The specific embodiment:

By Fig. 1～3 as seen, quantitative online drain filter, comprise and cover 2 and place the handwheel 1 of described lid 2 tops, housing 3 and the dirt storage room 6 and the blowoff valve 7 that place described housing 3 bottoms, it is characterized in that: described housing 3 is built-in with the upper mounted plate 16 and the bottom plate 17 of fixedlying connected with described lid 2 by strut 4, housing 3 inside are divided into inner chamber 12 and exocoel 11 two parts, be equipped with screen pack 20 in the middle of described upper mounted plate 16 and the bottom plate 17, described screen pack 20 can rotate synchronously with the central shaft 13 of fixedlying connected with handwheel 1, in the exocoel 11 of described housing 3, division board 10, hollow cylinder pillar 5, the collecting sewage reticular lamin 9 composition barrier assembly that is fixedly connected sequentially from top to bottom, described barrier assembly is connected with the lower end trapezoidal thread of central shaft 13, the top that isolates location-plate 8 is vertically installed with helical pitch plate 18, one side of helical pitch plate 18 is fixedlyed connected with housing 3, another side of described helical pitch plate 18 places in the semi-circular groove 21 of described division board 10 peripheries, described barrier assembly can move up and down along described helical pitch plate 18, be equipped with through hole 19 in the middle of the described isolation location-plate 8, division board 10 matches with the area size of described through hole 19.

High in the middle of described division board 10 is, low ramped shaped all around.Division board 10 peripheries are symmetrical arranged two semi-circular groove 21, and a side of described semi-circular groove 21 inner surfaces and described helical pitch plate 18 joins.

At least be equipped with a fixed head muscle 15 in the endoporus of described upper mounted plate 16 and bottom plate 17.Described handwheel 1 and described lid 2 are provided with corresponding graduated scale timberline 22.

During use, measured medium enters in the exocoel 11 from filter inlet under pressure, has been filter inner chamber 12 through entering behind the screen pack 20, flows out from filter outlet then.Dirt and impurity after filtering in this process are trapped on the screen pack 20, stopped up by dirt and impurity as screen pack 20, then the differential pressure at filter two ends increases, handwheel 1 and the graduated scale timberline 22 that covers on 2 need only align this moment, handwheel 1 forward rotation one circle, backward rotation one is enclosed then, be returned to graduated scale timberline 22 positions, rotate handwheel so repeatedly 1 three to five times, in this process, handwheel 1 drives screen pack 20 and rotates, fixed head muscle 15 on the bottom plate 17 scrapes the dirt and the impurity that are trapped on the screen pack 20, by the dirt that scraped and impurity the self gravitation effect drop to be positioned at below on the division board 10 because division board 10 surfaces in the middle of being high around low slope, enter the measured medium of exocoel 11 at this moment from filter inlet, dirt on the division board 10 and impurity had souring, dirt and impurity are washed away the passage between division board 10 and housing 3, through hole 19 in the middle of the isolation location-plate 8 flow in the dirt storage room 6 of filter bottom.

Pressure reduction as the filter two ends increases once more, can not make it to reduce with said method, illustrate that then dirt storage room 6 is full, at this moment, alignment handwheel 1 and the graduated scale timberline 22 that covers on 2 rotate handwheel 1 and drive central shaft 13, central shaft 13 can drive barrier assembly on helical pitch plate 18, move downward, rotate handwheel 1 till commentaries on classics is motionless, write down the number of turns of handwheel 1 rotation.Barrier assembly moves downward in this process, because dirt, impurity and the measured medium of this moment mix, collecting sewage reticular lamin 9 is assembled dirt and impurity downwards in the process that moves downward, thereby the concentration of dirt and impurity is increased, when division board 10 with after through hole 19 on isolating location-plate 8 overlaps, can reach quantitative effect this moment the dirt that will discharge and Control of Impurities in dirt storage room 6, open blowoff valve 7 at this moment, onlinely finish blowdown, filter can recover operate as normal.

After blowdown is finished, according to the number of turns of the handwheel write down 1 rotation, reverse rotation handwheel 1, until with the aligned position of the graduated scale timberline 22 that covers, barrier assembly rises and returns to the origin-location.In the process that barrier assembly resets, have certain pressure differential between dirt storage room 6 and the exocoel 11, the dirt and the impurity that utilize this pressure differential to be deposited in the blowdown process on the division board 10 wash away, and whole process is all online to be finished, need not termination of pumping, do not influence production.As special circumstances such as dirt and impurity are more, can unclamp bonnet bolt 14 take out in core assembly clean.

Quantitative online drain filter has solved the user in the blowdown process, and the difficult problem of uncontrollable blowdown flow rate is a process that blowdown is quantized, and is simple to operate, saved the energy, reduced consumption.
