Description

(54) KNOT OF FIXING THE BANDAGE ON THE HOLE OF THE ROTATING DRUM

one

The invention relates to cylindrical kilns, pelletizers, mixers and other devices, which are hollow rotating cylinders supported through shrouds on support rollers.

The connection of the bandage with the rotary kiln body is known, which is provided by the shoes mounted on the stops attached to the kiln body I.

However, such a connection does not ensure the correct selection of the thermal gap, does not eliminate the possibility of the occurrence of one or more pads, shoes, exceeding the rest in the connection.

The closest to the technical essence and the achieved result to the proposed is a node for mounting a bandage on the case of rotating, its drum, -containing stops rigidly attached to the case of the drum, located between the bandage and the case of the drum elements 2.

In a known node, the choice of the gap in the connection of the bandage with the body, ensuring

uniform distribution of the wedge gaskets along the height JB of the zone of contact of the band with the body is achieved by installing spring elements between the stationary stop and the end of the movable wedge. Such a connection includes at each point of contact a pair of wedges, one of which is movable and the other is rigidly connected to the body and is the base of the movable wedge.

However, this device has extra elements in the form of a fixed wedge,

10 which complicates the design and reduces its reliability.

The purpose of the invention is to simplify the design of the connection unit of the band with the body, improving the reliability of attachment.

This goal is achieved by the fact that the node

15 of the fastening of the brace on the rotating drum body, containing the stops rigidly fixed on the drum body, movable shoes with wedge 20 bevels located between the bandage and the drum case, and spring-loaded elements fixed between the shoe ends and stops, between which are placed movable shoes, and the inner surface of the band is made with a wedge bevel in contact with the wedge bevels of the shoes.

FIG. 1 shows the node, obsh, iy kind; in fig. 2 is a section A-A in FIG. one.

On the side of the body 1, the guide 2 are welded, in which the shoe 3 moves, pushed by spring elements 4 located between the stop 5 and the end of the shoe 3. The spring 6 from the assembly prevents the pin 6 entering the longitudinal opening of the shoe 3. The inner surface of the band 7 is made with a wedge bevel whose slope is equal to the slope of the movable base 3. The stops 8 prevent the movement of the band 7 along the body 1.

Due to the direct coupling of the wedge surfaces of the band 7 and the movable shoe 3, the need for manufacturing and assembling a fixed wedge is eliminated, which simplifies and reduces the cost of the design of the connection unit of the band 7

with a drum housing 1 and increases the reliability of his work and the entire machine.
