Title: Dust filter for gases - with rotary valve for alternately connecting a cleaning nozzle moving over the filter surface to compressed air and vacuum
Inventor: DANISCH HANS JOACHIM
IPC: B01D46/00
Filed: 1975-10-15
Abstract: A filter for dust-laden gases, partic. a bag filter has a filter surface in the filter housing sepg. a dust sepg. chamber from a clean gas chamber. A cleaning nozzle travels over the filter surface in the clean gas chamber and can be connected alternately via a rotary disc with a gas suction source, particularly the clean gas chamber and a flushing air fan. The rotary disc has an eccentric aperture supported for rotation round an axis perpendicular to its plane, so that it traverses the connecting pipes of the cleaning nozzle with the clean gas suction source and the flushing air respectively and seals these from the environment and thereby alternately shuts off and opens the connections as it rotates. The connecting pipes are placed diametrically opposite to one another relative to the axis of rotation of the disc. The improved filter is of simple and robust construction taking up a min. amt. of space and requires a less powerful drive motor for the disc than that used for rotating the vanes in the known equipment. A number of cleaning nozzles can be used with only one suction source and one flushing air fan.
