The solid-liquid extraction experimental platform uses a solid-liquid extraction (leaching) method to separate the solid mixture. Solid-liquid extraction is the use of extractants to remove soluble components from solids.

Extraction is a more efficient, selective, and cost-effective method that can replace separation methods such as distillation, evaporation, and membrane technology. Applications of this method include obtaining oil from oilseeds or leaching metal salts from ores.

The test scope includes the following areas:

Familiar with the basic principles of solid-liquid extraction

Effect of extractant flow and temperature on extraction process

Study of single, two and third processes

Effect of extraction material mass flow rate and carousel speed on extraction process

Prove that solid-liquid extraction is a continuous and discontinuous process.

Features:

The operation of the extraction training device is based on the countercurrent principle. This method is used, and the concentration gradient serves as the driving force for mass transfer. That is, the fresh extractant is fed into the rotary extractor to extract the extraction material. The interrupt mode can stop the rotary extractor. Three pumps can be used to transport the extractant from the extractant container, and their speed can be adjusted individually for each stage. During the working process, at least one of the three process pumps is turned on, and the exhaust pump will automatically start, and then the extraction liquid is transferred to the designated container. The rotary extractor rotates slowly above the perforated base, and the material to be extracted is continuously fed into the rotary feeder unit through the screw conveyor. In the unit, the extractant is sprayed, and the extractant valve can be selected for single-stage, two-stage or three-stage Continuous operation to extract materials, the leached extraction residue falls into the designated container after one rotation of the feeder. Each stage is equipped with a conductivity sensor to monitor the separation process. All measured values ??can be displayed using the software. Using a heater with temperature adjustment can adjust and display the temperature of the extractant at the relevant stage.
