The invention discloses a swing type distributing device. The distributing device comprises a box body (6), a chute (17), a beta-angle transmission assembly and an alpha-angle transmission assembly, wherein the lower part of the chute (17) is connected with a rotating support (18) arranged on the box body (6), and the upper part of the chute (17) is connected with a driving connecting assembly; the beta-angle transmission assembly is connected with the driving connecting assembly and can drive the chute (17) to rotate by the aid of the driving connecting assembly so as to adjust the beta angle of the chute (17); the alpha-angle transmission assembly is connected with the driving connecting assembly and can drive the chute (17) to tilt by the aid of the driving connecting assembly so as to adjust the alpha angle of the chute (17). According to the swing type distributing device, the alpha-angle motion of the chute is driven by the aid of hydraulic cylinders, the beta-angle motion of the chute is driven by the aid of a gear motor, and fixed-point, annular, sector-shaped and spiral distribution by the chute can be realized through separate or combined control.

Swing type distributing device

A delivery device for delivering filler material into a blast furnace, comprising: - a housing provided with a transition channel (1) for the filler material which defines a first axis X; - a chute (25) for the filler material arranged underneath said transition channel (1); - first actuating means (2), defining a respective second axis A parallel to the first axis X, to actuate a till of the chute (25) with respect to the first axis X; - second actuating means (3), defining a respective third axis Η parallel to the first axis X, to actuate a rotation of the chute (25) about said first axis X; - a first annular body (8) inside said housing and coaxial to the first axis X, adapted to translate along the first axis X by means of said first actuating means; - a second annular body (7) inside said housing and coaxial to said first axis X, adapted to translate along the first axis X being coupled to the first annular body (8) and/or adapted to rotate about the first axis X by means of said second actuating means; - a mechanism (10) coupled to the second annular body (7) and to the chute (25), adapted to convert a translations] motion о і the second annular body (7) into a tilling movement of the chute (25) with respect to the first axis X, and adapted to convert a rotation motion of the second annular body (7) into a rotation movement of the chute (25) with respect to the first axis X, and adapted to convert a rotation motion of the second annular body (7) into a rotation movement of the chute (25) with respect to the first axis X

Device for delivering filler material into a blast furnace

A delivery device (1) for delivering stock material into a blast furnace, the delivery device (1) comprising - a transition channel (3) for the stock material, defining a first axis (Y); - a chute (5) for delivering the stock material, arranged below the transition channel (3); - a first annular body (60), coaxial to and outside the transition channel (3), adapted to rotate about the first axis (Y); - a second annular body (10), coaxial to and outside the first annular body (60), adapted to translate along the first axis (Y) with respect to said first annular body (60) and/or to rotate about the first axis (Y) together with said first annular body (60); - at least one fixed rack (11, 12) fixed to the second annular body (10) and arranged parallel to the first axis (Y); - two shafts (21, 22), having a same second axis (X), transversal to said first axis (Y), arranged on opposite sides with respect to the transition channel (3) and crossing said second annular body (10) and said first annular body (60); - at least one toothed wheel (31, 32), engaging the at least one fixed rack (11, 12) and fixed to one shaft (21 ) of said two shafts (21, 22); wherein the chute (5) is connected to the two shafts (21, 22); whereby, when the second body (10) translates along the first axis (Y), the at least one fixed rack (11, 12) rotates the at least one toothed wheel (31, 32) and the respective shaft (21, 22) about the second axis (X), thus causing a change in the inclination of the chute (5) with respect to the first axis (Y).
