A portable unitary apparatus, preferably wheeled, is provided herein for disposing of hazardous light bulbs, e.g., fluorescent light bulbs. The apparatus is in the form of a housing which includes an upper compartment, and a lower compartment. The top of the housing is provided with a cylindrical fluorescent light bulb feed chute for a fluorescent light bulb to be disposed of. A rotary, bulb crushing fluorescent light bulb device, comprising a pair of rigid articulated crushing hammers is secured to opposed ends of a securement member, by means of a chain-type joint, each rigid articulated crushing hammer including an arm and a weighted end, the weighted end being secured to the end of an associated arm by a chain-type joint. The rigid articulated crushing hammers which are powered by a motor, are disposed within an enclosed reduction chamber shroud which depends from the upper compartment. A disposable, pulverized fluorescent light bulb collection bag is selectively disposed within the lower compartment in air-sealed relationship to the reduction chamber. A filter system is disposed within the upper chamber. This filter system includes exhaust tubes which are connected between the reduction chamber and the fluorescent light bulb feed chute, and is constructed to draw noxious vapors through three filters arranged in series by means of a vacuum generator. The vapors pass through primary, secondary and tertiary filters and then into the reduction chamber shroud, where a portion of the vapors is recycled through the filters again, while the rest of the vapors accompany the disintegrated glass into the disposable bag. Thus, any trace amount of vapors which may be discharged into the ambient environment are environmentally-clean. A weigh scale means may also be provided to prevent overfilling of the disposable bags.
In an apparatus for the disposal of fluorescent light bulbs including a chute for feeding fluorescent light bulbs into a sealed fluorescent light bulb crushing or disintegration shroud, a filter system to prevent discharge of toxic vapors to the atmosphere, and disposable means for collecting crushed fluorescent light bulbs, the improved fluorescent light bulb crushing system comprising:
