Specific implementation mode
Following example is structure in order to further illustrate the present invention, but be should not be limited thereto.
Shown in Fig. 3 to Fig. 8, the present invention provides a kind of isolated location 4 and includes the rotational pressure of the isolated location 4
Filter, the isolated location 4 are made of fixed seat 1, spacing block 2 and fastener 3, and the inside of fixed seat 1 is interior with spacing block 2
Side is linked into an integrated entity by multiple fasteners 3；The outer surface of fixed seat 1 is equipped with loss of weight empty slot, to mitigate the matter of fixed seat 1
Amount.
Shown in Fig. 1 to Fig. 2, isolated location 4 is set to the inside of the frame 6 of rotary pressure filter, spacing block 2
The sealant 7 that outside is formed is bonded with the outer surface of rotary drum 5.Rotary pressure filter is by being arranged the isolation list in 6 inside of frame
Member 4 is divided into multiple independent functional areas.
When rotary pressure filter works, under the action of external pressure, sealant 7 is fitted tightly over rotational pressure mistake
Rotary pressure filter is divided into multiple independent functional areas by the outer surface of the rotary drum 5 of filter, rotary drum 5 inside frame 6 to
The heart rotates, and isolated location 4 and frame 6 are stationary, and material rotates together with rotary drum 5, are completed not in different function region
Same process.
Rotary pressure filter in above-mentioned operational process, when causing filter-press to feed due to material characteristic exist compared with
Big pressure oscillation, using sealant in the prior art shown in Fig. 9 structure when, when rotary drum cell 8 by discharge zone enter into
When expecting area, due to the unexpected appearance of 8 cavity of rotary drum cell, lead to feed zone rapid decompression, causing feed zone, there are larger
Pressure oscillation influences the long-period stable operation of equipment.
In view of the above-mentioned problems, isolated location 4 provided by the invention can reduce pressure oscillation larger existing for feed zone.
Shown in Figure 10-Figure 16, empty slot is offered on the outer surface of the sealant 7 in spacing block 2, empty slot is along sealant 7 close to rotation
The long side side for turning the feed zone of filter-press is cut and is formed, and the width of the empty slot increases from one end to the other end
Or first increases and then decreases.The mode of the increase/reduction preferably includes linear, curved shape, stairstepping or two or more above-mentioned
The combination of mode.
Shown in Fig. 4 and Fig. 5, the long length of side and the short side length of the sealant are respectively its length and width, the sky
The length and width of slot is consistent with the length and width direction of the sealant respectively.The cross-sectional area of the empty slot accounts for sealing
The 50% or 40% of the cross-sectional area of layer 7 is hereinafter, to ensure the leakproofness of isolated location sealing surface.Also, the empty slot
Width and length are preferably respectively smaller than the width and length of the sealant；The both ends of the empty slot not with the sealant
Either end in both ends overlaps.
Specifically, the empty slot can be continuous, and width increases from one end to the other end.One of which embodiment party
Formula, shown in Figure 10, linear increases the width of the empty slot from one end to the other end, and cross section is triangle.Wherein
Another embodiment, shown in Figure 15, stairstepping increases the width of the empty slot from one end to the other end, and cross section is
Stairstepping.Above structure can make rotary drum cell 8 step into feed zone so that enter the rotary drum cell 8 of feed zone
The variation of volume is substantially reduced, and to make material gradually fill rotary drum cell 8, and then the pressure oscillation of feed zone is made to drop significantly
It is low；Wherein another embodiment, shown in Figure 16, the cross section of the empty slot is on the basis of triangle, inside it
The trapezoidal part sealant in 3 unhewn cross sections is remained with, which can make material first pass through vee gutter gradually
Into feed zone rotary drum cell 8, rotary drum cell 8 is carried out pre-filled, and then pressure oscillation is made to substantially reduce；Meanwhile it protecting
The unhewn part sealant stayed makes sealant 7 and the contact area of rotary drum 5 increase, and the stress of isolated location 4 is more preferable, by force
Degree is more preferable.It is symmetrical variation (that is, the empty slot can be continuous and width is from one end to another with above-mentioned empty slot change width
End reduce) situation repeat no more.
Specifically, the empty slot can be continuous, and width first increases and then decreases from one end to the other end.One of which
Embodiment, shown in Figure 14, the width of the empty slot subtracts after first increase maintains one section of this width again from one end to the other end
It is small, it is repeated twice after first increasing one section of this width of maintenance and reduces again again afterwards, cross section is on the basis of triangle, in its bevel edge
On be connected with 3 it is trapezoidal.The structure can make material step into feed zone rotary drum cell 8 by dovetail groove first, to turning
Drum unit lattice 8 carry out pre-filled, then chamfer slot by bottom and gradually fill up rotary drum cell 8 successively, and then keep pressure oscillation big
It is big to reduce；Wherein another embodiment, shown in Figure 13, the width of the empty slot first increases from one end to the other end to be subtracted afterwards
Small, cross section is isosceles triangle.The structure can make material step into feed zone from gable top, into feed zone
The volume of rotary drum cell 8 can be substantially reduced, and then pressure oscillation is made to substantially reduce.
Specifically, empty slot can also be intermittent, and width increases from one end to the other end.One of which embodiment,
Shown in Figure 12, the cross section of empty slot is triangle, wherein there are three the unhewn sealant of trapezoidal reservation by its
It blocks.The structure can make rotary drum cell 8 step into feed zone so that 8 volume of rotary drum cell for entering feed zone is big
It is big to reduce, to make material gradually fill rotary drum cell 8, and then the pressure oscillation of feed zone is made to substantially reduce；Simultaneously because
Above structure is intermittent-cutting so that sealant 7 and the contact area of rotary drum 5 increase, and the stress of isolated location 4 is more preferable, intensity
More preferably.With above-mentioned empty slot change width be symmetrical variation (that is, the empty slot can be continuous and width from one end to the other end
First reduce and increase afterwards) situation repeat no more.
Certainly, the structure of empty slot is also based on structure shown in above-mentioned Figure 10 to Figure 16 and is combined and deforms, with
Realization makes material step into feed zone, and then the purpose for making pressure oscillation substantially reduce.
Certainly, the present invention can also have other various embodiments, without deviating from the spirit and substance of the present invention, ripe
Various corresponding change and deformations, but these corresponding change and deformations can be made according to the present invention by knowing those skilled in the art
It should all belong to the scope of protection of the present invention.
