Background technology
Fore filter is first of coarse filtration equipment of purified water, silt, iron rust and the glue being mainly used in water removal
The granule foreigns such as body, play the role of pre-filtered.After being typically mounted on inlet channel, to ensure a large amount of precipitations produced in pipe network
Impurity will not damage human body, and positive protective effect is played to concealed pipe, tap, electric appliance etc..Preposition mistake
Filter is the jinx of secondary pollution, is a kind of reliable device for filtering impurities.
It is that maximum feature is that current are reversely removed contamination to backwash fore filter, will be attached to the particle in strainer from strainer
Develop.When filter needs to rinse trapped substance, commutation multichannel in itself that manually or automatically carried by adjusting filter
Valve realizes the reverse of current, raw water current is achieveed the purpose that recoil from the water purification effluent of strainer (core) to raw water side.Stream at present
Capable is hydrocone type backwash, is rinsed more thorough.But some dirts are adhered on strainer than stronger, backwash is removed contamination cannot
It is fully apparent from, it is necessary to which the surface physics of strength scrapes.
Utility model content
The purpose of this utility model is that there are the above problem for existing technology, it is proposed that a kind of fore filter, can
Efficiently to remove contamination, remove contamination comprehensively.
The purpose of this utility model can be realized by following technical proposal：A kind of fore filter, including housing, end
Lid, support plate and filter screen set, it is characterised in that housing upper end opening, support plate block the opening in housing, end cap with housing
End snaps connection, and end cap has water inlet pipe and outlet pipe, and strainer is set in housing and is connected with support plate, opened in support plate
There is the water inlet of connection water inlet pipe and housing cavity, connection outlet pipe and the water outlet of filter screen set inner cavity are provided with the middle part of support plate；
Shaft is rotatably connected in support plate, shaft upper end is connected with the impeller in end cap, and connection strap is fixed with shaft, connection
Spiral scraping article is fixed with bar, spiral scraping article mutually reclines with filter screen set inner wall, and shaft lower end stretches out filter screen set and is connected with outer scrape
Frame, scrapes the hairbrush for having on frame and leaning with filter screen set outer wall outside.
During normal work, water is flowed into from water inlet pipe, is entered by water inlet in housing, current are from the outer wall of filter screen set to filter
The center of net cover is penetrated into, and is filtered during infiltration by filter screen set, and the current filtered are flowed out from water outlet, enter end cap
Discharged in outlet pipe.Since the current through water outlet are perpendicular to impeller, so impeller does not rotate.
When removing contamination, back to fore filter water filling, water is flowed into from outlet pipe is horizontal, the impeller under the action of current
Rotate, impeller drives shaft to rotate, and shaft drives spiral scraping article to scrape filter screen set inner wall, and shaft drives outer frame of scraping to scrape filter screen set
Outer wall, the dirt on filter screen set inside and outside wall is scraped off, and dirt can flow out water inlet pipe with reverse flow on filter screen set outer wall, and
Dirt on filter screen set inner wall can be flowed out from outlet pipe in normal hour with positive current.Remove contamination inside and outside filter screen set comprehensively,
Convenience and high-efficiency.
Further, step is equipped with the shell nozzle, support plate is stuck on step.
Further, scraping frame outside includes the base in crosswise and the floating rule for being vertically connected on base outer end, and hairbrush is connected
On the inside of floating rule.
Further, there is sleeve, shaft is caught in sleeve fixed on base.
Further, also it is fixed with hairbrush on the base.
Further, the central axes of the outlet pipe and the axial line of shaft are vertical but non-intersect.This set makes to draw
The current that water pipe enters can be crashed on impeller, impeller is rotated to same direction.
Compared with prior art, this fore filter has the spiral scraping article that can scrape filter screen set inside and outside wall and scrapes outside
Frame, drives shaft to rotate by reverse flow, so that the dirt on filter screen set can be scratched, it is simple efficient, without
Dismounting, use are very convenient.
