Definitions

  • the invention relates to a method and a device for the continuous production of mineral wool nonwovens from rock wool in particular according to the preambles of claims 1 and 2 and to a method for the continuous production of felt webs composed of several mineral wool nonwovens according to claims 17 or 18.
  • a fiber / gas / air mixture produced by a defibration unit for separating the fibers is introduced into a box-like so-called chute, which usually has at the bottom a collecting conveyor which acts as a type of filter belt and which is generally in the form of a gas-permeable rotating one flat conveyor belt is formed. Under the conveyor belt there is a suction device that generates a certain vacuum.
  • the fiber / gas / air mixture - which can also contain a binder - hits the collecting conveyor, the gas / air mixture is suctioned off below the collecting conveyor, which acts as a filter, and the fibers lay thereon Fleece from.
  • a chute with several fiberization units arranged one behind the other is used in order to obtain mineral wool fleeces which have higher wool overlays compared to the former device, i. H. have higher basis weights
  • the partial fleece already formed in the previous defibration unit represents an additional flow resistance in connection with the subsequent partial fleece for the extraction of the gas / air mixture.
  • the fleece formation is often not homogeneous, so that different grammages can arise distributed over the entire surface of the fleece.
  • such devices with a plurality of defibration units have the disadvantage that if a mineral wool fleece with a relatively high basis weight is to be produced, some defibration units may have to be switched off as soon as the capacity of the suction device, i. H. whose fan power is exceeded to keep the chute working.
  • the present invention seeks to remedy this. It is based on the task of proposing a method and a device with which it is possible to continuously produce mineral wool nonwovens, preferably of rock wool, with bulk densities even below 25 kg / m3 in good product quality, and which also achieves a reduction in the energy expenditure for the suction ; further specify methods with which a continuous production of multilayer felt webs from the mineral wool nonwovens formed low bulk density is perfectly possible.
  • suction surface A f ( ⁇ ) , where ⁇ represents the drag coefficient of the respective mineral wool fleece and is mainly dependent on its basis weight and fiber fineness.
  • ⁇ p ⁇ ⁇ 2nd w2
  • ⁇ density of the gas / air mixture (kg / m3)
  • w flow velocity (m / s).
  • suction surface used in this context should be understood so that the individual suction zones are not structurally divided by transverse walls as in the prior art. Rather, these arise due to the vertical projection of the z.
  • an increasing suction surface is available for each free-jet projection surface in the conveying direction, which on the one hand advantageously makes it possible to keep the suction pressure constant in the collecting conveyor unit and to work overall with a lower suction power.
  • the latter measures in turn enable a lower wool overlay per unit area and thus the production of mineral wool nonwovens with relatively low bulk densities.
  • DE-OS 21 22 039 discloses a device for the production of a wool fleece, in which the fibers coming from a defibration unit also hit a curved suction surface, in the form of a high-speed (45 m / sec.) rotating suction drum, but here the actual fleece formation does not take place on the suction drum, since this has too high a peripheral speed, but in a downstream funnel-shaped so-called distributor, which has the same width as the suction drum.
  • Such known suction drums which are also used in the area of the nozzle blowing process, should have a peripheral speed which more or less corresponds to the speed of the fibers produced, they do not serve to deposit the actual nonwoven fabric, but only to suction off the gas / air mixture.
  • This DE-OS 21 22 039 also shows a chute with several defibration units and two suction drums rotating in opposite directions. In this case, however, only fibering units arranged one behind the other are intended, the center lines of which lie in a vertical plane, to which the two suction drums are in turn arranged symmetrically, and these operate on the same principle as the single suction drum described initially.
  • Such a sealing guide element is in any case necessary in order to prevent air and fibers from escaping from the chute that are not intended.
  • the latter also applies to the discharge gap of the wool fleece, because here the sealing must be done by the wool fleece itself.
  • the sealing effect of the fleece is determined by its density, its resilience and the cohesive force of the fleece itself, so that, for. B. a fleece with long elastic single fibers is better able to fill a discharge gap than a fleece with shorter individual fibers with the same gap width.
  • the discharge gap cannot be chosen to be as narrow as desired too high a pre-compression would result for higher basis weights. It can therefore be expedient according to claim 4 that the clear distance between the guide element and the collecting conveyor unit is made adjustable.
