Abstract

A conveyor belt comprising a series of belt links arranged in superimposed successive overlapping relation secured together by interlocking belt link fasteners and apertures, combined with heat protection barriers to protect the belt from contacting high temperature materials that are transported. The barriers interlock with the links of the belt forming a surface which contacts the high temperature materials.

Claims

1. A high temperature conveyor assembly for transporting hot materials on the side of the assembly comprising:

an interlocking link belt comprising a series of belt links arranged in superimposed successive overlapping relation, said belt having a thickness between its top and bottom sides corresponding to a thickness of at least two belt links, each of said belt links having;

a body portion with a lateral width, a longitudinal length, at least one aperture, and an integral fastener at a leading end of said body portion and longitudinally-aligned with said aperture, said fastener comprising;

a laterally constricted fastener neck portion; and

a fastening tab connected to said body portion through said neck portion;

said belt links of said series being secured together in overlapping relation to form a belt by the neck of said fastener extending from one of said sides of the belt through said aperture in a preceding belt link, said fastening tab engaging the other of said sides of said belt at the preceding belt link to secure the belt links together; and

a heat protection barrier connected to said belt links, positioned on the top side of the belt which confronts the hot material transported by the assembly so as to provide a barrier against the hot material contacting the top side of the belt.

2. An assembly according to claim 1 wherein said heat protection barrier comprises a series of barrier members each comprising a barrier body portion positioned on the top side of the belt and an integral connector comprising:

a laterally constricted connector neck portion; and

a connecting tab connected to said barrier body portion through said connector neck portion;

said barrier members being connected to said belt links by said connector neck extending through an aperture in at least one of said belt links, whereby said connecting tab is engaged on the other side of said belt.

3. An assembly according to claim 2 wherein each of said barrier members has at least one barrier aperture.

4. An assembly according to claim 3 wherein selected belt links have a barrier member associated with each of them, said barrier member being connected to said belt links by said barrier connector neck extending through a barrier aperture in the barrier member associated with the preceding selected belt link and a body aperture in at least one of said belt links.

5. An assembly according to claim 4 wherein said barrier member aperture is longitudinally-aligned with said connector.

6. An assembly according to claim 5 wherein said barrier member body has a lateral width at least as wide as the width of said belt links.

7. An assembly according to claim 3 wherein said barrier member has both a leading aperture and a trailing aperture longitudinally-aligned with said connector, said barrier member being connected to said series of belt links by said belt link fastener extending through said barrier leading aperture, and said barrier connector extending through both said barrier trailing aperture and said aperture in at least one belt link body portion.

8. An assembly according to claim 1 wherein each of said belt links of the belt has at least two apertures, one of said two apertures being longitudinally spaced from the other of said apertures, said one aperture being a leading aperture and said other aperture being a trailing aperture, said plurality of belt links being secured together in overlapping relation to form a belt by said link fasteners extending from one side of the belt through a leading aperture in the preceding belt link and a trailing aperture in a next preceding belt link, and said fastening tab engaging said next succeeding belt link on the other side of the belt.

9. An assembly according to claim 3 wherein each of said belt links of the belt has at least two apertures, one of said two apertures being longitudinally spaced from the other of said apertures, said one aperture being a leading aperture and said other aperture being a trailing aperture, said barrier members being connected to said series of belt links by said belt link fasteners extending through an aperture in an adjacent belt link and an aperture in an adjacent barrier member, and said barrier member connectors extending through an aperture in the preceding belt link.

10. An assembly according to claim 1 wherein said heat protection barrier comprises a series of barrier members having a portion positioned to support the hot material transported by said belt, said barrier member portion comprising a heat resistant polymer.

11. An assembly according to claim 10 wherein said heat resistant polymer is PTFE.

12. An assembly according to claim 1 wherein said heat protection barrier comprises a series of barrier members having a portion positioned to support the hot material transported by said belt, said barrier members having a top surface to which a heat resistant material is attached.

13. An assembly according to claim 1 wherein said fastening tab of each belt link engages the top side of the belt, and said heat protection barrier comprises a series of barrier members, each member having a socket engaging one of said fastening tabs to secure said barrier members to said link fastening tabs.

14. A high temperature conveyor assembly for transporting hot materials on a top side of the assembly comprising:

an interlocking-link belt comprising a series of belt links arranged in superimposed successive overlapping relation, said belt having a thickness between its top and bottom sides corresponding to a thickness of at least two belt links, each of said belt links having;

a body portion having a lateral width, a longitudinal length, an upper and lower surface, a leading aperture, a trailing aperture longitudinally spaced from said leading aperture and an integral fastener at a leading end of said body, longitudinally-aligned with said leading aperture, said fastener comprising;

a laterally constricted fastener neck portion; and

a fastening tab connected to said body portion through said neck portion;

a heat protection barrier connected to said belt links positioned on the top side of the assembly which confronts the hot material transported by the assembly so as to provide a barrier against hot material contacting the top side of the belt, said barrier comprising a series of barrier members comprising;

a barrier member body portion having a lateral width at least as wide as a width of said belt links, and having a barrier aperture, said barrier member body comprising a layer of a heat resistant polymer positioned on the top side of the belt; and

an integral connector longitudinally-aligned with said barrier aperture, comprising;

a laterally constricted connector neck portion; and

a connecting tab connected to said barrier body portion through said connector neck portion;

said plurality of belt links being secured together in overlapping relation to form a belt by said fasteners extending from one side of the belt through a leading aperture in a preceding belt link and a trailing aperture in a next preceding belt link, and said fastening tab engaging said next preceding belt link on the other side of the belt;

wherein selected belt links have a barrier member associated with them, said heat protection barrier being connected to said selected belt links by said barrier connector neck extending through a barrier aperture in the barrier member associated with the preceding selected belt link and an aperture in at least one belt link body portion, whereby said connecting tab is engaged on the other side of said belt links.

15. An assembly according to claim 14 wherein said barrier member has both a leading aperture and a trailing aperture longitudinally-aligned with said connecting means, said barrier members being connected to said series of belt links by said belt link fastener extending through said barrier leading aperture, and said barrier connector extending through both said barrier trailing aperture and said aperture in at least one belt link body portion.
