Abstract

A cellular wheel sluice for granulate bulk product has a housing in which a cellular wheel is rotatably mounted. The housing has an inlet duct for the bulk product. At least two raised granulate roofs are arranged at the inlet duct. A granulate groove is arranged respectively at the transition between two granulate roofs and/or at the transition between one granulate roof and an inlet edge. The two granulate grooves in each case run together at an intersection point in the rotation direction of the cellular wheel.

First claim

What is claimed is:

1. A cellular wheel sluice for granulate bulk product, with a housing in which a cellular wheel is rotatably mounted, wherein the housing has an inlet duct for the bulk product, wherein at least two raised granulate roofs are arranged at the inlet duct, wherein a granulate groove is arranged respectively at least one of at the transition between two granulate roofs and at the transition between one granulate roof and an inlet edge, wherein two granulate grooves in each case run together at an intersection point in the rotation direction of the cellular wheel.

2. The cellular wheel sluice according to claim 1 , wherein a displacement angle α enclosed between one of the granulate grooves and a cellular wheel web is constant at least in portions irrespective of the rotary position of the cellular wheel.

3. The cellular wheel sluice according to claim 1 , wherein a displacement angle α enclosed between one of the granulate grooves and a cellular wheel web increases at least in portions in the rotation direction of the cellular wheel.

4. The cellular wheel sluice according to claim 3 , wherein for the displacement angle α: 30°≤α≤90°.

5. The cellular wheel sluice according to claim 1 , wherein each granulate groove has a constant cross-sectional area along the groove course.

6. The cellular wheel sluice according to claim 1 , wherein each granulate groove has an opening angle β oriented relative to an interior of the housing, wherein 80°≤β≤120°.

7. The cellular wheel sluice according to claim 1 , wherein each granulate groove has a demoulding chamfer ε facing an interior of the housing.

8. The cellular wheel sluice according to claim 1 , wherein deflection edges of the granulate roofs have the same lengths l.

9. The cellular wheel sluice according to claim 8 , wherein deflection edges of the granulate roofs are evenly distributed in a transverse direction which is oriented parallel to the rotation axis of the cellular wheel.

10. The cellular wheel sluice according to claim 1 , wherein a lateral distance A of deflection edges of the granulate roofs from the inlet edge is greater than the length l of the deflection edges.

11. The cellular wheel sluice according to claim 1 , wherein each granulate roof is tilted continuously relative to a vertical plane.

12. The cellular wheel sluice according to claim 11 , wherein each granulate roof extends up to a cylinder bore of the housing.
