Composite membrane machine for manufacturing flat membrane

Abstract

The invention discloses a device for manufacturing a flat membrane, in particular a composite membrane machine for manufacturing the flat membrane. The device is characterized by comprising an unfolding cloth charging unit, an immersion unit, a transport unit, a ventilating adjusting unit, a membrane manufacturing unit, a baking unit, a washing unit and a folding cloth discharging unit, wherein the unfolding cloth charging unit, the immersion unit, the transport unit, the ventilating adjusting unit, the membrane manufacturing unit, the baking unit, the washing unit and the folding cloth discharging unit are sequentially arranged in a streamline mode; and the transport unit is arranged on each function unit, and a plurality of groups of cloth guide rollers form a transport rail so that the base cloth can steadily run on the transport rail and is constantly processed by each function unit. The composite membrane machine for manufacturing the flat membrane is reasonable in structure and high in production efficiency, realizes streamline production of the non-woven flat membrane and is applicable to industrial promotion in a large scale.

Description

Technical field: [0001] The invention relates to a flat film production equipment, in particular to a flat film composite film machine. Background technique: [0002] At present, flat membranes are widely used in water treatment, environmental protection, and biochemical fields. Flat membranes can be used to prepare support membranes for ultrafiltration membranes, reverse osmosis membranes, and other composite membranes. Due to the smaller surface pores and cross-sectional pores with good permeability, the flat film has excellent tensile and impact resistance properties. [0003] The preparation method of the flat film has been demonstrated by various experiments. In the published Chinese patent application (application number is 200710067860, 200810061236), the non-woven fabric is used as the base material, and the non-woven fabric is coated with a special preparation method. Membrane solution can be prepared. [0004] Although the preparation method of flat film has beco...
