Abstract

The utility model relates to a filter device, which particularly relates to an efficient machine oil filter for filtering lubricating machine oil of an engine. The utility model is characterized in that a permanent magnet is additionally arranged on the lower part of a filter core in a shell on the base of the existing machine oil filter, the permanent magnet is used for cleaning and adsorbing iron and alloy iron particles in the machine oil, and micron-class superfine fiber filter cloth is used as the filter layer of the filter core, which can filter out micron-class smaller particles. The filtration efficiency of the particle above the micron-class is raised to more than 90 % from the original 30-50 % by the utility model, the filtration effect of the particle above the micron-class is raised to more than 90 % from the original 30-50 %, the service life of the machine oil can be prolonged, and the service life of the engine can also be prolonged.

Description

The efficient engine oil filter cleaner

The utility model belongs to a kind of filtrating equipment, is specifically related to a kind of filter cleaner that is used to filter engine lubrication machine oil.

At present, the oil filter that various motors adopt, it comprises columniform shell, be located in the shell and the cylindrical filter core and the supported spring thereof of its coaxial arrangement, have oil inlet hole and oil outlet on the cover of shell, filter core is by the inside and outside filter screen of tubular, is clipped in the collapsible filter layer between the inside and outside filter screen, and upper and lower cover is formed.This oil filter does not purify the parts of absorption metallic, can not remove iron and alloyed iron particle in the machine oil, and the filter layer of its filter core is as filter medium with paper, it can only be can play certain filtration than macroparticle more than the micron order to granularity, its filter efficiency is 30～50%, but for granularity is micron-sized less particle, and its filter efficiency only is 3～5%.And the motor that runs up, the metal particle that mutual wearing and tearing produced of its piston ring and cylinder barrel is most of to be micron order, and machine oil also can carry out a large amount of micron-sized motor excrement particles in cyclic process.So existing oil filter can not satisfy actual use needs.

The purpose of this utility model provides and a kind ofly can purify metallic, the oil filter high to the micro-size particles filter efficiency.

For achieving the above object, the technical solution of the utility model is to improve on the basis of existing oil filter, set up one in the enclosure in the filter core bottom and can purify the permanent magnet that adsorbs metallic, the filter layer in the filter core is substituted original filter paper with micron-class superfine fiber filter cloth.Specifically, the utility model is achieved in that a kind of efficient engine oil filter cleaner, it comprises columniform shell, be located in the shell and the cylindrical filter core and the supported spring thereof of its coaxial arrangement, on the cover of shell, have oil inlet hole and oil outlet, filter core is the inside and outside filter screen by tubular, be clipped in the collapsible filter layer between the inside and outside filter screen, and upper and lower cover is formed, wherein, in the enclosure, the bottom of filter core also is provided with permanent magnet, supported spring places between filter core and the permanent magnet, and said filter layer is to be made by micron-class superfine fiber filter cloth.

In the utility model, utilize permanent magnet can purify the metallic that adsorbs in the machine oil, remove iron and alloyed iron particle more than 90% in the machine oil, adopt micron-class superfine fiber filter cloth can filter micron-sized granule, can filter the various useless particle more than 90% in the machine oil, promptly by both purification and filtration, the filter efficiency of micron order and the particle more than the micron order is all reached more than 90%.Can prolong the life time of machine oil like this, increase the working life of motor, reduce the operating temperature of motor.

Now in conjunction with the accompanying drawings and embodiments the utility model is done specific descriptions:

Fig. 1 is an efficient engine oil cleaner structure schematic representation.

As shown in Figure 1, a kind of efficient engine oil filter cleaner, it comprises columniform shell 12, has oil inlet hole 3 and oil outlet 2 on the cover 1 of shell 12.In shell 12, be provided with filter core 13, supported spring 9 and permanent magnet 10 with its coaxial arrangement.Supported spring 9 places between filter core 13 and the permanent magnet 10.Filter core 13 is by the Inner filter net 7 of tubular and outer leaching net 6, is clipped in the collapsible filter layer of being made by micron-class superfine fiber filter cloth 5 between two filter screens, and loam cake 4 and lower cover 8 are formed.Inside and outside filter screen 7 and 6, and upper and lower cover 4 and 8 composition filter frames are used for fixing filter layer 5.The magnetic intensity of permanent magnet 10 is greater than 1000 Gausses.

Circulation machine oil is pumped into by oil inlet hole 3, enter in the shell 12 and the cavity between the filter core 13 of filter cleaner, catharsis by permanent magnet 10, to be adsorbed on permanent magnet 10 greater than micron-sized iron and alloyed iron particle, enter filter layer 5 after filtering by outer leaching net 6 simultaneously, filter micron-sized than granule after Inner filter net 7 is discharged by oil outlet 2, recycle.

In order to improve the adsorptive power of permanent magnet 10, can set up a magnetic force reinforcement plate 11 in the bottom of permanent magnet 10, magnetic force reinforcement plate 11 is made by plain carbon steel.
