Abstract
A grid bar for a screen grid of a screen includes a multiple number of grid bars arranged next to each other and spaced apart from each other, which serves the purpose of separating screening material from a flowing liquid, such as wastewater flowing in a sewer channel. The grid bar includes a plastic reinforced with fibers, whereas at least a part of the fibers extend in a longitudinal direction of the grid bar. A screen includes such a screen grid.
Claims17
A screen grid of a screen for separating and removing bulk screening material from a flowing liquid, the screen grid occupying generally a longitudinal dimension and a transverse dimension disposed perpendicular to the longitudinal dimension, and with the longitudinal dimension being longer than the transverse dimension, the screen grid comprising:
- a plurality of grid bars arranged next to each other and spaced apart from each other, which serves the purpose of separating screening material from the flowing liquid, each grid bar being defined in part by a front side and a back side spaced apart in the longitudinal dimension from the front side, each grid bar extending parallel to one another in the longitudinal dimension;
- and
- wherein each grid bar includes, at least partially, a plastic reinforced with a plurality of fibers, whereas at least a majority of the plurality of fibers are arrayed with their lengths extending parallel to one another in the longitudinal dimension of the grid bar;
- and
- wherein each grid bar of the plurality of grid bars includes an outer protective layer formed of at least one woven fabric embedded in a plastic resin and covering at least a portion of the front side.
Screen for separating and removing screening material from a flowing liquid, such as that from wastewater flowing in a sewer channel, the screen comprising:
- a screen grid for separating and removing bulk screening material from a flowing liquid, the screen grid occupying generally a longitudinal dimension and a transverse dimension disposed perpendicular to the longitudinal dimension, and with the longitudinal dimension being longer than the transverse dimension, the screen grid including a plurality of grid bars arranged parallel next to each other and spaced apart from each other, each grid bar being defined in part by a front side and a back side spaced apart in the longitudinal dimension from the front side, each grid bar includes an outer protective layer formed of at least one woven fabric embedded in a plastic resin and covering at least a portion of the front side;
- and
- wherein at least each of a plurality of the grid bars includes a plastic reinforced with a plurality of fibers, whereas at least a majority of the plurality of fibers are arrayed with their lengths extending parallel to one another in the longitudinal dimension of the grid bar.
