Abstract

Die Erfindung betrifft ein Verfahren und dessen technische Umsetzung zur Kühlung von Einsteigetüren/ Mannlöchern/ Schautüren/ Schauöffnungen/ Explosionstüren/ Explosionsklappen/ Reinigungstüren/ Feuerungsarmaturen in quadratischer, rechteckiger, runder, ovaler Bauform oder sonstiger Varianten, verschiedenster Bauart, verschiedenster Materialien und DIN-Normen.The invention relates to a method and its technical implementation for cooling entry doors / manholes / show doors / show openings / explosion doors / explosion flaps / cleaning doors / Feuerungsarmaturen square, rectangular, round, oval design or other variants, various designs, various materials and DIN standards.

Description

Stand der TechnikState of the art

Bei bekannten Einsteigetüren/Mannlöchern/Schautüren/Explosionstüren/Reinigungstüren aus Grauguss bestehend aus Türblatt 1 und Türrahmen 2 wird zusätzlich ein Schamottekasten 3 als Schutzelement zwischen Feuerraum und Außentürblatt 1 verwendet. Durch die Aufnahme der hohen Temperatur erhitzt sich die gesamte Tür und der Schamottekasten mit Schamotteauskleidung 3. Die Hitze staut sich und wird in keinster Weise abgeleitet. Bei höheren Temperaturen wird zusätzlich als Schutz eine Keramikplatte 4 und zusätzlicher Isolierstein 5 (mehrteilig) vorgesetzt. Im hochhitzebeständigen Bereich wird statt Grauguss Edelstahlguss eingesetzt. Die Konstruktion wird nachhaltig beschädigt, deformiert sich, Rissbildung im Guss, Ausbrechen der Schamotteauskleidung. Eine Verletzungsgefahr (Verbrennungen) im Außenbereich besteht permanent.In known entry doors / manholes / doors / explosion doors / cleaning doors made of gray cast iron consisting of door leaf 1 and door frame 2 a fireclay box 3 is additionally used as a protective element between the firebox and outer door leaf 1. By absorbing the high temperature heats the entire door and the fireclay box with fireclay lining 3. The heat accumulates and is not dissipated in any way. At higher temperatures, a ceramic plate 4 and additional insulating stone 5 (multi-part) is additionally used as protection. In the highly heat-resistant area, instead of cast iron, stainless steel casting is used. The construction is permanently damaged, deforms, cracking in the cast, breaking out of the fireclay lining. A risk of injury (burns) in the outdoor area is permanent.

Somit ist es Aufgabe der Erfindung die Wärme abzuleiten und die komplette Tür zu kühlen. die Erhaltung der Tür und die Verletzungsgefahr zu unterbinden.Thus, it is an object of the invention to dissipate the heat and to cool the entire door. to prevent the preservation of the door and the risk of injury.

Durch das nachstehende Verfahren entfällt der Schamottekasten 3 mit Schamotteauskleidung, die Keramikplatte 4 und die Isolier- bzw. Schutzsteine 5. Die hitzebeständige Gussausführung entfällt komplett.The following procedure eliminates the Schamottekasten 3 with fireclay lining, the ceramic plate 4 and the insulating or protective stones 5. The heat-resistant cast execution is completely eliminated.

Türblatt 1 und Türrahmen 2 behalten ihre ursprüngliche Form. Zusätzlich erhält das Türblatt einen Stutzen 10 zur Kühlmittelzufuhr, welcher durch ein Aggregat 14 gespeist wird.Door leaf 1 and door frame 2 retain their original shape. In addition, the door leaf receives a nozzle 10 for coolant supply, which is fed by an assembly 14.

Das Kühlmittel gelangt durch den Stutzen 10 in den Luftkasten 7 und entweicht über die umlaufenden Luftauslassschlitze 8.The coolant passes through the nozzle 10 in the air box 7 and escapes through the circumferential Luftauslassschlitze eighth

Es entsteht ein permanentes Luftpolster 12 umlaufend zwischen Ofen- bzw. Kesselwand 6 und Türrahmen 2 und Luftkasten 7.The result is a permanent air cushion 12 circumferentially between the furnace or boiler wall 6 and door frame 2 and air box. 7

Das Kühlmittel bzw. die Kühlluft entweicht dann in den Stauraum 11.The coolant or the cooling air then escapes into the storage space 11.

Das Kühlmedium kühlt jetzt die Abdeckelemente 9 zum Feuerraum hin.The cooling medium now cools the cover elements 9 towards the firebox.

Über Luftschlitze 13 in den Abdeckelementen 9 wird das Kühlmedium kontrolliert in den Feuerraum bzw. Brennraum geleitet und als zusätzliche Sekundärluft genutzt.Via air slots 13 in the cover 9, the cooling medium is controlled in the combustion chamber or combustion chamber and used as additional secondary air.

Türblatt 1 mit Luftkasten 7 werden nach außen geöffnet. Abdeckelemente 9 mit Scharnier- und Aufhängevorrichtung 15 wird nach innen geöffnet.
