LAUNDRY ADVANCED SYSTEM
EQUIPMENT DESCRIPTION AND DATA -- Continued
The washing/drying system contains two washing/drying drums. Each drum is capable of washing, rinsing, extracting,
and drying 190 -- 200 pounds of laundry per hour. Each drum is independently mounted to the LADS frame with four
air bags and four shock absorbers. The air bags and shock absorbers reduce the amount of vibration that is
transferred to the LADS structure when the drum(s) is rotating. Each drum consists of an outer shell which supports
the basket, drive motor, brake, dryer ducting, blower, and front door. The basket consists of a metal housing with four
flights that contain and distribute the laundry as it is rotated. The basket and outer edge of the flights are perforated to
allow hot drying air to flow onto the laundry. The basket is connected to a drive shaft that is attached to the drum
housing with two pillow block bearings. This shaft is rotated by an electric motor that is connected to the shaft with
two sheaves and a drive belt. The shaft also contains a brake rotor that is mounted between an air brake. Laundry is
loaded into the drum through the see--thru front door. The door contains a lock that prevents it from being opened
while the basket is rotating.
Air used to dry the laundry is provided to each drum by independent electric blowers. A protective screen is located at
the fresh air inlet to each blower. These screens prevent debris (sand, dirt, leaves, etc.) from entering the dryer
ducting. A lint filter is used in the air recirculation path for each blower. These filters remove lint and other particles
from the air that is circulating from the drum back to the blower. The screens and filters are easily removed and are
reusable after cleaning.
The LADS contains five water tanks. Each washing/drying drum has a wash tank and a rinse 1 tank. These tanks
have a 70 gallon capacity. The rinse 2 tank has a 140 gallon capacity and is shared by both drums. Each tank has a
sight glass that provides a visual indication to the operator that the tank is full. Pumps and valves are used to control
the flow of water between the tanks and drums. Pumps are also provided to control the delivery of detergent from the
external supply container to the drums.