  • this double unit has at least three fiberization units assigned to it, symmetrically with the third fiberization unit in the middle between the double unit.
  • the width of the gap provided between the collecting conveyor units for discharging the fleece can be changed.
  • this adjustable element advantageously a drivable roller or a drivable Conveyor belt can be. Two drivable rollers or conveyor belts arranged at a variable distance from one another can also be used for this purpose.
  • each collecting conveyor unit in particular in the area of the gap provided for discharging the fleece, are adjustable in size; further that, according to claim 12, a blow-off device is provided at least in front of a downstream element, by means of which the nonwovens which are formed can be manipulated.
  • the device according to the invention according to claims 2 to 12 offers the main advantage that relatively thin, perforated for the storage surfaces of the collecting conveyor Sheets can be used because they do not have to absorb high surface loads; that is, furthermore, that otherwise statically necessary transverse ribs with a corresponding overall height can be dispensed with, whereby smooth collecting conveyor surfaces are obtained on both sides, which can be kept clean mechanically.
  • This can advantageously be achieved by combining at least one elastic roller-shaped brush that combs the perforation of a collecting conveyor from the inside with its same peripheral speed and at least one further roller-shaped brush that cleans the outer surface with a significantly higher peripheral speed compared to the collecting conveyor.
  • Dry operation of the device according to the invention is thus advantageously possible, which brings significant procedural and cost advantages compared to the prior art, since there are generally complex wet / drying cleaning devices to be used to perforate the collecting conveyors of any adhering fiber. and binder residues.
  • the device according to the invention is particularly suitable according to claim 13 for the production of nonwovens from rock wool, which is produced by the nozzle blowing process.
  • the nozzle blowing process is characterized in that melt flows emerge from a crucible containing a mineral melt under the effect of gravity, which are defibrated in a drawing nozzle under the action of gases flowing parallel to the melt flows at high flow rates, extracted and cooled to below the softening temperature .
  • a rotationally symmetrical unit is selected as the collecting conveyor, i. That is, according to claim 15, at least one collecting conveyor unit is designed as a drum, wherein according to claim 16, the suction pressure in each collecting conveyor unit should be adjustable for itself, so that one can easily adapt to different operating conditions.
  • the second subtask of the present invention is advantageously achieved according to claim 17 by a method in which for the continuous production of a felt web composed of several individual nonwovens, the individual nonwovens coming from several devices according to the invention are deposited together on a running conveyor belt to form a felt web.
  • two fiberizing units 1 and 2 which operate according to the jet-blowing method, generate approximately wedge-shaped free-jet bundles 3 and 4 in their geometry, which consist of a fiber / gas / air / binder mixture, and which consist of one box-shaped drop shaft 5 are surrounded.
  • the lower end of the chute 5 is formed by a collecting conveyor unit 6, which has two curved suction surfaces labeled "a" and "b", on which the shredding units 1, Lay down 2 coming fibers to a wool fleece 7.
  • the collecting conveyor unit 6 has a circumferential perforated conveyor belt 8, which is driven by a motor in the direction of arrow 9, the conveying direction (not shown in the drawing).
  • a suction device is provided within the collecting conveyor unit 6, the suction pressure of which is only effective in a suction chamber 11 arranged below the curved suction surfaces "a" and "b".
  • a guide element 13 in the form of a sheet metal, which delimits a so-called discharge gap 12 and seals against the chute 5, which in the present case is arranged to be stationary.
  • the wedge-shaped geometry of the fiber-free beam bundles 3, 4 is ideally shown in FIG. 1, although certain turbulence has occurred in the chute in previous practice.
  • the respective static pressures must also be distributed in the range up to approx. 10 cm above the nonwoven that forms. For example, pressures of approx. 40 mm / WS against the atmosphere and cross currents of approx. 30 m / sec.
  • the discharge gap is sealed in a defined manner, namely in the present case the discharge gap 12 is sealed by the overall fleece 7.
  • a corresponding collecting conveyor unit is provided instead of the guide plate 13 as a mirror image of the collecting conveyor unit 6 shown in FIG. 1.
