Definitions

  • the invention relates to the formation of felts formed from mineral fibers and designated under the generic names of glass wool, rock wool, etc.
  • the mineral fiber felts are constituted continuously by depositing on a conveyor the fibers which are conveyed by gaseous currents.
  • the conveyor retains the fibers and lets the gases through.
  • the fibers Before they are deposited on the conveyor, the fibers are coated with a composition applied in liquid form and intended to bind the fibers together, so as to give cohesion to the felt subsequently constituted.
  • the composition is then crosslinked by a heat treatment performed on the felt which has been previously brought back to the conditions of desired thickness and density.
  • This structure of the felts is favorable to their insulating properties and also to their tensile strength in the longitudinal direction. For many uses such a structure is therefore advantageous. However, understands that such a structure is not the most suitable when for example the product must withstand compression or tearing in the direction of its thickness.
  • one solution is to increase their density by increasing the mass of fibers per unit area on the receiving member where the felt is formed.
  • the accumulation of fibers on the receiving member quickly opposes the passage of gases, and therefore the pursuit in good conditions of the formation of the felt, this does not make it possible to improve other properties such as tear resistance.
  • the direction of the fibers oriented in the direction of the thickness of the felt thus formed substantially improves the resistance to compression and tearing.
  • This structure is disadvantageous with respect to longitudinal tensile strength - felt tends to unfold - or bending.
  • the arrangement of the fibers in the thickness can also result from the assembly of strips of felt whose width corresponds to the thickness of the desired felt, each band being arranged so that the fibers are in planes perpendicular to the faces of the felt constituted .
  • the strips are held against each other by means of a covering or a veil covering one or both sides of the felt.
  • the strips can also be glued directly to each other by their surfaces in contact.
  • Felts produced using this relatively complex technique are mainly used for pipe insulation large diameters.
  • the bending ability and even the winding of the product obtained instead of constituting a disadvantage is particularly sought after.
  • the object of this prior invention is to provide felts in which the mechanical properties, in particular the resistance to compression and tearing in the direction of the thickness of the product, are improved without causing the disadvantages previously encountered, and consequently without forming folds, or assembling bands of felts; the mechanical and insulating properties of said felts remaining otherwise satisfactory.
  • the felt is subjected to at least one longitudinal compression operation, and preferably to two operations of this type.
  • a problem related to such fabrications lies in the homogeneity of the final felt and in particular in its surface homogeneity. In fact, cracks, rupture primers and / or localized swellings are observed on the surface; as many negative defects in terms of mechanical strength, thermal not to mention the unsightly appearance of the whole.
  • This problem is essentially created in the area between the conveyor belts and the reticulation oven.
  • the present invention advantageously consists in a reliable solution, simple and that perfectly solves the problem mentioned above.
  • the subject of the present invention is a set of manufacturing of felt made of crosslinked mineral fiber fibers comprising at least one pair of conveyors formed of a lower conveyor and an upper conveyor arranged in facing relation and intended to compress said felt in at least one direction, a heat treatment means of the felt after passing through the conveyors.
  • the assembly further comprises at least one means disposed between the conveyors and the heat treatment means, intended to prevent the decompression of the felt in this zone, as well as any mechanical interference, said means comprising at least one profile cam adapted to maintain substantially constant and minimal the distance between the conveyors and the heat treatment means; at least one of the conveyors is rigidly connected to an element of the heat treatment means.
  • At least one of the conveyors is held in abutment against said cam by means such as cylinders.
  • the cam is rigidly connected to an element of the heat treatment means, said element being movable vertically and / or horizontally. Horizontal displacement compensates for thermal expansion.
  • the lower conveyor is rigidly connected to an element of the heat treatment means by means of a connecting means.
  • said cam has a curve portion of curvature substantially identical to that of a wheel of the heat treatment means, placed vis-a-vis.
  • the cam further has a straight portion disposed vertically below the curved portion and serves as support for the upper conveyor.
  • the upper conveyor, the cam and the element of the heat treatment means to which it is connected are movable vertically in order to be able to manufacture felts of different thicknesses.
  • the invention furthermore relates to a method for producing felts made of glued fibers, made of mineral material, notably comprising compressing the fibers in at least one direction and then heat-treat the felts to stabilize them.
  • the method further comprises preventing the decompression of the felt between the compression step and the heat treatment step, by means of a profile cam adapted to maintain substantially constant and minimal the distance between the compression means and heat treatment means.
  • the compression means are held in abutment against said cam.
  • the present invention advantageously allows the manufacture of felts with a thickness of between 10 and 500 mm.
  • the minimum distance between the compression means and the inlet of the oven is of the order of 5 mm.
  • the figure 1 describes the global context in which the present invention may advantageously be implemented.
  • FIG. 1 This figure schematically shows a manufacturing line of felts 6 formed of mineral fibers also called rock wool or glass wool.
  • a manufacturing line comprises one or more centrifugation devices 1 for forming fibers 2 which are projected from the centrifugation device (s) 1 into a receiving chamber 3 at the base of which is disposed a conveyor 4 on which fall the fibers.
  • one or more caissons 5 under vacuum are located under the conveyor 4 in order to suck up and pile up the fibers on the conveyor 4.
