Description
Technical field
The present invention relates to purification technology field, more particularly to a kind of new fore filter.
Background technology
Fore filter is first of the coarse filtration equipment to full room water, can filter the silt in running water, iron rust,
Large particulate matter.After being typically mounted on inlet channel water meter, to ensure that caused a large amount of precipitated impurities will not be to human body in pipe network
Damage, and positive protective effect is played to concealed pipe, tap, electrical equipment etc..
Currently there are three kinds of fore filters, be respectively it is positive rinse fore filter, siphon fore filter and
Fore filter is backwashed, wherein, the flushing flow rate of positive flushing fore filter is big, and for bulky grain foul, developing result is good,
But current flushing filtering net surface is only leaned on, for adhering to the stronger foul on filter screen, effect is bad, it is difficult to rinses out；Rainbow
Fore filter is inhaled, for the strong attachment foul on screen pack, filth-discharging effect is preferable, but sewage discharge tube must be with screen pack distance very
Closely, otherwise, the weaker effect of negative-pressure sucking is bad.Bulky grain foul hardly enters drain outlet, therefore big again when closer to the distance
Grain thing is easily deposited on row in filter bottle and not gone out；Backwash fore filter outwards punching inside screen pack using current
Wash, it is preferable for the strong attachment foul on screen pack, filth-discharging effect.But current are smaller when backwashing, for bulky grain foul
Developing result, just rinsed not as preposition rapid.
Therefore, the filter effect of fore filter how is improved, is those skilled in the art's technical problem urgently to be resolved hurrily.
