Description

148238148238

Opfindelsen angår et apprat til opbygning og udbedring af den ildfaste udforing i industrielle ovne og varmt arbejdende beholdere ved selektiv påslyng-ning af kornet ildfast materiale på de steder af udforingen, som skal opbygges eller udbedres, med en drejeligt lejret centrifugalskive, som er anbragt nedssan-keligt i vandret plan i ovnens eller beholderens indre, og til hvilken det ildfaste materiale kan tilføres gennem en oven over centrifugalskiven udmundende ledning, gennem hvilken den lodrette drivaksel for centrifugalskiven strækker sig, og som er tilsluttet til et blandekammer, hvis øvre ende er forbundet med en materialebeholder, hvorhos tilførslen af ildfast materiale fra materialebeholderen til blandekammeret er indstillelig ved hjælp af et styreelement, som ændrer tilførselstværsnittet.BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to an apparatus for constructing and repairing the refractory casing in industrial furnaces and hot working containers by selectively casting grain-refractory material at the locations of the casing to be constructed or repaired with a rotatably mounted centrifugal disc mounted horizontal in the oven or container, to which the refractory material may be supplied through a line extending above the centrifugal disk through which the vertical drive shaft of the centrifugal disk extends and connected to a mixing chamber whose upper end is connected with a material container wherein the supply of refractory material from the material container to the mixing chamber is adjustable by a control element which changes the supply cross section.

Ved sådanne kendte indretninger består styreelementet, som mellem materialebeholderen og blandekammeret aaidrer tilførselstværsnittet, af på tværs af føderetningen forskydelige klapper. Disse klapper har den ulempe, at de under driften er følsomme over for forstyrrelser og kun tillader en meget grov regulering af materialestrømmen. Der er også allerede foreslået magnetventiler til styring af materialestrømmen. Disse magnetventiler er imidlertid konstruktivt komplicerede og finder kun anvendelse i indretninger, hvor styreelementet ikke udsættets for alt for store temperaturforskelle.In such known devices, the control element, which separates the supply cross-section between the material container and the mixing chamber, consists of slidable slides across the feed direction. These flaps have the disadvantage that during operation they are sensitive to disturbances and allow only a very rough control of the material flow. Solenoid valves have also been proposed for controlling the flow of material. However, these solenoid valves are constructively complicated and are only applicable in devices where the control element is not exposed to excessive temperature differences.

Opfindelsen har til opgave at tilvejebringe en apparat af den indledningsvis anførte art, der også under ublide betingelser muliggør en finregulering af materialestrømmen til blandekammeret og arbejder upåklageligt også ved store temperaturforskelle·The invention has for its object to provide an apparatus of the kind mentioned in the preamble, which also enables, under unconditional conditions, a fine control of the material flow to the mixing chamber and works impeccably even at large temperature differences.

Denne opgave løses ifølge opfindelsen ved, at den kegleformede materialebeholder oven over det cylindriske blandekammer er ringformet afbrudt, at der •ved dette afbrydelsessted er hængende anbragt i alt væsentligt trapezformede plader i en cirkel, hvilke plader ved deres egenvægt ligger an med deres smalsider mod den øvre rand af den derunder værende naterialebeholderdel og derved frigiver ringtværsnittet mellem drivakslens lejehus og materialebeholderen, og at pladerne med på bagsiden anbragte fremspring ligger an mod styrekurveafsnit af en i huset drejeligt lejret vandret ring, ved hvis drejning i den ene retning,, fx. ved hjælp af en pneumatisk drivmekanisme, pladerne kan svinges ind mod lejehuset til deres lukkestilling.This task is solved according to the invention in that the cone-shaped material container above the cylindrical mixing chamber is annularly interrupted, that at this point of interruption, substantially trapezoidal plates are arranged in a circle, which plates at their own weight abut their narrow sides against the upper edge of the material container portion thereof, thereby releasing the annular cross-section between the drive shaft bearing housing and the material container, and the plates with projections located at the rear abut against the guide curve section of a rotatably horizontal ring in the housing, if rotated in one direction, e.g. By means of a pneumatic drive mechanism, the plates can be pivoted towards the bearing housing to their closing position.

Opfindelsen er nærmere forklaret i det følgende under henvisning til tegningen, på hvilken fig. 1 viser et lodret snit af et apparat ifølge opfindelsen, fig. 2 et vandret snit af det i fig. 1 viste apparat.The invention is further explained in the following with reference to the drawing, in which: FIG. 1 shows a vertical section of an apparatus according to the invention; FIG. 2 is a horizontal section of the embodiment of FIG. 1.

Som vist i fig. 1, består apparatet til opbygning og udbedring af den ildfaste udforing i industrielle ovne og varmt arbejdende beholdere af en kegleformet materialebeholder 1, et dertil sluttet cylindrisk blandekammer 2 og en derfra nedad forløbende tilførselsledning 3, under hvilken en centrifugalskive er fastgjort på en lodret drivaksel 5, som er drejeligt lejret i et lejehus 6, og som med en transportdel 7, dvs. med en snegl eller lignende, strækker sig gennem blandekammeret 2 og den derunder liggende tilførselsledning 3.As shown in FIG. 1, the apparatus for building and repairing the refractory liner in industrial furnaces and hot working containers consists of a cone-shaped material container 1, a connected cylindrical mixing chamber 2 and a downwardly extending supply line 3, under which a centrifugal disc is mounted on a vertical drive shaft 5 which is pivotally mounted in a bearing housing 6, and as with a transport part 7, i. with a auger or the like, extends through the mixing chamber 2 and the underlying supply line 3.

Den kegleformede beholder 1 er afbrudt i et bestemt område 8 og på dette sted forsynet med i en cirkel ved siden af hinanden hængende anbragt tra-pezformede plader 9 - 20, og som i deres til højre i fig. 1 og 2 viste lukkestilling med deres nedre rand 21 ligger an mod en fra lejehuset udragende ring 22.The cone-shaped container 1 is interrupted in a particular area 8 and at this location is provided with a trapezoidal plates 9-20, which are arranged in a circle adjacent to each other, and as in their right in FIG. 1 and 2 with their lower rim 21 abutting against a ring 22 projecting from the bearing housing.

I den til venstre på fig. 1 og 2 viste åbne stilling har pladerne indbyrdes afstand og ligger under indvirkning fra deres egenvægt med deres nedre rand 21 an mod de øvre rande 23 af beholderen 1's nedre del.In the left of FIG. 1 and 2, the plates are spaced apart and are under the influence of their own weight with their lower rim 21 against the upper edges 23 of the lower portion of the container 1.

Pladerne 9-20 ligger med på deres bagside anbragte fremspring 24 - 29 an mod styrekurveafsnit 30 - 33 på en ring 35, som fx. kan drejes ved hjælp af en pneumatisk drivmekanisme 34, så at pladerne 9-20 alt efter drejningsstillingen af denne ring kan bringes i åben stilling (til venstre på fig. 1) eller i lukket stilling (til højre på fig. 1).The plates 9-20 bear on their backsides projections 24-29 against the control curve sections 30-33 on a ring 35, e.g. can be turned by means of a pneumatic drive mechanism 34 so that the plates 9-20 can be moved into the open position (to the left of Fig. 1) or to the closed position (to the right of Fig. 1), depending on the rotation position of this ring.

På fig. 2 er pladerne 15-19 vist så dybt gennemskåret, at man bedre kan se bagsidefremspringene 26-29.In FIG. 2, the plates 15-19 are shown so deeply cut that one can better see the rear projections 26-29.
