Shown in Fig. 1,3,4, a kind of single film hole aeration filter head that is used for BAF comprises hollow simple pit filter handle 1, pre-buried filter ruffle 2 and filter cap 3.Simple pit filter handle 1 is connected by the internal thread 2-2 of its outside screw 1-1 and built-in fitting 2; Built-in fitting 2 is fixed on the filter plate by concrete casting; Filter cap 3 is connected with the internal thread 2-1 of built-in fitting 2 by its outside screw 3-1.The aperture of the air distribution hole 1-1 of simple pit filter handle 1 is ￠ 2～3mm, and 50～200mm distance in top is provided with aeration fenestra device 1-3, and this aeration fenestra device 1-3 is positioned at the beneath side of filter plate 50～150mm; The below of air distribution hole 1-5 is provided with distribution seam 1-6, stitches wide 2mm, the long 30～50mm of seam.
As shown in Figure 2, the aeration fenestra device 1-3 of simple pit filter handle is made up of solarization air cap 1-3-1, single hole rubber diaphragm 1-3-2 and the perforate cover plate 1-3-3 that is used for fixing this rubber diaphragm.The aperture of the fenestra of solarization air cap 1-3-1 and single hole rubber diaphragm 1-3-2 is respectively ￠ 2～3mm and ￠ 1～1.5mm, and the aperture of the perforate of perforate cover plate 1-3-3 is not less than 3mm.Solarization air cap (1-3-1) only is connected with filter handle outside by the fenestra of single hole rubber diaphragm (1-3-2) and the perforate of perforate cover plate (1-3-3).
The aeration fenestra device of simple pit filter handle is preferably as follows a kind of in three kinds of devices; certainly also be not limited only to following three kinds of devices, every scope that all belongs to the utility model protection by solarization air cap 1-3-1, single hole rubber diaphragm 1-3-2 and the perforate cover plate structure that 1-3-3 forms that is used for fixing this rubber diaphragm.
(1) inwall of simple pit filter handle 1 is cylindrical, the outside that penetrates filter handle wall at solarization air cap 1-3-1 is an one flat plate, perforate cover plate 1-3-3 is the clinching cover plate, just as film-type boring aeration pipe (application number: 200710027903.9) the used perforate cover plate that has back-off, clinching is located on the head slab of solarization air cap 1-3-1, dull and stereotyped upper end is the grooved space to cover plate top board lower end, single hole rubber diaphragm 1-3-2 is positioned at the grooved space, and the rubber diaphragm upper end keeps 2～5 mm distance with perforate cover plate top board 1-3-3 lower end.
(2) inwall of simple pit filter handle 1 is cylindrical, the outer periphery that penetrates filter handle wall at solarization air cap 1-3-1 is provided with screw thread, perforate cover plate 1-3-3 is a bottle cap type threaded hole cover plate, solarization air cap 1-3-1 and the engagement of bottle cap type threaded hole cover plate, single hole rubber diaphragm 1-3-2 is located in the bottle cap type threaded hole cover plate.
(3) inwall and the outside of simple pit filter handle (1) are cylindrical, solarization air cap (1-3-1) penetrates filter handle wall, perforate cover plate (1-3-3) is pipe clamp and fixed ring, two pipe clamps are fixed on single hole rubber diaphragm (1-3-2) on the cylindrical simple pit filter handle (1), and wherein a slice is that the perforate pipe clamp pastes mutually with single hole rubber diaphragm (1-3-2).Upper and lower end at pipe clamp respectively is inserted in a fixed ring, makes pipe clamp and fixed ring become a fixed integral body.
Because be subjected to the influence of construction factor, fixedly the levelness between the filter air distribution hole does not often reach processing requirement, causes distribution even inadequately.The utility model finally makes all the aeration fenestra device 1-3 in the same filter tank be on the same horizontal plane by passing through on screw thread 1-1 and the 2-2 accent between simple pit filter handle 1 and the built-in fitting 2 or transferring down, and the height error is no more than ± 1mm.Thereby realize even distribution for filter handle 1 and created necessary condition.
When BAF was normally moved, pending water entered in the BAF water and air distributing district from water inlet pipe, upwards flowed through a kind of simple pit filter handle 1 and filter cap 3 that is used for the single film hole aeration filter head of BAF; The aeration air enters the water and air distributing district of BAF from aeration tube, under filter plate, form stable air cushion layer, enter in the filter handle 1 from each a kind of aeration fenestra device 1-3 that is used for the single film hole aeration filter head of BAF and to mix, lead to filter cap 3 then and enter in the filtrate supporting layer and filter material layer of BAF with water.Be enough to guarantee that in gas-water ratio whole aeration fenestras are positioned under the condition of air cushion layer, each is a kind of, and to be used for the aeration rate of single film hole aeration filter head of BAF basic identical, can guarantee the homogeneity of aeration; BAF adopts combined water and air backwash, the back flushing air enters the water and air distributing district of BAF from the back flushing tracheae, under filter plate, form stable air cushion layer, a small amount of back flushing air enters in the filter handle 1 from aeration fenestra device 1-3, overwhelming majority back flushing air then is (to stitch wide 2mm from ￠ 2～3mm air distribution hole 1-5 and distribution seam 1-6, seam long 3～5mm) enters in the filter handle 1, mix with water then after filtration that cap 3 enters the filtrate supporting layer and the filter material layer of BAF, so the back flushing tolerance of each filter is basic identical; Normal water purification or backwashing water enter the water and air distributing district of BAF from water inlet pipe or back flushing water pipe, inlet and distribution seam 1-6 thereof through simple pit filter handle 1 enter in the filter handle 1, flow through through filter cap 3 with air mixed, enter in the filtrate supporting layer and filter material layer of BAF.Because a kind of single film hole aeration filter head that is used for BAF is a small resistance water wiring system, so the water distribution quantity of each filter is basic identical.Therefore, can guarantee the homogeneity of aeration, water distribution and back flushing air distribution and water distribution.
The aeration head of aerating filter adopts the form of single hole rubber diaphragm usually, and generally about 5 years, be significantly less than the work-ing life of filtrate its work-ing life.In addition, because the strong disturbance the when long-time running in filter tank and back flushing, the aerating system in the filter tank is worn easily, pipe occurs splitting, displacement, problems such as obstruction.Therefore, not only pipeline is many for aerating system in the present pond of BAF, and investment is many, installs complicatedly, and the maintenance aerating system need all dig out filtrate in the body of pond, and workload is huge, and recondition expense is also high.Therefore, the maintenance of aerating system is a key issue in the pond of aerating filter.Aeration fenestra device 1-3 of the present utility model is positioned at the water and air distributing district under the filter plate, retainer between simple pit filter handle 1 and the built-in fitting 2 is installed also below filter plate, can arrive fault aeration fenestra device 1-3 by manhole, clean, change single hole rubber diaphragm 1-3-2 and even change filter handle 1, compare with the aerating system in being installed in the filtrate supporting layer, service work is simplified greatly, and the cost of overhaul significantly reduces.Significantly reduce the investment and the maintenance cost of aerating system in the filter tank.
