Abstract
The present invention relates to a flexible shaft structural operation chain grate bed of a chain grate, which is suitable for a chain grate-rotary kiln system and other operation chain devices used for a heat transmission wide chain grate. The present invention has the structure that lining sleeves are added between chain links and long shafts, wherein the chain links are connected into strings by the lining sleeves to bear the operation pulling force, and a cross connecting shaft adopts a long and thin flexible shaft structure to control pitch deflection and self-compensation synchromesh deflection. Therefore, a plurality of chains on the whole grate bed can be simultaneously stressed, the grate bed trends to run stably, and the service life of the present invention can be prolonged.
Description
Technical field
The invention belongs to field of metallurgical equipment, relate to drying grate operation chain grate bed structure and connecting mode, be applicable to grate kiln system and other wide comb drying grate chain operation device that is used to conduct heat.
Background technology
Grate kiln is produced the pelletizing system, green-ball go into to move the chain bed surface by tail to head, be discharged into rotary kiln after drying, dehydration, the preheating, further roasting becomes finished product.Change backhaul over to tail after the discharging of operation chain warp great wheel, go round and begin again, continuously running.Therebetween, institute by normal temperature to 1000 ℃-1100 ℃ of high temperature, replaces cold and hot variation through gas phase temperature, and operating mode is very abominable.Ten meters of the comb bed long numbers of general operation chain, wide 3-5 rice, the chain that several are conspired to create by chain link 4 presss from both sides several piece therebetween and is contained in grate plate 2 on the distance sink tube 1, and backgauge side plate 5 is equipped with at two ends, and axle sleeve 6 conspires to create one with a major axis 3, and axle 3 terminations are fixed with baffle ring 7 welding.Carry pulling force to be born by chain link 4 and axle 3 chains that are linked to be during operation, grate plate 2 is only born the load of material.Chain link 4 is linked to be string, and 3 on the axle that grate plate 2 fuses holds to be sheared and bending force.Corresponding comb bed laterally has several chains, and driving on the great wheel then has identical several sprocket wheel, thus require several sprocket wheels to want synchronously and chain link 4 engagements, otherwise chain link 4 dislocation, the chain unbalance stress causes axle 3 bendings, even fractures.Several chains are stressed equally often, can't bear the heavy load, the accident that causes chain link to break.
In addition at high temperature, the material creep stress becomes several times to descend, and a drying grate has thousands of chain links, grate plate, and hundreds of major axis are as long as there is the parking that all may cause the accident of ging wrong during operation.How guaranteeing a plurality of sprocket wheels and corresponding chain synchro-meshing on the drying grate driving shaft, is to guarantee that drying grate operation chain runs well, drying grate key of producing steady in a long-term.
Summary of the invention
The present invention proposes at the problems referred to above, promptly by the transformation of the bed assembly structure of combing, improves the stress of chain link and major axis, makes many chains on the bed of combing simultaneously stressed, to reduce stress, increases the service life.
The technical solution adopted for the present invention to solve the technical problems is: drying grate flexible axle comb bed comprises chain link, chain link lining, grate plate, side plate, major axis, thimble, back-up ring, snap ring, between chain link and major axis, be provided with a lining, with lining chain link is linked to be string, described lining and chain link adopt little gap movingly, with between centers be big gap movingly, inner shield ring is imbedded the grate plate side and is prevented thimble and lining play, major axis adopts elongated flexible axle construction, and axle head adopts snap ring to fix.
Be provided with a lining between chain link and major axis, with lining chain link be linked to be string, described lining and chain link adopt movingly closely spaced, and chain pitch is controlled, and inner shield ring is imbedded the grate plate side and prevented thimble and lining play.The shearing force commentaries on classics that former major axis bore is born by lining, because the only corresponding one pair of chain link of lining, assembling is guaranteed.Major axis just laterally fuses chain link, grate plate, only bear very little material load and bending stress, can be made into the elongated flexible axis of no-feathering, the cover endoporus stays big gap with axle, with compensated chain voluntarily successively apart from and mesh nonsynchronous deviation, make many chains on the same major axis all be in stress, load is shared, and stress reduces.In addition, the termination of axle changes snap ring into and fixes, and promptly is close to the baffle ring place at shaft end and opens two symmetrical notches, and n shape snap ring is inserted along groove, and bayonet socket bended encase spindle nose, conveniently assemble and disassemble, it is removing damaged to exempt welding.
The invention has the beneficial effects as follows that chain pitch is controlled, engagement is guaranteed that the chain on the bed of combing all is in stress, and load is shared, and stress reduces, and the life-span is prolonged.The change of assembling form is also easy to installation and maintenance.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a comb bed plane of the present invention;
Fig. 2 is the A-A profile of Fig. 1;
Fig. 3 is the plane of the former general bed of combing;
Fig. 4 is the A-A profile of Fig. 3.
Among the figure, 1. thimble, 2. grate plate, 3. major axis, 4. chain link, 5. side plate, 6. axle sleeve, 7. baffle ring, 8. snap ring, 9. lining, 10. inner shield ring.
The specific embodiment
In Fig. 1, adding lining 9 usefulness elongated flexible major axis 3 in chain link 4 wears into a string with thimble 1, inner shield ring 10, side plate 5, axle sleeve 6, baffle ring 7 it, and leaving suitable expansion clearance, inner shield ring 10 is imbedded grate plate 2 sides and is prevented thimble 1 and lining 9 plaies, and is screened by grate plate 2.The axle two ends are fixing with snap ring 8, and lining 9 adopts the alloy pipe of hardness between chain link and major axis to make, and endoporus termination rounding, major axis then adopt cold rolling alloy garden steel, and cylindrical need not processed, and makes its manufacture simplification, and is easy to assembly.The chain link pitch is controlled, also can not cause aforementioned damage of major axis and destructive dismounting.
Claims (1)
1. the drying grate flexible axle bed of combing, comprise chain link, chain link lining, grate plate, side plate, major axis, thimble, back-up ring, snap ring, it is characterized in that: between chain link (4) and major axis (3), be provided with a lining (9), with lining (9) chain link (4) is linked to be string, described lining and chain link adopt little gap movingly, with between centers be big gap movingly, inner shield ring (10) is imbedded grate plate (2) side and is prevented thimble (1) and lining (9) play, major axis (3) adopts elongated flexible axle construction, and axle head adopts snap ring (8) fixing.
