| 摘要 | In a hollow pyrometric incinerator grate structure are groups of axially spaced grate support means such as rings. Elongated grate bars are disposed on the support means circumferentially in rows about the interior of the hollow body. Each grate bar is engaged at its center with an intermediate support and the opposite ends of each grate bar bear freely on opposite axially spaced supports to enable biaxial stress relief. | ||||||
| 权利要求 | 1. In a pyrometric incinerator for disposing of combustible waste and the like, grate structure comprising: a. a rotatably mounted hollow body means having a feed opening, b. axially spaced apart grate support means mounted interiorly of said body means and extending generally circumferentially therein, one of said support means being axially intermediate other of said support means, c. elongated grate bar means disposed adjacent each other about the interior of said body means and extending generally axially to define a combustion chamber, d. said grate bar means having opposite end portions and an intermediate portion, the intermediate portion of said grate bar means having slot means for detachably engaging said grate bar means with said intermediate support means and said opposite end portions being supported in an axially unrestrained manner on said other support means respectively. 2. The invention set forth in claim 1 wherein: a. the opposite end portions of said grate means are planar and bear slidably on said other support means. 3. The invention set forth in claim 1 wherein: a. said grate support means comprise ring means which are axially displaced from each other and substantially encircle the interior of said hollow body means, b. said intermediate portion of the grate means being releasably engaged with said intermediate ring means and said opposite end portions bearing on said other of said ring means. 4. The invention set forth in claim 3 including: a. a plurality of circumferentially spaced apart ring-retaining means for each of said ring means, said retaining means being fastened to the interior of said body means. 5. The invention set forth in claim 1 wherein: a. said boDy means comprises a substantially conical hollow portion and a contiguous coaxial cylindrical hollow portion, some of said intermediate and said other support means being mounted in said conical portion and other of said intermediate and said other support means being mounted in said cylindrical portion. 6. The invention set forth in claim 1 wherein: a. said hollow body means comprises axially spaced apart flange means which each have an opening, b. a plurality of circumferentially adjacent strut means extending in a generally axial direction and having their opposite corresponding ends fastened to the flange means, respectively. 7. The invention set forth in claim 6 wherein: a. certain of said strut means are offset intermediate their ends in one circumferential direction and other of said adjacent strut means are offset intermediate their ends in an opposite circumferential direction and in contact with said certain strut means, whereby the strut means mutually support each other. 8. The invention set forth in claim 6 wherein: a. adjacent pairs of strut means diverge from their corresponding ends which are fastened to one flange means so as to contact next adjacent pairs of said strut means and then converge to their other corresponding ends which are fastened to the other of said flange means. 9. For use in an incinerator, a hollow grate support body comprising: a. a truncated conically shaped lattice means having an opening at one axial end and a relatively smaller opening at it other end, and b. grate supporting means mounted on the substantially conical interior of said lattice means. 10. The invention set forth in claim 9 including: a. a substantially cylindrical lattice means axially adjacent and fixed to said conically shaped lattice means. 11. The invention set forth in claim 9 wherein: a. said conically shaped lattice means comprises axially spaced apart flange means, and b. strut means distributed circumferentially about the exterior of said hollow body and fastened at opposed ends to respective flange means. 12. The invention set forth in claim 11 wherein: a. said strut means extend generally in an axial direction between said flange means, at least some of the strut means being offset and contacting adjacent strut means. 13. The invention set forth in claim 10 including: a. axially spaced apart flange means at opposite ends of said cylindrical lattice means, and b. strut means extending between and fastened to said last-named flange means defining said lattice means. 14. The invention set forth in claim 13 wherein: a. said strut means are arranged in triangular fashion circumferentially of said body to define said lattice means. |
