Screen lining
A screen lining having an adapter strip for fastening a screen mat or two screen mats arranged adjacent to each other to a supporting substructure in such a way that the screen mat or screen mats can be replaced. The adapter strip has projections on the side of the adapter strip facing away from the screen mats, which projections are integrally formed on the adapter strip in order to be inserted into openings on the substructure and have a bearing region on the side of the projections facing the screen mats, in which bearing region at least one hollow for the form-fitting fastening of the screen mats is arranged. The adapter strip has integrated deflecting blades, the top sides of which are angled downward with respect to a plane defined by the screen mats.
1. A screen lining for a flip-flop screen comprising:
an adapter strip attached to a supporting substructure; and
one or two screen mats replaceably attached side by side to the adapter strip, each screen mat having a projection on a side facing towards the adapter strip,
wherein the adapter strip comprises:
projections formed on a side of the adapter strip facing away from the screen mats, the projections inserted into corresponding openings in the substructure;
a bearing region formed on a side of the adapter strip facing towards the screen mats, the bearing region having at least one recess for interlocking attachment of the screen mats, wherein the projections of the screen mats are inserted into the at least one recess of the bearing region of the adapter strip; and
integrated deflecting flaps, wherein top sides of the integrated deflecting flaps are angled downward with respect to a plane defined by the screen mats,
wherein a snap-lock connection is provided between the projections of the screen mats and the at least one recess of the adapter strip, so that the screen mats are secured to the adapter strip without additional fasteners.
2. The screen lining according to claim 1 , wherein a shape of the adapter strip and of the deflecting flaps is made to substantially correspond to outer contours of the substructure.
3. The screen lining according to claim 1 , wherein the adapter strip is provided with a V-shape.
4. The screen lining according to claim 1 , wherein undersides of the deflecting flaps of the adapter strip enclose an included angle of 60° to 90°.
5. The screen lining according to claim 1 , wherein the deflecting flaps bear against the substructure under tension due to spreading.
6. The screen lining according to claim 1 , wherein a free space is provided between the adapter strip and screen mats, outside the bearing region, as a space for a passage of material being screened.
7. The screen lining according to claim 1 , wherein the projections provided on the adapter strip are provided as slotted cylinders with spreadable jaws or as expanding anchors.
8. The screen lining according to claim 1 , wherein the recess on the adapter strip and/or a corresponding projection on the screen mats has a triangular shape with rounded corners.
9. The screen lining according to claim 1 , wherein the adapter strip and/or screen mats are made of plastic.
10. The screen lining according to claim 1 , wherein the adapter strip is reinforced in the bearing region by a U-shaped reinforcement or strengthening structure.
11. The screen lining according to claim 1 , wherein the recess on the adapter strip provides space for captured dirt particles.
12. The screen lining according to claim 1 , wherein the entire top side and an entire bottom side of each deflecting flap is formed as a flat, planar surface from an integrated end of the deflecting flaps to distal ends thereof.
13. The screen lining according to claim 1 , wherein each of the projections of the adapter strip has a through hole formed therethrough with a respective mounting screw extending through each through hole.
14. The screen lining according to claim 1 , wherein the projection of each of the screen mats has a triangular shape with rounded corners.
