Definitions

  • the invention relates to production techniques mineral fiber mattress.
  • these mattresses are obtained by a two-phase process, producing the fibers properly say by drawing and freezing a molten mineral material at first then, association of a very large number of fibers that come together to form a mattress. Between the two phases, glass fibers or rock are sprinkled with a binder which will be polymerized at the end of the second phase. Once the mattress is finished, it remains to finish the elaboration to constitute a ready product to work. In particular, we must cut the edges length of the ribbon so that they are clear. This operation produces a residue, the edges of the mattress, which want to reuse. Likewise, certain falls resulting from further processing of panels or rollers constitute by-products that it is interesting to be able to recycle.
  • the object of the invention is to simplify and mechanize and to generalize the recycling of all scraps fibers produced during manufacturing and operation mineral fiber mattresses or at least reintroduce the maximum proportion tolerated by the quality to produce and increase this limit over techniques earlier.
  • waste can have two origins one, systematic, the rectified edges of the mattress, the other random, the waste produced during the exploitation of said mattress, exploitation which can provide waste under the most diverse conditions: most are due to production difficulties: it happens that we make unsaleable products for a reason or for another and more the product is developed or the more sophisticated the packaging, the greater the risk tall. So the so-called "surfaced" products, that is to say on the surfaces to which a facing has been pasted may have detachments, tears, appearance defects, etc. It is then impossible to sell or even use the panel or the roll produced. In this case as an alternative: either discard the finished product or properly recycle the essentials, that is to say the part fibrous.
  • the first solution poses problems about the environment and that's why we try as much as possible to reuse the fibers of such unsaleable panels or rolls.
  • Techniques various have been proposed to separate the facing of fibrous material and we assume that they have been implemented and we have here the bare panel or fiber roll. These are fibers - as well as fibers from edges of the mattress - we want to recycle. It's a process to perform this recycling as the invention offers.
  • the process for manufacturing the mineral fiber mattress includes steps following: fiber formation from a material in fusion, stretching, entrainment by a current gas ; the flow of fibers then being directed towards a conveyor that collects and drags them. Then, allogenic fibrous materials are added to the main flow of fibers, they were selected according to their density weighs, homogenized destructure and are driven at volumetric flow constant to be added to the main flow of fibers.
  • the materials are formed flakes.
  • allogenic fibrous materials have been stored before their introduction into the stream main fibers, their storage is done in silos where, in each, the fibers have a density defined mean.
  • Allogenic fibrous materials are removed in stocks of different average densities in quantities such as the average density resulting is compatible with those of the fibers of the main stream.
  • the invention therefore provides that weighings are carried out permanently at the exit of each silo.
  • the materials allogenic fibrous are mixed according to their densities and their respective amounts and regardless of their origin.
  • fibrous materials allogens are mixed and then destructured.
  • the first comb roller which defines the volumetric flow.
  • the second is settled so as to extract most of the materials fibrous reached him.
  • the process of the invention thus makes it possible to recycle as many products as possible, it allows therefore to almost completely eliminate pollution from the environment with mineral fibers from fibrous mattress, moreover this technique allows significantly lower production costs insofar as new fibers are replaced in the finished product by fibers which - otherwise - would have been lost.
  • Each centrifuge device 1 is isolated from the outside by a wall 6 which constitutes a suction hood.
  • the fiber mat 5 is driven on a very long in the direction of arrow 7. This length is most often a hundred of meters.
  • the system transporting the mattress is not shown.
  • the mattress 5 will then be cut to constitute either rolls or panels.
  • the shaping of the mattress for the realization of the finished product requires that the longitudinal edges used to be irregularities of the mattress are eliminated.
  • Sure the production line, so we have to proceed systematic longitudinal cutting of selvedges. We see them at 9 in Figure 1. They are driven to a shredder 10 which transforms into flakes of fibers whose dimensions range from one to a few centimeters. These flakes, animated by the air supplied by a blower 11 are conventionally returned directly upstream, where the fiber mat is developing. There, we put them back in the mattress, either between the extractor hoods or either more homogeneous, according to the technique described in the FR 2,559,793, directly in the flow of fibers from each of the range hoods.
  • FIG. 2 represents the process of the invention for prepare, select, store, dose while destructuring then finally distribute the waste as well those from the edges on the line than those from falls or workmanship, offline.
  • Some elements are the same as those in Figure 1, especially everything which concerns the line itself, extractor hoods 28 to mattress 5 at the end of the line.
  • the treatment longitudinal edges 9 uses shredders 10 and the blowers 11.
  • a motorized caster comes to lay the shore flat while pinching it. This avoids bank breaks downstream of the cutting saw.
  • the length of the vertical or oblique part is approximately 2.5 m (depending on the depth of the cellar).
  • the distance between the horizontal ducts is adjustable by means of two motors and two screw-nut assemblies.
  • the vertical conduits have at their upper end a cone which keeps the vertical part fixed, despite the variation in distance between the horizontal conduits.
  • hammer mills are used as a shredder.
  • the mill consists of a 45O mm rotor diameter a length of 4OO mm, it includes 90 hammers spread over three rows, its rotation speed is around 1500 revolutions per minute.
  • the grid is made of steel manganese with dimensions 4O x 4O mm.
  • a fan 11 ensures the evacuation of the flakes.
  • the characteristics of the fan are calculated in order to obtain a speed of 20 m / sec in pipes with diameters from 2OO to 250 mm, i.e. a flow rate 4 of approximately 3500 m 3 / h.
  • the total pressure being calculated as a function of the pressure losses due to the installation of the pipes.
