Description
Foreliggende oppfinnelse, vedrører en. fremgangsmåte for oppvarming av hulsylindriske valser, for bølgepappmaskiner, samt en anordning for gjennomføring av denne, fremgangsmåte. The present invention relates to a method for heating hollow cylindrical rollers, for corrugated cardboard machines, as well as a device for carrying out this method.
Ifølge den vanlige, fremgangsmåte, for oppvarming av valser for bølgepappmaskiner, i dette tilfelle riflingsvalsen, trykkvalsen og tørkegruppen, skjer oppvarmingen utelukkende med damp. For denne oppvarming trenger man dampkjel, vannbehand-lingsanlegg, samt tanker for matevann og kondensvann. For rens-ingen trenger man i dag i tillegg et klaringsanlegg for utskil-ling av kjemikalier som blir tilsatt vannet.. For transport av dampen inn i bølgepappmaskinen kreves høyverdige pumper så vel som et omfattende rørledningsnett. For tilbakeføringen av kon-densvannet har det vært nødvendig med kondenspotter og dessuten kondensvannpumper. Da et dampanlegg er underlagt en regelmessig ettersynsplikt, har det vært nødvendig med omhyggelig vedlike-hold fra en kvalifisert maskinist. Anleggsomkostningene til et slikt dampanlegg har vært meget høye, slik at ikke bare dr.ifts-men også anskaffelsesomkostningene har skapt dårlig rentabili-tet. According to the usual method for heating rollers for corrugated board machines, in this case the rifling roller, the pressure roller and the drying group, the heating takes place exclusively with steam. For this heating you need a steam boiler, water treatment plant, as well as tanks for feed water and condensed water. Today, for cleaning, you also need a clarification plant for the separation of chemicals that are added to the water. To transport the steam into the corrugated cardboard machine, high-quality pumps as well as an extensive pipeline network are required. For the return of the condensate water, condensate pans and also condensate pumps have been necessary. As a steam plant is subject to a regular inspection obligation, careful maintenance by a qualified machinist has been necessary. The construction costs of such a steam plant have been very high, so that not only the operating but also the acquisition costs have created poor profitability.
Den foreliggende oppfinnelse har til oppgave å frembringe en fremgangsmåte, og en anordning for gjennomføring av denne fremgangsmåten, som gjør det mulig å. foreta oppvarmingen av valser for bølgepappmaskiner på en enkel og billig måte. The present invention has the task of producing a method, and a device for carrying out this method, which makes it possible to carry out the heating of rollers for corrugated cardboard machines in a simple and inexpensive way.
Dette kan ifølge oppfinnelsen oppnås ved at det i valsenes hulrom blir. forbrent en gass ved hjelp av en dysebrenner og valsene oppvarmet ved hjelp av varmestråling fra de frembragte brenngasser. According to the invention, this can be achieved by making the cavity of the rollers. burned a gas by means of a nozzle burner and the rollers heated by means of heat radiation from the produced combustion gases.
Oppfinnelsen omfatter dessuten en anordning for gjennomføring av denne, fremgangsmåte, som er kjennetegnet ved at det utenfor hver av valsene er anordnet en dysebrenner for gass, hvis dyse er rettet mot et brennrør som er anordnet i valsens indre idet det over dette befinner seg et strålingsrør som er anbragt for å danne en lufttilførsel i avstand fra brennrøret, og at det dessuten finnes midler for å kjøle valselagrene. The invention also includes a device for carrying out this method, which is characterized by the fact that a nozzle burner for gas is arranged outside each of the rollers, the nozzle of which is directed towards a combustion tube which is arranged inside the roller, with a radiation tube located above this which is arranged to form an air supply at a distance from the combustion tube, and that there are also means for cooling the roller bearings.
I tegningen er det vist skjematisk et eksempel på en u.tf ørelsesform av oppfinnelsen med et aksialsnitt gjennom en valse. The drawing shows schematically an example of an additional embodiment of the invention with an axial section through a roller.
