Casting knife of ion membrane steel strip casting machine with opening and closing function

Abstract

The invention discloses a tape-casting cutter having a start and stop function and used for an ionic membrane steel belt tape-casting machine. The tape-casting cutter comprises an installation plate (1). Hanging frames (5) are connected below the installation plate (1). A cutter frame (7) is connected between the hanging frames (5). One end of a coarse tuning rod (8) is fixed to a beam (13) of the cutter frame (7), and the other end of the coarse tuning rod (8) penetrates a hole of the installation plate (1) and stabilizes the cutter frame (7) through a surface bearing (9) and a butterfly nut (10). The cutter frame (7) comprises a cutter base (14) which is provided with a plurality of feed holes (36) and a plurality of vent holes (37). A plurality of feed pipes (12) penetrate pipeline holes in the installation plate (1) and communicate with the feed holes (36). A plurality of exhaust pipes (11) penetrate pipeline holes in the installation plate (1) and communicate with the vent holes (37). The tape-casting cutter solves the problems that ionic membrane slurry needs to be de-foamed after entering a cutter body before tape-casting, and cleaning is needed due to the fact that the remaining slurry drips onto steel belts after tape-casting is finished; and the requirement for batched and continuous production is met, manpower is reduced, and the labor intensity is lowered.

Description

technical field [0001] The invention relates to a manufacturing device of an ionic membrane, in particular to a casting knife of an ionic membrane steel strip casting machine with an opening and closing function. Background technique [0002] In industries such as hydrogen production by water electrolysis, fuel cells, and chlor-alkali electrolysis, most of the membranes used for ion exchange are perfluorinated ion exchange membranes. The batch continuous production method of this product mainly adopts casting method. The casting method is to dissolve the raw material in an organic solvent, adjust it into a viscous solution, cast it on a flat and uniform smooth rotating body, and form a film by baking. The film processed by this method has good uniformity and a smooth surface. , the advantage of good performance. However, with the current casting equipment, since the slurry for producing perfluorinated ion exchange membranes enters the cavity of the casting knife, it cannot ...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a casting knife of an ionic membrane steel strip casting machine with an opening and closing function, so as to solve the problem of defoaming and remaining after the perfluorinated ionic membrane slurry enters the knife body before casting. The problem of slurry dripping onto the steel belt needs to be cleaned up. It is simple and convenient to use, improves efficacy, reduces labor intensity, and meets the requirements of mass production.
