Description

Bei Scheidern aus gelochtem, nicht leitendem Blech, z. B. aus Hartgummi oder Celluloid, ist es häufig erwünscht, durch Anbringung von massiven oder hohlen Rippen oder durch Wellung der Bleche die Elektrodenplatten in dem erforderlichen Abstand voneinanderzuhalten. Die massiven Rippen, welche hierbei stets aus dem Stoff des Bleches bestanden, also nicht leitend waren, haben den Nachteil, größere TeileIn the case of separators made of perforated, non-conductive sheet metal, e.g. B. made of hard rubber or celluloid, it is often desirable by attaching solid or hollow ribs or by corrugation of the metal sheets to keep the electrode plates at the required distance from one another. The massive ribs, which always consisted of the material of the sheet, are not were conductive have the disadvantage of larger parts

ίο der Elektrodenplatten gegen den Stromdurch gang abzuschirmen und dadurch die Kapazität des Sammlers zu verringern. Die hohlen Rippen haben, falls sie selbst keine Öffnungen besitzen, denselben Nachteil, die mit Öffnungen versehenen haben nicht die Festigkeit gegen den Druck der sich evtl. krümmenden Elektrodenplatten, welchen Nachteil die gewellten Bleche in noch höherem Maße zeigen.ίο the electrode plates against the current shield aisle and thereby reduce the capacity of the collector. The hollow ribs if they have no openings themselves, have the same disadvantage as those provided with openings do not have the strength against the pressure of the possibly curved electrode plates, which is the disadvantage of the corrugated metal sheets show to an even greater extent.

Diese Übelstände werden nach der Erfindung dadurch vermieden, daß die gelochten Bleche mit Rippen aus porösem Stoff, vorzugsweise porösem Hartgummi, versehen und diese auf denr'gelochten Blech so befestigt werden, daß sie wenigstens in dem größten Teil ihrer Berührungsfläche nicht ihre Porösität verüeren, daß sie also vom Strom durchflossen werden können. Beispielsweise können auf ein flachgelochtes Hartgummiblech Rippen beliebigen, etwa rechteckigen Querschnittes an einzelnen Punkten ihrer Länge durch Asphalt o. dgl. aufgeklebt werden. Statt des Asphalts, also eines stromdurchlässigen Stoffes, kann das Aufkleben der Rippen durch einen porösen Stoff, etwa poröses Hartgummi, nach Patent 425 770 geschehen. Endlich können die Rippen durch eine Art Vernietung auf dem Blech befestigt werden, indem bei ihrer Herstellung ihr Material durch die Löcher des Bleches dringt. Dieselben Befestigungsweisen können auch bei gewellten Blechen oder solchen mit gelochten Hohlrippen Anwendung finden, wobei durch Ausfüllen einzelner Wellentäler oder der Hohlrippen durch die porösen Rippen das Blech gegen das Flachdrücken der Wellen oder Hohlrippen widerstandsfähig gemacht wird. Selbstverständlich können die Rippen sowohl an einer wie an beiden Seiten des Bleches angebracht werden.These inconveniences are avoided according to the invention in that the perforated sheets provided with ribs made of porous material, preferably porous hard rubber, and these on The perforated sheet metal are fastened in such a way that they at least over the largest part of their contact surface do not lose their porosity, so that the current flows through them can. For example, ribs can be placed on a flat-perforated hard rubber sheet. approximately rectangular cross-section at individual points along its length through asphalt or the like. Glued on will. Instead of the asphalt, i.e. a current-permeable material, the adhesive can be used of the ribs by means of a porous material, such as porous hard rubber, according to patent 425,770. Finally, the ribs can be attached to the sheet metal by a kind of riveting, using their material during their manufacture penetrates through the holes in the sheet metal. The same fastening methods can also be used for corrugated Sheets or those with perforated hollow ribs are used, whereby by filling individual corrugation troughs or the hollow ribs through the porous ribs the sheet metal is resistant to the flattening of the waves or hollow ribs is made. Of course, the ribs can be attached to one or both sides of the sheet.
