Abstract

An on-line automatic analysis device for spinning bath components, comprising a man-machine operation unit, an electrical control unit, a sampling unit, an analysis unit and an automatic cleaning unit, the sampling unit includes a sampling cup, a sampling solenoid valve and a peristaltic pump; the analysis unit includes Stirrer, PH meter and two standard liquid storage tanks; the man-machine interface is connected with the electric control unit, and the electric control unit is respectively connected with the solenoid valve, the stirrer, the peristaltic pump and the PH meter. This automatic analysis device and method for spinning bath components can not only realize online automatic analysis of spinning bath components, but also perform online automatic flushing of its equipment without manual on-site sampling, reduce labor intensity of workers, and improve work efficiency and safety Coefficient, calculation and comparison measurement, eliminating manual measurement errors, improving measurement accuracy, suitable for spinning enterprises of all sizes.

Description

technical field [0001] The invention relates to the technical field of viscose staple fiber measuring instruments, in particular to an on-line automatic analysis device for the components of a spinning bath, and an analysis method based on the device. Background technique [0002] With the improvement of the technical level in the production process of viscose staple fiber, the inspection and treatment methods of the spinning bath components in the process are still in a backward way. Technologists need to go to the site to collect the liquid and perform manual detection and analysis. The work is intensive and the process is complicated, which is more likely to cause deviations in the detection results. SUMMARY OF THE INVENTION [0003] The present invention is aimed at the technical deficiencies mentioned in the background art. One is to provide a device that can realize the online automatic analysis of the components of the spinning bath and has the function of online au...
