Abstract
Description
Die Erfindung betrifft ein Verfahren zur Trennung von Bildröhrenglas von Bildröhren und dessen Reinigung gemäß Anspruch 1 und eine Vorrichtung zur Durchführung des Verfahrens gemäß Anspruch 9.The invention relates to a method for separating picture tube glass from picture tubes and its cleaning according to claim 1 and a device for performing the Method according to claim 9.
Eine Bildröhre besteht zu ca. 85% aus Glas, wobei das Schirmglas (60%) 13% Barium und das Konusglas (25%) 15% Bleioxid und 4% Barium enthalten.A picture tube consists of approx. 85% glass, the screen glass (60%) 13% barium and the cone glass (25%) contains 15% lead oxide and 4% barium.
Bleioxid und Barium werden zum Strahlenschutz eingesetzt.Lead oxide and barium are used for radiation protection.
Der Schirm ist innen mit Phosphorleuchtstoff und der Konus mit einem leitenden Lack besprüht. Defekte Bildröhren, der sogenannte Ausschuß, wurden bis jetzt meistens auf ei ne Deponie gebracht. Dadurch gingen erhebliche Mengen an teuerem Glas (ca. 17 kg pro Bildröhre) verloren.The inside of the shade is made of phosphor and the cone is made of a conductive varnish sprayed. Broken picture tubes, the so-called committee, have so far mostly been on egg brought a landfill. This resulted in considerable amounts of expensive glass (approx. 17 kg per Picture tube) lost.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren nach dem Oberbegriff des Pa tentanspruches 1 so zu bilden, daß der Glasanteil einer Bildröhre von den anderen Be standteilen befreit und gereinigt wird, um eine Wiederverwertung des Glases zu ermögli chen.The invention has for its object to form a method according to the preamble of Pa tentanspruches 1 so that the glass portion of a picture tube from the other loading components is freed and cleaned in order to enable recycling of the glass chen.
Diese Aufgabe wird bei dem gattungsgemäßen Verfahren bzw. mit der gattungsgemäßen Vorrichtung durch die kennzeichnenden Merkmale der Ansprüche 1 bis 8 bzw. 9 gelöst.This object is achieved with the generic method or with the generic Device solved by the characterizing features of claims 1 to 8 and 9 respectively.
Die mit diesem Verfahren und der dazugehörigen Vorrichtung erzielten Vorteile bestehen insbesondere darin, daß der Konus und der Schirm sauber voneinander getrennt und von ihren jeweiligen Beschichtungen befreit werden. The advantages achieved with this method and the associated device exist especially in that the cone and the screen are cleanly separated from each other and from their respective coatings are exempted.
Dadurch können die gesäuberten Glasteile wiederverwendet werden, wodurch die Depo nien entlastet und die Bildröhren günstiger hergestellt werden können.This allows the cleaned glass parts to be reused, which makes the depo relieved and the picture tubes can be manufactured cheaper.
In Fig. 1 wird in schematischer Darstellung eine Bildröhre in einer Explosions-Zeichnung dargestellt.In Fig. 1, a picture tube is shown in an exploded view in a schematic representation.
Die Bildröhre besteht von vorne nach hinten gesehen aus einem Schirm 2 mit einer innen aufgebrachten Leuchtschicht 2.1, einem Implosionsschutzrahmen 5, einer Maske 6, einem Konus 1 mit einer innen aufgebrachten Beschichtung 1.1, einem Ablenker 4 und einem Strahlerzeuger 3. Die Maske 6 ist hinter dem Schirm 2 im Maskenrahmen 6.1 eingespannt. Der Schirm 2 ist mit dem Konus 1 fest verbunden.Viewed from front to back, the picture tube consists of a screen 2 with an internally applied luminous layer 2.1 , an implosion protection frame 5 , a mask 6 , a cone 1 with an internally applied coating 1.1 , a deflector 4 and a beam generator 3 . The mask 6 is clamped behind the screen 2 in the mask frame 6.1 . The screen 2 is firmly connected to the cone 1 .
Der Strahlerzeuger 3 ist im Konus 1 an dessen Ende integriert und der Ablenker 4 ist auf dem Konus 1 aufgeklebt. Das Verfahren sieht vor, den Konus 1 vom Schirm 2 mittels ei ner Trennscheibe 8 (z.B. eine Diamantscheibe) abzutrennen und die Beschichtungen 1.1, 2.1 vom Glas abzustrahlen. Das Abstrahlen kann z.B. mit Sand oder Wasser unter Hoch druck erfolgen.The jet generator 3 is integrated in the cone 1 at its end and the deflector 4 is glued to the cone 1 . The method provides for the cone 1 to be separated from the screen 2 by means of a cutting disk 8 (for example a diamond disk) and to radiate the coatings 1.1 , 2.1 from the glass. The blasting can be done with sand or water under high pressure.
Das Abstrahlgut bzw. das ablaufende Abwasser muß entweder fachgerecht entsorgt bzw. zur Wiederverwertung bei einer Kreislaufführung aufbereitet werden.The blasting material or the running waste water must either be disposed of properly or be recycled for recycling.
Die Metallteile (Strahlerzeuger 3, Ablenker 4, Implosionsschutzrahmen 5 und Maske 6) werden vom Glas abgetrennt und entfernt. Die Abtrennung kann z.B. durch das Absaugen oder ein einfaches Lösen und die Entfernung der Metallteile magnetisch erfolgen.The metal parts (beam generator 3 , deflector 4 , implosion protection frame 5 and mask 6 ) are separated from the glass and removed. The separation can be done magnetically, for example by suction or simply loosening and removing the metal parts.
Die erfindungsgemäße Vorrichtung weist demzufolge mindestens eine Trennscheibe 8, ei nen Metallabscheider 9 und eine Abstrahlvorrichtung 10 auf.The device according to the invention accordingly has at least one cutting disc 8 , egg NEN metal separator 9 and a radiation device 10 .
