DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The invention relates to a filter element, whereby the filter element is intended to be installed standing or hanging within a filter vessel, and whereby the filter element is formed by a filtration part and a supporting or mounting frame for the retaining of the filtration part, which frame has a substantially U-shaped section and is formed by a profile having a center part and two opposite border parts, between which border parts the filtration part can be enclosed.
BACKGROUND ART
When manufacturing an existing filter element the filtration part is slided between the border parts into the profile at a distance from the center part, after which the border parts are fastened onto the filtration part. This generally takes place by connecting the border parts together with the filtration part placed therein between by means of rivets. measurements of the filtration part, as well as during the mounting of the filtration part into the profile, it is possible that the two opposite border parts are displaced with respect to each other, which displacement of the border parts with respect to one another is continued along the entire periphery of the frame. With a finished element the aforesaid displacement is only partly prevented by the rivet connection, and the element may easily become deformed.
This is considered a drawback.
Also, the lack of torsional stiffness of the known filter element has a very negative influence on the maneuverability of the element.
The invention aims to obviate this drawback of the known filter element.
SUMMARY OF THE INVENTION
The filter element according to the invention overcomes the drawback by firmly fixing between and onto the two opposite border parts of the profile a strip of material.
According to a further characteristic of the filter element according to the invention, two or more strips of material are placed at a distance from one another in the longitudinal direction of the profile.
The strip or the strips may thereby be mounted in various ways.
According to a characteristic of the filter element according to the invention the strip or strips are placed extending parallel to the longitudinal direction of the profile.
According to a further characteristic the strip or strips are placed at a distance from the centre part.
Other features and characteristics of the filter element according to the invention will be explained with reference to the drawings of an embodiment by way of example.
BRIEF DESCRIPTION OF THE DRAWINGS
FIG. 1 is a front view of a filter element according to the invention.
FIG. 2 is a perspective view of a part of a profile according to the invention.
FIG. 3 is a cross section of the profile.
FIG. 4 is a part of a profile shaped into a bend.
FIG. 5a and 5b are cross sections respectively of a longitudinal section of another embodiment of the filter element according to the invention.
DETAILED DESCRIPTION OF THE INVENTION
As is shown in FIG. 1, the filter element is formed by a supporting or mounting frame 1, which is formed by a profile 2 having a substantially U-shaped section, with a center part 3 and, as shown in FIGS. 2 and 3, two oppositely disposed border parts 4. Between the border parts 4 the filtration part 5 is retained, which may consist of a heavy wire netting 6 over both sides of which a support gauze 7 is applied, and over which a filter gauze 8 is applied. distance from the center part 3 between the border parts 4 of the frame.
The two border parts are further provided with openings 9 for the rivet connection 10.
In the example of an embodiment according to the invention, between the border parts 4 which extend parallel to the longitudinal direction of the profile, a strip 11 is placed, which in this example of an embodiment is placed within a slot 12, which is present in both border parts. The strip is mounted in the border parts by means of a weld connection 13.
As shown in FIG. 4, multiple strips may be placed in the longitudinal direction of the profile, for example in a bent section of the profile.
