Abstract
The utility model discloses a purifying device for indium electrolytic waste liquid. The utility model aims to provide the purifying device for the indium electrolytic waste liquid. The purifying device for the indium electrolytic waste liquid comprises a stirring tank, and is characterized in that: the stirring tank is communicated with a liquid-storing tank through a pump, a stirrer in the stirring tank is connected with an electric screen cabinet through a speed regulating motor, and the bottom of the stirring tank is also communicated with a settling pool through a valve. A precision pH meter is also installed at one side of the stirring tank. The purifying device is mainly used for purifying the indium electrolytic waste liquid.
Description
Technical field
The utility model relates to a kind of refining plant, relates in particular to a kind of refining plant of indium electrolysis waste solution.
Background technology
Indium is strong because of its light perviousness and electroconductibility, is mainly used in to produce ITO target (being used to produce liquid-crystal display and flat screens), and this purposes is the main consumer field of indium, accounts for 70% of global indium consumption.The several consumer fields of next are respectively: the electronic semi-conductor field accounts for 12% of global consumption; Scolder and alloy field account for 12%; The research industry accounts for 6%.In the application of indium, its purity all requires more than 99.995%, and impurity elements such as cadmium and thallium all require below 0.0005%.
The process that is purified to 99.99% indium from 98% thick indium mainly is electrolysis, and the foreign matter content of electrolytic solution is the key whether electrolytic process can the output qualified product.Because contained impurity element such as Cd, Tl, the Sn etc. of anode accumulate in electrolytic solution easily in the thick indium electrolytic process, cause electrolysis cathode precipitate foreign matter content high and cause product defective.Existing method is that electrolytic solution that foreign matter content is high is discarded, prepares new electrolytic solution again, and it is long and expense is high to prepare new electrolytic solution required time.
Summary of the invention
The purpose of this utility model is to provide a kind of refining plant of indium electrolysis waste solution, so that with the regeneration after abstraction impurity removal is handled of indium electrolysis waste solution, and extraction agent can be recycled after back extraction regeneration.
For achieving the above object, technical solution of the present utility model is: a kind of refining plant of indium electrolysis waste solution, comprise steel basin, it is characterized in that: described steel basin 6 is communicated with reservoir 1 by pump 3, agitators 7 in the steel basin 6 are connected with electric screen cabinet 2 by buncher 4, the bottom of steel basin 6 also by valve 8 with leave standstill pond 9 and be communicated with.
One side of described steel basin 6 also is equipped with accurate PH meter 10.
The beneficial effects of the utility model are: with TBP (tributylphosphine) and aviation kerosene mixed extractant the indium electrolysis waste solution is carried out extraction treatment by adopting N235 (trioctylamine or claim three octyl tertiary amines), making impurity in the indium electrolysis waste solution such as Cd, Tl, Sn etc. all be extracted removes, electrolytic solution is able to regeneration, and extraction agent also can recycle after by back extraction.The utility model apparatus processing is simple, and energy consumption is low, and the foreign matter content of extraction back electrolytic solution is low, and the indium loss is little in the electrolytic solution.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure: the 1-reservoir, the 2-electric screen cabinet, the 3-pump, the 4-buncher, the 5-step-down gear, the 6-steel basin, the 7-agitator, the 8-valve, 9-leaves standstill the pond, the accurate PH meter of 10-.
Embodiment
Below in conjunction with accompanying drawing the utility model and embodiment thereof are described in further detail.
Referring to accompanying drawing, the utility model comprises steel basin, it is characterized in that: described steel basin 6 is communicated with reservoir 1 by pump 3, and steel basin 6 interior agitators 7 pass through buncher 4 and are connected with electric screen cabinet 2, the bottom of steel basin 6 also by valve 8 with leave standstill pond 9 and be communicated with.
One side of described steel basin 6 also is equipped with accurate PH meter 10.
With N235 (trioctylamine claims three octyl tertiary amines again) and the volume ratio mixing of TBP (tributylphosphine), make mixture by 100: 1; This mixture and aviation kerosene are pressed 1: 3 volume ratio mixing, make mixed extractant; This mixed extractant is put into steel basin 6, clean 2 times, and the adjustment pH value is 2 with distilled water; The indium electrolysis waste solution is pumped into the steel basin 6 from reservoir 1, starting agitator 7 (2 rev/mins) stirs extraction and puts into after 45 minutes and leave standstill pond 9, left standstill 30 minutes, layering appears, impurity Cd, Tl, Sn etc. are extracted to the upper strata, electrolytic solution behind the extracting and purifying is emitted from the bottom that leaves standstill pond 9, is the electrolytic solution of purifying regeneration, and recirculation was used after impure upper strata extraction agent was sent to back extraction.Electric screen cabinet 2 is used for to buncher 4 power supplies.
