Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of the utility model;
Fig. 2 is the overlooking structure diagram of Fig. 1;
Fig. 3 is the A-A of Fig. 1 to structural schematic diagram.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.
With reference to attached drawing 1-3, the utility model provides a kind of technical solution: a kind of back flush type water filter, including drainage shell Body 1 is equipped with partition 9 in drainage shell 1, and drainage shell 1 is divided into lower intake chamber 7 and upper filter chamber 3 by partition 9, in drainage The lower part of shell 1 is equipped with the water inlet 8 being connected to lower intake chamber 7, and the water outlet being in the same center line with water inlet 8 5, water inlet 8 and water outlet 5 are symmetricly set on the two sides of drainage shell 1.It is equipped in lower intake chamber 7 and is connected to water outlet 5 It is discharged chamber 6, water outlet chamber 6 is connected to upper about 3 filter chamber.
Filter assemblies 11 are equipped in upper filter chamber 3, filter assemblies 11 are biased to 8 side of water inlet and are arranged in upper filter chamber 3 In, the filter assemblies 11 include deviateing 1 central axis of drainage shell, vertically arranged pivoted frame 10, and pivoted frame 10 deviates drainage shell 1 central axis 100mm of body.It is equipped with the motor 2 that driving pivoted frame 10 rotates above drainage shell 1, lower ending opening is housed on pivoted frame 10 The screen tube of upper end closed, the interior divides that pass through of screen tube are at 8 filter elements 15.The screen tube include upper cover plate and Cylindrical filter screen, upper cover plate are connected with pivoted frame 10, and the filter element 15 is sector structure.
Inhalant region 16, blowdown backwash area 14, the total partition of surface area Zhan of the inhalant region 16 are provided on the partition 9 The 66% of 9 surface areas.Partition 9 on inhalant region 16, inside each filter element 15 is equipped with to be connected to lower intake chamber 7 Filling pipe end 12, filling pipe end 12 be sector;It is set in blowdown backwash area 14, on the partition 9 inside each filter element 15 There is sewage draining exit 13.
There are two types of the blowdown schemes, a kind of are as follows: sewage pipe to be connected on the sewage draining exit 13, the other end of sewage pipe is stretched Drainage shell 1 out.
It is another are as follows: blowdown room to be equipped in the lower intake chamber 7, blowdown room upper end is connected to sewage draining exit 13, in drainage shell Body 1 is equipped with the sewage pipe being connected in blowdown room.
It is equipped with arc the cover 4 in the outside of drainage shell 1, the upper and lower ends of arc the cover 4 are closed, under arc the cover 4 It holds and flushes setting with the bottom of water outlet chamber 6, the upper end of arc the cover 4 connects with upper 3 top of filter chamber, and the water outlet 5 is set On the cambered surface central axis of arc the cover 4.
In use, arriving lower intake chamber 7 by the water inlet of water inlet 8, and enter the mistake from inhalant region 16 from filling pipe end 12 Filter in unit 15, water enters upper filter chamber 3 through filtering by the cylindrical filter screen of screen tube, rear water purification be flowed into water outlet chamber 6 from Water outlet 5 flows out.When pivoted frame 10 drives screen tube rotation, after rotating to blowdown backwash area 14, screen tube bottom is not into Water, at this moment without water in filter element 15, under the hydraulic pressure effect in upper filter chamber 3, filtered water purification passes through cylindrical filter screen Cylindrical filter screen is backwashed, into each filter element 15, sewage is discharged from sewage draining exit 13.In addition because filter assemblies 11 are eccentric Setting, so the water in the upper filter chamber 3 in blowdown backwash area 14 is big, backwash effect is good.
