Process for cleaning the dust filter of a silo by means of air blown in a shocklike manner into the filter hoses of a filter, whereby the cleaning process, according to which air is blown once into each filter hose when a pre-determined overpressure occurs in the silo, is carried out and repeated as long as this overpressure is still present in the silo and whereby air is blown in only one of several filter hoses at a time, the improvement being in that after the overpressure drops, at least one more cleaning cycle is carried out by blowing air in a shocklike manner into the filter hose against the walls of the hose.
In a device for cleaning the dust filter of a silo by means of air blown in a shocklike manner into the filter hoses of a filter whereby air is blown once into each filter hose when a pre-determined overpressure occurs in the silo and the cleaning process is carried out and repeated as long as overpressure is still present in the silo and whereby air is blown in only one of several filter hoses at a time, the improvement being in an air blasting nozzle being provided for and associated with each filter hose, means for blasting air from each of said nozzles only to its corresponding hose, and means for blasting air from said nozzles after the overpressure drops.
