Liquid separation equipment is an important tool in industrial production and experimental research, which can effectively extract and separate substances in liquid. This article will introduce 6 common liquid separation equipment, including centrifugal extraction machine, laboratory extraction tank, membrane separation equipment, filtration extractor, rotary separator and gravity settling equipment.

1. Centrifugal extraction machine
Centrifugal extractor is a kind of equipment that uses centrifugal force for liquid-liquid separation.

Its main working principle is to put the liquid to be separated in the centrifuge tube, and then separate the liquid of different density by centrifugal force.

Centrifugal extraction machine has the advantages of large processing capacity, high separation efficiency and simple operation, and is suitable for the separation of oils, spices, pigments, alkaloids and other substances. At present, the more popular centrifugal extraction machine has# three body separation centrifugal extraction machine# and so on.

2. Laboratory extraction tank
Laboratory extraction tank is a kind of liquid-liquid separation equipment commonly used in chemical laboratories.

Its main structure includes a water bath with a heater and stirrer, and a collector for collecting the separation.

The laboratory extraction tank can be used to separate organic compounds such as phenol, ethyl acetate and ethanol, which has the advantages of simple operation and high efficiency.

3. Membrane separation equipment
Membrane separation equipment is a kind of equipment that uses the selective permeability of the membrane for liquid-liquid separation.

Its main principle is to separate the liquid to be separated through a special membrane, so that the different components in the membrane on both sides of the retention or release of different rates, so as to achieve separation.

Membrane separation equipment has the advantages of large processing capacity, high separation efficiency, simple operation, etc., and is suitable for the separation of oils, spices, pigments, alkaloids and other substances.

4. Filter extractor
A filter extractor is a device that uses the principle of filtration to separate different components in a liquid.

Its working principle is to add the liquid to be separated to the filter, add an appropriate amount of detergent and extraction agent, and make the solid particles settle to the bottom. The solid particles at the bottom were then poured to give both solid particles and solution products.

The filter extractor has the characteristics of large processing capacity, high separation efficiency and simple operation, and is suitable for processing large-scale liquid samples.

5. Rotary separator
The rotary separator is a kind of equipment that uses the principle of centrifugal force to separate the different components in the liquid.

Its working principle is to put the liquid to be separated into the rotating tube, and then add an appropriate amount of detergent and coagulant to make the solid particles settle to the bottom. By continuously rotating the tube, the solid particles are separated from the liquid, thereby obtaining two products, solid particles and liquid.

The rotary separator has the characteristics of large processing capacity, high separation efficiency and simple operation, and is suitable for processing large-scale liquid samples.

6. Gravity settling equipment
Gravity settling equipment is a kind of equipment that uses gravity for liquid-liquid separation.

Its main principle is to place the liquid to be separated in a closed container, and then separate the liquids of different densities by gravity.

The gravity settling equipment has the advantages of large processing capacity, high separation efficiency and simple operation, and is suitable for separating grease, spices, pigments, alkaloids and other substances.

In short, liquid separation equipment plays an important role in actual production and research. In addition to the 6 common liquid-liquid separation equipment described above, there are other common liquid-liquid separation equipment, such as rotary evaporators, distillation columns, etc. In practical application, appropriate equipment should be selected for separation operation according to the actual situation. At the same time, it is also necessary to pay attention to the maintenance and maintenance of the equipment to ensure its normal operation and stability.
