The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

In addition, the technical solutions between the embodiments of the present invention can be combined with each other, but it is necessary to be able to be realized by a person having ordinary skill in the art as a basis, and when the technical solutions are contradictory or cannot be realized, the combination of such technical solutions should be considered to be absent, and is not within the protection scope of the present invention.

Referring to fig. 1 to 2, a continuous type filtration membrane shell structure group comprises a membrane shell body, wherein a water outlet cavity and an air inlet cavity are respectively arranged at the upper end and the lower end of the membrane shell body, a filtration cavity 5 is arranged in the middle of the membrane shell body, an air inlet 3 is arranged on the air inlet cavity, a water outlet 1 is arranged in the water outlet cavity, a thick water inlet 2 is arranged on the side wall of the filtration cavity 5, the filtration cavity 5 comprises a tube cavity 51 and a plurality of membrane wires 6, the tube cavity 51 is connected with a water inlet 4 arranged below the membrane shell body, a plurality of small holes are arranged on the tube cavity 51, and preferably, the tube cavity 51 penetrates through the air inlet; the membrane wires 6 are arranged outside the tube cavity 51, and two ends of the membrane wires are fixedly connected with the upper end and the lower end of the filter cavity 5 through polyurethane; the upper end and the lower end in the filter cavity are sealed by polyurethane; the inner cavities of the membrane filaments are communicated with the air inlet cavity and the water outlet cavity. Preferably, valves are arranged at the air inlet, the water outlet, the water inlet and the concentrated water outlet.

The application has the following action principle:

and (3) a normal process: source water enters from a water inlet 4, enters a filter cavity 5 in the membrane shell body through a tube cavity, flows out of a small hole in the cavity 51 to immerse the whole filter cavity 5, and through the external pressure type filtering principle, clean water enters an inner cavity of the membrane wire 6, flows into a water outlet cavity and enters an external container through a water outlet 1.
