Problems solved by technology

[0003] For this reason, the object of the present invention is to provide a rotary kiln tail seal to prevent cold wind from entering the preheater, which can completely solve the problem that the swing seal is not tight due to the change of resistance caused by the change of the center height with the swing amplitude

Embodiment Construction

[0013]The present invention will be described in detail in connection with the accompanying drawings and examples in conjunction with the drawings and examples.

[0014]A rotary kiln kiln tail anti-cold wind enters a preheater sealing device, such asfigure 1 As shown, the horizontal orbit 12 and the track base 13 homogenerate, the roller 11 is a cylinder, and when the roller 11 rolls back in the horizontal rail 12, the center of the roller 11 can be maintained. Will not change. The kiln tail cigarette chamber fixing sleeve 4 is fixed to the kiln tail tunnel 3, the center line of the kiln tail tobacco compartment fixing sleeve 4 is coincident with the centerline of the rotary kiln cylinder 10, the ring seal 9 seals the fixing friction ring 5 and the kiln tail The smoke room fixes the gap between the sleeve 4 to prevent the gap. The roller shaft 16 is rigidly attached to the screw buckle link 15, and then the fixing friction ring 5 is rigidly attached, and the fixing friction ring is fix...

Abstract

The invention discloses a sealing device for preventing cold air from entering a preheater at the tail of a rotary kiln. The sealing device comprises a rotary kiln cylinder, a kiln tail smoke chamber and a kiln tail smoke chamber fixing sleeve fixed on the kiln tail smoke chamber, wherein a fixed friction ring sleeves the smoke chamber fixing sleeve, and a gap between the fixed friction ring and the kiln tail smoke chamber fixing sleeve is sealed in an annular sealing manner; a movable friction ring is fixed on the rotary kiln cylinder, a horizontal track is arranged on the kiln tail smoke chamber of the rotary kiln, a rolling wheel is arranged on the horizontal track, and the rolling wheel is arranged on a rolling wheel shaft; the center of the fixed friction ring coincides with the center of the kiln tail smoke chamber fixing sleeve and also coincides with the center line of the rotary kiln cylinder; and under the action of self-gravity of a counterweight hammer, a steel wire rope drags the fixed friction ring to be always in close contact with the end surface of the movable friction ring through a fixed pulley. According to the sealing device, the problem of kiln tail sealing and air leakage can be well solved, coal consumption of the rotary kiln can be reduced, the energy is saved, and the structure is simple.

Description

Technical field[0001]The present invention relates to the field of calcination of the rotary kiln, and in particular, a rotary kiln kiln tail preventing air enters a preheater sealing device.Background technique[0002]In the cement industry, there are many kiln tail seals in the rotary kiln to be sealed by end-faced gravity rings. This structure is a fixed friction ring that moves horizontally along the centerline horizontal movement along the hinged seat. The weight of the friction ring falls on the hinged seat, and is not on the kiln tail tobacco compartment fixing sleeve, and the fixed friction ring double-sided boom is increased in the middle of the separation structure to increase the adjustment screw can be a good correction of the fixed seal ring and the cylinder coaxial Degree, thus reducing a large friction force due to the weight of the friction ring falls on the fixed sleeve of the kiln tail tobacco room, so that the resistance of the friction ring is reduced; the friction...
