Specific embodiment
Following example is the structure in order to further illustrate the utility model, but be should not be limited thereto.
Referring to shown in Fig. 3 to Fig. 8, the utility model provides a kind of isolated location 4 and includes the rotation of the isolated location 4
Filter-press, the isolated location 4 are made of fixed seat 1, spacing block 2 and fastener 3, inside and the spacing block 2 of fixed seat 1
Inside 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 fixed seat 1
Quality.
Referring to 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 on the isolation list of the inside of frame 6
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 exist in above-mentioned operational process, when causing the filter-press to feed due to material characteristic 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 utility model can reduce pressure larger existing for feed zone
Fluctuation.Referring to 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 leaned on along sealant 7
The long side side of the feed zone of nearly rotary pressure filter is cut and is formed, and the width of the empty slot is from one end to the other end
Increase or first increases and then decreases.The mode of the increase/reduction preferably includes linear, shaped form, stairstepping or two or more
The combination of aforesaid way.
Referring to shown in Fig. 4 and Fig. 5, the long length of side and short side of the sealant grow 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
