Wet spinning solution premixing and delivery device

Abstract

The invention discloses a wet spinning solution premixing and delivery device, which is characterized in that: the device sequentially utilizes a first charging barrel (1) and a second charging barrel (2) to be connected with the inlet end of a dynamic mixer through a first metering pump (3), a first filter (5), a second metering pump (4) and a second filter (6) respectively, wherein the outlet end of the dynamic mixer is connected with a spinning metering pump through a pipeline to spin; a motor (8) of the dynamic mixer is connected with a third frequency converter (14); and the pipeline is respectively connected with a first frequency converter (12) and a second frequency converter (13) through a valve, a pressure transmitter (9), a multifunctional controller (10) and a synchronous controller (11), and the first frequency converter and the second frequency converter are respectively connected with the first filter (5) and the second filter (6). The wet spinning solution premixing and delivery device has the advantages of simple structure, convenience in assembly, easiness in operation control and strong mixing capability, and is applicable to producing various wet spinning composite fibres, functional fibres, special fibres and various diversified fibre products.

Description

technical field [0001] The invention relates to a pre-spinning mixing and conveying device for wet spinning dope. It belongs to the field of metering, mixing and conveying of raw liquid and additives of wet spinning. Background technique [0002] There are many types of wet spinning products, the main varieties are acrylic fiber, vinylon, viscose fiber and so on. These types of fiber spinning dope are often added with some functional additives and then spun to produce various differentiated and functional fibers, such as flame retardant, heat preservation, coloring, phase change, far infrared, sterilization, antistatic, etc. Functional fiber. Or the spinning dope of several polymers is blended and spun to prepare composite fibers, such as vinylon, acrylic, collagen fiber, soybean protein fiber, milk protein fiber, rapeseed protein fiber and so on. The preparation process of these functionalized fibers or composite fibers involves the mixing preparation and transportation ...

Problems solved by technology

However, due to the use of static mixers for mixing, it is difficult for this system to achieve relatively uniform mixing for systems with high fluid viscosity, slow flow rate, and poor material compatibility.
