A mobile discharging device for pneumatic handling of bulk goods, comprising a base frame (3) which is mounted on wheels (2) and on which there are arranged at least two containers (7a, 7b), an air unit (4), and a filter means (6) for removing particles carried by air evacuated from the respective containers (7a, 7b) in connection with application of a sub-atmospheric pressure in the same, said filter means (6) comprising at least one filter element (30) which is made of a fibre material. The air unit (4) allows application of a sub-atmospheric pressure in each of the containers (7a, 7b) for supplying bulk goods to the respective containers (7a, 7b) through a supply conduit (9) and applying a pressure above atmospheric in each of the containers (7a, 7b) for discharging bulk goods from the respective containers (7a, 7b) to a discharge conduit (23). The discharging device is characterised in that the filter means (6) is arranged outside the containers (7a, 7b), and that the filter means (6) communicates with the discharge conduit (23) through a clearing conduit (27) and comprises a means for releasing particles collected in said at least one filter element (30). The filter means (6) is arranged to collect the released particles in a bottom region (28) of the same and, when necessary, to discharge the same to the discharge conduit (23) through said clearing conduit (27). |
