Abstract
The utility model relates to an improved turnover fire grate, which comprises two or more fire grate sheets. A rotating shaft which can drive the fire grate sheet to turn is fixedly installed on each fire grate sheet; each rotating shaft is connected with a pull rod through a totating arm which is fixedly connected with the rotating shaft; the rotating shafts are parallel to each other and are perpendicular to the pull rod; an operating rod is installed on the outer end of the pull rod. The utility model is characterized in that the working surface of the fire grate sheet is convex upwards and is an arc-shaped surface which is parallel to the rotating shaft, and the improved turnover fire grate has double functions of mechanical dredging for discharging slag.
Description
The utility model relates to a kind of improved dump grate, belongs to the combustion apparatus of coal-burning boiler.
Existing dump grate is to be installed with the rotating shaft that drives its upset on two or more fire grate segments compositions, each fire grate segment, rotating shaft is connected with pull bar by fixedly connected with it turning arm, and each rotating shaft is parallel to each other, when the outer end of pull bar is equipped with the action bars use, by axle bed rotating shaft is installed on the burner hearth bottom body of heater, action bars is installed on the body of heater shell by fixed arm.By the action bars operation fire grate segment is overturn synchronously, when getting back to horizontal level, each fire grate segment is spliced into fire grate, and in the prior art, the working face of fire grate segment is the plane.Its weak point is, because the grate surface of planar structure between fire grate segment and the slag blanket on it relative displacement does not take place when it overturns, be with the whole upset of slag blanket, slag blanket ruptures between the adjacent fire grate segment, and produces bigger dislocation, cause burning zone and coal seam above the slag blanket to be damaged simultaneously, not only influence burning time, also increase the loss of uncombusted coal, cause waste, the dump grate of this structure, function singleness can only deslagging, can not dredge.
The purpose of this utility model is to provide a kind of can reduce coal leakage quantity, and has the dump grate of slagging and mediation dual-use function.
Technical solution of the present utility model is: the dump grate of being made up of two or more fire grate segment, fixed installation drives the rotating shaft of its upset on each fire grate segment, each rotating shaft is connected with pull bar by fixedly connected with it turning arm, each rotating shaft is parallel to each other and is vertical with pull bar, the outer end of pull bar is equipped with action bars, it is characterized in that, the working face of fire grate segment be raise up and with the arcwall face of shaft parallel.
The utility model has the advantages that camber dump grate when upset, the effect of the slag layer during curved working face on it is similar to cam.Produce relative displacement along the tangent plane direction on the one hand and between the slag blanket, give the slag blanket active force on the other hand along the vertical aspect, jack-up makes progress, therefore making fire grate segment overturn, reset by action bars moves back and forth, can make fire grate segment between slag layer, constantly produce friction, and slag blanket is fluctuateed up and down, slag blanket is played broken and loosening effect, reach machinery mediation purpose, have slagging and mediation dual-use function.During slagging, obviously fracture and inconsistent phenomenon do not take place in slag blanket, do not destroy burning zone and coal seam on it, reduce coal leakage quantity, can guarantee burning time, and slagging and mediation are all very laborsaving.
Following accompanying drawing has been described embodiment of the present utility model.
Fig. 1 is a structural representation of the present utility model
Fig. 2 is an A-A cutaway view among Fig. 1
Fig. 3 is a B-B cutaway view among Fig. 1
Below in conjunction with accompanying drawing the utility model is described in detail.The difference of the utility model and existing dump grate only is that the working face of fire grate segment raises up, and curved working face has promptly made existing plane working face into curved working face, and other structures and existing dump grate are identical, as shown in the figure.2 is rotating shafts among the figure, and it is fixedlyed connected with fire grate segment 10 by stiffener 1.One end of turning arm 3 is fixedlyed connected with rotating shaft 2, and its other end is hinged by bolt 5 and pull bar 6, and the outer end of pull bar 6 is equipped with action bars 8.Present embodiment is made up of two fire grate segments 10, and two rotating shafts are parallel to each other and are vertical with pull bar 6.4 is the opening axle bed among the figure, and 7 is fixed arm.Fire grate segment 10 of the present utility model is rectangle, and two long limit is and the straight flange of shaft parallel, and two minor faces are arc limits vertical with rotating shaft, working face be raise up and with the arcwall face of shaft parallel.Its concrete structure is, constitute rectangle framework with the long limit of shaft parallel with two arc minor faces vertical by two with rotating shaft, fixed installation and the parallel straight fire bars in long limit between two arc minor face comprise that then the straight fire bars of two straight flanges constitutes the curved working face that raises up.In the present embodiment, fire bars 11 on the fire grate segment 10 is an arc fire bars and vertical with rotating shaft, promptly by two with the long limit of shaft parallel and rectangle framework that two arc minor faces vertical with rotating shaft constitute in, the fixed installation arc fire bars 11 parallel with minor face between its two long limit comprises that then the arc fire bars 11 of two arc minor faces constitutes the curved working face that raises up.As another embodiment, fire grate segment 10 be a kind of have raise up and with the curved working face of shaft parallel be the cast iron sheet that is rectangle, on its face, be processed with passage.Above-described various fire grate segment all adopts the casting method one-shot forming to form.
Claims (2)
1. dump grate, the fire grate segment (10) that comprises two or more, each fire grate segment (10) is gone up the rotating shaft (2) that fixed installation drives its upset, each rotating shaft is connected with pull bar (6) by fixedly connected with it turning arm (3), each rotating shaft is parallel to each other and is vertical with pull bar, the outer end of pull bar is equipped with action bars (8), the working face that it is characterized in that fire grate segment (10) be raise up and with the parallel arcwall face of rotating shaft (2).
2. dump grate according to claim 1 is characterized in that the fire bars (11) on the described fire grate segment (10) is the arc fire bars, and vertical with rotating shaft.
