Embodiment

The two-way two-net filter is installed in the middle of two flanges of pipeline, and after the liquid operation, can not work simultaneously in the A chamber 1 and the B chamber 4 of filter; During as 1 work of A chamber, close B chamber inlet 5 and B chamber liquid outlet 6 with feed liquor valve handle 15 and liquid valve handle 16 control feed liquor spools 12 and fluid spool 14, open A chamber inlet 2 and A chamber liquid outlet 3, liquid flowed into from feed tube 31 and entered A chamber 1 through A chamber inlet 2 this moment, and the coarse filtration of the one-level screen pack 9 on the rack 8 and the thin filtration of cascade filtration net 10 enter drain pipe 32 after A chamber liquid outlet 3 flows out after filtration again; During as 4 work of B chamber, close A chamber inlet 2 and A chamber liquid outlet 3 with feed liquor valve handle 15 and liquid valve handle 16 control feed liquor spools 12 and fluid spool 14, open B chamber inlet 5 and B chamber liquid outlet 6, liquid flowed into from feed tube 31 and entered B chamber 4 through B chamber inlet 5 this moment, and the coarse filtration of the one-level screen pack 9 on the rack 8 and the thin filtration of cascade filtration net 10 enter drain pipe 32 after B chamber liquid outlet 5 flows out after filtration again; The mesh order number of one-level screen pack 9 and cascade filtration net 10 when using in the pipeline flowing liquid medium decide; The fluid flow that flows through left and right limit filtering holes 34 equals to flow through the fluid flow of A chamber inlet 2 and A chamber liquid outlet 3 respectively; When the screen pack in the A chamber 1 is stopped up by slag or foreign material, elder generation is with A chamber inlet 2 in the blocked A chamber 1 and A chamber liquid outlet 3 usefulness feed liquor valve handles 15 and feed liquor spools 12 controlled by liquid valve handle 16 and fluid spool 14 is closed, meanwhile B chamber inlet 5 and B chamber liquid outlet 6 are opened and make the 4 participation work of B chamber, like this, under situation about not stopping production, just can overhaul blocked A chamber 1; During maintenance, at first the turn clamping screw 24, on carry and open and push down the pressing plate 25 that filters rack 8, unscrew the nut on the screw rod 22 again, spurring arm-tie 23 laterally from the support bar 21 shifts out clamping screw 24 and pressing plate 25, taking out filtering frame cleans or draping, after cleaning or the draping, again filtering frame is inserted in the cavity, and pressing plate 25 rotated to the top of filtering rack 8, the upper port of alignment filter rack 8 slowly firmly screws off clamping screw 24 pressing plate 25 is compressed again, seals, and opens when stopping up in order to another cavity again; When the screen pack in the cleaning B chamber 4, also equally operate by the screen pack program of cleaning in the A chamber 1; The base bottom of two working chambers of two-way two-net filter is separately installed with

blowoff valve

29,30, emits in order to the slag foreign material with deposition; On the feed tube 31 and drain pipe 32 of two-way two-net filter, should be according to operating pressure setting pressure table, so that observe the pressure difference of importing and exporting both sides at any time, when the pressure loss during greater than 0.07Mpa, the expression screen pack is existing to be stopped up than large tracts of land, at this moment should in time clean screen pack.

The structure that adopts two-way, two net, cascade filtration, fast-open type is gone up in the utility model design, reaches the journey that do not flow backwards, and does not shut down, has not only saved the energy, improves filter effect, but also can Rapid Cleaning removes the purpose of slag foreign material.
