    A heated controlled deflection roll equipped with spraying devices arranged in the intermediate space or compartment between the stationary roll support and the roll shell. The spraying devices have walls confronting the inner surface of the roll shell and at which walls there are formed openings which, during operation, form liquid jets. Oil which is infed to the spraying devices can be heated in a collecting container and/or in a tubular conduit. Temperature regulation of the roll shell can also be accomplished by a throughflow or quantitative regulation by means of valves. If there are present a number of temperature zones in the lengthwise direction of the roll shell then different spray devices can be operatively associated with partition walls, from which the liquid is infed to separate collecting containers. From these collecting containers the liquid is again infed, by means of separate pressure lines, to the individual spray devices.

    The invention relates to equipment for the processing of polymeric materials on roller machines, in particular on rolls with adjustable deflection.
    A roll with adjustable deflection is known, comprising a stationary support and the end of a hollow body mounted rotatably on it, which forms an annular gap with a stationary support Cl}.
    However, in such a roll there is no supply to the internal surface of the coolant body.

    However, in a known roll, heat transfer from is not optimal. the heat carrier to the roll's perfection, as the jets of the latter formed by the device for supplying the liquid heat carrier do not have a KONfv compact form due to the fact that the heat carrier disperses, while the heat transfer from the heat carrier to the heated surface decreases. is coming.
    The purpose of the invention is to increase the heat transfer rate from the coolant to the heated roll surface.
    The goal is achieved by the fact that in a roll containing a stationary support, a hollow body concentrically mounted on it with rotation, forming an annular gap with a stationary support, and mounted on it along the axis
    The roller is a device for supplying temperature controlled heat transfer fluid to the inner surface of the roll housing, which is connected through a supply pipe to the coolant reservoir and has a series of holes in its side wall to form normal liquid side jet bodies that are normal to the side wall of the roll body. supply of heat-transfer fluid is made with box-shaped cross-section and openings to form a compact jet
    5 and provided with a parallel arrangement, but with a number of additional
    rows of holes to form
    compact jet, with holes
    offset relative to one another
    , in adjacent rows, the distance between,
    adjacent holes mi selected within 5-10 of their diameters, and the direction of the longitudinal axes of the additional holes selected coinciding with the direction of the normal to the side wall of the housing or with a deviation from the normal, the angle of which is chosen to be no more than 30 °.
    In this case, the distances between the holes and / or the diameters of the latter are chosen different along the length of the roll, depending on the required intensity of heat transfer to the surface of the pole.
    5 In addition, the distance of the holes to the inner surface of the housing is selected in the range of 4-10 hole diameters.
    At the same time, the device for supplying a heat transfer fluid consists of several sections along the length, and the heat transfer fluid reservoir consists of several chambers for a heat transfer fluid with different temperatures connected to the corresponding sections of the flow heat transfer fluid supply through individual pipelines. In this case, the pipeline for supplying the heat-transfer fluid from the tank is made with branches, each of which is provided with a means for controlling the temperature of the roll with a choke for controlling the flow of the heat-transfer fluid and the temperature controller and is connected to the corresponding section of the fluid-heat transfer fluid. In addition, it is equipped with transverse partitions for partial separation of the body cavity into sections mounted in the lower part of the stationary support and located in the annular gap of the roll at the boundary of the sections of the device for supplying heat transfer fluid and the discharge pipes of the housing with chambers . In this case, the side wall with holes is made flat or convex. i Fig 1 shows the proposed roll; general view; in fig. 2, section A-A in FIG. one; in fig. 3 - the same, an embodiment of the device for supplying a heat-transfer fluid; Fig. 4- shows an embodiment of the roll in fig. 5 and 6 are embodiments of holes in the side wall of the device for supplying a heat transfer fluid; in fig. 7 - heating device. The roller contains a stationary support 1 and a hollow body 2 which is concentrically mounted on it with the possibility of extension, mounted on a support in 3 rolling bearings. The ends of the housing 2 are closed by discs 4 with seals 5. The hydrostatically supporting pistons 6 are sealed in the support. On the support 1 along the roll axis there is a device for supplying a heat-transfer fluid with temperature adjustable to the inside surface of the roll housing, which is made with box-shaped cross section and has located on its side wall 7, facing the inner surface 8 of the housing 2, the apertures 9 to form compact jets 10 of liquid. The housing 2 forms an annular gap 11 with a stationary support. In the lower part of the housing 2, a sump 12 of liquid is formed, which is connected to the reservoir 15 for the coolant through the branch pipe 13 and the outlet line 14. In the branch line 14, a pump 16 can be installed. In the tank 15, a heating device is installed which is configured as a coil 1 with a valve 18. A regulator 19 is used to control the valve, which is connected to the temperature sensor 20. A heating