PART 2 GENERAL OVERVIEW
Just above the pulper discharge and drain assem-
bly is the recirculation pump, which moves the ex-
tracted water back to the feed trough reuse. Note
that this feature greatly reduces water usage. At
the discharge of the recirculation pump, there is an
adjustable gate valve. This valve is set at installa-
tion to balance level between pulper and extractor
and should only be adjusted by qualified mainte-
nance technicians.
Cutting Mechanism
The Insinger pulper is designed with a first class
cutting mechanism for improved waste processing
and reduced maintenance. The hardened stainless
steel cutting blocks can be rotated to get twice the
life before replacement. Also, both the stationary
cutting blocks and those attached to the impeller
are replaceable with a single allen wrench – without
removing the impeller.
The drive motor is vertically mounted to the under-
side of the slurry chamber and is held in place with
four stainless screws. The stainless motor shaft
protrudes through the impeller and is bolted directly
to a retainer plate. Between the impeller and the
machined tank bottom is a removable magnetic
seal that prevents the slurry liquid from leaking out
of the tank. On the bottom side of the impeller are
the pumping vanes which are bolted in place for
easy replacement. Surrounding the impeller is a
perforated stainless security ring which ensures
only small particles can pass through to the extrac-
tor in the slurry.
Piping
Water level is controlled by an engineered system
of solenoid valves, flow controls, and a level switch.
The heart of the water system on the pulper is the
recirculation pump, which re-uses water removed
from the slurry in the extractor and returns it to the
feed trough. A gate valve located downstream of
the pump allows flow adjustment to create balance
between the level in the pulper and extractor.
This slurry is passed to the extractor where the ro-
tating screw conveys the solid waste vertically. The
screw is surrounded by a perforated stainless
screen which allows the water to be separated and
recirculated to the pulper. Solid waste is forced
upwards by the screw and forms a semi-dry pulp at
the entrance to the compression area. Water is
then further extracted in this compression zone. As
the pulp enters the discharge area it is called a
plug. As the plug enters the top of the extractor, it
is broken down by a cutter attached to the rotating
screw. This action allows the semi-dry pulp to be
easily discharged into a waste receptacle.
Pulper
The Insinger Eliminator is the latest in pulping tech-
nology with many innovations for improved opera-
tion, maintenance and cleaning. Some of these
include: NSF clearance above the floor, full vibra-
tion isolation system, true one-piece tank, inte-
grated tubular support frame, adjustable feed
trough and lid orientations, reduced overall height
and cutting mechanism upgrades.
The pulper tank housing includes the trough flange,
lid and water feed connection. At the base of the
tank is the slurry chamber and precision cutting
mechanism. Mounted to the bottom of this cham-
ber is the single drive motor. This one-piece
stainless tank serves as the main structure with a
latchable top lid.
The entire structure is designed with full shrouding
of the electrical and piping, including the drive mo-
tor. This polished stainless housing is supported
on the integrated tubular framing and tied to the
one-piece tank for stability. Just downstream of the
pulper discharge the two removable side covers are
mounted to the frame. They support the piping in-
cluding the customer water and electrical connec-
tions.
