Problems solved by technology

[0004] 1. The fabric guide rollers in the coating unit are all fixed, which cannot adjust the water entry angle and time of the base fabric according to the needs, thus affecting the quality of film production;
[0005] 2. The coating unit uses the scraping head and the coating roller to complete the scraping, but because the position of the scraping head and the coating roller is relatively fixed, the thickness of the coating film cannot be controlled, and the scraping head cannot be lifted. easy to break;
[0006] 3. The coating unit cannot effectively cool the film after the film production is completed, so that the gelation speed of the film is slow
[0007] 4. The unwinding progressive unit needs to be reloaded after the cloth conveying is completed, which reduces the production efficiency of the equipment

Abstract

The invention relates to coating equipment for a flat sheet membrane. The coating equipment comprises a feeding device, a gluing and gelating device, a water washing device and a rolling device, wherein the feeding device, the gluing and gelating device, the water washing device and the rolling device are sequentially connected to realize continuous production. The coating equipment for the flat sheet membrane, which is disclosed by the invention, has the advantages of capabilities of lifting, controlling the coating thickness and adjusting the angle of base cloth entering water, high gelating speed, high production efficiency, high membrane preparation quality and the like.

Description

technical field [0001] The invention relates to a flat film production equipment, in particular to a flat film coating equipment. Background technique [0002] Flat membranes are widely used in sewage treatment, biochemical and other fields, and 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] Please refer to the People's Republic of China Invention Patent No. 201010597417.2 for the prior art flat film production equipment. However, there are following defects in the above-mentioned flat film production equipment: [0004] 1. The fabric guide rollers in the coating unit are all fixed, which cannot adjust the water entry angle and time of the base fabric according to the needs, thus affecting the quality of film production; [0005] 2....
