A particle distribution device for disposing dirt particles deposited on analysis filter elements, in particular previously filtered out of a fluid volume flow, in an evenly distributed manner, said particle distribution device having a support unit which is realized for accommodating analysis filter elements having an upper particle receiving surface and which serves to accommodate and/or hold the analysis filter elements, the particle receiving surface being horizontally aligned, having wall elements which emerge, in particular monolithically, from the support unit, which laterally delimit the particle receiving surface in the accommodated state, which project in a vertical direction running vertically to the particle receiving surface beyond it and which serve to realize a receiving tub for a liquid, in particular water or cold cleaner, having flooding elements comprising a liquid reservoir which serve to submerge the analysis filter elements at least for a short time by flooding the receiving tub with the liquid in a flooding operating mode in order to float the dirt particles which are, in particular inhomogeneously, distributed on the particle receiving surface, and having liquid removal elements comprising a collection unit or draining elements and serving to discharge the liquid dammed up in the receiving tub, the liquid flowing through the analysis filter elements to retain the particle receiving surface, the support unit, the wall elements, the flooding elements, the liquid removal elements and the analysis filter elements being disposed in a common surrounding housing or a common module unit in the accommodated state, the liquid removal elements comprising a vacuum pump or a water jet pump for drawing off the liquid held in the receiving tub in such a manner that the liquid flows through the analysis filter elements during drawing off so that the dirt particles are retained on the particle receiving surface, characterized in that the liquid removal elements have an actuating unit, the actuating unit being realized in such a manner that, after the drawing off of the liquid for a short time in an initialization phase, a particle separating phase, which is realized by an opposite pumping operation of the vacuum or water jet pump, is activated for generating air bubbles in the liquid received in the receiving tub before, then, the liquid is, in particular completely, discharged from the receiving tub in a discharging phase. having wall elements which emerge, in particular monolithically, from the support unit, which laterally delimit the particle receiving surface in the accommodated state, which project in a vertical direction running vertically to the particle receiving surface beyond it and which serve to realize a receiving tub for a liquid, in particular water or cold cleaner, having flooding elements comprising a liquid reservoir which serve to submerge the analysis filter elements at least for a short time by flooding the receiving tub with the liquid in a flooding operating mode in order to float the dirt particles which are, in particular inhomogeneously, distributed on the particle receiving surface, and having liquid removal elements comprising a collection unit or draining elements and serving to discharge the liquid dammed up in the receiving tub, the liquid flowing through the analysis filter elements to retain the particle receiving surface, the support unit, the wall elements, the flooding elements, the liquid removal elements and the analysis filter elements being disposed in a common surrounding housing or a common module unit in the accommodated state, the liquid removal elements comprising a vacuum pump or a water jet pump for drawing off the liquid held in the receiving tub in such a manner that the liquid flows through the analysis filter elements during drawing off so that the dirt particles are retained on the particle receiving surface, characterized in that the liquid removal elements have an actuating unit, the actuating unit being realized in such a manner that, after the drawing off of the liquid for a short time in an initialization phase, a particle separating phase, which is realized by an opposite pumping operation of the vacuum or water jet pump, is activated for generating air bubbles in the liquid received in the receiving tub before, then, the liquid is, in particular completely, discharged from the receiving tub in a discharging phase.
