Description
Technical field
The utility model relates to a kind of filter for blow-off line, but relates to specifically a kind of filter of automatic slag removal.
Background technology
General sewage treatment plant is before sewage enters sewage disposal system, grid is set in the capital or filter screen is held back suspension thicker in the sewage or floating thing, prevent these materials obstructions and winding water pump assembly, aerator, pipeline valve, processing structures intake-outlet, reduce subsequent treatment and produce waste residue, guarantee the normal operation of sewage treatment facility.But aborning, the waste residue of holding back on grid or the filter screen also needs to clear up timely.
Mainly contain at present two kinds of scarfing cinder modes, a kind of is the labor cleaning, and another kind is mechanical chipping.It is less that the labor cleaning is only applicable to scale, the sewage treatment plant that waste residue is less, and when processing poisonous and hazardous sewage, also can damage the healthy of scarfing cinder personnel.Although and general mechanical chipping cleaning amount is large, also be applicable to poisonous and hazardous environment, also exist equipment complicated, investment is large, the defectives such as Maintenance Difficulty.
Summary of the invention
But the purpose of this utility model provides a kind of filter of automatic slag removal, has advantages of simple in structure, small investment, easy care.
The technical solution adopted in the utility model is: comprise a three-way pipeline with inlet, leakage fluid dram and slag-drip opening, in the three-way pipeline of leakage fluid dram inboard, filter screen is housed, the three-way pipeline inner chamber is separated into admission chamber and exhaust chamber, and leakage fluid dram and slag-drip opening are equipped with respectively magnetic valve; The electric contact differential manometer is housed on the three-way pipeline, and two probes of differential manometer are separately positioned in the admission chamber, exhaust chamber of filter screen both sides.
Differential manometer is used for measuring the filter screen both sides along the pressure differential on the water (flow) direction, and opens and closes according to the magnetic valve on pressure differential control discharge outlet and the slag-drip opening.When pressure differential reaches the capping value, the closed electromagnetic valve on the discharge outlet, the magnetic valve of slag-drip opening is opened, and sewage is discharged by slag-drip opening, reaches the purpose of automatic slag removal.When pressure differential was reduced to preset lower limit, the magnetic valve on the discharge outlet was opened, and the closed electromagnetic valve of slag-drip opening keeps hull-borne.
Consider the flushing cinder effect of current in the tapping process, described filter screen is inclined in the three-way pipeline, and the angle that filter screen additionally arranges direction and inlet symmetrical centre is 40 °～50 °, and filter screen additionally arranges the angle of direction and slag-drip opening symmetrical centre less than 45 °.The current that flowed into by inlet can wash away screen surface preferably, thereby waste residue is broken away from from filter screen, along with current are discharged by slag-drip opening.
A preferred version of the present utility model is: inlet and leakage fluid dram symmetrical centre overlap, and the angle that filter screen additionally arranges direction and inlet symmetrical centre is 45 °, and it is parallel with the slag-drip opening symmetrical centre that filter screen additionally arranges direction.It is larger that current wash away strength to screen surface, and when the current scour screen surface and after changing the original flow direction, water (flow) direction and filter screen are laid direction and discharged by slag-drip opening abreast, the suffered resistance of deslagging is less, and deslagging is more thorough.
As shown from the above technical solution, the magnetic valve that the utility model adopts differential manometer to control leakage fluid dram and slag-drip opening opens and closes, and by changing the direction of current, the force direction that is subjected to of the waste residue that is blocked in screen surface is changed, and reaches the purpose of waste residue Automatic clearance.The filter apparatus configuration of this differential automatic slag removal is simple, invests littlely, does not need manual inspection, is easy to regular maintenance.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is another example structure schematic diagram of the utility model.
The specific embodiment
The utility model structure comprises a three-way pipeline 1 with inlet 11, leakage fluid dram 12 and slag-drip opening 13 as shown in Figure 1, and leakage fluid dram 12 and slag-drip opening 13 are equipped with respectively magnetic valve 5,7; The filter screen 4 that is obliquely installed is housed in the three-way pipeline 1 of leakage fluid dram 12 inboards, and the angle that filter screen 4 additionally arranges direction and inlet 11 symmetrical centre is 40 °～50 °, and filter screen 4 additionally arranges the angle of direction and slag-drip opening 13 symmetrical centre less than 45 °.Filter screen 4 is separated into admission chamber 14 and exhaust chamber 15 with three-way pipeline 1 inner chamber.Electric contact differential manometer 3 is housed on the three-way pipeline 1, and two of differential manometer 3 probes 31,32 are separately positioned in the admission chamber 14, exhaust chamber 15 of filter screen 4 both sides.Differential manometer 3 is used for measuring filter screen 4 both sides admission chambers 14, exhaust chamber 15 along the pressure differential on the water (flow) direction, and opens and closes according to the magnetic valve 5 on pressure differential control discharge outlet 12 and the slag-drip opening 13,7.Piece number 2,6 is respectively adpting flange among Fig. 1.
Above-mentioned inlet 11 and leakage fluid dram 12 symmetrical centre can overlap, also can be not point-blank.The former can reduce pipeline flow resistance.
Its operation principle is as follows: when pressure differential reached the capping value, the magnetic valve 5 on the discharge outlet 12 cut out, and the magnetic valve 7 of slag-drip opening 13 is opened, and sewage is carried the waste residue of screen surface secretly and drained by pipeline 8, reaches the purpose of automatic slag removal.When pressure differential was reduced to preset lower limit, the magnetic valve 5 on the discharge outlet 12 was opened, and the magnetic valve 7 of slag-drip opening 13 cuts out, and was discharged by discharge outlet 12 through the current of filter screen 4, kept hull-borne.Because it is 40 °～50 ° that filter screen 3 additionally arranges the angle of direction and inlet 12 symmetrical centre, the current that flowed into by inlet 11 can wash away filter screen 4 surfaces preferably, and waste residue is broken away from from filter screen, and along with current are discharged by slag-drip opening 13.
Another embodiment as shown in Figure 2, the angle that filter screen 4 additionally arranges direction and inlet 11 symmetrical centre is 45 °, it is parallel with slag-drip opening 13 symmetrical centre that filter screen 4 additionally arranges direction.Adopt this structure, current are larger to filter screen 4 surface erosion strength, and when the current scour screen surface and after changing the original flow direction, water (flow) direction and filter screen additionally arrange direction and discharged by slag-drip opening abreast, and the suffered resistance of deslagging is less, and deslagging is more thorough.
