Description

Siebrundbeschicker zur Aufbereitung von Ton od. dgl. Es ist bekannt, während der Aufbereitung von Ton dem Gut in verschiedenen Verfahrensstufen Dampf zuzuführen.Circular sieve feeder for processing clay or the like. It is known During the preparation of clay, the goods are steamed in various process stages to feed.

Es wurde auch bereits vorgeschlagen, einen als Zuteil- und Mischvorrichtung ausgebildeten Rundbeschicker, dessen Einschüttbottich in der unteren Hälfte der Wandung mit Durchbrechungen versehen ist, durch welche das Material mittels einer Durchstreichvorrichtung einem unter dem Bottich befindlichen Sammelteller zugeführt wird, durch eine Ringleitung zum Zwecke des Tona!afschlusses mit Dampf zu beschicken.It has also been proposed to use one as a dispensing and mixing device trained round feeder, whose pouring tub in the lower half of the Wall is provided with openings through which the material by means of a Strikethrough device fed to a collecting plate located under the vat is to be charged with steam through a ring line for the purpose of closing the tone.

Die Erfindung bezweckt, einen Siebrundbeschicker von allgemein üblicher Bauart, der aus einem zylindrischen.. Einschüttbottich mit in der unteren Hälfte der Wandung angebrachten Durchbrechungen mit einer Siebbespannung besteht, durch welche das Material mittels einer DurchstreichvoTrichtung 'einem unter dem Bottich befindlichen Sammelteller zugeführt wird, mittels einer an bestimmter Stelle angeordneten Dampfzuführung in Arbeitsweise und Leistung zu verbessern. Das geschieht gemäß der Erfindung durch Taschen mit Abdeckblechen zur Dampfeinleitung am Umfange des Bottichbodens unterhalb der mit einer Siebbespannung versehenen Durchbrechungen. Die Dampfeinlässe münden in die Taschen radial, wobei die Abdeckbleche der Taschen mit ihren Kanten in an sich bekannter Weise sich schuppenförmig übergreifen, so daB gegen die Dampfeinlässe in Umfangsrichtung des Bottichbodens versetzte düsenfö@rrnige Schlitze entstehen, die von dem in den Taschen rechtwinklig umgelenkten Dampfstrom ständig gereinigt werden. Durch dieAustrittsschlitze gelangt der Dampf in gleichmäßiger Verteilung in das Bottichinnere, in dem er nach oben steigt. Er nimmt dabei seinen Weg in der Hauptsache unmittelbar an .der Bottichwand und erfaßt dabei besonders g=ut die an den Sieböffnungen in Bildung begriffenen kleinen Tonfladen und -würstchen.The aim of the invention is to provide a circular screen feeder that is generally more common Design consisting of a cylindrical .. pouring tub with in the lower half the wall attached openings with a sieve covering, through which the material by means of a strikethrough device under the vat located collecting plate is supplied, by means of a arranged at a certain point To improve steam supply in operation and performance. This happens according to the Invention through pockets with cover plates for introducing steam on the perimeter of the bottom of the tub below the perforations provided with a screen covering. The steam inlets open into the pockets radially, the cover plates of the pockets with their edges overlap in a manner known per se, so that against the steam inlets in Circumferential direction of the bottom of the vat, staggered nozzle-shaped slots arise, which are constantly caused by the steam flow deflected at right angles in the pockets getting cleaned. The steam flows more evenly through the outlet slits Distribution into the inside of the vat, where it rises to the top. He takes his Path mainly directly to the wall of the vat and particularly captured g = ut the small clay patties and sausages that are being formed at the sieve openings.

Die erfindungsgemäße Dampfzuführung . wirkt sich besonders vorteilhaft nach Betriebspausen aus, in denen der Bottich nicht vollkommen - entleert wurde und insbesondere in den Öffnungen des Siebkorbes Gutreste h:ängengeblieben sind, w=elche während der Pause vertrockneten. Ein kurzzeitliches Dampfeinlassen vor Wiederaufnahme des Betriebes genügt, um das eingetrocknete Material wieder plastisch und schlüpfrig zu machen.The steam supply according to the invention. is particularly beneficial after breaks in operation in which the vat has not been completely emptied and in particular in the openings of the sieve basket residues h: have remained, w = which dried up during the break. Briefly letting in steam before resuming of operation is sufficient to make the dried-up material plastic and slippery again close.

An sich ist es bekannt, im Boden eines runden Beschickers Dampfkanäle anzuordnen, die naturgemäß nach oben abgedeckt sein müssen. Der bekannte Beschicke= enthält jedoch keine Siebbespannung, so daß die durch die Erfindung gelösten Probleme nicht erscheinen.It is known per se to have steam channels in the bottom of a round feeder to be arranged, which of course must be covered at the top. The well-known feeder = however, does not contain a screen covering, so that the problems solved by the invention non-appearance.

