Abstract
The utility model provides a can improve the agitator of optical glass homogeneity. Stirrer for producing optical glass comprises puddler and paddle, the mode setting that the paddle rises with the spiral around the puddler, just the paddle is a full wafer paddle. The utility model discloses a full wafer paddle that mode that agitator owing to have rises with the spiral around the puddler set up rolls about the homogenization in -process can fine formation from top to bottom to can realize the homogenization of glass liquid well. The utility model discloses an improvement of the big viscosity optical glass homogeneity of agitator specially adapted.
Description
Technical field
The utility model relates to a kind of agitator, particularly a kind of agitator that can improve large viscosity optical glass homogeneity.
Background technology
The spatially uniform of optical glass material specific refractory power is one of its most important character.Glass cord is the spatially change among a small circle of glass homogeneity, and variation range is approximately 0.1mm to 2mm, and in refractive index spatial, large-scale overall homogeneity then covers monolithic glass.
The major cause causing glass material heterogeneity to produce is the melting technology that opticglass adopts, the unrealized completely even and parting furnace wall material of starting material in fusion process, convection current in tank furnace and settling pond creates the homogeneity in fusion process, and the hybrid technique in discharging process further increases homogeneity.
At present, the common method improving glass homogeneity is agitated pool melten glass being passed be positioned at the vertical orientation in melting device downstream, agitator is provided with in agitated pool, agitator has the central shaft by revolution, multiple blade extends out from central shaft, for being mixed by melten glass when melten glass passes from the top of agitated pool to bottom.Existing agitator structure to large viscosity glass homogenizing mainly formed be horizontal direction glass fluid flowing, homo-effect is bad.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of agitator that can improve optical glass homogeneity.
The technical scheme that the utility model technical solution problem adopts is: opticglass production agitator, is made up of agitator arm and blade, and described blade is arranged around agitator arm in spiralling mode, and described blade is whole piece blade.
Further, described agitator arm rotarily drives blade rotation by driving.
Further, described agitator arm and blade adopt platinum or platinum alloy to make.
Further, described agitator arm and blade adopt the platinum of dispersion reinforcing or platinum alloy to make.
The beneficial effects of the utility model are: agitator of the present utility model, owing to having the full wafer blade arranged in spiralling mode around agitator arm, can be formed very well and roll up and down, thus can realize the homogenizing of glass metal well in homogenization process.Agitator of the present utility model is specially adapted to the improvement of large viscosity optical glass homogeneity.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is utility model works view.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, agitator of the present utility model is made up of agitator arm 3 and blade 4, and blade 4 is arranged around agitator arm 3 in spiralling mode, and blade 4 is whole piece blades.Rotarily drive blade 4 by driving agitator arm 3 to rotate.
Agitator arm 3 and blade 4 preferably adopt platinum or platinum alloy to make, or adopt the platinum of dispersion reinforcing or platinum alloy (platinum alloy of such as zirconia rigidizer) to make.
During work, agitator of the present utility model is put into the agitated pool 1 with discharge nozzle 7, after glass metal 5 is full of agitated pool 1, agitator is rotated by suitable driving mechanism.Such as, agitator is rotated by electric motor by geartransmission.Drive glass metal 5 rises along blade 4 by the blade 4 of agitator, then from agitated pool 1 edge decline, thus in agitated pool 1 up and down rolling reach homo-effect, optical glass homogeneity can be improved significantly, as shown in Figure 3.Glass metal 5 is completed homogenizing and is flowed out by discharge nozzle 7 in agitated pool 1.
Agitator of the present utility model is owing to having the full wafer blade 4 arranged in spiralling mode around agitator arm 3, and not multiple blade is extended, therefore, can be formed very well in homogenization process and roll up and down, thus the homogenizing of glass metal can be realized well.Device of the present utility model can be used for the improvement of the homogeneity of opticglass, but is specially adapted to the improvement of large viscosity optical glass homogeneity.
