Abstract
The utility model discloses a sealing strip for a filter plate of a press filter, which comprises a sealing strip body, wherein an arc groove is arranged at the bottom of the sealing strip body. The sealing strip has the advantages of good sealability, long service life and the like.
Description
Technical field
The utility model relates generally to the sealing strip on the chamber pressure filter board that is used for Separation of Solid and Liquid, relates in particular to the sealing strip on a kind of filter plate that is used for railway carriage or compartment type and sheet frame type filter press.
Background technology
Traditional filter plate periphery sealing means mainly is on the filter plate periphery, to paste or inlay rectangular seal bar or O type sealing strip; But the contact-making surface of filter plate and sealing strip is easily because of the extruding slag inclusion of sealing strip; Cause sealing property to descend; Filter pulp is leaked, and sealing strip damages by pressure easily too early, and service life is short.So a kind of cross sectional shape occurred is leg-of-mutton sealing strip, and has leg-of-mutton groove bottom the sealing strip, and sealing strip is embedded in the seal groove of the filter plate that matches.This sealing strip is because the bottom has triangular groove; Sealing strip pushes to the centre when pressurized, makes between sealing strip side and the filter plate slit to occur, clamps impurity easily; Can impel sealing strip further to the centre extruding again after clamping impurity, cause vicious circle.And leg-of-mutton groove stress distribution is inhomogeneous, after extruding repeatedly, causes the groove cracking easily, influences the sealing property and the service life of sealing strip.
The utility model content
The technical problem that the utility model will solve just is: to the problem that prior art exists, the utility model provides a kind of sealing property better, the sealing strip that is used for filter press filter board of longer service life.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of sealing strip that is used for filter press filter board comprises weatherstrip body, and the bottom of said weatherstrip body has the groove of circular arc.
Further improvement as the utility model:
The tangent line at circular arc end points place and the parallel sided of weatherstrip body on the said groove cross section.
The base width of said weatherstrip body triangular-section is 5mm～80mm, and top angle β is 5 °～170 °.
The outer surface at top, said weatherstrip body triangular-section is wedge angle or arc.
Compared with prior art; The advantage of the utility model is: in the utility model, the bottom of weatherstrip body offers circular groove, pushes to both sides during the weatherstrip body pressurized; Make weatherstrip body and filter plate paste tightlyer, effectively improved the sealing property of sealing strip; And the stress distribution of circular groove is more even, has avoided groove to ftracture because of being squeezed, and has prolonged the service life of sealing strip integral body.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Marginal data:
1, filter plate; 2, groove; 3, weatherstrip body.
The specific embodiment
Below will combine accompanying drawing and specific embodiment that the utility model is done further explain.
As shown in Figure 1, the utility model is used for the sealing strip of filter press filter board, comprises weatherstrip body 3, and the cross sectional shape of sealing bar body 3 is a triangle, and weatherstrip body 3 is embedded in the seal groove that matches on the filter plate 1.Cooperate the bottom that contacts to have the groove 2 of circular arc along the sealing strip length direction with filter plate 1 on the weatherstrip body 3.Because groove 2 is a circular arc, when weatherstrip body 3 pressurizeds, will push to both sides, make weatherstrip body 3 and filter plate 1 paste tightlyer, effectively improved the sealing property of weatherstrip body 3; And the stress distribution of circular groove 2 is more even, has avoided groove 2 to ftracture because of being squeezed, and has prolonged the service life of weatherstrip body 3.
In the present embodiment, as shown in Figure 1 from the cross section of weatherstrip body 3, OB is the side of weatherstrip body 3, and the tangent line at circular arc end points place (among the figure shown in the dotted line) is parallel with OB.The base width of weatherstrip body 3 is 5mm～80mm, and base angle is 10 °～80 °, and top angle β is 5 °～170 °.The outer surface of cupular part of weatherstrip body 3 is wedge angle or arc.
Below only be the preferred implementation of the utility model, the protection domain of the utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to the protection domain of the utility model.Should be pointed out that for those skilled in the art,, should be regarded as the protection domain of the utility model in the some improvement and the retouching that do not break away under the utility model principle prerequisite.
