Description
Schlauchfilter Es sind bereits Vorrichtungen zurn Reinigen von Filterschläuchen bekannt, bei denen die durch einen Schlauch oder eine Trommel gebildete Filterfläche mittels eines Ringkanals mit der Schlauchwandung zugekehrten Absaugeöffnungen gereinigt wird. Es ist nun nicht notwendig, die Luftabsaugung während der ganzen Betriebszeit wirken zu lassen.Bag filters There are already devices for cleaning filter bags known in which the filter surface formed by a hose or a drum cleaned by means of a ring channel with the hose wall facing suction openings will. It is now not necessary to use the air suction during the entire operating time let it work.
Man kann vielmehr, um an Reinigungsluft zu sparen, die Reinigung in größeren Zeitab' ständen vornehmen. Hierzu muß die Saugwirkung abgeschaltet werden.Rather, in order to save on cleaning air, cleaning can be carried out in make longer intervals. To do this, the suction must be switched off.
Im besonderen bei Filtern, die aus einer Mehrzahl von reihenweise in Gruppen angeordneten Schläuchen bestehen, würde dies, wenn man die Reinigung jeder Gruppe von der der anderen Gruppe unabhängig machen will, eine besondere Abschlußeinrichtung für jede Absaugeleitung bedingen. In particular with filters that consist of a plurality of rows There would be hoses arranged in groups, this would if one were cleaning wants to make each group independent of that of the other group, a special closure device condition for each suction line.
Gegenstand der Erfindung ist die Abstellung dieses Übelstandes durch Anordnung eines festen Stutzens am oberen Ende jedes Schlauches, der in der oberen Grenzstellung des Ringkanals dessen Saugöffnung verschließt. The object of the invention is to remedy this drawback Arrangement of a fixed nozzle at the top of each hose, which is in the upper Limit position of the ring channel closes the suction opening.
Durch diese Ausbildungen brauchen die einzelnen Filtergruppen nicht mehr durch Zwischenwände getrennt zu werden; auch fällt das Abschalten einer in der Abreinigung befindlichen Filtergruppe von der Saugwirkung der Filteranlage fort. Due to this training, the individual filter groups do not need to be separated more by partitions; switching off one also falls in the filter group located after the cleaning away from the suction effect of the filter system.
Die Zeichnungen stellen ein Ausfübrungsbeispiel dar. Abb. 1 zeigt das Filter im Aufriß, wobei der Längsschnitt durch den Unterbau und durch das Gehäuse gelegt ist (Linie A-B- nach Abb. 2). Abb. 2 zeigt das Filter im Querschnitt, und zwar im Schutt durch den Unterbau und durch das Gehäuse (Linie C-fl' nach Abb. I). Abb. 3 zeigt den Grundriß im Schnitt nach der Linie E-F (Abb. 2). The drawings represent an exemplary embodiment. Fig. 1 shows the filter in elevation, the longitudinal section through the substructure and through the housing is laid (line A-B- according to Fig. 2). Fig. 2 shows the filter in cross section, and in the rubble through the substructure and through the housing (line C-fl 'according to Fig. I). Fig. 3 shows the plan in section along the line E-F (Fig. 2).
Die im Filter reihenweise, senkrecht angeordneten, oben und unten offenen Schläuche a bilden zu zwei oder mehreren Reihen eine Filtergruppe. Jeder Schlauch ist an seinem oberen Ende auf einem Stutzen b staubdicht befestigt, dessen freie Öffnung in den Saugkanal c mündet. Die untere freie Öffnung mündet ebenfalls staubdicht auf einem Stutzen d, dessen freie Öffnung auf einem für eine Reihe Schläuche vorgesehenen Einsatzrumpf e angeordnet ist. Those arranged vertically in rows in the filter, above and below open hoses a form a filter group in two or more rows. Everyone Hose is attached dust-tight at its upper end on a nozzle b, the free opening opens into the suction channel c. The lower free opening also opens dust-tight on a nozzle d, the free opening of which on one for a number of hoses provided hull e is arranged.
