Description
Technical field
The utility model relates to the cement rotary kiln technical field, particularly relates to a kind of kiln tail sealing device of cement rotary kiln.
Background technology
At present, when the rotary kiln device work of burning clinker of cement, cylinder of rotary kiln is certain angle of inclination, causes rotary kiln that the displacement of trace is easily arranged in the axial direction, cause rotary kiln being connected sealing place generation certain interval with other equipment, gas leak phenomenon occurs, and therefore, has increased the exhaust blower load, grog thermal energy consumption and production cost have been improved, simultaneously, cause dust to overflow, pollute production environment.What existing cement rotary kiln tail Sealing Technology was used is the cylinder seal device, due to kiln end temperature generally at 200-300 ℃, the tracheae of cylinder seal matched with devices at high temperature is easy to aging, the cylinder seal package unit needs compressed air that power is provided, cost and production run cost are higher, more the cycle of scavenge trunk needs 5-6 days, causes very large puzzlement for the production of rotary kiln.
Summary of the invention
The utility model provides a kind of kiln tail sealing device for cement rotary kiln for the deficiencies in the prior art, has simple in structurely, and assembling is compact, and good airproof performance is safe and reliable, invest little, long service life, the characteristics that the rotary kiln running rate is high.
The technical scheme that kiln tail sealing device for cement rotary kiln of the present utility model is taked is:
A kind of kiln tail sealing device for cement rotary kiln comprises rotary kiln and spring fastening 1, spring 2, fixing seal ring 3, rotary seal ring 4, cylinder of rotary kiln 5, sealing stay thimble 6, sealing bracing wire 7, sealing counterweight 8, counterweight support bar 9.Fixing seal ring 3 is arranged on kiln tail and spring fastening 1, spring 2 is arranged between fixing seal ring 3 and kiln tail and spring fastening 1, rotary seal ring 4 is assemblied on the base of cylinder of rotary kiln 5, fixing seal ring 3 relatively seals with rotary seal ring 4 and contacts, upwards rotate at cylinder of rotary kiln 5 and be provided with sealing stay thimble 6 on the rotary kiln of a side and spring fastening 1, cylinder of rotary kiln 5 sides in sealing stay thimble 6 the same sides are provided with counterweight support bar 9, and sealing bracing wire 7 connects sealing stay thimbles 6 and sealing counterweights 8.
The utility model beneficial effect is: kiln tail sealing device for cement rotary kiln is owing to having adopted the brand-new technical scheme of the utility model, compared with prior art, the utlity model has following characteristics: 1, overall structure is simple, assembling is compact, good airproof performance, safe and reliable, invest little, long service life, versatility is good; 2, except adopting spring to improve sealing effectiveness, upwards rotate a side at cylinder of rotary kiln, on the rotary kiln of easy increasing fixing seal ring and rotary seal czermak space one side and spring fastening, the sealing stay thimble has been installed when being cylinder of rotary kiln generation displacement, by increasing counterweight, circulating application adds external relay to fixing seal, has further improved the sealing property of rotary kiln.
Description of drawings
Fig. 1 is kiln tail sealing device for cement rotary kiln structural representation of the present utility model.
Fig. 2 is the right view of Fig. 1.
In figure, 1, rotary kiln and spring fastening, 2, spring, 3, the fixing seal ring, 4, the rotary seal ring, 5, cylinder of rotary kiln, 6, the sealing stay thimble, 7, the sealing bracing wire, 8, the sealing counterweight, 9, the counterweight support bar.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, kiln tail sealing device for cement rotary kiln of the present utility model comprises rotary kiln and spring fastening 1, spring 2, fixing seal ring 3, rotary seal ring 4, cylinder of rotary kiln 5, sealing stay thimble 6, sealing bracing wire 7, sealing counterweight 8, counterweight support bar 9.Cylinder of rotary kiln 5 is certain angle of inclination, kiln tail bearing is located at the low side of cylinder of rotary kiln 5, kiln tail bearing is also the bearing of spring simultaneously, and fixing seal ring 3 is arranged on kiln tail and spring fastening 1, and spring 2 is arranged between fixing seal ring 3 and kiln tail and spring fastening 1.Rotary seal ring 4 is assemblied on the base of cylinder of rotary kiln 5, and fixing seal ring 3 relatively seals with rotary seal ring 4 and contacts.Upwards rotate at cylinder of rotary kiln 5 and be provided with sealing stay thimble 6 on the rotary kiln of a side and spring fastening 1, be provided with counterweight support bar 9 on cylinder of rotary kiln 5 sides of sealing stay thimble 6 the same sides, sealing bracing wire 7 connects sealing stay thimbles 6 and sealing counterweights 8.
Operation principle: kiln tail sealing device for cement rotary kiln of the present utility model installs when rotary kiln is static, spring 2 is adjusted to is in compressive state, add suitable sealing counterweight 8, at this moment, fixing seal ring 3 and rotary seal ring 4 compact state of upwards fitting in the rotary kiln footpath.during the rotary kiln normal operation, rotary kiln is around its axial-rotation motion, fixing seal ring 3 and rotary seal ring 4 relatively rotate, spring 2 is pushed fixing seal ring 3 to rotary seal ring 4, make it keep relative gluing, sealing contact, there is the effect of certain gradient and self rotation due to rotary kiln and horizontal line, rotary kiln has the displacement of trace, upwards rotate a side at cylinder of rotary kiln 5, fixing seal ring 3 can produce larger gap with rotary seal ring 4, only there is the thrust of spring 2 also to be not enough to eliminate this gap, therefore taked the gravity tractive measure of sealing counterweight 8, the strength of fixing seal ring 3 to 4 displacements of rotary seal ring has been strengthened in the part, guarantee that fixing seal ring 3 and rotary seal ring 4 all are in good sealing in the rotary kiln radial periphery.
