Abstract
The semi-continuous phosphate glass smelter includes a main smelting furnace with a heater and a platinum crucible and one or two pre-smelting furnaces with a heater and a pre-smelting crucible over the main smelting furnace. There are material flowing pipes communicating from the bottom of the pre-smelting crucible to the platinum crucible in the main smelting furnace. Raw material is presmelted in presmelting crucible and the melt after pre-smelting flows via the material flowing pipe to platinum crucible for further smelting before in jection to form. The double-crucible semi-continuous smelting process is saving in heat energy, less damage of pre-smelting crucible, less raw material loss, less steps and high efficiency.
Description
The present invention is a kind of device of semicontinuous phosphate glass smelter.
In order to produce the phosphate glass of high quality, high rate of finished products, need melting in platinum crucible.But,, can damage platinum crucible if raw material (industrial chemicals admixtion) are directly added; And adopt glass grog (glass cullet), then harmless to platinum crucible.Therefore adopt usually and separate phosphate glass smelter twice.At first in the fritting crucible 1 of quartz with the raw material presmelting after, from quartz crucible, glass melt is watered out, become the glass grog through selecting to clean, add band top cover 2 then and stir in the platinum crucible 4 that blocks leaf oar 3 and leak injection forming after the melting, as shown in Figure 1.This kind device shortcoming is: 1) in the cast glass process, quartz crucible 1 passes in and out smelting furnace repeatedly, impacted by rapid heat cycle, bursts easily, and causes heat to scatter and disappear, and workman's operational condition is poor.2) cold glass grog needs fusing once more in platinum crucible 4, not only increased energy waste but also prolonged the time of melting in platinum crucible; 3) the glass grog need be through selecting, and raw material availability is low, and easily contaminated; 4) operation is many, and efficiency is low.
Purpose of the present invention is in order to overcome the problem in the technology formerly, a kind of device of semicontinuous phosphate glass smelter is provided, after the raw material presmelting, need not in the fritting crucible, water out, can directly inject in the platinum crucible, will both save the fritting crucible by liquid, save heat energy again, avoid material loss, reduce operation, raise labour efficiency.
The inventive system comprises: contain main furnace heats body 11 and the main smelting furnace 10 that places the platinum crucible 4 that has top cover 2 and paddle oar 3 in the main furnace heats body 11, contain premelt furnace heating member 8 and the premelt furnace 7 that places the fritting crucible 1 in the premelt furnace heating member 8.
Have one or two premelt furnace 7 to place the top of main smelting furnace 11, the bottom of the fritting crucible 1 in the premelt furnace 7 has stream material pipe 9 to lead on the top of the platinum crucible 4 in the main smelting furnace 10.As Fig. 2, shown in Figure 3.
Said fritting crucible 1 is by pottery, or quartzy, or corundum, or other high-temperature oxides constitute.
Said stream material pipe 9 mainly is to be surrounded by lagging material by platinotron with outside platinotron to constitute.
Said premelt furnace 7 is built in can activity to hang on the top of the fritting crucible 1 in the premelt furnace heating member 8 cover 5 and feed the interior ventpipe 6 of fritting crucible 1.When needs with fritting crucible 1 sealing, when in fritting crucible 1, sending into needed gas, just activity is hung and covers 5 and put down, cover tight fritting crucible 1.When not required, activity can be hung and cover 5 and sling, need not cover fritting crucible 1.It is also passable that lid is hung in the activity that perhaps do not need.
Device of the present invention as mentioned above, at first will need the batching of the industrial chemicals that is called raw material of the phosphate glass of melting to drop into the 1 internal heating presmelting of fritting crucible after, melt directly flows in the platinum crucible 4 through overcurrent material pipe 9, continues melting, leaks injection forming then.
Advantage of the present invention is: 4 liang of crucible inner chambers of fritting crucible 1 and platinum crucible are communicated with by stream material pipe 9.So after in the fritting crucible, finishing reinforced, presmelting, through overcurrent material pipe glass melt is directly irritated in the platinum crucible and continues melting, leak injection forming then.In the platinum crucible melting, reinforced, the presmelting of another crucible glass in the fritting crucible, have been finished.After platinum crucible is finished Lou injection forming, glass melt in the fritting crucible can be poured into and continue melting in the platinum crucible, two kinds of crucible relay-type meltings simultaneously are called semicontinuous melting.Overcome the shortcoming that twice is separated melting in the technology formerly.The work-ing life of considering the fritting crucible is limited, needs often to change, and then can be used by turns by two premelt furnace, is equipped with two premelt furnace 7 exactly above main smelting furnace 10.As Fig. 3.
The present invention is applicable to the functional glass of the various particular varieties of melting.The common feature of these kind glass is: raw material can not directly be added avoid damaging platinum crucible in the platinum crucible, be to add the platinum crucible melting with the glass grog.The functional glass of for example various adulterated phosphate laser glasses, phosphate optical glass, phosphoric acid salt functional glass, plumbiferous functional glass and other particular varieties.Although the glass of these kinds is theoretically, the continuous or semicontinuous melting that the tank furnace that can build by laying bricks or stones with refractory materials and platinum crucible constitute.But if in batches little, produce uneconomically with tank furnace, so formerly adopt the ceramic crucible presmelting in the technology, be the device that ceramic crucible and platinum crucible separate melting for twice, there is above-mentioned shortcoming in it.The of the present invention pair of semicontinuous smelting apparatus of crucible is suitable for that production lot is not too big most, this type of laser of many kinds and optical function glass.When changing the production kind, only need change the fritting crucible, simultaneously platinum crucible be got final product with the scorification cleaning.Should be noted that with the different types of glass of device melting of the present invention, be according to the effect of the temperature of fusion of glass and glass melt to crucible material, select suitable fritting crucible material, as above-mentioned pottery, or quartzy, or corundum, or the material of other high-temperature oxides.
In a word, as mentioned above, use device of the present invention and directly continue melting to platinum crucible by the glass melt in the fritting crucible, removed the damage factor of fritting crucible, removed formerly in the technology entering platinum crucible again, the calorific loss that twice fusing caused after outpouring in the fritting crucible from because of rapid heat cycle, both saved heat energy, avoid the loss of raw material again, both reduced operation, improved efficient again.
