Description
Ergänzungsblatt zur Patentschrift 372 967 klasse 50e Gruppe 4. Supplementary sheet to patent specification 372 967 class 50e group 4.
) Das Patent ist dadurch teilweise für nichtig erklärt, daß an Stelle der ersten vier Zeilen des Patentanspruchs die Bezeichnung II Druckschlauchfilter " tritt derart, daß der Patentanspruch mit den Worten beginnt: Drucks chlauchfilter, gekennzeichnet ..... Staubfilteranlage, in der die Staubluft durch eine zwischen Filtergehäuse und Staubluftleitung eingeschaltete Saung- oder Druckvorrichtung gedrückt wird Die Erfindung bezieht sich auf Stabfilteranlagen, also auf solche Einrichtungen zum Reinigen von staub, haltiger Luft oder Gasen, bei denen zwischen Filtergehäuse und Staubluftzuleitung eine Saug- und Druckvorrichtung (Gebläse) eingeschaltet ist, wobei also die Staubluft angesaugt und durch das Filtergehäuse hindurchgedrückt wird.) The patent is partially invalidated by the fact that in place the first four lines of the claim the designation II pressure hose filter "occurs in such a way that the claim begins with the words: pressure hose filter, marked ..... dust filter system, in which the dust air through a between Filter housing and dust air line activated suction or pressure device pressed The invention relates to rod filter systems, that is to say to such devices for cleaning dust, air or gases that are in between the filter housing and dust air supply line a suction and pressure device (fan) is switched on, So the dust air is sucked in and pushed through the filter housing will.
Gemäß der Erfindung ist an die Staubluftansaugleitung eine Zweigleitung angeschiossen, die unter Zwischenschaltung einer Umschaltklappe zum Lufteintrittsraum des Filtergehäuses führt, so daß man je nach Stellung dieser Umschaltklappe die Zweigleitung ein- oder ausschalten kann. Ist sie ausgeschaltet, so wirkt die Anlage in an sich bekannter Weise als Druckschlauchfilter. Ist die Zweigleitung indessen eingeschaltet und das Filtergehäuse ausgeschaltet, so werden die Filterschläuche von einem Gegenluftstrom durchströmt und dabei von dem anhaftenden Staub befreit. According to the invention, a branch line is connected to the dust air intake line shot, with the interposition of a switchover flap leads to the air inlet chamber of the filter housing, so that depending on the position of this Switching flap can switch the branch line on or off. Is it turned off the system acts in a manner known per se as a pressure hose filter. Is the Branch line, however, switched on and the filter housing switched off, so are the filter bags are traversed by a counter air flow and by the adhering Dust free.
In der Zeichnung ist ein Ausführungsbeispiel des neuen Umluftfilters dargestellt. In the drawing is an embodiment of the new air circulation filter shown.
Die Abb. 1 und 2 zeigen je einen senkrechten Schnitt durch das Filtergehäuse und Abb. 3 eine Vorderansicht. e (Abb. I und 2) sind die in das Filtergehäuse eingebauten Filterschläuche. Beispielsweise sind, wie aus Abb. 3 hervorgeht, vier Abteilungen I, 2, 3, 4 in dem Filtergehäuse vorgesehen, die die Filterschläuche enthalten, die in bekannter Weise oben geschlossen und unten offen sind. Die Filterschläuche sind mit einer Rüttel- oder Abklopfvorrichtung bekannter Art verbunden. Figs. 1 and 2 each show a vertical section through the filter housing and Fig. 3 is a front view. e (Fig. I and 2) are those built into the filter housing Filter bags. For example, as shown in Fig. 3, there are four departments I, 2, 3, 4 provided in the filter housing, which contain the filter bags, the are closed at the top and open at the bottom in a known manner. The filter bags are connected to a vibrating or knocking device of known type.
