Smelting furnace feeding device

Technical Field

The invention relates to the technical field of glass, pottery or other ceramic manufacturing, in particular to a smelting furnace feeding device.

Background

The principle of the prior art for casting glass bottles is to melt the glass and form it by blowing. Generally, when glass bottles are produced in large quantities, the steps are as follows: (1) melting: filling the glass blocks into a melting furnace by adopting a shovel for melting to form molten glass (namely molten glass); (2) selecting materials: firstly, one end of an iron pipe or a stainless steel pipe with the length of about 1200-1500 mm is placed in a furnace and heated to a proper temperature (so as to be convenient for sticking molten glass); then dipping the glass melt in the crucible by adopting the iron pipe or the stainless steel pipe; (3) bubble blowing: rolling the picked materials into glass material balls in a rolling material plate or a rolling material bowl, blowing air into the softened glass from one end of a blowing rod on a special manufacturing table to enable the glass material balls to become hollow thick-wall small bubbles (or blowing the glass material balls into the small bubbles, or positively forming the small bubbles by utilizing the flowability of the glass); (4) molding: under the condition of continuous rotation and air blowing, the material bubble is continuously expanded, and during operation, the material bubble is molded by using special hand tools such as pliers, scissors, tweezers, clamping plates, sample plates and the like or trimmed by using scissors; (5) finishing: after annealing, the product should be processed and finished by cutting, baking and the like.

Chinese patent publication No. CN101588995B discloses a glass melting furnace having a melting tank for receiving molten glass and containing a molten pool of molten glass, the melting tank having walls located above the glass forming a front wall, a rear wall, side walls and a cover, respectively, and constituting a melting chamber, and at least one hot combustion air inlet, at least one hot exhaust gas outlet, and at least one burner for introducing a first fuel into the chamber and at least one injector for introducing a second fuel into the chamber; the injector is arranged on a wall different from the wall on which the burner is positioned and at a distance from the burner in a region between the cover and a horizontal plane lying in a plane higher than or equal to the horizontal plane passing through the lower rim of the hot air inlet, and in that the injector can be adjusted in a complementary manner with respect to the burner according to the flow rate, thereby making it possible to reach 100% of the total injected amount of the first and second fuels used by the injector and the burner, irrespective of whether the first and second fuels have the same or different characteristics.

The above patent technology also has the following technical problems: when the glass solution in the melting tank is nearly used up, a shovel is used for putting the glass blocks into the melting tank, so that the glass blocks are continuously fed into the melting tank, and when the glass blocks fall into the melting tank, the glass blocks easily enable the residual glass solution in the melting tank to splash or the broken glass slag to splash during feeding; in any case, the above-mentioned problems are very dangerous and easily cause accidental injuries to workers.