Eine beispielsweise Ausführungsform des Erfindungsgegenstandes ist in der Zeichnung dargestellt. Abb. i stellt einen senkrechten Schnitt durch den Einschüttbottich auf der Linie A-B der Abb. 2 dar; Abb. 2 ist eine Draufsicht, während Abb. 3 einen Schnitt durch den Stoß zweier aneinanderliegender Bodenbleche in etwas größerem Maßstabe auf der Linie C-D wiedergibt.An example embodiment of the subject matter of the invention is shown in the drawing. Fig. I represents a vertical section through the Pouring tub on line A-B of Fig. 2; Fig. 2 is a plan view while Fig. 3 shows a section through the joint between two adjacent floor panels in something on a larger scale on the line C-D.

Der Einschüttbottich i ist in der üblichen Weise in seiner unteren Hälfte mit einer Siebbespannung 2 versehen, durch deren Öffnungen das Material durch rotierende Abstreicher nach außen getrieben wird. Der Bottich i wird von einer Dampfleitung 3 umgeben, von welcher Abzweigzungen mit Dampfeinlässen 4 und 5 in das Bottichinnere führen. Die Dampfeinlässe sind Übereinander in zwei Zonen angeordnet. Vier an sich bekannte obere Einlässe 4 sind etwa in der Mitte der Bottichhöhe vorgesehen. Sie münden in radial in das Bottichinnere ragende Lochdüsen 6 aus. Weitere zehn über den ganzen Bottichumfang verteilte untere Dampfeinlässe 5 münden in den Bottichboden 7 aus. Letzterer ist zu dem Zweck mit Taschen 8 versehen, die nach oben zu offen sind. Ihre Abdeckung erfolgt durch abnehmbare AbdeckbIeche 9, welche sich mit ihren radialen Stoßkanten io schuppenförmig übergreifen, so d'atB düsenförmige Schlitze 14 entstehen. Ventile z i und i2 dienen zum Regeln bzw. Absperren des Dampfzutritts.. An die Taschen 8 sind Entwässerungsleitungen 13 angeschlossen.The pouring tub i is in its lower part in the usual way Half provided with a screen covering 2, through the openings of the material through rotating scraper is driven outwards. The vat i is served by a steam pipe 3 surrounded by which branch tongues with steam inlets 4 and 5 in the tub interior to lead. The steam inlets are arranged one above the other in two zones. Four in itself known upper inlets 4 are provided approximately in the middle of the height of the tub. she open out into perforated nozzles 6 projecting radially into the interior of the tub. Another ten over Lower steam inlets 5 distributed over the entire circumference of the tub open into the bottom of the tub 7 off. For this purpose, the latter is provided with pockets 8 which open at the top are. Your cover is done by removable cover plates 9, which are with their radial abutting edges overlap in a scale-like manner, so d'atB nozzle-shaped slots 14 arise. Valves z i and i2 are used to regulate or shut off the steam access. Drainage lines 13 are connected to the pockets 8.

Die über den Umfang des ganzen Bottichbodens 7 verteilten Taschen 8 bewirken eine Bedampfung der Bodenfläche, vorzugsweise in der Nähe der Siebbespannung, aber auch zum Bottichinneren hin. Diese Dampfwirkung wird noch erhöht durch die bei solchen Siebrundbeschickern erfolgende Rotation des Füllmaterials, im Bottich, weil dadurch immer wieder neue Schichten über die Austrittsschlitze 14 der Abdeckbleche 9 geführt werden. Die Schlitze zwischen den Blechen 9 werden durch den durchströmenden Dampf ständig rein- und sauhergehalten, so daß keine Verstopfungen entstehen. Zu dem Zweck wird der Dampf in die Taschen 8 seitlich eingeführt und innerhalb derselben in die Richtung der Schlitze 14 umgelenkt, welch letztere mithin düsenförmig wirken.The pockets distributed over the entire circumference of the bottom of the vat 7 8 cause steaming of the floor surface, preferably in the vicinity of the screen covering, but also towards the inside of the tub. This steam effect is increased by the Rotation of the filling material in the vat with such circular sieve feeders, because as a result, new layers over and over again via the outlet slots 14 of the cover plates 9. The slots between the sheets 9 are through the flowing through Steam is kept clean and clean at all times, so that no blockages arise. to for this purpose, the steam is introduced into the pockets 8 laterally and within the same deflected in the direction of the slots 14, the latter thus acting like a nozzle.
