MAXIVIBE
Features
-
Designed for low volume type
applications, MAXIVIBE can filter a wide
variety of dusts, and can adapt to different situations without the
need for compressed air for cleaning.
-
Solid construction using 12
and 16 ga steel sheet with adequate reinforcement, the cabinet is
capable of withstanding 15 in. w.g. of negative pressure.
-
A high quality finish made
possible by a coating procedure in 3 stages, starting with a
phosphatised surface preparation, followed by a polyurethane primer
and a polyurethane top coat of light industrial gray very resistant
to rust.
-
Complete cleaning by manual
or automatic shaking; the automatic shaking is programmed to last
from 35 to 60 seconds after each unit stoppage. The shaker control
panel includes the fan contactor.
-
Direct drive blower mounted
directly in the cabinet with a high efficiency TEFC motor. The
backward inclined centrifugal blower is spark proof and is capable
of moving the air silently without maintenance.
-
Five models are available
and cabinets can be paired to increase capacity.
-
The support structure is
available in 3 arrangements.
MAXIVIBE
Operation
During operation, dust-laden
air enters the dust collector from the top of the hopper, the dusty
air will first contact a deflector plate forcing the larger particles
down into the dust box, and the air velocity is also reduced in this
section. The fine remaining dust is then carried upwards into the
envelope filter and forced through the tissue, depositing it’s dust on
the dirty side of the filter and forming the “dust cake.”
The now cleaned air is drawn
into the backward inclined impeller and is then exhausted outside the
collector. The “dust cake” formed on the dirty side of the filter can
be dislodged by a manual shaking system or by an automatic filter
shaking mechanism.
Automatic Shaking Mechanism
When the unit is stopped, a
control system composed of a timer relay will be energized, after 30
seconds of settling, the shaker motor will come into action, providing
a shaking action transmitted through a shaker bar to the envelope
filter, the “dust cake” is then broken and the dust falls into the
hopper section.
After the shaking sequence has
stopped, another timer will provide another settling time of 45
seconds before the unit may be turned on again for another filtering
cycle.
The manual shaker comes
standard with the collector; the automatic shaking system is
optional.
Specifications
Construction
The cabinet and the hopper are
built of 12 and 16 gal steel sheets, reinforced with folded channel
sections, providing a strong and rigid cabinet. The hopper section is
bolted to the cabinet and a large service door is provided at the
front of the casing for easy envelope filter service.
Paint Finish
After completion and before
final assembly, all components are treated with a phosphate-based
coat, which degreases and treats the metal. The cabinet is then
primed with an epoxy-based undercoat and furnished with a highly
resistant gray epoxy finish that is resistant to scratching, chipping,
and fading. The Maxivibe collector is then assembled and tested
before shipping.
Filter Assembly
The filter assembly consists
of several inverted “V” shaped pockets stitched into a single filter
element. The inlet of the filter element is held at the base on an
angle frame and the shaker bar frame, which in turn is held in
position in sleeve bearings on either side of the collector, supports
each top of the “V”.
Filter Materials
The standard filter material
is non-woven polyester felt for better dust release; this provides
high filtering efficiency at low-pressure drops. Other fabrics such
as nylon, Terylene, P.T.F.E. and flame retardant coatings are
available.
Blower Assembly
The B.I. type impeller is
directly attached to a high efficiency TEFC motor mounted on the top
of the collector, the centrifugal blower is installed inside the
cabinet and is made of non sparking glass reinforced polyamide
ensuring maximum performance.
Controls
The standard Maxivibe dust
collector comes equipped with a manual shaker and does not require any
controls other than a starter for the motor. When an automatic
shaking system is ordered, a control panel is furnished. This control
panel includes the magnetic starters for the blower motor and for the
shaker motor, a control transformer and timed relays are preconnected
and ready for installation. A remote start / stop switch is available
when the dust collector must be started from a distance. All motors
are TEFC type and can be ordered explosion proof.
Selection
Maxivibe dust collectors are
selected by applying the adequate air / cloth ratio. After having
properly determined the air volume required to rid the production
machines of the dust they produce, the air to cloth ratio is selected
based on the type of dust and the concentration of the dust. Dividing
the air volume by the a/c ratio will produce a surface area
corresponding to the required tissue area needed to adequately filter
the dust without blinding the filter.
