Definitions

  • One of the spiral volutes leads the coolant from the inlet connection to the center of the disc and into the other spiral volute whereby the coolant is lead from the center of the disc to the outlet connection.
  • the volutes are separated from each other by walls extending transverse to the major plane of the disc to form a cooling channel.
  • the volutes are separated by a single common wall extending substantially perpendicular to the major plane of the disc and the cross section of the cooling channel may be substantially quadrangular.
  • the volutes are made from spirally interwound open sections welded together.
  • This invention relates to a slide for hot blast slide dampers composed of volutes of spirally interwound sections forming a flat disc peripherally embraced by a ring which projects from the side faces of the disc, and which is provided with'entry and outlet connections for a coolant conducted through the channels formed by the volutes to the center of the disc and then back 1 again.
  • German Pat. Specification No. 1,031,329 to form the cooling channels This is a form of construction which provides excellent cooling effects with a minimum volume of coolant.
  • structurally the arrangement is not yet adequate, without considerable additional reinforcement, to withstand the static loads that arise when the damper is closed at the hot blastpressures that are now conventional.
  • a slide for hot blast slide dampers which affords a cooling channel in the form of a pair of spiral volutes arranged in the shape of a flat disc, one of the spiral volutes leading coolant from an inlet connection at the edge of the disc to the center of the disc and into the other of the spiral volutes, by which the coolant is then lead from the center of the disc to an outlet connection at the edge of the disc, the volutes are separated from each other by walls extending transverse to the major plane of the disc.
  • the volutes are preferably separated by a single common wall extending substantially perpendicular to the major plane of the disc.
  • the crosssection of the cooling channel is thus preferably substantially square or rectangular.
  • the structure may be manufactured in any desired manner but we have found that a method involving welding open channel section material is preferable.
  • the volutes are preferably made from spirally interwound open sections welded together.
  • the slide will be able to stand up to the loads which are imposed by the hot blast pressures and hot blast temperatures that are now conventional, without the need of additional stiffening means.
  • the section moduli of channel sections far exceed those of hollow section spirals of similar weight, bearing in mind that the flanges of channel sections can be made thicker and at the same time the webs made thinner, since in the contemplated application the latter contributes little to the strength of the structure.
  • a slide according to the invention of the same stability and load-bearing ability as a conventional slide can be substantially thinner than the latter, a circumstance which has a favorable effect on the overall length of the slide damper assembly.
  • the invention provides an efficient damper slide which satisfies the technical and service requirements.
  • spiral volutes used for the construction of the proposed slide are wound from a section offering considerable resistance to being bent to the required shape it is preferable to form the center of the spiral volutes from a special core piece whichcontinues the cooling channelsformed by the sections. This considerably facilitates the production of the slide.
  • FIG. 1 is a plan view of one face of a damper slide, a part of the center as well as a portion including the inlet and outlet connections for the coolant being in section,
  • FIG. 2 is a part sectional side view of the slide according to FIG. 1,
  • FIG. 3 is a cross section on a larger scale of the core piece of the damper slide
  • FIG. 4 is a fragmentary cross section of the slide, likewise on a larger scale.
  • 1 and 2 are two flat spiral volutes consisting of steel I-section channel members, the convolutions being radially spaced by the overall width b of the I-section flanges.
  • the two volutes l and 2 are interwound and their flange edges, which are bevelled for the formation of weld seams, are welded together to provide a spiral pitch b.
  • This form of construction defines convoluted cooling channels 5 and 6 between the webs 3 and 4 of consecutive convolutions of the two spiral volutes, the two channels being connected in the center of the slide.
  • One channel 5 serves for conducting the coolant to the slide center, whereas the other channel 6 conducts it back again to the outside.
  • a core piece 7 which contains deflecting means 8 and 9 forming continuations of the webs 3 and 4 of the spirally interwound members 1 and 2 which are connected to the core piece 7 at 10 and 11.
  • the circumference of the slide is embraced by a hollow ring 12 provided with sealing faces at 13 and 14 which cooperate with corresponding sealing faces in the damper casing when the slide damper is closed.
  • the hollow ring 12 On its outer periphery the hollow ring 12 is provided with an entry connection 15 and an outlet connection 16 for the coolant and it forms the intermediate member between the connections 15 and 16 and the volutes 1 and 2, the webs 3 and 4 of the sections merging at 17 and 18 into the inner circumferential wall of the hollow ring 12.
  • the width of the hollow ring 12 exceeds the width of the sections forming the volutes 1 and 2 so that pan-shaped recesses 19 and 20 which remain on each face of the slide can be filled with a refractory material.
  • said pair of channel members being spirally interwound with the edges of the flanges of one of said members sealingly connected to the edges of the flanges of the other of said members;
  • said connected and spirally interwound members forming therebetween a pair of spaced convoluted cooling channels, said channels being separated by said webs of said members;
  • cooling fluid flows into said first channel from said inlet connection, through said first channel to said center of said disc and into said second channel, and through said second channel to said outlet connection;
  • a core member positioned at said center of said disc, said core member having deflecting means forming continuations of said webs of said members.
  • a slide as claimed in claim 1 further comprising a hollow ring surrounding the periphery of said disc, said hollow ring having sealing surfaces for engagement with corresponding surfaces of said casing of said slide damper.
