Description

Zylindrisches oder pyramidenförmiges Schlauchfilter mit federndem Drahtgestell Bei den sehr verbreiteten Schlauchfiltern ist es bekannt, den aus Filterstoff bestehenden Schlauch dadurch in seiner Form aufrechtzuerhalten, daß er um ein aus schraubenförmig gewundenem Draht bestehendes, die Raumform des Schlauches bestimmendes Gestell gelegt ist. Demgegenüber besteht die Erfindung darin, daß der Filterschlauch durch einzelne, an seinem Umfange aufragende federnde Drähte in seiner Form aufrechterhalten wird, derart, daß die Drähte des Gesteller entsprechend der Gestalt des Filters die Kanten einer Pyramide oder die Erzeugende eines Zylinders bilden.Cylindrical or pyramid-shaped bag filter with a spring-loaded Wire frame In the case of the very common bag filters, it is known that made of filter material to maintain the existing hose in its shape by turning it off helically wound wire that determines the shape of the tube Frame is placed. In contrast, the invention consists in that the filter hose maintained in its shape by individual resilient wires protruding from its circumference is, such that the wires of the rack according to the shape of the filter form the edges of a pyramid or the generatrix of a cylinder.

Bei einer solchen Anordnung kann die Abreinigung des Schlauches in einfachster Weise dadurch erfolgen, daß auf die obere Fläche des Gestelles auf beliebige Weise ein Druck ausgeübt wird, durch den die federnden Drähte gebogen oder zusammengedrückt werden. Durch plötzliches Nachlassen schnellen dann die Windungen in ihre ursprüngliche Lage zurück, und der Filterstoff wird plötzlich angespannt, so daß eine nachdrückliche Abschüttlung des angesetzten Staubes erfolgt. With such an arrangement, the hose can be cleaned in The easiest way to do so is that on the upper surface of the frame on any Way a pressure is exerted by which the resilient wires are bent or compressed will. Sudden slackening causes the coils to revert to their original position Lay back, and the filter material suddenly becomes tense, so that an emphatic The deposited dust is shaken off.

In den Abb. 1 und 2 sind zwei Ausführungsformen eines solchen Filters als Beispiele dargestellt. Bei der Anordnung nach Abb. I bildet der Schlauch eine Pyratnide mit quadratischer Grundfläche und wird durch die federnden, die Kanten der Pyramide bildenden Drähten in seiner aufrechten Lage gehalten. Bei Herabdrücken der oberen Endfläche b zwecks Abreinigung biegen sich diese Drähte in die punktierte Lage durch. In Figs. 1 and 2 are two embodiments of such a filter shown as examples. In the arrangement according to Fig. I, the hose forms one Pyratnide with a square base and is made by the resilient, the edges the pyramid-forming wires held in its upright position. When pressed down the upper end surface b for cleaning purposes, these wires bend into the dotted Location through.

In Abb. 2 ist ein zylindrisches, durch einzelne Schraubenfedernc abgestütztes Schlauchgestell dargestellt. Liegt der Schlauch lose um die Drähte, so üben diese außerdem auch noch eine klopfende Wirkung auf ihn aus. Die Drähte können aber auch mit dern Stoff vereinigt sein.In Fig. 2 is a cylindrical, supported by individual coil springsc Hose rack shown. If the hose is loosely around the wires, practice them also a knocking effect on him. But the wires can also to be united with the matter.
