Definitions

  • the present invention relates to a device for preventing the bridge building of silo material in silo containers with at least one friction brake which is provided on the inner surface of the silo container and which includes a braking surface protruding into the silo container.
  • FIG. 1 diagrammatically illustrates a vertical section through a silo equipped with a device according to the invention.
  • FIG. 2 represents a section taken along the line IIII of FIG. 1.
  • FIGS. 3 and 4 respectively illustrate in view and top view a further embodiment of a friction brake according to the invention.
  • FIG. 5 is a view of still another friction brake according to the invention.
  • FIG. 6 is a top view ofFIG. 5.
  • the device according to the present invention is characterized primarily in that the marginal areas of the friction brake protruding into the silo container and adjacent to the inner wall of the container form obtuse angles with the inner wall of the container.
  • the material in the silo is prevented from depositing in the corners formed by the marginal area of the brake surface and the inner surface of the silo container.
  • the friction brake is so designed that its two lateral marginal areas converge in horizontal section in the direction to the center of the container;
  • the marginal areas similar to the central region form supporting surfaces which on one hand reduce the pressure of the material upon the container bottom and on the other hand prevent the formation of supporting bridges.
  • the marginal areas are located symmetrically with regard to the vertical central plane of the brake surface.
  • the lateral marginal areas of adjacent friction brakes which marginal areas face each other converge in horizontal section in the direction toward the center of the container while forming preferably acute angles with each other.
  • the lateral marginal areas of the friction brakes are plane. This greatly facilitates the manufacture and mounting of the friction brakes.
  • the lateral marginal areas of the friction brake form obtuse angles in the central region of the friction brake so that the entire braking surface can in a simple manner he made as a development.
  • the braking surface of the friction brake is expediently inclined downwardly toward the center of the container.
  • a plurality of braking surfaces in lateral spaced arrangement to each other are provided at different levels.
  • at least one friction brake may be provided approximately vertically above each conveying element.
  • the silo illustrated in FIGS. 1 and 2 comprises a silo container 1 with a cylindrical vertically arranged mantle 2 forming the inner surface 3 of the silo container 1.
  • the mantle 2 has its lower portion provided with a plane bottom 4 while its upper portion is provided with a conical cover wall 5 forming an obtuse angle.
  • a rotor 6 for rotation about the central axis of the silo container'l.
  • the circumference of the rotor 6 is equipped with tangentially arranged spring arms 7 located at different heights. The free ends of said arms 7 are located in the immediate vicinity of the inner surface 3 of the silo container 1.
  • the inner surface of the silo container 1 has connected thereto a plurality, for instance twelve, friction brakes 8-11 which are uniformly distributed over the inner circumferential surface of the container 1.
  • all friction brakes 8-11 are of identical design and are located in spaced relationship to each other. However, if
  • the friction brakes may also be of different.
  • Each friction brake 8, 9, l0, 11 is formed of sheet metal which is bent so as to have a wedge shape or the shape of a box and is connected to the inner surface 3 of the mantle 2 of the container 1 in any convenient manner, for instance, by welding.
  • the largest surface 12 of each of said friction brakes is directed toward the central axis of the silo container 1 and is arranged in a plane inclined to the axis in such away that the upper marginal area of this surface 12 is spaced from the central axis of the silo container 1 by a distance which is greater than the distance between the lower marginal area and the central axis of the container 1.
  • the upper marginal area of the surfaces 12 is directly adjacent the inner surface 3 of the mantle 2.
  • the lower marginal area of each braking surface 12 is formed by the corner zone between said surface and the bottom surface 13 of the respective pertaining friction brake, said bottom surface 13 being horizontal or perpendicular to the central axis of the silo container 1.
  • the friction brakes 8-11 are arranged at different levels on the silo mantle 2 in such a way that three 0065 2by making the angle defined by the two marginal areagroups are formed with respective adjacent friction of the braking surface greater than the arc angle of the braking surface. In order to assure a collapse of any brakes 8-11.
  • the friction brakes 8-11 of each group are arranged at equal vertical distances, these distances being greater than the height of the friction brakes. In this way the adjacent friction brakes 8, 1 1 of each two groups are vertically spaced to a greater extent than adjacent friction brakes 8, 9; 9, l; 10, 11 within the respective group. Furthermore, the arrangement is such that every three corresponding friction brakes 8, 9, 10, 11 offset by 120 with regard to each other are located at the same height.
