Special advantage

1. because the special construction of mesh wire cage has realized that filametntary spacing property is evenly arranged in the filtering layer, so that clean operating mode The therapeutic method to keep the adverse qi flowing downward, water mixed flow can clean to every filament, do not stay any blind area. Overcome the ball center blind area of fibrous nodules Pencil constraint blind area with fibre bundle.

2. because the structure of gas-vapor mix device 3, distribution device 2 belongs to the evacuation structure, do not increase any resistance in filtration flow-rate. Adjust the percent opening of regulating orifice plate 7, the control resistance to water-flow can arbitrarily be regulated it to the compaction of fiber.

3. when filtered water circulation filter course, fiber is to water generates dynamic resistance pressure head, and this pressure head is accumulated increase from top to bottom. Because Filtering material is flexible, thereby filtering material produces flexible compression when the accumulation of dynamic resistance pressure head increases, and density gradually Increase, make filtering layer form the desirable structure of filtering layer of hole gradual change by filtering direction.

4. because upper screen cloth 6 adopts flexible structure to be connected with regulating orifice plate 7, so when the filtering layer flexible compression, upper screen cloth 6 can With Free Transform, thereby can automatically adjust the bulk density of filtrate, make it more even, not produce Biased flow phenomenon.

Cage type filter of the present invention adopts gas-vapor mix, subregion dual mode cleaning way when cleaning, can realize powerful clear Wash.
