
and very close to the cartridge’s inner wall. When the solenoid
valve opens, compressed air rush into two pipes drilled with
nozzles, implementing rotary blowing to clean every part of the
filter cartridge. Compared with externally placed blowing nozzles,
rotary dust blowing nozzles’ blow force is even on every part of
the cartridge, and have a thorough cleaning to avoid big noise and
damage to the cartridge caused by instant huge blow impact of the
externally placed blowing method.
Dust cleaning
Dusts fall directly into the dust collector below after treated by
central fume extractor. Kaisen central fume extractor adopts
pneumatic or mechanical lifting. Stop the machine to remove dusts
regularly, open pneumatic control valve or wind the mechanical
handle, dust collector will fall slowly to carry or pull it outside
to dump the dusts. If the machine can’t stop, a flash board can be
inserted on the dust collector, to avoid dust escape while removing
dusts. To prevent dusts secondary pollution, Kaisen dust collector
is complete with flame-retardant garage bag, to make dust removing
easier.
Equipment maintenance
As purification equipment is closely related to environment and
human health, its regular inspection, maintenance and the file
recording must be done in accordance with relevant law.
