The invention relates to seals of a Rotary kiln, can be used in the cement industry, and is additional to the main ed. St. USSR № 1024673.

 The chain of the invention is the increase in durability.

Figure 1 shows the seal

rotary kiln, general view; in FIGS. 2-0, a safety valve and an A-A sealing in FIG. 1. The rings, equal to 0.55-0.5 times the maximum radial beating of the furnace, allow functioning

 The rotary kiln seal contains a sealing ring 1, consisting of a flexible element 2. With the help of

 flexible element 2 without violations.

1bolts and nuts flexible hinge elements- 5 occurrence of a large vacuum

JHO attached to the visor 3, welded to the wall 4 of the refrigerator. On the other side, flexible elements are hingedly attached to cast aluminum: alloy beads 5 that mate with each other; 20 With other depressions and protrusions, a contact ring around the frame 6 of the rotary kiln. The cable 7 through blocks 8-11 with weights 12: and 13 provides the pressing of the lower part of the sealing ring 1 to the sidewall 6, the cable 14 with the help of weights 15, 1.6 is designed to press the upper part of the sealing ring to the sidewall 6 rotary kiln. Under the 30th sealing ring, at its average diameter, at a distance of 0.55-0.5 times the maximum beating of the radial beat of the furnace, a safety ring 17 with spikes 18, which are split on it, is installed;

Claims (1)

In the sealing gap, the flexible elements 2 bend inwards and along the average diameter of the sealing ring 1 lie on the safety ring, which allows to eliminate the further deflection of the elements, their distortion and ruptures. This preserves the flexibility and mobility of the elements of the sealing ring. Claims of the invention, Seal of the rotary kiln according to ed. No. 1024673, characterized in that, in order to increase the resistance of the seal, it is provided with a safety ring mounted on the average diameter at a distance of 0.55-0.5 times the maximum radial beating of the furnace from the inner surface of flexible elements ribs-rods attached to the visor of the refrigerator along its perimeter. The compaction of the rotary kiln operates as follows. During the rotation and radial runout of the rotary kiln 6 of the rotary kiln, the flexible elements 2, together with the beads 5, are pressed against the surface of the shell 6 with the cables 7 and 14, elastically deviate from the initial position. The gap between the flexible element 2 without violations. In the sealing gap, the flexible elements 2 bend inwards and along the average diameter of the sealing ring 1 lie on the safety ring, which allows to eliminate the further deflection of the elements, their distortion and ruptures. This preserves the flexibility and mobility of the elements of the sealing ring. Claims of the invention Sealing rotary kiln according to ed.St. No. 1024673, characterized in that, in order to increase the resistance of the seal, it is provided with a safety ring mounted on the average diameter at a distance of 0.55-0.5 times the maximum radial beating of the furnace from the inner surface of flexible elements ribs-rods attached to the visor of the refrigerator along its perimeter. 13 FI.1
