Definitions

  • the invention relates to sealing strip systems for 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 size limiters and sealed off from the roll shell.
  • a sealing strip is known which is pressed by a loading element in the form of a pressure hose against the inner wall of the suction roll as long as the vacuum is built up in the suction box.
  • the sealing strip is moved slightly away from the inner wall of the suction roll by a restoring element, also in the form of a pressure hose, so that a defined, adjustable sealing gap results.
  • a restoring element also in the form of a pressure hose
  • the EP 1344865 B1 shows a suction roll in which the inside of the suction roll in the area behind the rear sealing strip of the A microphone is attached to the suction box. If the measured sound level exceeds a limit value, countermeasures are initiated, which can consist of changing the distance between the sealing strip and the inner wall and / or changing the opening angle of the gap between the suction strip and the inner wall.
  • the disadvantage is that it can happen that a stable operating state occurs only slowly or not at all, or that if a threshold value cannot be reached without violating the second threshold value, no suitable countermeasures can be taken.
  • the distance between the temperature sensors of the DE 102007027688 A1 the surface of the sealing strip facing the roll shell must be so high that it is still integrated in the material of the sealing strip until the maximum permissible wear is reached.
  • the object of the present invention is an improved arrangement of the temperature sensors in the interior of the sealing strip. This results in a use for the optimized dewatering of web material.
  • a sealing strip system according to claim 1 and a use according to claim 12 are proposed.
  • the temperature sensors are integrated into the sealing strip, these temperature sensors being inserted or integrated into the sealing strip at different depths. It is particularly advantageous that 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 which are attached offset from one another in depth, are always combined in a sensor unit, with a plurality of such sensor units preferably being attached, distributed over the longitudinal direction of the sealing strip.
  • a plurality of such sensor units preferably being attached, distributed over the longitudinal direction of the sealing strip.
  • a device in which the sealing strip system according to the invention can be used consists of a suction roll, in the inside of which a suction box is attached, which is laterally limited by sealing strips.
  • Each sealing strip is preferably 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.
  • Each sealing strip preferably has at least one 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, seen 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, has an electroacoustic transducer, which is preferably integrated into the holder of the sealing strip and is thus protected from moisture. 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.
  • the temperature of the sealing strip is preferably measured for the optimized use of lubricating liquid and the use of lubricating water or the amount of lubricating water 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.
  • 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.
  • the preferred regulation means that the contact pressure of the sealing strip is regulated to this minimum, which is necessary in order to maintain the vacuum at a specified / specifiable level.
  • the minimum wear required for the respective vacuum or the minimum wear that can be achieved for the respective other operating parameters of the suction roll occurs, since the wear depends on the friction and thus on the contact pressure. If this minimum wear that can be achieved is too high for any reason such as unfavorable operating parameters, contamination or a malfunction, the friction is reduced through the use of lubricating water.
  • An additional benefit of the lubricating water is that dirt such as paper fibers can be removed from the sealing strip.
  • the spray tube is preferably 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.
  • a flow sensor is preferably present in the spray pipe or in the line leading to the spray pipe, which is in data connection with the mini server in order to monitor the amount of spray water used in real time. The flow rate is regulated or controlled by the miniserver, for example by adjusting a valve.
  • a preferred aspect relates to minimizing the noise level caused on the sealing strip.
  • the sometimes very loud noise occurs when the jacket of the suction roll coming from the vacuum in the suction box, passes the second sealing strip and the vacuum in the openings in the roll jacket suddenly collapses.
  • This sudden ventilation is counteracted according to the prior art in that the noise is reduced by gradually opening the gap between the sealing strip and the jacket of the suction roll.
  • From the EP 1344865 B1 it is known to monitor the noise level and to take countermeasures if a threshold value is exceeded. It is preferable to measure the noise level and to regulate it to a minimum by adjusting the opening angle of the gap. The advantage of this is that the lowest possible noise level for the respective operating parameters is achieved in this way.
  • a preferred adjustment mechanism for the opening angle of the gap is based on the EP 1348805 B1 Proposed to achieve the adjustment of the position of the rear end of the sealing strip not via a pressure hose, but by a motor, in particular a stepper motor or servo motor, which serves a bar, which has at least one inclined surface and is arranged below the sealing strip, in the longitudinal direction to move the sealing strip so that the height of the sealing strip can be adjusted along the inclined surface.
  • a motor in particular a stepper motor or servo motor, which serves a bar, which has at least one inclined surface and is arranged below the sealing strip, in the longitudinal direction to move the sealing strip so that the height of the sealing strip can be adjusted along the inclined surface.
  • the gap can be adjusted very precisely via the motor and there is no need for clamping elements and / or stops, as are required for a pressure hose design.
  • This preferred adjustment mechanism is therefore simpler and more exact compared to the prior art, using the position information of the stepper motor, the position of the rear end of
  • the preferred combined control method for all sub-areas includes measuring the temperature in the sealing strips, measuring the vacuum in the suction box, measuring the sound level after the second sealing strip, regulating the contact pressure of the sealing strips, regulating the amount of lubricating water and regulating the opening angle of the second sealing strip, with the contact pressure being the Sealing strips is regulated to the minimum value that is necessary to keep the vacuum in the suction box at a predefinable value, the amount of lubricating water per sealing strip is regulated depending on the temperature of the sealing strip and the opening angle of the second sealing strip is regulated in order to keep the sound level to a minimum .
  • 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 consecutive 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 roll 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 preferably conveyed through Spray tube 1.5 integrated into the sealing strip holder 1.2 is introduced.
  • 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 region and forms a gradually increasing gap with the roll shell 3 in the rear region.
  • 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.
  • One 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 fixed 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 from 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 preferred regulation method provides that the opening angle of the gap between the sealing strip 2.1 and the roll shell 3 is regulated in such a way that the noise level is reduced to a minimum.
  • the sealing strip 1.1 and the front area of the sealing strip 2.1 are preferably also possible to provide an adjustment mechanism for adjusting the sealing strip 1.1 and the front area of the sealing strip 2.1, as is used in the rear area of the sealing strip 2.1. There is no need to use an adjusting hose. Since, in contrast to the rear area of the sealing strip 2.1, the front area and the Sealing strip 1.1 can be brought into contact with the roll shell 3, it is necessary to make the contact pressure controllable or regulatable.
  • 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. It is advantageous that the actuator can also be positioned in such a way that there is a narrow gap between the sealing strip and the roll shell.
