3. because the utility model can improve heat utilization rate while minimizing fuel usage quantity, and then effectively decrease offgas discharge amount, so decrease the waste gas such as sulfide, oxynitride got rid of in production process to the pollution of environment;
4. the utility model can reduce the size of the deep water pocket at card neck place, and while reducing water bag manufacturing cost, also facilitate the descending operation of deep water pocket, the prior usage quantity being the reduction of water coolant, has saved water resources;
5. the utility model structure is simple, easily manufactured, can carry out, also can carry out technological transformation when melting furnaces cold repair when designing new production line melting furnaces.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the utility model embodiment 1;
Fig. 2 is the structural representation of the utility model embodiment 2.
Embodiment:
Embodiment 1:
As shown in Figure 1, a kind of reducing card neck of Flat Glass Furnace, it comprises: melting furnaces fining end 1, card neck 2 is connected with at the liquid outlet 1a place of melting furnaces fining end, described card neck 2 comprises a card neck straight channel 2a along the distribution of melting furnaces fining end length direction, the width of described card neck straight channel 2a is less than the width of same level melting furnaces card neck passage, and the width of described melting furnaces fining end 1 is 6.5 times of card neck straight channel 2a width, and described card neck straight channel 2a is provided with the deep water pocket with its corresponding matching.
Width due to card neck straight channel 2a is less than the width of same level melting furnaces card neck passage, therefore deep water pocket length shorter is herein arranged on, while reduction water bag size, facilitate descending operation, the more important thing is the usage quantity decreasing 25% ~ 65% water coolant than wide card neck, save a considerable number of water resources.
In addition, because the large width of card neck straight channel 2a is less than the width of same level melting furnaces card neck passage, so coordinate with deep water pocket, to form " dog-hole " also less, thus decrease the backflow of glass metal from operate portions, and then decrease the thermosteresis of Repeat-heating of glass metal.High temperature gas flow from melting furnaces fining end field flow orientation melting furnaces cooling end region is played and better intercepts sealing process, decrease the heat energy loss that thermal convection is taken away by melting furnaces cooling end, play cost-saving effect.
Card neck expanding reach 3 is connected with in one end of described card neck straight channel 2a, described card neck expanding reach 3 is barrel-shaped, its barrel of bottom surface 3a is connected with card neck straight channel 2a, and perpendicular with card neck straight channel 2a, and the axis of described card neck expanding reach 3 and the axis conllinear of card neck straight channel 2a.
The opening end of described card neck expanding reach 3 is connected with melting furnaces cooling end 4, and the width of the opening end of card neck expanding reach 3 is 2 times of card neck straight channel 2a width.The length of described card neck straight channel 2a is 2 times of card neck expanding reach 3 length.
Embodiment 2:
As shown in Figure 2, a kind of reducing card neck of Flat Glass Furnace, it comprises: melting furnaces fining end 1, card neck 2 is connected with at the liquid outlet 1a place of melting furnaces fining end, described card neck 2 comprises a card neck straight channel 2a along the distribution of melting furnaces fining end length direction, the width of described card neck straight channel 2a is less than the width of same level melting furnaces card neck passage, and the width of described melting furnaces fining end is 5 times of card neck straight channel 2a width, and described card neck straight channel 2a is provided with the deep water pocket with its corresponding matching.
Because the large width of card neck straight channel 2a is less than the width of same level melting furnaces card neck passage, therefore deep water pocket length shorter is herein arranged on, while reduction water bag size, facilitate descending operation, the more important thing is the usage quantity decreasing 25% ~ 65% water coolant than wide card neck, save a considerable number of water resources.
In addition, because the large width of card neck straight channel 2a is less than the width of same level melting furnaces card neck passage, so coordinate with deep water pocket, to form " dog-hole " also less, thus decrease the backflow of glass metal from operate portions, and then decrease the thermosteresis of Repeat-heating of glass metal.High temperature gas flow from melting furnaces fining end field flow orientation melting furnaces cooling end region is played and better intercepts sealing process, decrease the heat energy loss that thermal convection is taken away by melting furnaces cooling end, play cost-saving effect.
Card neck expanding reach 3 is connected with in one end of described card neck straight channel 2a, described card neck expanding reach 3 is tubaeform, the hydraucone place of its one end is connected with melting furnaces cooling end 4, its the other end is connected with card neck straight channel 2a, and the axis conllinear of the axis of card neck expanding reach 3 and card neck straight channel 2a.
