Description

Reinigungsvorrichtung für Klassierroste Es sind Rollenroste bekannt, die zur Zerlegung großstückigen Siebguts dienen und bei denen auf dem Rollenrost bewegliche oder feststehende Stabroste angeordnet werden.Cleaning device for classifying grates Roller grates are known which are used to cut large pieces of material to be screened and for those on the roller grate movable or fixed bar gratings can be arranged.

Solche Roste lassen sich aber ohne Reinigungsvorrichtung nur zur Trennung stückigen, nicht schmierenden Siebguts verwenden. Will man nämlich damit aus beispielsweise schmierender Rohbraunkohle kleinste Körnungen bis etwa io mm Größe abtrennen, so setzen sich die engen Spalte zwischen den Rostrollen durch das schmierende Siebgut zu. Die vorgeschlagenen Reinigungsvorrichtungen führten nicht zum Ziel. Nach einem bekannten Vorschlage sollten sämtliche Walzen nacheinander mittels fahrbarer, unter dem Rost liegender Abstreicher gereinigt werden.Such grids can only be used for separation without a cleaning device Use lumpy, non-lubricating material to be sieved. If you want to get out of it, for example Separate the smallest grain sizes from lubricating raw lignite up to about 10 mm in size, see above the narrow gaps between the grate rollers settle through the lubricating screenings to. The proposed cleaning devices did not achieve the goal. After a known proposals should all rollers one after the other by means of mobile, under scrapers lying on the grate are cleaned.

Die Zeitspanne der Reinigung der einzelnen Walze ist zu groß, so daß sich die Spalte zusetzen und längere Zeit verstopft bleiben, bis eben der Abstreicher die betreffende Walze wieder gereinigt hat. Außerdem sind jene bekannten Abstreicher verwickelt in ihrem Aufbau und betriebsunsicher, da bei Erlahmung der angewendeten Federn die Einrichtung versagt.The period of time for cleaning the individual roller is too long, so that the crevices become clogged and remain clogged for a long time, until the scraper has cleaned the relevant roller again. Also, those are well known scrapers entangled in their structure and unsafe to operate, as the applied ones paralyze Springs the facility fails.

Durch die vorliegende Erfindung sollen diese Mängel beseitigt werden. Es wird eine Reinigungsvorrichtung verwendet, die sich zwischen zwei benachbarten Walzen des Rostes hin und her bewegt.The present invention aims to overcome these shortcomings. A cleaning device is used, which is located between two adjacent ones Rolling the grate back and forth.

Hierbei kann der Spalt zwischen Scheiben benachbarter Rollen bzw. Walzen bis zu einem kleinsten Maß sinken, wenn die Roststäbe in Eindrehungen zwischen Scheiben der Rostrollen liegen. Die Abstreicher sind mit Stäben des Stabrostes fest verbunden. Durch die Hinundherbewegung des Stabrostes werden die einzelnen Walzen von etwa anbackender Kohle gereinigt. Um dies zu erreichen, ist für je zwei Rollen ein mit dem Stabrost verbundener Abstreicher angebracht.Here, the gap between the discs of adjacent rollers or Rolls sink to a minimum when the grate bars are in between Slices of the grate rollers lie. The scrapers are fixed with bars of the bar grate tied together. The individual rollers are set by the back and forth movement of the bar grate cleaned of about caking coal. To achieve this, two roles are required for each a scraper connected to the bar grating is attached.

Die Stäbe c des Stabrostes liegen auf den Rollen a' des Rollenrostes oder in Eindrehungen b der Rollen. An diese Stäbe werden die Abstreichern befestigt. Die Wirkungsweise eines solchen Rollenstabrostes ist nun folgende: Rollen und Stabrost werden mittels der Kettenräder e durch Kette in Bewegung gesetzt, dabei machen die Rollen a des Rollenrostes eine drehende, die Stäbe c des Stabrostes durch den Antrieb/ .eine hin und her gehende Bewegung. Das Siebgut wird am Anfang des Rollenstabrostes bei g aufgegeben und wandert durch die Drehbewegung der Rollen a vorwärts. Die hin und her gehenden Stäbe c des Stabrostes bewegen nun die Abstreicher im gleichen Sinne, wobei von jeder der Rollen a das etwa anhaftende Siebgut abwechselnd durch einen von zwei aufeinanderfolgenden Querstäben oder Abstreichernd abgestrichen wird.The bars c of the bar grate lie on the rollers a 'of the roller grate or in grooves b of the rollers. The scrapers are attached to these bars. The mode of action of such a roller bar grating is now as follows: rollers and bar grating are set in motion by means of the chain wheels e Rolls a of the roller grate a rotating one, the bars c of the bar grate through the drive / .a back and forth motion. The material to be screened is at the beginning of the roller bar grate abandoned at g and moves forward due to the rotation of the rollers a. The go and moving bars c of the bar grate now move the scrapers in the same Meaning, whereby from each of the roles a the approximately adhering screenings through alternately one of two successive cross bars or scrapers is scraped off.
