Abstract

The utility model discloses a magnetic filter, which comprises a shell, a screw thread cover plate and a filter element, wherein the screw thread cover plates is arranged on the top of the shell, an oil outlet is opened on the center, the filter element comprises filter paper and a central tube, wherein the filter paper wraps around the central tube, the top of the central tube is communicated with the oil outlet, a relief valve is arranged on the bottom, and the relief valve comprises a valve bowl, a valve seat and a valve spring. The magnetic filter is characterized in that magnet is arranged on the relief valve. The magnetic filter of the utility model can filter metal impurities whose minimum aperture is 2um, the filtering effect of the filter is increased, the damage to each component of an engine is reduced, the service life of the engine is prolonged, the filter of the utility model can effectively reduce tail gas discharge, the available power efficiency of the engine is increased, and fuel is saved.

Description

A kind of magnetic filter

Technical field

The utility model relates to a kind of machine oil filtering and cleaning device, relates in particular to a kind of magnetic filter.

Background technique

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 the machine oil that contains the small aperture metal impurities enters filter cleaner,, can continue impurity is brought into the miscellaneous part of motor, cause damage because impurity can not get effective filtration; Too much metal impurities can be collected on the filter core, have influenced the filtering effect of filter core.If the time is long when not changing filter paper or automobile starting, all can make the safety valve pressurized overstep the extreme limit and open, cause the impurity of filter core absorption to spray with machine oil.During each vehicle launch, safety valve all can be opened, and makes the machine oil ejection of a large amount of filtered, influences the life-span of motor.

The model utility content

The purpose of this utility model is at the deficiencies in the prior art, proposes a kind of effectively magnetic filter of filtering metal impurity.

The technical solution of the utility model is as follows: a kind of magnetic filter, comprise shell, thread plate and filter core, and thread plate is located at cover top portion, and its center has oil outlet; Filter core comprises filter paper and center tube, and filter paper packet is rolled in around the center tube, and center tube top and oil outlet communicate, and the bottom is provided with safety valve, and safety valve comprises valve bowl, valve seat and valve spring; The place is provided with magnet at safety valve.

Preferred as such scheme, described magnet is arranged on the bottom of safety valve valve seat.

Another kind as such scheme is preferred, and described magnet is arranged on the inwall of safety valve valve seat, is ring-type or watt shape.

Between center tube top and thread plate, be provided with upper end cap and safety check, in upper end cap and projection that safety check contacts, be provided with magnet.

The beneficial effects of the utility model are: the place is provided with magnet at safety valve, can effectively prevent safety valve owing to start or the machine oil that stops up a large amount of filtered when opening pours in filter core.Inwall at oil outlet adds magnet, can adsorb the metallic dust that filter paper does not filter in the machine oil; The utility model can filter the metal impurities that the minimum-value aperture is 2um, has strengthened the filtering effect of filter cleaner; The infringement that each parts of motor are subjected to reduces, and has prolonged engine life; The utility model can also reduce exhaust emissions, increases effective engine power, saves fuel oil, promotes environmental protection.

Below in conjunction with accompanying drawing the utility model is described further.

Embodiment

With reference to Fig. 1, magnetic filter, its filter core comprise center tube 9 and filter paper 10, and filter paper 10 is by hot-setting adhesive and upper end cap 11 and lower end cap 5 bondings; Center tube 9 bottoms are provided with safety valve, and safety valve comprises valve bowl 6, valve spring 8 and valve seat 7, is provided with magnet 4 in the bottom of valve seat 8; Lower end cap 5 belows link to each other with shell 1 by supported spring 2; Upper end cap 11 tops are provided with thread plate 13, are provided with safety check 12 between thread plate 13 and the upper end cap 11; Thread plate 13 and exterior seal ring 15 apical graftings, exterior seal ring 15 is connected with the shell top by sealing ring fixed plate 14; The thread plate center is provided with oil outlet 16, and oil outlet 16 communicates with center tube 9; 12 on upper end cap 11 and safety check are fixed by a projection, are provided with the magnet 3 of ring-type in projection.

When lubricated, machine oil enters from oiler, after machine oil enters filter cleaner, infiltrates through in the center tube by filter paper, then flows out from oil outlet; During by oil outlet, the magnet of oil outlet inwall can adsorb filter paper and filter the remaining metallic dust in back; When safety valve valve bowl was backed down, the machine oil of filtered can at first enter valve seat, and by valve seat the time, the magnet of valve seat bottom can a large amount of metal impurities that absorb in the machine oil behind contact machine oil.Then machine oil just can enter center tube, enters each lubricant housings of motor by center tube again.
