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.
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.
Description
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.
