Description
Technical field
The utility model relates to rotary kiln, especially relates to a kind of rotary kiln kilneye cap iron.
Background technology
For extending the time between overhauls(TBO) of rotary kiln, the castable at rotary kiln kilneye place is fixed often through kilneye cap iron, comes off if castable is improper, directly will have influence on the life-span of kilneye cap iron, and then affect the life-span of kilneye cylindrical shell.The kilneye cap iron material that tradition uses is Cr25Ni20, dog material is Cr25Ni20, break iron and dog structure are shown in accompanying drawing 1: the section configuration of break iron is similar to Z-shaped, when being fixed on after on kilneye cylindrical shell, be respectively arranged with Y shape dog on break iron face inside cylindrical shell and on the break iron face of barrel port, by Y shape dog, castable be fixed on kilneye place.Due to Y shape dog and kilneye cylindrical shell to weld contact surface less, easily there is the phenomenon of dog not prison welding, and the structure of Y shape dog makes the thickness of castable limited, when kiln is produced, the castable of high temperature chamotte to kilneye place is washed away, and castable can be caused to wear and tear, come off, under causing kilneye cap iron to be directly exposed to high temperature chamotte, the break iron that 30mm is thick heat erosion extremely only can remain 10mm, directly jeopardizes the safety of kilneye cylindrical shell.
Summary of the invention
The purpose of this utility model be to provide a kind of rational in infrastructure, castable cast thickness can be improved and the rotary kiln kilneye cap iron of fixation.
For achieving the above object, the utility model can take following technical proposals:
Rotary kiln kilneye cap iron described in the utility model, comprise the connection backplate be fixedly mounted on kilneye cylindrical shell and the longitudinal backplate extended downward vertically from described connection backplate end, the bottom of described longitudinal backplate is provided with horizontal shelf, on the upside of described connection backplate, be respectively arranged with Y shape dog with the outside of longitudinal backplate; The corner angle junction of described connection backplate and longitudinal backplate is extended oblique support plate, and side and the top of described oblique support plate are respectively arranged with dog, and the dog being wherein positioned at oblique support plate top is v-shaped structure, and the dog being positioned at oblique support plate side is Y-shaped structure.
The outer end of described horizontal shelf is upturned formation rib, and under the end of described oblique support plate, folding forms rib.
The Y shape be arranged on described longitudinal backplate takes off staple height and the V-arrangement at oblique support plate top, and to take off staple height identical, and the Y shape be arranged on described connection backplate takes off staple height and the Y shape of oblique support plate side, and to take off staple height identical.
The bottom of described Y shape dog and V-arrangement dog is provided with welded plate, and described dog is all welded as a whole with described backplate, longitudinal backplate and the oblique support plate of being connected by the welded plate bottom it.
The utility model has the advantage of simple and reasonable for structure, by connecting the extended oblique support plate in corner angle junction of backplate and longitudinal backplate and arranging dog in the side of oblique support plate and top, the cast thickness of castable can be improved, the formation rib and the outer end of horizontal shelf is upturned, under the end of oblique support plate, folding forms the design of rib, large-arealy when both can prevent castable from chapping to come off, the wear-resisting cycle of break iron can also be strengthened, because when grog flows out in the kiln rotated, wear and tear the fastest position in the edges and corners, edge of castable, As time goes on, the castable of edges and corners is ground into arc, due to the increase of castable thickness, extend the time between overhauls(TBO) of kilneye, and after the castable of edges and corners is worn away, first the oblique support plate of break iron can be exposed, because surrounding has the parcel of castable, the wearing and tearing of break iron can be slowed down, effective prolongation its service life.
Accompanying drawing explanation
Fig. 1 is the structural representation of traditional break iron.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the using state figure that the utility model is arranged on kilneye.
Detailed description of the invention
As shown in Figure 2, rotary kiln kilneye cap iron described in the utility model, comprise the connection backplate 1 be fixedly mounted on kilneye cylindrical shell and the longitudinal backplate 2 extended downward vertically from connection backplate 1 end, the bottom of longitudinal backplate 2 is provided with horizontal shelf 3, on the upside of connection backplate 1, be respectively arranged with Y shape dog 4 with the outside of longitudinal backplate 2; For improving the thickness of castable, oblique support plate 5 is had with the corner angle junction of longitudinal backplate 2 is extended at connection backplate 1, side and the top of oblique support plate 5 are respectively arranged with dog, and the dog being wherein positioned at oblique support plate top is v-shaped structure, and the dog being positioned at oblique support plate side is Y-shaped structure.Cause large-area coming off when chapping for preventing castable, the outer end of horizontal shelf 3 is upturned and forms rib 6, and under the end of oblique support plate, folding forms rib 7.During general design, the Y shape be arranged on longitudinal backplate 2 takes off staple height and the V-arrangement at oblique support plate 5 top, and to take off staple height identical, is arranged on the Y shape connected on backplate 1 and takes off staple height and the Y shape of oblique support plate 5 side to take off staple height identical.For improving the firm welding degree of dog, be provided with foursquare welded plate 8(in the bottom of Y shape dog and V-arrangement dog and adopt heat-resisting steel sheet and plate), all dogs (comprising Y shape dog and V-arrangement dog) all by the welded plate 8 bottom it be connected backplate 1, longitudinal backplate 2 and oblique support plate 5 and be welded as a whole.
Break iron of the present utility model is arranged on the opening's edge portion of kiln cylinder body 10 by connecting bolt 9, as shown in Figure 3, dog material is Cr25Ni20, monolateral length optional selects 80mm, diameter is 16mm, and overall alignment becomes plum blossom-shaped, and the opening of V-arrangement dog can orthogonally stagger, for ensureing the welding quality of dog and kilneye material, stainless steel electrode can be used.After break iron is installed, then pour into a mould that intensity is high, anti-wear performance good, thermal shock resistance is strong, burn after the low and Special castable for kiln outlet 11 not easily cracked of Linear change rate.Due to the lengthening of dog and horizontal shelf, improve the cast thickness of castable 11, the outer end due to horizontal shelf 3 is upturned and forms rib 6, and under the end of oblique support plate, folding forms rib 7, large-arealy when preventing castable 11 to chap comes off.
During kiln work, grog 12 flows out from kilneye, gradually the castable 11 of kilneye edges and corners is worn into arc, because the thickness of castable 11 increases, extends the life cycle of kilneye; As time goes on, after the castable of edges and corners is worn away, first the V-arrangement dog on the oblique support plate 5 of break iron and Y shape dog can be exposed, oblique support plate 5 can be exposed again after using a period of time, because the periphery of dog and oblique support plate has castable to wrap up in, the service life of original four wheat harvesting periods can be extended to 18 wheat harvesting periods, what have even can reach more than 2 years, has exceeded the life-span of kiln clinkering zone brick body.
