Detailed description of the invention
The present invention is described in further detail below in conjunction with the accompanying drawings, described in be explanation of the invention and
It not to limit.
As in figure 2 it is shown, device of the present invention include electric pushrod 1, push rod installing plate 2, central layer and
Valve body 6, central layer includes central layer main body 3, seal washer 4 and yoke 5；It is provided with in central layer main body 3
Yoke 5, acts primarily as the effect of conducting magnetic circuit, and seal washer 4 rises between central layer main body 3 and yoke 5
Sealing function.Central layer inserts in valve body 6, and push rod installing plate 2 is arranged on valve body 6, electric pushrod 1
It is slidably mounted on push rod installing plate 2, and electric pushrod 1 is fixed with central layer and is connected.Such as Fig. 3 and 4 institute
Showing, central layer main body 3 includes fixing magnetic system 9 and mobile magnetic system 10, and mobile magnetic system 10 is connected by spring 11
It is connected on fixing magnetic system 9 middle part.It is fixed on the fixing magnetic system 9 of central layer main body 3 one end by multiple parallel
And the magnetic group composition of spaced setting, including multiple permanent magnets in each magnetic group, permanent magnets is along magnetic pole side
To being sequentially arranged, the magnetic pole of adjacent permanent magnet block is contrary；Mobile magnetic system 10 is slidably arranged in central layer main body 3
The other end, the magnetic group structure of mobile magnetic system 10 is identical with the magnetic group structure of fixing magnetic system 9, movement magnetic
Be 10 magnetic group be embedded between the magnetic group of fixing magnetic system 9.Wherein, move arrange in magnetic system 10 limited
Position block 12；When valve body 6 is opened, spring 11 promotes mobile magnetic system 10 to left movement, limiting block
Just stagger the length of a permanent magnets in the position of position and fixing magnetic system 9 that block 12 limits mobile magnetic system 10
Degree；When valve body 6 is closed, mobile magnetic system 10, by the counteracting force of body base, makes mobile magnetic system
10 move, and the position that positive stop 12 limits mobile magnetic system 10 is the most right with the position of fixing magnetic system 9
Together.
In this preferred embodiment, as shown in Figure 3 and Figure 4, mobile magnetic system 10 includes two groups of magnetic groups, fixing
Magnetic system 9 includes that three groups of magnetic groups, two groups of magnetic groups of mobile magnetic system 10 are respectively embedded in the three of fixing magnetic system 9
In two intervals that group magnetic group is formed.Each magnetic group all includes five permanent magnets.
The method of the invention, it is vertical to be arranged at fiberizer stock inlet by mounting flange 7 by this device
Immediately below direction slurry pipeline 8, under fiberizer normal operating conditions, slurry is flowed to level by vertical pipeline
Pipeline also enters fiberizer stock inlet, and now, this device valve port is closed, now, and valve body 6
In central layer band be magnetic, when the irony foreign material in slurry can be flowed through this device by vertical pipeline, by
The magneticaction of the magnetic central layer in device, absorption yoke 5 surface on central layer, stop irony miscellaneous
Thing enters fiberizer.When equipment downtime maintaining, valve port can be promoted automatically will by electric pushrod 1
This device is opened, and now central layer does not the most have magnetic, it is impossible to continue to attract to be fixed on yoke by irony magazine
5 surfaces, the absorption irony foreign material on yoke 5 surface are automatically drained out.
The operation principle of the present invention is under device opening, as it is shown on figure 3, mobile magnetic system 10 is at bullet
Ejecting under the effect of spring 11, movement magnetic system 10 is limited to specify position by positive stop 12 so that shifting
Just staggering the length of a permanent magnets in the position of the position of dynamic magnetic system 10 and fixing magnetic system 9, makes mobile
Align with the S pole of fixing magnetic system 9 in the N pole of magnetic system 10, the S pole of mobile magnetic system 10 and fixing magnetic system 9
The alignment of N pole, according to the principle of continuity of magnetic flux and magnetic field superposition principle, magnetic pole cancellation, magnetic drops
Low, core plate surface, substantially without producing magnetic, does not produce magnetic in actual application.As shown in Figure 4.When
When device is closed, electric pushrod 1 promotes central layer to move, and mobile magnetic pole 10 touches the bottom of valve body 6
Time, under the thrust of electric pushrod 1, mobile magnetic system 10 gradually moves right, positive stop 12
It is limited to specify position by movement magnetic system 10, makes the position of mobile magnetic system 10 and the position of fixing magnetic system 9
Alignment, it may be assumed that align in just N pole with fixing magnetic system 9, the N pole of mobile magnetic system 10, mobile magnetic system 10
S pole align with the S pole of fixing magnetic system 9, according to the principle of continuity of magnetic flux and magnetic field superposition principle, this
Time magnetic field superposition, the magnetic line of force from magnet N pole out, through yoke 5, returns to magnet S pole, yoke
Surface produces magnetic such that it is able to by irony impurity absorption in yoke surfaces.
