The specific embodiment
As shown in Figure 1, a kind of filtering tank that the utility model provides comprises a tank body 2, is provided with inlet 16 on the top of this tank body 2, and its bottom is provided with liquid outlet 91, is provided with filtration system and anti-inflation, recoil water system in this tank body 2.
Filtration system comprises the filter that is arranged between this tank interior inlet 16 and the liquid outlet 91, and it comprises a tapering plate 5, a material-blocking device 13 and a filtrate.Tapering plate 5 is fixed in filtering tank inside, bigger awl mouth is provided with downwards, the material-blocking device 13 that the multilayer orifice plate is formed is equipped with in the 5 top vertex of a cone perforates of tapering plate on the aperture and in the following tapering plate, the filtrate (not shown) of many microporous particles shape is housed below the filtering tank internal taper plate 5; On liquid outlet 91, be provided with the orifice plate 7 that is used to intercept filtrate;
Anti-inflation, recoil water system comprise some anti-gas tubes 11, also comprise recoil water pipe 15, the air inlet of anti-gas tube 11 stretches out in tank body 2 outsides and is connected with source of the gas, its gas outlet is plugged in the filtrate, each anti-gas tube is divided into some groups according to the position of its gas outlet in tank body, and the horizontal level of the gas outlet of every group of anti-gas tube in tank body is with vertically highly different; One group of anti-gas tube can comprise an anti-gas tube, also can comprise some anti-gas tubes.The import of recoil water pipe is set in the bottom of tank body 2, this import can with liquid outlet 91 together; On tapering plate 5, be provided with slag-drip opening 4 on tank body 2 walls of correspondence bottom.Manhole 1, overfall 3 can also be installed on filtering tank top.
Some anti-gas tubes that are equipped with in the described filtering tank, gas outlet height can divide three layers of layout on it in filtrate, is distributed in top 2/3rds parts of filter material layer.Because can there be more filter residue on the top at filtrate, and following filter residue is fewer and feweri, in following 1/3rd height filter material layers, have filter residue hardly.Anti-gas tube is provided with highly lower, can be poor to the degree of floating of filtrate, and reach and float degree preferably, just need to consume the more energy, the air-flow of elevated pressures is provided.According to discovering, the gas outlet of anti-gas tube is arranged on can reach in 2/3rds height above the filtrate floats effect and energy-conservation all reasonable effect.
Filter screen is preferably wrapped up in upper end, gas outlet at anti-gas tube, results in blockage in order to avoid filtrate enters in the anti-gas tube.
The height of described filtrate is preferably lower than the lower end awl mouth of tapering plate.Reserve enough spaces for its boiling of filtrate in backwash, also avoid filtrate that material-blocking device is stopped up.
Material-blocking device 13 is formed by polylith orifice plate or net sheet are superimposed.
Between the top liquid level control switch 14 can be housed on tapering plate 5 and the filtering tank.
Native system is used for the solution that contains suspended contamination is carried out the on-line filtration reuse, and described tapering plate 5 is equipped with at the filtering tank 2 inner middle parts of going up, and a described material-blocking device 13 of being made up of the multilayer orifice plate is equipped with on tapering plate 5 tops.A plurality of valves 10 are housed in this control cabinet 6, can control the break-make of each anti-gas tube respectively.The upper end of anti-gas tube 11 is surrounded by filter screen 12.Be provided with liquid outlet 91 at 2 ends of tank body, on liquid outlet 91, connect drain pipe 9 and blow-off pipe 8 which is provided with valve.Between the top described liquid level control switch 14 is housed on tapering plate 5 and the cascade filtration jar 2.It can be a liquid level sensor.Be used for monitoring of the duty conversion such as for example keying of the liquid level of filtering tank with control feed liquor delivery pump.
Filtering tank is when work, pending liquid enters from inlet 16, behind material-blocking device 13, enter tank body 2 again, after granular filter material filters, flow out from liquid outlet 91, orifice plate 7 can stop that filtrate flows out with being filtered liquid, during anti-the inflation, open the valve 10 of anti-gas charging system, open the recoil water system simultaneously, recoil water enters in the tank body from the below by liquid outlet 91 from recoil water pipe 15, gas blows afloat the filtrate in the tank body, under the flow action of the recoil water that rises, be embedded floating with the filter residue that is bonded on the filtrate between the filtrate, from the duct of material-blocking device 13, pass through, go up in the tank body space above tapering plate 5, water velocity is slack-off, and filter residue is deposited to above the tapering plate 5, and assembles along slag-drip opening 4 places that slide under the inclined-plane of tapering plate on the periphery.Owing to have the anti-gas tube 11 of group more than many in the anti-gas charging system that the utility model provides, can in filter process, open some anti-gas tubes, for example anti-ventilating control valve 10 is opened on a part of one group one group ground, the part of filtrate is floated, filter residue wherein rises and promptly this part filtrate is carried out backwash by rising to above the tapering plate from material-blocking device 13, and the part filtrate of not opening anti-inflation to filter as usual, the material-blocking device 13 of filter residue from the tapering plate 5 flows out during backwash, and filtrate is stopped by material-blocking device 13 and do not lose filtrate.After this filtering tank filters several order of classes or grades at school, can close inlet during intermittence in operation, open recoil water pipe 15 and anti-charging valve 10 and carry out backwash simultaneously.Filter residue is discharged from slag-drip opening 4.
Anti-gas tube gas outlet in anti-gas charging system is arranged on differing heights in the filtrate, diverse location, gas can impact slagging-off in the enforcement everywhere of filtrate in the recoil process, and slagging-off is thorough, in addition, can loosen everywhere to filtrate, therefore, the filtrate in this filtering tank does not harden, does not stop up, favorable regeneration effect, and such compressed air adds the backwash that water carries out, energy consumption is lower, and discharge capacity is littler.Have again, because the gas outlet of anti-gas tube is positioned on the diverse location, by some blast pipes of selectively unlocking, can be so that a part of filtrate carry out backwash in the tank body, and the filtrate of other parts still filters.The utility model provides the structure of the anti-gas charging system in the filtering tank to can be implemented in blowback part filtrate in the filter process, can guarantee the eliminating of the loose and filter residue that filtrate is real-time like this, is the characteristics that existing filtering tank never has.
Can also comprise a conveyer belt type filtering device, described conveyer belt type filtering device filters as one-level, and filtering tank is as cascade filtration, and the liquid outlet of conveyer belt type filtering device connects by pipeline through tubing pump with the inlet of filtering tank.
Described conveyer belt type filtering device is shown in Fig. 2,3,4,5.The liquid outlet of described conveyer belt type filtering device connects by pipeline through tubing pump with the inlet of filtering tank; Described conveyer belt type filtering device, it comprises conveyor type filter screen 106 and lautertuns 101, tilting conveyor type screen pack 103 in the lautertuns 101, this screen pack 106 is connected with a transmission mechanism, make this screen pack turn round, lautertuns 101 1 sides are equipped with ash pit 102, at filter screen 106 back sides one deslagging device 107 are housed on the top, and inlet, liquid outlet are housed on lautertuns 101.
