Description
Technical field
The present invention relates to a kind of coal flotation agents, belong to auxiliary chemicals technical field.
Background technique
Flotation coal separation method is on the basis of comprehensively considering the different characteristic of physicochemical properties of mineral surfaces to coal
A kind of coal preparation method that particle is sorted, and a kind of coal preparation method being widely used at present.Coal particles own face is all
There is hydrophobicitys, while after flotation agent is added, the hydrophobicity on coal surface can be also improved, and pass through each process, coal
Charcoal particle can float on the mine liquid surface of flotation device, and can be recycled in the form of foam.
The flotation agent that flotation coal separation is utilized plays an important role to coal separation effect, in traditional flotation coal preparation technique, fortune
Treating the coal grain in coal separation mud with collecting agent and grinding stone mud has different compatibility and selectivity, to form hydrophobic cleaned coal
With the tiny group of hydrophily coal slime, foaming agent then there is different floatings to take speed out of the cleaned coal of formation and the tiny group of coal slime
Rate, and then an opposite cleaned coal froth bed and coal slime layering are constantly formed in floating-upward process, finally successfully realize flotation point
From.Because flotation agent used in traditional technology uses plurality of raw materials classification storage and addition, equipment investment is big, technology is relatively multiple
It is miscellaneous, and each component is complex in the technology adjustment of flotation site, it is higher to the skill requirement of operator and random bigger than normal.
Summary of the invention
The object of the present invention is to provide a kind of novel coal flotation agent, solve traditional flotation agent need classification storage and
The drawbacks of addition, has the characteristics that flotation effect is good, disposable addition.
Coal flotation agent of the present invention is made of the raw material of following mass percent:
Collecting agent 60~75%, foaming agent 20~40%, complexing agent 1~5%.
Preferably, it is made of the raw material of following mass percent:
Collecting agent 70%, foaming agent 27%, complexing agent 3%.
Wherein:
The collecting agent is made of the raw material of following mass percent: triethyl phosphate 60~70%, diesel oil 20~30%,
Methylene chloride 10~20%, preferably triethyl phosphate 70%, diesel oil 20%, methylene chloride 10%；The addition of methylene chloride can
Enhance the mobility of flotation agent, so that the flow effect of flotation agent is more preferable, meanwhile, the density of triethyl phosphate is between diesel oil and two
Between chloromethanes, in floatation process, the mobility of molecule is reinforced, and enhances separating effect.
The foaming agent is the mixture of abienol and sodium lauryl sulfate, and abienol accounts for 80wt% in mixture, 12
Alcohol sodium sulphate accounts for 20%.
The complexing agent is the extremely strong graphene of adsorption capacity, and graphene adsorbent can adsorb the heavy metal object in coal
Matter reduces in the subsequent use process of coal and heavy metal pollution occurs.
Beneficial effects of the present invention are as follows:
(1) coal flotation agent of the invention disposably adds when in use, can be according to the composition of coal, appropriate adjustment
The dosage of flotation agent, and composition and ratio when using same coal is relatively stable, specific aim is good, avoids in conventional method point
The problem of classification is using one pack systems such as collecting agent, foaming agents also avoid blindness and randomness when addition proportion；
(2) coal flotation agent of the invention is high to the selectivity of coal, and usage amount is more saved, and can be recycled.
Specific embodiment
The present invention is described further with reference to embodiments.
Embodiment 1
Coal flotation agent is made of the raw material of following mass percent:
Collecting agent 70%, foaming agent 27%, graphene 3%.Wherein:
Collecting agent is made of the raw material of following mass percent: triethyl phosphate 70%, diesel oil 27%, methylene chloride 3%；
Foaming agent is made of 80wt% abienol and 20wt% sodium lauryl sulfate.
Preparation method is to mix the raw material of proportional quantity at room temperature.
The coal flotation agent that the present embodiment is obtained screens dross coal, and actual effect is good.