  • the materials used for the impeller and the scroll have good abrasion resistance.
  • distributors 29 which are capable of orienting the flakes, either towards the duct 30 if, for example they are light, or towards the duct 31 if they are denser, they then join the main light 21 or heavy 22 circuit which directs them respectively to the silos 21 or 24.
  • the circuit for scraps or finished products from poor workmanship 18: shredder 17, blower 19, distributor 20 then main pipes 21 or 22 is itself consisting of elements which are exactly the same as those which have just been described. It can be seen simply in FIG. 2 that the selvedge circuit has joined, after separation according to density, the circuit of falls and poor workmanship so as to constitute a single circuit, that of allogenic fibrous materials. Passage through silos such as 23 or 24 is therefore systematic.
  • silos are, for example, cylinders with a vertical axis with a capacity of 4 m 3 each. Each is surmounted by a capacitor (43, 44) which allows the separation of air and flakes. They are fitted with filters to remove dust before the air is recycled.
  • a capacitor 43, 44
  • filters to remove dust before the air is recycled.
  • the light products / heavy products border was placed at a density of 20 kg / m 3 .
  • the distributors 20 or 29, on each of the flake supply circuits are switched according to the density of the flakes which feed them, either on the conduit 21 if their density is low, or on the conduit 22 if their density exceeds the limit fixed.
  • the rest of the recycled flake route, at the output from the silos (23, 24) is identical to that of the figure 1, there are successively the scales 25, the belts treadmill 26 and the main treadmill 27.
  • the element essential new in the circuit is machine 32. It it is a machine called “ball breaker", its function is multiple. First of all the usual function of this type of machine which is to "break" tangles of fibers. Indeed during previous multiple manipulations, the flakes could be packed, compacted, nested and there try to restore them to their original configuration, their integration into the new fibers will be found all the better. We even want to go further: destructuring, "burst" the original flakes to facilitate their integration into the flow of new fibers and so in the mattress.
  • a second function of this machine which is not usually required in breakers is to homogenize the flakes that have origins multiple: selvedges on the one hand and finished products on the other but also among these, flakes that have a different story from each other.
  • a third completely new function is also fulfilled by this machine. The function is new because the problem posed here is not usual in workshops where such machines are installed, it is a question of making constant the flow at the outlet of the scales, flow which varies periodically, as we've seen. You have to "smooth" the variations cyclical so that excess flow over at the average flow compensates for the deficiencies. We obtain thus a constant volumetric flow.
  • the machine 32 is shown schematically in the figure 3.
  • the product leaves the treadmill 33 which is shown in Figure 2, this raised the flakes above machine, left.
  • the machine entry in 34 is presents as a trough whose bottom is constituted by the treadmill 35. The latter is driven at constant speed, the flakes will therefore deposit there periodically as delivered by the balance 25 in operation.
  • This conveyor belt 35 in turn feeds a strip conveyor 36 which constitutes the bottom of a level tank constant, in fact, it is equipped with an ultrasonic system not shown which allows material flakes allogeneic fibrous fibers which charge it to occupy a thickness constant.
  • the engine treadmill drive locks up and the fiber supply is immediately stopped.
  • the flakes occupy in the tank 37 a defined height chosen so that the fibers are driven upward at a constant rate which corresponds to the average weighing of the balance 25.
  • the drive upwards is carried out thanks to the spiked mat 38 in translation at constant speed. This speed can be adjusted by a manual control not shown.
  • the flakes At the top of the spiked carpet, the flakes reach the comb roller 39 which has four generators equipped with spikes and turns against the current, it hunts down the excess flakes, ensuring flow perfectly regular fibers. By the way, the teeth combs penetrate the flakes held by the carpet tips by causing the desired "destructuring".
  • a second identical roller 40 which turns in the direction of flow, fulfills a neighboring function and extracts all fibers of the spiked apron and returns them on the inclined plane 41, towards the outlet 42 of the machine.
  • conveyor belt 45 which supplies a fan not shown. This sends the regular flow of allogenic fibrous materials delivered by machine 32 to distributor 46 which feeds as many pipes as there are hoods 28. Before dispensing into each hood, again, distributors 47 separate the fiber stream recycled into two equal streams which feed two by two the extractor hoods where they will be mixed with the flow main fiber.
  • the invention therefore makes it possible to supply the lines of production of rock fibers or glass fibers immediately after fiberizing machines with regular flow of destructured, open flakes.
  • These two elements regular feeding on the one hand, destructuring of each other’s flakes facilitate the incorporation of allogenic fibers in the flow new fibers.
  • the hourly quantity introduced (in silo B since its density, 90 kg / m 3 is greater than the fixed limit, 30 kg / m 3 ) corresponds to 8% of production while the quantity extracted is 11%.
  • the average stock density is increasing. This parameter - management of waste stocks - is in addition to those already mentioned. It is one of the elements to consider before choosing the average density and the quantity to be reintroduced.
  • the glass fiber production line according to the method of European patent EP A 0091 866 comprises six centrifuge heads with a production of 120 tonnes / day.
  • the net width is 2.4O m and shore waste constitutes 4% of production.
  • the technique of the invention therefore not only allows to permanently reintroduce falls from edges of the mattress, while prior techniques forced to interrupt this reintroduction during production changes, but in addition it authorizes the recycling of waste whatever its source and whatever the nature of their fibers.
  • the only constraint is that you need sufficient storage to wait until production is compatible with the nature of the fibers that we want to reintroduce.
  • Systematic recycling of fibers from finished product is particularly favorable to preservation of the environment.
