Detailed description of the invention
First the method for mounting an elongate sealing strip 10 in a circumferential groove 11 in a lower surface of a filter plate 3 of a vertical pressure filter 1 and some embodiments and variants of the method will be described in greater detail.
The method comprises providing an elongate sealing strip 10 having opposite end portions (not marked with a reference numeral) and an end surface 12 at each end of the elongate sealing strip 10.
The method comprises by placing the elongate sealing strip 10 in the circumferential groove 11 so that the opposite end portions of the elongate sealing strip 10 overlap and so that the end portions of the elongate sealing strip 10 form a lower end portion 13 and an upper end portion 14.
The method comprises providing a cutter 15.
The method comprises cutting the upper end portion 14 of the elongate sealing strip 10 with the cutter 15 so that so that the end portions of the elongate sealing strip 10 form a shortened overlapping section 16.
The method comprises forcing the opposite end portions into the circumferential groove 11 so that the end surfaces 12 of the opposite end portions of the elongate sealing strip 10 abut.
An advantage of the method is that because only one sealing strip is used, only one joint is formed in the seal. Another advantage is good sealing effect at the joint between the opposite end surfaces 12 due to the pressure between the end surfaces 12.
In the method, the cutting of the upper elongate sealing strip 10 portion with the cutter 15 is preferably, but not necessarily, done so that an overlapping length of the shortened overlapping 16 section is between 1 and 25 mm, preferably between 1 and 10 mm.
The method comprises preferably, but not necessarily, providing a cutter guide 17 comprising an abutment surface 18 configured for co-operation with one of the end surfaces 12 of the elongate sealing strip 10, a guide groove 19 configured for guiding the cutter 15 during cutting the elongate sealing strip 10, and at least one supporting surface 20 configured to support the elongate sealing strip 10 during cutting the elongate sealing with the cutter 15, placing the abutment surface 18 of the cutter guide 17 in contact with the end surface 12 of the lower end portion 13 of the elongate sealing strip 10, and supporting the upper end portion 14 of the elongate sealing strip 10 at said at least one supporting strip of the cutter guide 17 during said cutting the upper end portion 14 of the elongate sealing strip 10 with the cutter 15 so that so that the end portions of the elongate sealing strip 10 form a shortened overlapping section 16. An advantage of providing and using a cutter guide 17 is that it is easier to cut the elongate sealing strip 10 so that a proper end surface 12 and shortened overlapping section 16 results.
If the method comprises providing a cutter guide 17, the abutment surface 18 and a cutting plane 21 of the cutter 15, when the cutter 15 is guided by the guide groove 19, is preferably, but not necessarily, essentially parallel and distanced from each other.
An advantage of this is that the end surfaces 12 will be perpendicular to the longitudinal direction of the elongate sealing strip 10, which means that the forcing of the opposite end portions into the circumferential so that the end surfaces 12 of the opposite end portions of the elongate sealing strip 10 abut is easy.
If the method comprises providing a cutter guide 17, the abutment surface 18 and a cutting plane 21 of the cutter 15, when the cutter 15 is guided by the guide groove 19, is preferably, but not necessarily, essentially parallel and the cutting plane 21 of the cutter 15 being at a distance from the abutment surface 18 in the direction towards the end surface 12 of the upper end portion 14.
An advantage of this is that the end surfaces 12 will be perpendicular to the longitudinal direction of the elongate sealing strip 10, which means that the forcing of the opposite end portions into the circumferential so that the end surfaces 12 of the opposite end portions of the elongate sealing strip 10 abut is easy If the method comprises providing a cutter guide 17, the abutment surface 18 and a cutting plane 21 of the cutter 15, when the cutter 15 is guided by the guide groove 19, is preferably, but not necessarily, in an angle with respect to each other and distanced from each other.
An advantage of this is better sealing effect in a transversal direction of the elongate sealing strip 10, because the joint between the end surfaces 12 of the elongate sealing strip 10 will not extend transversely through the elongate sealing strip 10.
The method comprises preferably, but not necessarily, cutting the upper end portion 14 of the elongate sealing strip 10 with the cutter 15 so that the end surface 12 of the upper end portion 14 of the elongate sealing strip 10 is essentially perpendicular with respect to a longitudinal direction of the elongate sealing strip 10.
