  • Spray nozzle assembly for filter devices
    Patent number: 4397694
    Abstract: A spray nozzle assembly for spraying washing liquid onto a moving surface of a filter cake. The respective spray nozzles are communicated with a pressurized source of wash liquid, and are arranged adjacent the filter cake in successive doubled rows. The latter are laterally aligned normal to the direction of the filter cake movement. Corresponding spray nozzles of the respective rows are so aligned to define a plurality of nozzle lines which deviate from a parallel relationship with the path of travel of said filter cake.