Henvisnings tall 1 betegner en rif lingsvalse, for en bølgepappmaskin, som er utformet hulsylindrisk av stål pg som med sine to ender er opplagret i valselager 2. Henvisningstall 3 betegner en beholder for flytende gass, som over en rør-ledning 4 med en innebygget trykk-reduksjonsventil 5 er. forbundet med en dysebrenner 6. Henvisningstall 7 betegner en rør-ledning for blandeluft som fører til brenneren 6. Så vel i gassledningen som i luftledningen er det innebygget regulerings-og sperreventiler 8 hhv. 9. I den fremste del av valsens 1 indre er det anordnet et brennrør 11, som er rettet mot brennerens dyse. Nær opptil brennrøret 11 er det skjøvet teleskopartig Reference number 1 denotes a rifling roller, for a corrugated cardboard machine, which is designed as a hollow cylinder of steel pg which is stored with its two ends in a roller bearing 2. Reference number 3 denotes a container for liquefied gas, which over a pipeline 4 with a built-in pressure -reducing valve 5 is. connected to a nozzle burner 6. Reference number 7 denotes a pipeline for mixing air that leads to the burner 6. Both in the gas line and in the air line there are built-in regulating and shut-off valves 8 or 9. In the front part of the interior of the roller 1, there is arranged a combustion tube 11, which is directed towards the nozzle of the burner. Close to the combustion tube 11, it is pushed telescopically
over dette et strålingsrør 10 av krumnikkelstål. Strålingsrøret 10 er tilnærmet dobbelt så langt som brennrøret 11 og det strek-ker seg langs valsens 1 indre rom 17. Brennrøret 11 er. forsynt med hull 18. for inngang av tilleggsl.uft fra ringrommet 15' i strålingsrøret 10. I avstand fra strålingsrøret 10 er det på den side av valsen 1 som vender mot dysebrenneren 6 anbragt et varmeskjold 12 i valsens indre rom 17. Det rørformete varmeskjold 12 omgis av et ytre ringrom 15 som tjener til friskluft-tilførsel og samtidig til kjøling av valselagrene 2, mens et ringrom 16 som befinner seg mellom varmeskjoldet og strålings-røret, muliggjør uttrekking av brenngasser, slik pilen A antyd-er. Ved den høyre ende av valsen 1 i. figuren er det i det indre rom 17 anordnet et likeledes rørformet varmeskjold 13 koaksi-alt i valsen. Dette varmeskjoldet tjener samtidig til å holde en blende 14 som har en innstillbar parabe.lflate 14" og som kan føres aksielt i. forhold til varmeskjoldet. Blenden 14 har til. formål å snu brenngassene slik at de bestryker veggene i hulrommet og strålingsrøret 10 i retning mot varmeskjoldet 12 hhv. dysebrenneren. Varmeskjoldet 13 befinner seg i avstand above this a radiation tube 10 of chrome nickel steel. The radiation tube 10 is approximately twice as long as the combustion tube 11 and it extends along the inner space 17 of the roller 1. The combustion tube 11 is. provided with holes 18. for the entry of additional air from the annulus 15' into the radiation tube 10. At a distance from the radiation tube 10, on the side of the roller 1 facing the nozzle burner 6, a heat shield 12 is placed in the roller's inner space 17. The tubular heat shield 12 is surrounded by an outer annulus 15 which serves for fresh air supply and at the same time for cooling the roller bearings 2, while an annulus 16 which is located between the heat shield and the radiation tube, enables the extraction of combustion gases, as indicated by arrow A. At the right end of the roller 1 in the figure, a similarly tubular heat shield 13 is arranged in the inner space 17 coaxially in the roller. This heat shield also serves to hold a baffle 14 which has an adjustable parabolic surface 14" and which can be moved axially in relation to the heat shield. The baffle 14 has the purpose of turning the combustion gases so that they coat the walls of the cavity and the radiation tube 10 in direction towards the heat shield 12 or the nozzle burner The heat shield 13 is located at a distance
fra valsens indre vegg 1' og luften som strømmer inn gjennom det ringrom 15" som derved dannes kjøler det høyre valselager 2 i tegningen. from the roller's inner wall 1' and the air that flows in through the annulus 15" which is thereby formed cools the right roller bearing 2 in the drawing.
Gassen som sprøytes inn i brennrøret fra dysebrenneren 6 og som forbrennes når i dette en temperatur på ca. 1560 °C. Brennrøret 11 blir derved rødglødende. Strålingsrøret 10 blir likeldes oppvarmet og bevirker en ensartet, direkte over-føring av varmeenergien til den utenforliggende indre vegg 1' i valsen 1, slik det er antydet med pilene a. Varmen som opptas av den indre vegg 1' brer seg til valsens utvendige flate 1" og bevirker der, avhengig av den innstilte gasstilførsel, en temperatur mellom 100 og 2 50 °C. The gas that is injected into the combustion tube from the nozzle burner 6 and that is burned reaches a temperature of approx. 1560 °C. The combustion tube 11 thereby becomes red-hot. The radiation tube 10 is likewise heated and causes a uniform, direct transfer of the heat energy to the external inner wall 1' in the roller 1, as indicated by the arrows a. The heat absorbed by the inner wall 1' spreads to the outer surface of the roller 1" and causes, depending on the set gas supply, a temperature between 100 and 250 °C.
Brenngassene som strømmer gjennom brennrøret 11 blir snudd ved hjelp av blenden 14 og strømmer tilbake langs strålingsrørets 10 ytterside, idet de på veien mot varmeskjoldet 12 støter sammen med. friskl.uften som har. ført til kjøling av lageret. 2 og, forlater sammen med denne det indre rom 17 gjennom ringrommet 16. Ved hjelp av reguleringsventilene 8 og 9 kan brenne.rflammen og dermed også valse/temperaturen innstilles. Ved hjelp av den aksiale innstilling av blenden 14 i varmskjol-det 13 kan gjennomløpshastigheten til brenngassene og dermed også varmen i det indre rom 17 av valsen 1 påvirkes. The combustion gases flowing through the combustion tube 11 are reversed by means of the diaphragm 14 and flow back along the outside of the radiation tube 10, as they collide with the heat shield 12 on the way. the fresh air that has led to cooling of the warehouse. 2 and, together with this, leaves the inner space 17 through the annular space 16. With the help of the control valves 8 and 9, the burning flame and thus also the cylinder/temperature can be set. By means of the axial adjustment of the aperture 14 in the heat shield 13, the flow rate of the combustion gases and thus also the heat in the inner space 17 of the roller 1 can be influenced.
