Description

The multi-level oil filter

The utility model relates to a kind of multi-level oil filter, is mainly used in purified tap water, well water, natural water etc., makes it directly to reach the standard of drinking water, and the essence filter that also can be used for drug extract separates.

Purifier of the prior art can be classified as following three kinds of situations:

Adopt the doughnut reverse osmosis unit to obtain high pure water, promptly so-called space water.Adopt active carbon, macromolecular compound, ion exchange resin materials such as (or adding magnetic mineralizing), single using or use in conjunction obtains higher pure drinking water in cascade filtration mode (one-in-and-one-out formula).Improve on the basis of the above, add slag-drip opening, carry out backflush process, to prolong filter core operating period, i.e. one-in-and-two-out formula.

Mainly by external import, price too high (more than 2～4,000 yuan) can't widespread usage for the doughnut reverse osmosis unit.And water outlet is slow, and the gained water purification is equivalent to distilled water, if people's long-term drinking can cause that some basic ions lack in the body.If spent ion exchange resin is made scavenging material, can not contained or contain less the water purification of ion at short notice, but its exchange capacity there is certain limit, must regularly carry out acid, alkali regeneration processing, the general user is difficult to grasp this technology.Along with the increase of number of processes, exchange capacity can descend gradually, even loses effectiveness.

In use because filter material is stopped up in the formation of secondary membrane (filter residue cake), and efficient reduces, bacterium is detained breeding and pollutes one-in-and-one-out formula water purifier, and the operating period is limited, must buy producer's filter core and change, and requiring of having changed in 1 year one.

One-in-and-two-out formula water-purifying device has had slag-drip opening, has overcome the problems referred to above to a certain extent, but its cleaning way all adopts backpulsing, and this just causes secondary pollution unavoidably, and the deslagging that has is not smooth, and cleaning performance is not good.

The purpose of this utility model is to design a kind of multi-level oil filter, can remove by filter all suspended impurities, pernicious gas, pathogenic bacteria etc. in the water, makes it to reach directly drinking standard; Deslagging immediately after the filtration easily and thoroughly, does not form secondary membrane (filter residue cake) on filter material, can keep the unobstructed of filter material and cleaning all the time, avoids bacterium to be detained breeding; Can wash inner filter membrane and filter material automatically, adopt Washdown type, pressure is big, and flushing is thorough, the non-secondary pollution phenomenon; Parts assemblings is flexible, and the user can change filter membrane, filter material and sorbing material certainly, also can be according to the emerging in large numbers of new material, and own update filter material and needn't exchange device, thus reach the purpose of long-term use.
