Abstract
The reciprocal coal leak preventing fire grate of the broken burnt type of angled step, formed by polylith moving grate and polylith fixed grate spaced-apart relation, moving grate main body and fixed grate main body have angled step formula structure, fixed grate body end sets coal leak preventing to protect wing, moving grate main body sets sliding block and chute corresponding to the coal leak preventing shield wing of fixed grate, the sliding block of moving grate is overlapped under the coal leak preventing of adjacent fixed grate shield wing, and moving grate main body both sides are symmetrical arranged dividing plate.It is constant that the utility model fire grate shakes ventilation gap, changing ventilation gap when conventional fire grate shakes and increasing causes to leak coal, so as to prevent to waste, the step inclined position of moving grate breaks Jiao as ploughing sample when fire grate shakes, fire grate is set to keep good ventilation, inclined fire grate is changed due to the problem of boiler power declines caused by the thickness compacting burning zone rear venting effect difference of coal seam in addition.
Description
Technical field
The utility model is related to combustion apparatus auxiliary technical field, and in particular to a kind of reciprocal leakproof of the broken burnt type of angled step
Coal stove is arranged.
Background technology
The fire grate that coal-burning boiler is used include two kinds of traveling-grate stoker and reciprocal grate, traveling-grate stoker to coal quantity requirement compared with
Height, traveling-grate stoker is not applied for colm；Reciprocal grate is to be arranged side by side to form by multiple fire grate segments and coal-pushing plate, fire grate segment
Larger gap can be produced in reciprocatory movement with coal-pushing plate, causes fire-gate leakage coal serious, causes coal-fired waste.
Utility model content
The utility model provides a kind of reciprocal coal leak preventing fire grate of the broken burnt type of angled step, to solve prior art presence
The problem of fire-gate leakage coal causes coal-fired waste.
The utility model solves the technical scheme that its technical problem used：
A kind of reciprocal coal leak preventing fire grate of the broken burnt type of angled step, is spaced by polylith moving grate and polylith fixed grate
Arrangement is formed, and moving grate main body and fixed grate main body have angled step formula structure, and fixed grate body end sets anti-
Coal shield wing is leaked, moving grate main body sets sliding block and chute, the sliding block of moving grate corresponding to the coal leak preventing shield wing of fixed grate
It is overlapped under the coal leak preventing of adjacent fixed grate shield wing, moving grate main body both sides are symmetrical arranged dividing plate.
The end difference of the utility model coal leak preventing boiler grate be deliver coal Po Jiao areas be also boiler primary zone, fire grate it is flat
Straight area is the burning-out zone of boiler, and rocking furnace is worked as in the ladder position of moving grate and fixed grate on same inclined-plane during normal work
Moving grate integral forward lead during row, now moving grate ladder position and the ladder position of stationary furnace be not or not same inclined-plane, fire grate
End difference promote fuel reach and so on to shake to deliver coal and synchronously complete so that pushing away slag, broken Jiao, the leakproof of fixed grate end
Coal protects wing in the coal storage area of boiler, and the end of moving grate coal storage is all the time in fixed grate in moving grate reciprocatory movement
Protect under wing, occur the constant anti-leak-stopping coal of ventilation gap of fire grate during stove.
The utility model fire grate feature：1 fire grate shake ventilation gap is constant, changes ventilation gap when conventional fire grate shakes
Increasing causes to leak coal, so as to prevent to waste.The step inclined position of moving grate breaks Jiao as ploughing sample when 2 fire grates shake,
Fire grate is set to keep good ventilation, solving conventional fire grate coking rear venting effect and being deteriorated causes asking for boiler power decline
Topic.3 inclined fire grates, which increase mobility coal-fired in stove and loosened burning zone and improve ventilation effect, increases boiler power,
Solve due to the problem of boiler power declines caused by the thickness compacting burning zone rear venting effect difference of coal seam.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of the utility model fixed grate；
Fig. 3 is the schematic top plan view of the utility model fixed grate；
Fig. 4 is the structural representation of the utility model moving grate；
Fig. 5 is the schematic top plan view of the utility model moving grate.
1 fixed grate, 2 moving grates, 11 coal leak preventings shield wing, 21 sliding blocks, 22 chutes, 23 dividing plates in figure.
Embodiment
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4 and Fig. 5, a kind of reciprocal coal leak preventing fire grate of the broken burnt type of angled step is lived by polylith
Dynamic fire grate 3 and the spaced-apart relation of polylith fixed grate 1 are formed, and the main body of moving grate 2 and the main body of fixed grate 1 have inclination rank
Ladder type structure, the body end of fixed grate 1 sets coal leak preventing to protect wing 11, and the main body of moving grate 2 is corresponding to the anti-of fixed grate 1
Leak coal shield wing 11 and sliding block 21 and chute 22 are set, the sliding block 21 of moving grate 2 is overlapped on the coal leak preventing shield wing of adjacent fixed grate 1
Under 11, the main body both sides of moving grate 2 are symmetrical arranged dividing plate 23.
The end difference of the utility model coal leak preventing boiler grate be deliver coal Po Jiao areas be also boiler primary zone, fire grate it is flat
Straight area is the burning-out zone of boiler, and rocking furnace is worked as in the ladder position of moving grate and fixed grate on same inclined-plane during normal work
Moving grate integral forward lead during row, now moving grate ladder position and the ladder position of stationary furnace be not or not same inclined-plane, fire grate
End difference promote fuel reach and so on to shake to deliver coal and synchronously complete so that pushing away slag, broken Jiao, the leakproof of fixed grate end
Coal protects wing in the coal storage area of boiler, and the end of moving grate coal storage is all the time in fixed grate in moving grate reciprocatory movement
Protect under wing, occur the constant anti-leak-stopping coal of ventilation gap of fire grate during stove.
Claims (1)
