Description

The invention relates to the construction of glass melting vessels for the production of continuous glass fiber.

. The aim of the invention is to increase the degree of thermal and chemical homogeneity of glass mass, productivity of a glass melting vessel, improving the quality of glass fiber, reducing the specific consumption of precious metals and electrical energy.

FIG. 1 shows a glass melting vessel, a longitudinal section; in fig. 2 - the same, side view.

The glass melting vessel comprises a housing 1, loading tubes 2, a heating screen 3, a homogenizing unit consisting of a heating element 4, filtering grids 5, technological windows 6, peaks 7 and a nozzle plate 8.

The glass balls through the feed tubes 2 enter the glass melting vessel, where they are melted. The molten glass mass is heated, forced through relatively large holes in the heating screen 3 and then supplied to the homogenizing unit. It slides over the inclined surfaces of the heating element 4 and the filter grids 5 of the homogenizing node, is additionally heated and projected, and passes through the small holes of the filter grids 5. The accumulated gases and overheated glass melt are discharged through the process windows 6. A part of the glass melt passing through the technological windows the windows 6 for forming 8 glass-fiber washes the visors 7 and acquires the same technological characteristics as the glass mass passing through the small apertures of 3t710 filter nets 5. From homogenizing The glass melt goes to the spin plate 8 for molding into glass fiber. The homogenizing node provides additional heating and filtering of the glass mass, removing gas inclusions and overheated glass mass, leveling the thermal characteristics, Q, which ultimately improves the performance of the glass melting vessel and the quality of glass fiber, reduces precious metal consumption and electricity. J5 Formula and 3 a glass melting vessel for forming continuous fiberglass, 8 comprising a body with a nozzle plate, a heating screen and a homogenizing unit, characterized in that, in order to increase the degree of thermal and chemical homogeneity of the glass mass, the performance of the glass melting vessel improving the quality of fiberglass, reducing the specific consumption of precious metals and electrical energy, homogenizing the node is made of a heating element in the form of a protruding rib with a technologist cal windows and canopies and filter fabrics.
