Referring to Fig. 1-5, one group of filter tank of the present utility model is made of several filter tanks usually.Each filter tank is two and independently all presses cavity, is double-deck centre gangway in the centre of two cavitys, makes the filter tank form about two two lattice filter chambers 26.Porous plate 27 is equipped with in the bottom of each filter chamber 26, and the filter chamber is divided into two parts up and down, and top adds the filtrate 15 that is made of fibre bundle, and is fixed on the porous plate 27 with several equally distributed various known water caps 28.

For the ease of the cleaning of filtering layer with improve filter effect,, the compression chamber 16 of a plurality of even layouts is arranged on the whole cross section in filtering layer according to the principle that CN87100467 discloses.The pressurization of compression chamber can realize by special compression chamber's filling and drainage system (not shown).

The upper strata of middle channel, filter tank is a backwash drainage ditch 7, and lower floor is that gas, moisture are joined canal 8.One deploying gas aperture 10 is arranged at the top of canal 8 two sides, and a deploying water aperture 9 is arranged at the bottom.A upper lateral part has former water channel 1, distribution channel 3 outside the filter tank.Water intaking valve 2 is arranged on the dividing plate between former water channel 1 and the distribution channel 3 and laterally sweep and wash inlet opening 24.Filter tank water inlet V-type groove 13 is arranged on side walls top, filter tank, have a horizontal row to wash aperture 14 to sweeping at the bottom land of V-type groove 13.On the sidewall between distribution channel 3 and the V-type groove 13, be provided with V-type groove water inlet 23.

In the another side, filter tank piping lane 25 is arranged, air pipe line 12 and backwash water pipe 21 are arranged in piping lane 25.

Backwash water discharging valve 4 is arranged at a distolateral wall bottom in the backwash rhone 7 on top, middle channel, so that drainage ditch 6 links to each other with backwash rhone 7.Joining canal 8 one distolateral wall bottoms at gas, moisture has and just washes water discharging valve 5, so that canal 8 links to each other with drainage ditch 6, the top of other end sidewall links to each other with air duct 29 with air door 12 by pipeline, links to each other with backwash water pipe 21 with clear water pipe 19 with backwash inlet valve 22 by branch pipe tee connection, Clean water valve 20 in lower sidewall.

Clear water pipe 19 communicates with trapped well 18.In trapped well, be provided with dividing plate 30, clear water weir 17 arranged on the top of dividing plate 30.Be clear water canal 11 under piping lane 25, outside the dividing plate 30 of trapped well 18, have through hole 31 to communicate with clear water canal 11.

The course of work of the present utility model is:, to compression chamber's 16 water-fillings filtering layer is pressurizeed by compression chamber's filling and drainage system.Filtering layer is under the effect of compression chamber 16, and density strengthens gradually along the mobile direction of water, forms the in-depth filtration effect.The former water that is filtered enters V-type groove 13 by former water channel 1, water intaking valve 2, distribution channel 3 and V-type groove water inlet 23.Former water covers the groove top of V-type groove 23, flows into equably in the filter chamber 26.After former water is filtered by filtering layer, join in the canal 8 through porous plate 27, air distribution hole 10, distributing hole 9, the gas, the moisture that are focused on the bottom, middle channel.Open Clean water valve 20, the clear water that is filtered enters in the trapped well 18 by clear water pipe 19, Clean water valve 20.Adjust the height on the clear water weir 17 on trapped well 18 internal partitions 30, make the filter tank keep suitable filtering cloth head and filtering velocity.Clear water flows into clear water canal 11 by clear water weir 17, the through hole 31 of trapped well 18.

When the contaminated needs of filtering layer clean, close Clean water valve 20.Start compression chamber's filling and drainage system, discharge the water in the compression chamber, loosen filtering layer 13.Make filtrate be in free state.

Just wash

Open water intaking valve 2 and send water, open and just wash draining valve 5, form and just wash to the filter tank.At this moment, rinse water enters filter chamber 26 by former water channel 1, water intaking valve 2, distribution channel 3, V-type groove water inlet 23, V-type groove 13.After filtering layer cleaned, sewage joined by gas, moisture that distributing hole 9 on canal 8 sidewalls enters into gas, moisture is joined canal 8, is discharged in the drainage ditch 6 by just washing draining valve 5 again.

After just washing end, close water intaking valve 2, just wash draining valve 5, finish just to wash.

Backwash

Open back flush valves 22 and send water, open backwash draining valve 4 and carry out the backwash draining to the filter tank.At this moment, backwashing water distributes the distributing hole 9 on canal 8 sidewalls to enter the filter chamber by air water.After rinse water is cleaned filtering layer, be collected in the backwash rhone 7, simultaneously, water in the former tank 1 on top, filter tank still has on a small quantity and washes water inlet 24 by laterally sweeping, V-type groove water inlet 23 enters V-type groove 15, enter filter chamber 26 by the hole flushing 14 of laterally sweeping on the V-type groove 15 again, 26 the water surface produces lateral current in the filter chamber, forms laterally to sweep to wash the backwash rhone 7 in the middle of the impurity on the water surface, dirt are pushed to.Then, backwashing water is discharged in the drainage ditch 6 by backwash draining valve 4.

When filtering layer carries out positive and negative washing, can carry out air bump rinse operation to filtering layer.At this moment, start air blast, open air door 12, scavenging air distributes the air distribution hole 10 on canal 8 sidewalls to be input in the filter chamber by air water by air duct 29, air door 12 again.During backwash, in the filter chamber.When just washing, air and rinse water form convection current, can give full play to the characteristics that air water is cleaned, and can effectively clean filtrate.

In addition, porous plate 27 is equipped with in the bottom of filter chamber 21, and up-hole plate is equipped with on top, has several evenly distributed apertures on up-hole plate.Be fixed on the porous plate 27 adding get one's things ready filtrate 15 and water cap 28 between two orifice plates, the other end of filtrate is fixed on the up-hole plate.Also can increase drawing plate on up-hole plate top, up-hole plate and drawing plate are for being rigidly connected.A plurality of non-return valves are housed on drawing plate.A plurality of guiders are housed on orifice plate.21 top is provided with overflow mechanism in the filter chamber.Up-hole plate and drawing plate can move vertically along guider together.The move mode of up-hole plate can be the move mode of the orifice plate that disclosed of CN2138518, CN1232712 or Chinese patent application 98201424.4, and the orifice plate move mode in these applications can be used as embodiment of the present utility model.The structure of filter chamber 21 is also applicable to other forms of gravity filter equipment such as conventional rapid filters.
