Filter head, filter cap, filter head skillet, skillet filter cap structure; filter head, filter cap, filter head skillet, skillet filter cap is simple, reliable technology, small head loss, low energy consumption, no dead zones, plot mud clogging, easy construction management, filter backwash water is only 1/2 to 1/3 of the traditional anti-clogging skillet filter head, and when the backwash air first enters the filter plate bottom with the water district and the formation of cushion layer, When the cushion layer gradually thickened when the lower air intake filter handle and a long strip sewn to the air intake, a lot of air into the filter handle it, and out of the cut surface of the particle filter flushing filter head from the gap, caused by pollution in quality the upper layer of the filter, the water vapor while flushing filter micro-expansion, proper scrub. Since the filter in the filter head screw head to strengthen the structure, the addition of rubber gaskets, securely connected, not falling, design bottom seam of the water, additional protection measures such as anti-clogging filter characteristics to solve the entire filter flushing uneven. Filter head, filter cap, skillet filter head, filter cap advantage skillet; rinse uneven filter will have the following consequences: ① wash some areas of low intensity. Because of the trapped particulates filter runtime section, part of colloidal particles by adsorption of biological flocculation, while microbial biofilm metabolic process of aging after shedding will also trapped in the bio-filler. The presence of these impurities can significantly increase the bio-filter filtration resistance; but also to make the mass transfer efficiency of the water body dissolved oxygen and biological easily degradable organic matter and microbial biofilm between the decline; the impact of the removal of organic matter biofilter efficiency. ② irrigating large skillet stainless steel filter head strength areas, as a result of excessive water velocity filter head filter cap manufacturers, will impulse supporting layer, causing mixed biological filter and supporting layer, and even lead to the loss of bio-filler, sometimes will cause loose gas distribution system, for BAF cause great harm and other issues. Features adjustable filter attempts to prevent head: blockades adjustable filter head filter plate used in conjunction with the whole cast, especially for the water to the V-filter, filter flap and BAF sewage treatment on both solve the problem of clogged filter head, but also solve the filter plate sealing performance is poor, the problem of low intensity, but also to solve the technical difficulties installing the filter head Plates level difficult to achieve. 1, with both ends of the filter cap structure under bidirectional filter head, sewage in the SS is the next filter cap closure, but completely solved easily clogged filter head hidden; 2, having the filter rod adjustment function, a fundamental solution to the Plates in the whole cast or installation process due to irregularities caused by the intake inconsistent risks; attempts to prevent the type of filter head BAF dedicated technical requirements specification data; ⑴ blockades type BAF special filter head with filter cap from the filter rod, embedded casing and attempts to prevent the filter cap composition, embedded casing embedded in the concrete filter plate, and with an internal thread, filter plate thickness 100mm. (2) filter head, filter tubes and embedded casing properties are consistent with the provisions of "drinking water compared with standard equipment and safety evaluation of protective materials" GB / T17219 in. (3) high pressure filter head promise, stepped touch is not broken, reliable connection, after installation shall ensure that the head does not fall off the filter. (4) between the filter head and filter plate should be no dead zones, do not plug the plot mud. (5) attempts to prevent the type of filter head BAF special quality inspection standards; filter head gap should be no defects, fly edges and burrs, filter head surface should be smooth, no impurities, no crack filter head, no bubbles, consistent surface color, James shiny surface, the product without flexing phenomenon, no shrinkage, no less than material phenomenon. According to specifications, is not greater than ± 0.1mm.
