DCS control system for material processing

Abstract

The invention provides a DCS control system for material processing. The system comprises a diaphragm pump arranged on a material storage tank and a motor used for starting material processing, an electromagnetic valve is arranged on the diaphragm pump, and a detection module is arranged inside the material storage tank. The detection module is in interactive connection with a PLC via an analog I / O module, the programmable logic controller is in interactive connection with a digital I / O module, the digital I / O module controls operation of the diaphragm pump through the electromagnetic valve, the output end of the electromagnetic valve is connected with the input end of the digital I / O module, and the output ends of the analog I / O module and the digital I / O module are both connected with the motor. According to the DCS control system for material processing provided by the invention, material weighing, material feeding, and the temperature, liquid level and the like inside the material storage tank in the process of material stirring, dispersing or grinding can be automatically and remotely controlled, a processing device can be automatically started or stopped, the purpose of automatic processing is achieved, the cost is saved, and the product quality is improved.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to a DCS control system for the production steps of materials in the processing process. Background technique [0002] With the continuous rise of modern large-scale industrial production automation and the increasingly complex requirements of process control, a comprehensive control system for production management and process control, which combines computer technology, system control technology, network communication technology and multimedia technology, has emerged as the times require. system to achieve the purpose of automated management. [0003] In the process of chemical production, it is often necessary to mix or grind various materials such as active ingredients, dispersants, emulsifiers, preservatives, etc. Before mixing or grinding, the mass of solid materials must be weighed, and the mass of liquid materials should be weighed. It is measured, and then added to the sti...

Problems solved by technology

This poses a great challenge to the current manual control, because the mixers or grinders used in production and processing in factories are relatively large, and the weight of each processing is relatively heavy. If these controls all rely on workers to realize feeding and metering, When measuring temperature and liquid level and other functions, it not only increases the workload of workers, but more importantly, it is easy to cause errors in feeding, metering or measurement during the production process, which will lead to unqualified products in the final process.