device for lower temperatures is operated with hot water or steam. For higher temperatures, resistive heating may be anticipated. The valve 18 is replaced with a corresponding switch (not shown). The container 15 through the supply pipe 21 with the pump 22 is connected to the fitted. by supplying a heat transfer fluid that is made up of several sections in length. In this case, the supply pipe 21 has branches 23 (FIG. 1) for supplying; heat transfer fluid from tank 15 to each of the sections. Each branch has means for controlling the temperature of the roll, which includes a choke 24 and a temperature controller 25 connected to the sensor 26, which are mounted on the surface of the housing 2 of the roll, opposite each of the sections of the fixture supply of heat-transfer fluid. From pressure vessel 15 a pressure line 27 comes out with a pump 28 and a pressure control device; hydrostatic support elements b, which includes the i 29 bypass line with control valve 30 ,. the controlled regulator 31 depends on the readings of the device 32 for measuring pressure. In the embodiment of FIG. 1, the support hydraulic medium is simultaneously used as a heat transfer fluid for spraying. On the branches 23 of the pipeline, a heating device (FIGS. 4 and 7) can be installed instead of the throttle 24 or with it. The heating device includes a serpentine 22 or a heating coil (not shown) and a temperature controller 34 associated with the motor 26. In the cavity of the housing 2, transverse partitions 35 can be installed to partially divide the cavity of the housing into sections a, b and c. Partitions 35 Installed at the bottom of the clock. These stationary supports 1 and are located in the ring 10 at the border of the section of the device for supplying the heat-transfer fluid. At the same time, the sections 0.13 and c are connected to the sec- dy, mi d, C, and f of the tank 15 by means of discharge pipelines of the line 14 with pumps 16 on each of them. Sections d, e and f are connected to the corresponding sections of the device for supplying heat-transfer fluid through individual pipes 36 to pumps 37. Sections "3, e and f of tank 15 are intended for heat transfer fluids with different temperatures. The holes 9 are made in the form of nozzles and are located in the side wall in several rows. In this case, the axis of the hole in the central row is directed along the normal to the side wall of the roll housing. The axes of the hole in additional rows can be directed either along the normal to the side wall (the right part of Fig. 2), or deviated from the normal by an angle ct, which is chosen to be no more than 30 ° (the left part of Fig 2). The side wall 7 can be either flat or convex (Fig. 2). Holes 9 are offset relative to each other in adjacent rows. The distance A and A between adjacent holes 9 are chosen equal to Sr-1O and their diameters P- or D, respectively. At this distance between the openings 9 can be chosen different along the length of the pole depending on the required intensity of heat transfer to the surface of the roll. The number of rows with openings 9 in the sections of the supply device can be different as well as the diameters D and D2 holes. For example, the central section (fig. B) has a smaller number of rows of holes than the extreme sections (fig. 5, as it is usually necessary to supply more heat to the butt ends of the wafer due to large losses on the roll surfaces. Spacing L holes 9 to the inner surface of the casing is selected to be 4-10 diameters of D; and the openings 9, a pressure chamber (FIG. 3) may be provided between the support 1 and the housing 2, which is closed by a plate-shaped sealing element 38. A device for supplying a heat-transfer fluid may made as n Call 39 in support 1 or in the form of a box 40. The roller works as follows, To a roll from a tank 15, which has the desired temperature, by pump 22 or 37 (Fig. 4) through the inlet pipe 21 and branch 23 (FIG. 1) and The pipelines 36 (Fig. 4) are supplied with a heat transfer fluid, which falls into the sections of the coolant supply device to the inner surface of the roll housing. In this case, the regulator 25 with throttles 24 ensures the regulation of the flow rate of the fluid so that individual sections of the heat carrier supply The last spray is sprayed onto the surface of the roll housing 2 through the holes 9 with the same temperature. The sensor 26 is given an appropriate command to the controllers 25 and heaters (Fig. 4). In this case, a device for transferring the heat-transfer fluid provides a large amount of the latter to the surface of the roll with a high relative speed, which ensures good heat transfer. The selected shape of the holes and their relative location ensured the uniformity of the thermal effect, in particular, the heating of the VSka housing. The arrangement of holes in several rows enhances the effect of heat transfer. The chosen length of the jet ensures its compactness, which also improves the transfer of heat to the roll. The arrangement along the roll body of several sections with openings for the formation of compact jets and the connection of sections to separate sections of the tank for a heat carrier with different temperatures provides independent control of temperature along the length of the roll housing. Performing the supply of fluid to the roll from the same unit, but along several branches, having independent control of the temperature of the supplied fluid (Fig. 4) or coolant flow (Fig, 1), depending on the required temperature of the roll, provides an economical mode of operation of the roll . The presence of dividing transverse partitions 35 prevents displacement of the flow of the heat-transfer fluid with different temperatures, which reduces, for example, the cooling of the heat-transfer fluid. Thus, the use of the invention improves the efficiency of the heat treatment process and increases the heat transfer from the coolant to the roll surface.
