Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, this utility model is described in detail.
With reference to Fig. 1, a kind of backwash filter, including filter body 1, it is arranged on the sewage draining exit 28 at filter body 1 top, it is disposed in parallel in the water inlet 2 bottom filter body 1 and outlet 3, is arranged on the element kit in filter element body 1, be arranged on filter body 1 power motor 4 for driving element kit to work, connecting lead screw shaft 23 on power motor 4, lead screw shaft shell 24 is provided with the travel switch 16 for limiting screw axis position.
During real work, water is entered by water inlet 2, first passes around coarse strainer 5 and filters out the impurity of larger particles, then arrives fie screen assembly, filtered off by less granule foreign further from water.In filter process, fie screen assembly builds up the booty in water, impurity, forms impurity screening layer, and owing to impurity layer is deposited in the inner side of fie screen assembly, therefore the medial and lateral at fie screen assembly are the formation of a pressure reduction.
When preset value during this pressure reduction reaches common pressure reduction indicator, will start automatic cleaning process, now water purification supply is not interrupted；Blowoff valve 20 is opened and is discharged by water；Hydraulic pressure in backwash chamber 21 and dirt sucking tube 6 significantly declines, and produces a soil pick-up process from there through suction nozzle 9, and discharged by blowoff valve 20 between dirt sucking tube 6 and backwash chamber 21.Meanwhile, power motor 4 drives dirt sucking tube 6 to rotate vertically, and dirt sucking tube 6 axially-movable and the combination of rotary motion drive soil pick-up unit to be cleaned up completely by whole filter screen inner surface.Soil pick-up cell rings is located at the dirt sucking tube whole body, and soil pick-up unit includes for the fixed interface 7 that be connected fixing with dirt sucking tube 6, the telescopic joint 8 being arranged on fixed interface 7, the suction nozzle 9 being arranged on telescopic joint 8.When dirt sucking tube drives soil pick-up unit axially-movable and axially-movable with sheathed rotating brush, can be cleaned up by rotating brush, improve cleaning effect on suction nozzle 9.
If filter water inlet 2 and the pressure reduction of outlet 3 keep constant, backwash process will persistently be carried out.If through the time being pre-designed, pressure reduction keeps constant, and urgent backwash valve 18 also will be opened, and now blowoff valve 20 and urgent backwash valve 18 are simultaneously in open mode.Now, the time that backwash process will persistently pre-set.After pressure reduction reduces, two blowoff valves 20 and urgent backwash valve 18 are all closed.Power motor 4 arrives in connecting shaft and quits work at travel switch 16.System begins preparing for next flushing cycle, and the water purification after filtration is flowed out by outlet 3.
With reference to Fig. 6, element kit includes: is arranged on the coarse strainer 5 at water inlet 2 and is connected the fie screen assembly arranged with coarse strainer 5, and the dirt sucking tube 6 being arranged in fie screen assembly, described dirt sucking tube 6 whole body is equipped with some soil pick-up unit, described soil pick-up unit includes for the fixed interface 7 that be connected fixing with dirt sucking tube 6, the telescopic joint 8 being arranged on fixed interface 7, the suction nozzle 9 being arranged on telescopic joint 8.
With reference to Fig. 4, fie screen assembly includes: in the middle part of fie screen top 10, fie screen 11 and fie screen bottom 12；Described fie screen top 10 and fie screen bottom 12 are socketed in the middle part of fie screen 11 respectively, and port is provided with filter screen handle 12；Described fie screen bottom 12 is arranged at outlet 3.
With reference to Fig. 5, fie screen assembly includes: in the middle part of fie screen top 10, fie screen 11 and fie screen bottom 12；In the middle part of described fie screen top 10, fie screen 11 and fie screen bottom 12 be socketed setting the most successively.
With reference to Fig. 3, screw component includes: screw axis 23, the screw axis shell 24 being set in outside screw axis 23, be arranged at screw axis shell 24 one end by screw screw axis after shield 25, be arranged at the rear capsul 26 of screw axis shell 24 other end by black box, and be arranged at the screw axis side wall guard board 27 of screw axis shell 24 side.
Coarse strainer 5, fie screen assembly use stainless steel metal filter screen to be made, and are fixed in filter body by hoop longitudinal direction press strip respectively, it is ensured that maximum filtering area, and have rigidity and the intensity of enough resistance to deformations.
The above is only preferred implementation of the present utility model, and protection domain of the present utility model is not limited merely to above-described embodiment, and all technical schemes belonged under this utility model thinking belong to protection domain of the present utility model.It should be pointed out that, for those skilled in the art, without departing from the some improvements and modifications under this utility model principle premise, these improvements and modifications also should be regarded as protection domain of the present utility model.
