Abstract
The utility model discloses a double-conical-surface fixing structure for matching a rolling ring seat and a rolling ring of a calcining furnace, belonging to the technical field of the manufacture of the calcining furnace and comprising the rolling ring, the rolling ring seat and a cylinder body, wherein the rolling ring is provided with double conical surfaces; wedge-shaped pad iron is arranged between the rolling ring and the rolling ring seat and is matched with the conical surfaces of the rolling ring; a guide plate is arranged between the wedge-shaped pad iron; the outer ends of the wedge-shaped pad iron are provided with fixed rings and pressing bolts and nuts matched with the fixed rings; the rolling ring is sheathed on the rolling ring seat; a plurality of wedge-shaped pad iron guided and positioned by the guide plates are filled into a gap of the rolling ring seat and the rolling ring; the pressing bolts rotatably connected on the fixed rings tightly jack the wedge-shaped pad iron inwards along with the double conical surfaces of the rolling ring so as to realize the fixation of the rolling ring seat and the rolling ring of the calcining furnace. The two surfaces of the double-concial-surface rolling ring has uniform stressing, thus improving the stressing of the pressing bolts; the matched surface of the rolling ring seat and the rolling ring does not need to be matched and processed, thus reducing processing difficulty; only the wedge-shaped pad iron is needed for adjustment, thus being convenient to be assembled; and the preparation of the spare parts is easy, thus being more convenient to replace the rolling ring on a using field.
Description
Affiliated technical field
The utility model relates to a kind of huge revolving equipment, especially calcining furnace, belongs to calcining furnace manufacturing technology field.
Background technology
Calcining furnace belongs to a kind of huge revolving equipment, its essential structure is: rotating horizontal cylindrical furnace body is supported by two pairs of support rollers by two rolling rings, under the effect of motor and transmission mechanism, do gyration, the heating tubulation is housed in the stove, material enters in the stove from burner, the indirect of thermal medium is decomposed in heating tube, and dried product is exported from the stove tail.Because the weight of material passes to four support rollers by front and back two rolling rings in whole calcining furnace body (more than common hundred tons) and the stove, so the bond strength of cylindrical furnace and rolling ring is most important.Existing structure adopts single cone match (as shown in Figure 3) more, uses bolt 1,2 ways of connecting again after promptly having the rolling ring 7 of inner conical surface and the rolling ring seat 6 with male cone (strobilus masculinus) on being welded in cylindrical shell cooperating.The problem that exists is, rolling ring and rolling ring seat are cone match, and in order to guarantee to cooperate exactly, rolling ring and rolling ring seat generally all adopt joins work, and difficulty of processing is big, and measurement is difficult; Owing to be the equipment of being heated, distortion such as circle can appear losing in the rolling ring seat after the long-time running, and rolling ring is changed the back and is difficult to work good with the rolling ring seat; Owing to be cone match, normal pressure makes rolling ring that tendency away from the rolling ring seat be arranged at the component of the conical surface, and fastening bolt is subjected to very big shearing force, causes loosening, fracture easily, and a whole set of the connection lost efficacy.
The utility model content
Combine the problem that poor reliability, processing are adjusted difficulty with rolling ring at existing calcine furnace rolling ring seat, the utility model provide a kind of stressed evenly, processing easily, install and change convenient, the fixed structure that cooperates with rolling ring in conjunction with reliable rolling ring seat.
The technical scheme that its technical problem that solves the utility model adopts is: the bipyramid face fixed structure that the calcine furnace rolling ring seat cooperates with rolling ring, comprise rolling ring, rolling ring seat and cylindrical shell, rolling ring is provided with the bipyramid face, be provided with the wedge shape parallels between rolling ring and the rolling ring seat, the wedge shape parallels matches with the conical surface of rolling ring, be provided with guide plate between the wedge shape parallels, hold-down bolt and nut that wedge shape parallels outer end is provided with retainer plate and cooperates with it.
Rolling ring seat with cylinder mating surface is welded on the body of heater cylindrical, the rolling ring of interior circle bipyramid face is sleeved on the rolling ring seat, some wedge shape parallels by the guide plate guide-localization are clogged in the gap of rolling ring seat and rolling ring by both direction, be rotatably connected on the hold-down bolt on the retainer plate, the wedge shape parallels is held out against towards interior along the rolling ring bipyramid, after finishing, adjusting hold-down bolt is locked with nut, rely on the huge frictional force that produces between wedge shape parallels and rolling ring seat and rolling ring mating surface, realize the fixing of calcine furnace rolling ring seat and rolling ring.
The beneficial effects of the utility model are, and are rational in infrastructure, and bipyramid face rolling ring two sides is stressed evenly, and it is stressed to improve hold-down bolt; The rolling ring seat must not cooperate processing with the rolling ring mating surface, has reduced difficulty of processing; Only need to adjust with the wedge shape parallels, convenient for assembly; Spare part is prepared easily, uses on-the-spot replacing rolling ring more convenient.
Description of drawings
Fig. 1 is the utility model general structure schematic diagram;
Fig. 2 is the A-A cutaway view of Fig. 1;
Rolling ring and associated components structural representation in the existing incinerator of Fig. 3.
Parts and numbering among the figure:
The 1-hold-down bolt, the 2-nut, the 3-retainer plate, 4-wedge shape parallels,
The 5-guide plate, 6-rolling ring seat, 7-rolling ring, 8-calcining furnace cylindrical shell.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As Fig. 1,2, the bipyramid face fixed structure that the calcine furnace rolling ring seat cooperates with rolling ring, comprise rolling ring 7, rolling ring seat 6 and cylindrical shell 8, rolling ring 7 is provided with the bipyramid face, be provided with wedge shape parallels 4 between rolling ring 7 and the rolling ring seat 6, wedge shape parallels 4 matches with the conical surface of rolling ring 7, is provided with guide plate 5 between the wedge shape parallels 4, hold-down bolt 1 and nut 2 that wedge shape parallels 4 outer ends are provided with retainer plate 3 and cooperate with it.
The rolling ring seat 6 on the cylindrical face of cylinder is welded on the cylindrical of calcining furnace cylindrical shell 8, rolling ring 7 suits with bipyramid face are on it, some guide plate 5 usefulness bolts 2 evenly are fixed on calcining furnace cylindrical shell 1 cylindrical, the wedge shape parallels 4 identical with bipyramid face gradient filled between rolling ring 7 and the rolling ring seat 6 by the both direction plug along guide plate 5, retainer plate 3 is fixed on the rolling ring seat 6, rotate hold-down bolt 1 and adjust wedge shape parallels 4 positions, proofread and correct the circular runout and the end face run-out of rolling ring 7 cylindricals, reach locking nut 2 after the requirement, utilize the huge frictional force that produces between wedge shape parallels 4 and rolling ring seat 6 and rolling ring 7 mating surfaces, rolling ring 7 is fixed on the rolling ring seat 6 accurately.
