Clearly illustrate technical solution of the present invention, therefore be only used as example, and cannot be used as a limitation and limit protection model of the invention
It encloses.
Fig. 1 to Fig. 8 is please referred to, in the present embodiment, two adjacent compressible oil cylinder sheet frame filter plates of a super-pressure
The contact of the expansion plate 2315 of substrate 2313 and the compressible oil cylinder sheet frame filter plate of another super-pressure forms filter chamber.Super-pressure is compressible
Oil cylinder sheet frame filter plate includes substrate 2313, mounting plate 2314, expansion plate 2315, plate 2311 of leaking water, leak water plate 23110, filter cloth
2316 and 2317 substrate 2313 of feeding cylinder, mounting plate 2314,2315 three of expansion plate be successively arranged side by side.Substrate 2313 and flexible
Plate 2315 is annular shape.2314 two sides of mounting plate are disposed with from inside to outside is provided with leak water plate 2311 and plate of leaking water
23110.The two sides of mounting plate 2314 offer several rhones 23142.The side wall of mounting plate 2314 offers discharge outlet
23141.Each rhone 23142 is connected to by discharge outlet 23141, and through to the outside of mounting plate 2314.
There are two filter clothes 2316, and two filter clothes 2316 are respectively overlay on the outer surface of substrate 2313 and expansion plate 2315.
That is a filter cloth 2316 is tightly attached to leaking water on plate 2311 in substrate 2313 and substrate 2313.Another filter cloth 2316 is tightly attached to
Leaking water on plate 2311 in expansion plate 2315 and expansion plate 2315.Reset structure is installed between expansion plate 2315 and substrate 2313
Part.Reset components can push expansion plate 2315 to slidably reciprocate.Feeding cylinder 2317 is axial to be located at the compressible oil cylinder sheet frame filter of super-pressure
The middle part of plate can penetrate through at substrate 2313 and expansion plate 2315 before and after two filter clothes 2316.
Fig. 4 is referred to, in the present embodiment, expansion plate 2315 and mounting plate 2314 are additionally provided with flexible sliding ring 2319.It stretches
Contracting slip ring 2319 cuts with the gradient close to filter chamber side.Expansion plate 2315 can be along 2319 outer of flexible sliding ring constantly to another
2313 direction of substrate of the compressible oil cylinder sheet frame filter plate of super-pressure is mobile.Flexible sliding ring 2319 has guiding role, while the gradient
Filter cloth 2316 can be prevented by the vertical backfin of filter cake, to be conducive to extend 2316 service life of filter cloth.
Referring to Figure 1, reset components are sheet frame oil cylinder 2312.In the present embodiment, it when expansion plate 2315 is pressurized, stretches
Contracting plate 2315 is compressed with sheet frame oil cylinder 2312, the hydraulic oil oil return in sheet frame oil cylinder 2312；After expansion plate 2315 is not pressurized, plate
Hydraulic oil oil inlet in frame oil cylinder 2312, sheet frame oil cylinder 2312 eject, and expansion plate 2315 living is ejected reset.Meanwhile flexible
Limit sliding pin 2318 and stop collar are also equipped between plate 2315 and substrate 2313.It limits sliding pin 2318 and stop collar is circumferentially uniform
Alternate is mounted between expansion plate 2315 and substrate 2313.Sheet frame oil cylinder 2312 is used as reset components, promotes expansion plate 2315
It resets.It is constant that such sheet frame oil cylinder 2312 does not allow vulnerable deformation, long service life, and stroke to stablize, and resets accurate.Limit is slided
Pin 2318 and stop collar can prevent sheet frame oil cylinder 2312 bad by crushing.
Fig. 4 is referred to, in the present embodiment, expansion plate 2315 is provided with the gradient, base at the inner ring of the side of filter chamber
Plate 2313 is provided with the gradient at the inner ring of the side of filter chamber.That is expansion plate 2315 and 2313 outside of substrate all concaves.Expand
Big filters pressing cavity, to improve filter efficiency.
Fig. 3 and Fig. 5 are referred to, in the present embodiment, 23110 tabletting of water-permeable membrane, water-permeable membrane are provided on feeding cylinder 2317
23110 are pressed on by 23110 tabletting of water-permeable membrane and leak water on plate 2311.Water-permeable membrane 23110 can prevent filter cloth 2316 to be tightly attached to away
On water plate 2311, the plate 2311 that will leak water is blocked.
The above-mentioned compressible oil cylinder sheet frame filter plates principle of super-pressure: please also refer to Fig. 9 and Figure 10, every two pieces adjacent
The substrate 2313 of the compressible oil cylinder sheet frame filter plate of super-pressure stretches with a kind of another compressible oil cylinder sheet frame filter plate of super-pressure
The contact of plate 2315 forms a filter chamber, and prevents material from revealing by 23131 linear sealing of O-ring.Material from feeding cylinder 2317 into
Enter and fills up filter chamber, under external force, expansion plate 2315 is constantly moved to 2313 direction of substrate along 2319 outer of flexible sliding ring,
Filter chamber volume constantly reduces.Water reaches 2311 two sides of plate of leaking water through filter cloth 2316, water-permeable membrane 23110, flows under the effect of gravity
It is discharged to the rhone 23142 of 2314 lower section of mounting plate, then from the discharge outlet 23141 between rhone 23142.Filtering is completed
Afterwards, the reset of sheet frame oil cylinder 2312 opens expansion plate 2315, substrate 2313, the separately rear cake discharge of expansion plate 2315 and substrate 2313
The head of oil cylinder 232 opens the filter cake for the type of being pressed into, and after filter cake is fallen under the effect of gravity, then can carry out next filter ring
Section.
