CMF multi-layer film integrated device

The utility model provides a CMF multi-layer film integrated device, and relates to the improvement of a cleaning structure of a tubular ultra-filtration film. The integrated device comprises ultra-filtration films (1), raw water inlets (2), ultra-filtration film wire sealing compound (3), ultra-filtration film sealing systems (4), an ultra-filtration film water generating outlet (5), a movable cover plate (6), an ultra-filtration film upper water generating self-owned box (7), an ultra-filtration film inner cleaning medium upper inlet (8), an ultra-filtration film concentrated water outlet (9), an ultra-filtration film middle water generating self-owned box (10), an ultra-filtration film inner cleaning medium middle inlet (11), an ultra-filtration film raw water inlet (12), an ultra-filtration film lower water generating self-owned box (13), an ultra-filtration film inner cleaning medium lower inlet (14), a water flow opening (15), an integrated ultra-filtration film stainless-steel shell (16), a built-in laminate I (17), a built-in laminate II (18), a built-in laminate III (19), a built-in laminate IV (20), a lower working cavity (21) and an upper working cavity (22). By controlling the flow directions of water flowing in various tube holes, the conversion among the water generating working condition, the direct washing working condition and the back washing working condition is realized; the integrated device solves the technical difficulty of cleaning of the tubular ultra-filtration film, improves working efficiency, and particularly solves the difficult problem that the conventional tubular ultra-filtration film is low in water generating efficiency.
