Definitions

  • the invention relates to sealing strip holders for sealing strips of suction rolls and their use in suction rolls.
  • a suction roll which is used for dewatering web material, for example in paper machines, has a roll shell provided with openings and at least one suction box inside.
  • the suction box is fixedly mounted inside the suction roll, with the roll shell provided with holes rotating around the suction box.
  • it has sealing strips on the side, which seal the interior of the suction box against the remaining volume of the suction roll, specifically in the longitudinal direction of the suction roll.
  • the suction box In the circumferential direction of the suction roll, the suction box is delimited at both ends by format limiters and sealed against the roll shell.
  • a particular challenge in the construction and operation of suction rolls is the supply of lubricating water to reduce heat generation and wear on the sealing strip.
  • the friction surface of the sealing strip is reduced by the openings of the lubricating water supply
  • the openings of the lubricating water supply are wearing out noticeably
  • the sealing strip which is designed as a wear part, is complex to manufacture and therefore more expensive
  • the holder itself is also more complicated, and fifthly, it is movable in the sealing strip holder
  • Sealing strips as they are customary according to the prior art, the transition from the sealing strip holder to the sealing strip is difficult, which means that the assembly and sealing of the lubricating water system is complex
  • the lubrication groove or the openings in the sealing strip can be closed by impurities, fibers or chemicals , which would cause a local increase in wear and temperature, which in turn can lead to damage to the sealing strip or the roller.
  • the object on which the invention is based is to carry out the introduction of the lubricating water in a simple, space-saving and targeted manner. This object is achieved by the features of claim 1 for a sealing strip holder. This results in uses of the sealing strip holder according to claims 14 and 15.
  • the lubricant supply is to be integrated into the sealing strip holder.
  • the lubricating water can be brought in very close to the friction surface, i.e. the surface with which the sealing strip rubs on the roller shell, and the space requirement can be reduced compared to a spray pipe mounted in front of the sealing strip holder.
  • the amount of lubricant can be reduced by the targeted introduction close to the sealing strip, whereby the otherwise enormous water consumption of the sealing strip is advantageously reduced.
  • a device using a sealing strip holder thus consists of a suction roller, inside of which a suction box is attached which is laterally bounded by sealing strips. At least one sealing strip is assigned a lubricating water supply which, viewed in the running direction, introduces lubricating fluid in front of the sealing strip in the direction of the inside of the perforated casing of the suction roll, the lubricating water supply being integrated into the sealing strip holder.
  • Each sealing strip preferably also has an actuator by means of which the contact pressure of the sealing strip on the inner lateral surface of the suction roll can be changed.
  • the second, rear sealing strip viewed in the running direction preferably additionally has a second actuator by means of which the opening angle of the gap between the sealing strip and the suction roll shell can be changed.
  • the second, rear sealing strip seen in the running direction preferably has an electroacoustic transducer, which is preferably integrated into the holder of the sealing strip and is thus protected from moisture.
  • Temperature sensors are preferably attached in the sealing strips, which, in addition to temperature measurement, preferably also serve to measure wear. Provision is preferably made for the data from the sensors to be processed in a miniserver and the actuators to be controlled by the miniserver.
  • a miniserver is a miniaturized data processing system with input and output modules and options for digital communication, in particular for wireless communication with input and output devices and other data processing systems in a network.
  • a flow sensor is preferably present in the lubricant feed or in the line leading to the lubricant feed, which flow sensor is in data connection with the miniserver in order to monitor or measure the amount of spray water used in real time.
  • the flow rate is preferably regulated or controlled by the mini server, for example by adjusting at least one valve.
  • the temperature of the sealing strip is preferably measured and the use of lubricant or the amount of lubricant is controlled or regulated as a function of the measured temperature.
  • the temperature can be measured at one or more points on the sealing strip and the amount of lubricating water introduced over the length of the sealing strip can be uniformly high in every area of the sealing strip. If the temperature of the sealing strip is measured in several areas of the sealing strip, a local temperature profile can also be recorded in the sealing strip.
  • the amount of lubricant introduced can advantageously be controlled or regulated separately in individual areas of the longitudinal course of the sealing strip, so that in the event of local heat generation in the sealing strip, lubricating water is only introduced in the affected area. Since material adhering to the sealing strip is also washed away by the introduction of lubricating water, it is possible to react to temperature increases caused by such impurities in that the adhering material is washed away by increasing the flow of lubricating water.
  • the temperature sensor inside the sealing strip, as shown in the DE 102007027688 A1 known.
  • the distance between the temperature sensors of the DE 102007027688 A1 to the surface in question must be so high that they are still integrated in the material of the sealing strip until the maximum permissible wear is reached.
  • a plurality of temperature sensors can preferably be integrated in the sealing strip, these temperature sensors being inserted or integrated into the sealing strip at different depths.
  • the temperature sensors can also be used for wear monitoring or measurement. This happens because the temperature sensors break as soon as they are no longer protected by the material of the sealing strip and wear out on the suction roll.
