Description
Technical field
The utility model relates to filter plant field, in particular to a kind of automatic backwash lubricating filtering device.
Background technology
The effect of filter is that the solid sundries such as iron oxide, dust being contained in filter medium is removed, and reduces mechanical wear, guarantees the filter of main process equipment stable operation.
At present, filter can be divided into surface type, degree of depth type and magnetic filter by filtering material both at home and abroad.They to the filtration of solid pollutant by direct obstruction with adsorbed.
1, surface filter, is almost all stopped the side in filter element surface upstream by the particulate pollutant of filtering.On material for core, there is uniform demarcation aperture, can filtering be greater than the solid particle of demarcating aperture.The filter that belongs to this class has edge type, net formula and chip; Such filter feature is simple in structure, and through-current capability is large, easy to clean, but filtering accuracy is low.
2, degree of depth type filter, the filter core of degree of depth type filter is porous transmissibility material, inside has tortuous roundabout passage.The contamination particle that is greater than aperture is directly stopped at the outer surface by fluid upstream, and less particle is while entering filter core inner passage, because the effect that is subject to surface tension (Molecular Adsorption power, electrostatic force etc.) departs from a fluid stream, and be attracted on the inwall of filtration channel.Therefore the existing direct obstruction of the work principle of filter of degree of depth type filter, has again suction-operated, this material for core has refill, sintering metal, felt and various fibers etc., be characterized in that manufacture is simple, filtering accuracy is high, filter core can bear high pressure, but metallic particles easily comes off, easy cleaning not after obstruction.
3, magnetic filter, magnetic filter mainly attracts iron filings and magnetic abrasive etc. by the magnetic field force of magnetic material.Filter core is made up of permanent magnet, can hold the abrasive dust of iron filings, iron powder or magnetic in fluid, often make composite type filter together with other form filter cores, to the machine tool hydraulic system particularly suitable of machined steel ironware, the feature of this filter comprises that deironing is good, high adsorption capacity, the convenient iron filings that clean, but, in use procedure, need frequent clean.
Hence one can see that, and at present, in conventional filter, ubiquity filtering accuracy is lower, easy cleaning or need the frequent shortcoming of changing not.
