Definitions

  • the invention relates to a device suitable for drying bulk goods, which device is provided with at least one chamber comprising a bottom, which bottom is provided with a number of parallel tubes extending along central axes, which are provided with air passages present in the walls thereof, which bottom is furthermore provided with means for releasing and closing openings present in the bottom.
  • each chamber being provided with a bottom.
  • Each bottom is provided with a number of horizontally extending tubes and plate-shaped elements disposed between said tubes.
  • Present between the plate-shaped elements are openings, which are located under the tubes in a first position, in which the openings are closed.
  • the openings will be positioned beside the tubes, seen in horizontal direction, with the bulk goods present on the plates falling through the openings. Because a plate is in its entirety moved under a tube, all the bulk goods present on a plate will be pushed into the openings by the tubes.
  • the tubes are provided with air passages for supplying a gaseous fluid by means of which the bulk goods are dried, such as air, to the bulk goods.
  • the gaseous fluid will mainly reach the bulk goods that are located closest to the tubes.
  • the bulk goods that are located centrally between the tubes will hardly be reached by the gaseous fluid.
  • the object of the invention is to provide a device in which the bulk goods can be provided with a gaseous fluid over substantially the entire bottom.
  • the tubes provided with air passages are tiltable about central axes extending through the tubes between a first position, in which the openings are closed, to a second position, in which the openings are released, and vice versa.
  • the entire bottom is preferably provided with tubes. This makes it possible to provide the entire layer of bulk goods with air in a uniform manner. It is also possible, of course, to pass another gaseous fluid through the passages.
  • the cross-sectional configuration of the tubes is selected so that the tubes close the openings in the first position, whilst in the second, tilted position openings are present between the tubes, through which the bulk goods can fall.
  • One embodiment of the device according to the invention is characterized in that the cross-sectional area of an air passages space in the tube decreases from the first end.
  • FIG. 1 shows a device 1 according to the invention, which comprises a vertically extending cylinder 2, in which substantially horizontally extending bottoms 3a-3h are present. Chambers 4 are present between the bottoms 3a-3h and above the uppermost bottom 3a. Present below the lowermost bottom 3h is a discharge funnel 5.
  • Each bottom 3a-3h includes a number of horizontally extending tubes 6, which are tiltable in the directions indicated by the arrows P1, P2 about axes 7 extending through said tubes 6.
  • the tubes 6 of successive bottoms 3a-3h are alternately rotatable in directions indicated by arrows P1, P2.
  • the device 1 furthermore comprises a bulk goods supplying device 8, which includes an horizontally extending plate 9.
  • the plate is circular in shape and extends transversely to a central axis 10.
  • the plate 9 is rotatable about the central axis 10.
  • the plate 9 is provided with a rod 11 extending along the central axis 10, which is mounted in bearings in a bearing block 12 on a side of the plate 9 remote from the bottom 3a and which is rotatably connected to a motor 13.
  • the bearing block 12 is mounted in a frame 14, which is rotatably mounted, about an axis of rotation 15, in a bearing block 16.
  • the central axis 11 and the axis of rotation 15 extend parallel to each other in spaced-apart relationship.
  • the bulk goods supplying device 8 furthermore includes a supply pipe 17, which opens above the plate 9 with a first end 18 and which is connected to the frame 14 near the axis of rotation 15 with a second end 19 remote from the first end 18.
  • a supply pipe or feed hopper (not shown), via which the bulk goods are introduced into the second end 19, is disposed above said second end 19.
  • Figure 2 is a sectional view along the central axis 7 of a tube 6, which tube 6 is provided, near a first end 30 thereof, with a stationary propeller 31 and a diffuser 32 disposed some distance away therefrom.
  • the first end 30 is connected to an air supplying device (not shown), by means of which area is carried to the propeller 31 in a direction indicated by the arrow P10.
  • a plate 33 is disposed inside the tube 6, which plate includes an acute angle with the central axis 7.
  • the plate 33 is connected to a wall portion 35 of the tubes 6 near a second end 34 remote from the first end 30. Near the first end 30, the plate 33 is connected to a wall portion 36 extending parallel to the first wall portion 35.
  • the first wall portion 35 is provided with a number of air passages 37 which are regularly distributed over the surface of the wall portion 35.
  • Air that is blown into the tube 6 by the propeller 31 lands in the air passage space 38 bounded by the first wall portion 35 and the plate 33, from where the air is blown in the direction indicated by arrows P11, towards and through the bulk goods present on the first wall portion 35, via the air passages 35.
  • the cross-sectional area of the air passage space 38 decreases from the first end 30 to the second end 34. In this manner it is ensured that substantially the same amount of the air is passed through the air passages 37 located near the second end 34 as through the air passages 37 located near the first end 30.
  • the first wall portion 35 has a width B1 greater than the width B2 of the second wall portion 36.
  • the wall portions 35, 36 are interconnected by means of the wall portions 39, 36, which, as a result of the difference in width between the wall portions 35, 36, include an acute angle with the first wall portion 35.
  • the tubes 6 will be tilted through an angle of, preferably, 90° in the direction indicated by the arrows P1 or P2. In that case the tubes 6 take up a width in horizontal direction which equals the distance B3 between the first wall portion 35 and the second wall portion 36. Thus an opening which equals B1-B3 has been formed between the tubes 6.
  • the bulk goods present thereon will slide off the first wall portions 35 and fall through the openings present between the tubes 6 into a chamber disposed thereunder.
  • the bulk goods will successively land on the bottoms 3c-3h and eventually leave the device 1 via the funnel 5.
  • first wall portion 35 slightly curved instead of flat.
  • the surfaces 36, 39, 40 can have a circular or other shape.
