Definitions

  • the invention relates to a conveyor for fine-grained and / or powdery bulk material with the characteristics of The preamble of claim 1.
  • Conveyors of the type mentioned with a or two screw conveyors and one Funnels above the conveyor housing are available worldwide and therefore basically known.
  • the funnel points a circular funnel opening and a rectangular one in front the inlet opening of the housing of the conveyor Outlet opening. Between the two openings is the Funnel partly cylindrical and partly truncated pyramid and also has spherical interfaces.
  • the side walls of the housing for the conveyor are at Partly vertical and partly wedge-shaped.
  • the invention has for its object a conveyor of the kind of interest here, whereby the funnel is even more flowable guaranteed of poorly flowing bulk goods.
  • the invention provides the features of the characterizing part of claim 1 that the truncated pyramid-shaped wall pieces in the direction of the funnel axis and between the truncated pyramid-shaped wall pieces located, cross-sectionally curved wall pieces in the direction the funnel axis are significantly longer than the axial Length of the cylindrical wall piece.
  • funnels can be shorter than before.
  • the truncated pyramid-shaped, flat wall pieces and the between they are located, arcuate in cross section and in Developing approximately triangular wall pieces together with an integrated unit with the cylindrical wall piece optimal flow properties for the bulk material.
  • the flat wall pieces are about twice as long as so far and the arcuate in cross section, between the even wall pieces located around a Much longer and therefore steeper than the one in its place previously known, spherical wall pieces.
  • the different dimensions based on the funnel diameter required vary. Furthermore, the respective connection dimensions be different. Finally, there are variants also in that the cylindrical wall piece of the funnel have a tubular or flange-like connection or a flange and a frustoconical wall piece may include.
  • a conveyor 1 for fine-grained or powdery bulk material comprises a screw-like one Conveyor 2 with one or two screw conveyors 3, of which only one axis 3 'is indicated schematically in FIG. 1.
  • the screw conveyor 3 is located horizontally with its axis 3 ' Position in a housing 4, which is on its end faces for example vertical wall pieces 5 and 6 and in between wedge-shaped sloping wall pieces 7, 8 and at the bottom a wall pieces 7, 8 connecting partially cylindrical shell 9 comprises.
  • the one piece with each other and wall pieces 7, 8 connected to the shell 9 are schematically and dashed lines in Fig. 3.
  • the housing 4 with its vertical wall pieces 5 and 6 is also schematically shown in Fig. 2 for basic clarification and with different dimensions than shown in Fig. 1, as this applies to the representation of the housing 4 in Fig. 3.
  • a drive for one or two screw conveyors 3 in extension of their axis or axes 3 'according to Fig. 1 motor located in a housing 10 and optionally a gearbox that can also be used to drive when required serve an agitator 11, of which also only in Fig. 1 an agitator axis 11 'is shown.
  • An essential component of the conveyor 1 is the funnels 12 arranged above the housing 4 of the conveyor 2. It has a circular funnel opening 13 and in cross section square outlet opening 14, the shape and clear width of the rectangular inlet opening 15 in the housing 4 corresponds.
  • the funnel 12 In the region of the end 16 having the funnel opening 13 the funnel 12 has a cylindrical wall piece 16 '. Between the cylindrical wall piece 16 'and the square The outlet opening 14 consists of the funnel 12 of approximately truncated pyramids Wall pieces 17 and arranged between them, in cross-section arcuate partition pieces 18. The flat, truncated pyramid-shaped wall pieces 17 are large and clear in the direction of the funnel axis 19 longer than the cylindrical wall piece 16 '(Fig. 2).
  • Partition wall pieces 18 are arcuate in cross section Partition wall pieces 18. They are large and in the direction of the funnel axis 19 much longer than that cylindrical wall piece 16 '(Fig. 4). They are being processed Partitions 18 approximately triangular and have a narrow Late 20s on. In cross section, the narrow end 20 is almost channel-like or channel-like. Together with the narrow end 20, the intermediate wall pieces 18 are basically the same long as the truncated pyramid-shaped wall pieces 17.
  • Each two truncated pyramid-shaped Wall pieces 17 are flat over their entire length. At her lower edge 21 close the front arranged Wall pieces 5 and 6 of the housing 4 (Fig. 2).
  • the wall pieces 17 and 17 ' are inclined. Basically this also applies to the arcuate in cross section Partitions 18, but these are to the funnel axis 19th much less inclined, as is the angle a in Fig. 4 shows.
  • a flange 25 is also indicated on the right in FIG. 4, which can limit the funnel opening 13.
  • cylindrical wall piece 16 ' can also be conical Wall piece 26 are.
  • the truncated pyramid-shaped wall pieces 17 and 17 'and the between them, arcuate in cross section Intermediate wall sections 18 either have straight boundary lines 27, as shown in Figures 2 and 3 is.
  • the boundary lines 27 can also in principle be slightly arched.
  • the cross section is arcuate Partitions 18 at the four corners of the rectangular Exit opening 14 with arcuate boundary lines form a channel or channel-shaped contour.
  • the funnel 12 is finally expediently produced from a circuit board with several forming steps finally the shape shown in the figures receives.
  • Metal is used as the material. Because of the high The material must be annealed.
