English Abstract




A fluorescent lamp and high intensity discharge lamp recycling machine
comprises a
stainless steel casing which can be divided into an upper, central and lower
zone. The
upper zone is made up of a gravity fed chute that accepts the lamps. At the
bottom of the
chute is an electrically driven six bladed stainless steel breaking wheel.
This are is
constantly saturated with water using spray jets. The central zone has a
stainless steel
basket which catches broken glass and allows water, mercury and phosphor to
fall into
the lower zone. The lower zone has a hopper to collect the water, mercury and
phosphor.
A water pump draws the contaminated water into a centrifuge which separates
the
mercury from the water. The water then passes through a water filter and is
then sent
back up to the spray nozzles in the upper zone.

CA 02547624 2006-05-16
Patent Application for:

Fluorescent lamp and High Intensity Discharge Lamp recycling machine.

This machine (1) has a stainless steel tube structure with stainless steel
outer skin
measuring 2134 mm long x 1874mm tall x 762mm wide. The feed chute (5) is also
made
of stainless steel with an opening measuring 237mm x 616mm. Lamps are fed into
the
feed chute (5). Gravity pulls the lamps down to a six blade stainless steel
breaking wheel
(3) which is driven by an electric motor (4). The broken lamp particles,
mercury and
phosphor then drop into a removable stainless steel basket with a perforated
mesh bottom
(12). The aforementioned areas are constantly saturated with cold water
through wide
spray nozzles (13). There are sixteen nozzles in total. The glass and end caps
remain in
the stainless steel basket (12) while the water, mercury and phosphor pass
throughthe
stainless steel basket (12) and fall into a water filled hopper (2). This
hopper(2) is filled
by attaching an external garden hose and volume is controlled by a brass
floatation
Switch (11) which stops the flow of water coming from the external garden
hose,
preventing overflow. The water is then drawn out of the hopper (2) by a]
10volt water
pump (10). The water pump (10) then pushes the mercury and phosphor
contaminated
water into a centrifuge (6). Mercury is heavier than water. Once the
centrifuge (6) is full
of mercury in the bottow., a ball valve (8) can be opened and the centrifuge
(6) can be
drained through a flexible hose (9) into a receptacle designed to transport
mercury. The
rest of the remaining phosphor contaminated water is then pushed through the
upper side
of the centrifuge (6) and into a 5 micron water filter (7). The filtered water
is then
circulated back up to the spray nozzles (13) and reused.
