Claims
- 1. An impact detacher for grain-like materials comprising:
- a centrifugal wheel which rotates about an axis;
- the wheel being enclosed within a housing; said housing having an annular impact ring;
- a concentric feed pipe for feeding materials to the wheel;
- said centrifugal wheel having a plurality of axially offset centrifugal conduits for the passage of the materials fed to the centrifugal wheel;
- a guiding apparatus being arranged within the centrifugal wheel for delivering the material to the plurality of axially offset centrifugal conduits;
- said annular impact ring including means, having a truncated cone section with two impact surfaces formed by two truncated cones opening in opposite directions, for allowing material passing through two of the plurality of axially offset centrifugal conduits to strike a respective one of said impact surfaces and to change direction resulting in two oppositely directed material streams;
- a product discharge conduit for receiving said material streams for discharging materials; and
- a product outlet being provided and associated with said discharge conduit,
- whereby product is discharged from the housing through said conduit and said product outlet.
- 2. The impact detacher of claim 1, wherein said guiding apparatus is connected with the centrifugal wheel.
- 3. The impact detacher of claim 1, wherein said guiding apparatus has a plurality of feed conduits which provide material to the centrifugal conduits, the centrifugal conduits being shaped like annular disks.
- 4. The impact detacher of claim 3, wherein the feed conduits open into the centrifugal conduit remote of the feed pipe and have an installation at the outer circumference, the installation narrowing in cross-section.
- 5. The impact detacher of claim 4, wherein the installation is arranged in the feed of the guiding apparatus and is constructed as an annular portion with a tapered shape toward the axis of rotation.
- 6. The impact detacher of claim 3, wherein the feed conduits are identical to one another and arranged symmetrically.
- 7. The impact detacher of claim 3, wherein the ratio of feed conduits delivering material to the inner conduit to the feed conduits delivering material to the outer conduit is about 1:2.
- 8. The impact detacher of claim 1, wherein said guiding apparatus comprises flat guide blades for delivering the material to the centrifugal conduits.
- 9. The impact detacher of claim 1, wherein an electric motor is flanged onto the housing of the impact detacher to effect rotation of the wheel.
- 10. The impact detacher of claim 1, wherein said product discharge conduit is formed from two halves having approximately the same shape, the discharge conduit being divided into two halves along a plane perpendicular to the axis of rotation of the wheel.
- 11. The impact detacher of claim 1, the impact detacher constructed having ventilation so that material feed and material discharge can be selected within a vertical plane as well as in a horizontal plane in all spatial directions.
- 12. The impact detacher of claim 1, wherein the change in direction is approximately 90 degrees.
- 13. The impact detacher of claim 1, wherein the impact ring substantially divides the housing into inner and outer cavities for the delivery of the impacted material to said product discharge conduit which further comprises inner and outer discharge conduit portions positioned tangentially to the wheel.
- 14. The impact detacher of claim 1 further wherein the product discharge conduit is an annular product discharge conduit.
- 15. The impact detacher of claim 14 wherein the product outlet is a tangential common product outlet.
- 16. The impact detacher of claim 1, wherein the housing has a second annular impact ring including means, having a truncated cone section with an impact surface formed by a truncated cone opening in one of the opposite directions, for allowing material passing through another one of the plurality of axially offset centrifugal conduits to strike the impact surface of the second impact ring and to change direction.
- 17. An impact detacher for grain-like materials comprising:
- a centrifugal wheel which rotates about an axis;
- the wheel being enclosed within a housing, said housing having a plurality of annular impact rings;
- a concentric feed pipe for feeding materials to the wheel;
- said centrifugal wheel having a plurality of axially offset centrifugal conduits for the passage of the materials fed to the centrifugal wheel;
- a guiding apparatus being arranged within the centrifugal wheel for delivering the material to the plurality of axially offset centrifugal conduits;
- each one of said plurality of annular impact rings including means, having at least one truncated cone section with at least one impact surface, for allowing material passing through a respective one of the plurality of axially offset centrifugal conduits to strike a corresponding impact surface and to change direction, said plurality of impact rings being configured such that their impact surfaces direct the impacted material in two opposite directions,
- a product discharge conduit for receiving said material streams for discharging materials; and
- a product outlet being provided and associated with said discharge conduit,
- whereby product is discharged from the housing through said conduit and said product outlet.
