Description

A kind of extraction tank

Technical field

This utility model relates to rare earth and purifies field, particularly relates to a kind of extraction tank.

Background technology

Rare earth is usually the material separated with oxidation state, generally lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium is called light rare earth or cerium group rare-earth; Gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, lutecium yttrium are called heavy rare earth or yttrium group rare-earth. Rare earth has the new function material of the multifrequency natures such as electricity, magnetic, light and biology simultaneously, it it is the important foundation material of the high-tech sectors such as information technology, biotechnology, energy technology and national defense construction, simultaneously also to transforming some conventional industries, play an important role such as agricultural, chemical industry, building materials etc.

Rare-earth smelting method has two kinds, i.e. hydrometallurgy and pyrometallurgy. Hydrometallurgy belongs to chemical industry metallurgical mode, whole process is among solution, solvent mostly, as the decomposition of rare earth ore concentrate, rare earth oxide, rare earth compound, the separation of single rare earth metal and extraction process adopt the Chemical Decomposition technical processs such as precipitation, crystallization, oxidoreduction, solvent extraction, ion exchange exactly. Now applying more generally organic solvent extractionprocess, it is the common processes of industrial separation high-purity single rare earth element. Hydrometallurgical flowsheets is complicated, and product purity is high.

Hydrometallurgical extraction purifies, need to use extraction tank in the process of rare-earth separating, people, usually in the latent room process of the equipment of manufacture, are fabricated to overall room of diving latent room, and the space thus cause purification, separating is little, the purification & isolation time is short, it is impossible to the state of observation liquid.

Summary of the invention

For above-mentioned situation, for overcoming the defect of prior art, the purpose of this utility model is just to provide a kind of extraction tank, it is therefore intended that the space solving to purify, separate is little, and the purification & isolation time is short, it is impossible to the problem of the state of observation liquid.

Its technical scheme is, including extraction tank body, described extraction tank body is provided with multiple unit box being serially connected, described unit box one end is mixing chamber, the bottom of mixing chamber is provided with latent room, the other end of unit box is clarifying chamber, the end relative with mixing chamber, described clarifying chamber is provided with light phase weir and heavy phase weir, described unit box is arranged side by side and by light, heavy phase weir, latent room forms the structure of serial communication, described mixing chamber is according to light, the flow direction of heavy phase is divided into backflow mixing chamber and unidirectional mixing chamber, the latent room of the bottom of unidirectional mixing chamber is less than the area bottom this unidirectional mixing chamber.

The side of described each mixing chamber is provided with form, and described form closed set has one transparent to look plate.

Bottom described unidirectional mixing chamber, middle part is provided with a dividing plate, described dividing plate upper end is covered with a cover plate, one sidewall of described dividing plate, cover plate and mixing chamber encloses and is set as half body structure, relative with the mixing center of mixing chamber above described cover plate it is provided with through hole, enclosing around this through hole and be provided with coaming plate, the mixing chamber sidewall of described composition half body structure offers and the intercommunicating pore connected bottom light phase weir or heavy phase weir.

This utility model purification by liquid extraction, separating tank manufacture process in, room of diving bottom mixing chamber is fabricated to semi-monolithic and dives room, thus increase the inner space of mixing chamber, increase purify, disengaging time, add transparent sight glasses, can know and observe liquid condition.

Detailed description of the invention

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.

Embodiment one: as shown in Figure 1 to Figure 3, a kind of extraction tank, including extraction tank body 1, described extraction tank body 1 is provided with multiple unit box 2 being serially connected, described unit box 2 one end is mixing chamber 3, the bottom of mixing chamber 3 is provided with latent room 4, the other end of unit box 2 is clarifying chamber 5, the end relative with mixing chamber 3, described clarifying chamber 5 is provided with light phase weir 6 and heavy phase weir 7, described unit box 2 is arranged side by side and by light, heavy phase weir 6, 7, latent room 4 forms the structure of serial communication, described mixing chamber 3 is according to gently, the flow direction of heavy phase is divided into backflow mixing chamber and unidirectional mixing chamber, the latent room 4 of the bottom of unidirectional mixing chamber is less than the area bottom this unidirectional mixing chamber, the side of described each mixing chamber 3 is provided with form 8, and described form 8 closed set has one transparent to look plate 9, bottom described unidirectional mixing chamber, middle part is provided with a dividing plate 10, described dividing plate 10 upper end is covered with a cover plate 11, one sidewall of described dividing plate 10, cover plate 11 and mixing chamber 3 encloses and is set as half body structure, relative with the mixing center of mixing chamber 3 above described cover plate 11 it is provided with through hole 12, enclosing around this through hole 12 and be provided with coaming plate 13, mixing chamber 3 sidewall of described composition half body structure offers and the intercommunicating pore connected bottom light phase weir 6 or heavy phase weir 7.

This utility model is when specifically used, and the stirring area in unidirectional mixing chamber is increased so that it is the stirring efficiency of unidirectional mixing chamber obtains increase, and then improves the speed of purification & isolation.
