Definitions

  • a sealing device for a web of material during its continuous passage through a pressure container comprising roller means which are rotatably mounted at a frame and which can be pressed against one another. These roller means are disposed at opposite sides of the web of material.
  • roller means are sealed, on the one hand, by plate members which cooperate with the end faces of said roller means, and, on the other hand, by means which bear with pressure against the outer surface of the roller means.
  • the roller means can be urged directly or indirectly against support means which are fixedly secured to the frame means by utilizing the action of pressurized fluid medium actuated piston means.
  • Pressurized fluid medium actuated piston means serve to urge the roller means towards the fixedly secured support means
  • at least one additional pressurized fluid medium actuated piston means serve to urge the roller means against one another.
  • the pressurized fluid medium actuated piston means are utilized to selectively space the roller means from the support means.
  • the present invention relates to a new and improved sealing device or apparatus for a Web of fabric or cloth during its continuous passage through a pressure container or vessel, and is of the type incorporating roller members which are disposed to both sides of the web of fabric.
  • These roller members can be pressed against one another and are rotatably mounted in a frame unit.
  • these roller members can be sealed by plate members which cooperate with the end faces of the roller members and furthermore by means of suitable elements, as will be explained hereinafter, which bear under pressure against the surface of these roller members.
  • Webs of any suitable material such as for instance, textile webs can be treated during continuous passage in such pressure containers, whereby these webs are processed, for instance, with saturated steam. It is known to those skilled in the art that the reaction time during fixing of colors or dyes and during bleaching operations is considerably shorter if the temperature of the saturated steam exceeds 100 C. However, this results in an over pressure existing in the container or vessel, so that special sealing problems arise.
  • sealing materials are quite limited for chemical and physical reasons.
  • the materials which can be employed are not particularly resistant to wear and, therefore, possess a relatively short life span or longevity during operation.
  • Another, more specific object of the present invention relates to an improved sealing device for a web of fabric during its continuous passage through a pressure container, which not only is extremely effective in carrying out its sealing function, but is constructed in such a fashion that the sealing elements can be easily replaced should they become worn, without necessitating the performance of complicated dismantling operations.
  • Still a further object of this invention relates to an improved sealing device wherein the sealing locations can be quickly and easily cleaned should it be necessary, for instance, to convert to a different type of treating process.
  • Yet a further significant object of the present invention relates to an improved sealing device of the type described which renders it possible to quickly and simply replace worn-out sealing elements without undertaking any cumbersome and time consuming dismantling of the machine.
  • the inventive sealing device is manifested by the features that the roller members can be pressed directly or indirectly against support means which are stationarily or fixedly secured at the frame unit of the machine, by utilizing pressurized fluid medium actuated piston means, and further at least one pressurized fluid medium actuated piston means serves to press the roller members against one another.
  • the pressurized fluid medium actuated piston means serve to space the surface or jacket of the roller members from the support means and from one another.
  • FIG. 1 is a schematic longitudinal sectional view through a preferred embodiment of inventive sealing device
  • FIG. 2 is a cross-sectional view of the sealing device depicted in FIG. 1, taken along the line II-II thereof;
  • FIG. 3 is a cross-sectional view, similar to that shown 3 in FIG. 2, but depicting a dilferent position for the roller means or members;
  • FIG. 4 is a cross-sectional view, similar to that shown in FIG. 2, but of a further embodiment of inventive sealing device.
  • FIG. 5 is a variant of a detail of the sealing device shown in FIG. 1.
  • inventive sealing devices which have been shown, by way of example, are each secured to the upper end of an associated pressurized vessel or container, the latter having been conveniently omitted from the drawings in order to preserve clarity in illustration.
  • the various sealing devices designed according to the invention serve for sealing the drive roller members for a web of material which is moving into or out of the associated pressurized vessel.
  • Each of the embodiments of inventive sealing device incorporates a stationary frame means or unit which is composed of the members 1 to 6, as best shown by referring to FIG. 1.
  • a suitable drive means for instance an electric motor 7 which is located at the stationary frame portion 2, as well as a transmission unit 8 equipped with a suitable drive journal or shaft 9.
  • the sealing device incorporates two roller members 10 and 11.
  • these roller members 10 and 11 include for instance a steel core 10a and 11a, respectively, and an elastic covering 10b and 11b respectively, for instance formed of a suitable elastomeric material such as rubber.
  • the roller journals 12 and 13 are rotatably mounted in bearing block means 14.
  • the inventive device incorporates four piston rods 15, each of which carry an associated piston member 16 or 17 which can be acted upon by a suitable pressurized fluid medium, such as air or an appropriate hydraulic medium.
  • a suitable pressurized fluid medium such as air or an appropriate hydraulic medium.
  • each piston rod of the two pistons 16 is attached to a bearing block 18 which, in turn, is operably connected with a respective bearing block 14 at each end of the sealing device, through the agency of two respective associated guide rods 19, as best shown in FIG. 2.
  • the piston rods 15 of the other two piston members 17 are secured to the further bearing blocks 14 which support the roller member 10.
  • the bearing blocks 14. which support the roller member 11 are operably connected via a respective piston rod member 21 with an associated piston member 34.
  • This piston member 34 can be operated by means of a suitable pressurized medium, such as air or hydraulically. As shown in FIG. 2, the piston member 34 can be horizontally reciprocated back and forth in a cylinder 4a provided at the stationary frame portion 4. Thus, the piston member 34 enables the roller member 11 to be moved along the guide rods 19 towards the other roller member 10 or away from the latter.
