Method for monitoring deflection degree of glass lining reaction kettle stirrer

Abstract

The invention discloses a method for monitoring the deflection degree of a stirrer of a glass lining reaction kettle. The method comprises the following steps: installing a current sensor on a servo motor, and respectively installing vibration sensors in six directions of a glass lining reaction kettle to form a data acquisition device; judging whether the glass lining reaction kettle is in an operating state or not according to the current signal, determining whether the vibration sensor collects and the collection period, and performing edge calculation processing on the collected vibrationvalue data to obtain a vibration value and vibration spectrum data; identifying characteristic frequency and amplitude anisotropy characteristics reflecting inclination of the stirrer in the vibrationspectrum data, and calculating an inclination angle of the stirrer of the glass lining reaction kettle according to the vibration characteristics; analyzing abnormal characteristics of current when the stirrer inclines, and calculating inclination angle characteristics of the stirrer according to the current characteristics; vibration and current calculation results are comprehensively applied, and inclination angle abnormal information of the stirrer of the reaction kettle is sent to on-site operators in real time to remind attention.

Description

technical field [0001] The invention belongs to the technical field of electromechanical equipment safety monitoring, in particular to a method for monitoring the deflection degree of a glass-lined reactor stirrer. Background technique [0002] Reactor is an important physical or chemical reaction vessel, which mainly realizes the functions of heating, evaporation, cooling and low-speed mixing. Glass-lined reactor is a common type of reactor, mainly used in petroleum, chemical, food, pharmaceutical, pesticide and other industries. In terms of mixing function and effect, the reactor has more advantages than ordinary containers in terms of sealing, constant temperature, constant pressure, mixing speed, etc. The glass layer has advantages in terms of constant temperature and mixing speed. The glass-lined layer is most likely to be scratched and damaged by the blades of the agitator. Once the glass-lined layer is damaged, the production efficiency of the reactor will be severel...
