PART 2 GENERAL OVERVIEW
Control Logic Description
The pulper power is applied by pulling out the
ESTOP buttons. Turn the START/STOP switch to
ON. Limit switches and Overloads are checked
and if they are OK, CR1 is energized (pulled in)
passing power to the fill circuit. SOL1 power is ap-
plied until level is met and the time delay T1 has
passed. When level switch is made, CR2 relay en-
ergizes passing power to the run circuit. The op-
erator must press the START pushbutton to pull in
the pump and press extractor motor starters. The
Normally Open (NO) contact on M1 seals the run
circuit and M2 (pulper motor) contactor energizes.
The system should now be running.
If any motor overload is tripped, CR1 drops out,
stopping the entire system by dropping out CR2.
When the Overload is reset, CR1 pulls in allowing
the fill circuit to restart and automatically fill if
needed. The operator must wait until the fill cycle
is completed then press the START push button to
run the motors.
During running, SOL2 is energized, allowing water
to flow to the seal flush and to the pulper refresh at
approximately 1 to 2 gallons per minute. When the
level drops in the extractor for time delay T1, SOL1
is energized for quick fill.
When the selector switch is turned to OFF, timer T2
is energized and as long as M1 was already ener-
gized, (the system is already running), SOL3 is en-
ergized. Thus the extractor spray down cycle be-
gins. For time delay T2 (approximately 5 minutes)
the pulper will continue to run while spraying hot
water on the extractor screen. At the end of the
time delay, the system stops because T2 contacts
change state.
At start-up, the pulper fills to the level determined
by the switch in the extractor. When the pulper first
starts, water is pulled by the recirculation pump into
the feed lines and trough. If water level drops be-
low that set by the switch, the fast feed solenoid
turns on to quickly restore system balance. To
keep the pulping system clean and free of odor a
small amount of fresh water is constantly intro-
duced to the system by the refresh solenoid. This
solenoid also provides the water flush for the mag-
netic seal, which helps seal longevity by eliminating
build-up of pulped material.
Extractor
The Insinger Eliminator, close-coupled pulping
system includes an innovative water extractor that
makes cleaning and maintenance easier. One of
the key design attributes is the bottom mounted
drive for simple screw and screen removal from the
top. Other improved functionality includes adjust-
able discharge locations, full NSF clearance AFF,
and round tank with standard spray system for
easier cleaning.
The slurry input chamber forms the base for the
extractor, with the one inch thick machined plate as
both a gear box support and seal housing. The au-
ger screw is centered in the input chamber and
rides on a bottom bearing. The rolled stainless tank
houses the extractor screen and auger. A latchable
side door creates easy access to the tank internals,
including the spray cleaning system and overflow
drain. At the top of the tank is the compression
chamber, where the “plug” of semi-dry waste enters
the discharge chute and is broken down by the plug
cutter. The discharge chute has an access door
with draw latch and limit switch for controlled ac-
cess to the top of the extractor.
