Machine for the removal of coarse matter in flowing liquids - flat filter band rake

摘要

In the case of the filter band rake, the filter baskets 2 of the filter belt transversely to the flow direction, therefore, the flow of liquid is twice through the filter baskets 2 currents. The individual filter baskets 2, by means of pulling bushings conveying chains 1 connected to filter bands. For this reason, as a result of the wear to the chain to an increase of the gap between the filter baskets 2, the cleaning performance deteriorates continuously.In the case of the flat filter band rake, the filter baskets 2 parallel to the direction of flow. By means of the angle of inclination and the length of the filter baskets 2, the surface area of almost arbitrarily increased, thus be adapted to the desired cleaning performance. The filter baskets 2, by means of a wear resistant roll - connected to one another, and system. The drive is effected by means of special thrust pawls wheels 13. the filter baskets 2 are pressed by the flow of liquid, for which reason there are no gap enlargements due to wear can occur between them. The tightly - and sliding gaps at the top ends of the filter baskets 2 are determined by the inclination of the filter belt automatically adjustable manner, so that there is no wear to which is decreasing cleaning performance. The cleaning of the filter baskets takes place on the water side instead of dirt. As a result, there is no, depending on their design possible, dirt particles on the entrainment of silver. Flooding of the flow channel is indicated by the installation of a water state as a function (float 26) via barrel opening flap 21 is not possible. Filter belt - and flat filter band rakes are cuts in the form of a trough. 9 shown.n="19"
