Meanwhile, the organosilicon raw material still has certain moisture, and the water needs to be analyzed out when in use, otherwise, the polymerization reaction can not be effectively carried out to produce the silicone oil. The filtering devices commonly used in the prior art have: metal mesh filters, plate and frame filter presses, cloth bag filters, and lean-type filter core precision filters. The metal screen filter can only be used for carrying out primary filtration on organic silicon base raw materials with various viscosities to remove impurities with larger particle sizes; the plate-frame filter press is suitable for filtering impurities with low viscosity and large particle size, and treating a large amount of products, but particles below the micron level are easy to filter; the cloth bag type filter is generally used for filtering low-viscosity organic silicon raw materials or products with the particle diameter of impurities of several micrometers or more, the treatment capacity is small, a filter cloth bag needs to be frequently replaced, and the organic silicon raw materials or products cannot be reused; the lean type filter core precision filter can filter low-viscosity organic silicon raw materials or products and micron or higher-grade particles, has small treatment capacity, is expensive, and cannot be repeatedly used. In recent years, with the increasing market usage of organic silicon, the demand for high-quality, high-transparency and ultralow-water-content organic silicon base materials is increasing, and the requirements for technologies and equipment which are economical and effective, can treat and filter impurities in large quantities and remove trace water are also increasing.
