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.

The utility model adds a coarse filtration filter core in magnetic-grid-type fluid filter, the filter element filtering after filtering as magnetic-grid-type with the filtering residual dirt, guarantees to filter fully reliable.The utility model is used for common hydraulic pressure, but the lubricating system one-level is accomplished and filtered, and simplifies filter plant; Be used for High Definition Systems and only need after the utility model, to set up the smart filter of one-level filter core.

Summary of the invention:

The technical problem that the utility model will solve is a kind of knockdown hydraulic pressure, lubricating oil filter plant to be provided, simplification filtration system, the filter efficiency that improves.

The combined type oil filter of the utility model is formed by magnetic-grid-type filter and polymer composite cartridge combination.Like Fig. 1, shown in Figure 3, bar magnet (2) annular array, evenly distribute, be placed in and form magnetic grid in the filter cylinder (4); On the installation site of a bar magnet, substitute bar magnet therein with a polymer composite element kit (6).Have I mouth, O mouth on the filter cylinder, be the import and export of combined type oil filter.Fluid at first fully contacts with bar magnet after getting into filter cylinder from the I mouth, the ferromagnetic particle in the bar magnet absorption fluid, and wrap up in the nonmetal and non-ferromagnetic debris of band portion.

As shown in Figure 2, have C mouth and D mouth on the filter core cylinder of element kit (6-2), be respectively the import and export of element kit.C mouth and filter cylinder inner chamber together with, the D mouth links to each other with the O mouth of filter core inner chamber and filter cylinder.

Under the oil pump dynamic action, the fluid in the filter cylinder gets into filter core cylinder from the C mouth of filter core cylinder, passes filter core from the outside of filter core (6-1) and gets into filter core inner chamber, residual contamination thing in the filtering fluid.Cleaning fluid flows out from the O mouth through the D mouth.

There is a hydraulic cylinder (3) at filter cylinder middle part, is used for jack-up or closes the loam cake (5) of magnetic-grid-type filter.A, B are the advancing of hydraulic cylinder, oil return opening.After bar magnet or filter core had adsorbed the dirt of q.s, hydraulic cylinder B mouth advanced hydraulic oil, the place's oil return of A mouth, and jack-up oil filter loam cake is taken bar magnet and element kit out of, removes dirt or renew cartridge more on the bar magnet.Afterwards, hydraulic cylinder advances, oil return is switched, and the loam cake of magnetic-grid-type oil filter resets and covers tight.The effect of two guide rods (1) is that hydraulic cylinder play the guiding role when flexible.

The bar magnet main body is the combination of strong magnetic material neodymium iron boron polylith multipolarity, high adsorption capacity; The bar magnet cover is with stainless steel casing, in order to cleaning.Adopt the metallic particles in the bar magnet absorption fluid, filter efficiency is high, reuses, and saves filter core; Adopt polymer composite slightly to consider the filter element filtering residual dirt, filtration is reliable, pollutant holding capability is big, the life-span is long, it is little to pass through resistance.Therefore the combined type oil filter can be handled the above high-viscosity oil of viscosity 100cst, and filter efficiency is high, and equipment operating cost is low.

The characteristics of the utility model are that magnetic-grid-type fluid filter and coarse filter element are integrated in the cartridge filter, have simplified the fluid filter.Can be used for the filter eventually of general hydraulic pressure, lubricating system, also can be used as the coarse filtration of high-precision hydraulic, lubricating system.

The utility model is that a kind of fluid focuses on equipment, can reuse for a long time, can effectively reduce cost of equipment maintenance.The utility model both can be used for the fluid on-line filtration, also can be used for contaminated fluid and regularly focused on.
