SU1408178A2 - Rotary furnace seal - Google Patents

Abstract

The invention relates to rotary kiln seals and can be used in the cement industry, ferrous and non-ferrous metallurgy when burning lime, dolomite, refractories and other materials. The purpose of the invention is to increase the reliability of compaction and reduce the labor intensity of manufacture. For this, the rotary kiln seal contains a sealing ring of separate flexible elements 2, each of which is made with an S-shaped bend on one of its sides for connection with an adjacent element. The flexible elements 2 are interconnected by hollow flared rivets and, on the one hand, are hinged to the cooler's visor and, on the other hand, to the beads with the fittings that form the contact ring around the furnace body. During operation and rotation of the furnace, the warping and kink of flexible elements are eliminated under the action of constant alternating loads, and the tight placement of the layers of elements in an accordion eliminates hard edges in places of bending. 6 Il. from 8 cl

I The invention relates to seals, a furnace, can be used in the cement industry, ferrous and non-ferrous metallurgy when burning lime, dolomite, refractory materials and other materials and is an improvement of the invention according to the author. St. No. 1024673.

The purpose of the invention is to increase the reliability of compaction and reduce the labor intensity of preparation.

i FIG. Figure 1 shows the rotary kiln seal, cross section; on 1FIG. 2 is a section A-A in FIG. one; in fig. 3 - | bb section in FIG. -2; in fig. 4 is a view B ha of FIG. 3; in fig. 5 - sweep flexible element; in fig. 6 - section of GG on игг. four.

The seal of the vrashuy furnace contains a sealing ring 1 of individual flexible elements 2, each of which is made of a single sheet with an S-shaped

The cable 19 with weights 20 and 21 is intended to hold the upper part of the sealing ring 1 against the furnace body 11.

The fabrication of the flexible elements 2 includes the following operations: marking the sheet, 5 bending it along two faces into an accordion, crimping the edges formed, drilling holes, flared hollow rivets 3.

10 Seal vrashuyu furnace works as follows.

During rotation and radial beats of the furnace body, the flexible elements 2, together with the beads 10, pressed against the furnace body by cables 12 and 19, elastically deviate from

 5 starting position. The implementation of flexible elements 2 from a single sheet with an S-shaped bend on one of the sides eliminates warping and fracture of the plates under the action of a constant sign of the bend on one of its lateral 2Q heavy loads, and the laying of layers is tight

Parties to connect with the neighboring element.

 The flexible elements 2 are interconnected at the ends by means of hollow flare rivets 3. Using bolts 4 Z with nuts 5, flexible elements through holes in hollow rivets 3 are hinged to the visor 6 welded to the wall of the refrigerator 7, and with the help of bolts 8 and nuts 9 are also hingedly attached to Zusinam 10, cast from an aluminum alloy, containing embedded parts ja as wear-resistant elements and solid lubricant. The beads 10, matching each other with depressions and protrusions, form an ontact ring around the body 1 of the rotating furnace. Cable 12, blocks 13-16, group 25

elements in “accordion eliminates hard edges in places of bending, which increases the flexibility of elements.

In the proposed seal design, air is prevented from flowing through the flexible elements 2, thereby increasing the reliability of the seal and reducing the complexity of its manufacture.
