Description
Technical field
The utility model is related to a kind of water purification device, it is particularly a kind of running water is tentatively filtered it is preposition net
Hydrophone.
Background technology
With social progress and the improvement of people's living standards, domestic water quality turns into problem of concern.Due to
By different degrees of pollution, existing tap water supply processing system also fails to completely to reach water quality to compare reason natural water quality
The requirement thought, it is larger a considerable amount of silts, iron rust, suspension, parasite equidimension to be still present in life running water
Impurity, these large granular impurities are not only unsuitable for drinking, and are also unfavorable for the normal of appliance water such as washing machine, water heater, boiler
Work, easily these service lifes for losing these household electrical appliances.So first of water purification handled with water of family expenses can be set
Standby is very necessary.Existing water purification filter product generally require often to change filter core, it is necessary to periodically carry out maintenance clean but
Often it is not easy to observe interiors of products situation again, even needs professional to carry out clean and maintenance work, usage experience is unsatisfactory.
Utility model content
First of basic filtering work is carried out to household tap water in order to realize, and filter plant is overcome often
Filter core is changed, be not easy to safeguard and the normality shortcoming such as clean, a kind of fore filter of the utility model offer, by more high-precision
The stainless steel filter screen of degree is effectively filtered, while makes, in observation filter interior situation, to facilitate clean and maintenance.
Technical scheme is used by the utility model solves its technical problem：A kind of fore filter, including head, filter
Core, protective cover, sewage draining valve.
There is protective cover at middle part with being engaged above filter core on the outside of filter core below head；Protective cover upper shed engages with head, prevents
Shield under shed engages with sewage draining valve；There are frame of filter element and filter screen in filter core, frame of filter element is in tubbiness, its side hollow out, is filtered
Net makes of stainless steel, is wrapped in the side of frame of filter element, and the filter gap size on filter screen is at 40 microns to 60 microns
Between, it is possible to achieve effective filtering to visible particle；There are water inlet and delivery port, water inlet and sky inside protective cover on head
Between connect, delivery port connects with filter core inner space；There are drain outlet, connection protective cover inside and water purifier in the middle part of sewage draining valve
Outside, there is copper ball in drain outlet, copper ball controls closure or openness by knob.
Frame of filter element can be upper opening, closed downwards, the barrel-like structure of side hollow out, or top and side
Hollow out, lower opening, there is the structure of capping at lower opening.
Preferably, there is scale inhibition ball inside filter core, scale inhibition ball is made with the scale inhibition material such as Si-P crystal.
Preferably, protective cover makes of transparent material.
During normal work, sewage draining valve is closed, and raw water is injected in protective cover from water inlet, inside strainer filtering and filter core
The filtering of scale inhibition ball, flow to delivery port in the middle part of the filter core；During cleaning, sewage draining valve is opened, the filth in raw water scour protection cover
Thing, and dunghill is sent out through sewage draining valve.
The beneficial effects of the utility model are that the large scale impurity in running water was carried out by the filter screen of degree of precision
Filter, reach preferable preliminary treatment effect, while convenient observation filter interior situation and clean and maintenance work, it is fixed to remove from again
Phase changes the work of filter core.
