Abstract
The invention provides a purification method of diatomite. The method comprises procedures of raw ore crushing, screening, pulping, separation, rinsing, centrifugal spin-drying and drying. The diatomite prepared with the method is high in grade, pure and wide in application range and contains few impurities, and the method is applicable to production of the pure diatomite.
Description
Technical field
The present invention is to provide a kind of Purification of Diatomite method of building materials and chemical industry and food processing field.
Background technology
Diatomite is diatom fossils weathered material in time immemorial, is widely used at building materials and chemical industry and food processing field.Usual diatomite is earthy discrete particles, deposits existence in mineral deposit mode, mineralizing process it, be mixed with the mineral materials such as sandstone, montmorillonite and illite, exist as impurity.Obtain clean diatomite, just need to remove the impurity be mixed with in diatomite.The method of usual employing hand picking, or the method that water conservancy is separated, but also can be mixed with impurity in the diatomite processed, therefore from grade, desirable technical requirements and quality can not be reached.
Summary of the invention
In order to by diatomite purifying, the present invention proposes a kind of Purification of Diatomite method.The method is by raw ore pulverizing, screening, slurrying, separation, rinsing, centrifuge dripping and baking operation.Solve the technical problem of Purification of Diatomite.
The scheme that technical solution problem of the present invention adopts is:
1, raw ore is pulverized: be crushed into Powdered by pulverizer by diatomite original ore.
2, sieve: pulverous diatomite is sieved through vibratory screening apparatus, abandons macrobead, form diatomite powder mix.
3, slurrying: be placed in pond by diatomite powder mix, adds water 5 times, is added with the hydrochloric acid of 1%, stirs simultaneously in water, after stirring, leaves standstill 30 minutes.
4, be separated: incline and upper strata bentonite slurry, take out middle level diatomite mud, abandon lower sediment thing.
5, rinsing: after separation circuit completes, continues in pond, add the water containing tensio-active agent, tensio-active agent add-on 1%, after stirring, settlement treatment 30 minutes.
6, centrifuge dripping: the diatom soil paste through rinsing is joined in whizzer, throws away attached water.
7, drying: the diatomite through drying is put in dryer, drying, then taking out from dryer, pack after naturally cooling, become finished product purified silicious earth.
Positively effect, the diatomite prepared by the inventive method is of high grade, and impurity is few, pure, wide application.Suitable to producing the application of pure diatomite.
Embodiment
1, raw ore is pulverized: be crushed into Powdered by pulverizer by diatomite original ore.
2, sieve: pulverous diatomite is sieved through vibratory screening apparatus, abandons macrobead, form diatomite powder mix.
3, slurrying: be placed in pond by diatomite powder mix, adds water 5 times, is added with the hydrochloric acid of 1%, stirs simultaneously in water, after stirring, leaves standstill 30 minutes.
4, be separated: incline and upper strata bentonite slurry, take out middle level diatomite mud, abandon lower sediment thing.
5, rinsing: after separation circuit completes, continues in pond, add the water containing tensio-active agent, tensio-active agent add-on 1%, after stirring, settlement treatment 30 minutes.
6, centrifuge dripping: the diatom soil paste through rinsing is joined in whizzer, throws away attached water.
7, drying: the diatomite through drying is put in dryer, drying, then taking out from dryer, pack after naturally cooling, become finished product purified silicious earth.
Know-why:
In pulping process, add hydrochloric acid water, the neutralization of alkaline matter can be conducive to, make impurity be easy to be separated.
In rinsing process, add tensio-active agent, diatomite can be made to clean, be conducive to being separated.
Because diatomite is different from other impurity proportion, so disperseed in water by the diatomite containing impurity, easily produce layering, thus discard impurity, retain diatomite layer slurry, be conducive to the physical sepn of diatomite and impurity.
Diatomite quality through purifying is clean, and color is pure white, good dispersity, is beneficial to application.
