Abstract

An on-line automatic analyzing device for spinning bath components comprises a human-machine operation unit, an electrical control unit, a sampling unit, an analyzing unit and an automatic cleaning unit. The sampling unit comprises a sampling cup, sampling electromagnetic valves and peristaltic pumps; the analyzing unit comprises a stirrer, a PH meter and two standard liquid storage tanks; a human-machine operation interface is connected with the electrical control unit, and the electrical control unit is connected with the electromagnetic valves, the stirrer, the peristaltic pumps and the PH meter. According to the on-line automatic analyzing device and method for the spinning bath components, not only can on-line automatic analyzing on the spinning bath components be achieved, but also on-line automatic cleaning of the equipment can be achieved, manual field sampling is not needed, the labor intensity of workers is lowered, and the working efficiency and safety coefficient are improved; by calculating and comparing measurement, manual measuring errors are avoided, the measuring precision is improved, and the device and method are suitable for being used by spinning enterprises of various scales.

Description

Technical field [0001] The invention relates to the technical field of viscose short fiber measuring instruments, and in particular to an online automatic analysis device for spinning bath components, 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 processing methods of the spinning bath components in the process are still in a backward way. Technicians need to perform manual inspection and analysis after taking the liquid on site. The work intensity is high, the process is complicated, and it is easier to cause deviations in the test results. Summary of the invention [0003] The present invention addresses the technical deficiencies mentioned in the background art. One is to provide a device that can realize online automatic analysis of spinning bath components and has an online automatic flushing function, and the other is to provide an ana...
