In a device for pneumatically conveying powdery substances having a specific weight from 0.1 to 15.0 g/cm3 and a grain size in a range from 0.1 to 300 µm as conveyed goods through a filter in a tubular system, the ratio between the length (a) and the inner diameter (d) of a container (12) for temporarily receiving the conveyed goods and which contains a pump chamber (13) is higher than 0.5. In addition, the width of a filter arranged between a vacuum pump for aspirating the conveyed goods and the container (12) corresponds at the maximum to the cross-section determined by said diameter (d), the filter being designed as a plate-like filtering membrane placed in a filter insert in a replaceable manner.
Ce dispositif pneumatique sert à transporter des matières pulvérulentes d'un poids spécifique compris entre 0,1 et 15,0 g/cm<3>, en grains d'une taille comprise entre 0,1 et 300 mu m, comme milieu transporté à travers un filtre dans des systèmes tubulaires. Le rapport entre la longueur (a) et le diamètre intérieur (d) d'un récipient (12) qui reçoit temporairement le milieu transporté et qui contient une chambre de pompage (13) est supérieur à 0,5. En outre, la largeur d'un filtre situé entre une pompe à vide qui aspire le milieu transporté et le récipient (12) correspond à au maximum la section transversale déterminée par ledit diamètre (d), le filtre se présentant sous forme d'une membrane plate de filtrage montée échangeable dans une cartouche filtrante (26).
