Abstract
The utility model provides a magnetic grid oil filter which is a novel oil purification equipment. According to the utility model, a magnetic grid is formed by neodymium-iron-boracium ferromagnetic rods to adsorb metal particles in the oil along with partial nonmetal particles so that high filtering efficiency is obtained and the equipment operation cost of replacing filter cores can be reduced. However, by using the magnetic grid oil filter, the complete removal of the nonmetal and non-ferromagnetic metal dirt in the oil cannot be ensured. According to the utility model, a coarse filter core is additionally arranged in the magnetic grid oil filter to filter the rest dirt. By using the combined oil filter provided by the utility model, a magnetic rod is replaced with a high polymer composite material filter core module at the magnetic rod mounting position in the original magnetic grid oil filter. After the filtered oil enters a filter cylinder from a port I, ferromagnetic particles in the oil are first adsorbed by the magnetic rod; and then the rest pollutants are filtered by the filter core. Sufficient dirt removal is ensured and the filter equipment is simplified. The magnetic grid oil filter provided by the utility model can be used for final filtering of common hydraulic and lubricating systems and can be also used for coarse filtering of high precision systems.