  • the lowermost friction brakes 11 have a shorter vertical distance from the rotor 6 than the uppermost friction brakes 8 have from the ceiling wall of the container 1.
  • the width of the braking surfaces 12 of the friction brakes 8-11 and the number of the friction brakes are determined primarily by the size of the silo container 1; the angle of inclination of the braking surface 12 which may be different with regard to the friction brakes 8-11, and the radial extension of the braking surfaces 12 depend on the bulk weight and the moisture content of the material in the silo.
  • the material is within the region of the mantle 2 of the container braked by the friction brakes 8-11 so that the bridge formation will be prevented and the static bottom pressure of the silo material will be reduced.
  • each braking surface 2 has two lateral marginal areas 14 which in horizontal section merge at an obtuse angle with the area of the braking surface 12 therebetween. All areas 14, 15 of the braking surface are plane.
  • the marginal areas 14 are in view according to FIG. 1 and in top view according to FIG. 2 of triangular shape while the tips of the, triangles are with the smallest angle directed upwardly.
  • Each marginal area 14 extends with its edge .16 which faces away from the central region 15 to the inner surface 3 of the container mantle 2 so that also inwardly extending corners between the central region 15 of the braking surface 12 and the inner surface 3 are filled or bridged.
  • the marginal area 14 together with that section of the inner surface 3 ofthe container 2 which merges with the area 14 defines an obtuse angle 21 which opens toward the center of the container so that silo material which might pass into this corner zone will drop out.
  • the bottom side of the bottom 4 of the container 1 is equipped with three conveying devices 17 which are uniformly distributed over the circumference and which in the particular embodiment shown are formed by a conveyor worm 19 arranged in a worm trough 18.
  • the worms 19 extend radially with regard to the silo container 1 while above each conveyor worm 19 a corresponding opening 20 is provided in the bottom 4 of the container 1 through which opening the silo material drops into the respective worm trough 18.
  • the conveying devices 17 or frictionbrakes 811 are so arranged that those friction brakes l l which are located farthest downwardly are respectively located vertically above a conveyor worm 19.
  • the number of the groups of friction brakes thus corresponds to the number of the conveying devices 17 on the silo container 1.
  • the marginal areas 14 which face each other and respectively pertain to adjacent friction brakes are so arranged that in horizontal section they define an acute angle 22 which opens toward the center of the container.
  • the braking surface 12a may prismatically be so simplified that it is formed only by two surface sections which in horizontal section angularly merge with each other in a V-shaped manner. These surface sections form the central region and also the marginal regions 14a of the braking surface 12a which marginal regions 14a merge with the inner surface 3a of the mantle 20 at an obtuse angle. In this way the braking surface 12a forms with its upper end a wedge-shaped tip.
  • thetwo plane surface sections forming the braking surface 12:: are in horizontal section and in top view located at a right angle with regard to each other.
  • FIGS. 5 and 6 illustrate a modified friction brake in which the braking surface 12b is formed by the segment of a conical mantle surface the central axis of which expediently intersects the inner surface 3b of the mantle 2b at the upper tip 23 of the brake surface 12b and from there extends downwardly at an inclination in outward direction in such a way that at'the level of the bottom surface 13b of the friction brake it has a greater distance from the center of the mantle 2b.
  • the central axis of the conical segmental surface 12b which central axis is located in the axial plane of the mantle 2b is also provided with an acute angle with regard to thecentral axis of the mantle 2b.
  • the lateral zones of the conical mantle surface 12b form the marginal areas 14b which merge at an acute angle with the inner surface 3b.
  • An apparatus to assure against formation of bridges of fibrous silo material in a silo container having a substantially tubular upright portion with a bottom, which includes: multiple friction brake means with lateral marginal areas connected to the inner wall surface of said tubular portions so as to form obtuse angles therewith, and friction surface means inclined downwardly on each friction brake means, said lateral marginal areas extending along substantially the entire height of said friction surface means of respective friction brake means, said lateral marginal areas of adjoining friction brake means where directed toward each other extending in horizontal section in a directiontoward the middle of the silo container.
  • said friction brake means includes more than two friction brake bodies at substantially equal level, those lateral marginal areas which face toward each other when viewed in horizontal section diverging in the direction toward the central axis of the container.
