Description

Einrichtung zur Bespannung von Trommelfiltern mit Sieben oder Filtertüchern.Device for covering drum filters with sieves or filter cloths.

Bei Saugtrocknern kommt es sehr leicht vor, daß an den Längskanten der Trommeln die Siebe oder Filtertücher beim Anspannen abreißen. Diesem Übelstand soll nach vorliegender Erfindung am wirksamsten. dadurch entgegengetreten werden., daß in Vertiefungen der Trommelkanten, welche die Siebe oder Filtertücher zu passieren haben, sich drehende runde Körper, z. B. Rohre, Rollen o. dgl., angeordnet sind. Zur Spannung der Siebe oder Filtertücher sind in der Spannzelle der Filtertrommel zwei abgerundete Schienen angeordnet, die durch Gewindeschrauben angezogen werden können. Die Spannzelle der Trommel wird durch eine Holzleiste g abgedeckt, durch die nicht nur eine glatte Oberfläche des Trommelumfanges erzielt wird, sondern durch die zugleich das Sieb oder Tuch nach dem Spannen nochmals festgelegt wird. In the case of suction dryers, it can easily happen that on the long edges the drums tear off the sieves or filter cloths when tightening them. This evil is said to be most effective according to the present invention. be countered thereby., that in depressions of the drum edges, which the sieves or filter cloths to pass have rotating round bodies, e.g. B. pipes, rollers o. The like. Are arranged. To tension the sieves or filter cloths, the filter drum is in the tensioning cell two rounded rails arranged, which are tightened by threaded screws can. The tensioning cell of the drum is covered by a wooden strip g, through which not only a smooth surface of the drum circumference is achieved, but through which at the same time the sieve or cloth is fixed again after tensioning.

In der beiliegenden Zeichnung Ist die Einrichtung veranschaulicht. -In die Längskanten der Saugtrommel a sind Rohre b eingelegt, über welche das Sieb c geführt wird. The setup is illustrated in the accompanying drawing. -In the longitudinal edges of the suction drum a tubes b are inserted, over which the sieve c is performed.

Zur Siebbespannung selbst werden die beiden Enden des Siebes zwischen zwei Schienen d eingeklemmt, welche unten bei e stark gerundet sind. Um diese Rundungen wird das Sieb c herumgeführt. Die Schienen d werden durch Schrauben f in die vorgesehene Zelle an der Saugtrommel hineingezogen. To cover the sieve itself, the two ends of the sieve are between two rails d clamped, which are strongly rounded at the bottom at e. Around these curves the sieve c is passed around. The rails d are screwed into the provided Cell pulled in at the suction drum.

Diese Einrichtung verhllndert ein Abreißen der Siebbespannung in jeder Weise. Einmal ist der Schutz dadurch erzielt, daß an den Trommelkanten beim Anspannen des Siebes die Rohre b sich entsprechen, d drehen, also das Sieb sich rollt. An der Stelle e, wo das Sieb um die Spannschienen herumgeführt werden muß, sind diese sehr stark gerundet. This device prevents the screen covering from tearing off either way. Once the protection is achieved by the fact that at the drum edges Tighten the sieve, the tubes b correspond to each other, d rotate, so the sieve itself rolls. At point e, where the sieve must be guided around the tensioning rails, these are very rounded.

Es können aber an diesen Stellen ebenso, wie an den Trommelkanten, sich drehende Führungen, also Rollen oder Rohre, für das Sieb eingelegt werden. But at these points as well as at the drum edges, rotating guides, i.e. rollers or tubes, are inserted for the sieve.

Beim Spannen des Siebes durch Anziehen der Schrauben werden die Schienen in die an der Saugtrommel vorgesehene Zelle hineingezogen. Dadurch wird das Sieb ge--spannt, und zwar kann die Bespannung beliebig straff genzogen werden. When tensioning the screen by tightening the screws, the rails are drawn into the cell provided on the suction drum. This will make the sieve stretched, the covering can be pulled taut as required.
