Abstract
An optical glass is generally fused in a specially designed fusion vessel with high capacity. With the change of glass further processing in industry including as less as stock balance and as smaller as fusing lot, economical loss caused by using a fusion vessel with high capacity for a small fusion lot. The invention provides a fusion vessel for fusing an optical glass economically in a small fusion lot, mainly including a base assembly fusion reservoir (1) which having a small fusion volume in a range of 0.25 m<3>, and some accessory heat conductance assembly (2; 4, 5; 6, 7).
Description
Technical field
The present invention relates to a kind of melting tank that opticglass and short run fusion are used that is used to melt, wherein opticglass also comprises spectacle glass and tinted shade.
Background technology
As everyone knows, all be that fusing is used for traditional optical device, tinted shade and comprises contact lens and the filter glass lens that are used for glasses of the rare earth oxide glass of high refractive index in big melting tank for a long time.The capacity of melting pool is generally 1m
3Because the continuous variation of industrial glass deep processing, especially because the variation of order business, taking cost into account, trend towards keeping the quantity in stock of a fewer glassy product, this just often need carry out the melting process of short run, thereby gives to be in and use the technical field of big melting tank state to bring economic problems.
According to German utility model patent G8808773U1, can learn the smelting furnace of fusing amount substantially 80 to 300 liters little fusing amount.Yet they are not standard design.Also really there is same problem in the smelting furnace that another German utility model patent 6M7325804 discloses.
German Patent 1039714B discloses a kind of glass furnace that has the cooling duct of cool furnace inwall and disk shaped bottom wall.
Summary of the invention
The present invention is intended to solve the melting tank problem that fusing opticglass is used, and it will make the glass of this form of production both economical even short run also become possibility.
According to the present invention, a kind of melting tank that is used for fusion short run opticglass is provided, it is characterized in that this melting tank is a standard design, comprising: a basic module melting pool has the fusing amount at 0.25m
3Low fusing amount in the scope, it is made up of the bulk ceramics refractory materials that is positioned on the pedestal that is formed by the angle bearing, the ceramic refractory plate, be installed on the sidewall and diapire of melting pool, to form thermal insulation layer, with a housing unit, its along melting pool and and the ceramic refractory plate together, make the melting pool thermal isolation.
By measuring,,, can obtain the product of small serial production economically owing to its following advantage according to the present invention:
Whole fusion time and start time are short;
High yield;
Glass elasticity changes;
The simplicity of design cheapness;
Quantum of output economically.
According to tool example embodiment according to the present invention, if provide another one to be the termal conductor module of cooling system in form, just can prevent the corrosion of the melting tank made with ceramic refractory, improve its work-ing life.If for the piped cooling system is installed in the inside that is positioned at melting pool sidewall and diapire face housing unit on every side, the design advantage of this melting tank is embodied on its thermal conduction and the structure in form.
According to a specific embodiment of the present invention,,, just can provide the housing unit of the good heat conductivity of a simplicity of design such as silica glass if housing unit comprises that has been full of a ceramic refractory particulate metal shell.
Melting pool can electricity consumption and/or the used fossil oil heating of traditional heating mode.
Now will the present invention is described in detail in conjunction with the accompanying drawing of an embodiment of the present invention.
Description of drawings
The standard melting tank of the design according to the present invention has been shown in unique accompanying drawing.
Embodiment
This melting tank has a melting pool 1, and it is made up of known ceramic refractory, and multiple opticglass melts in melting pool.Quartz is a specific embodiment of this material.The fusion of melting pool 1 is 0.25m normally
3, just, it is much smaller than the fusing amount of known melting tank.
Melting pool 1 comprises the monolithic ceramic material of the basic module that forms melting tank.A fusion is arranged with exporting 1a at this monolithic ceramic assembly of tray-shaped bottom.
Melting pool can electricity consumption and/or the fossil oil heating used of known type of heating.For the sake of simplicity, hot spots does not illustrate in the drawings.
Another assembly of melting tank comprises the ceramic refractory plate, as quartz plate 2, forms a thermal insulation layer along melting pool.The bottom of ceramic refractory plate is positioned on the angle bearing 3, has formed the pedestal of this melting tank.
Melting tank is surrounded by metal cabinet 4, has filled the ceramic refractory particle in the metal box, and preferably silica glass particle 5, has formed a thermal insulation layer again like this between metal box body wall and ceramic fire resistant plate 2.The metal box that is full of has formed another assembly of melting tank.
The assembly with the thermal insulation material manufacturing of other structures is included in wherein equally.
The feature of said melting tank is to adopt standard design here.Whole melting tank comprises some precast segments, and they needn't make as before at the scene again like this, but produce in the workshop.
This melting tank can be built up at the use scene in a working days, therefore compares with standard level, and the shut-down period of this melting tank reduces above 50%.
Owing in the bottom surface and the side of melting pool cooling system is housed, the therefore feasible corrosion that reduces the used ceramic refractory of melting pool to prolong its work-ing life to greatest extent, is not compared with there being Cooling System Design, and its life-span can prolong 100%.
Owing to used the cooling melting tank of standard design, a little fusing amount melting tank that has the melt-through pond is compared with the situation of using big opticglass melting tank, makes the more multi-form undersized opticglass of more cost effective production become possibility.
