Abstract
The present invention provides a kind of lithium bentonite preparation process, pass through first lithiumation and secondary lithiumation, it is aided with the technique of heating, so that bentonite is lithiated agent and be modified, simple process, the lithium bentonite better performances prepared, and in secondary lithiumation, bentonite is wrapped up by separation layer, promotes bentonitic lithiumation modified effect, working efficiency is improved, processing cost is reduced.
Description
Technical field
The present invention relates to bentonite manufacturing field more particularly to a kind of lithium bentonite preparation processes.
Background technique
At present when manufacturing to lithium bentonite, usually used is two kinds of method of modifying of dry and wet, still
In the preparation, the lithium bentonite lithiumation performance prepared is not strong by current preparation process, and needs when modified using big
The water of amount is more artificial, to be monitored to modified bentonite, completes modified work, working efficiency is lower.Cause
This, solves the problems, such as that lithium bentonite preparation process lithiumation performance is particularly important without strong and is inefficient.
Summary of the invention
In view of the above-mentioned problems of the prior art, the object of the present invention is to provide a kind of lithium bentonite preparation process,
By first lithiumation and secondary lithiumation, the technique for being aided with heating, being lithiated bentonite, agent is modified, and simple process is prepared
Lithium bentonite better performances solve the problems, such as that lithium bentonite preparation process lithiumation performance is not strong and inefficient.
The present invention provides a kind of lithium bentonite preparation process, and the preparation process is as follows:
Step 1: bentonite material mined in bentonite ore is screened, and is removed impurity, is obtained bentonite origin
Material；
Step 2: it is milled collecting to be sent into pulverizer mill after 24 ~ 36h of bentonite origin material sunning；
Step 3: lithiumation agent is added into the bentonite material after milling, and the raw material that lithiumation agent is added is stirred
It mixes；
Step 4: the raw material stirred evenly is evenly laid out, and Hot-blast Heating is carried out to it；
Step 5: by the bentonite surface after heating uniformly sprinkling one layer of lithiumation agent, and lithiumation agent surface covering every
Absciss layer, and reheating is carried out to it；
Step 6: being sent into packing apparatus after the bentonite after reheating is risen again naturally and pack, and completes preparation.
Further improvement lies in that: when using Hot-blast Heating in the step 4, bentonitic temperature is no more than 75 DEG C, hot wind
Heating time is 48 ~ 72h.
Further improvement lies in that: separation layer in the step 5 is transparent membrane, the temperature of the reheating is 50 ~
65℃。
Further improvement lies in that: the lithiumation agent is one of lithium carbonate or lithium sulfate.
The beneficial effects of the present invention are: by first lithiumation and secondary lithiumation, the technique for being aided with heating makes bentonite by lithium
Agent is modified, simple process, the lithium bentonite better performances prepared, and in secondary lithiumation, by separation layer to swollen
Profit soil is wrapped up, and bentonitic lithiumation modified effect is promoted, and improves working efficiency, reduces processing cost.
