Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bei den bisherigen geheizten Leder-Walkfässern wird zur Heizung Wasserdampf verwendet, wobei der Nachtheil eintritt, dafs das Leder an den auf den Wärmegrad des Dampfes erhitzten Flächen versengt wird. Bei dem nachstehend beschriebenen Walkfafs kann dieser Uebelstand nicht eintreten, weil zu seiner Heizung nicht Wasserdampf von über 100° Wärme, sondern nur warmes Wasser verwendet wird, dessen Temperatur nicht höher ist, als das Leder ohne Schaden erträgt, also etwa 40 °.In the previous heated leather fulling barrels, steam is used for heating, the disadvantage arises that the leather is affected by the degree of warmth of the steam scorched heated surfaces. With the Walkfafs described below, this can Bad situation does not occur because water vapor of over 100 ° is not used for its heating Warmth, but only warm water is used, the temperature of which is not higher than the leather can withstand without damage, so about 40 °.

Das neue Walkfafs besteht aus einer Trommel *a, deren Umfang durch einen ringförmigen Wasserheizmantel b gebildet wird, in welchen, wie die Pfeile andeuten, das Heizrohr an der einen Seite eintritt.The new fulling drum consists of a drum * a, the circumference of which is formed by an annular water heating jacket b , in which, as the arrows indicate, the heating pipe enters on one side.

Das Heizwasser wird in einem neben dem Walkfasse stehenden Wasserbehälter h auf den erforderlichen Grad erwärmt, und zwar durch Einführung von Dampf, oder durch Ofenheizung, oder durch irgend eine sonstige Heizeinrichtung ; sein Wärmegrad kann am Thermometer i erkannt werden. Aus dem oberen Theile des Wasserbehälters h strömt das Heizwasser durch das Rohr k, den Stopfbüchskörper g und die vier hohlen Arme d dem Heizmantel b zu, während das abgekühlte Wasser durch die vier hohlen Arme c, den Stopfbüchskörper f und das Rohr / in den Wasserbehälter zurückfliefst, um hier aufs Neue erwärmt zu werden. Die für diesen Kreislauf erforderliche Bewegung erhält das Heizwasser durch eine in das Rohr / eingeschaltete Wasserbewegungsvorrichtung m, als welche eine der bekannten Kreiselpumpen, eine Dampfstrahlpumpe oder dergleichen dient. The heating water is heated to the required degree in a water container h next to the drum, namely by introducing steam, or by furnace heating, or by some other heating device; its heat level can be seen on the i thermometer. The heating water flows from the upper part of the water tank h through the pipe k, the stuffing box body g and the four hollow arms d to the heating jacket b , while the cooled water flows through the four hollow arms c, the stuffing box body f and the pipe / into the water container flows back to be warmed up again here. The heating water receives the movement required for this cycle by a water movement device m connected into the pipe / which serves as one of the known centrifugal pumps, a steam jet pump or the like.

Mittelst einer im Rohr k angebrachten Drosselklappe oder sonstigen Absperrvorrichtung η kann der Durchströmungsquerschnitt für das Heizwasser verändert und dadurch die durchströmende Wassermenge und damit auch das Mafs der ins Walkfafs übertragenen Wärmemenge geregelt werden.The flow cross-section for the heating water can be changed by means of a throttle valve or other shut-off device η attached in the pipe k, thereby regulating the amount of water flowing through and thus also the amount of heat transferred into the fulling chamber.

Um eine energische Wärmeübertragung von dem Heizwasser an das Leder zu bewirken, ist der innere Blechmantel 0 des Walkfasses aus Wellblech hergestellt.In order to bring about an energetic transfer of heat from the heating water to the leather, the inner sheet metal jacket 0 of the drum is made of corrugated iron.
