400kg's, be highly 200mm, and tightly docile will not be moved at the conical top of inner bag 201；
C, so, when hydraulic cylinder 307 is descending, the height 1200mm- for the fibre fabric block 500 that can rebound mobile
200mm=1000mm, about 320Kg-80Kg=240Kg；
D, when hydraulic cylinder 307 is descending, it is fastest, be released maximum fibre fabric block 500 should be exactly to lean on
The part fibre fabric block 500 of nearly active sieve plate, the fibre fabric block 500 of other parts will see the fibre fabric block 500 of lower floor
Action, lowermost fibre cloth 500 moves, and they just have an opportunity to move, due to naturally lower being moved by the bounce of fibre fabric block 500
(very regular dynamic).When balanceExactly the internal descending deformation extent with fibre fabric block 500 offsets.
E, the averag density in the body of fibre fabric block 500 of the filtering of 1000mm height：240 ÷ 1=240kg
3rd step：See Figure 10 right figure
Rule according to above-mentioned loosening is calculated
A, height：1000mm, density：240kg/m3
B, the density of part fibre fabric block 500 close to active sieve plate：240kg/m3÷ 2=120kg/m3
C, the density from this few fibers cloth 500 at the top 200mm of conical inner bag 201：240 kg/m3+
120kg/m3=360kg/m3。
Material is thus formed density gradient.There is density gradient, filter gradient could be realized, this is the spy of in-depth filtration
Point.
In-depth filtration is the process filtered using filter medium internal clearance, and suspended particulate is less than the hole of filter medium
Gap, thus particle can enter people it is longer and bend hole and be trapped, this process is characterized in that filtration was resulted from
Filter medium layer is internal, while each hole has the possibility of the trapped particles from the suspension for flowing through it.
