Description

one

The invention relates to a structural element of rotary kilns of furnaces and can be used in the field of building materials for burning industrial waste and calcining various raw materials.

The aim of the invention is to increase the service life of the shell and lining.

Figure 1 shows the device of the end of a rotary kiln, in an axonometric projection; figure 2 is a view of And figure 1; on fig.Z - section bb in figure 2.

The device of the end face of the rotary kiln contains a shell 1 and a ring stop 2 rigidly attached to it

The protective plates 3, made in the form of a clique with a transverse groove 4 on its supporting surface, are mounted on the ring stop J with their grooves 4 with gaps that guarantee the possibility of thermal expansions, and with their end surface hold the lining 5 of the rotary kiln. The protective plates 3 are additionally attached to the shell 1 with the help of earrings 6, having the form of oval rings and passing through holes 7 and 8, respectively, respectively in shell 1 and protective plates 3 and with crossbars 9 with wedges IO and 1I .

Crossbars 9 and wedges 10 and 11 are made with slots 12 and 13, corresponding to the profile of earrings 6, which include earrings 6.

The grooves 12 and 13 prevent longitudinal movement of the bolts 9 and wedges 10 relative to the earrings 6. The wedges of IO and 11 are fastened to each other from the side of the wedge 10 of the point

by welding, in order to prevent spontaneous wedging when elongating the earrings 6 when the rotary kiln is heated.

5 The device operates as follows.

Install the protective plate 3 on the pre-fixed ring stop 2, aligning the holes

to 7 and 8 on shell 1 and protective

the plate 3, the earring 6 is inserted into these holes, and the bolt 13 is threaded into them with the groove 13. From the outside, the shell 1 is inserted into the earring 6 with the groove

t5 12 wedge 10 and using the wedge 11 secure the protective plate 3.

Similarly, all the other protective plates 3, except the last, are installed opposite the locking row of lining 5 of the rotary kiln. After laying the castle row of lining 5 install the last protective plate. After installing all protective plates 3 wedge 10 and

25 are fastened together by spot welding.

The proposed end face design of the rotary kiln does not require mechanical treatment of the protective plates, and

30, their individual attachment to the shell of the rotary kiln eliminates the possibility of their movement along the ring stop when the kiln rotates and the radial movement of the protective plates to the center, does not create difficulties in installing a lock row of lining. In addition, fastening the protective plates to the shell with wedges ensures easy installation and disassembly.

40 devices without lining damage, while increasing the service life of the shell and lining.
