Definitions

  • the present invention relates to screens for screening mixtures to be used in connection with for example dispersing devices fiber web machines or mineral industry machines. More especially the invention relates to a screen according to the preamble part of claim 1 for screening mixtures.
  • screens are used for screening for example mixtures of pigment slurries, starch etc.
  • mixtures for example pigment slurries and coating pastes are used to coat the web.
  • the mixtures are of different compositions and have different kinds of dry substances i.e. solids and liquid, for example water and they are typically prepared for each specific use.
  • these mixtures are to be screened.
  • the primary screening is done to the mixture as part of the mixture preparing but additionally screens are arranged to coating stations in connection with the mixture feed circulation. The purpose of screening is to separate from the coating mixture dry substance accumulations, fibers detached from the web and other foreign matter that would cause coating defects.
  • screens are used for screening for example mixtures of pigment slurry.
  • sand, flocculated pigment particles and other foreign substances which have to be removed from the slurry.
  • Vibrating flat screens are conventionally used for screening slurries through a flat wire cloth with the help of the hydrostatic pressure imposed by a slurry layer. The vibration keeps the cloth unclogged and improves the screening capacity by decreasing the viscosity of the slurry. Vibrating screens have good selectivity but not so good capacity.
  • Pressure screens are used for screening slurries and pastes in connection with feed circulation. The pressure screen comprises a drum of spiral wires attached apart from each other to create a spiraled slot. Pressure screens have high capacity but not so good selectivity.
  • An object of the present invention is to create a screen in which the problems of the prior art screens are eliminated or at least minimized.
  • a screen to improve selectivity as compared to conventional pressure screens and to combine the advantages of a vibrating screen and a conventional pressure screen is disclosed.
  • the screen for screening filler and pigment slurries and coating mixtures in papermaking has been disclosed, which screen comprises an in-feed chamber having at least a portion of its walls formed by a straining element perforated with holes, elements for feeding the material to be strained into the in-feed chamber, elements for routing the fraction of the material passed through said straining element to further use and elements for discharging the non-passed fraction our from the screen as rejects, and elements for feeding the material to be strained into said in-feed chamber so that the pressure in said in-feed chamber is higher than the pressure in the discharge chamber after said straining element and the straining element employed is a perforated member with a hole size smaller than 300 ⁇ m and in conjunction with the in-feed chamber are adapted means for agitating the material to be strained and for forming a flow pattern in the vicinity of said straining element.
  • This prior art screen fulfills the needs of screening well and provides for good selectivity in combination to high capacity but in some cases its durability is not sufficient and another object of the present invention is to further improve the prior art screen as disclosed in EP patent application publication 0733734 especially in relation to creating better turbulence for the flow.
  • the screen according to the invention is mainly characterized by the features of the characterizing clause of claim 1.
  • the screen is sintered and comprises at least two mesh layers and in the screen mesh element the distance between the rotor element and the screen mesh element is 1 mm - 70 mm.
  • the sintered screen mesh element comprises several sintered mesh layers.
  • the screen mesh element with at least two layers according to the invention has good pressure responsivity, for example to pressures of about 1 bar pressure difference over screen element and more layers are advantageous if further responsivity to pressure is needed.
  • Layers are advantageously formed of mesh structure that creates an open surface of 30 - 80 %, advantageously of 40 -70 %, for the screen mesh element.
  • the material of the screen mesh element is steel advantageously acid-resistant steel is used.
  • the distance between the rotor element that provides for a mixing wing and the screen mesh element is 1 mm - 15 mm.
  • the screen is located substantially vertically such that the screen element extends in substantially vertical direction or in inclination angle greater than 0 but less than 45 degrees and thus the reject is in the lower part.
  • the rotor element is a rotor blade that has been designed such that it generates turbulence on the surface of the screen mesh element.
  • the screen comprises a venting channel by which air is removed from the screening chamber.
  • the screen mesh element comprises at least one support layer for further mechanical strength.
  • the pressure in the screen is higher in inlet side than in outlet side.
  • FIG 1 an example of a screen according to an advantageous feature of the invention is shown.
  • the screen 10 comprises a screening chamber 18 and a discharge chamber 19 that are located on opposite sides of a screen mesh element 20 that thus divides the chamber into two main chambers 18, 19.
  • Mixture to be screened by the screen 10 is fed to the screening chamber 18 via inlet opening 11.
  • the screening chamber 18 the mixture is subject to turbulence provided by the rotor blade 17 with design that crates turbulence on the surface of the screen mesh element 20.
  • the rotor blade 17 is rotated by motor 15 or corresponding actuator via a shaft 16 on which the rotor blade 17 is attached.
  • the chamber of the screen 10 comprising screening chamber 18 and discharge chamber 19 is located vertically or in inclination as shown in the figure 1 so that inlet opening 11 and venting channel 14 are in the upper part of the screening chamber 18 and the outlet opening 12 the reject discharge 13 are in the lower part of the screening chamber 18.
  • the screen mesh element extends in substantially vertical direction or in inclination angle in respect to the vertical direction which angle is greater than 0 but less than 45 degrees.
  • the reject separated by the screen mesh 21 of the screen mesh element 20 accumulates with the help of gravity in the vicinity of the reject discharge 13 located at the substantially lowest section of the screening chamber 18.
  • the screened mixture passed through the screen mesh 21 of the screen mesh element 20 is removed from the discharge chamber 17 via the outlet opening 12.
  • the chamber of the screen 10 has wall structures that limit the chamber space and support the rotor blade 17 and its shaft 16.
  • the screen mesh element 20 is attached inside the chamber walls along its outer circumference thus creating the divider of the chamber.
  • the center of the screen mesh element 20 is attached by a support piece 24 to the chamber wall.
  • the distance between the rotor blade 17 that provides for a mixing wing and the screen mesh element 20 is 1 mm - 70 mm, advantageously 1 mm - 15 mm.
  • the screen mesh element 20 has an outer support structure 22 that circumvents is outer circumference and to inner side of which at least two sintered screen mesh layers 21 are attached and which is attached to the walls of the chamber of the screen 10 at its outer side.
  • a center support structure is attached to which the support piece 24 is attached for supporting the center area of the mesh to the wall of the discharge chamber 18 ( fig. 1 ).
  • the screen mesh 21 is sintered and its material is steel, advantageously acid-resistant steel.
  • the mesh like structure comprises at least two mesh layers and its open surface is 30 - 80 %, advantageously 40 -70 %.
  • the screen mesh element may also comprise support layers for adding mechanical strength.
