Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the utility model further, the present embodiment is implemented under premised on technical solutions of the utility model, should understand these embodiments and only be not used in restriction scope of the present utility model for illustration of the utility model.
As shown in figs. 1-7, a kind of detachable anti-clogging plug easy cleaning strainer head, comprises long handle filter bar 1, is sleeved on the filter service sleeve 2 on long handle filter bar 1 and protects the filter shield cap 3 at long handle filter bar 1 top; Long handle filter bar 1 is Whole-dismountable long handle filter bar.Wherein long handle is filtered between bar 1 and filter service sleeve 2 and is all connected by internal and external threads between filter service sleeve 2 and filter shield cap 3.
Long handle filter bar 1 comprises into water filter bar 4, and water inlet filter bar 4 lower end is water-in 5, and the outer wall of water inlet filter bar 4 is provided with inlet mouth 6, and be provided with dismountable water distribution filter cap 7 at the top of water inlet filter bar 4, water distribution filter cap 7 is positioned at filter shield cap 3.Inlet mouth 6 comprises air inlet port 8 and air inlet bar shaped seam 9, and air inlet port 8 is positioned at above air inlet bar shaped seam 9.Filter shield cap 3 is provided with the vertical V-arrangement seam 10 of some water distributions, and it is circumferentially uniformly distributed in the horizontal direction, and water wavelength width of a slit is 3.5mm excessively.
In I type detachable anti-clogging plug easy cleaning strainer head, I type water inlet filter bar internal diameter is φ 20.0mm, external diameter is that φ 25.0mm, I type water distribution filter cap wavelength width of a slit is 3.0mm, its lateral type gap number is 6.
In II type detachable anti-clogging plug easy cleaning strainer head, II type water inlet filter bar internal diameter is φ 21.5mm, external diameter be φ 26.5mm, II type water distribution filter cap wavelength width of a slit is 3.0mm, its vertical groove part gap number 13.
Working process:
1), when this product uses, middle part trunnion shape service sleeve is cast in concrete support filter plate 11 (abbreviation filter plate) in advance, and casing threads end should on filter plate;
2) filter plate is after engineering site installation, upwards installs long handle filter bar 1, clockwise turns to and install filter, is rotated counterclockwise as dismounting filter, screwed by fitting nut 13 bottom filter plate;
3) after the installation of long handle filter bar 1, from filter plate top, top protection cover is installed, clockwise turns to installation, be rotated counterclockwise as dismounting;
4) after the installation of long handle filter bar, filter tank water inlet runs, and current are intake from long handle filter bar bottom water-in 5, carry out water distribution uniformity by the water distribution filter cap 7 at top;
5), during filter tank is run, the impurity exceeding water distribution filter cap 7 water distribution wavelength width of a slit is trapped within filter cap, and the impurity through water distribution filter cap 7 gap can not be blocked in filter shield cap 3, because filter shield cap 3 wavelength width of a slit is greater than water distribution filter cap 1 wavelength width of a slit;
6) when there are abnormal conditions in filter tank operation long period or water quality, a small amount of impurity can be retained in water distribution filter cap 7 and filter shield cap 3, now only long handle need be filtered bar 1 to pull down, can clear up impurity in filter shield cap 3 easily, after dismounting, long handle filter bar 1 also can cleared up easily, clean;
7) filter shield cap 3 has been cleared up, long handle filter bar 1 clears up after cleaning completes, and long handle is filtered bar 1 follow procedure 2) install from filter plate bottom;
8), after the installation of long handle filter bar 1, normal operation can be recovered in filter tank.
This product solves following problem, and in actual use, water distribution filter cap and long handle filter bar are divided into I type and II type:
1, anti-blockage capability is improved:
A, according to BAF process application practical situation, have adjusted top water distribution filter cap structure formation, have adjusted water distribution wavelength width of a slit and quantity.Wavelength width of a slit is adjusted to 3.0mm, I type lateral type gap number is 6 (roads), II type vertical groove part gap number 13 (road), reduces the generation of latch up phenomenon while ensureing uniformity of water distribution.
2, cloth water resistance is reduced:
Have adjusted the inside and outside diameter into water filter bar, I type long handle filter bar internal diameter is φ 20.0mm, external diameter is φ 25.0mm, II type long handle filter bar internal diameter is φ 21.5mm, external diameter is φ 26.5mm, while guarantee uniformity of water distribution, reduce running resistance, reduce energy consumption, decrease and arrange density, ensure that filter-plate structure intensity.
3, clear up easy to maintenance:
1) have employed Whole-dismountable filter bar kit form, when needing cleaning after running longer for some time, carry out clearing up and more convenient after not needing long handle can be filtered the dismounting of bar assembly under filler and bed course situation in cleaning pond;
2) the top water distribution filter cap in long handle filter bar assembly takes Demountable, the impurity of easy cleaning trapped inside;
3) filter top takes protective roof structure form, top filler and bed course can not be caused to leak down after the dismounting of long handle filter bar assembly;
4) top protection cover adopts more scientific reasonably vertical V-type gap, and cross water wavelength width of a slit 3.6mm, namely wavelength width of a slit ensure that and not easily blocked by impurity, in turn ensure that filler bed course can not leak down;
5) service sleeve nut takes more reasonably structure formation, have adjusted internal whorl size, and I molded cannula screw thread specification is M45, II molded cannula screw thread specification is M48, and sleeve pipe total length is 100mm;
6) have adjusted service sleeve internal whorl restraint location, be locked and adopt lower end to be locked mode, conveniently to install and dismounting;
7) have adjusted service sleeve nut bottom hydraucone diameter, bottom I type, outside diameter is φ 75mm, and bottom II type, outside diameter is φ 80mm;
Not only 8) top and shield cap adopt thread connecting mode, ensure that and install firmly but also facilitate construction and installation, and bottom I type shield cap, outside diameter is φ 75mm, outside diameter is φ 80mm bottom II type shield cap.
