Description
Technical field
The present invention relates to filter plant field, in particular to a kind of automatic backwash lubricating filtering device.
Background technology
The effect of filter is solid sundries removings such as the iron oxide be contained in filter medium, dust, reduces mechanical wear, guarantees the filter of main process equipment stable operation.
At present, domestic and international filter can be divided into surface type, degree of depth type and magnetic filter by filtering material.They to the filtration of solid pollutant by directly stopping and having adsorbed.
1, surface filter, is almost all stopped the side in filter element surface upstream by the particulate pollutant of filtering.Material for core has and demarcates aperture uniformly, filtering can be greater than the solid particle demarcating aperture.The filter belonging to this class has edge type, net formula and chip; Such filter feature is that structure is simple, 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 pervious material, and inside has tortuous roundabout passage.The contamination particle being greater than aperture is directly stopped at the outer surface by fluid upstream, and less particle is when entering filter core inner passage, owing to departing from a fluid stream by the effect of surface tension (Molecular Adsorption power, electrostatic force etc.), 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, have suction-operated again, 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, not easy cleaning after blocking.
3, magnetic filter, magnetic filter then mainly attracts iron filings and magnetic abrasive etc. by the magnetic field force of magnetic material.Filter core is made up of permanent magnet, the abrasive dust of the iron filings in fluid, iron powder or magnetic can be held, 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 except ferrous is good, and high adsorption capacity, conveniently cleans iron filings, but, in use procedure, need frequent clean.
It can thus be appreciated that at present, in conventional filter, ubiquity filtering accuracy is lower, the shortcoming of not easy cleaning or the frequent replacing of needs.
