Detailed Description
The present utility model provides a continuous liquid extractor, and the present utility model will be further described in detail below in order to make the objects, technical solutions and effects of the present utility model more clear and definite. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

A steam lifting pipe 1, an extraction tank 2 and a liquid return pipe 3; one end of the extraction tank 2 is an extraction tank inlet 21, and the other end is an extraction tank outlet 22; the extraction cell outlet is provided with an extraction cell outlet valve 221; one end of the steam lifting pipe 1 is provided with a steam lifting pipe inlet 12, and the other end is provided with a steam lifting pipe outlet 11; one end of the liquid return pipe 3 is a liquid return pipe inlet 31, and the other end is a liquid return pipe outlet 32;

The continuous liquid extractor further comprises a disperser;
the disperser is provided with dispersing holes and is arranged in the extraction tank 2;
Further, the disperser may be one of a single-head disperser 4 or a double-head disperser 5.
The continuous liquid extractor provided by the utility model can continuously extract the mixture solution, so that the target extract in the mixture solution can be rapidly extracted, the extraction can be realized by only partially dissolving the target extract by the extractant and being not miscible with the mixture solution containing the target extract and selecting the corresponding disperser according to different density differences of the extractant and the mixture solution, and the whole continuous extraction method is efficient and low in cost.
Wherein, compared with the mixture solution, the high-density extractant or the low-density extractant forms steam through heating, and then enters the extraction tank 2 after reaching the extraction tank inlet 21 through the steam-lifting pipe inlet 12, the steam-lifting pipe 1 and the steam-lifting pipe outlet 11 for condensation, thereby being thoroughly recycled. The height of the extraction tank inlet 21 is higher than that of the steam rising pipe outlet 11, so that the steam of the extracting agent is convenient to further condense and drip, and the height of the steam rising pipe outlet 11 is higher than that of the liquid return pipe inlet 31, so that the extracting agent with the density smaller than that of the mixture solution is convenient to flow back through the liquid return pipe after layering so as to be recycled.

In some embodiments, a single-head disperser 4 is provided in the extraction cell 2. When the density of the extractant is higher than that of the mixture solution, a single-head disperser 4 is selected, the conical tip of the single-head disperser faces to the inlet 21 of the extraction tank, the extractant with high density automatically sinks due to gravity, and the target extract in the mixture solution is extracted while the extractant is sinking, and the set dispersing holes can disperse the extractant, so that the extractant is uniformly dispersed in the mixture solution of the target extract, and the extraction efficiency is improved. If the liquid in the extraction tank 2 is expected to be more, the liquid level may be higher than that of the single-head dispenser 4, a gasket or a bracket may be arranged on the bottom of the single-head dispenser 4 to support the single-head dispenser 4, so that most of the single-head dispenser 4 can protrude from the liquid level, and the dispersion holes can better play a role in dispersion.

In some embodiments, a double ended disperser 5 is provided in the extraction cell 2. When the density of the extractant is smaller than that of the mixture solution, the double-head disperser 5 is selected, the larger-caliber end of the upper opening 51 of the double-head disperser faces the inlet 21 of the extraction tank and can be used for collecting the condensed and dripped extractant, the larger-caliber end of the lower opening 52 of the double-head disperser faces the outlet 22 of the extraction tank, the extractant with relatively smaller density reaches the bottom of the double-head disperser 5 through the upper opening 51 of the double-head disperser and is dispersed through the lower opening 52 of the double-head disperser, the dispersed extractant floats to the upper surface of the mixture solution from the bottom, and the target extract in the mixture solution is extracted while floating. The dispersing holes in the lower opening 52 of the double-headed disperser can disperse the extractant, so that the extractant is uniformly dispersed in the mixture solution of the target extract, and the extraction efficiency is improved.
Further, when the aperture is 1-10mm where the double-ended dispenser upper port 51 communicates with the double-ended dispenser lower port 52, the double-ended dispenser 5 of this aperture range can be adapted for liquid extraction in a laboratory; when the aperture of the communicating position of the double-ended dispenser upper port 51 and the double-ended dispenser lower port 52 is 10-100mm, the double-ended dispenser 5 of the aperture range can be applied to industrial production.
Preferably, when the density of the extractant is less than the density of the mixture solution and the difference between the density of the extractant and the density of the mixture solution is not more than 2%, the extractant within the difference can reach the bottom of the double-ended disperser 5 by inertia and then be dispersed through the lower ports 52 of the double-ended disperser.
Further, when the density of the extractant is smaller than the density of the mixture solution and the density of the extractant is larger than the density of the mixture solution, or when the viscosity of the mixture solution is larger, the mixture solution can be added to the height of all the dispersing holes on the lower opening 52 of the double-headed disperser in the initial stage of the extraction tank 2, the height of the communicating position between the upper opening 51 of the double-headed disperser and the lower opening 52 of the double-headed disperser is increased (for example, by connecting pipes with the same aperture at the communicating position), the condensed and dropped extractant is collected to the increased communicating position through the upper opening 51 of the double-headed disperser after the extraction is started and gradually accumulated, so that the internal pressure of the lower opening 52 of the double-headed disperser is higher than the external pressure, the extractant is pressed out through the hydraulic action and dispersed through the dispersing holes, and the further extraction of the mixture solution is realized.
Further, the single-head disperser 4 may be one of a conical screen plate, a conical sand core plate, a conical polytetrafluoroethylene, a conical stainless steel or a conical cast iron provided with dispersing holes.
Further, the double-ended disperser lower port 52 may be one of a conical screen plate, a conical sand core plate, a conical polytetrafluoroethylene, a conical stainless steel, or a conical cast iron provided with dispersing holes.
Further, the extraction tank 2 is arranged vertically; the extraction tank 2 is made of transparent material, and the transparent material can be one of transparent glass or transparent plastic; wherein the transparent plastic can be acrylic. The liquid level in the extraction pond needs to be used for the operator to observe and judge in order to make timely adjustment, and the extraction pond 2 of vertical setting and selecting transparent material is more convenient to observe the operation, and the extractant liquid drop of condensation can drop on setting up the single-end disperser 4 or the double-end disperser 5 in the extraction pond 2 and disperse when using to promote extraction efficiency.
Further, the extraction tank inlet 21 and the extraction tank outlet 22 are one of a frosted hole, a clamp, a wire hole, a flange plate or a quick connector. Preferably, the inlet 21 and outlet 22 are frosted holes, so as to ensure air tightness during extraction.
Further, the material of the vapor riser tube 1 and the liquid return tube 3 can be one of stainless steel, cast iron, polytetrafluoroethylene, polypropylene, acrylic, ceramic or glass.
When the continuous liquid extractor provided by the utility model is used for replacing the extracting agent and mixture solution system, the disperser in the extraction tank 2 can be directly taken out by tweezers, so that the continuous liquid extractor is convenient to clean. The density of the extractant is higher than that of the mixture solution and the density of the extractant is lower than that of the mixture solution, so that continuous distillation, continuous liquid separation and recycling of the extractant can be realized.
