Description
Technical field
The utility model belongs to opticglass and founds technical field, is specifically related to a kind of glass kiln melting tank efficiently, is mainly used in the kiln that high-quality optical glass continuous smelting is produced.
Background technology
Environmental protection or the non-environmental protection optical glass of current domestic production crown class, flint class commonly use melting pool, are generally divided into by type of heating: all-electric melting pond, full flame molten bath and flame mix molten bath with electricity.All-electric melting tank furnace environmental pollution is little, and structure is also relatively simple, and cost is low, but process debugging is complicated, and quality stability is poor, at present can only production part crown board or flint class glass.Full flame molten bath kiln structure is simple, and utility appliance is few, cheap, but to glass liquid heating mainly upper strata, lack heating bottom molten bath, glass metal layering is serious, component lack of homogeneity, mainly for the production of to the not high low-grade opticglass of uniformity requirement and simple glass.Adopt the kiln of combustion gas and electric energy Hybrid Heating because controllability is good, adapt to that the trade mark is strong, stability outstanding and the advantage such as process debugging is simple; be widely used in the production of all kinds of environmental protection such as light crown, fluorine crown, heavy crown, barium crown, flint and dense flint or non-environmental protection high-quality opticglass, even can be used for producing the portioned product of lanthanide glass.
The melting pool working mechanism of this kiln is after admixtion forms glass metal, successively heat exchange is carried out in melting pool 2, gas in this heat exchanging process in glass metal is progressively discharged, density is corresponding increase also, be deposited on the glass metal of melting pool 2 bottom for fusing is abundant, gas content is few, therefore the outlet of melting pool glass metal is generally arranged on the sidepiece of bottom.In order to obtain high-quality glass, melting pool communicating pipe 8 can use platinum material usually, and waits the impact of factors by platinum price height, and platinum Diameter of connecting pipe is general all less, and sectional area is less than 1/20th of fusing bottom.The glass metal near the mouth of pipe is only had to be exported by communicating pipe in time under normal circumstances, the glass metal that such major part has melted is all trapped in the bottom of melting pool 2, cause melting pool inefficiency, as shown in Figure 1, melting pool 2 is provided with batch feeding mouth 1, melting pool communicating pipe 8, molten electrode, melting pool metal line 12 and combustion gas burning rifle heating system.If increase the flow velocity of melting pool communicating pipe 8, then the glass metal that melting pool 2 upper strata has not been melted completely can be made to be output, to cause the qualities such as product bubble, striped bad.Glass metal is long in melting pool 2 residence time in addition, also there will be the situation that the optical properties such as the degree of staining of product, homogeneity are deteriorated.
Secondly the glass metal of melting pool is in flow state always, therefore can not ensureing all to melt fully by entering settling pond glass metal communicating pipe, if this thing happens, can cause the quality abnormals such as product bubble, striped.Running into the way that Similar Problems often takes is increase temperature of fusion or reduce load, not only aggravate ageing equipment shorten kiln work-ing life as increased temperature of fusion, product degree of staining also can be caused to be deteriorated, even refractory corrosion enters the generation that glass metal produces the problems such as striped is bad, and reduces load and also reduce melting pool working efficiency simultaneously.
