Abstract
Abstract A silo, or bin, for flowable materials, especially heavy particulate solid materials. The bin has a bottom wall with a cylindrical wall upstanding therefrom. The bottom wall has a radial discharge opening formed therein and a rotor positioned above the bottom wall sweeps material into the opening. The bin has a guiding body on the axis which tapers in the downward direction and mounted inside the bin side wall are brake members which incline downwardly toward the axis of the bin and are preferably within the axial range of the guiding body.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
187 words
A bin or silo, for flowable solid materials comprising; a bottom wall, a side wall connected to and upstanding from said bottom wall, a discharge opening formed in said bottom wall, a rotatable discharge member in the bin above said bottom wall for moving material into said discharge opening, and at least one displacement body means supported in said bin above said discharge member and guiding surface means thereon inclined in the vertical direction, said body means being mounted on the axis of the bin and the guiding surface means thereon tapering outwardly in the downward direction and having a pointed upper end, support means adjustably supporting said body means on the axis of said bin and operable for tilting the body means about at least one axis extending transversely of the bin, said support means including a plurality of flexible elements connected to the lower end of said body means and extending upwardly therefrom, diverting members spaced about the upper end of the bin and about which respective ones of said elements are entrained, and pull members connected to said elements at the free ends thereof.
Claim 2
Dependent Claim
187 words
A bin or silo, for flowable solid materials comprising; a bottom wall, a side wall connected to and upstanding from said bottom wall, a discharge opening formed in said bottom wall, a rotatable discharge member in the bin above said bottom wall for moving material into said discharge opening, and at least one displacement body means supported in said bin above said discharge member and guiding surface means thereon inclined in the vertical direction, said body means being mounted on the axis of the bin and the guiding surface means thereon tapering outwardly in the downward direction and having a pointed upper end, support means adjustably supporting said body means on the axis of said bin and operable for tilting the body means about at least one axis extending transversely of the bin, said support means including a plurality of flexible elements connected to the lower end of said body means and extending upwardly therefrom, diverting members spaced about the upper end of the bin and about which respective ones of said elements are entrained, and pull members connected to said elements at the free ends thereof.
Claim 3
Dependent Claim
36 words
A bin according to claim 1 in which said discharge opening is in the form of a radial opening in said bottom wall, a trough underneath said opening, and a screw conveyor rotatable in said trough.
Claim 4
Dependent Claim
158 words
A bin, or silo, for flowable solid material comprising: a bottom wall, a side wall connected to and upstanding from said bottom wall, a discharge opening formed in said bottom wall, a rotatable discharge member in the bin above said bottom wall for moving material into said discharge opening, and at least one displacement body means supported in said bin above said displacement member and guiding surface means thereon inclined in the vertical direction, said body means being centrally mounted on the bin and the guiding surface means thereon tapering outwardly in the downward direction and having a pointed upper end, support means adjustably supporting said body means on said bin and operable for tilting the body means about at least one axis extending transversely of the bin, said support means including a plurality of pull elements connected to said body means at speced points and extending upwardly therefrom to a position for access externally of said bin.
Claim 5
Dependent Claim
158 words
A bin, or silo, for flowable solid material comprising: a bottom wall, a side wall connected to and upstanding from said bottom wall, a discharge opening formed in said bottom wall, a rotatable discharge member in the bin above said bottom wall for moving material into said discharge opening, and at least one displacement body means supported in said bin above said displacement member and guiding surface means thereon inclined in the vertical direction, said body means being centrally mounted on the bin and the guiding surface means thereon tapering outwardly in the downward direction and having a pointed upper end, support means adjustably supporting said body means on said bin and operable for tilting the body means about at least one axis extending transversely of the bin, said support means including a plurality of pull elements connected to said body means at speced points and extending upwardly therefrom to a position for access externally of said bin.
Claim 6
Dependent Claim
37 words
A bin according to claim 3 in which said side wall includes an enlarged section therein at the lower end, the upper end of which is within the range of the lower end of said body means.
Claim 7
Dependent Claim
36 words
A bin according to claim 4 in which the increase in area of the bin provided by said enlarged section is about equal to the amount of restriction of the bin provided by said body means.
Claim 8
Dependent Claim
33 words
A bin according to claim 3 including diverting members spaced about the upper end of the bin and about which pull members are entrained for change of position of said displacement body means.
Claim 9
Dependent Claim
24 words
A bin according to claim 6 including arresting and adjusting elements located externally of said bin to fix position of said displacement body means.
Claim 10
Dependent Claim
22 words
A bin according to claim 3 wherein said displacement body means has a height smaller than half the diameter of the bin.
Claim 11
Dependent Claim
39 words
A bin according to claim 3 wherein at least two braking devices are provided completely above said displacement body means, said braking devices projecting downwardly and being located across from each other at an inclined to said side wall.
Claim 12
Dependent Claim
12 words
A bin according to claim 9 wherein four brake bodies are provided.
Claim 13
Dependent Claim
30 words
A bin according to claim 9 wherein angle of inclination of said braking devices is smaller than angle of inclination of said guiding surface means on said displacement body means.
