Description
Technical field
The utility model relates to the purification apparatus before the smelting of a kind of tungsten ore raw material, particularly the suite of equipment of the assorted tungsten wolframic acid sodium of a kind of purifying treatment height.
In the specification, term " high assorted tungsten wolframic acid sodium " refers to the sodium wolframate of non-employing sodium hydroxide, sodium hydroxide solution or soda decomposition gained.
Term " high assorted tungsten ratio " refers to that the ratio of impurity and tungsten is high.
Term " before handing over liquid " refers to the original solution of ion exchange column adsorption operation.
Background technology
Tungsten is a kind of non-ferrous metal of infusibility, is also a kind of important strategic resource, is used widely because it has the premium propertiess such as fusing point is high, hardness is large, ductility is strong, wear-resisting and corrosion-resistant.
Along with tungsten ore raw material is low to main grade, impurity height future development, each company reclaims in different ways, Decomposition of Tungsten, causes market is taken as the leading factor with height tungsten wolframic acid sodium/tungsten ore of mixing.Tungsten smelting is main flow at present with ion exchange method, and the maximum feature of ion-exchange is exactly have strict requirement to the foreign matter content of liquid before handing over, so must carry out purifying treatment to height tungsten wolframic acid sodium of mixing before exchange.
Summary of the invention
The purpose of this utility model is to provide the suite of equipment of the assorted tungsten wolframic acid sodium of a kind of purifying treatment height, with foreign matter content in the original solution reducing Tungsten smelting technological process ion exchange column adsorption operation, obtains liquid before qualified friendship.
The technical solution of the utility model is: the suite of equipment of the assorted tungsten wolframic acid sodium of a kind of purifying treatment height, comprise: disintegrating apparatus is connected with stirring mixing vessels by chute, the stirring mixing vessels being provided with agitator motor is communicated with reactor through solution pump by pipeline, and reactor is communicated with filter by pipeline.
Described disintegrating apparatus, preferred spheres grinding machine.
The upper end of described stirring mixing vessels is installed by the water inlet pipe of solenoid control.
Described reactor is provided with electric heater unit.
The beneficial effects of the utility model are: by suite of equipment purifying treatment tungsten ore raw material described in the utility model, the metal ion in high assorted tungsten wolframic acid sodium in content negatively charged ion and tungsten ore can be impelled to react, the material generating solubility product little enters filter-press residues, the height be purified is mixed the sodium wolframate of tungsten ratio, reduce foreign matter content in the original solution of Tungsten smelting technological process ion exchange column adsorption operation, obtain liquid before qualified friendship.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is originally the suite of equipment combination schematic diagram of the assorted tungsten wolframic acid sodium of a kind of purifying treatment height.
