Abstract

The utility model provides a device capable of continuous production of fluo phosphate optical glass, which comprises a melting vessel and a working vessel which is provided with an agitator and a material leakage tube. Furthermore, an oxidation vessel and a clarification vessel are orderly arranged between the melting vessel and the working vessel, while all the vessels are connected by connecting pipes and a temperature regulating vessel can also be arranged between the clarification vessel and the working vessel. With the device of the utility model, raw materials can be directly fed into the melting vessel for smelting, and then flows across the combustion vessel, the clarification vessel, the temperature regulating vessel and the working vessel, and finally be molded by leaking and pouring from the material leakage tube, and as a result, the continuous production of the fluo phosphate optical glass is realized. In addition, because every vessel of the utility model adopts a sealed structure, the heat energy dissipation as well as the volatilization of the raw material can be prevented, and as a result, the utility model plays the role of saving.

Description

Produce the device of fluorophosphate optical glass

Technical field

The utility model relates to a kind of device of producing opticglass, particularly relates to a kind of device of producing fluorophosphate optical glass.

Background technology

Fluorphosphate glass is the relative dispersion opticglass bigger than general crown glass of a kind of low chromatic dispersion, low refraction, shortwave direction, can be used as the opticglass of the especial dispersion of eliminating secondary spectrum, has lower softening temperature, higher fluorescence intensity, it can make non-spherical lens through secondary press, is the good optical material of producing digital product.But the fluorphosphate glass component volatilization is serious in its fusion process, and the quality of product is (as bubble, impurity, striped, N _d, V _d) restive, and it is serious to produce a large amount of dust acid mist environmental pollutions, so found very difficulty.

At present, the device that is used to produce fluorophosphate optical glass mainly contains following several: CN2457148 provides a kind of semicontinuous smelting apparatus, after raw material are dropped into the presmelting of fritting crucible internal heating, melt directly carries out melting in overcurrent material pipe flows into the platinum crucible of being with top cover and paddle slurry, leak injection forming then.But this device is owing to being a kind of semicontinuous melting mode, so be not suitable for producing in enormous quantities.CN1339411A provides two kinds of devices, all is to make it to melt the device that obtains melten glass by loading frit and heating.A kind of device has as the container of the molten glass raw material of substrate, melten glass is supplied with the supplying opening of oxidizing gas and is positioned at the raw material load port of oxidizing gas supplying opening top in container.Another kind of device has container, heating and the molten glass raw material as substrate and retains the raw material load port of the melten glass of gained, connection and contacting container, supplies with the supplying opening of dry environment gas and discharge environment gas purging mouth.But these two kinds of devices all are melting raw materials equipment, are not a complete set of equipment that fluorophosphate optical glass is founded.

The utility model content

Technical problem to be solved in the utility model provides a kind of device that can the continuous production fluorophosphate optical glass.

The technical scheme that the utility model technical solution problem is adopted is: the device of producing fluorophosphate optical glass, comprise melting vessel and contain agitator and the job container of leakage material pipe, between melting vessel and job container, also be disposed with oxidation container and clarification container, all have pipe connecting to connect between the described container.

Further, between clarification container and job container, also has tempering container.

The beneficial effects of the utility model are: raw material are directly added melting in the melting vessel, and the oxidation container of flowing through then, clarification container, tempering container and job container leak injection forming by leaking the material pipe at last, have realized the continuous production of fluorophosphate optical glass.In addition, each container of the present utility model all adopts closed structure, can avoid heat energy dissipation like this, can avoid volatility of raw material again, has played the effect of saving.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Embodiment

The utility model will be further described below in conjunction with accompanying drawing.

As shown in Figure 1, device of the present utility model comprises successively: melting vessel 1, oxidation container 3, clarification container 4, contain agitator 6 and leak the job container 8 of material pipe 7, all have pipe connecting 10 that each container is linked together between container and the container.

In order to make quality product better, between clarification container 4 and job container 8, also can add tempering container 5.For fear of heat energy dissipation and volatility of raw material, all containers are provided with lid, make each container be closed structure.In order to keep the oxidizing atmosphere of glass melt, help removing platinum grain inclusion and moisture content in the melt, on melting vessel 1 or oxidation container 3, also bubbling pipe 2 can be set, bubbling pipe 2 directly passes the lid of container and extend in the glass melt of container, and bubbling pipe 2 is preferably disposed on the melting vessel 1.For each container is not corroded, and after preventing that glass metal from evaporateing on lid or the wall, overheap and drop and in glass metal, influence glass quality, all containers are provided with ventpipe 9 and pass the lid of each container and extend in each container, but do not extend in the glass melt of container, but when on melting vessel 1, bubbling pipe 2 being set, ventpipe 9 just is set no longer on the melting vessel 1, and when on oxidation container 3, bubbling pipe 2 being set, ventpipe 9 just is set no longer on the oxidation container 3.In Fig. 1, bubbling pipe 2 is set on the melting vessel 1, ventpipe 9 is set on the oxidation container 3.

In actual production process, after at first raw material being dropped into the fusing of melting vessel 1 internal heating, melt carries out the oxidation dehydration in pipe connecting 10 enters oxidation container 3, melt enters in the clarification container 4 through pipe connecting 10 and clarifies then, enter adjusting melt temperature in the tempering container 5 through pipe connecting 10 after the clarification,, leak injection formings after leak material pipe 7, realized the continuous production of fluorophosphate optical glass by agitator 6 stir process after pipe connecting 10 enters in the job container 8.

Device of the present utility model preferably adopts the platinum material, issuable pollution when avoiding melting, the quality of assurance product.
