Description
Technical field
The present invention relates to a kind of fore filter.
Background technology
After fore filter is arranged on inlet channel water meter usually, to guarantee that a large amount of precipitated impurities produced in pipe network can not damage human body, and positive provide protection is played to concealed pipe, water tap, electrical equipment etc.
Mainly contain four kinds of fore filters in the market:
1, laminated filter, it is the groove that a large amount of micron-scale is carved with on very thin specific plastic laminate both sides, when the lamination of a string same isotype is pressed in and specially designed inner support is compressed by spring and liquid pressure, channels intersect between lamination, thus the filtering unit forming a series of 100 microns.Shortcoming: impurity rinses not thoroughly, filtering accuracy is uneven, do not have sewage draining exit.
2, along stamp fore filter, great majority adopt the stainless steel filtering net of 50-100um, penetrate into outer wall by the pressure water of tap water from the inwall of pipeline.Shortcoming: as during water quality inferiority or the custom of human consumer bad, filter core is easily blocked, and not only less impurity rinses not out, on the contrary in filter core embedding more deeply, tighter, easily form secondary pollution, housing can only be opened and filter core is brought out scrub with toothbrush.
3, siphonic fore filter, the inside is penetrated into from the outer wall of pipeline by the pressure of tap water, the granule foreign such as silt, iron rust, red worm is retained in surface by fenestra, open flush switch current around filter core, form secondary pressure, built-in water distributor more effectively can remove the dirt impurity that filter screen retains, the impurity being retained in film surface is cut to pieces in device by rain and is managed washed away, before comparing two is preposition, developing result will be got well a lot.Shortcoming: product structure is complicated, flushing is not thorough, impurity as more weaker in water-quality ratio in filter core embedding more deeply, tighter last filter core blocks, cause secondary pollution, get up very difficult once block maintenance, most of production hydrocone type product filtering accuracy is all more than 50 microns.
4, back flushing fore filter, outer wall is penetrated into by the inwall of filter screen by the pressure of tap water, the particulate contaminants such as silt, iron rust is retained in pipe, open flushing valve the impurity that retains by filter screen washed away, if run into, water-quality ratio is poor, human consumer does not rinse for a long time, has blocked and has not also worried.Make piston move to bottom by back flushing switch, the direction changing current transfers " external-compression type " to and is embedded in cartridge surface by the suitable impurity do not fallen in a state of excitement, and the water being reversed operation washes away.Shortcoming: back flushing fore filter is when back flushing, and the tap water do not purified enters the water purification side of filter screen, can cause the pollution of the water purification side of filter screen for a long time; Rinse also not thorough simultaneously.
Therefore, how to design a kind of good filtration effect, effectively prevent filter net jam and the fore filter of the long service life technical problem that to be industry urgently to be resolved hurrily.
