Laboratory small scale centrifugal extractor is mainly small-scale liquid-liquid extraction equipment for small-scale tests in laboratories of enterprises or universities. Among them, the CWL50-M centrifugal extractor is a commonly used experimental centrifugal extractor on the market. This equipment is a small-scale extraction equipment independently developed and produced by Zhengzhou Tiei Extraction. It is mainly convenient for customers to conduct small-scale experiments before choosing industrial extraction equipment, and formulate process plans and select equipment according to specific experimental data.
At present, the common materials of the small-scale extraction equipment CWL50-M centrifugal extractor are mainly polymer fluorine materials, 304 stainless steel, 316L stainless steel, organic glass, etc. Polymer fluorine materials can resist strong acid corrosion and are suitable for extraction operations with corrosive liquids. 304 stainless steel and 316L stainless steel are commonly used materials with high strength and corrosion resistance, and can withstand high centrifugal forces, which are suitable for high-intensity centrifugal extraction. Organic glass is transparent and suitable for the operation requirements of observing the extraction process while extracting. Different materials are not good or bad, and they are mainly selected according to the specific liquid conditions and production needs of the customer.
The CWL50-M centrifugal extractor has a compact structure, simple and convenient operation, requires few auxiliary equipment, and occupies a small area. It can directly simulate the multi-stage countercurrent extraction and multi-stage cross-current extraction processes using a small amount of feed liquid. The equipment can handle systems with small density difference between the two phases and high viscosity, and has a strong demulsification ability.
CWL50-M centrifugal extractor technical parameters
| Type | Drum diameter(mm) | Mixed flux(L/h) | Inlet and outlet pipe diameter(mm) | Motor power(kw) | Single unit dimensions(mm) |
| CWL50-M | 50 | ≤50 | DN20 | 0.18 | 400×370×900 |
The operation of laboratory centrifugal extractors mainly includes multi-stage countercurrent extraction equipment, multi-stage cross-current extraction equipment, and single-stage centrifugal extraction equipment. The selection is based on the actual operation needs of the customer. The most commonly used is multi-stage countercurrent extraction, which can be widely used in extraction, stripping, washing and other processes in many fields such as pharmaceuticals, chemical industry, hydrometallurgy, environmental protection, petrochemicals, etc.
