摘要

Complementary filters for pool water purification equipment, characterized in that they have a frusto-conical configuration, with the largest open base and the lowest closed, and, of such dimensions, that the larger one perfectly adapts to the inner profile of the pre-filter basket of the "skimmer" (see figure 1), and, the smallest, which also perfectly fits the pre-filter attached to the suction pump (see figure 2). Both complementary filters are technically the same, varying only in their dimensions, and they are constituted entirely by a net of very dense mesh, capable of retaining the finest needles that the coniferous plants give off. The nets will be constructed preferably of stainless steel or nylon, being able to admit any other material that resists the action of the chlorine and other chemical products, used in the purification of the water. The networks that constitute each complementary filter may be integral, or in two pieces, on one side the frustoconical lateral surface, and, on the other, the circular base, although both pieces will be joined and overlapping, so that they do not leave any crack, through which the needles can pass. In case the nets are made of nylon, or other material that is not sufficiently rigid, they must have a plastic adapter inside (see figures 3 and 4), which conform and facilitate their perfect adjustment to the basket. The prefilters. Said adapter must be a frame, as simple as possible, provided with large openings, so that it does not resist hardly any resistance to the passage of water.
