Embodiment Construction

[0040] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] see Figure 1 to Figure 5 As mentioned above, a roll-type filter membrane assembly disclosed by the present invention includes a central tube 1 and a filter element 2 wound on the central tube 1, such as image 3 shown.

[0042] Wherein, the filter element 2 is formed by repeated stacking of continuous single sheets formed by successively stacking guide cloth 21, filter membrane 22 and grid 23, as figure 1 , figure 2 and image 3 As shown, one end of the stack with creases is tightly attached to the central tube 1 in turn, and the creases are parallel to the central tube 1 .

[0043] The side of the guide cloth 21 in contact with the filter membrane 22 is denser and smoother than the other side, so as to protect the filter membrane 22 .

[0044] The both sides of guide cloth 21 are coated with sealant 3, as figure 1 and figure...

Abstract

The invention discloses a coil-type filter membrane assembly. The coil-type filter membrane assembly comprises a central pipe and a filter element wound on the central pipe, wherein the filter element is formed by repeatedly stacking a continuous single diaphragm formed by successively laminating guiding cloth, a filter membrane and a grid, one end, which is provided with creases, of the stacked article is successively adhered onto the central pipe, and the creases are parallel to the central pipe. The invention also discloses a manufacturing method of the coil-type filter membrane assembly. The coil-type filter membrane assembly is stable in structure, simple in production process, high in yield and convenient for automatic production.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a roll-type filter membrane module and a manufacturing method thereof. Background technique [0002] The main advantages of roll-type membrane modules are high packing density, easy operation and consistent industry standards. Rolled membrane elements are mainly made of flat membranes, including flat membranes, feed grids, dialysate grids, glue and dialysate collection tubes and other components. [0003] The common household roll-type membrane structure is made of a plurality of membrane bags wound on an engineering plastic central water collection pipe with holes. Each membrane bag is composed of two opposite membranes, a layer of polyester fiber woven freshwater grid is sandwiched between the membranes, and the three sides around the membrane are sealed with epoxy or polyurethane adhesive, and the fourth side is reserved as a water channel Connects to the central hea...
