Background technology
Liquid-liquid extraction is a kind of separation means commonly used, extensive use during, zymotic fluid extraction synthetic at medicine, chemical industry, effective ingredients in plant separate.The stirred tank formula extraction mode that at present a lot of companies adopt tradition to fall behind basically, each liquid feeding, mix, standing demix, at the bottom of still, tell two phase liquid again through visor manual observation, accomplish single extraction.And extract and separate needs repeated dispensing could extract fully usually, so need repeatedly repetitive operation could accomplish complicated operation; Labour intensity is high, and the solvent use amount is big, and layering was difficult for seeing clearly when especially two phase colors were close; Be prone to produce the operation deviation; Operate more difficulty when a small amount of solid content or emulsification are arranged, extraction yield is low, also need dispose a large amount of transfer jars simultaneously.
Recently exploitation has the Centrifugical extraction device, though operation is simple, normally used is inflammable and explosive high volatile volatile organic solvent, and high speed centrifugation is prone to produce dangerous, does not exist solvent to apply mechanically problem, and the solvent use amount is big.At present, continuous countercurrent extraction tower development is also very fast, but only is applicable to that tank solution handles, and all is that batch (-type) comes out and be extracted solution in fact more the time, and inapplicable.
The utility model content
To the deficiency that prior art exists, the purpose of the utility model is to provide a kind of tank switching that do not need, and single extraction is accomplished, and reduces the solvent use amount greatly, and the unidirectional continuous liquid-liquid extractor of automation completion.
The purpose of the utility model is to realize like this; It is to connect a separation chamber on the top of extraction cell; The separation chamber is the back taper hollow container, and the bottom, separation chamber is communicated with extraction cell, and top, separation chamber is provided with the extract outlet; The extract outlet is communicated with the extract storage tank, and the bottom, separation chamber is provided with remaining extractant outlet.The top of separation chamber connects a frequency control motor.Extraction cell is the sleeve of a band insulation jacket, and the bottom is provided with leakage fluid dram and extractant import, and top is provided with treats the extraction solution import, and extractant import department is communicated with the extractant storage tank through pipeline, and check valve, flowmeter and pump are housed on the pipeline.The inside of extraction cell is provided with agitating device; This agitating device includes the rotating shaft that vertically is arranged in extraction cell axis place, be fixed in the extraction cell inwall and by constant spacing deciding ring and be fixed in the rotating shaft and be distributed in the rotating rings in the middle of per two adjacent fixed rings at interval, the rotating shaft of agitating device is passed the separation chamber and is connected with the output shaft of frequency control motor.
When equipment is big,, reduce cost of manufacture and difficulty in order to reduce the length of rotating shaft; Also can change the position of separation chamber, at this moment, said separation chamber is a hollow container; This hollow container bottom is a back taper, also can suppress the end socket shape for ellipse, is positioned at extraction cell one upper lateral part; Be communicated with through pipeline with extraction cell, said frequency control motor is fixed in the extraction cell top.
The beneficial effect of the utility model is that adopting the utility model structure to extract does not need tank switching to accomplish, and can once obtain the high concentration extract; Greatly reduce the solvent use amount; Reduce solvent recovery loss and energy consumption, simplified operation greatly simultaneously, increased substantially extraction efficiency.It has changed the periodic running pattern, adopts auto-control mode, has reduced labour intensity.
