    • 专利摘要:
    A continuously operating counterflow centrifugal extractor suitable for liquid-liquid extractions wherein solids can be separated with the heavier phase. The extractor (FIG. 1) includes a horizontally disposed drum 8, 9 rotated by pulley 15 which is mounted on hollow shaft extension 6. A transport screw 10 is mounted on a shaft 11 and is rotated by forces developed in the liquid at a rate different than the rate of rotation of the drum. The two liquids are introduced into opposite ends of a mixing zone A. After mixing the heavier phase passes through clarification zone C to outlet 20 and the lighter phase passes through the clarification zone B and on to pump 21 which is mounted on shaft 11 and rotates with the transport screw 10. The difference in rotation rates can be controlled by operation of a throttle 27.

    (54) CENTRIFUGAL EXTRACTOR FOR EXTRACTION BY SOLVENT OF LIQUID CONTAINING A SOLID
    one
    The invention relates to equipment for extraction and can be used in the chemical, food and other industries.
    The closest solution to the invention is a centrifugal extractor for solvent extraction of a liquid containing a solid substance, including a drum rotating around the horizontal axis with zones for mixing and clarifying the extract and removing the extracted liquid with solid particles from the zone of mixing the initial particles channels for supplying opposite sides of the solvent and the extracted liquid to the mixing zone 1.
    A disadvantage of the known extractor is the rapid contamination of the drum with solid particles, as a result of which the extractor must be stopped and cleaned of sediment.
    A plant comprising several extractors is used in which the source fluid moves in countercurrent. However, the solid particles contained in the liquid under the action of the center substance.
    the firing force is crushed and often an emulsion is formed in the extractor, which is poorly separated, not subjected to extraction. Along with the cost of additional filtering, there is still a significant loss of the extracted substance in the non-extracted liquid containing solid particles.
    The purpose of the invention is to more intensively mix a liquid containing a solid with a solvent and continuously discharge the separated solid.
    To do this, in the proposed extractor, the drum consists of conical shells, rigidly connected by large bases, inside the drum is installed coaxially with the possibility of its rotation with a number of revolutions different from the number of revolutions of the drum, while the clarification zones are located in narrowing sections of the shells, and in the zone mixing. between the turns of the screw on the drum of the latter reinforced the plates, having the form of segments, or ribs for mixing the extractable liquid with the solvent. In the mixing zone the turns of the screw must have holes. It is advisable to install a pump for the extraction output on the trunnion of the baja6aija, and a throttling valve on the extracting pipeline. FIG. 1 shows a schematic representation of the proposed extractor, a partial nodal section; in fig. 2 - the same, partial transverse section; in fig. 3 - the right half of the centrifugal extractor with a zone of drying for solid particles, a partial longitudinal section. The centrifugal extractor d.p. of solvent extraction of a liquid containing a solid substance consists of a cone-shaped shells 1 and 2, a drum 5 mounted in a housing on ballpoint fittings 3 and 4 rotating around 1 ×) axially axis axis large bases of conical shells 6 and 7 with pegs 8 and 9, and a screw 10 coaxially mounted inside the drum, mounted on the shaft 1 I with the possibility of its rotation with a number of revolutions different from the number of turns of the drum. The screw shaft 1 1 is mounted in a plaic bearing 12, located in the sub-case 13, fixed in the chain box and in the slide bearing 14 inside the trunnion 8. The drum is rotated by an electric motor (not shown) by means of,; mennaya njKHBa 15, mounted on a pin 8 of the drum. The drum contains zone A after blending of the extracted liquid with the solvent and zones B and C of the clarification of the extract and the initial extractable liquid removed from the s. Mixing zone with solid particles. The clarification zones B and C are located in the narrowing sections of the shells 6 and 7. Shaft 11 lijHeKa and the drum of the latter have channels 16 and 17 for supplying the extracted liquid with solid particles to the mixing zone A from one end and channels 18 and 19 d ; 1 supply in the same zone dissolve; 1 from the other end. The coils 20 of the screw in the shift zone (the holes have holes 21. At the end of the clarification zone C, the drum shell 7 has openings 22 d, t out of separating solid particles. At the end of the clarification zone B, the pump 23 is installed on the trunnion 8 of the drum to extract the extract and On the extract pipe 24, a throttling valve 25 is installed to supply the extract to the line 26. The pump 23 is placed inside the chamber 27 e by a branch pipe 28 connected to the 24 V pipeline, zone A displaced between the turns of the screw on the drum of the latter, reinforced segmetta , the rib 30 for immobilizing the extracted liquid e with a solvent Fig. 3 shows a variant of the extractor, the drum of which also provides for the sludge drying zone D, formed by an additional cone-shaped shell, with the outflow fluid being removed through nozzle 31, the annular channel 32 and nozzle 33. The extractor works as follows. During rotation of the drum 5, the initial extracted liquid with solids, as described by channel 16 and 17, goes to the first turn 34 of the screw 10 in displacement zone A and moves it to Place the burner on the side 7 and the discharge ports 22. Screw 10 rotate with a rotation speed different from that of the drum. Solid particles are thrown onto the drum stepper and transported to the discharge ports 22. The solvent is fed into the extractor drum through channels 18 and 19 to the displacement zone A and after turning the beer with turns of the screw, plates 29 or ribs 30 with the extracted liquid solvent with the extracted material (extract) is transported to the clarification zone B and then enters the chamber 27 and is pumped by the pump 23 through the branch pipe 28 into the pipe 24. The throttling valve 25 creates liquid backwater in the chamber 27 and the pump 23 rotates in kT. As a result of the presence of fluid friction between the rotating pump and the housing 13 of the ball bearing 12, the shields 10 are braked. By varying the depth of immersion of the pump 23 in the extract, the difference in speed can be adjusted during operation. The presence of holes 21 contributes to a better contact with solvent extracted by the liquid network. In zone B, the extract is clarified from entrained particles. Extractable liquid flowing from zone A enters zone C of clarification, moreover, if solvent is contained in the extractable fluid, then through channel 35 it is directed to the clarifying zone B. Solid particles with a part of extraction of my liquid are removed through windows 22 into the chamber 36 and out of it through the nozzle 37. In the presence of the zone D of the grate in the drum 5, solid particles enter the latter and are dried. The liquid is removed through the nozzles 31 into the chamber, and out of it is discharged through the nozzle 33. The precipitate is removed from the drying zone D through the windows 22. The proposed extractor, when used to extract the culture broth to produce an antibiotic, such as penicillin, eliminates the broth pre-filtration and increases the output of the antibiotic is about 10-15%. The design of the extractor provides intensive displacement of the source liquid with the solvent and continuous unloading of the separated solid particles.
