The invention relates to devices intended for technological processes of obtaining glass fiber materials, mainly silica fabrics, and can be used separately or as part of technological lines in glass fiber factories and other enterprises.

The aim of the invention is to increase productivity.

FIG. 1 shows the device, a longitudinal section; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. 2

The device contains a bath 1, guides 2 located at equal distance from each other and forming a plane at an angle of 20-120 between their sides, plates 3, adjoining them and installed at an angle of 10-90 ° to the plane forming the surface, heat exchange apparatus 4, which is positioned from the bottom of the plane closely and made of thermoplastic tubes with fittings for inlet and outlet of the heat transfer medium. A mechanism for feeding and stacking fabric 5 is installed above the bath, the fabric is sampled by mechanism 6 including a system of rollers and an extraction pair of shafts. In the device, the plane for laying the fabric is inclined 30-80 ° in the direction of supply of the fabric, are made of pipes laid in parallel at the same distance from each other. The bath, the guides, the forming planes and the plates attached to them are made of materials resistant to aggressive media, for example, fiberglass or other polymeric material.

The device works as follows.

01

The fabric 7 to be chemically treated, for example leaching, in a molten state without tension, bends around the rollers and transversely folds in a transverse fold onto a plane made of guides 2 that are equally spaced from each other. at an angle of 20-120 ° and installed in the bath 1 filled with the working solution. Under the action of its own weight, as it accumulates, the fabric moves to the lower part of the plane, from which it is selected by mechanism 6, the passage through the system of guide rollers. The heat carrier is supplied to the tube space of the telcochanic 4 located under the plane. The heated working solution is guided upwards mainly between the guides 2 and flows directly into the leaching zone of the fabric. The layers of the working solution cooled in the upper part of the bath go under the heat exchanger, the passage through the heating zone is turbulent, and the heat transfer process is intensified.

The arrangement of the plates 3, conjugated with the guides 2 at an angle of 10-90 to the forming surface, and the arrangement of the guides create conditions for the directional movement of the heat flow — the heated solution moves upwards and is deflected by the plates located at certain angles from the middle to the opposite sides to the periphery, ensuring the entry and removal of the main part of the solution into the leaching zone, at the same time contributing to the melting of the transverse folds of the fabric when moving along the plane,

processing fiberglass woven materials in comparison with the known increases by 1.5-3 times, in addition, the intensification of the leaching process (by Na20) significantly increases.

The heat exchanger 4 is prevented from being mechanically damaged directly by the surface of the plane to accommodate the material being treated, which is the supporting structure for it. The location of the heat exchanger 4 in close proximity to the surface of the treatment contributes to the intensification of mass transfer directly in the leaching zone.
