Abstract

The invention relates to an automatic feeding system for chemical production. The automatic feeding system comprises a feeding component, an online density measurement component, a differential pressure type liquid level measurement component and a pressure type flow sensor component. Problems about more on-site personnel, rough management, high potential safety hazard, frequent occurrence of safety production accidents and injuries to the personnel can be solved, problems about high randomness of on-site personnel in operation control, poor control accuracy, great affection on product quality, high production cost of products, failure in being effectively applicable to chemical industrial development and meeting safety requirements on the chemical production and the like are solved, product links can be effectively monitored and controlled, on-site personnel can be greatly reduced, and modern chemical production safety requirements are conformed to.

Description

technical field [0001] The invention belongs to the technical field of chemical equipment and relates to a feeding system, in particular to an automatic feeding system for chemical production. Background technique [0002] At present, with the development of measurement and control technology and the high toxicity, high corrosion, high flammability and explosiveness of raw materials in chemical production, it is very dangerous for on-site personnel to operate; Production has higher and higher requirements for the control system; therefore, the automatic feeding system of chemical production is required to effectively measure and control the production process, and at the same time greatly reduce the number of on-site operators, which meets the safety requirements of modern chemical production; in the past, due to backward technology and control Due to technical limitations, there are a large number of on-site workers in industrial production, extensive management, high poten...
