Definitions

  • the invention relates to techniques for producing mineral fiber mattresses.
  • these mattresses are obtained by a two-phase process, production of the fibers proper by stretching and freezing of a molten mineral material firstly, then, association of a very large number of fibers which are combined to constitute a mattress. Between the two phases, the glass or rock fibers are sprinkled with a binder which will be polymerized at the end of the second phase.
  • the longitudinal edges of the ribbon must be cut so that they are clear. This operation produces a residue, the edges of the mattress, which we want to reuse.
  • certain falls resulting from the subsequent operation of the panels or rollers constitute by-products which it is advantageous to be able to recycle.
  • the object of the invention is to simplify, mechanize and generalize the recycling of all the fibrous scraps produced during the manufacture and exploitation of mineral fiber blankets or at least to reintroduce the maximum proportion thereof tolerated by the quality to produce and increase this limit compared to previous techniques.
  • the waste can have two origins, one systematic, the rectified edges of the mattress, the other random, the waste produced during the operation of said mattress, an operation which can provide waste under the conditions the most diverse: most are due to production difficulties: sometimes unsaleable products are made for one reason or another and the more the product is developed or the more sophisticated the packaging, the greater the risk.
  • surfaced products that is to say on the surfaces of which a facing has been pasted, may exhibit detachments, tears, appearance defects, etc. It is then impossible to sell or even use the product panel or roll. In this case, there is only one alternative: either discard the finished product or recycle the essentials, that is to say the fibrous part.
  • the first solution poses problems concerning the environment and that is why we try to reuse the fibers of such unsellable panels or rolls as much as possible.
  • Various techniques have been proposed for separating the facing from the fibrous material and we assume that they have been implemented and that the panel or the bare fiber roll is available here. It is these fibers - as well as the fibers from the edges of the mattress - that we want to recycle.
  • the invention proposes a process for carrying out this recycling.
  • the method of manufacturing the mineral fiber mat comprises the following steps: forming fibers from a molten material, drawing, entrainment by a stream of gas; the stream of fibers then being directed towards a conveyor which gathers them and drives them. Then, allogenic fibrous materials are added to the main flow of fibers, they have been selected according to their density and are driven at constant volumetric flow.
  • the materials are formed into flakes.
  • non-native fibrous materials were stored before their introduction into the main stream of fibers, their storage is done in silos where, in each, the fibers have a defined average density.
  • Allogenic fibrous materials are taken from stocks of different average densities in quantities such that the resulting average density is compatible with those of the fibers of the main stream.
  • the invention therefore provides that weighings are carried out continuously at the outlet of each silo.
  • the non-native fibrous materials are mixed according to their densities and their respective quantities and regardless of their origin.
  • the non-native fibrous materials are mixed and then destructured.
  • a device for implementing the manufacturing method of the invention, it comprises a constant level tank, a carpet with rising tips and two comb rollers in the upper part.
  • the first comb roller which defines the volumetric flow rate.
  • the second is regulated so as to extract most of the fibrous materials that have reached it.
  • the process of the invention thus makes it possible to recycle the maximum of possible products, it therefore makes it possible to almost completely eliminate pollution of the environment by mineral fibers coming from fibrous mattresses, moreover this technique makes it possible to reduce the costs of production 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 over a very long length in the direction of arrow 7. This length is most often a hundred meters.
  • the system carrying 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 production of the finished product requires that previously the irregular longitudinal edges of the mattress be eliminated.
  • FIG. 1 it is this technique of introducing the fibers into the extractor hood which is shown diagrammatically, the introduction is made at each layer of new fibers such as 2 by the conduits 12, two in number in each of the extractor hoods. Between the blower 11 and the conduits 12 the recovered fibers must therefore follow a long path 13 to a distributor 14 which directs identical recycled fiber flow rates over the four suction hoods shown. They thus pass through the four pipes 15 before arriving at the distributors 16 which also divide the flow intended for each of the conduits 12.
  • FIG. 17 shows a shredder into which the panels 18 (or the rollers) are removed, stripped of their surface coating.
  • the blower 19 propels the airborne flakes to the distributor 20 which - depending on the original density of the panel 18 (or of the roller) sends them through the pipe 21 to the storage silo 23 - reserved for example for products light, the others being transferred via line 22 to silo 24 reserved, he in the example, for the densest products.
  • FIG. 2 represents the process of the invention for preparing, selecting, storing, dosing while destructuring then finally, distributing the wastes as well those coming from the edges on the line as those coming from the falls or workmanship, offline. Certain elements are the same as those in FIG. 1, in particular everything relating to the line proper, from the suction hoods 28 to the mattress 5 at the end of the line.
