  • Patent number: 5300221
    Abstract: The filter arrangement is provided with a filter in the form of an endless conveyor which is releasably mounted within a transport chute through which a flow of water can be directed. The filter is formed as a unit to be released from supports at the bottom of the transport chute for ease of cleaning. The filter is further pivotally mounted at the lower end so as to be adjusted angularly relative to the flow of water through the transport chute. Seals are provided between the sides of the filter and the side walls of the transport chute to preclude passage of liquid. A plurality of such filters may be disposed within the transport chute and may be associated with various discharge conveyors for discharging materials which have been filtered out of the flow of liquid.
