Изобретение относится к про№пнленности строительных материалов, в частности к электрическим стекловаренным печам большой производательности.The invention relates to the construction of building materials, in particular to large-capacity electric glass melting furnaces.

. Известна трехфазная электрическая стекловаренная печь для непрерывного производства стекла с варочным бассейном и электродами [I].. Known three-phase electric glass melting furnace for the continuous production of glass with a cooking pool and electrodes [I].

Известная печь, характеризующаяся наличием большой поверхности боковых стен варочного бассейна, при заданной поверхности варочной части и высоте бассейна не обеспечивает полную тепловую симметрию вырабатываемой стекломассы.The known furnace, characterized by the presence of a large surface of the side walls of the cooking pool, for a given surface of the cooking part and the height of the pool does not provide complete thermal symmetry of the produced glass melt.

Неравномерно'е расположение элек- ‘ тродов относительно поверхности варочного бассейна вызывает неравномерно сущности и достигаемому результату ный прогрев стекломассы,что приводат к неравнозначной, варочной способности каждой единицы площади поверхности бассейна. Вследствие этого, при повышении варочной способности печи _ путем увеличения электрической мощности, отдельные участки варочного бассейна перегреваются, шихта, экранизирующая поверхность расплава в этих местах преждевременно про10 к предлагаемой является трехфазная ‘ эле ктрйчёск ая сТёклбварён н ая печь .непрерывного действия,содержащая варочный бассейн в виде шестигранной призмы, стержневые вертикальные элек-. трода, проток и выработочный бассейн [2] .The uneven arrangement of the electrodes relative to the surface of the cooking pool causes uneven nature and the achieved resultant heating of the glass melt, which leads to the unequal cooking ability of each unit of the surface area of the pool. As a result, while increasing the cooking ability of the furnace _ by increasing electric power, certain sections of the cooking pool overheat, the mixture screening the surface of the melt in these places is prematurely offered is a three-phase continuous heating furnace containing a cooking pool in in the form of a hexagonal prism, rod vertical elekt. a trode, a duct and a production pool [2].

Неравномерное расположение электродов относительно поверхности ва- _; рочного бассейна и относительно его (Стен создает неравномерный прогрев 'стекломассы, особенно в пристенных зонах, и вызывает пониженный, по отношению к возможному, съем стекломассы с единицы поверхности варочного бассейна. Центральный поток сваренной стекломассы, перемещаясь .через блок электродов, увлекает в проток слои стекломассы, примыкающие к стенам бассейна. Все это не позволяет в значительных объемах увеличивать производительность печи.Uneven arrangement of electrodes relative to the surface _; of the pool and relative to it (Sten creates uneven heating of the glass melt, especially in the near-wall zones, and causes a lower, in relation to the possible, removal of the glass melt from a surface unit of the cooking pool. The central flow of welded glass melt moving through the electrode block entrains layers in the duct glass melt adjacent to the walls of the pool, all this does not allow to significantly increase the productivity of the furnace.

Цель изобретения - повышение сьема стекломассы с единицы поверхности варочного бассейна и равномерности .ее нагрева, а также увеличение производительности. ,The purpose of the invention is to increase the removal of glass from a unit surface of the cooking pool and the uniformity of its heating, as well as an increase in productivity. ,

Поставленная цель достигается ..тем, что в трехфазных электрических стекловаренных печах с варочным бассейном в форме шестигранной Призмы, стержневые электроды равномерно установлены по периметрам расположенных концентрично относительно отверстия протока правильных шестиугольников в вершинах и на сторонах. Кроме того, печь выполнены с дополнительными протоками и выработанными -бассейнами.The goal is achieved .. that in three-phase electric glass melting furnaces with a cooking pool in the form of a hexagonal Prism, the rod electrodes are uniformly installed around the perimeters of the regular hexagons concentrically relative to the duct opening at the vertices and sides. In addition, the furnace is made with additional ducts and exhausted-pools.

. Такая конструкция печи обеспечивает симметричную равномерную нагрузку фаз питающего трехфазного трансформатора, равномерный прогрев стекломассы по всей площади варочного бассейна,и, следовательно, увеличение сьема стекломассы.. This design of the furnace provides a symmetrical uniform load of the phases of the feeding three-phase transformer, uniform heating of the glass melt over the entire area of the cooking pool, and, consequently, an increase in the removal of glass melt.

Расположение отверстия протока в центре блока электродов сводит к минимуму термическую неоднородность выработочного потоки стекломассы.The location of the duct opening in the center of the electrode block minimizes the thermal heterogeneity of the production flow of the molten glass.

The invention relates to the construction of building materials, in particular to electric glass melting furnaces of high productivity,. The three-phase electric glass melting furnace is known for continuous production of glass with a cooking basin and electrodes I. The known furnace, which is characterized by the presence of a large surface of the side walls of the cooking pool, does not provide the full thermal symmetry of the glass melts for a given surface of the cooking part. ... The uneven arrangement of the electrodes relative to the surface of the cooking basin causes an unequal heating of the glass melt, which leads to an unequal cooking ability of each unit of surface area of the basin. As a result, as the cooking capacity of the furnace increases by increasing the electrical power, certain parts of the cooking pool overheat, the charge, the screen-melting surface in these places melts prematurely, which ultimately causes an increase in the specific energy consumption per unit of welded glass melt. In addition, Schuka glass melting with volatile comBinesTime premature charging of the charge at a fraction of a fraction of the loss of cbmp6nthe1a, and7 syoed6va5ShGGeGr1Gshshn 4Sho-T ... of the glass melt and misalignment of the electrons To eliminate such phenomena, it is necessary to lower the electric power of the furnace below the possible limit and reduce the glass mass per unit surface of the brewhouse of the furnace basin. :: Ebboløyo blockA on three yychy entities and the achieved result to the proposed three-phase electric heater 1:; 1 -6 continuous continuous furnace, a high-power hex-shaped swimming pool, with vertical hectars. 1 Uneven arrangement of electrodes relative to the surface of the heat sink and its relative | Wall creates an uneven heating of the glass mass, especially in the near-wall zones, and causes a decrease in the glass mass from the surface unit of the cooking basin. The central stream is welded glass melt, moving through the electrode block, carries into the duct the layers of glass melt, which are attracted to the walls of the pool. All this does not allow, in significant volumes, to increase the productivity of the furnace.

The location of the duct opening in the center of the electrode block minimizes the thermal heterogeneity of the Bbipa6ovo4Horo glass melt. An increase in the number of pa electrodes: placed outside the hexagons in addition to the block, permits an increase in the area of the cooking basin while maintaining the load on the transformer phases and uniformly heating the glass mass throughout the volume. Figure 1 shows the section BB in figure 2; figure 2 - section aa in figure 1; Fig. 3 shows the arrangement of the furnace electrodes with an increased cooking basin and one production basin; Fig. 4 shows the arrangement of the electrodes of the furnace with four channels and production pools.
