Abstract

1,201,004. Oscillating sieves, pneumatic separators; rotary disc filter. A. E. HOFFMAN K.G. MASCHINEN-UND MUHLENBAU. 18 Dec., 1968, No. 60219/68. Headings B2H and B1T. To clean combine harvested grain, it is fed from a hopper 2 on to an endless band sieve 3 oscillated by a rotating shaker 5. Large impurities fall into a chamber 12 at the end of the sieve belt and those particles which adhere to the belt are removed by a brush 23. After falling through the sieve, the grain, still containing fine and light impurities, is subjected to a transverse air current 17 produced by a suction fan 16. The fine and light impurites are entrained in the air current and are removed from the air by deposition on an air-permeable rotating filter disc 9. The filter disc has a rim 25, a hub 24 and three sections separated by radial vanes 21 (see Fig. 2). A filter gauze 18 covers all three sections. In operation, only part of the filter disc is within the air-stream containing the fine and light impurities; the other part depends into a chamber 11 where the impurities fall or are brushed off the filter gauze. The vanes 18 act as seals between the chamber 11 and air-stream passage 19. Large and fine impurities are removed through airlocks 13, 14.
