Description

A kind of scroll rain water filtering device

Technical field

This utility model is related to a kind of defecator, specifically a kind of scroll rain water filtering device.

Background technology

Rain water filtering device is exactly to cross in filter fly in rainwater-collecting, and a kind of equipment of depth-type filtration is carried out to rainwater.Existing skill Rain water filtering device structure in art is relative complex, installs inconvenient, and cannot directly be filtered in rain water collecting system, The installation in later stage safeguards relatively complicated, during use to have inconvenience more.

The content of the invention

The purpose of this utility model is to provide a kind of scroll rain water filtering device, to solve above-mentioned background technology in propose Problem.

For achieving the above object, this utility model provides following technical scheme：

A kind of scroll rain water filtering device, including filter body, rainwater water inlet, rainwater outlet and sewage draining exit, it is described Filter body is the internal closing cylinder with cavity, and the side of the filter body opens up rain water inlet and row Dirty mouth, is installed with the single filter net and cascade filtration net for being socketed into double annular shapes, wherein rainwater water inlet in filter body It is interconnected with the cavity being placed in the single filter net of internal ring, sewage draining exit is placed in the opposite side of rainwater water inlet, and with one Cavity in level drainage screen and cascade filtration net is interconnected, and the position of sewage draining exit is less than rainwater water inlet, the diameter of sewage draining exit Less than rainwater water inlet, the side of filter body is further opened with rainwater outlet, rainwater outlet and cascade filtration portion off the net Cavity be interconnected.

As further program of the utility model：Net of the mesh diameter of the single filter net more than cascade filtration net Eye diameter, preferably, the mesh diameter of single filter net is 1mm, the mesh diameter of cascade filtration net is 0.5mm.

As this utility model further scheme：The inside of the cascade filtration net is provided with fountain head, and fountain head leads to Piping is connected with the outside water source that rinses.

As this utility model further scheme：The shell of the filter body adopts PE material injection molding, Single filter net and cascade filtration net are made using stainless steel.

Compared with prior art, the beneficial effects of the utility model are：Filter, blowdown utilizes rainwater baffling, gravity automatic Operation；It is furnished with the stainless steel filter screen of high precision, lighter region is polluted the water standard of reclaimed water can be directly reached； Can arbitrarily increase or directly buried, install simple, convenient, the later stage need not be safeguarded substantially.

Specific embodiment

The technical scheme of this patent is described in more detail with reference to specific embodiment.

Refer to Fig. 1-3, a kind of scroll rain water filtering device, including filter body 1, rainwater water inlet 2, rainwater outlet 4 and sewage draining exit 3, the filter body 1 is the internal closing cylinder with cavity, and the side of the filter body 1 is opened It is provided with rainwater water inlet 2 and sewage draining exit 3, filter body 1 and is installed with the single filter net 5 and two grades for being socketed into double annular shapes Drainage screen 6, wherein rainwater water inlet 2 are interconnected with the cavity being placed in the single filter net 5 of internal ring, and sewage draining exit 3 is placed in rain The opposite side of water water inlet 2, and be interconnected with the cavity in single filter net 5 and cascade filtration net 6, the position of sewage draining exit 3 Set low in rainwater water inlet 2, the diameter of sewage draining exit 3 is less than rainwater water inlet 2, and the side of filter body 1 is further opened with rainwater Outlet 4, rainwater outlet 4 is interconnected with the cavity of the bottom of cascade filtration net 6, enters into from rainwater water inlet 2 in rainwater In filter body 1, after the double filtration of single filter net 5 and cascade filtration net 6, the impurity in rainwater is trapped, Jing Rainwater after filtering flows out from rainwater outlet 4, because the position of sewage draining exit 3 is less than rainwater water inlet 2, is retained down Impurity can be washed away by the rainwater come in from rainwater water inlet 2, be flowed out from sewage draining exit 3.

The mesh diameter of the single filter net 5 is more than the mesh diameter of cascade filtration net 6, preferably, single filter The mesh diameter of net 5 is 1mm, and the mesh diameter of cascade filtration net 6 is 0.5mm, and dual step filters the mistake that can lift drainage screen The workload of filter effect and mitigation drainage screen.

The inside of the cascade filtration net 6 is provided with fountain head 7, and fountain head 7 is connected by pipeline with the outside water source that rinses, mistake In long-term work, single filter net 5 and the last time of cascade filtration net 6 adhere to impurity to filter body 1, and now fountain head 7 can enter Row water spray is rinsed to impurity, solves the blockage problem of single filter net 5 and cascade filtration net 6.

The shell of the filter body 1 adopts PE material injection molding, single filter net 5 and cascade filtration net 6 to adopt Made with stainless steel.

Operation principle of the present utility model is：Enter in filter body 1 from rainwater water inlet 2 in rainwater, Jing Guoyi After the double filtration of level drainage screen 5 and cascade filtration net 6, the impurity in rainwater is trapped, and the rainwater after filtration is from rainwater Outlet 4 flows out, and because the position of sewage draining exit 3 is less than rainwater water inlet 2, the impurity being retained down can be by from rainwater water inlet 2 rainwater come in are washed away, and are flowed out from sewage draining exit 3, and rainwater roll filter adopts gravity stream principle, and continuously rainwater is carried out Separating and filtering, its simple structure, is skillfully constructed, and fundamentally solving general purpose filter cannot be straight in rain water collecting system Take over the problem of filter, it is ensured that under filtration condition, it is unattended, do not block, not backwash, filter it is smooth.

The better embodiment of this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party Formula, in the ken that one skilled in the relevant art possesses, can be with the premise of without departing from this patent objective Make a variety of changes.
