Abstract
The utility model discloses a special aerator of a biological aerated filter. The special aerator is composed of multiple aeration units which are detachably connected in series, wherein the aeration units comprise air inlet branch pipes, upper pipe clamps, lower pipe clamps, fixing rings and multi-hole membranes; the upper pipe clamps and the lower pipe clamps are semi-cylindrical and are respectively adhered to the upper and lower sides of the air inlet branch pipes, and the left and right ends of the upper pipe clamps and the lower pipe clamps are respectively locked by virtue of one fixing ring; the air inlet branch pipes and the upper pipe clamps are provided with aeration holes which are communicated, the multi-hole membranes are arranged between the upper pipe clamps and the lower pipe clamps and can cover the aeration holes formed in the air inlet branch pipes; the multi-hole membranes are provided with multiple air outlets. The special aerator provided by the utility model has the advantages that the air distribution is uniform, a problem that the whole aeration units are disabled because one of the holes is blocked is effectively avoided, the service life is effectively prolonged, and the aeration air bubbles are tiny, so that the oxygen transfer efficiency of the air in the water is high, and the operation cost is saved.
Description
Technical field
The utility model relates to a kind of special-purpose aerator of BAF.
Background technology
See Fig. 1, the aeration head that is of the aerator of common BAF adopts hole membranes, hole membranes aeration head is because certain service area only has a production well, in being easy to by biological filter in the long-play process of biological filter, dirt stops up, and cause in this aeration head coverage not having oxygen to supply with, if a plurality of aeration heads are blocked, easily cause whole aerator to damage.In addition, common aerator is to connect a plurality of aeration heads on a long pipeline, when one of them aeration head damages, changes very trouble.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of gas distribution evenly, long service life, the repair and replacement special-purpose aerator of BAF conveniently.
In order to solve the problems of the technologies described above, technical scheme provided by the utility model is: a kind of special-purpose aerator of BAF, is removably connected in series and forms by a plurality of aeration units; Described aeration unit comprises air intake branch, upper pipe clamp, lower tube clip, fixed ring and porous membrane; Described upper pipe clamp and lower tube clip are semi-cylindrical shaped, and are fitted in respectively the both sides up and down of air intake branch; Lock by a fixed ring respectively at the two ends, left and right of described upper pipe clamp and lower tube clip; Described air intake branch and upper pipe clamp are provided with the solarization air cap communicating; Described porous membrane is arranged between pipe clamp and air intake branch, and covers the solarization air cap on air intake branch; Described porous membrane is provided with a plurality of air outlets.
Air outlet on the porous membrane of described aeration unit is strip.
Described aeration unit also comprises screw nipple; Described air intake branch and screw nipple are respectively arranged with internal thread and outside screw; One end of described screw nipple is connected with the threaded one end of air intake branch; The other end of described screw nipple is connected with the threaded one end of the air intake branch of another aeration unit.
Adopted after technique scheme, the utlity model has following beneficial effect: (1) porous membrane of the present utility model is provided with a plurality of air outlets, not only make gas distribution more even, effectively avoided because of a blocked problem that whole aeration unit was lost efficacy in hole, effectively extended work-ing life, and the bubble exposing is more small, make the oxygen transfer efficiency of air in water higher, save running cost.
(2) aeration unit of the present utility model adopts screw-type link, and repair and replacement are more convenient.
Accompanying drawing explanation
For content of the present utility model is more easily expressly understood, according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein below
Fig. 1 is the structural representation of common aeration head.
Fig. 2 is the structural representation of aeration unit of the present utility model.
Label in accompanying drawing is:
Air intake branch 1, upper pipe clamp 2, lower tube clip 3, fixed ring 4, porous membrane 5, air outlet 51, screw nipple 6.
Embodiment
(embodiment 1)
The special-purpose aerator of the BAF of the present embodiment is removably connected in series and forms by a plurality of aeration units.See Fig. 2, aeration unit comprises air intake branch 1, upper pipe clamp 2, lower tube clip 3, fixed ring 4, porous membrane 5, screw nipple 6.
Air intake branch 1 and screw nipple 6 are respectively arranged with internal thread and outside screw.One end of screw nipple 6 is connected with the threaded one end of air intake branch 1.The other end of screw nipple 6 is connected with the threaded one end of the air intake branch of another aeration unit 1.The link of this screw-type, repair and replacement are more convenient.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
