Abstract
Steam blower box for the application of steam onto a paper or cardboard web, the steam blower box connected to a plurality of steam lines. The steam lines are routed to at least one support plate, where the steam lines are each to be attached to a supply line connected to the steam source. The supply lines are equipped with connecting nipples, each having a stop, and the support plate has openings into which the connecting nipples can be inserted from one side of the support plate. The supply lines are locked down to the support plate by at least one retaining strip which works in conjunction with the stops and is movable behind the stops.
Claims30
A steam blower box for the application of steam onto a material web to be dewatered passing through a press section of a paper-making machine, said steam blower box comprising:
- a blower box extending, transverse to a web travel direction of the material web, over an entire width of the material web, said blower box comprising a plurality of zone chambers, arranged side by side over the width of the web, and connected to a plurality of steam lines, said plurality of steam lines to be connected to a corresponding plurality of supply lines connected to a steam source;
- a connecting nipple having a stop provided to each of the supply lines at ends of the supply lines to be connected to the steam lines;
- a support plate to which said plurality of steam lines is routed, said support plate having openings formed therein into which said connecting nipples can be inserted from one side of said support plate until said stops contact said one side of the plate, said steam lines connecting to said openings on a remaining side of the plate;
- and
- at least one retaining strip which works in conjunction with the stops to lock down the supply lines to the support plate, said at least one retaining strip being movable parallel to said support plate behind said stops so that said stops are held on said one side of the plate by said at least one retaining strip.
A steam blower box for the application of steam onto a material web, said steam blower box having a plurality of steam lines to be connected to a corresponding plurality of supply lines connected to a steam source, comprising:
- a support plate having a first and second surface, said support plate having openings formed therein arranged in rows and columns, the number of openings corresponding to the number of steam lines and the number of supply lines, and each of the steam lines being connected to a corresponding opening on the first surface of the support plate;
- a plurality of guide members extending in a direction of said columns of openings, each guide member having a plurality of sliding guides formed therethrough, said plurality of sliding guides of each guide member being aligned along a direction of said rows of openings;
- a connecting nipple provided to each of the supply lines, each said connecting nipple being insertable into said openings from said second surface of said support plate, and each said connecting nipple having a flange stop formed thereon;
- and
- a plurality of retaining strips that hold said flange stops of said connecting nipples against said second surface of said support plate and thereby hold said connecting nipples in said openings from said second surface of said support plate, each retaining strip corresponding to a sliding guide and being slidable in said direction of said rows of openings into said aligned sliding guides through said plurality of guide members.
A method of connecting steam supply lines to rows of openings in a support plate of a steam blower box, comprising:
- inserting a connecting nipple of a steam supply line into an opening in a row of openings until a flange stop of the connecting nipple contacts a surface of the support plate;
- sliding a retaining strip parallel to the row of openings and parallel to the surface of the support plate behind the flange stop to lock the connecting nipple against the support plate;
- inserting a next connecting nipple of a next steam supply line in a next opening in the row of openings until a flange stop of the next connecting nipple contacts the surface of the support plate;
- further sliding the retaining strip behind the flange stop of the next connecting nipple to lock the next connecting nipple against the support plate;
- and
- repeating said inserting a next connecting nipple and said further sliding the retaining strip, in stepwise fashion, until all of the openings in said row of openings are filled with connecting nipples locked against the support plate by the retaining strip.