  • both of the roller members 10 and 11 can be raised and lowered, and by means of the piston member 34, the roller member 11 is only horizontally displaceable.
  • the inventive sealing device is secured to the pressure vessel or container by means of the housing or frame portion 1. Above this frame portion 1 the stationary frame portion 2 is provided with a slit 24. Sealing plate means 25 are placed upon the stationary frame portion 2. Rail-like wearing elements 26 are preferably exchangeably inserted in the sealing plate members 25, although they could also be non-exehangeably inserted therein.
  • rollers 28 and 29 there have been provided two additional rollers 28 and 29. Furthermore, the end faces of the roller members 10 and 11 as well as the rollers 28 and 29 which are situated at one end are sealed by a common plate member 30. As best recognized by referring to FIG. 4, the roller members 10 and 28 as well as the roller members 11 and 29 roll upon one another.
  • additional rollers 28 and 29 sealingly bear against wearing members 26 by means of their outer surface, preferably formed of steel, and such rollers are supported in suitable non-illustrated bearing blocks which can be raised and lowered together with the bearing blocks 14 and 18, in the aforedescribed manner, by means of the piston members 16 and 17.
  • the rail-like, exchangeable insert members 26 can be formed of a rubber-elastic or elastomeric material. Since the outer surface or jacket of the additional rollers 28 and 29 is formed of steel in each instance, only a very slight wear occurs during the sealing sliding motion of the jacket surface at the wearing members or elements 26.
  • FIG. 5 there is shown a variant of the sealing arrangement for the end faces or terminal sides of the roller members 10 and 11.
  • a plate member 31 beams from above upon an associated sealing plate member 25.
  • the plate member 31 can be pressed in sealing fashion against the sealing plate 25 by means of the piston member 32 which is actuated or impinged by a suitable pressurized fluid medium, such as air or a hydraulic medium, and in similar fashion the piston member 33, which is likewise actuated by an appropriate pressurized fluid medium, presses the plate member 31 in sealing fashion against the associated end faces of the roller members 10 and 11.
  • a suitable pressurized fluid medium such as air or a hydraulic medium
  • the yoke 34 is rigidly connected with the bearing block means 14 which supports the roller member 11, so that during horizontal displacement of the roller member 11 by means of its associated piston 34 no relative movement takes place at the sealing surfaces between the plate member 31 and the roller member 11.
  • roller members 10 and 11 are pressed in sealing fashion against the wearing elements 26, and the drive motor 7 drives the roller members 10 and 11 and thus the latter serve to transport or convey the web of material 35.
  • the end sealing plate members 27 (FIGS. 1 to 3) or the plate members 31 (FIG. 5) are likewise pressed in sealing fashion against the end faces of the associated roller members and 11.
  • the pressure which prevails in the pressure vessel or container likewise exists in this triangularshaped hollow compartment 50.
  • This pressure is sealed in the pressure gap between both the roller members 10 and 11 as well as in the pressure gap between the roller members 10 and 11 and their bearing locations defined by the wearing elements 26 as well as between the surface of the plate members 27 or 31 and the associated end faces of these roller members 10, 11.
  • roller members 10 and 11 are spaced from one another through the action of the piston members 16, 17 and 34, so that the sealing surfaces can be cleaned and, if desired, can be replaced.
  • the lowering or raising and the horizontal displacement of the roller members 10 and 11 takes place quite simply by means of the driving components, 5a, 16 and 6a, 17 as well as 4a, 34.
  • any possible lengthwise expansion of the roller members 10 and 11 owing to heat, will be taken up by the plate members 31 which are resiliently pressed by means of the hydraulic or pneumatic fluid medium.
  • the piston means which are actuated hydraulically or pneumatically, it is possible to determine and vary, as desired or required, the sealing pressure in accordance with the internal pressure of the pressure container or vessel. The few sealing elements which are subjected to wear can be easily replaced by others.
  • a sealing device for a web of fabric during its continuous passage through a pressure container comprising frame means, roller means mounted for rotation at said frame means and disposed at opposite sides of the web of fabric, plate means cooperating with the end faces of said roller means, means for bearing with pressure against the outer surface of said roller means, said bearing means including support means fixedly secured with said frame means, said plate means and bearing means acting upon said roller means to seal the latter, pressurized fluid medium actuated piston means for urging said roller means towards said fixedly secured support means, and at least one pressurized fiuid medium actuated piston means for urging said roller means against one another, said pressurized fluid medium actuated piston means serving to space said roller means from said support means.
  • roller means include a pair of roller members which bear directly against said support means.
  • bearing means further include at least two rollers, said roller means including a pair of roller members bearing indirectly against said support means through the agency of said two rollers.
  • a sealing device for a web of fabric as defined in claim 4, further including at least approximately vertical column means along which said pair of roller members are displaceably guided, in order to remove said roller members from contact with said two rollers, at least approximately horizontal column means along which there is displaceably guided at least one of said roller members in order to space both of said roller members from one another.
  • bearing means further including rotatably mounted rollers possessing an outer metallic surface, each said roller means having an outer surface formed of rubber-like material which is pressed in sealing fashion against said rotatably mounted rollers, said support means being substantially rail-like members which are fixedly but detachably secured to said frame means, the outer surface of said rollers being pressable against said raillike members.