  • the processing of longitudinal edges 9 uses shredders 10 and blowers 11.
  • a motorized caster comes to lay the bank flat while pinching it. This prevents breakage of the edge 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 conduits can be adjusted using two motors and two screw-nut assemblies.
  • the vertical conduits have at their upper end a cone which makes it possible to keep 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 450 mm diameter rotor, a length of 400 mm, it comprises 90 hammers distributed over three rows, its rotation speed is of the order of 1500 revolutions per minute.
  • the grid is made of manganese steel, dimensions 40 x 40 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 the 200 to 250 mm diameter pipes, 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 silos 21 or 24.
  • the circuit of scraps or finished products from poor workmanship 18: shredder 17, blower 19, distributor 20 then channeled main tions 21 or 22 is itself made up 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 had been 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 fixed limit.
  • the number of silos shown in Figure 2 is two but it is obvious that a finer classification of the flakes to be recycled can be interesting. The number of silos is then multiplied, which makes it possible to refine the adequacy between the respective densities of the recycled flakes and the mattresses in production.
  • a second function of this machine which is not usually required in bale breakers, is to homogenize flakes which have multiple origins: selvedges on the one hand and finished products on the other but also among these, flakes who have a different history 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 the 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 have seen . It is necessary to "smooth" the cyclical variations so that the excess of flow compared to the average flow compensates for the deficiencies. This gives a constant volumetric flow.
  • the machine 32 is shown diagrammatically in FIG. 3.
  • the product leaves the conveyor belt 33 which, for its part, is represented in FIG. 2, which has raised the flakes above the machine, on the left.
  • the entry of the machine at 34 is in the form of a trough, the bottom of which is constituted by the conveyor belt 35.
  • the latter is driven at constant speed, the flakes will therefore deposit there periodically as they are delivered by balance 25 in operation.
  • This conveyor belt 35 in turn feeds a conveyor belt 36 which constitutes the bottom of a tank at constant level, in fact, it is equipped with an ultrasound system not shown which allows the flakes of non-native fibrous materials which load it with water. '' occupy a constant thickness.
  • the drive motor of the treadmill 35 is blocked and the fiber supply is immediately stopped.
  • the flakes occupy in the tank 37 a defined height which is chosen so that the fibers are entrained upwards at a constant flow rate which corresponds to the average weighing of the balance 25.
  • the entrainment upwards is carried out using the spike belt 38 in translation at constant speed. This speed can be adjusted using a manual control, not shown.
  • the flakes reach the comb roller 39 which has four generators equipped with spikes and turns against the current, it drives down the excess flakes, thus ensuring a perfectly regular flow of fibers. Furthermore, the teeth of the combs penetrate into the flakes held by the tips of the carpet, causing the desired "destructuring".
  • a second identical roller 40 which rotates in the direction of flow, performs a similar function and extracts all the fibers from the spiked apron and returns them on the inclined plane 41, towards the outlet 42 of the machine.
  • the conveyor belt 45 which supplies a fan (not shown). This sends the regular flow of allogenic fibrous materials delivered by the machine 32 to the distributor 46 which feeds as many pipes as there are extractor hoods 28.
  • distributors 47 separate the flow of recycled fibers into two equal flows which supply the extractor hoods in pairs where they will be mixed with the main flow of fibers.
  • the invention therefore makes it possible to supply the production lines for rock fibers or glass fibers immediately after the fiberizing machines with a regular flow of open, destructured flakes.
  • These two elements regular feeding on the one hand, and destructuring of the flakes on the other, each contribute to facilitate the incorporation of allogenic fibers into the flow of new fibers.
  • silo B In the concrete case of the example, we chose the latter possibility and we therefore took all of the products to be recycled in silo B, the balance of which was adjusted to deliver an average of 275 kilos per hour.
  • the machine 32 of FIG. 2 is adjusted so as to precisely ensure the constant volumetric flow rate of the quantity retained.
  • the stock of waste contained in silo B is slightly lowered.
  • the hourly quantity introduced in silo B since its density, 90 kg / m 3 is greater than the fixed limit, 30 kg / m 3
  • 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 2.40 m and shore waste constitutes 4% of production.
  • the technique of the invention therefore makes it possible not only to permanently reintroduce the falls originating from the banks of the mattress, whereas the prior techniques required this reintroduction to be interrupted during production changes, but in addition it allows recycling of waste whatever their origin and whatever the nature of their fibers.
  • the only constraint is that there must be sufficient storage to allow waiting for production to be compatible with the nature of the fibers to be reintroduced.
  • the systematic recycling of fibers from finished products is particularly favorable for the preservation of the environment.
