Description
Technical field
The present invention relates to central cooler, particularly a kind of circular cooler trolley comb plate unit and trolley grating plate.
Background technology
See also Fig. 1 and Fig. 4, Fig. 1 is the overall structure discharging sketch map of existing central cooler, and Fig. 4 is the partial top view of existing central cooler in the cooling zone.
Central cooler roughly is divided into high-temperature region, middle warm area, low-temperature space and non-cooling zone (high-temperature region, middle warm area and low-temperature space are referred to as the cooling zone).The side plate of each chassis 3 and inboard sideboard 4, outside breast board 7 and two adjacent chassis backbars 2 constitutes a central cooler cooling work unit.In the course of work, chassis 3 and chassis backbar 2 be in real time around the center uniform rotation of central cooler, and the mineral aggregate after sintering is accomplished is arranged in through the feed chute 5 of non-cooling zone loading station on the side plate of trolley grating plate 1 and chassis backbar 2 of chassis 3.That is to say that mineral aggregate to be cooled is arranged in by inboard breast board 4, outside breast board 7, the side plate of two adjacent chassis backbars 2 and the spatial accommodation that trolley grating plate 1 constitutes successively.Meanwhile, the rotation along with chassis 3 gets into three cooling zones successively: high-temperature region, middle warm area and low-temperature space return back to non-cooling zone unloading station, the completion discharge operation afterwards.At last, bogie wheels 32 rises along bend, and chassis 3 gets into the loading area charging after being reset to level again, circulation according to this.
At unloading station, chassis 3 is under the effect of himself and mineral aggregate deadweight, and bogie wheels 32 descends along the discharging guide rail, and chassis 3 does flip-flop movement around jointed shaft 31 between itself and the preposition chassis backbar 2, and trolley grating plate 1 is downward-sloping; Thereby make mineral aggregate in the aforementioned spatial accommodation along the side plate of chassis backbar 2 and trolley grating plate 1 landing to discharge chute 6.
Referring to Fig. 2 and Fig. 3, wherein, Fig. 2 is for having circular cooler trolley and the backbar partial circumferential cutaway view in the cooling zone now; Fig. 3 is an A portion enlarged drawing shown in Figure 2;
Existing trolley grating plate 1 comprises the child comb plate 11 that is arranged in parallel, and the plate of sub-comb plate 11 tilts towards the chassis rear side, with about about 20 degree of the angle of horizontal plane, less than the material angle of repose.When chassis carried out discharging, trolley grating plate 1 needed to the rear side upset, though the flip angle about 45 degree is arranged, the child comb plate 11 downward-sloping backs of this moment still can be less than the material angle of repose with the angle of horizontal plane.Will there be a small amount of buildup on the sub-comb plate 11, makes that trolley grating plate 1 discharging is incomplete.
Therefore, existing circular cooler trolley comb plate 1 receives the restriction of self structure, and after discharge operation was accomplished, sub-comb plate 11 places still had mineral aggregate residual, can't satisfy the requirement of complete unloading.Remain in the mineral aggregate on the comb plate; In the chassis reseting procedure, there is the possibility that scatters, when chassis will be returned to horizontal level, scatters the just not landing downwards again of mineral aggregate on the chassis lower floor flat board; Scatter at the mineral aggregate at the static seal device place on the chassis lower floor flat board and will be sandwiched between the seal of chassis lower floor flat board and static seal device; Damage static seal device, when serious, can cause the dull and stereotyped inelastic deformation of chassis lower floor.
In view of this, demand urgently being optimized design,, improve the cooling effect and the complete machine operating efficiency of central cooler to satisfy complete unloading to the structural relation of existing trolley grating plate 1.
