  • Patent number: 7673395
    Abstract: A dryer bar apparatus of a dryer for drying a web in a papermaking machine includes a number of turbulence bars circumferentially spaced equidistantly around the inner surface of the dryer shell for generating turbulence within a layer of condensate. The arrangement is such that uniformity of the transfer of thermal energy in the cross machine direction is maximized while the transfer of thermal energy through the dryer shell from the inner to the outer surface is minimized. Also, the number of turbulence bars is determined by the equation: N=int{2?Ri/[4?(Ri/d)½+W]} in which: N=the number of turbulence bars in the dryer shell; int=an integer number of a value in { } brackets; ?=3.1415; Ri=the inside radius of the inner surface of the dryer shell in inches; d=an average depth of the layer in inches; W=a width of each of the turbulence bars in inches.

  • Patent number: 5528838
    Abstract: The invention pertains to apparatus for thermally insulating selected portions of a cylindrical dryer drum, usually adjacent the drum ends, for the purpose of obtaining a substantially uniform drum shell temperature throughout its length to obtain a uniform moisture profile throughout the width of the web being dried. A plurality of cylindrical segments are bolted together within the drum interior to define a circumferential assembly biased against the drum inner surface. The segments each include a thermal insulation material engaging the drum shell preventing direct access of that engaged portion of the shell with the steam within the drum thereby reducing the exterior temperature of the drum shell at the location of the thermally insulated segment. The segments may be bolted together, widthwise, to increase the axial dimension of the temperature controlling segment assembly.

  • Patent number: 5226677
    Abstract: The invention pertains to a rotary joint for use with rotating machinery, such as a dryer drum, where the joint is conveying steam by means of a rotating nipple and sealing structure. The primary elements are a stationary housing comprised of a head, body and a wear plate, a pickup tube and a spring biased nipple with a collar which engages a molybdenum lubricated reverse radius seal ring. Alignment of the components is maintained through the interaction of two guide bearings supporting the nipple, the wear plate sealing surface and the nipple collar which is spring biased against a reverse radius seal ring intermediate the wear plate sealing surface and the nipple collar sealing surface.

  • Patent number: 5169181
    Abstract: A rotary joint for rotating heat exchangers of the drum or roll type having a journal wherein damage to the rotary joint by radial impact forces is minimized by mounting the joint housing upon the rotating journal, the joint nipple is stationary and mounted upon the fluid receiving head and spherical roller bearings are interposed between the housing and nipple. The primary fluid seal is located adjacent the heat exchanger journal and impact forces between the seal components and nipple, and their surrounding structure, is absorbed by the use of annular elastic glide rings which also function as fluid seals.

  • Patent number: 5109612
    Abstract: A low differential pressure rotary syphon for the purpose of removing condensate from the interior of steam a heated dryer drum under low differential pressure conditions. The reduction in the magnitude of differential pressure required to remove the condensate is accomplished through the direct introduction of steam into a central plenum area receiving condensate thereby reducing the mass density of the condensate mixture. The reduction in mass density and the steam introduced acting directly on the condensate within the central plenum area facilitates the removal of the condensate from the drying drum interior.

  • Patent number: 5110162
    Abstract: This invention pertains to a rotary joint for use with rotating machinery where the joint is conveying high temperature corrosive fluids such as molten salts. The joint includes both a stationary head to which external connections are made and a housing mounted on and rotating with a rotary apparatus with which the joint communicates. Alignment of the components is maintained through the interaction of two sleeve bearings disposed between a nipple coaxially extending from the head and the joint housing surrounding the nipple; the sleeve bearings being axially displaced from each other, the primary seal occupying an intermediate position. The primary seal is a spherical seal, interposed between a stationary nipple seal surface and a rotary housing sealing surface. The seal is preloaded by means of an external joint biasing support bracket to reduce leakage under conditions of low internal fluid pressures.

  • Patent number: 5098135
    Abstract: A rotary joint for introducing or removing a heat exchanging medium, such as steam, from a rotary dryer drum characterized by its ability to accommodate significant axial expansion or contraction with respect to the axis of drum rotation. A rod supported housing includes an axially displaceable nipple having an end engaging an annular seal ring associated with a drum journal mounted wear plate. Axial movement between the wear plate and joint housing is accommodated by relative movement between the housing and nipple, and preferably, springs axially bias the nipple into engagement with a self-aligning seal ring to maintain a fluid tight connection under all thermal and pressure conditions.

  • Patent number: 5067824
    Abstract: The invention pertains to the method and apparatus of compensating for the axial bearing load forces imposed upon rotary joints conveying a pressurized fluid medium, such as steam, by imposing an axial force on the rotary joint housing proportional to the pressure within the rotary joint by use of a distinctively different pressurized medium than that comveyed by the joint, such as compressed air. An expansible chamber motor capable of imposing an axial force on the rotary joint utilizes compressed air whose pressure is controlled by a sensing and regulating system responsive to the pressure within the rotary joint.
