Washer Vario Split for ash removal

Washer Vario split

The Washer Vario Split is a machine for
washing fibre stock suspensions in the low density
range, i.e. for removing finest particles such as
e.g. ash and inactive fines as well as printing

ink particles detached from the fibre up to a grain
size of 30 – 40 pm. The long and short fibre content
is thereby increased in comparison to the composition
of the stock fed in. At the same time, thickening of
the fibre stock suspension takes place. At inlet
stock consistencies of 0.4 – 1.3 %, outlet stock con—
sistencies up to lo % are reached, depending on type
of stock and operating conditions.

Principle

The low density suspension supplied is distributed
by two distribution pipes uniformly onto the fish—
tail dies of the headboxes and sprayed into the
wedges between the turning wire and the central
rolls. Due to the one-sided dewatering between cen—
tral rolls and wire, a fibre web is formed which
runs along with the central roll and which is
picked—up by a doctor. The filtrate is collected

in a collecting tray and discharged.

Design of the machine

The frame is made up of MSH—hollow sections and
connected with cross beams. The construction ele—
ments are carried by foundation rails. The head—
boxes are screwed onto the frame.

The central rolls and all other lead rolls are pro—
vided with a rubber cover and supported on the frame.
The individual rolls are cleaned by means of doctors.
Two sticky doctors can be provided for cleaning the
central rolls.

The wire is tensioned via pneumatic cylinders. The
wire tension, which can be set according to the dia—
gram, must not exceed 7 N/mm. During wire change,
the roll automatically moves to run-in position when
the air pressure is removed.

For wire regulation, a guide roll is controlled by a
pneumatically working controller, for which special
instructions are enclosed.

When changing the rolls in the machine, they must be
placed on a roll board and removed from the machine.

For dismounting the lower central roll, an I—profile has
to be mounted in front of the roll, via which the roll
can be removed from the machine. The support under the
roll is removed simultaneously.
