The specific embodiment

The reciprocating type waste incineration fire grate of interlock of the present utility model is the reciprocating fire grate that has step therein, is in tilted layout, on whole fire grate length direction, be divided into preheating and drying section, burning zone and burning segment, between preheating and drying section fire grate and burning zone fire grate, generally be provided with a step therein, this fire grate has certain included angle in the whole grate surface layout that tilts with horizontal plane.This fire grate is the pushing direction of the fire grate forwards fire grate identical with the rubbish travel direction.The grate surface of this fire grate is formed by connecting by some fire grate segments, and the adjacent fire grate segment in front and back is overlapping up and down, and the adjacent fire grate segment in the left and right sides then is cascaded by a series of pull bar and becomes one group, so that pace of movement is unified.The fire grate component is the fixed grate group and moves back and forth the fire grate group that front and back repeat to be provided with at interval.Fig. 1 has only represented the frame mode that one of them is local, and Fig. 2, Fig. 3 and Fig. 4 then are several running statuses of having represented these partial structurtes, resolve as follows below respectively:

As shown in Figure 1, this reciprocating type domestic waste incineration package that links is drawn together: fixed grate group 2, with and front and back subsidiary movably two groups move back and forth fire grates: first group of motion fire grate 1 and second group of motion fire grate 3, fixed grate group 2 is installed on the fixing furnace grate support, first group of motion fire grate 1 and second group of motion fire grate 3 are installed in respectively then on the drive link 5 of the drive link 4 of first group of motion fire grate and second group of motion fire grate that (rolling that all is provided with the band inclined plane below the drive link 5 of the drive link 4 of first group of motion fire grate and second group of motion fire grate is supported, do not show among Fig. 1), and then the drive link of passing through separately links to each other with drive plate 6, thereby constitute complete " toggle " of a cover, 7 on hydraulic-driven bar is by pushing away, draw drive plate 6 to realize control to the motion fire grate, first group of motion fire grate 1 and second group of motion fire grate 3 move simultaneously and the direction of motion opposite, its movement locus is coordinated by drive plate 6.

As shown in Figure 1, when hydraulic-driven bar 7 travels forward, drive plate 6 will move counterclockwise, the drive link 4 of first group of motion fire grate will move downward backward this moment, thereby driving first group of motion fire grate 1 moves backward, and the drive link 5 of second group of motion fire grate will move upward forward, thereby driving second group of motion fire grate 3 moves forward, reach capacity (original state as shown in Figure 2) behind the position, hydraulic-driven bar 7 is motion backward again, drive plate 6 will move clockwise, the drive link 4 of first group of motion fire grate will move upward forward this moment, thereby driving first group of motion fire grate 1 moves forward, and the drive link 5 of second group of motion fire grate will move downward backward, moves backward thereby drive second group of motion fire grate 3, behind the position that reaches capacity (end-state as shown in Figure 4), hydraulic-driven bar 7 travels forward again, thereby finishes a period of motion.

From Fig. 2, Fig. 3 and Fig. 4 as can be seen, when hydraulic-driven bar 7 from after travel forward arrive extreme position after the motion position that reaches capacity backward in the past again, whole fire grate will move to " intermediateness " (as shown in Figure 3) and pass through " intermediateness " (as shown in Figure 3) again after reaching " end-state " (as shown in Figure 4) and turn back to " original state " (as shown in Figure 2) from " original state " (as shown in Figure 2), finish the continuous operation that goes round and begins again.

Because fixed grate group 2 subsidiary two groups movably fire grate (first group of motion fire grate 1 and second group of motion fire grate 3) is driven by a cover crank linkage, one group another is organized in motion in the opposite direction when upwards moving forward, and reach the limit of the position simultaneously, and then to moving in the other direction.When fire grate reaches " end-state " and " original state ", to between two adjacent motion fire grates, form a maximum drop, rubbish generation on the fire grate is once stirred, the continuous periodic motion of fire grate from " original state " to " end-state ", rubbish on the fire grate will roll forward in periodically stirring, thereby finish combustion process completely.