Das untere offene Ende der Filterschläuche mündet in den Fallrumpf h, und dieser steht wiederum mit einem besonderen Raum c neben dem Filtergehäuse in Verbindung, der eine Druckausgleichkammer bildet. Am unteren Ende dieser Druckausgleichkammer c ist für jede Filterabteilung ein Umschaltkasten d mit Umschaltklappe vorgesehen.The lower open end of the filter bags opens into the hull h, and this is in turn with a special space c next to the filter housing in connection, which forms a pressure equalization chamber. At the lower end of this pressure equalization chamber c a switch box d with switchover flap is provided for each filter department.
Die Druckausgleichkammer c steht mit der Saug-und Druckvorrichtung (Gebläse a) in Verbindung. b ist die zu diesem Gebläse führende Staubluftansaugleitung. Vor dem Gebläse mündet in diese Staubluftansaugleitung eine Zweigleitungg, die mit dem Umschaltkasten d verbunden ist. f ist der Abluftkanal. The pressure equalization chamber c is connected to the suction and pressure device (Fan a) in connection. b is the dust air intake line leading to this fan. In front of the blower, a branch line opens into this dust air intake line, which with the switch box d is connected. f is the exhaust duct.
Die Wirkungsweise ist folgende: Die Zweigleitungg kann mittels der Umschaltklappe d aus- und eingeschaltet werden. The mode of operation is as follows: The branch line can by means of the Switchover flap d can be switched off and on.
Die ausgeschaltete Stellung zeigt Abb. I.The switched off position is shown in Fig. I.
Hierbei wirkt die Anlage als Druckschlauchfilter, indem die Staubluft (oder Gase) mittels des Gebläses a durch die Leitung b angcsaugt, in den Druckausgleichraum c, den Raum h und von unten her durch die Filterschläuche c hindurchgedrückt wird. Die gereinigte Luft gelangt in das Filtergehäuze und strömt durch den Kanal f ab. Dieser gleiche Vorgang vollzieht sich bei entsprechender Stellung der Umschaltklappe in den sämtlichen vier Abteilungen des Filtergehäuses.The system acts as a pressure hose filter by removing the dust air (or gases) sucked in by means of the fan a through the line b into the pressure equalization chamber c, the space h and is pushed from below through the filter bags c. The cleaned air enters the filter housing and flows out through channel f. This same process takes place when the switchover flap is in the appropriate position in all four compartments of the filter housing.
Wird jedoch die Umschaltklappe d in einer Abteilung in die entgegengesetzte Stellung (Abb. 2) gebracht, so steht die Zweigleitung g nunmehr mit dem Lufteintrittsrauiu 1 des Filtergehäuses in Verbindung, während die Ausgleichkammer c abgeschaltet ist. Die Folge davon ist, daß die Filterschläuche der betreffenden Abteilung von einem Gegenluftstrom durchströmt werden, indem die Zweigleitung eine Saugwirkung in Richtung der in Abb. 2 eingezeichneten Pfeile ausübt. In Abb. 3 ist für die Abteilung des Filtergehäuses dieser Fall durch die eingezeichneten Pfeile veranschaulicht. However, if the changeover flap d in one department is in the opposite one Position (Fig. 2) brought, the branch line g is now with the Lufteintrittsrauiu 1 of the filter housing in connection, while the compensation chamber c is switched off. The consequence of this is that the filter bags of the department concerned by one Counter-air flow is flowed through by the branch line causing a suction in the direction the arrows shown in Fig. 2. In Fig. 3 is for the department of Filter housing this case is illustrated by the arrows shown.
Man kann eine selbsttätig wirkende Vorrichtung vorsehen, durch welche die Umschaltklappen d nacheinander in bestimmten Zeitabschnitten umgestellt werden. Diese Umstellvorrichtung kann auch gleichzeitig mit der Rüttel- oder Abklopfvorrichtung in Verbindung stehen. One can provide an automatically acting device through which the changeover flaps d can be switched over one after the other in certain time periods. This switching device can also be used at the same time as the vibrating or knocking device stay in contact.
