摘要 PCT No. PCT/CH85/00167 Sec. 371 Date Jul. 21, 1986 Sec. 102(e) Date Jul. 21, 1986 PCT Filed Nov. 26, 1985 PCT Pub. No. WO86/03180 PCT Pub. Date Jun. 5, 1986.A device for the transportation of flowable material in pulverulent, granular, lump, granulated or pasty form in a feed pipe comprises a coaxial endless feeder screw which is rotatable in the forward or reverse direction and a drive mechanism for driving said screw. The drive mechanism enables one to obtain a feed motion without rotation and a rearward motion with a forced, regular rotation of the endless screw so that the material to be transported remains axially stationary during the rearward motion. Owing to the dense column of material to be transported the bearings may be suppressed; if they are provided, they will have to be arranged outside the conveying stock. The endless screw is designed as a single piece screw and the distance between the screw and the feed pipe is slightly bigger than the average size of the grains or lumps of material to be conveyed. The device is preferably used for the supply of pneumatic or hydraulic conveyors.
