Description

Rolls for roller machines are known, comprising an outer shell mounted on trunnions and an inner shell made with a spiral partition for circulating a heat transfer fluid.

In the known rolls, it is not provided on the inner shell of a heat insulating gasket that carries a removable spiral partition, which reduces the intensity of heat exchange of these rolls and does not ensure cleaning of heat exchange surfaces from contamination.

The proposed roller is characterized in that the spiral partition is a removable tape radially mounted along the outer and inner edges in the spiral grooves made on the inner surface of the outer shell and on the supporting elastic monolithic strip worn on the inner shell.

The roller is also distinguished by the fact that the supporting elastic gasket is formed from a glass fiber reinforced polymer material, for example rubber, and is made in the form of a hollow spiral hose filled with pressure from the working medium with a recess reinforced by a metallic coating iodine inner edge of a removable spiral tape partition.

made of steel spring tape, as well as of a polymeric material, such as polyethylene.

This roller provides an increase in the intensification of heat transfer and facilitates the cleaning of heat exchange surfaces from contamination.

FIG. 1 shows a swath with a partial longitudinal section; pas figs. 2 is the same, end view; in fig. 3-end of the roll in the enlarged

scale with a partial longitudinal section; in fig. 4-roll with part-length longitudinal section, one of the embodiments of the sanding elastic strip; in fig. 5-part of the roll in an enlarged scale in the longitudinal

section; in fig. 6-part of the outer shell with a removable siiral tape-wall and a supporting elastic pad during their assembly (disassembly).

Roller to roller machines, used to

rollers, contains mounted on pins} by means of spokes 2 and heat carrier supply pipes 3, outer 4 and inner 5 shells, connected by spring rings 6 n 7 with gap 8 for circulation

tenon carrier in a spiral partition 9, made on an inner shell 5.

Spiral partition 9 is a removable tape radially mounted on the outer W and inside the w / edges

on the inner surface of the outer shell 4 and on the carrier elastic monolithic gasket 14, put on the inner shell 5.

The elastic support strip 14 is formed of a glass-fiber-reinforced polymer material, for example rubber, of a polymer material, preferably containing polyesters, and is in the form of a hollow spiral hose 15 filled with pressure working medium, such as oil, water or compressed air. covered with a metal coating 16 under the inner edge 11 of the removable spiral tape-partitions U.

Tape-partition 9 is made of steel spring tape, but can be made of a polymeric material, for example of polyethylene.

In the gap 8 between the rings of rings 6 and 7, an adjusting ring 17 is inserted, the outer and inner surfaces of which, radially directed, have the same taper as the surfaces 18 and 19 of the spring rings 6 and 7.

The adjusting ring 17 has several holes 20, the axial line of which is parallel to the hydrodal line of the roll. Through the central holes of the setting rings J7, bolts 21 fitted with heads 22 are fitted with a large gap, and these bolts are adapted to be screwed into the ring nut 23. A gasket 24 made of rubber or another suitable elastic material is located between the ring nut 23 and the spring rings 6 and 7. .

An annular gap 8 formed by the outer and inner shells 4 n 5 is connected by means of tubes L with a cylindrical cavity 25. With the help of a discharge valve 26, the intruded part 27 of the sleeve 15 is filled under pressure with working medium, for example compressed air, water or oil. In order to ensure the correct positioning of the spiral turns of the sleeve 15 on the inner shell 5, the fixing screws 28 with nuts 29 are used occasionally (not necessary), the same attachment of the turns of the sleeve 5 should be done with the help of spring rings b and 7 when fed to the working medium sleeve under pressure.

The proposed roll can be used in heated rollers using

as a heat carrier for hot water or steam.

The drawings show one of the variants of a roll, in particular a roll cooled by water, made with a diameter of about 500 mm

and the thickness of the walls of the outer and inner shells about 4-6 mm. Water is fed through the cavity 25 of the trunnion 1 through the tubes 3 into the gap S between the shells 4 and 5 and the turns of the spiral tape partition 9 with recirculation through the tubes and the axle cavity installed at the other end of the roll, and with continuous water for cooling cooling the roll to the set temperature.
