    A method and apparatus for producing glass filaments in which glass filaments in a spinning chamber are contacted by a mist comprising a mixture of compressed air and a treatment liquid, the constituents of the mist being mixed in a first part of a heat exchanger adjacent the spinning chamber and passing to a second part of the heat exchanger more remote from the spinning chamber before being delivered from that second part into the spinning chamber. <IMAGE>

    The invention relates to equipment for the production of glass fibers.
    Closest to the present invention is a device for the manufacture of fiberglass, including a feeder with a draw plate.
    and perforated distribution pipes for supplying the reagent in the form of a mist to the underfilter space 1.
    In order to prevent the glass surface of the spinneret from being wetted directly by means of a gas or a gas mixture, carbon-containing or utra-like material is deposited in the under-filler space, which is deposited on surfaces that should not be wetted. 15
    To do this, an inert gas is introduced with a relatively small amount of organic gas (hydrocarbon gas), which contains a hydrogen component in the flow area of the glass. In this case, both gases decompose at a high temperature.
    The gas (gas mixture) is introduced by means of a glass tank, which is inclined to the plane of flat pipe filaments, passing in longitudinal direction, where
    At the same time as fillers, and thus to the hottest areas of the under-filler space, the bends have a large number of outflow slots.
     Since for the realization of the gas flow divided into the slits, there is only a flat face, made in the form of a ram, the distribution pipe, and the hottest components of the gas tend to rise upwards, and the colder components go down. distribution, in which the coldest parts of the gas are at the very bottom, and practically already decomposed components are on the distribution slots. In this case, it is not excluded that non-evaporating gas is collected in the lower part of the pipes, i.e., it is not used continuously, and since the nearest hottest areas of the underfill area of the pipes, through which the hottest part of the gas also passes, high temperatures are still subject to premature destruction. This contributes to the separation.
    In addition, in the known devices voz-. no distribution problems. L precisely. the closer the gas mist escaping through the slot to the outflow holes for the glass, and to the completely non-solidified strands here, the less time and space the gas mist has in order to spread along the sides in a distributed state. It should also be borne in mind that due to the continuous: a glass filament removed at high speed, a constant, directed towards the removal air flow arises, which captures and carries with it the fog as soon as it falls into its area. The purpose of the invention is to improve the quality of heat distribution. This goal is achieved by the fact that a device for making fiberglass, including a feeder with a draw plate and perforated distribution pipes for supplying the mist reagent to the subfilm reagent, is provided with a distribution wall installed in front of the perforated separation pipe openings. Distribution wall is made of mesh. The distribution wall is made in the form of a sheet mounted at an angle to the feeder. FIG. 1 shows a device, a vertical section; in fig. 2 shows a device, another variant, a vertical section ;, in FIG. 3 is a view along arrow A in FIG. 2. The device consists of a feeder 1 of refractory material, a die plate 2 of a plate or a platinum alloy. Spunner plate 2 is provided with spindles 3 on which a dowel cone 4 is formed, from which the string 5 is continuously removed. In order to fill the subfilter spaces with a fog covering all the filaments, a heat exchanger 6 is provided (Fig. 1). A heat exchanger is installed adjacent to the nozzle plate 2 and consists of a mixing tube 7 and an outlet tube 8, which are connected to each other by a knee 9. The outlet tube is filled with openings 10. In front of the openings 10 there is a distribution wall II, made of mesh or sheet mounted at an angle to the feeder. In the case of the distribution of the distribution wall in the form of a sheet, the mixing tube 7 and the outlet tube 8 are fixed on the outer stanchion of the inclined shelf 12 of the angle bracket 13 (Fig. 2 and 3). In addition, in this example, the heat exchanger is implemented as a replaceable unit, and the angle 13 with its horizontal shelf 14 can be so far moved on the guides 15 formed by the corners 16 attached to the machine bed, until it reaches the stop the surface of the side wall 17 rests against the outer wall of the thermal insulation of the feeder 1. The outlet pipe 8 which is farthest from the heated underfilter zone hangs, on the stud 18 placed on the lower side of the horizontal shelf 14,. The distributor wall can also it is designed as a replaceable assembly for this to be made movable on fixed on tannin cantilevers x 19 ribs may be mounted on the sheet 20. The apparatus operates as follows. The glass mass enters the feeder 1, from which the filters 3 of the spin plate 2 are continuously pulled out of the cone 4 into the thread 5. Since the temperature in the feeder is from 1000 to 1250 ° C, then in the space below the dies 3, in the so-called sub-filter space There is a relatively high temperature due to radiation. In order to fill the underfilter space with a mist wrapping around all the threads, a heat exchanger 6 is provided. The concept mist is used to denote an outgoing gas or gas mixture or a pairing liquid, which can be, for example, a lubricant, an antistatic agent, but also plain water or a mixture . Compressed air is first introduced into the mixing tube 7 (pressure about 0.5 bar), and then a liquid is treated, for example, an oil sizing agent. These two components enter as a relatively cold environment into the mixing tube 7 located closer to the hot part of the under-filter space, are heated and evaporated in the form of an air-liquid mixture, then get into the cooler area of the heat exchanger remote from the under-filter space and exit through the holes 10. Thus, the temperature difference between the media used to produce the gas mixture, which facilitates the removal of the yarn and / or the processing of the formed yarn, is used to cool the parts ploobmennika finds schihs closer to the hotter parts podfilernogo space. The exiting mist falls on the separation wall, made in the form of a mesh wall 11 or in the form of a sheet mounted at an angle and is divided along it along the length of the pipe, i.e. across the width of the die plate, passes through the mesh wall, and on the back side of the dividing surface is carried along by the air flow created by removing the thread, thus covering individual threads.
    Compressed air and liquid can also be mixed already before entering the pipe 7. If the distribution wall is made in the form of a sheet, it is due to the fact that the fog is directed towards the wall formed by sheet 11. spreads wide. If the spinnerets are arranged in groups, for example, in a manner in which there are always 5 or 6 or more dieters of one row with a total number of rows, for example, equal to twelve, there is a gap width equal to or more than the spinneret, then edges 20 on sheet 11 can direct fog to these groups.
    Just as shown in FIG. I, and in this case, the fog rising in the direction of the arrow carries away the air flow created by the filament yarns.
