Description
Vorrichtung zum Reinigen des Schleifersteines an Holzschliff-Pressenschleifern Bei den bekannten Pressenschleifern zur Herstellung von Holzschliff war es schwer möglich, die Räume zwischen den Preßkästen ununterbrochen von Holzspänen und -splittern frei zu halten.Device for cleaning the grinding stone on wood pulp press grinders It was difficult with the known press grinders for producing wood pulp possible, the spaces between the press boxes uninterrupted by wood chips and splinters keep free.
Wenn auch die Holzspäne von Zeit zu Zeit entfernt wurden, was meistens bei Stillständen geschah, preßten sich doch die Späne steinhart zusammen, so daß die Schärfe des Schleifersteines beeinträchtigt wurde und das Spritzwasser den Stein niemals direkt reinigen konnte, da das Spritzrohr bei den bekannten Schleifern in der Mitte des Zwischenstückes und nicht getrennt von den Spänen angeordnet war.Even if the wood chips have been removed from time to time, which is mostly when it came to a standstill, the shavings were pressed together as hard as a rock, so that the sharpness of the grinder stone was impaired and the water splashed the stone could never clean directly, because the spray tube in the known grinders in was arranged in the middle of the intermediate piece and not separated from the chips.
Der Nachteil war, daß sich in kürzeren Zeitabständen der Stein durch die stärk zusammengepreßten Holzspäne-verschmierte, so daß er zur Vermeidung der Entstehung von Fasertrümmern und schlammigem Stoff öfters geschärft werden mußte. Durch die im folgenden beschriebene Vorrichtung sollen diese Nachteile behoben werden, so daß die Güte des Holzschliffes nicht mehr beeinflußt wird.The disadvantage was that the stone slipped through at shorter intervals the heavily compressed wood chips-smeared, so that he can avoid the Formation of fiber debris and muddy material often had to be sharpened. The device described below is intended to eliminate these disadvantages, so that the quality of the wood pulp is no longer influenced.
Abb. r stellt einen Teil eines Schleifersteines mit dem Zwischenstück nach der Erfindung dar.Fig. R shows part of a grinder stone with the intermediate piece according to the invention.
Das neue Zwischenstück besitzt zwei getrennte Räume, einen Raum d zum Aufstapeln von Spänen und einen Raume zur einwandfreien Bewässerung des Steines. Beide Räume werden getrennt durch eine verstellbare Platte f, die an der unteren Kante glatt oder verzahnt ist. Der Raum 'd besitzt nach der oberen Seite eine Klappe g, so daß es sehr leicht während des Fabrikationsprozesses möglich ist, die abfallenden Späne mit der Hand oder einer Zange zu entfernen. Es ergibt sich daraus,, daß eine gleichmäßige Reinigung des Steines von den abfallenden Spänen stattfinden kann. Der steinharte Druck der angesammelten. Späne unterbleibt, und die Schärfe des Steines wird nicht mehr beeinträchtigt. Das Spritzwasser bespült gleichmäßig den Stein, und ein normaler Fabrikationsprozeß setzt ein.The new intermediate piece has two separate rooms, a room d for stacking shavings and a room for proper watering of the stone. Both rooms are separated by an adjustable plate f, which is attached to the lower Edge is smooth or serrated. Room 'd has a flap on the upper side g, so that it is very easily possible during the manufacturing process to remove the falling Remove chips by hand or with a pair of pliers. It follows, that one even cleaning of the stone from the falling chips can take place. The rock-hard pressure of the accumulated. There are no chips and the sharpness of the stone is no longer affected. The splashing water washes the stone evenly, and a normal manufacturing process begins.
Abb. z stellt den Schnitt dar.Fig.z shows the section.
Das Zwischenstück kann auch an alten Schleifern angebracht werden, indem man den Schieber f zweiteilig, wie aus Abb. z ersichtlich ist, herstellt. An der Rippe h sind die Schleifkästen befestigt; dadurch muß der Schieber f in. zwei Teilen angefertigt werden.The adapter can also be attached to old grinders, by making the slide f in two parts, as can be seen in Fig. z. The grinding boxes are attached to the rib h; as a result, the slide f in. two parts can be made.
Bei neuen Schleifern ließe sich der Schieber durch entsprechende einfache Umänderung natürlich aus einem Stück herstellen.In the case of new grinders, the slider could be replaced by corresponding simple ones Of course, make the change out of one piece.
Es ist somit durch die Herstellung eines solchen Späneauswurfes mit in einem besonderen Raum befindlicher Wasserzuführung an Pressensclileiferri eine große Fehlerquelle beseitigt..It is thus with the production of such a chip ejection In a special room located water supply to press clileiferri one major source of error eliminated.
