Description
Vynález rieši ochranu spalovacej trubice zamedzením styku úletov taveniny z taviaoeho kelímka s křemennou spalovacou trubioou.SUMMARY OF THE INVENTION The present invention provides for the protection of a combustion tube by avoiding contact of molten material from the crucible with a quartz combustion tube.
Doteraz známe spalovacie trubice majú v ose uložený taviaci kelímek, v ktorom sa taví vzorok vysokofrekvenčným ohrevom. Unika júce úlety žeravej časti taveniny narušujú štruktúru a celistvosť plynotesnej spalovacej trubice, ktorá odděluje chemický proces prebiehajúci pri tavení od vonkajšej atmosféry. Narušená plynotesnosť spalovacej trubice znemožňuje jej ďalšie použitie pre analýzu.The prior art combustion tubes have a melting crucible in the axis in which the sample is melted by high-frequency heating. The escaping fumes of the glowing portion of the melt disrupt the structure and integrity of the gas-tight combustion tube which separates the chemical process occurring during melting from the external atmosphere. The disturbed gas-tightness of the combustion tube prevents its further use for analysis.
Vyššie uvedené nedostatky sú odstránené spalovacou trutoicou podl’a vynálezu, ktorého podstata spočívá v tom, že v hornej časti spalovacej trubice je zúženie, na ktorom je podpornými výstupkami zavesená ochranná trubička kuželovitého tvaru. Trubička je stabilizovaná v ose spalovacej trubice výstupkami, ktoré sú nad horným okrajom taviaceho kelímka.The above-mentioned drawbacks are overcome by the combustion trutoic according to the invention, which is characterized in that in the upper part of the combustion tube there is a constriction on which a conical-shaped protective tube is suspended by the supporting projections. The tube is stabilized in the axis of the combustion tube by protrusions that are above the upper edge of the crucible.
Pokrok dosiahnutý vynálezom spočívá v tom, že zariadenie zachytává unikajúce úlety tekutých častí taveniny a -tým zabráni ich styku so spalovacou trubicou, čím sa docieli predlženie životnosti spalovacej trubice.The progress achieved by the invention is that the device intercepts leaks of liquid parts of the melt and thus prevents their contact with the combustion tube, thereby extending the service life of the combustion tube.
Na priloženom výkrese je znázorněná spa1’ovacia trubica podlá vynálezu.In the attached drawing, a combustion tube according to the invention is shown.
V hornej časti kremennej spalovacej trubice 1, ktorá je s přístroj om plynotesne spojená těsněním 2, je upravené zúženie 3 s vnútomým priemerom o 1—2 mm vačším ako je vonkajší priemer taviaceho kelímka 4, ktorý stojí na podstavci 8 v střede vysokofrekvenčného póla. Na zúžení 3 je zavesená ochranná trubička 6 kuželovitého tvaru, podpornými výstupkami 7, ktoré sú natavené na homom okraji ochramiej trubičky 6. Od 'taviaceho ke216294In the upper part of the quartz combustion tube 1, which is gas-tightly connected to the apparatus by a seal 2, a constriction 3 is provided with an inner diameter of 1-2 mm larger than the outer diameter of the crucible 4 which stands on the base 8 in the middle of the high-frequency pole. A conical protective tube 6 is hinged to the constriction 3, with support projections 7, which are fused at the upper edge of the protective tube 6.

límka 4 je odhranná trubička 6 vzdialená o 3—4 mim. Nad úrovňou horného okraja taviaeeho kelímka. 4 je po obvode spalovacej* trubice 1 vytvořených šesť výstupkov 5 směrem dovnútra, ktoré slúžia na stabilizáciu ochrannej trubičky 6 v ose spalovacej trubice 1.The collar 4 is a bend tube 6 spaced 3-4 m. Above the top of the taviaee crucible. 4, six protrusions 5 are formed inwardly around the periphery of the combustion tube 1, which serve to stabilize the protective tube 6 along the axis of the combustion tube 1.
