A kind of rare earth leaching liquid removal filtration pipe

[technical field]

The utility model relates to Rare Earth Production apparatus field more particularly to a kind of rare earth leaching liquid removal filtration pipes.

[background technique]

China is the country that rare earth reserves are most in the world, and Elemental partition is comprehensive.By nearly development in 40 years, the whole nation is Most huge rare-earth industry in the world is established, becomes the world's largest Rare Earth Production state, maximum rare earth country of consumption and maximum Rare earth supply country.During Rare Earth Production, it is directly added into reaction kettle after being filtered after rare earth dissolution by filtering and impurity removing device Reaction, existing leaching liquid exclusion device, device is simple, and structure is single, and common leaching liquid exclusion device is single mistake Filter, can not classified filtering, clean not thorough enough, rest in leaching liquid there are also tiny impurity, to subsequent to leaching liquid Extraction of rare eart exerts a certain influence.

If necessary to increase two-stage filter, occupied area is excessive, and input cost is high.

The utility model is to research and propose in view of the deficiencies of the prior art.

[utility model content]

The shortcomings that the purpose of the utility model is to overcome the above-mentioned prior arts provides a kind of can remove in rare earth leaching liquid The rare earth leaching liquid removal filtration pipe of fine impurities.

The utility model can be achieved through the following technical solutions:

The utility model discloses a kind of rare earth leaching liquid removal filtration pipe, including screen pipe and delivery line, the filterings Upper flange is equipped with above pipe, the screen pipe is equipped with integrally formed impurity-discharging pipe, and the impurity-discharging pipe upper end is deep into screen pipe Inside, filter device is additionally provided with inside the screen pipe, and the filter device includes that bottom is placed on the back taper above impurity-discharging pipe Shape filter plate is placed with silica wool filter layer on the filter plate inner wall, is placed with filter screen inside the silica wool filter layer, It is respectively and fixedly provided with above the filter plate, silica wool filter layer and filter screen and extends to outer peripheral side and be fixed to each other with aforementioned upper flange Flanging.It is connected above screen pipe with dissolving tank, the lysate in dissolving tank is removed greatly by the filter screen that dissolving tank carries Granule foreign, when the lysate with fine impurities passes through the filter device in screen pipe, fine impurities are by screen pipe After filter screen, partial impurities are retained on filter screen, and for lysate after silica wool filter layer, fine impurities are retained in quartz Cotton filters layer surface, gathers impurities removal bottom of the tube later, is discharged by impurity-discharging pipe, passes through flange arrangement and dissolving tank drainpipe phase Connection, leakproofness is good, and the filter device in screen pipe is easy to remove and clean.

Preferably, the upper flange is equipped with the bolt hole that bolt passes through.

Preferably, the export pipe end is equipped with lower flange, and the lower flange is equipped with the bolt hole that bolt passes through.

Preferably, the filter plate bottom end is fixedly connected with position-limiting tube compatible with impurities removal bore.Filter plate passes through Position-limiting tube is fixed at the top of impurity-discharging pipe, is avoided filter device and is separated with impurity-discharging pipe, avoids impurity and be discharged into instead by delivery line It answers in kettle, influences reaction efficiency.

Preferably, valve is additionally provided on the impurity-discharging pipe.

The utility model has the following advantages compared with prior art:

Without increasing large-scale filter plant, only the conduit among existing dissolver and reaction kettle is improved through row, By increasing filter screen and silica wool filter layer, the fine impurities in lysate are all removed, impurity effect rare earth is avoided Element refines.
