Description
Aus endlosen Bändern bestehende Ketten-oder Wanderroste von Feuerungen für feste Brenn stoffe, aber auch von Saugzugsinter-, Sinterröstapparaten und ähnlichen Vorrichtungen zeigen oft die Erscheinung, daß auch bei einem angewendeten Rostbelag einzelne Teile des Röst- oder Sintergutes an den roststäben festbacken oder sich zwischen, sie verklemmen. Dies führt zu einer lästigen Verstopfung der Sinterbänder, Ketten-oder Wanderroste, den Roststäbe beim leeren Rücklauf des endlosen Rostes von Hand gereinigt werden müssen, was zeitraubende Handarbeit verursacht und zuweilen trotzdem nicht einwandfrei durchführbar ist, da die fest an den Roststäben haftenden Teile des Sintergutes mit Eisenstangen u. a. von Hand nicht völlig entfernbar sind. Chain or traveling grates of furnaces consisting of endless belts for solid fuels, but also for induced draft sintering and sintering roasters and the like Devices often show the appearance that even with an applied grate coating individual parts of the roasted or sintered food stick to the grate bars or get stuck between, they jam. This leads to an annoying clogging of the sinter belts, Chain or traveling grates, the grate bars when the endless grate returns empty need to be cleaned by hand, which causes time-consuming manual labor and at times is still not feasible because the grate sticks firmly to the grate bars Parts of the sintered material with iron bars, etc. cannot be completely removed by hand.
Ein Bearbeiten des leer zurücklaufenden Sinterbandteiles mit den bisher üblichen mechanischen Klopf- oder Reinigungsvorrichtungen führt nur zu einer teilweisen Besserung, da während der Zeit, in der der leer zurücklaufende Bandteil zur Verfügung sbeht, nicht alle festgesinterten Teile von den Roststäben abgeklopft werden können. Steigert man aber nun erfindungsgemäß die Zahl der Bearbeitungsstöße in der Zeiteinheit, etwa vermittels schnell laufender, mechanisch oder elektromagnetischer Rüttler durch Vibrationen mit hoher Frequenz oder vermittels ähnlicher Vorrichtungen, mit denen man den leeren Rostteil bearbeitet, so tritt eine wesentliche Verbesserung der Ablösung der an den Roststäben festgefritteten Teilchen ein, zumal wenn man Frequenzgebiete benutzt, die den Eigenschwingungen oder Resonanzen der Roststäbe entsprechen. Hier genügt dann eine relativ kurze Strecke des Rostes, die bearbeitet werden muß, um alle Teilchen abzulösen. A processing of the empty returning sintered belt part with the hitherto customary mechanical knocking or cleaning devices only leads to one partial improvement, since during the time in which the empty backward part of the belt available, not all of the firmly sintered parts are knocked off the grate bars can be. If, however, according to the invention, the number of machining impacts is increased in the unit of time, for example by means of fast moving, mechanical or electromagnetic Vibrators by vibrations with high frequency or by means of similar devices, with which one processes the empty grate part, there is a substantial improvement the detachment of the particles stuck to the grate bars, especially when you Frequency ranges used, the natural vibrations or resonances of the grate bars correspond. A relatively short section of the grate is then sufficient to process must be in order to detach all particles.
Die günstigste Frequenz richtet sich nach Material und Maßen der Roststäbe, nach den sich daraus und aus- der Befestigung der Stäbe ergebenden Resonanzbereichen, nach der Oberflächen beschaffenheit der Stäbe und kann jeweils durch praktische Versuche ermittelt werden. The most favorable frequency depends on the material and dimensions of the Grate bars, according to the resonance ranges resulting from this and from the fastening of the bars, according to the surface quality of the rods and can each by practical Trials are determined.
Die Vorrichtung nach der Erfindung kann außer an Ketten- oder Wanderrosten für Feuerungen besonders vorteilhaft an Sinter-oder Röstbändern in der Kies- und Blenderöstung, Abbrand-, Staub-und Erzsinterung, Zementindustrie, Bauxit- und Phosphataufbereitung sowie für das Sintern und Brennen von Kalk, Dolomit, Magnesit, Gips, Tonerde u. dgl. benutzt werden. The device according to the invention can be used except on chain or traveling grids for furnaces particularly advantageous on sintering or roasting belts in the gravel and Blind roasting, burn-off, dust and ore sintering, cement industry, bauxite and phosphate processing as well as for the sintering and burning of lime, dolomite, magnesite, gypsum, clay and the like. Like. Be used.
Beispiel Unter dem leer zurücklaufenden Teil eines Sinterbandes (a) der Abbildung, das Roststäbe von 190 mm Länge besitzt, die einen rechteckigen Querschnitt von 18X60 mm haben, ist ein elektromagnetisch angetriebener Rüttler (b) angebracht, der 3000 Stöße in der Minute von unten auf die Roststäbe des Sinterbandes ausübt, das zur Sinterung von Kakhydrat aus der Trockenvergasung von Calciumcarbid dient. Example Under the empty part of a sintering belt (a) the figure, which has grate bars 190 mm long and rectangular in cross-section of 18X60 mm, an electromagnetically driven vibrator (b) is attached, which exerts 3000 impacts per minute from below on the grate bars of the sintered belt, which is used for sintering kakhydrate from the dry gasification of calcium carbide.
Die Roststäbe gleiten mit einer Wanderungsgeschwindigkeit von 1000 mm in der Minute über den Rüttler und sind nach 200 mm Behandlungslänge, entsprechend 0,2 Minuten Behandlungsdauer, völlig frei von Teilen des Sintergutes. The grate bars slide at a speed of 1000 mm per minute over the vibrator and are accordingly after 200 mm treatment length 0.2 minutes treatment time, completely free of parts of the sintered material.
