Abstract
Disclosed is a mounting error self-adaptation sealing device. The mounting error self-adaptation sealing device comprises packing, a water string ring, a packing box, a packing gland and a folio support, wherein the outer surface of the support is fixedly connected with a groove body of a pulp storage groove, the inner surface of the support is an inward-recessed spherical face, the packing box is mounted on a spindle, the outer surface of the packing box is a convex spherical face and is matched with the inner surface of the support, the packing box is fixed through the folio support, a sealing ring is mounted on the outer circle of the packing box, a filling cavity is formed between the packing box and the spindle, the packing and the water string ring are mounted in the filling cavity, and the packing gland tightly presses the packing and seals the opening end of the packing box through a fastener. Due to the fact that the inner surface of the support and the outer surface of the packing box are in spherical face fit, mounting errors can be compensated, even though perpendicularity has errors, the center line of the spindle can still be kept level and straight all the time, so that the mounting error self-adaptation function is achieved, operation is stable and reliable, the mounting accuracy requirement of different devices can be completely met, stable operation of the devices is guaranteed, and the clamping phenomenon is avoided.
Description
Technical field
The utility model relates to a kind of seal arrangement of self adaption alignment error, belongs to papermaking equipment field, is mainly used in storing the installation sealing between stock tank and main shaft.
Background technique
In each equipment of paper industry, seal arrangement plays vital effect.Packing seal is because of cheap, simple in structure, and is widely used.Modal is exactly to adopt packing_seal.And packing_seal is very high to precision of equipment installation requirement, if there is larger error, can cause equipment operation not steady, spindle abrasion is serious, finally occurs leakage phenomenon, thereby loses the effect of sealing.Such as, storage stock tank in paper industry now, diameter reaches 4500-9000mm, height 12000-22000mm, volume reaches 500-2000m3, and the stirrer of its outfit is the stirring apparatus that is installed on cell body bottom level, if by rarely having seal arrangement to seal cell body and main shaft, the center line of the main shaft of stirrer must keep vertical with storage stock tank, but for storage stock tank, the construction on its concrete basis and installation process, want to reach quite high installation precision often more difficult, and storage stock tank also has error in manufacture process, therefore seal process is installed wastes time and energy, sometimes also have to reinstall.Hence one can see that, and existing stuffing seal can not adapt to this requirement.
Model utility content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: provide a kind of structural design simple, produce seal arrangement easy for installation, self adaption alignment error that stable operation is reliable, installation precision with low cost, that can fully meet distinct device requires.
The seal arrangement of self adaption alignment error described in the utility model, comprise packing, string water ring, Stuffing box, Gland and the bearing of splitting, the outer surface of bearing is fixedly connected with the cell body of storage stock tank, internal surface is indent spherical, Stuffing box is arranged on main shaft, the outer surface of Stuffing box is evagination spherical, match with the internal surface of bearing, the bearing of splitting is fixed Stuffing box, on Stuffing box cylindrical, seal ring is installed, between Stuffing box and main shaft, there is cavity filling, packing and string water ring are installed in cavity filling, Gland compresses packing and seals the opening end of Stuffing box by fastening piece.
When use, first Stuffing box is arranged on main shaft, packing, string water ring are then installed in the cavity filling between Stuffing box and main shaft, then (Gland had both compressed packing to fix Gland at the opening end of Stuffing box by fastening piece (as bolt), seal again the opening end of Stuffing box), afterwards bearing is arranged on the cell body of storage stock tank, and by the bearing of splitting, Stuffing box is fixed, finally accomplish fluently table and determine after perpendicularity, fit sealing device.
Due in this seal arrangement, the internal surface of bearing adopts spherical to coordinate with the outer surface of Stuffing box, therefore can compensate alignment error, even if there is error in perpendicularity, it is straight that the center line of main shaft also can remain, thereby can self adaption alignment error, the equipment of assurance operates steadily, without jam phenomenon.Seal ring on Stuffing box cylindrical, guarantees without any Seepage, thereby has guaranteed its sealing.
The beneficial effect that the utility model compared with prior art had is:
The seal arrangement of this self adaption alignment error, structural design is simple, with low cost, it is easy for installation to produce, coordinate because the internal surface of bearing and the outer surface of Stuffing box adopt spherical, therefore can compensate alignment error, even if perpendicularity exists error, it is straight that the center line of main shaft also can remain, thereby can self adaption alignment error, stable operation is reliable, and can fully meet the installation precision requirement of distinct device, the equipment of assurance operates steadily, without jam phenomenon; Seal ring on Stuffing box cylindrical, guarantees without any Seepage, thereby has guaranteed its sealing.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 installs the structural representation of the present utility model that has error.
In figure: 1, bearing; 2, seal ring; 3, Stuffing box; 4, main shaft; 5, packing; 6, string water ring; 7, the cell body of storage stock tank; 8, Gland.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further:
As shown in Figure 1, the seal arrangement of this self adaption alignment error comprises packing 5, string water ring 6, Stuffing box 3, Gland 8 and the bearing 1 of splitting, the outer surface of bearing 1 is fixedly connected with the cell body 7 of storage stock tank, internal surface is indent spherical, Stuffing box 3 is arranged on main shaft 4, the outer surface of Stuffing box 3 is evagination spherical, match with the internal surface of bearing 1, the bearing 1 of splitting is by fixing Stuffing box 3, on Stuffing box 3 cylindricals, seal ring 2 is installed, between Stuffing box 3 and main shaft 4, there is cavity filling, packing 5 and string water ring 6 are installed in cavity filling, Gland 8 compresses packing 5 and seals the opening end of Stuffing box 3 by fastening piece.
When use, first Stuffing box 3 is arranged on main shaft 4, packing 5, string water ring 6 are then installed in the cavity filling between Stuffing box 3 and main shaft 4, then both compressed packing 5 at the opening end of Stuffing box 3 by the fixing Gland 8(Gland 8 of fastening piece (as bolt), seal again the opening end of Stuffing box 3), afterwards bearing 1 is arranged on the cell body 7 of storage stock tank, and by the bearing 1 of splitting, Stuffing box 3 is fixed, finally accomplish fluently table and determine after perpendicularity, fit sealing device.
In order to embody the excellent results of this seal arrangement, two kinds of installation forms are provided, it is the installation form that has error shown in the desirable installation form shown in Fig. 1 and Fig. 2, as can be seen from Figure 2, there is when mounted error in storage stock tank, center line the out of plumb of storage stock tank and main shaft 4, but due in this seal arrangement, the internal surface of bearing 1 adopts spherical to coordinate with the outer surface of Stuffing box 3, therefore can compensate alignment error, even if there is error in perpendicularity, it is straight that the center line of main shaft 4 also can remain, thereby can self adaption alignment error, the equipment of assurance operates steadily, without jam phenomenon.Seal ring 2 on Stuffing box 3 cylindricals, guarantees without any Seepage, thereby has guaranteed its sealing.
This seal arrangement is mainly realized its self adaption alignment error by its spherical cooperating structure as can be seen from above, novel structure, and feasibility is high, is specially adapted to stock trough agitator etc. and need to uses gland sealed equipment, applied range.