  • a plurality of such temperature sensors attached offset in depth are always combined in one sensor unit, wherein a plurality of such sensor units are preferably attached, distributed over the longitudinal direction of the sealing strip.
  • the lubricating water or the lubricant can actually be water or another liquid, in particular other liquids or additives can be added to the water.
  • Fig. 1 the sealing strip according to the invention 1.1, 2.1 is shown with integrated temperature sensors 6.1.
  • several sensor units 6 are integrated in the sealing strip 1.1, 2.1, each sensor unit 6 having four temperature sensors 6.1.
  • the temperature sensors 6.1 With regard to the upper surface, that is to say the friction or friction surface of the sealing strip 1.1, 2.1, the temperature sensors 6.1 have different distances. The distance between two successive temperature sensors 6.1 is 2 mm, for example.
  • the sensor units consist of a circuit board 6.4, temperature sensors 6.1, a microchip 6.2 with an integrated radio module and a power supply using a battery 6.3.
  • a mini server with a radio module is positioned outside the suction roller and receives the data from the sensor units 6 via radio.
  • the miniserver is preferably connected to a network and the data can be visualized via an output device such as a computer, tablet computer, laptop or mobile phone.
  • the sealing strip 1.1, 2.1 has at least one sensor unit 6, preferably the sealing strip 1.1, 2.1 has several sensor units 6 in order to be able to measure the temperature at several points on the sealing strip 1.1, 2.1.
  • a sealing strip system 1 according to the invention is shown, which is preferably used as the first sealing strip system 1 of a suction box 4, viewed in the direction of movement of the roller jacket 3.
  • the sealing strip system 1 consists of a sealing strip 1.1 which is movably received in the groove of the sealing strip holder 1.2.
  • an adjusting hose 1.3 designed as a pressure hose.
  • the sealing strip holder 1.2 In front of the sealing strip 1.1, the sealing strip holder 1.2 is provided with a lubricating water system which has spray nozzles 1.4 via which the lubricating water is introduced through a spray pipe 1.5 preferably integrated in the sealing strip holder 1.2.
  • At least one sensor unit 6 is preferably integrated or inserted into the sealing strip 1.1.
  • the contact pressure with which the sealing strip 1.1 is pressed against the inside of the roll shell 3 can be changed via the pressure in the contact hose 1.3.
  • a sealing strip system 2 according to the invention is shown, which is preferably used as a second sealing strip system 2 of a suction box 4, viewed in the direction of movement of the suction roll.
  • the sealing strip system 2 consists of a sealing strip 2.1 which has a web along the lower front edge which is movably received in the groove of the sealing strip holder 2.2.
  • An adjusting hose 2.3 is located in the groove below the web of the sealing strip 2.1.
  • the sealing strip holder 2.2 is provided with a lubricating water system which has spray nozzles 2.4 via which the lubricating water is introduced through a spray pipe 2.5 which is preferably integrated in the sealing strip holder 2.2.
  • At least one sensor unit 6 is preferably integrated or inserted into the sealing strip 2.1.
  • the contact pressure with which the sealing strip 2.1 is pressed in the front area against the inside of the roll shell 3 can be changed via the pressure in the contact hose 2.3.
  • the sealing strip 2.1 has a curved upper surface, so that the upper surface rests against the roll shell 3 in its front area and in the rear area with the roll shell 3 forms a gradually increasing gap.
  • the width of this gap can be adjusted by a height-adjustable strip 2.7, which can move the rear end of the sealing strip 2.1 closer to the roll shell 3 or away from it.
  • the height-adjustable strip 2.7 is guided along an upwardly sloping groove of a strip 2.6 which can be displaced in the longitudinal direction of the sealing strip 2.1.
  • the displaceable strip 2.6 can be designed as a slide which is displaced in the groove of the sealing strip holder 2.2 by an adjusting spindle driven by the motor.
  • a longitudinal displacement of the displaceable bar 2.6 leads to the height-adjustable bar 2.7 being displaced upwards along the groove. It is also conceivable to make the bar 2.6 stationary and to adjust the height of the height-adjustable bar 2.7 along the groove by longitudinally displacing it. Since there are many possibilities to convert the rotational movement of a stepping motor into a linear movement of an actuator, it should be generally stated that the distance of the rear end of the sealing strip 2.1 to the roll shell 3 can be changed by a motor and can be kept in the respective position.
  • a symbolically represented sound sensor 7 or a pickup is preferably attached, which is used to measure the noise level on or after the sealing strip 2.1.

  • the contact pressure can be regulated by a controllable holding torque of the motor, or it can be regulated indirectly by a resilient element which is located between the actuating element and the sealing strip.
  • the sealing strip is already in contact with the roll shell, a further adjustment of the actuator via the resilient element can exert an increasing force with increasing deformation of the resilient element, with which the sealing strip is pressed against the roll shell.
