Abstract
The invention discloses a high-precision magnetic cleaner, which contains a housing, a supporting spring, an upper end cover, a lower end cap, a safety valve, an inverted valve, a threaded cover plate and a filter core. The filter core is arranged between the upper end cover and the lower end cap and comprises a center tube and filter paper. The safety valve is disposed at the bottom of the filter paper and contains a valve bowl, a valve spring and a valve seat. The bottom of the lower end cap is connected with the housing through the supporting spring. The threaded cover plate is mounted over the upper end cover. The inverted valve is arranged between the treaded cover plate and the upper end cover. The invention is characterized in that high-intensity magnetic sheets are adsorbed on the upper surface of the upper end cover and the lower surface of the lower end cap. The invention has the following beneficial effects: filtration efficiency of the cleaner is raised and service life of an engine is prolonged.
Description
Technical field
The present invention relates to a kind of machine oil filtering and cleaning device, relate in particular to a kind of high accuracy magnetic filter.
Background technology
Present known oil filter, not ideal always in effect aspect the filtration of the metal impurities in the machine oil, can only pore size filter be the impurity of 40～80um.After containing the machine oil entering cleaner of small-bore metal impurities,, can continue impurity is brought into the miscellaneous part of engine, cause damage because impurity can not get effective filtration; Too much metal impurities can be collected on the filter core, have influenced the filter effect of filter core.The maximum pressure that safety valve can bear is 1 kilogram, if the time is long when not changing filter paper or automobile starting, all can makes the safety valve pressurized overstep the extreme limit and opens, and causes the impurity of filter core absorption to spray with machine oil.
Summary of the invention
The objective of the invention is to deficiency, propose a kind of high accuracy magnetic filter of effectively filtering metal impurity to prior art.
Technical scheme of the present invention is following: a kind of high accuracy magnetic filter comprises shell, support spring, upper end cover, bottom end cover, safety valve, check-valves, thread plate and filter core; Filter core is located between upper end cover and the bottom end cover, comprises central tube and filter paper; The filter paper bottom is provided with safety valve, and safety valve comprises valve bowl, valve spring and valve seat; The bottom end cover bottom is connected with shell through support spring, and the upper end cover top is provided with thread plate, is provided with check-valves between thread plate and the upper end cover, is adsorbed with strong magnetic piece at upper end cover upper surface and bottom end cover lower surface.
As the improvement to technique scheme, said strong magnetic piece is a ring-type, and thickness is greater than 1.5mm.
As the improvement to technique scheme, the outer casing inner wall stage casing is adsorbed with magnetic, and said magnetic is a cylinder, is symmetricly set on the outer casing inner wall; Also can be symmetricly set on the outer casing inner wall for a watt shape.
Beneficial effect of the present invention is: after adding strong magnetic piece on upper end cover and the bottom end cover, and can be in the inner magnetic current loop that forms of cleaner; When the machine oil of containing metal impurity got into cleaner, metal impurities can be adsorbed by strong magnetic piece, no longer flows into oil piping system, and the present invention can filter the metal impurities that the minimum-value aperture is 2um; Also can reduce attached to the metal impurities in the filter core, strengthen the filter effect of cleaner; The infringement that each parts of engine receive reduces, and has prolonged engine life.
Below in conjunction with accompanying drawing the present invention is further specified.

The specific embodiment
With reference to Fig. 1, high accuracy magnetic filter, its filter core comprise central tube 9 and filter paper 10, and filter paper 10 is through hot-setting adhesive 4 and upper end cover 11 and bottom end cover 5 bondings; Central tube 9 bottoms are provided with safety valve, and safety valve comprises valve bowl 6, valve spring 7 and valve seat 8; All be attached with annular strong magnetic piece 3 on upper end cover 11 and the bottom end cover 5; Bottom end cover 5 belows link to each other with shell 1 through support spring 2, and shell 1 inwall stage casing is provided with magnetic 16; Upper end cover 11 tops are provided with thread plate 13, are provided with check-valves 12 between thread plate 13 and the upper end cover 11; Thread plate 13 and exterior seal ring 15 apical graftings, exterior seal ring 15 is connected with the shell top through sealing ring fixed plate 14; Thread plate 13 is provided with oiler 17, and is identical with check-valves 12; The thread plate center is provided with oil-out 18, and oil-out 18 communicates with central tube 9.
When lubricated, machine oil gets into from oiler, and a part of metal impurities are adsorbed by the strong magnetic piece of upper end cover; Machine oil infiltrates through in the central tube through filter paper after getting into cleaner, then flows out from oil-out; During through filter paper, the magnetic of filter paper and outer casing inner wall produces dual filter effect to the impurity in the machine oil; When safety valve was backed down, machine oil directly got into central tube from safety valve, and at this moment, the strong magnetic piece of bottom end cover can adsorb the most of metal impurities in the machine oil.
