The gap of suction tube 3 is constructed closed with watertight.And then, the suction that the annular packing 5 will be open between adjacent hollow filter piece 1
The suction hole 4 of skirt 3 is inaccessible with watertight state.
Each hollow filter piece 1 is laminated in the pushing surface of annular packing 5 on two sides in the opening edge of through hole 2,
And it is closed by being constructed with watertight.In this condition, hollow filter piece 1 as shown in Figure 13 and Figure 14, filter by the two panels of hollow filter piece 1
Material 11 is pressed against on the surface of pad 12 by annular packing 5, and filter material 11 is deformed into the shape on the surface along pad 12, in filter material
Set narrow by gap 7 between 11 and pad 12.That is, the filter material 11 of hollow filter piece 1 is pushed away from two sides by annular packing 5
Pressure, makes filter material 11 be deformed into the shape on the surface along pad 12, forms narrow by gap 7 between filter material 11 and pad 12.
This it is narrow by gap 7 be make liquid by but limitation as the suspension solid content in liquid filtrate D the gap for passing through,
Drainage gap 8 than being formed between the filter material 11 and pad 12 not clamped by annular packing 5 is small.Here, Figure 13 and Figure 14
Represent it is narrow limited as the passing through of the filtrate D of the suspension solid content in liquid by gap 7, to be deposited in it narrow by gap
The state in 7 outside.

The clamping part 1X of ring-type is urged into, forms narrow by gap 7 between filter material 11 and pad 12.Annular packing 5 pushes filter material
The pushing force on 11 surface determines the narrow size by gap 7 being formed between filter material 11 and pad 12.If filling out ring-type
The pushing force that material 5 pushes the surfaces of filter materials 11 becomes strong, then make to be formed between filter material 11 and pad 12 narrow is become by gap 7
It is narrow, can effectively limit passing through as the filtrate D of solid content.If conversely, making annular packing 5 push the table of filter material 11
The pushing force in face dies down, then can make to be formed between filter material 11 and pad 12 narrow become big and make efficient liquid by gap 7
Rate ground is passed through.Thus, adjustment annular packing 5 pushes the pushing force on the surface of filter material 11, so as to be formed in filter material 11 with pad 12
Though between it is narrow by gap 7 turn into making efficient liquid rate by can effectively limit as the suspension in liquid
The size for passing through of the filtrate D of solid content.Such as adjustment annular packing 5 pushes the pushing force on the surface of filter material 11, so that right
The pushing force of the unit length of circumferencial direction turns into 1kgf/cm~6kgf/cm.Here, the circumferencial direction of so-called annular packing
Length, is the length of the circumferencial direction calculated using the internal diameter of the filler of ring-type and the average value of external diameter.
Hollow filter piece 1 above as shown in Figure 13 and Figure 14, in the state of being clamped with annular packing 5 from two sides, is filtered
Material 11 forms smaller than drainage gap 8 narrow by gap 7 along the areal deformation of pad 12.Additionally, hollow filter piece 1 is in ring
The lower deformation of pushing force effect of shape filler 5, so that pad 12 itself is crushed, the concavo-convex of surface diminishes, and is formed than drainage gap 8
Small is narrow by gap 7.So, what is formed in the clamping part 1X pushed by annular packing 5 is narrow by such as Figure 13 of gap 7 to figure
Shown in 15, pass through the liquid component being drawn into suction tube 3 from the hollow bulb 10 of hollow filter piece 1, but limitation is used as liquid
