Definitions

  • the present invention refers to a method for regulating the clearance angle of paper machine foil and an apparatus used therefor.
  • a foil is the dewatering unit of paper machine's wire section. The dewatering properties and working up the pulp can be efficiently affected by regulating the clearance angle of foil.
  • the third alternative known is a method in which, like in the previous method there are mounting supports on which the foil has been fastened with fulcrum pins.
  • the angle is regulated manually with a threaded spindle or bolt from both ends of the foil individually.
  • Characteristic of the regulating method of the clearance angle of foil according to the invention is that regulating of the clearance angle of the foil is only performed from one side of the paper machine, preferably from only one substantially steplessly functioning regulating element.
  • the apparatuses situated on different sides of the machine have, as an example, been synchronized with a connecting shaft; thus the regulations on different sides of the machine are equal.
  • the clearance angle of the foil can be regulated while the paper machine is running.
  • the regulating apparatus is equipped with eccentric levers in order to abolish clearance and damp vibration.
  • the apparatus is equipped with an articulated shaft and in addition with support screws and bolts to strengthen the structure.
  • the centre of the articulated shaft is situated on the same vertical level with the point of the ceramic wearing piece and in height direction as close as possible to the point of the ceramic wearing piece.
  • the actuator of the lifting appliance is a screw hoist or similar.
  • the operating switches 2 and the angle indicating gauge 3 of the foil 9, situated on the operative side 1 of the regulating apparatus have been presented in figures lA and 1B.
  • the drive motor 5 is situated on the appliance side 4 of the regulating apparatus.
  • the shaft 6 connects the apparatuses situated on different sides of the machine.
  • the foil 9 has been fastened to the body of the paper machine 7 with mounting screws 8.
  • the regulating apparatus of the angle whose hinge support 11 is fastened to the body of the paper machine with screws 12, has been presented in figures 2A, 2B, 3A and 3B.
  • Mounting plates 14 have been welded or otherwise attached to the ends of the foil 9, on which the articulated shaft 15 and a lug 17 that transmits the movement of the screw hoist 16 have been attached.
  • the hinge support 11 has elongated holes 18, which allow the rotational motion of the support screws 19 fastened to the mounting plates 14, during regulation of the foil 9.
  • the clearance between the bolt 20 and the plate 21 attached to the hinge support 11 is regulated from the bolts 20 on the support screws 19.
  • the eccentric lever 22 revolves in relation to the shaft 23 operated by the cylinder 24.
  • Reference number 25 indicates the cover bellow of the screw hoist.
  • the centre of the articulated shaft 15 is situated as close as possible to the ceramic wearing piece 26 and on the same vertical level with its point.
  • Angle regulation of the foil 9 is operated with operating switches 2, from which the clockwise and counter-clockwise rotary movement of the motor is operated.
  • the cylinder 24 pulls the eccentric lever 22 loose from the end plate 14 allowing the rotational motion.
  • the motor 5 stops the cylinder 24 turns the eccentric lever 22 back to the locked position removing the clearances and thus preventing vibration of the foil 9.
  • Position angle of the foil 9, preferably being between 0..-3 degrees, can be observed in the angle indicating gauge 3.
  • Motor can, instead of the fixed motor shown in the drawing, also be a removable hand tool, for example an air-driven or electrical screw wrench or a hand crank.
  • Actuator of the rotational motion of the foil can be a screw hoist, whose stroke is preferably approx. 20 mm. Screw hoists or similar have been synchronized by interlocking them with a connecting shaft or similar.
