Environmentally Friendly Operation
The Tiegel Wash Maxi II Model 94 Washer-Dryer will rinse, wash and dry
4,000-5,000 batteries per eight hours using just 20-50 gallons (190 liters)
of water. This is being filtered through a 2 micron filter and can be utilized
for acid cutting. In addition, substantial amounts of soap are saved since
soap is not required to neutralize the acid. This machine is divided into
three sections: the pre-wash rinse section, the main wash section and the
drying section. Each of these is a fully automatic, micro-processor controlled
function. All you need is soap, fresh water, and caustic (sodium hydroxide)
and your dirty batteries. Our machine does the rest.
Three Sections of Machine
- Pre-wash Rinse
The Pre-wash Rinse Stations remove over 99% of the battery acid. Since
the rinse water is highly filtered, the flow has the ability to be used
for cutting acid. Because of the small quantity, de-ionized water can be
considered, thus recycling 99% of the recovered acid. A sump pump below
the rinse section intermittently feeds the acidified water to your acid
- Main Wash
In the Main Wash Section, the water is kept crystal clear, salt-free
and acid-free by the use of a cartridge particulate filter and Acid Sponge
Resin bed. This unique system allows any soap required to be chosen for
its cleansing properties rather than for neutralization of the acid. The
water is heated to 80-100° F (26-43° C) to assure optimum grease
removal and is controlled by a thermostat. By containing the water evaporation,
we substantially reduce the energy required to heat the water. Four soft
cloth brushes remove any insoluble dirt on all sides of the battery including
the front and end panels. A pH meter controls the acidity of the rinse and
wash water, and indicates when it is time to regenerate the acid sponge
resin. If the pH drops below the pre-set level, the machine will warn the
operator, who then has approximately 8 hours before the acidity of the wash
water becomes excessive for normal operations. The machine will shut down
if the pH drops too low for safe operation. Regeneration of the acid-sponge
resin bed is fully automatic, and takes approximately 1-1/2 hours. Less
than 1/2 gallon of 50% caustic is used per regeneration cycle. If a 24-hour
operation is required, we can offer an automatic regeneration, Option B,
which requires no shut-down.
The final section of the machine is the Drying Section which consists
of three high pressure blow-off stations. These stations are highly effective
in removing over 99% of the remaining water droplets on typical automotive
battery types with clear surfaces. The drying nozzles are adjustable, both
in position and flow rate, to obtain optimum drying conditions. Since the
wash water is salt and dirt free, no water spots can form on the batteries.
Improved End-Product Appearance
Since end product quality is the real issue, we have designed our battery
washer to eliminate the problem areas. Our washer produces squeaky clean
batteries with no salt spots or wipe down required. In the field, this washer
produces batteries that are so clean that one of our customers is placing
them into a 1000 volt DC cabinet with no arcing problems.
- Acid-Free, Clean, Dry Batteries
The Tiegel Battery Washer-Dryer Model 94 has been designed to wash and
dry batteries in the most efficient way possible. Two pre-wash rinse stations
strip 99% of the acid from the batteries, producing a flow of .1 GPM (.38
LPM) containing up to 5% acid. This water is then passed through an acid-proof
polyester cartridge filter which removes any impurities down to 2 microns,
and allows unregulated disposal into your electrolyte cutting operation.
The remaining 1% of the acid is removed in the wash area, where the wash
water is again filtered before being recycled through our unique Acid Sponge
(ion exchange resin) bed. Regeneration of the resin bed is required after
approximately 80 hours of operation and is initiated by a signal from a
pH controller. Once begun, this process is 100% automatic. Four multi-directional
soft cloth floppy brushes gently remove all dirt and grease from the top
and four sides of the batteries (especially front and rear panels). The
dry section contains three high pressure blow-off stations which effectively
strip all water from the surface of the battery. No set-up is required for
different battery types. A top blow-off station accommodates all battery
heights. Because of our digital pH meter control, we have eliminated the
chance of any battery leaving the washer with acid contamination.
- Automatic, Easy Maintenance Conveyor Belt
Incoming conveyor speed is 8 - 12 feet per minute (2.5 - 3.7 meters/minute);
batteries are automatically spaced with a built-in differential conveyor
belt speed, allowing a thorough washing and drying of all battery surfaces.
We use a high quality PVC sticky top belt to prevent battery slippage and
tracking is automatic due to our unique v-belt design. In addition, we have
close-coupled our conveyor drive, eliminating high maintenance drive belts
and external drive chains.
- Energy Conscious, Safer Operation
Our washer is self-contained, using only 12.5kW. Since the operation
is all electrical; we have eliminated the problems normally associated with
combustion systems, such as flame safety issues and exhaust ventilation
requirements, since no carbon monoxide is present. Additionally, a digital
display thermostat control provides quick and easy wash water temperature
adjustment with built-in safety interlocks to prevent the thermal run-away.
The machine is programmed for automatic start-up and shuts down automatically
to stand by when the last battery has left the machine. This feature saves
10.2 kW per hour in stand-by mode while keeping the water hot for immediate
Maintenance Made Easy
Our battery washer is constructed of all corrosion-proof materials including
a type 316L stainless steel frame and enclosure, and PVC plumbing. All filters
are cartridge type and can be replaced in under five minutes. The Acid Sponge
resin bed has been designed to facilitate maintenance and is readily accessible.
Accessibility is readily available from top to bottom. The Washer's top
cover is readily removable, allowing easy access into the machine. Similarly,
all major components may be removed for servicing while the machine is still
in operation. For this, ball valves and unions have been provided.
