Abstract

The utility model relates to an engine oil filter element which has low oil resistance, can prevent blocking, and can completely filter hard metal impurities in the engine oil. The whole body of the filter element a barrel-shaped permanent magnet, the surface of the circumference of the filter element is distributed with over oil through holes, both ends are provided with end covers, the end cover on one side is provided with an oil outlet which is communicated with an oil path, and the inner part of the utility model is provided with a paper dielectric filter core. The magnetic adsorption engine oil filter element can simultaneously implement the magnetic physical adsorption and the mechanical pore filtration, which has the advantages of thorough filtration, simple structure and reliable operation.

Description

A kind of magnetic random oil filter core

The utility model relates to a kind of oil filter, particularly a kind of filter element.

Present oil filter, internal combustion engine oil filter particularly, generally adopt tubbiness paper Jie filter core, its operation principle is to utilize impurity in paper Jie cartridge surface hole machinery filtering machine oil, but adopt the filtering of medium hole often to pile up at dielectric surface and produce shutoff because of impurity, the oil resistance increases even the machine oil cutout, so just form a kind of contradiction, if for improving the filtering effect, just must reduce the dielectric surface pore-size, but the oil resistance increases thereupon, the anti-shut-off capacity of filter core reduces, otherwise increase the medium pore-size, the oil resistance reduces, but the filtering effect descends thereupon, for solving the above-mentioned contradiction that the medium filter core exists, prior art is to add an anti-blocking straight-wavy valve at medium filter core oil-in end, when paper Jie cartridge surface is piled up shutoff because of impurity, oil duct and cleaner cavity internal pressure raise under the lubricating oil pump effect, the straight-wavy valve pressurized is opened, machine oil is walked around dielectric surface and is directly entered engine oil recycle system work, though prevented like this because of the cutout of filter core shutoff machine oil, the accident that machinery is worked and caused under unlubricated situation, but by the machine oil that straight-wavy valve passes through is that handle through any filtering at the end, wherein being mingled with the particularly hard metal particle of a large amount of impurity will cause very serious abrasive wear to machinery, not be to solve oil filter so straight-wavy valve is set up in the prior art employing, contradiction effective way between filtering effect and oil resistance.

The utility model purpose provides a kind of magnetic random oil rectifier filter core, and it can not only prevent the shutoff cutout not increasing thorough filtering machine oil half-hard impurity under the oily resistance situation, and simple in structure, reliable operation.

For achieving the above object, the technical solution adopted in the utility model is:

The filter core global sections is a ring-type, and barrel-shaped permanent magnet was evenly equipped with oil hole on its surface.Both sides are provided with end cap, one side end cap central part is provided with the oil-out that communicates with oil circuit, when machine oil is passed through by permanent magnetism filter core circumferential surface through hole, be mingled with that the hard metal particle of iron-based will be adsorbed by magnetic in the machine oil, according to the strong characteristics of magnetic two ends polarity, in cartridge surface many group permanent magnets are set, or in permanent magnet surfaces a large amount of large scales are set and cross oil hole, extreme to increase high-intensity magnetic field, one can improve and machine oil contact area and magnetic field intensity, improve the attached efficient of magnetic, two can reduce the oil resistance, prevent the generation of filter core shutoff situation.

The utility model since adopt many groups, porous permanent magnet be machine oil filter core can be under the situation that not increase the oil resistance thorough filtering machine oil half-hard particulate, have simple in structure, the characteristics of reliable operation.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is a ring type magnetic random oil filter core schematic diagram.

Fig. 2 is an edge formula magnetic random oil filter core schematic diagram by the emperor himself.

Fig. 3 is a combined-type magnetic absorption machine oil filter core schematic diagram.

In the drawings: 1, permanent magnet 2, cartridge surface are crossed oil hole 3, end cap 4, filter core oil-out

5, retainer 6, paper Jie filter core

Permanent magnet among Fig. 1 (1) is a ring-type, and join with " mouse cage " formula retainer (5) machine circle its inboard, in magnetic filter core both sides

The ring-type cylindrical is joined with the inboard circle mutually of filter core end cap (3), and wherein a side end cap (3) middle part is provided with and the oil circuit circle oil-out (4) of joining mutually.

Permanent magnet among Fig. 2 (1) is strip, bulk, and is adhesively fixed with tubbiness woven wire retainer (5), and its overall structure is with embodiment illustrated in fig. 1 identical.

Permanent magnet among Fig. 3 (1) is a tubbiness, the surface is provided with the through hole (2) of being convenient to machine oil and passing through, both sides are provided with the end cap identical with Fig. 1, one cylindrical and tubbiness permanent magnet inwall circle paper Jie filter core (6) of joining mutually is set in tubbiness permanent magnet inboard, constitute the combined type machine oil filter core, it is effective filtering machine oil half-hard particulate not only, but and the while filtering be mixed in non-hard metal impurities in the machine oil on a small quantity, as aluminium bits particulate, impurity such as rubber.
