Bale opener for biomass energy plants

摘要

Bale opener for use in a feeding line of a biomass energy plant, the bale opener (1) comprising at least two disintegration members (2), wherein each disintegration member (2) is rotatable around a respective rotation axis (5) and in the direction of that rotation axis (5) has a first end (3) and a second end (4), an inlet (17) for feeding bales (28) in a feeding direction (33) to the disintegration members (2), an outlet (18) for discharging loosened bale material from the disintegration members (2), a drive system (6) being operable to drive the disintegration members (2) to rotate around their respective rotation axis (5), wherein each disintegration member (2) is provided with a plurality of blades (8) that are radially disposed in a mill-wheel arrangement, the blades (8) extending outwardly from a radially inner edge (9) to a radially outer edge (10) and from a first edge (11) at the first end (3) of the disintegration member (2) to a second edge (12) in a direction towards the second end (4) of the disintegration member (2), and that the inlet (17) is arranged opposite to the first end (3) of the disintegration members (2) so as to feed the bales (28) to a processing region (34) at the first end (3) of the disintegration members (2).

1. Bale opener for use in a feeding line of a biomass energy plant, the bale opener (1) comprising
at least two disintegration members (2), wherein each disintegration member (2) is rotatable around a respective rotation axis (5) and in the direction of that rotation axis (5) has a first end (3) and a second end (4), an inlet (17) for feeding bales (28) in a feeding direction (33) to the disintegration members (2), an outlet (18) for discharging loosened bale material from the disintegration members (2), and a drive system (6) being operable to drive the disintegration members (2) to rotate around their respective rotation axis (5),
wherein each disintegration member (2) is provided with a plurality of blades (8) radially arranged around the rotation axis (5) such that a body of the blades (8) extend in an outward direction from the rotation axis (5) and in a direction along the rotation axis (5),the blades (8) extending outwardly from a radially inner edge (9) to a radially outer edge (10) and from a first edge (11) at the first end (3) to a second edge (12) in a direction towards the second end (4), wherein under operation the first edges (11) are moved in a direction of rotation of the disintegration members (2) so as to sweep the first edges (11) in a scraping movement across the cross-section of the bales (28), and that the inlet (17) is arranged opposite the first end (3) of the disintegration members (2) so as to feed the bales (28) to a processing region (34) at the first end (3) of the disintegration members (2).
