Description
Technical field
The present invention relates to thick barium, strontium leaching technologies field, more particularly to the leaching device of a kind of improved thick barium, strontium and its
Leaching technology.
Background technology
Celestine and feed coal carry out reduction roasting under the high temperature conditions, and the SrSO4 in ore is reduced into solubility
Rough SrS, referred to as thick strontium.The blanking of discharge outlet is transported to leaching groove with leaching the leaching liquid of groove by us using forklift（Come
From the water of three-level settling tank）React：
2SrS + 2H2O — >Sr(HS)2 + Sr(OH)2
Needed water during leaching（It is high from settling tank, temperature）Divide three times and be passed through in the leaching groove equipped with thick strontium.Produced after reaction
Saltwater brine, it is transported to after the saltwater brine mixing of first time and second time except barium tank, dense halogen is driven into settling tank clarification 2.5h. after removing barium
It is re-fed into follow-up carbonization workshop section.Dilute halogen of the 3rd time is because concentration is inadequate, by first time leaching liquid as next leaching cycle
Use, whole process 10-20 hours.
This technics comparing is time-consuming, and thick strontium needs to repeat three times leaching operations in groove is leached.Worker's working strength also compares
Larger, efficiency is low, conversion ratio is low, it is necessary to which worker is shoveled waste residue onto conveyer belt with spade when waste residue goes out groove.
The content of the invention
The invention provides a kind of improved thick barium, the leaching device and its leaching technology of strontium, leaching effect is good, conversion ratio
Height, the time is short, and in the confined reaction tank of temperature-pressure, agitated, substance reaction is abundant, high conversion rate.Waste residue is through centrifuge
After drying, water content is low, and the useful solution overwhelming majority is collected, and reduces the waste of material, and waste residue due to water content it is few,
It it also avoid strontium hydroxide and strontium sulfate be carried away with waste residue, pollution sources are not produced to environment.
In order to solve the above technical problems, the invention provides a kind of improved thick barium, the leaching device of strontium, including revolution
Stove, described revolution furnace bottom are provided with feed opening, and the blanking at feed opening transports leaching can, described leaching by chain mat machine
Tank is closed system, is internally provided with stirrer paddle, and described stirrer paddle is driven by being arranged on the motor at the top of leaching can,
Described leaching can is provided with solidliquid mixture liquid outlet, and described liquid outlet passes through pipeline communication to centrifuge, the bottom of centrifuge
Portion is provided with purified liquor outlet and solid formation exports.
A kind of improved thick barium, the leaching technology of strontium of the present invention, comprise the following steps：Rotary furnace is burnt thick
Barium, strontium material deliver to leaching can, and during work, leaching can is closed system, and thick barium, strontium material are added into the leaching can equipped with water, leaching
Temperature-pressure in tank, thick barium, strontium material and water react, stirrer paddle stirring 5-50 minutes, and solidliquid mixture is straight in leaching can
Tap into centrifuge, separated through centrifuge, useful solution is collected, and waste residue is discharged.
The one or more technical schemes provided in the embodiment of the present application, have at least the following technical effects or advantages：
During energy-saving, leaching effect it is good, in the confined reaction tank of temperature-pressure, agitated, substance reaction is abundant, conversion ratio
It is high.For waste residue after centrifuge dries, water content is low, and the useful solution overwhelming majority is collected, and reduces the waste of material, and is given up
Slag it also avoid strontium hydroxide and strontium sulfate be carried away with waste residue because water content is few, environmentally safe.
