Abstract: A cleaning device for bag filters, comprising a cleaning head which is connected via a pressure fluid hose to a pressure medium source and has a cleaning bore, which can be rotated about a main axis of the cleaning head around and exits through the pressure medium, and with a control device for controlling operating parameters, is characterized in that the cleaning head is connected via a drive shaft with a drive device which sets the cleaning bore in rotation, wherein the control device also controls the drive means.

Abstract: A cleaning device (1) for hose filters comprising a cleaning head (5) having at least one nozzle (11) rotating about a longitudinal axis (L), is characterized in that the cleaning head (5) comprises a fixed jacket (15) having a smooth outer surface which surrounds the at least one rotating nozzle (11) at a distance and in which a series of through holes (17) are formed, said holes being distributed over the circumference of the jacket (15) and being arranged with respect to each nozzle (11) such that a jet emerging from each nozzle (11) during operation can pass through a through hole (17) at least intermittently.

Abstract: A suction cup for a mobile cleaning device for cleaning a hose filter. The suction cup has a base body with an outer circumference secured with respect to the hose filter. And, the suction cup has a through-opening with an inner circumference and a longitudinal axis. The suction cup also has a first felt seal secured with respect to the base body outer circumference, and a second felt seal secured with respect to the through-opening inner circumference.

Abstract: A filtration device having at least one filter bag between a crude gas side and a clean gas side, and a cleaning device for cleaning the filter bag. Each filter bag has a bag body with a longitudinal axis and a first end with a bag opening. The cleaning device has a nozzle head with a plurality of nozzles, the operation of which causes the cleaning device to rotate, and wherein the cleaning device can be moved in the longitudinal direction of each filter bag during operation of the nozzles. During the operation of the nozzles, the cleaning device generates a pressure wave in the bag body, and this pressure wave propagates from the bag opening to a free end of the bag body.
