Abstract
A graphite contact-type sealing device of a rotary kiln consists of a pin shaft, a gasket, a pin, a press rod, a nut, a special-shaped nut, a bolt, a graphite block, a guide rod, a press plate, a spring, a spring seat, a cushion, a return spoon, a fixed barrel body and a rotating barrel body. One end of the return spoon is fixed on the rotating barrel body via the bolt, the nut, the gasket and the cushion, and the spring seat is welded on the rotating barrel body. The graphite bock and the fixed barrel body contact with each other all the time through a lever balancing device, thereby not only guaranteeing rotation lubricating effect of the barrel bodies, but also guaranteeing air tightness effect of the barrel bodies.
Description
Technical field
Between the kiln hood cover of rotary kiln and kiln hood and the rotating cylindrical shell sealing device is arranged, its objective is in order to reduce cool ambient air to enter in the kiln, prevent that also furnace air from carrying material and leaking simultaneously, improve the production capacity and the clinker quality of chamotte kiln, reduce various consumption.Therefore improving with improvement of seal of rotary kiln device just seems particularly important to the efficient operation of production equipment and the improvement of environment.
Background technology
At present, rotary kiln has flake type sealing device and friction plate sealing device with sealing device.The flake type sealing device, though simple in structure, because the unlubricated scale serious wear that causes influences sealing effectiveness; The friction-type sealing device is generally used lubricating oil (or lubricating grease) friction plate, the pipeline complexity, and under the higher environment of temperature, lubricating oil (or lubricating grease) easily evaporates and runs off, and is lubricated insufficient, quickens the wearing and tearing of friction plate, and the waste lubriation material influences environment.
Summary of the invention
In order to overcome the deficiency of existing kiln with sealing device, the utility model provides the contact seal of a kind of rotary kiln graphite.Its main feature is: 1. belong to the graphite contact seal, and good sealing effect, the while can be played the effect of oil-free lubrication.2. in the certain limit of kiln body beat, have automatic centering, cylindrical shell axially jump and circular runout little to sealing influence.
The technical scheme that its technical problem that solves the utility model adopts is: suitably give holddown spring pressure, observe the graphite block degree of wear, make graphite block with respect to fixed muffle neither press tension, do not throw off again.This device utilization lever balance theory must make that connecting rod is parallel to the kiln axis direction, thereby just can produce a desired effect.
The beneficial effects of the utility model are, the effect of using the graphite contact type sealing device still significantly, temperature of kiln head has had bigger rising, coal consumption can reduce significantly, thereby has guaranteed the improvement and the long-time running of kiln condition.

Fig. 3 is the B--B cutaway view of Fig. 1.
1. bearing pins among the figure, 2. packing ring, 3. pin, 4. depression bar, 5. nut, 6. special-shaped nut, 7. bolt, 8. nut, 9. packing ring, 10. support, 11. baffle plate, 12. graphite blocks, 13. fixed cylinders, 14. connecting rods, 15. guide rods, 16. nut, 17. pressing plates, 18. holddown springs, 19. bearings, 20. spring base, 21. pads, 22. bolts, 23. nuts, 24. packing ring, 25. feed back spoons, 26. rotary barrels, 27. drifts.
The specific embodiment
Among Fig. 1, an end of feed back spoon (25) adds that with bolt (22), nut (23), packing ring (24) pad (21) is fixed on the rotary barrel (26).Spring base (20) is welded on the rotary barrel (26).Bearing pin (1), packing ring (2), pin (3), depression bar (4), connecting rod (14), guide rod (15) and bearing (19) are formed a lever balance device, directly are welded on the feed back spoon (25) by bearing (19).In Fig. 2, baffle plate (11) is evenly distributed on a side of feed back spoon (25) by bolt (7), nut (8), packing ring (9), and support (10) is fixed on the same side of feed back spoon (25) by depression bar (4), nut (5), special-shaped nut (6) and baffle plate (11).Graphite block (12) places between two voussoirs (27), and by voussoir (27) adjustment of leading, baffle plate (11) plays fixing effect (see figure 3) simultaneously.But should guarantee certain clearance between baffle plate (11) and the graphite block (12), can make graphite block (12) with the frictional dissipation of fixed cylinder (13) after can adjust by the lever balance device.The concrete operations of lever balance device.
