| Ceramic is an important part of Chinese cultural heritage and enjoys a high reputation at home and abroad. In the history of the development of Dehua ceramics, technologies to enhance the precision of temperature control and to realize the automation in ceramic production are especially focused. With the rapid development of computer technology and power electronics technology, High automation and intellectualization of temperature control technology are more widely and more mature.The intelligent temperature controller, with single chip microcomputer and PID self tuning function, as its advantages of powerful function, small size, simple operation, low cost have been widely used in ceramic production.The temperature control system of the shaft kiln is analyzed in detail., On the basis of investigating the principle of temperature control firing process curves and understanding of the development of modern temperature control technology, this paper proposes a control scheme of well type kiln temperature, which consists of intelligent digital display temperature controller as the core, silicon elements as the executive component and thermocouple as temperature measuring element.The main contents of this paper:1. Determining the design scheme of well type kiln temperature control system based on the analysis of the original temperature control system, the principles of the temperature control, process curve and understanding of the development of modern technology.2. Completing the selection of the intelligent temperature controller, thermocouple sensor, silicon controlled rectifier, current transformer, electric furnace wire, and establishing a well type kiln temperature control system.3.Discussing control algorithm and fuzzy control theory, for the actual work of the well type kiln parameter setting is now provided the necessary theoretical basis.4. Completing the temperature controller parameters setting, program, and well test kiln burning test. |
