Abstract
A three-dimensional multi-layer valve hole contained filter core is mainly made of bar-shaped filter layers in an overlapping way, a folding way or a cylindrical winding way; each filter layer is full of valve holes; the valve holes on contacted filter layers are staggered instead of overlapped; when engine oil enters the filter core and is filtered, the engine oil flows passes through multiple layers of staggered valve holes to generate a derivative flow, and entrained impurities remain in the valve holes and filter layers, so that the blockage rate of the impurities on the surface of the filter core is reduced; meanwhile, the flow of the engine oil is increased and the flow velocity of the engine oil is reduced; namely, the effective filtration area is increased; and the overall filtering efficiency of the filter core is improved.
Description
Technical field
The utility model is a kind of machine oil filter core, particularly relates to a kind of stereoscopic multi-layer valve opening and contains filter core.
Background technology
The machine oil that uses in the various plant equipment, it is lubricated that effect mainly contains one, provides film lubrication to reduce friction and to wear and tear between moving parts; The 2nd, cooling is as thermal medium cooling effect from critical surface is taken away heat; The 3rd, sealing, filling casing wall, the injustice place on valve stem surface and in the oil sealing of turbocharger, sealing; The 4th, cleaning is taken back sump by flowing of machine oil with the carbide on the part, greasy filth, the logical circulation of wear metal particle, and is unlikely at piece surface formation incrustation; The 5th, damping and cushioning effect, particularly high pressure parts are such as gear and push rod etc.; The 6th, anti-oxidation and corrosiveness shield to part.Machine oil through after a while work, has been brought into play contaminated after the above-mentioned function and the mistake effect need to be changed in machine.In order to prolong the service life of machine oil, the most frequently used method is to use oil strainer, returns machine relaying supervention behind the contaminant filter that oil circulation is taken back and waves due function.The oil strainer that uses at present all mainly to be filtered into Main Means, filters the impurity in the machine oil, reduces the possibility that parts are worn.The filter core of existing oil filter all is to filter with papery, also have and adopt multilayer staple fibre or log paper etc. to roll in order to improve filtering accuracy to form, although filtering accuracy increases, but still the actual too small problem of filter area of existence, because the impurity that is filtered out when outermost surface is abound with obstruction, even inner material does not lose function, but whole filter core has just lost filtering function, greatly shorten the service life of filter core, also affected the service life of machine oil and machinery simultaneously.
The utility model content
For above-mentioned the deficiencies in the prior art, the utility model provides a kind of stereoscopic multi-layer valve opening to contain filter core, and is little to solve the prior art filter area, and filter core is short service life, the problem that filter pressure is high.
The technical solution of the utility model is as described below: it is mainly made with stacked, collapsible or cylinder takeup type by the filtering layer of strip and block, be abound with the valve opening of through hole shape on the filtering layer of every one deck, the valve opening on every layer of filtering layer that is in contact with one another be dislocation rather than overlap.When machine oil entered filter element filtering, machine oil can produce the stream that spreads out by percolation in the valve opening of much dislocation of layer, its impurity of carrying secretly is remained in each layer valve opening and the filtering layer, falls the most surperficial impurity plugging rate of end filter core; Simultaneously not only also strengthen the flow of machine oil but also reduced the flow velocity of machine oil, namely promoted the effective area that filters; Improve on the whole the filter efficiency of filter core.
The beneficial effect that the utility model compared with prior art has is to have strengthened the effective area that filters, impurity retained be included in the filter core, thus filter efficiency and the Acceptable life of raising filter core.
Description of drawings
Fig. 1 is strip and block filtering layer schematic diagram of the present utility model, comprising strip and block filtering layer 1, valve opening 2.
Fig. 2 is stacked structural representation of the present utility model, comprising strip and block filtering layer 1, valve opening 2, multi-layered filtering element body 3, leach and retain impurity 4, leach and retain impurity 5.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As depicted in figs. 1 and 2, the enforcement of stacked structure of the present utility model is mainly constituted with overlapped way by the strip and block filtering layer 1 more than three, be abound with valve opening 2 on the strip and block filtering layer 1, valve opening 2 is that the form with through hole exists, valve opening 2 on per two contacted strip and block filtering layers 1 must stagger and repeated hole not, and whole like this filter core inside also just is equivalent to one with the stereochemical structure of a plurality of cavity volumes; When with the machine oil of the impurity side inflow from filter core, the better fluid of other plan-position circulations of the relative filtering layer in valve opening 2 places on every one deck strip and block filtering layer 1 will inevitably first-selection be flowed through it, the valve opening 2 of every one deck all misplaces, so machine oil is not to filter with straight route in filter core inside, and ceaselessly filter in the stream mode of spreading out, like this, in the machine oil with have impurity then in filtration, to be remained between each layer strip and block filtering layer 1 and valve opening 2 in.Such benefit one is to have improved the retention amount of filter core to impurity, the 2nd, the existence of valve opening 2 has strengthened the flow of machine oil and the stream mode of spreading out reduces the flow velocity of machine oil, because of flow/flow velocity=filter area, also just promoted the effective area that filters, therefore improve on the whole the filter efficiency of filter core.
The described stereoscopic multi-layer valve opening of the utility model embodiment contains filter core, implements except the stacked structure that can resemble as shown in Figure 2, also can be made into accordion structure and cylinder takeup type structure is implemented.
The material of the described strip and block filtering layer 1 of the utility model embodiment can be filter paper, nonwoven, filter membrane, if when implementing with stacked structure, the material of strip and block filtering layer 1 can also be metal sintering felt, polyethylene sintering, metal powder sintered.
The valve opening 2 that is abound with on the described strip and block filtering layer 1 of the utility model embodiment can be round, or rule or irregular polygon; The aperture of valve opening 2 must be less than the hole back gauge of any two valve openings 2.
Technical solutions of the utility model are filtered except can be applicable to machine oil, can also be applied in the filtration art of other fluid liquid.
