A production device for electrostatic hang coating ultrafiltration membrane by solvent method

Abstract

The invention discloses a production device for electrostatic hang-coating ultrafiltration membrane by solvent method, which comprises a No. 1 bearing platform, the upper surface of the No. A No. 1 N-shaped frame is installed, and the upper surface of the No. 1 N-shaped frame is covered with an unwinding drum. The upper surface of the strip-shaped workbench and the right side of the No. 1 N-shaped frame are provided with a No. 2 N-shaped frame. The No. 1 N-shaped frame is set with a winding drum, and the two opposite side surfaces of the No. 1 N-shaped frame are fixedly connected with L-shaped fixed rods, and each of the L-shaped fixed rods is provided with a horizontal circular shaft on one end surface. A No. 1 guide wheel is set on each of the horizontal circular shafts, and a No. 1 gantry is embedded in the other end of the upper surface of the bar-shaped workbench. The beneficial effect of the invention is that it is a device that is more convenient to operate, more evenly sprayed, reduces labor intensity, improves production efficiency, can reuse materials, and can better accept waste materials.

Description

technical field [0001] The invention relates to the field of ultrafiltration membrane production, in particular to a production device for electrostatic hang-coating ultrafiltration membranes by solvent method. Background technique [0002] The ultrafiltration membrane is an item used for filtration. The quality of the ultrafiltration membrane determines the filtering effect. [0003] At present, the shortage of water resources and the pollution of water environment in my country are becoming increasingly serious, which has become one of the main factors restricting the stable development of my country's economy and society. The state and local governments have formulated stricter sewage discharge standards and drinking water standards, and water treatment The technology has put forward new and higher requirements, and at the same time, it has also increased investment in new sewage (waste) water advanced treatment technologies and processes. As the core unit filter cloth of ...

[0003] At present, the shortage of water resources and the pollution of water environment in my country are becoming increasingly serious, which has become one of the main factors restricting the stable development of my country's economy and society. The state and local governments have formulated stricter sewage discharge standards and drinking water standards, and water treatment The technology has put forward new and higher requirements, and at the same time, it has also increased investment in new sewage (waste) water advanced treatment technologies and processes. As the core unit filter cloth of water treatment equipment, it has been facing problems such as low production efficiency and serious secondary pollution. The manufacturing cost is high, and the traditional technology is unevenly applied, and when spraying, there will be excess spraying material on the edge, which needs to be scraped off manually, which is relatively strong and inefficient for the operator , when combining the original material of the filter cloth with the spraying material, it is usually heated and sprayed with a tool manually, which is likely to cause unevenness and affect the result, and there are too many waste materials that cannot be reused, and it is not convenient to collect waste materials. Therefore, in order to solve these problems, it is necessary to design a new type of production device
