Abstract

Dust suppression system for coal face shearers as in 2202296 consists of a compressed air powered duster so as to keep this in a permanently pressurised state. The air jet drive forces the spray water out without the use of space consuming pumps.

Description

Beschreibung und Erläuterung zur Patentanmeldung "Druckluftbetriebener Walzenschräntmaschineneritstauber". Zusatzpatentanmeldung zur Patentanmeldung P 22 02 296.4Description and explanation of the patent application "Pneumatically operated roller cutting machine eritstauber". Additional patent application for patent application P 22 02 296.4

In der Hauptanmeldung Aktenzeichen P 22 02 296.4 "Verfahren zur Staubbekämpfung bei Walzenschrämmaschinen in der Kohlegewinnung" wird ein Verfahren beschrieben, das dadurch gekennzeichnet ist, daß der Schneidraum der Walzenschrämmaschine durch eine Luftschranke, die aus Blasluftstrahlen besteht, pneumatisch abgeriegelt wird und aus diesem Schneidraum mittels Saugventilator und Entstauber eine erforderliehe Luftmenge aus dem durch die Luftschranke abgeschirmten Raum- abgesaugt wird, sodaß der Schneidraum entstaubt und die Sicht für den Walzenschrämmaschinenfahrer gewährleistet ist.In the main application file number P 22 02 296.4 "Procedure for combating dust on roller cutting machines in coal extraction " a method is described which is characterized in that the cutting space of the roller shearing machine through an air barrier consisting of jets of blown air, is pneumatically sealed off and a required amount of air from this cutting space by means of a suction fan and dust extractor sucked out of the room shielded by the air barrier so that dust is removed from the cutting area and visibility for the roller cutting machine operator is guaranteed.

Der nachstehende erfindungsgemäße Gedanke soll diese Einrichtung wesentlich verbes sern·The following idea according to the invention is intended for this device significantly improve

Bisher waren die Entstaubungseinrichtungen für Walzenschrämmaschinen durch Ventilatoren angetrieben.So far, the dedusting devices were for roller shearers driven by fans.

Der Antrieb mittels Ventilator ist sehr platzaufwendig und bedingt daher zahlreiche Umänderungen, insbesondere bei vorhandenen Walzenschrämmaschinen.The drive by means of a fan is very space-consuming and therefore requires numerous changes, especially with existing ones Roller cutting machines.

Um den Nachteil der Platzauf wendigkeit zu vermeiden wird erfindungsgemäß vorgeschlagen, eine Entstaubungseinheit zu benutzen, die durch Druckluft angetrieben ist undzwar erfindungsgemäß druckseitig, sodaß auch die saugseitigen Pumpen, die bei allen mit Ventilatoren angetriebenen Entstaubern notwendig sind, fortfallen können.In order to avoid the disadvantage of the amount of space required proposed according to the invention to use a dedusting unit, which is driven by compressed air undzwar according to the invention on the pressure side, so that also the suction side Pumps, which are necessary for all fan-driven dust extractors, can be omitted.

In der beiliegenden Zeichnung ist die er findungs gemäße Ausführung dargestellt. .In the accompanying drawing, he is the execution according to the invention shown. .

Selbstverständlich ist äie Erfindung nicht, auf die vorstehend im einzelnen dargestellten und beschriebenen Ausbildungsformen beschränkt, sondern es sind zahlreiche Abänderungen möglich, ohne jedoch von dem Grundgedanken abzuweichen, den staubhaltigen Raum einer Walzenschrämmaschine, der vorzugsweise durchLuftschranken abgeschirmt ist, mit Druckentstauberaggregateri abzusaugen, wobei diese Entstauberaggregate durch Luftstrahlantriebe die Absaug- und Abscheideleistung bewirken, wobei weiterhin erfindungsgemäß der Luftstrahlantrieb vor dem Entstauber gesetzt ist, sodaß das gesamte Entstaubungs-System unterüberdruck steht und die dort eingedüsteri Waschwässermerigen durch überdruck aus dem Entstauber-System ohne Einschälten einer Pumpe austreten.Of course, the invention is not limited to the above training forms shown and described in detail limited, but numerous changes are possible without, however, deviating from the basic idea, the dusty The room of a roller shearer, which is preferably screened off by air barriers, can be extracted with a pressure deduster, these dedusting units effect the extraction and separation performance by means of air jet drives, and continue to do so according to the invention, the air jet drive is set in front of the dust extractor is, so that the entire dedusting system is under overpressure stands and the washing water is dampened there by overpressure from the dust extraction system without switching on a pump step out.
