On two sealant end faces of film silk root, be respectively arranged with the elastomer protective layer, in the elastomer protective layer that has solarization air cap sealant one end, be provided with sealant in corresponding solarization air cap.The height of protective layer is 5-100mm.The material of described elastomer protective layer is any in polyurethane, silicon rubber, the flexible alkyd resin.
Described collector pipe two ends are respectively arranged with tongue and groove with corresponding sealant junction.
The material of described collector pipe is metal or plastics.
Described putamina is made up of putamina main body and connected sieve tube, sieve lid, is respectively arranged with a plurality of inlet openings on described putamina main body and sieve tube.
The present invention has following technique effect:
1. external-pressing film assembly of the present invention combines the advantage of column-type film components and curtain type film assembly, and the film silk is installed in the putamina; and perforate on putamina; can be applicable in the immersion environment that putamina has played the effect of diaphragm silk, prolong the service life of assembly.And, not high to water quality requirement, can handle the water source of most of water quality, easy to use.
2. external-pressing film assembly of the present invention inside is equipped with collector pipe, adopts double water outlet end, has maximally utilised film silk effective area, compares with same membrane area external-compression type assembly, and aquifer yield increases more than 20% on year-on-year basis.
3. owing to adopt negative pressure suction mode, with the column-type film components method of operation mutually specific energy consumption significantly reduce, use and maintenance cost reduces.
4. adopt the immersion operation principle lower, saved project initiation and use cost environment and maintenance requirement.Simultaneously easier for installation, quick, be convenient to the workmen and manipulate.
5. external-pressing film assembly of the present invention adopts the second pouring mode, carries out the protective layer cast again after promptly pouring into a mould sealant, because film silk root is protected, has avoided the generation of assembly film silk fracture of wire, has further prolonged the service life of assembly.
