Description

one

The invention relates to the building materials industry, namely, devices for securing the block lining to the body of a rotary kiln, and can be used in any industry where rotary kilns are used.

According to the main auth. A device for fastening a block lining is also known as 726398. The device comprises a stop element fixed on the furnace body, made in the form of a plate with edges perpendicular to the furnace axis, and a fixing anchor rigidly attached to the stop element Cl 1, 5

As shown by the exploitation of the operation of the block concrete lining at the hot end of a large rotary kiln, the blocks were fixed to the casing using a known device 20, when one of the blocks and brick lining adjacent to the block ring were destroyed, a shift occurred (5 blocks along the kiln). aside

tivopoluyu a working face of a persistent element. Along with this, during the renovation of the lining, when the brickwork, adjacent to the blocks, is removed, and at least one block is missing in the ring, then at the back of the kiln there occurs a corner of the axes of the blocks parallel to the kiln.

With significant displacement and reversal of the blocks, it is not possible to return them to the original shelving, which makes it necessary to break concrete blocks out of the furnace, which reduces the duration of the lining operation.

The purpose of the invention is to increase the service life of the lining.

Claims (1)

This goal is achieved by the fact that the device for fastening the block lining is provided with one or several stops welded to the furnace body and placed in the front part of the block, while the working face of this stop (or stops) is perpendicular-. It is located on the furnace axis. But Lig. 1 shows the furnace body, longitudinal section; FIG. 2 is a section A-A in FIG. 1. The device comprises a block 1 with a mount 2. At the end of the block 1, a recess is made into which, after attaching the block to the furnace body, the stop 3 is inserted and welded to the furnace body. Each block can have one or several stops. The stop 3 is welded to the pSr furnace body, leaving a gap of about 3 °; rum 3 leaving a gap S, compensating for it. At the same time, it works as follows OBPGLR / GTAYG. V, m RA «1, p. thrust element 2, screwing in the fastening anchor, tightening the nut through the washer and pouring the seat in block 1 with hot concrete block block lining is ready to accept axial loads. f- The face of the stop element 2 works by holding, keeping the axial movement of the entire brickwork. The radial movement of the block is limited by a shank and a nut mounted on the mounting anchor. Weld abutment (stops 3) prevents the movement of blocks 1 along the furnace axis, and also makes it impossible to break the parallelism of the axes of the blocks along the axis of the furnace both during furnace operation and during lining repair, which increases the service life of a concrete Luther 1.5 -2 times. The invention The device for fastening block lining auth.St. W 726398 USSR is characterized in order to increase the service life of the casting, IT is provided with one or several stops welded to the furnace body and placed in the front part of the block, while the working face of this stop (or the stops) is perpendicular to the furnace axis.
