Description
Technical field
The utility model relates to macromolecule material preparation areas, in particular to liquid-solid extraction purification devices.
Background technique
Extraction is frequently used in chemical test, its operating process not will cause changing for extracted substance chemical component
Become, so extracting operation is a physical process, extraction is to be used to purify the hand with purifying compound in Organic Chemistry Laboratory
One of section can extract required compound by extraction from solid or liquid.Extraction is often divided into liquid-solid extraction and liquid liquid
Extraction, wherein for liquid-solid extraction, also cry leaching, be to use impurity composition in solvent separating solid mixture, at present for solid
Liquid extracts, and the repeated multiple times washing of batch tank purification process is generallyd use in industry, each to require to be centrifuged after the completion of washing
Powder is returned in kettle again after processing plus water washs again, due to needing to wash repeatedly, be centrifuged, and is all completed in same kettle,
Therefore the efficiency of purifying is very low (wash time is up to 30 hours ~ 40 hours), and water consumption is big, such as sulfone resinoid polymerization reaction
Afterwards, it solidifies in the solution injection water after being reacted, is then again crushed the solidliquid mixture after solidification by crushing process
Contain in these solvents in powdered solidliquid mixture because the powder in solidliquid mixture contains a large amount of solvents at solid matter
The sodium chloride and a small amount of unreacted monomer for having reaction to generate, the very high resin of purity requirement, then need by upper in order to obtain
The liquid-solid extraction for stating batch tank purification process makes the impurity content in toner lower than 100ppm, to meet wanting for application end
It asks.
To solve the above problems, improving the purification efficiency of liquid-solid extraction, reducing water consumption, row those skilled in the art propose can
Liquid-solid extraction is carried out using the equipment of liquid-liquid extraction, that is, uses tower extraction equipment, is tested by natural subsidence, extracted using adverse current
The mode taken carries out the purifying of solid resin, still, for sulfone resinoid mentioned above, since its needs is broken into advance
It is purified again after powdered, and the partial size of sulfone resinoid powder is small, is unevenly distributed, from 20um ~ 3mm etc., bulk density
In the g/ml of 0.2g/ml ~ 0.4, in natural subsidence experiment, the small powder floats of a large amount of partial sizes are extracted on liquid level using adverse current
When taking mode, the contact area very little of the powder and cleaning solution on liquid level is swum in, causes washing effect very poor, purifying rate is very
Low, therefore, this tower liquid-liquid extraction equipment is also not suitable for being applied to the purifying of easily floating toner.
Utility model content
The utility model is intended to provide one kind and can either effectively improve the extraction efficiency of liquid-solid extraction and reduce water consumption, and
The liquid-solid extraction purification devices that the purifying rate of the powdery resin formed by crushing process can again greatly improved.
A kind of liquid-solid extraction purification devices described in the utility model, including extraction tower and multiple holding vessels, each storage
Deposit tank pass through pipeline respectively with extraction tower bottom be connected to and pass through pipeline be connected to respectively with same vacuum pump, each storage
The bottom of tank passes through pipeline and is connected to respectively with same centrifugal pump, and the centrifugal pump also passes through to be connected at the top of pipeline and extraction tower
It is logical；It is from top to bottom arranged at intervals with multiple first annular tracheaes inside the extraction tower, is spaced on each first annular tracheae
Multiple the first opening up stomatas are provided with, all first annular tracheaes are connected to the first air inlet pipe through extraction tower；
Each first annular tracheae lower section and be provided with inside extraction tower the second annular gas pipe, on each second annular gas pipe
Be arranged at intervals with multiple downward opening second stomatas, all second annular gas pipes with the second air inlet pipe for running through extraction tower

The filter plate of conjunction.
A kind of liquid-solid extraction purification devices described in the utility model, by the way that multiple holding vessels are arranged, meanwhile, one is stored up
It deposits tank and is set as slack tank, be put into deionized water in another holding vessel, the different washing of concentration is put into remaining holding vessel
The purifying of hard resin can be completed by above-mentioned purification process in liquid, the cleaning solution for being finished every time and what is finally used go
Ionized water is all stored in previous holding vessel, can be used for the purifying of resin solidliquid mixture to be purified next time；And every time will
The liquid discharge being preset as in the holding vessel of slack tank, then can be ready for being pumped into for liquid next time.Due in holding vessel
Cleaning solution is reusable, the washing of each round, only needs to inject deionized water in a holding vessel thereto, therefore, substantially subtract
The dosage of water is lacked, has reduced production cost, while having been greatly improved again because being not necessarily to the operation being centrifuged again after washing repeatedly
The working efficiency of purifying.Due to being from top to bottom arranged at intervals with multiple first annular tracheaes, each first annular gas in extraction tower
Guan Shangjun is arranged at intervals with multiple the first opening up stomatas, all first annular tracheaes with through extraction tower first into
Tracheae connection is passed through nitrogen into the first air inlet pipe, and subsequent nitrogen inflow is each first annular intratracheal, and by first annular tracheae
