Abstract

The invention discloses a device for producing hollow fiber membranes. The device comprises a support. A spinneret, a lower joint and an upper joint are arranged successively from bottom to top on the support. A membrane material liquid inlet is arranged on the upper joint, and a membrane core liquid inlet is arranged on the lower joint. The upper joint and the lower joint are sealed through seal rings, and a spinneret orifice is arranged on the spinneret. The device for producing hollow fiber membranes is characterized in that the spinneret is a rotary spinneret, and rotary bearings are arranged at connection positions of the rotary spinneret with the lower joint and the support. The device further comprises a power unit and a transmission unit. The power unit is arranged on the support and connected with the rotary spinneret through the transmission unit. The invention further comprises a method for producing hollow fiber membranes. The device for producing hollow fiber membranes can be used for producing hollow fiber membranes through an immersion precipitation phase process or a thermal induced phase separation process, the structure is simple, manual adjustment is not used, the quality and the stability of hollow fiber membranes are improved greatly.

Description

technical field

[0001] The invention relates to the field of hollow fiber membrane production, in particular to a hollow fiber membrane production device and a hollow fiber membrane preparation method. Background technique

[0002] Hollow fiber membranes are widely used in filtration or dialysis in various fields such as industrial and municipal sewage treatment, drinking water purification, reclaimed water reuse, food processing and biomedicine. At present, the following problems mainly exist in the spinning process of hollow fiber membranes: 1) uneven thickness of the membrane wall; 2) poor transverse strength of the membrane; 3) poor uniformity and stability.

[0003] In "Modern Membrane Technology and Its Application Guide" (July 2005, Chemical Industry Press, edited by Wang Xuesong), "Chapter 4 Preparation Process of Various Configuration Membranes" in the "Second Membrane Production Process" 4.4.2 The spinning head device of the hollow fiber membrane is introduced in ...