Jede beispielsweise aus zwei Reihen Schläuchen a bestehende Filtergruppe ist außen von zusammenhängenden Ringkanälenf umgeben, welche durch eine gemeinsame Spindel, die von einer auf der Decke befindlichen Schaltvorrichtung h betätigt wird, an den Schläuchen periodisch auf und ab geführt werden. Jeder Ringkanal ist innen auf der der Schlauchwandung zugekehrten Seite auf seinem ganzen Umfang mit einem Schlitz versehen, durch den der an den Schläuchen haftende und in die Poren eingedrungene Staub abgesaugt wird. Die oberen Schlauchbefestigungsstutzen b sind so ausgebildet, daß sie einen in den Filterschlauch hineinragenden geraden Teil besitzen, auf welchen sich beim Hochführen die Ringkanäle/ schieben. Nach der Art der Schaltvorrichtung für die Bewegung der Spindel können diese Stutzen auch an jeder beliebigen Stelle des Schlauches angeordnet sein. Each filter group consisting, for example, of two rows of hoses a is surrounded on the outside by contiguous ring channels, which are connected by a common Spindle that is operated by a switching device h located on the ceiling, periodically up and down the hoses. Every ring channel is inside on the side facing the hose wall over its entire circumference with a Provided a slot through which the sticking to the tubes and penetrated into the pores Dust is extracted. The upper hose attachment nozzles b are designed in such a way that that they have a straight part protruding into the filter hose, on which the ring channels / slide when they are raised. According to the type of switching device These nozzles can also be used at any point to move the spindle be arranged of the hose.
Die durch den Sammelkanal i n in das Filter eintretende Staubluft wird zum Zwecke der Reinigung von außen durch die oben und unten offenen, auf den Stutzen b und d staubdicht befestigten Filterschläuche a nach innen gesaugt, wobei die mitgeführten Staubteilchen sich auf der Außenseite der Schläuche absetzen. Die Luft gelangt gereinigt in den Saugkanal c, aus dem die Reinluft abgesaugt wird. The dust air entering the filter through the collecting duct i n is used for cleaning from the outside through the open top and bottom Sockets b and d dust-tight attached filter hoses a sucked inwards, whereby the dust particles carried along settle on the outside of the hoses. the Cleaned air enters the suction channel c, from which the clean air is sucked off.
Nachdem die Schläuche genügend mit Staub beaufschlagt sind, werden durch die Schaltvorrichtung die Ringkanäle f nacheinander mittels der Spindel g an den Schläuchen a zum Zwecke der Abreinigung der Schläuche auf und ab geführt. After the hoses are sufficiently covered with dust, through the switching device the ring channels f one after the other by means of the spindle g on the hoses a for the purpose of cleaning the hoses up and down.
Um die durch die Ringkanäle abgesaugte Abreinigungsluftmenge gering zu halten, werden die Ringkanäle f nach der Abreinigungstätigkeit, die in durch das Schaltwerkh eingestellten Zeitabständen erfolgt, über in den Schläuchen angeordneten Blechstutzen b gezogen, die selbsttätig die freien Schlitzöffnungen der Ringkanäle verschließen und die Saugwirkung abschalten. Die teleskopartig aus- bzw. ineinander verschiebbaren Absaugerohre k der Ringkanäle münden in ein gemeinsames Sammelrohr l, aus dem die Abreinigungsluft abgesaugt wird. To the amount of cleaning air sucked through the ring channels low to keep, the ring channels f after the cleaning activity, which in through the switching mechanism takes place at set time intervals via arranged in the hoses Sheet metal socket b pulled, which automatically opens the free slot openings of the ring channels close and switch off the suction. The telescoping apart or into each other displaceable suction pipes k of the annular channels open into a common collecting pipe l, from which the cleaning air is extracted.
