Grate structure for incineration plants

Claim 2

A grate installation for incinerator plants including, in combination, a reciprocable support plate structure having forward and rear ends and a receiving area proximate the latter for receiving materials dropped from above thereon; structural means for supporting said support plate structure for back-andforth movements thereover; fixed upright reaction baffle means transversely disposed above said support plate structure proximate and rearwardly of the receiving area thereof; means for translationally reciprocating said support plate structure, said baffle means comprising the sole means, with the dropping of succeeding materials, for advancing prior-dropped materials forwardly along said support plate structure; and bed structure operably disposed forwardly of and overlapping underneath the forward end of said support plate structure, said support plate structure having transverse kicker plate means at its forward end for advancing forwardly materials dropping over said forward end of said support plate structure onto said bed structure.

Claim 3

The grate installation of claim 1 wherein said reciprocable support plate structure comprises a series of longitudinally parallel plates and a series of longitudinally intermediate members supporting said plates, said intermediate members operably and translationally bearing upon said structural means.

Claim 4

The grate installation of claim 1 wherein said structural means includes plural solely planar, raised roller bearing means for engaging and thereby supporting for translational movement said support plate structure.

Claim 5

The grate installation of claim 1 wherein said support plate structure includes wear plate means affixed to and disposed on the underneath side thereof, said structural means for supporting said support plate structure including solely planar upstanding bearing means for engaging said wear plate means.

Claim 6

The grate installation of claim 1 wherein said translationally reciprocating means comprises rack means keyed to said support plate structure for movement therewith, shaft means including pinion means engaging said rack means, and means for revolving said shaft.

Claim 7

Structure according to claim 5 wherein said means for revolving said shaft comprises a reversible motor, and means for initiating and limiting the revolvement travel of said motor at its output in both directions.

Claim 8

The grate installation of claim 1 wherein said reciprocable support plate structure includes plurar longitudinal intermediate structures, said structural means including means for bearingly supporting said intermediate structures, and longitudinal plate means longitudinally spanning said intermediate structures.

Claim 9

A grate installation for incinerator plants including, in combinatioN, a reciprocable support plate structure having forward and rear ends and a receiving area proximate the latter for receiving materials; structural means for supporting said support plate structure for back-and-forth movements thereover; reaction baffle means transversely disposed above said support plate structure proximate and rearwardly of the receiving area thereof; means for translationally reciprocating said support plate structure; and bed structure operably disposed forwardly of and overlapping underneath the forward end of said support plate structure, said support plate structure having transverse kicker plate means at its forward end for advancing forwardly materials dropping over said forward end of said support plate structure onto said bed structure, said structural means including plural, raised roller bearing means for engaging and thereby supporting for translational movement said support plate structure, and wherein said engaging and supporting means are adjustable in height, whereby to adjust the planar disposition of said support plate structure.

Claim 10

A grate installation for incinerator plants including, in combinatioN, a reciprocable support plate structure having forward and rear ends and a receiving area proximate the latter for receiving materials; structural means for supporting said support plate structure for back-and-forth movements thereover; reaction baffle means transversely disposed above said support plate structure proximate and rearwardly of the receiving area thereof; means for translationally reciprocating said support plate structure; and bed structure operably disposed forwardly of and overlapping underneath the forward end of said support plate structure, said support plate structure having transverse kicker plate means at its forward end for advancing forwardly materials dropping over said forward end of said support plate structure onto said bed structure, said structural means including plural, raised roller bearing means for engaging and thereby supporting for translational movement said support plate structure, and wherein said engaging and supporting means are adjustable in height, whereby to adjust the planar disposition of said support plate structure.

Claim 11

A grate installation for incinerator plants including, in combination, translational, reciprocating means for receiving materials dropping thereon from a separate source disposed thereabove and having a forward end; upright fixed baffle means positioned above said reciprocating means for impeding rearward travel of said materials and for defining a baffle boundary of materials to be subsequently dropped upon said reciprocating means as the latter is successively advanced forwardly in its operating cycle, said reciprocating means including a forward kicker plate at said forward end, bed structure operably disposed beneath the forward end of said reciprocating means and structurally configured such that said kicker plate operates to successively advance materials, advancing over the forward end of said support structure, onto said bed in a series of successive pushing steps, and means for reciprocating said support structure along a direction between said baffle means and said kicker plate.

Claim 12

A grate installation for incinerator plants including, in combination, translational, reciprocating means for receiving materials dropping thereon from a separate source disposed thereabove and having a forward end; upright fixed baffle means positioned above said reciprocating means for impeding rearward travel of said materials and for defining a baffle boundary of materials to be subsequently dropped upon said reciprocating means as the latter is successively advanced forwardly in its operating cycle, said reciprocating means including a forward kicker plate at said forward end, bed structure operably disposed beneath the forward end of said reciprocating means and structurally configured such that said kicker plate operates to successively advance materials, advancing over the forward end of said support structure, onto said bed in a series of successive pushing steps, and means for reciprocating said support structure along a direction between said baffle means and said kicker plate.
