Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technical side in this utility model embodiment
Case is clearly and completely described, it is clear that described embodiment is only that this utility model part is real
Execute example rather than whole embodiments.Based on the embodiment in this utility model, ordinary skill people
The every other embodiment that member is obtained under not making creative work premise, broadly falls into this utility model
The scope of protection.
A kind of gravity type valveless water filter device embodiment as shown in Figure 1, Figure 2 and Figure 3, including on tank body 1
Distributor box 8, rhone 13 and siphoning installation, siphoning installation includes siphon tedge 9, the rainbow being sequentially connected with
Inhale down-comer 12 and auxiliary siphon tube 10, siphon tedge 9 and auxiliary siphon tube 10 stretch into tank body 1 inside,
Connect bottom auxiliary siphon tube 10 and have siphon destructive bucket pipe 11；Connect on siphon tedge 9 and have water inlet pipe 6,
Tank body 1 is internal is provided with drainage tube 7 and outlet, and tank body 1 is internal is from bottom to top provided with gathering ground 2, filtering area
4 and clear water zone 5, it is provided with activity filter bed 3 between gathering ground 2 and filtering area 4；Activity filter bed 3 include support,
Filtrate and the water filter plate combined by some drainage unit 31, drainage unit 31 includes shell 32, shell
32 surround the drainage trap 33 of some equalizations by its internal cross wall and longitudinal wall, and drainage trap 33 is provided with some
Shape treatment hole 34.Drainage unit 31 is rectangle；The crisscross arrangement for the treatment of hole 34 on adjacent drainage trap 33.
Filtrate is arranged on water filter plate, and it includes gravel layer, quartz sand and the anthracite coal measure set gradually from the bottom to top.
Gravel layer thickness 100～300mm, quartz sand thickness 200～350mm, anthracite coal measure thickness 250～400mm.
Strip treatment hole wide 0.3～1mm, long 15～50mm.The cross section at drainage tube 7 top is trapezoidal.Drainage list
Unit 31 makes for ABS engineering plastics.
Work process of the present utility model is: during work, and former water enters nothing from water inlet pipe 6 under gravity
In valve filter tank body 1, subsequently into filtering area 4, filtering area 4 is provided with activity filter bed 3 and filtrate, then leads to
Cross filter course and enter back into gathering ground 2, now owing to there is activity filter bed 3, owing to current are through water filter plate,
Current are slowed down and uniform distribution by the some drainage traps 33 in each drainage unit 31, and current pass through drainage trap 33
Interior strip treatment hole is even into filtrate, and due to water inlet uniformly, thus without breaking up filtrate, filtrate can be all
Even distribution, does not haves dead angle, so backwashing water even water distribution.The turbidity such as the float in former water are cut
Staying and adsorb in the surface and filter material layer of filter material layer, the water entering gathering ground 2 is the clear water after filtering.Clear water
Before filter with filter after under two liquid level potential difference effects or under former effect of water pressure, enter from bottom to top from gathering ground 2
Clear water zone 5, then the drainage tube 7 at top is overflowed into from clear water zone 5, it flow to water outlet along drainage tube 7 by outlet
Pipe.Owing to drainage tube 17 top cross-section is trapezoidal, so being greatly accelerated out water speed.Along with holding of filtering
Continuous carrying out, retain and the turbidity such as the float adsorbed gradually increases in filter material layer, turbidity penetrates filtration the most successively
Layer enters gathering ground 2 and clear water zone 5, and the resistance of media filtration is also gradually increased simultaneously, and the rate of filtration is the most gradually
Reducing, former water liquid level in siphon tedge 9 is also gradually increasing, when reaching the highest water surface, and valveless mistake
Filter is immediately automatically into backwash process.When the water surface in clear water zone 5 is down to the siphon destructive bucket mouth of pipe 11,
Air enters the top of inverted siphon down-comer 12 from the siphon destructive bucket mouth of pipe 11, and then siphon is destroyed,
Backwashing water cutout in siphoning installation, backwash terminates.Meanwhile, the filtrate being in swelling state falls,
Former water still enters filtering area 4, has started the most again the filtration work in a cycle.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model,
All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all
Within protection domain of the present utility model should be included in.