  • a carpet or felt 6 is thus formed; it is taken out of the chamber 3 between two conveyors 7, 8 for compressing it according to its thickness.
  • the felt 6 is compressed longitudinally by passing between pairs of upstream conveyors 9, 10 and downstream 11, 12 whose speeds are such that the speed of a pair 11, 12 is less than the speed of the upstream pair 9, 10 (relative to the movement of the felt 6 through the conveyors).
  • the felt 6 is directly introduced into an oven 13 where a heat treatment ensures the crosslinking of the binder and the stabilization of the product.
  • a heat treatment ensures the crosslinking of the binder and the stabilization of the product.
  • Other heat treatments may be envisaged without departing from the scope of the present invention.
  • the felt can be cut, conditioned according to the intended uses.
  • the problem at the origin of the invention lies at the outlet of the downstream conveyors 11, 12, before the introduction of the felt 6 in the oven 13.
  • the felt 6 is highly compressed, its density is commonly of the order of 100 kg / m 3 , so that it has a tendency to escape in the gap left free between the downstream conveyors , 11, 12 and the oven 13.
  • the present invention illustrated in more detail on the figure 2 , solves in a new, inventive and unexpected way such a problem.
  • the oven 13 is symbolically limited by dots.
  • a means 14 for preventing the decompression of the felt 6 in this area comprising at least one cam whose profile is adapted to maintain constant and minimal the distance between the conveyors 11, 12 and the oven 13.
  • the upper conveyor 12 is held in abutment against the cam 14 for example by cylinders (not shown) themselves actuated by one or more motors (not shown).
  • This arrangement makes it possible to absorb a dilation of the different elements.
  • the cylinders also make it possible to maintain the conveyor chain tensioned whatever the position of operation.
  • the upper conveyor 12 is vertically movable making it possible to manufacture different thicknesses of felt 6.
  • the cam 14 is preferably rigidly connected to a fixed element of the oven (not shown), which can however be moved vertically, depending on the thickness of the felt to be manufactured.
  • cylinders may also be provided in order to push said conveyor 11 against the cam 14 and / or maintain it at the same level as the belt located in the oven 13.
  • the lower conveyor 11 is itself rigidly connected to a fixed element of the oven, by a connection symbolized at 18.
  • FIG. 3 shows the upper downstream conveyor 12 in three possible positions (a), (b), (c).
  • the lower downstream conveyor 11 is only slightly adjustable in height; the amplitude of its vertical displacement is only intended for the adjustment vis-à-vis the conveyor belt (not referenced) of the oven 13.
  • Position (c) is a position of maximum spacing between the conveyors. It is a maintenance position for which the cam 14 is in position C2 and the upper roll of the oven 13 in position C1.
  • the upper downstream conveyor 12 is pushed against the cam 14 which, being rigidly connected to an element such as the upper roller of the oven 13, thus makes it possible to maintain the conveyor 12 at a constant distance from said roller .
  • the profile of the cam 14 further allows to maintain the upper conveyor 12 at a minimum distance from the oven 13 regardless of the thickness of the felt 6 to be treated.
  • This profile comprises a vertical straight portion 141 surmounted by a curved portion 142 whose curvature is close to or identical to that of the upper roll of the oven 13.
  • the straight portion 141 may extend over the height of the end zone the upper conveyor 12 in the lower position and the height of the end zone of the lower conveyor 11.
  • the density of the felt upstream of the conveyors 11, 12 is of the order of 10 kg / m 3 .
  • the entrance to the oven 13 it is commonly between 10 and 200 kg / m 3 .
  • the thickness of the felt at the entrance of the conveyors 9, 10 is between 240 mm and 1200 mm; finally, that is to say at the entrance of the oven 13 the thickness of the felt may be between 20 and 300 mm.
  • the final product may have a thickness of between 10 and 500 mm.
  • the fibers can be of a very variable length; their diameter is between 3.5 microns and 5 microns.
  • the speed of conveyor belts can be between 1.5 and 40 m / min.
  • the figure 4 represents in perspective the upper downstream conveyor 12.
  • This conveyor is shown alone, and the side intended to supply felt oven, the latter is not shown.
  • This conveyor comprises a metal mesh mat 41 which comes into direct contact with the felt to convey it, said mat being itself driven by a non visible cake on the figure 4 but that we guess under the carpet and placed in the axis X-X ', said cake including gear wheels, one of which is driven by a transmission chain 42, said chain being itself driven by an engine 44 fixedly connected with the frame 45 of the conveyor.
  • Two cylindrical support rollers 43 (for example 120 mm in diameter) are fixed on the frame and on both sides thereof. The circumference of each roller can freely rotate about the axis of the roller (ie the X-X 'axis). It is these rollers which are intended to come into contact with cams 14 according to the invention. The fact that the circumference of the rollers is free in rotation limits the friction when the position of the conveyor is changed in the vertical direction and while the rollers bear on the respective cams.
  • the figure 5 represents in perspective a part of the device intended to receive the felt from the downstream conveyors and a part of which has been represented by the figure 4 .
  • the end portion of the conveying device receiving the felt from the downstream conveyors is called a roll.
  • Perforated metal pallets (in English: perforated lamellas) 51 receive the felt to drive it into the oven.
