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.
Claims4
Apparatus for treating a surface of a filter cake with a liquid, which apparatus includes:
- means to progress the filter cake along a constant travel path,
- a nozzle array disposed adjacent to said travel path including a plurality of nozzles, each of which is adapted to form a cone shaped liquid stream, and to deliver the liquid in a circular pattern against the surface being treated, each of said nozzles being communicated to a pressurized source of the treating liquid whereby to impinge said streams of the liquid against the surface of said moving filter cake, such that no liquid circular pattern intersects any other circular pattern, said nozzle array comprised of;
- a plurality of nozzle row pairs including spaced apart primary and secondary nozzle rows which extend substantially normal to the travel path, said rows being "n" in number;
- nozzles in each of said primary and secondary nozzle rows being spaced laterally equidistant apart in the amount of "a" inches,
- the respective primary and secondary nozzle rows of said row pairs being substantially equally spaced one from the other and,
- corresponding nozzles in each primary and secondary rows being disposed in singular alignment with each other to define discrete lines of obliquity with respect to said path of travel, as determined by the ratio of approximately a/n.
Spray apparatus for spraying washing liquid against a filter cake, including a supply conduit communicated with a source of said washing liquid for supplying spray nozzles with wash liquid, said spray nozzles being arranged about the filter cake in a plurality of double rows disposed normal to the direction of the filter cake movement, the spray nozzles of the individual rows of a double row being provided in staggered arrangement, and the spray nozzles of all rows having equal distance one from the other, the improvement therein of said spraying nozzles of the double row being staggered in relation to those of an adjacent double row in the direction transversely to the direction of filter cake movement.
