Description

Die Erfindung betrifft eine Anlage zur Abförderung von bei der Papierherstellung anfallender Randstreifen nach dem Oberbegriff des einzigen Anspruchs, wie sie aus der DE-AS 12 53 570 vorbekannt ist.The invention relates to a system for the removal of edge strips occurring during paper production the preamble of the only claim as it derives from the DE-AS 12 53 570 is previously known.

Die vorbekannte Anlage neigt wegen der langen, zur Horizontalen nur wenig geneigten Rohrleitungen, die den Kreis bilden, in dem der Papierbrei herumgeführt wird, zum Verkleben bzw. zum Verstopfen.
The previously known system tends to stick or clog because of the long pipes, which are only slightly inclined to the horizontal, which form the circle in which the paper pulp is passed around.

Der Erfindung liegt damit die Aufgabe zugrunde, die Anlage der eingangs genannten derart weiterzubilden, daß ein Verkleben und Verstopfen vermieden wird.The invention is therefore based on the object To further develop the system of the above-mentioned that sticking and clogging is avoided.

Erfindungsgemäß wird diese Aufgabe durch die im kenn­ zeichnenden Teil des einzigen Anspruchs angegebenen Merkmale gelöst.According to the invention, this object is achieved by the drawing part of the single claim specified Features solved.

Die Erfindung wird im folgenden anhand einer Zeichnung erläutert.The invention is described below with reference to a drawing explained.

Dabei zeigt die einzige Figur eine schema­ tische Darstellung einer derartigen Anlage.The only figure shows a schematic table representation of such a system.

Ein Gebläse 1 erzeugt einen Unterdruck in einer Rohr­ leitung 2, die zu einem Trennbehälter 3 führt. An diesen Trennbehälter 3 ist weiter eine Ansaugleitung 4 angeschlossen, an deren anderem Ende eine Saugdüse 7 sitzt, die sich unmittelbar im Bereich des Randstrei­ fenabschneiders 8 befindet.A fan 1 generates a negative pressure in a pipe line 2 , which leads to a separation container 3 . At this separation container 3 , a suction line 4 is also connected, at the other end of which a suction nozzle 7 is seated, which is located in the region of the edge strip fenabschneiders 8 .

Von dem Trennbehälter 3 führt eine Rohrleitung 6 zu einem tiefer angeordneten Mischbehälter 5, wobei diese Rohrleitung 6 in den Mischbehälter 5 unterhalb dessen Flüssigkeitsniveau mündet. Rohrleitung 6 und Mischbe­ hälter 5 bilden so einen siphonartigen Wasserverschluß, durch den eine automatische Absperr-und Speiseeinrich­ tung gebildet wird und Unterdruckleckagen verhindert werden. Ein weiteres Rückleitungsrohr 10 führt von dem Mischbehälter 5 zu dem Trennbehälter 3.A pipe 6 leads from the separation tank 3 to a lower-lying mixing tank 5 , this pipe 6 opening into the mixing tank 5 below its liquid level. Pipeline 6 and Mischbe container 5 thus form a siphon-like water seal through which an automatic shut-off and Speiseeinrich device is formed and negative pressure leakage can be prevented. Another return pipe 10 leads from the mixing container 5 to the separation container 3 .

Von dem Gebläse 1 über die Rohrleitung 2 in den Trenn­ behälter 3 eingesaugte Papierstreifen treffen in diesem auf den durch die Rohrleitung 6, den Mischbehälter 5 und das Rückleitungsrohr 10 zirkulierend strömenden Papierbrei auf und werden von diesem aufgenommen.From the blower 1 via the pipe 2 in the separation container 3 sucked paper strips meet in this on the circulating through the pipe 6 , the mixing tank 5 and the return pipe 10 pulp and are taken up by this.

In den Oberteil des Trennbehälters 3 wird über einen Sprühkopf 9 die benötigte Flüssigkeit eingeführt. Der Flüssigkeitsstrahl wäscht dabei sowohl aus der durch die Rohrleitung 2 abgeführten Luft den Staub aus, dane­ ben wird aber auch an den Wänden des Trennbehälters 3 anhaftende Masse abgespült.The required liquid is introduced into the upper part of the separation container 3 via a spray head 9 . The liquid jet washes the dust from the air discharged through the pipeline 2 , but dane ben is also rinsed off adhering mass on the walls of the separation container 3 .

Die Anlage nach der Erfindung hat neben der Vermeidung eines Verklebens und Verstopfens eine Vielzahl von Vorteilen gegenüber vorbekannten Anlagen. Der Lei­ stungsbedarf ist verglichen mit vorbekannten Anlagen erheblich geringer. Da das Gebläse außerhalb der Pro­ duktionsräume angeordnet sein kann, ist die Lärment­ wicklung am Arbeitsplatz sehr gering. Die Abluft der Anlage ist gereinigt, die Anlage ist damit umwelt­ freundlich.The system according to the invention has in addition to avoidance of sticking and clogging a variety of Advantages over previously known systems. The lei The power requirement is compared to previously known systems significantly lower. Since the blower is outside the pro production rooms can be arranged is the noise development in the workplace is very low. The exhaust air of the System is cleaned, the system is therefore environmentally friendly friendly.
