Abstract
A kind of with the method for useless quartz crucible for raw material production melting obtuse angle quartz sand, it uses raw material to comprise: hydrofluoric acid, water that the dilute hydrochloric acid solution that useless quartz crucible material, concentration are 11%-14%, concentration are 46.5%, production method utilization of waste material in the present invention, create larger economic benefit, and equipment used is few, simple to operate, less investment, non-environmental-pollution.
Description
[technical field]
Originally the invention belongs to natural stone diamond stone manufacture field, espespecially a kind of with the method for useless quartz crucible for raw material production melting obtuse angle quartz sand.
[background technology]
Crucible is with the made vessel of fire-resistant material or melting pot, when there being solid will heat with big fire, just must use crucible.Crucible can be divided into by the starting material made, plumbago crucible, quartz crucible, porcelain crucible, corundum crucible, silicon carbide crucible, platinum crucible, nickel crucible.Quartz crucible is an important kind of crucible, can use, have high purity, temperature tolerance is strong, size is large, precision is high, the advantage such as good heat preservation performance, save energy, steady quality below 1450 DEG C.
[summary of the invention]
The object of the present invention is to provide a kind of with the method for useless quartz crucible for raw material production melting obtuse angle quartz sand.
To achieve these goals, the present invention is a kind of with the method for useless quartz crucible for raw material production melting obtuse angle quartz sand, and it uses raw material to comprise: hydrofluoric acid, water that the dilute hydrochloric acid that useless quartz crucible material, concentration are 11%-14%, concentration are 46.5%:
A. crusher sent into by the quartz crucible material that will give up, and making it be split into granularity is particulate state;
B. the useless quartz crucible particle after division is sent into sour pond, concentration is the dilute hydrochloric acid of 11%-14% and concentration by the ratio in 4: 1 is soak 73-75 hour after the hydrofluoric acid mixing of 46.5%, after pulling the useless quartz crucible particle in sour pond after mixing acid immersion out, send into rinsing machine use water immediately and rinse deacidification;
C. the useless quartz crucible particle after deacidification is sent into high temperature sintering furnace, adjust in-furnace temperature to be 1850 DEG C-1920 DEG C, fusing time is 12-14 hour, obtains crucible material molten mass.
D. melting terminates rear stopping and powering to high temperature sintering furnace, obtains the solid melting crucible material of bulk after being cooled to normal temperature cooling;
E. uses the solid melting crucible material of mechanical shock bulk, after making it become fritter, send into crusher in crushing, then melting obtuse angle quartz sand sends into magnetic separator, under the effect of magnetic separator internal magnetic field, Adsorption containing magnetic, quartz sand containing metal, finally obtain finished product.
Compared with prior art, the present invention has following beneficial effect: the method utilization of waste material, creates larger economic benefit, and equipment used is few, simple to operate, less investment, non-environmental-pollution
[embodiment]
With the method for useless quartz crucible for raw material production melting obtuse angle quartz sand, gas production stage is as follows:
A. crusher sent into by the quartz crucible material that will give up, and making it be split into granularity is particulate state;
B. the useless quartz crucible particle after division is sent into sour pond, concentration is the dilute hydrochloric acid of 11%-14% and concentration by the ratio in 4: 1 is soak 73-75 hour after the hydrofluoric acid mixing of 46.5%, after pulling the useless quartz crucible particle in sour pond after mixing acid immersion out, send into rinsing machine use water immediately and rinse deacidification;
C. the useless quartz crucible particle after deacidification is sent into high temperature sintering furnace, adjust in-furnace temperature to be 1850 DEG C-1920 DEG C, fusing time is 12-14 hour, obtains crucible material molten mass.
D. melting terminates rear stopping and powering to high temperature sintering furnace, obtains the solid melting crucible material of bulk after being cooled to normal temperature cooling;
E. uses the solid melting crucible material of mechanical shock bulk, after making it become fritter, send into crusher in crushing, then melting obtuse angle quartz sand sends into magnetic separator, under the effect of magnetic separator internal magnetic field, Adsorption containing magnetic, quartz sand containing metal, finally obtain finished product.
Provide a kind of with the method for useless quartz crucible for primary industryization production crucible melting obtuse angle quartz sand in the present invention, the method utilization of waste material, creates larger economic benefit, and equipment used is few, simple to operate, less investment, non-environmental-pollution.
