Whole filter core is installed in the coaxial aperture of median septum 10 and lower clapboard 17.

Below that the course of work division of filter core excessively of the present utility model is as follows:

Cellulose filter element filtering process: when residual cake valve 27 cuts out, piston 20 moves up under spring 18 effects, drives by connecting rod 14 and goes up circle 15 and flap 12 moves up, and at this moment cellulose 16 is tightened up, and flap 12 leaves with valve seat 13.Muddy water reaches the muddy water chamber by water inlet 18, enter inner barrel by cylindrical shell 9 top apertures, water hole by valve seat 13 and last circle 15 enters into cellulosic inner chamber again, and the aperture that passes cellulose 16 and cylindrical shell 9 middle parts again enters the clear water chamber, sends by delivery port 31 at last.Water promptly is filtered.

Cellulose filter core backwash process: open when residual cake valve 27, the deslagging chamber is linked to each other with atmosphere, piston 20 lower end decompressions at this moment, piston 20 moves down under the effect of body pressure, and this just makes the mud hole of cylindrical shell 9 bottoms link to each other with the deslagging chamber.Under connecting rod 14 drives, on enclose 15 and move down, cellulose 16 is loosened, flap 12 covers valve seat 13.At this moment the aperture of the water in clear water chamber by cylindrical shell middle part passes cellulose 16 and reaches the cellulose inner chamber.Pass through the deslagging chamber again, again by plug valve, scum pipe 26, residual cake valve 27 is discharged in the atmosphere, and this just makes cellulose 16 obtain cleaning.

The filter process of turn filter core: when residual cake valve 27 cuts out, piston 20 and down circle 19 under spring 18 effects, move up (at this moment piston 20 and down circle 19 be fixed together), on enclose 15 motionlessly, at this moment turn 41 is compacted, muddy water reaches exocoel from the turn inner chamber, and water promptly is filtered.

Turn filter core backwash process: when residual cake valve 27 is opened, piston 20 and down circle 19 under the effect of body pressure, move down, turn 41 is loosened.Cylindrical shell 9 bottom mud holes are linked to each other with the deslagging chamber.The water in clear water chamber reaches inner chamber by the turn exocoel, is discharged in the atmosphere through deslagging chamber, plug valve, scum pipe 26, residual cake valve 27 again, and at this moment turn 41 obtains cleaning.

Flexure strip is crossed the filter process of filter core: close when residual cake valve 27, the spiral arm valve is outwarded winding, and muddy water enters into the filter core inner chamber, enters into the clear water chamber by the slit between activity template 33 and the stator 32 again, sends by exporting 31, and water promptly is filtered.

Flexure strip is crossed the backwash process of filter core: when residual cake valve 27 is opened, the spiral arm valve is screwed into filter core place suitable for reading, sealed body 37 suitable for reading is sealed, filter core inner chamber decompression, at this moment the clear water in clear water chamber oppositely passes through the slit of stator 32 and activity template 33, enter into the deslagging chamber by slag-drip opening 28, be discharged in the atmosphere by plug valve and scum pipe 26, residual cake valve 27 again.Filter core promptly is cleaned.

The utility model advantage is: rational in infrastructure, can carry out backwash automatically, the easy cleaning and regeneration of filter core.The filtering accuracy height, applied range.Can be used for the filtration of water, beverage and beer.

Press the structure of accompanying drawing, the explanation of this specification the 5th part is processed, is assembled and can implement the utility model.
