Arrangement for piling a bulky material having different grain sizes

Claim 3

An arrangement for piling a bulky material which has different grain sizes and is supplied from above downwardly, comprising guiding means arranged to guide a flow of a bulky material downwardly; pile forming means including at least three passages with one passage located centrally and two other passages located laterally adjacent to said central passages at opposite sides of the latter; separating means located substantially below said guiding means and above said pile forming means and arranged to separate the flow of the bulky material into at least one coarse grain portion and two fine grain portions, said separating means including grate elements arranged so that the fine grain portions of the bulky material pass through said grate elements into and through a respective one of said lateral passages, whereas the coarse grain portion of the bulky material is guided over said grate elements to pass into and through said central passage so as to form a pile having at least one central pile zone composed of the coarse grain portion of the bulky material, and two lateral pile zones composed of the fine grain portions of the bulky material.

Claim 4

An arrangement for piling a bulky material which has different grain sizes and is supplied from above downwardly, comprising guiding means arranged to guide a flow of a bulky material downwardly; pile forming means including at least three passages with one passage located centrally and two other passages located laterally adjacent to said central passages at opposite sides of the latter; separating means located substantially below said guiding means and above said pile forming means and arranged to separate the flow of the bulky material into at least one coarse grain portion and two fine grain portions, said separating means including grate elements arranged so that the fine grain portions of the bulky material pass through said grate elements into and through a respective one of said lateral passages, whereas the coarse grain portion of the bulky material is guided over said grate elements to pass into and through said central passage so as to form a pile having at least one central pile zone composed of the coarse grain portion of the bulky material, and two lateral pile zones composed of the fine grain portions of the bulky material.

Claim 5

An arrangement as defined in claim 2, wherein said guiding means includes a saddle-like chute having two inclined portions each arranged to guide the flow of the bulky material toward a respective one of said lateral passages.

Claim 6

An arrangement as defined in claim 2, wherein said passages forming means includes an outer wall and two inner walls arranged so that each of said lateral passages is formed between said outer wall and one of said inner walls, whereas said central passage is formed inwardly of said inner walls.

Claim 7

An arrangement as defined in claim 4, wherein each of said grate elements extends between said outer wall and a respective one of said inner walls bounding a respective one of said lateral passages.

Claim 8

An arrangement as defined in claim 4, wherein said outer wall is formed as a hopper.

Claim 9

An arrangement as defined in claim 6, wherein each of said inner walls is formed as an insert in said hopper.

Claim 10

An arrangement as defined in claim 7, wherein each of said grate elements is fixedly connected with said hopper and a respective one of said inserts.

Claim 11

An arrangement as defined in claim 7, wherein each of said grate elements has two end portions spaced from one another, one of said end portions of each of said grate elements being fixedly connected with said hopper, whereas the other end portion of the same can swing freely.

Claim 12

An arrangement as defined in claim 7, wherein each of said grate elements has two end portions spaced from one another, one of said end portions of each of said grate elements being connected with a respective one of said inserts, whereas the other end portion of the same swings freely.

Claim 13

An arrangement as defined in claim 2, wherein said members of said grate elements are round bars.

Claim 14

An arrangement as defined in claim 2, wherein the bulky material flows from said guiding means toward each of said grate elements in a predetermined direction, each of said grate elements being composed of a plurality of members which are oriented in accordance with the direction in which the bulky material flows from said guiding means to the respective grate element.

Claim 15

An arrangement as defined in claim 11, wherein said members of each of said grate elements are arranged so that the distance between and the inclination of said members are variable.

Claim 16

An arrangement for piling a bulky material which has different grain sizes and is supplied from above downwardly, comprising a conveyor for conveying a bulky material with different grain size and having a discharge end; and a piling device suspended on said discharge end of said conveyor and including guiding means arranged to guide a flow of a bulky material downwardly; pile forming means with at least three passages with one passage located centrally and two other passages located laterally adjacent to said central passages at opposite sides of the latter, and separating means located substantially below said guiding means and above said pile forming means and arranged to separate the flow of the bulky material into at least one coarse grain portion and two fine grain portions, said separating means including grate elements arranged so that the fine grain portions of the bulky material pass through said grate elements into a respective one of said lateral passages, whereas the coarse grain portion of the bulky material is guided over said grate elements to pass into said central passage so as to form a pile having at least one central pile zone composed of the coarse grain portion of the bulky material, and two lateral pile zones composed of the fine grain portions of the bulky material.

Claim 17

An arrangement for piling a bulky material which has different grain sizes and is supplied from above downwardly, comprising a conveyor for conveying a bulky material with different grain size and having a discharge end; and a piling device suspended on said discharge end of said conveyor and including guiding means arranged to guide a flow of a bulky material downwardly; pile forming means with at least three passages with one passage located centrally and two other passages located laterally adjacent to said central passages at opposite sides of the latter, and separating means located substantially below said guiding means and above said pile forming means and arranged to separate the flow of the bulky material into at least one coarse grain portion and two fine grain portions, said separating means including grate elements arranged so that the fine grain portions of the bulky material pass through said grate elements into a respective one of said lateral passages, whereas the coarse grain portion of the bulky material is guided over said grate elements to pass into said central passage so as to form a pile having at least one central pile zone composed of the coarse grain portion of the bulky material, and two lateral pile zones composed of the fine grain portions of the bulky material.
