Description
Technical field
The present invention relates to a kind of leaching device and leaching methods, and in particular to a kind of compact-sized, easy to operate, labour is strong
Spend it is low, it can be achieved that automation mechanized operation efficient solid-liquid counter-current extraction device.
Background technology
Liquid-solid extraction also referred to as leaches, and is a kind of unit that solvent-applied extracts the soluble constituent in solid material
Operation.The raw material leached, is in most cases the mixture that solute is formed with insoluble solid, and solute is leaching institute
The soluble component needed, generally undissolved solid is referred to as carrier or inert substance in a solvent.
Solid phase extraction is widely used in hydrometallurgy, food industry, chemical industry and pharmaceutical industry of Chinese medicine, to obtain tool
There is the concentrated solution of application value component or for removing the solable matter being mingled in insoluble solid.Always such as metallic ore
Multi-component, required metal leaching separation will can just be obtained from ore, leached from ore with sulfuric acid or ammonia solution and
It obtains copper, obtain gold with sodium cyanide solution leaching separation.Using natural materials as raw material, various organic matters can be obtained using leaching method
Matter such as extracts sugar with hot water from beet, edible oil is extracted from soybean, peanut, rice bran, corn, cottonseed with organic solvent.From
Various pharmaceutical substances are extracted with water or organic solvent in the root of plant, leaf, skin, are such as extracted from Radix Glycyrrhizae with 75% ethanol water
Glycyrrhizic acid.In addition, extracting the model that active principle therein also belongs to solid-liquid extraction with organic solvent from the mycelium of zymotic fluid
Farmland, such as the production of Co-Q10.
The effect once extracted in solid leaching is extremely limited, is often carried using multistage to improve extraction efficiency
The mode taken carries out.Multistage extraction, which is divided into, extracts for the extraction of cross-flow multistage with countercurrent multistage.The extraction of cross-flow multistage is common at present
A kind of extracting method, but the quantity of solvent that uses of cross-flow multistage extraction is big, and obtained extract concentration is low, and extraction time is long,
Extracting solution concentration amount is big；The quantity of solvent that countercurrent multistage extraction uses is small, and obtained extract concentration is high, and extraction time is short, extraction
Liquid concentration amount is small.
Solid-liquid leaching operation is generally divided into intermittently operated and semicontinuous operation.Intermittently operated is characterized in extracting solution and solid
It is intermittently discharged after completing to extract, solid is immobilising in extraction process, and solvent once extracts after being added；For
For multistage cross flow extraction, after single extraction, after separating extracting solution, solvent is added again and extracts, until extraction
After number meets technological requirement, extracting solution is separated, carry out discharging and is packed into new material.Most of extraction equipment is autoclave or column
Formula equipment.Semicontinuous operation is characterized in that extracting solution in continuous discharge, there may come a time when that the cutout that will appear the of short duration time, solid exist
It is discharged after completing leaching, and solid does not flow in extraction process, until when meeting technological requirement.Most of this equipment
For column type equipment, plural serial stage extracts successively.The number of units of extraction equipment is that extraction time adds 1, such as extraction 5 times, then is arranged 6
Equipment, extractor successively use by grading extraction, additional 1 solid material new as excretion waste solid and installation.
It is in continuously enter that continuous counter-flow extraction equipment, which is characterized in that solvent and solid matter all, extracting solution and waste solid
Also it is in continuous discharge, solid is in counter-current flow with solvent, and mass transfer is carried out in flow process.In recent years, extract in solid-liquid continuous flow upstream
In taking, device is still based on single-screw or double helix.For the object system of more difficult separation, the length needed using single-screw form of device
It spends limited, it is difficult to reach the requirement of separation.Therefore, the leacher that single-screw adds Vltrasonic device has been developed recently, to improve leaching
Rate；Duplex form be actually in single coil configuration, added one for solid --- the spiral of liquid separation forms pair spiral shells
Revolve extractor.The drawbacks of equally there is also single-screw extractors.
