[0002] Nanofiltration membranes are usually prepared by an interfacial polymerization reaction between the water phase and the oil phase on the membrane surface. The interfacial polymerization reaction usually requires heating to control the cross-linking density and structure of the functional layer.

[0003] For example, announcement No. CN219410008U proposes a mechanical wire-discharging device for hollow fiber membranes, including a wire-feeding barrel, a shell, a guide wheel, a wire-winding wheel, a tension-adjusting assembly and a heating and insulation assembly; the wire-feeding barrel is located on the right side of the shell, a wire-discharging element is provided on the left side of the shell, the membrane wire passes through the shell from the wire-feeding barrel and enters the wire-discharging element, a guide wheel is provided on the right side of the shell, a wire-winding wheel is provided on the left side of the shell, a tension-adjusting assembly is provided between the shell and the wire-discharging element, and the tension-adjusting assembly includes an extension plate, an adjusting wheel and an adjusting rod.

[0004] Due to the low curvature of the hollow fiber nanofiltration membrane, the uniformity of the coating cannot be controlled by the heating and insulation components in the above patent.

[0005] Based on this, the utility model designs a hollow fiber coating heating device to solve the above problems. Utility Model Content

[0022] The hollow fiber membrane filaments of the utility model enter the heating box from the filament inlet and exit from the filament outlet. The hot air furnace temperature control box blows hot air of a certain temperature into the wind uniform dispersion chamber through the air inlet through a pipeline.
