Liquid supply device for online mixing of spinning liquid

Abstract

The invention relates to a liquid supply device for online mixing of a spinning solution. The liquid supply device comprises a liquid storage tank, two delivery pumps, a three-way joint, a length adjusting device, a mixed liquid supply pipeline, a viscosity sensor, a signal processor and a variable frequency driver, in the spinning solution conveying process, the viscosity sensor monitors the viscosity of a spinning solution in real time and transmits viscosity data to the signal processor, the signal processor analyzes and processes the collected viscosity data and then sends an adjusting instruction to the variable frequency driver, the variable frequency driver controls the pumping speed of the two conveying pumps, and the conveying speed of the spinning solution is adjusted. Therefore, the content of the polymer solution and the auxiliary solution is controlled. The signal processor can also control the length adjusting device, as the grooves are connected with the protrusions in a clamped mode, the mixed liquid supply pipeline can be collected into the sleeve or released out of the sleeve by controlling the crawler belt strips to rotate, and therefore the length of the mixed liquid supply pipeline which is located outside the sleeve and actually used for online mixing is changed. Therefore, the mixing efficiency of the polymer solution and the additive solution is controlled.
