Specific embodiment
It please refers to shown in Fig. 1 to Fig. 3, it to be a kind of that show the specific structures of the preferred embodiment of the utility model
Binary channels multistage slurries filtration system, structure include a dispersal device 10, Multistage filtering device, multistage except magnetisable material filters
Device, a collection device 40.Wherein, Multistage filtering device is multiple formation of filter device 20 of being connected by pipeline 50.Multistage is removed
Magnetisable material filter device be connected by pipeline 50 it is multiple except magnetisable material filter devices 30 formation.Connection between each device
Relationship is as follows: for the slurry outlet of the dispersal device 10 by the several groups Multistage filtering device in parallel of pipeline 50, several groups are multistage
After the slurry outlet of filter device converges, magnetisable material filter device is removed again by the several groups multistage in parallel of pipeline 50, this is more
Grade is output to collection device 40 except the end of magnetisable material filter device.Such slurries filtration system, can multistage filtering, filtering effect
Fruit is good, can gradient filtration;Multistage can remove magnetic, except magnetic effect is good, can gradient remove magnetic;Filtering function and except magnetisable material function it is clear
It is clear, facilitate judgement where to go out abnormal.
As shown in Figure 1, the filter device 20 is by thtee-stage shiplock, two groups in parallel, forms binary channels three-stage filtration.Institute
It states except magnetisable material filter device 30 is by thtee-stage shiplock, two groups in parallel, and shape energy binary channels three-level removes magnetic.This binary channels is set
Meter, meets continuous production.However, it is necessary to explanation, the filter device for the more stages that can also connect according to demand when design
20/ removes magnetisable material filter device 30, and the filter device 20/ of more multiple groups in parallel removes magnetisable material filter device 30, can
Meet efficiently and reach and more preferably filters/remove magnetic effect.
As shown in Fig. 2, being docked between each device and pipeline 50 by clip 51,51 docking mode of clip makes dismounting more
It is easy, once device damages more accordingly or needs clean etc., removes the present apparatus after can quickly unscrewing clip 51, it is convenient
Operation and use.And it is equipped with control valve 52 on the pipeline 50 of each section docking, queueing problem is examined when facilitating system exception
It repairs, replace, clean.
As shown in Figures 3 to 5, the structure of the filter device 20 includes outer sleeve 21 and filter core 22, the filter core 22 insertion
To outer sleeve 21, one end of outer sleeve 21 is first entrance 23, and the other end of filter core 22 is first outlet 24.After slurry dispersion
Enter inside outer sleeve 21 from first entrance 23, after entering back into filter core 22, is exported from first outlet 24.It gathers on the filter core 22
There are multiple filter openings 25, by the impurities in slurry in the space 26 between filter core 22 and outer sleeve 21, to play filtering
Effect.In the present embodiment, the mesh number of 22 strainer of filter core is 80~150 mesh any combination.Such as it can be in by-pass filtration
80 strainers are selected, 120 mesh filter screens are selected in secondary filtration, 150 mesh filter screens are first used in three-stage filtration, in this way, realizing multistage
Filtering, can gradient filtration, effect is good.
It is as shown in Figure 6 and Figure 7, described except magnetisable material filter device 30 includes outer barrel 31 and magnet absorption filter element 32,

Cylinder 31 assembles.The design of handle 321 facilitates entire magnet absorption filter element 32 to extract out from outer barrel 31, again, it is preferred in cover board
Waterproof grommet is set between 322 and outer barrel 31.
As shown in fig. 7, magnetosheath 35 can be set in 32 housing of magnet absorption filter element, magnetosheath 35 does not have magnetism, and
Magnetosheath 35 is very thin, and the magnetic field of magnet absorption filter element 32 can penetrate magnetosheath 35, and the substance (such as iron) that can be adsorbed is sticked to magnetic
Cover 35 surfaces.After magnet absorption filter element 32 and 35 entirety of magnetosheath are extracted out from outer barrel 31, as long as unloading magnetosheath 35, it is sticked to magnetic
The substance for covering 35 surfaces voluntarily falls off, easy to clean, easy to use.This scheme makes Permanentmagnet bar 323 not need directly to contact can be by
The substance of absorption, easy to clean, putty, does not take material.It is, of course, also possible to as shown in figure 8, magnetosheath 35 is not provided with, directly by magnet
Absorption filter element 32 is inserted into outer barrel 31 also can normal use.
The filtering process of the binary channels multistage slurries filtration system of the utility model is:
In Production Process of Lithium Battery, slurry is dispersed by dispersal device 10, subsequently into wherein the one of Multistage filtering device
In channel, N grades of filterings are waited by level-one, second level, three-level ..., big pellet object is isolated;It enters back into multistage except magnetic material
In a wherein channel for matter filter device, N grades of magnetic absorptions are waited by level-one, second level, three-level ..., by the magnetic in slurry
Property substance adsorbs, so that magnetisable material be effectively prevent to enter subsequent processing.Any bar is filtered when filtering and removing magnetisable material
For the pause of the needs such as path deterioration, maintenance, replacement, cleaning in use, other alternate channel can be opened, realization is free of discontinuities continuous
Metaplasia produces.All slurries by filtering and removing magnetisable material are stored in collection device 40, in case entering in subsequent processing makes
With.
