CZ1552U1 - Apparatus for destruction and classification of linear fluorescent lamps - Google Patents

Description

, Tech Field}

The technical solution concerns equipment for destruction and sorting of linear fluorescent lamps in production and amortization sphere.

BACKGROUND OF THE INVENTION

Tubular fluorescent lamps are widely used in lighting production halls, hospitals, schools, etc. Because these lamps contain mercury, they become hazardous waste at the end of their useful life, which can only be disposed of by deposited in landfills or by treatment or recycling. the low-mercury components are separated and possibly used as secondary raw materials and the high-mercury components are demerkurised.

Recycling technologies used in the world can be divided into two types. According to a first procedure, the lamps are crushed and subsequently sorted into glass, metal products and a phosphor containing most of the mercury. The crushing and screening process is carried out either in a dry state in a vacuum system spoj coupled to a two stage cleaning system. gas or wet during internal water circulation. According to the second procedure, the destruction of the lamps is controlled in order to obtain some components, such as sockets, during the destruction. Separation of the bases from the tubes is usually done by heating and cooling the glass locally at the bases. However, these devices are unable to separate other components, such as metal shutters, lead glass of the inner cup, glass at the end of the tube containing generally increased mercury.

The essence of the technical solution

To a large extent, the apparatus for the destruction and sorting of linear fluorescent lamps according to the present invention is characterized by the fact that it consists of a feed table and a set of driving wheels, which are supported at both ends of the shaft and have circumferential cuts and hooks . Furthermore, it consists of a lever knife supplemented with an additional hammer, and in the space between the driving wheels is a groove to which the outlet trough is connected and another groove to which the other outlet trough is connected. The distance between the driving wheels on the axis is

- 2 adjustable depending on the length of the linear fluorescent lamps and on the length of the filament parts of the linear fluorescent lamps,

Linear fluorescent lamps on the feeding table are removed by means of hooks into the grooves on the driving wheels. In a certain position of the driving wheels, the lever knives cut off at both ends of the linear lamp lamps which slide through the groove located between the driving wheels into the exit trough outside the device. Lever knives are equipped with an additional hammer, which together with the base cut off from the end of the lamp several centimeters of glass, which is usually contaminated with mercury. This contaminated glass, together with the inner cup, metal orifice, wires and tungsten spiral, falls into another groove located between the drive wheels and further into the second outlet groove outside the device. The separated parts of the linear fluorescent tubes are processed separately including the central part of the linear fluorescent tubes, which are processed by standard magnetic separation, crushing and further separation on vibrating and rotary screens etc. and the resulting material is processed eg by demerkurization or represents secondary raw materials.

- 3Example embodiment

The device according to FIGS. 1 and 2 consists of a feeding table 4 and a set of driving wheels 1 mounted on both ends of the shaft 2, which are circumferentially provided with cut-outs 5 and hooks 2, further a lever knife supplemented with an additional hammer 2. A groove 7 is provided in the wheel 1, which opens into the outlet trough 8 and a groove 10 which opens into the outlet trough H. The distance between the driving wheels. adjustable on the axisLT depending on the length of the linear fluorescent lamps and the length of the fluorescent parts of the linear fluorescent lamps.

The function of the device for destruction and sorting of linear fluorescent lamps is shown in Figures 1 and 2.

The linear fluorescent lamps on the counter table 4 are removed; in using the hook 3 to ixty / II pinch wheels ³³ i. At a certain position of the flanged wheels 1 £ retort lever knives on both sides of fluorescent lamps bases that slide groove 7 positioned between the engaging wheels 1 into the discharge chute £ outside the device. Auxiliary hammer 2 complementing the lever knives; at the same time as the lamp bases, the mercury-polluted portion of the linear fluorescent tube 'cuts off from the end of the lamps and, together with the inner cup, metal orifice, wires' and tungsten spiral, falls into the trough 10 and into the outlet trough H away from the device. The separated parts of the linear fluorescent lamps are processed separately including the central part of the linear fluorescent lamps, which are processed by standard magnetic separation, crushing and other separation on vibrating and rotary screens etc. and the resulting material is processed eg by demerkurization or alternatively represents secondary raw materials.
