Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, the present invention is described further:
nullAs Figure 1-4，A kind of eccentric rotary film filter for the present invention，Including set casing 2、It is installed in rotation on the rotary sleeve 9 at set casing 2 top、For the motor 1 driving rotary sleeve 9 to work、It is positioned at the filter cylinder 12 of the cavity of set casing 2，Described filter cylinder 12 is upper end open and the structure in hollow form，Multiple filter opening 13 it is formed with on the circumferential side wall of described filter cylinder 12，The membrane 14 that on the outer circle wall of described filter cylinder 12, fixed cover matches with filter cylinder 12 outline equipped with outline，The inlet 4 towards filter cylinder 12 opening part it is provided with on the top of described set casing 2，The bottom of described set casing 2 is provided with drain pipe 7，Both sides bottom described rotary sleeve 9 have downwardly extended two connecting rods 10，Described filter cylinder 12 is hinged in these two connecting rods 10，The barycenter of described filter cylinder 12 deviates with the centrage of rotary sleeve 9.
nullThe solidliquid mixture to be filtered of the present invention flows in filter cylinder 12 at inlet 4，Then motor 1 is started，The rotation of set 9 is rotated，Then the synchronous rotary of filter cylinder 12 is driven，Can flow out at drain pipe 7 from penetrating liquid in the past in membrane 14，Solid particle in the past can not be penetrated from membrane 14 be then trapped within filter cylinder 12，Owing to filter cylinder 12 is hinged in the connecting rod 10 of rotary sleeve 9，Therefore，Filter cylinder 12 with rotary sleeve 9 synchronous rotary while，Also can rotate along the axis direction being perpendicular to rotary sleeve 9，And the setting that the centrage of the barycenter of filter cylinder 12 and rotary sleeve 9 deviates，Make filter cylinder 12 under an equal amount of rotating speed，The centrifugal force that liquid in filter cylinder 12 is subject to is bigger，Thus effectively prevent the colloidal particle in liquid and solute transportation from producing absorption in film surface or fenestra、The phenomenon that deposition causes membrane aperture to diminish or blocks，So that the present invention can preferably solve concentration polarization and the fouling membrane phenomenon of face，Significantly improve membrane permeation flux，Significantly improve the separating property of film.
When practical operation, can insert plastic bend tube at inlet 4, the bottom of bend pipe is connected with the opening of filter cylinder 12, until solidliquid mixture be passed through to filter cylinder 12 a certain amount of after, then this bend pipe is extracted out, then Guan Bi inlet 4.
As shown in Figure 2, the first embodiment deviated for the barycenter of filter cylinder 12 of the present invention and the centrage of rotary sleeve 9, being fixedly installed fixed block 15 on described filter cylinder 12, described fixed block 15 cooperatively forms interference with connecting rod 10, makes the barycenter of filter cylinder 12 deviate the centrage of described rotary sleeve 9.Under the cooperation of fixed block 15 and connecting rod 10, the barycenter more conveniently achieving filter cylinder 12 deviates the centrage of described rotary sleeve 9, so that filter cylinder 12 is under an equal amount of rotating speed, the centrifugal force that the liquid in filter cylinder 12 is subject to is bigger.
Preferably, the centrage of described filter cylinder 12 deviates with the centrage of rotary sleeve 9, can be by being deviated by the centrage of the centrage of filter cylinder 12 with rotary sleeve 9, the purpose that the centrage of barycenter Yu rotary sleeve 9 to reach filter cylinder 12 deviates.It can have employing two ways to realize this purpose:
As shown in Figure 3, the second embodiment deviated for the barycenter of filter cylinder 12 of the present invention and the centrage of rotary sleeve 9, the line of two pin joints 11 of described two connecting rods 10 and filter cylinder 12 intersects with the downward extended line of the centrage of rotary sleeve 9, and the line of these two pin joints 11 is non-intersect with the centrage of filter cylinder 12.
As shown in Figure 4, the 3rd embodiment deviated for the barycenter of filter cylinder 12 of the present invention and the centrage of rotary sleeve 9, the line of two pin joints 11 of described two connecting rods 10 and filter cylinder 12 is non-intersect with the downward extended line of the centrage of rotary sleeve 9, and the line of these two pin joints 11 intersects with the centrage of filter cylinder 12.
Preferably, described drain pipe 7 being provided with backwash water inlet pipe 8, the bottom of described set casing 2 is also equipped with backwash outlet pipe 6.Under the reversion of motor 1, can reality backwash design, the liquid after backwash flows out in backwash outlet pipe 6.
Preferably, the top of described set casing 2 is provided with compressed air inlet 3, and the top of described set casing 2 is additionally provided with drain 5.After compressed air is passed through at compressed air inlet 3, the liquid in filter cylinder 12 can be made to be easier to be penetrated into membrane 14 in membrane 14, accelerate the rate of filtration, after filtering, by opening drain 5, the compressed air in set casing 2 can be emptied.
Preferably, described set casing 2 includes shell main body 22, is arranged on the upper casing 21 at shell main body 22 top by bolt, by being fixed on the lower casing 23 bottom shell main body 22 by the way of welding.
In practice, shell main body 22 can be supported installing by bracing frame (not shown), and motor 1 can also be arranged on bracing frame.
Preferably, the inwall of described set casing 2 is provided with vibrator (not shown), by the vibration of this vibrator, the phenomenon that the colloidal particle in liquid and solute transportation produce absorption in film surface or fenestra, deposition causes membrane aperture to diminish or blocks can be prevented further.
The workflow of the present invention is: solidliquid mixture to be filtered flows in filter cylinder 12 at inlet 4, then motor 1 is started, the rotation of set 9 is rotated, then the synchronous rotary of filter cylinder 12 is driven, flow out at drain pipe 7 from penetrating liquid in the past in membrane 14, it is impossible to from membrane 14, penetrate solid particle be in the past then trapped within filter cylinder 12.Owing to filter cylinder 12 is hinged in the connecting rod 10 of rotary sleeve 9, therefore, filter cylinder 12 with rotary sleeve 9 synchronous rotary while, also can rotate along the axis direction being perpendicular to rotary sleeve 9, and the setting that the centrage of the barycenter of filter cylinder 12 and rotary sleeve 9 deviates, making filter cylinder 12 under an equal amount of rotating speed, the centrifugal force that the liquid in filter cylinder 12 is subject to is bigger.Filter cylinder 12 after a long time use, can clean by backwashing technology is counter.
For a person skilled in the art, can technical scheme as described above and design, make other various corresponding changes and deformation, and within all these changes and deformation all should belong to the protection domain of the claims in the present invention.