  • FIG. 2 is a simplified schematic section through a second embodiment of a device according to the invention, namely with four defibration units 14 to 17, a chute 18 and two oppositely driven collecting conveyors 19 and 21 in the form of drums and a downstream, according to the arrow 20 adjustable sealing roller 22 shown.
  • a total nonwoven 25 is continuously produced from two partial nonwovens 23 and 24, the drum-like collecting conveyors 19, 21 being arranged at a fixed center distance from one another. Since the clear distance between the two collecting conveyors 19, 21 is therefore also constant, the roller 22 virtually assumes the function of an adjustable sealing device at the discharge gap designated by 26.
  • suction surface at the beginning of the formation of the partial fleece 23, designated “c” is smaller than the suction surface designated “d” in the region of the higher fiber support of the partial fleece 23.
  • suction surfaces "c” and “ d” can be set variably, in particular in the area of the discharge gap 26, in order to achieve optimum To be able to maintain discharge and suction conditions.
  • This adjustability is done by a z. B. provided inside the drum 19 stator 27, with which one can separate the suctioned and non-suctioned part of the drum. The aim is that the two nonwovens 23 and 24 are brought together before the discharge.
  • the collecting conveyor 21 is constructed similarly to the collecting conveyor 19, ie it also has a stator 28 with which the suctioned and non-suctioned part is separated from one another. Only the suctioned part ends earlier here than in the opposite collecting conveyor 19, since the partial fleece 24 has to lift off earlier from the collecting conveyor 21 due to the sealing roller 22. This lifting can also be made considerably easier by a blow-off device 30, which is shown schematically in FIG. 2.
  • a third embodiment is also shown schematically simplified with two drum-like collecting conveyors 29 and 31, with which partial nonwovens 32 and 33 are formed.
  • this device for the continuous production of a mineral wool fleece 34 differs only in that it is formed by twin rolls 35 and 36 connected downstream in the conveying direction, the latter being adjustable, which is indicated by the arrows 37 and 38.
  • the twin rollers can be arranged symmetrically but also asymmetrically to the collecting conveyors 29, 31 as shown in FIG. 3.
  • each collecting conveyor 29 or 31 has an inner stator 39 or 41 with which the suctioned or non-suctioned parts of the collecting conveyor can be adjusted.
  • the total suction area is the same for both collecting conveyors 29, 31, the available suction areas for the individual defibration units, designated by "e" and "f", increase again in the conveying direction.
  • FIG. 4 In the case of a continuous production of a felt web 44 composed of a plurality of individual nonwovens 42 and 43, two devices arranged one behind the other according to FIG. 3 are shown in FIG. 4, but each here as a fourth exemplary embodiment with two conveyor belts 45 to instead of the rollers 35, 36 48 are equipped, the distance between them can be changed.
  • the conveyor belts 45 to 48 assume a certain guidance of the individual nonwovens. From FIG. 4 it can be clearly seen how the individual fleece 42 is first placed on a running production belt 49 and then the individual fleece 43 is later placed on this single fleece 42, so that the entire fleece 44 is formed.
  • This example can, of course, be extended to include additional individual fleeces as a support.
  • FIG. 5 schematically shows a detail from a production line with which a felt web 52 composed of a plurality of nonwoven layers 51 is continuously produced.
  • the individual fleece layers 51 come from a single fleece 53, the z. B. has been produced corresponding to the single fleece 42 in Fig. 4.
  • the conveyor belts 54 and 55 arranged here at a variable distance from one another correspond to the conveyor belts 45 and 46 in FIG. 4, whereas in this fifth exemplary embodiment the conveyor belts 54 and 55 can perform an oscillating movement in order to pull the individual fleece 53 on a rotating production belt 56 to be able to deposit the multilayer felt web 52.
  • the mechanism that causes the conveyor belts 54 and 55 to oscillate is not shown in the drawing; rather, it is only symbolically indicated by the double arrow 57.
  • the collecting conveyors of all five exemplary embodiments are each equipped with their own controllable suction system or, in the case of a common suction system, with a corresponding throttle element, specifically in order to be able to react to possibly stationary defibration units and different suction requirements. Furthermore, it is also possible for a collecting conveyor to be acted on by more than two defibration units, since the concept according to the invention advantageously allows work with relatively high fiber loads with a relatively low suction energy.
