Description
Technical field
Centrifugal extractor technical field is the utility model is related to, specifically a kind of centrifugal extractor feeding structure.
Background technology
Extraction is to be used for purifying one of means with purifying compound in Experiment of Organic Chemistry.By extraction can from solid or
Required compound is extracted in liquid mixture, conventional is liquid-liquid extraction.Above-mentioned extraction principle is：Utilize compound
It is immiscible at two kinds（Or slightly soluble）Solvent in solubility or the difference of distribution coefficient, compound is shifted from a kind of solvent
Into another solvent.By repeated multiple times extraction, the compound of the overwhelming majority is extracted.Centrifugal extractor is to utilize
Powerful centrifugal force caused by rotary drum high-efficiency rotating, it is that two kinds of different and immiscible liquid of density are mixed rapidly, divided rapidly
From new, fast and efficiently liquid-liquid extraction equipment.
Centrifugal extractor in the market uses circular-gap structure mostly, two-phase feed liquid enter centrifugal extractor housing with
Annular space among rotary drum, mixing is realized by the high speed rotation of rotary drum in above-mentioned annular space.Mixed feed liquid is by bottom of the drum
Small charging aperture aspirate into rotary drum.Above-mentioned feeding structure does not feed impeller, real by liquid level difference and the collective effect of centrifugal force
Now feed.The feeding structure is ensures inlet amount, and rotating speed is big compared with high mixing intensity, and power consumption is big, and efficiency is low.
In the market also has installs impeller on rotary drum axle, by the centrifugal extractor feeding structure similar to latent room, but its
The shortcomings of structure design is unreasonable, complicated, fragile, is unfavorable for maintaining, and inlet amount is small.
Utility model content
For the above situation, to overcome the defect of prior art, the utility model provides a kind of centrifugal extractor charging knot
Structure, effectively solves the problems such as existing centrifugal extractor mixing intensity is big, Centrifugical extraction rate is low, complicated, fragile.
The utility model includes motor shaft, rotary drum, it is characterised in that the lower end of the motor shaft extends to the bottom of rotary drum
End, rotary drum are fixed on motor shaft through key and keyway, and the lower end of motor shaft is provided with the charging terminal being placed in below rotary drum, motor
Sealing plate is installed among axle and charging terminal, the lower end for feeding terminal is provided with replaceable impeller.
Preferably, the sealing plate and charging terminal are through being bolted on motor shaft.
Preferably, the charging terminal is cylinder-like structure, and charging terminal is located at below rotary drum, and charging terminal diameter is less than
Roller diameter, feed end subcenter axis and rotary drum central axis overlap.
Preferably, the sealing plate is made up of corrosion resistant composite.
Preferably, described impeller is connected through screw thread with charging terminal, facilitates extraction process demand to realize quick-replaceable.
Preferably, described impeller is axial wheel.
Preferably, described rotary drum, charging terminal, impeller material are one in Stainless steel 316 L, polymer composite
Kind.
The utility model clever structure, using setting the centrifugal extractor feeding structure of replaceable impeller in charging terminal,
Axial wheel mixing intensity is moderate, and charging ability is strong, and low in energy consumption, energy-conserving and environment-protective, centrifugal extractor is simple in construction, easy to process,
It is convenient to change, and can meet various industrialization systems, be greatly enlarged the industrial applications of centrifugal extractor.
