Definitions

  • the invention relates to a tensioning wave, according to the preamble of claim 1 and the WO 2005/123 278 ,
  • the above-mentioned document now proposes to bulge the usually provided on the transverse bars or integrally formed with them pad carrier in the edge region of the screen by about 45 ° to create a trough formed by the screen lining.
  • the lining carrier In the field of solid screen bars is provided to connect the lining carrier via a strut firmly, but at a small distance, with the frame.
  • the lining carriers In the field of movable screen bars, the lining carriers are supported on the cross bar and end at a distance from the frame. Over the entire length of the side seal thus formed a fixed to the frame, the narrow, partially open edge region overlapping lip is provided, which rests elastically on the edge region of the Siebbelages.
  • the lining carrier is provided that they are bent at least 45 °, preferably by 80 ° and particularly preferably by 90 °. By reducing the deflection, a widening of the flat screen surface is achieved with the same wire width, although the articulation of the ends of the lining carrier is more complex on the screen frame.
  • the lining carriers mounted on movable cross members are tapered in their cross section in a region of their bent portion which preferably has both a distance from the free end and a distance from the rectilinear portion and / or a softer material such that they are more flexible than in FIGS other sections, so that the elastic deformation occurs concentrated in this area. This facilitates the control of the vibratory load and reduces the introduction of resulting forces into the cheeks of the screen frame.
  • the screen covering is connected over the entire length with the lateral cheek of the screen frame and covered by a cover strip in the upper end, preferably fixed clamped. This achieves a complete seal.
  • a sieve 1 is alternately provided with transverse bars 3 fixed in the sieve frame 2 and transverse bars 4 movable thereto.
  • the cross bars have on their upper sides pad carrier 6, which according to the invention in their lateral end regions 7 (FIG. Fig. 2 ) are bent, bent in the illustrated embodiment by 90 °.
  • the lining carrier touch with their outer - the bent-up surfaces - the side cheeks 5 of the screen frame 2 on the inside.
  • the lateral, curved, end regions 7 have a very small radius ⁇ 150 mm, which in turn ensures a maximum usable wire width.
  • the Fig. 3 shows in the direction parallel to Siebraum 11 one end of an inventively designed pad carrier 6 in the assembled state:
  • the pad carrier 6 is fixed with its middle, rectilinear part on the transverse bar 4, this includes a bent by 90 ° part 7, whose cross section, indicated by the two inclined edges 12, is formed over almost the entire curved portion 7 tapers (as the minor figures to Fig. 2 show) and is in the end region 7 ', where the course of the lining carrier 6 has already reached the vertical (to be more precise: the normal direction to the screen surface) again formed with full cross section and rectilinear.
  • the lining carrier 6 is modular and consists of said individual parts that are positioned to match each other and connected to each other.
  • the lining carrier may also be formed in one piece.
  • the Endtangenten the pad carrier 6 in this section are as vertical as the screen frame 2 and the side cheek 5, a logical consequence of the curvature by 90 °. If a smaller angle of curvature is selected, it is advantageous to bend the side cheek 5 in the end region of the lining carrier such that it in turn runs parallel to the end tangent of the lining carrier. In this way, the mechanical stability of the connection is increased and facilitates the attachment.
  • Softer material can be used than for the end region 7 'and the middle, rectilinear part.
  • the uppermost region 7 'of the lining carrier 6 is fastened with two screws 8 shown only schematically on the side cheek 5 of the screen frame 2, while the lower, in the figure horizontally and rectilinearly extending area is fixed to the movable cross bar 4, and thus with respect to the screen frame second performs a rotary and / or linear movement.
  • the resulting according to this construction elastic deformation of the lining carrier 6 is due to the reduced cross-section and / or softer material in the curved portion 7 to endure, the Siebbelag 9, indicated by the innermost three lines, according to its nature as a covering of a clamping wave straightener from the home capable of doing so.
  • an additional cover 10 is provided, which contacts the screen lining 9 or the lining carrier 6 in the uppermost region in the illustrated embodiment. Since there are no relative movements between the screen lining 9 and the lining carrier 6 on the one hand and the screen frame 2 take more, this, preferably over the entire Siebin continuous sealing very reliable and tight.
  • the Fig. 4 shows in perspective view a lining carrier 6 together with its inner life in dashed lines.
  • the reduction of the cross section, especially in Siebraum 11 is well seen by the bevel behind the lines 12, from which the taper.
  • the interacting parameters radius of curvature of the bent parts 7, angle of curvature, forming the cross section of the bent parts 7 and selection of the material for this area in respect of the screen to be designed to match.
  • the pad carrier of the fixed, but also the movable, cross bars can be formed without tapering of the cross section, the attachment of the ends 7 'on the screen frame 2 can be done differently than shown, the cover 10 can be designed differently, and much more.
  • a curvature of 90 ° is advantageous, but not necessary in the final consequence. 80-85 ° are enough in many cases.
  • the cross-sectional taper in section 7 is preferably associated with the lack of reinforcement; the radius of curvature, which is preferably made as small as possible so as to disturb the effective screen area as little as possible, may be selected differently than shown.
