Description

Technical Field

[0001] The utility model relates to a cooling trough, in particular to a cooling trough for hollow fiber membrane production, belonging to the technical field of hollow fiber membrane production. Background Art

[0002] Hollow fiber membrane refers to a membrane that looks like a fiber and has a self-supporting function. The hollow fiber membrane is made of polysulfone and dimethylacetamide as raw materials to form a fiber filament with a hollow inner cavity, and then divided by a high permeability polymer. It has selective permeability characteristics. Since water vapor, hydrogen, ammonia and carbon dioxide permeate faster, while methane, nitrogen, argon, oxygen and carbon monoxide permeate slower, the fast-permeating and slow-permeating substances are separated. During the production of the fiber membrane, it needs to be cooled with a gel solution.

[0003] Among them, the "cooling trough for hollow fiber membrane production" disclosed in the application number "CN202321996338.8" "comprises a cooling pool, a plurality of partition plates fixedly installed inside the cooling pool to form a plurality of trough bodies side by side in the cooling pool, a limiting conveying component installed at the upper end of the cooling pool and arranged on both sides of the partition plates for changing the conveying direction of the hollow fiber membrane, and a downward pressing limiting component arranged in the middle section of the trough body for pressing the hollow fiber membrane down in the trough body". In the utility model, when the hollow fiber membrane is squeezed out and enters the cooling pool, the partition plate divides the cooling pool into multiple trough bodies, and colloidal solutions of different concentrations are placed in each trough body. The colloidal solution in the trough body decreases successively from one end close to the extruder to the tail end, thereby slowing down the release rate of soluble substances in the hollow fiber membrane entering the cooling pool, so that the hollow fiber membrane can form more pores and reduce the pore diameter.

[0004] However, the above method still has the following defects: the hollow fiber membrane is cooled by passing through colloidal solutions of different concentrations, but when the hollow fiber membrane passes through colloidal solutions of different concentrations for a long time, the temperature of the colloidal solution will gradually increase, and the lack of cooling settings will affect the cooling effect of the hollow fiber membrane.
