Abstract

The sealed drive for explosive material handling has a three part outer housing of stainless steel sealed by O-rings and screwed together. The housing has sealed chambers for the ball bearings carrying drive transmission (1,3) discs and opposing non-sealed drive receivers. The housing contains two round stainless steel different pole magnetic (2) rotors with a contact-less spacing. The gas and pressure sealed housing is attached directly to the material container (9).

Description

Der Zweck der Erfindung ist ein absolut gasdichtes Antriebssystem für die Reinigung von Behältern bzw. Silosysteme zu konzipieren, um eine Reinigung mit aggressiven, gasenden Medien mittels nachgeschaltetem rotierendem Sprühsystem zu ermöglichen.The purpose of the invention is an absolutely gastight drive system for the cleaning of To design containers or silo systems for cleaning with aggressive, gassing To enable media by means of a downstream rotating spray system.

Alle Elemente, bis auf die gummierten Magnete, sind aus säurebeständigem nichtmagnetischem V4A-Material (1.4571).All elements, except for the rubberized magnets, are made of acid-resistant, non-magnetic V4A material ( 1.4571 ).

Die Kraftübertragung vom Motor (6) zum Antrieb des Sprühkopfes erfolgt mittels wechselpolig in gerader Anzahl kreisförmig angeordneten Permanentmagneten (2) mit extrem hoher Magnetkraft. Die Anzahl und der Abstand der Magnete, bzw. der Durchmesser der Teilkreisanordnung bestimmt das zu erwartende Drehmoment (z. b. 14 Magnete, Abstand 4 mm auf Teilkreisdurchmesser 110 mm ergeben ein Drehmoment von 17,8 Nm).Power is transmitted from the motor ( 6 ) to the spray head by means of an even number of permanent magnets ( 2 ) with an extremely high magnetic force, arranged in an even number in a circle. The number and spacing of the magnets and the diameter of the pitch circle arrangement determine the expected torque (e.g. 14 magnets, spacing 4 mm to pitch circle diameter 110 mm result in a torque of 17.8 Nm).

Die Sprühkopfantriebswelle (4) ist mit dem magnetbestückten Antriebsteller (3) gelagert verbunden. Die Lagerung ist gegen grobe Verunreinigungen mit der Dichtung (7) geschützt. Darüber befindet sich eine aufgeschraubter, mit Dichtung versehender, Abdeckflansch (11). Die am Rohr aufgeschweißte Lageraufnahme (12), der Abdeckflansch (11) mit Dichtung (10), das Einleitrohr (13) mit angeschweißtem Spülmittelzufluß (14), der am Rohr angeschweißte Befestigungsflansch (8) mit dem am Behälter (9) angeschweißtem Flansch (16) und der Behälterdichtung (15) bilden somit ein absolut gas- und druckdichtes System.The spray head drive shaft ( 4 ) is connected to the magnetically equipped drive actuator ( 3 ). The bearing is protected against coarse contamination with the seal ( 7 ). There is a screwed-on cover flange ( 11 ) with a seal. The bearing receptacle ( 12 ) welded to the pipe, the cover flange ( 11 ) with seal ( 10 ), the inlet pipe ( 13 ) with welded detergent inflow ( 14 ), the mounting flange ( 8 ) welded to the pipe with the flange ( 6 ) welded onto the container ( 9 ) 16 ) and the container seal ( 15 ) thus form an absolutely gas and pressure-tight system.

Auf der Antriebsseite ist der Ex-geschützte Motor (6) mit Motorbefestigungsglocke und magnetbestücktem Antriebsteller (1) verbunden. Durch Betätigung des Motors wird der Abtriebsteller (1) in Rotation versetzt und überträgt die Drehbewegung über die Magnete (2) in wechselseitiger Nord-Süd-Polarität auf die Antriebswelle (4).On the drive side, the explosion-proof motor ( 6 ) is connected to the motor mounting bell and magnet-equipped drive plate ( 1 ). When the motor is actuated, the output actuator ( 1 ) is set in rotation and transmits the rotary motion to the drive shaft ( 4 ) in mutual north-south polarity via the magnets ( 2 ).
