Rare earth fluorination furnace temperature control system based on single-chip microcomputer

Abstract

The invention relates to a rare earth fluorination furnace temperature control system based on a single-chip microcomputer and belongs to the field of industrial control. The system comprises an inputmodule, an LCD display screen, an alarm module, I / O interfaces, a single-chip microcomputer, an A / D converter, a thermocouple temperature sensor, a heating module and a rare earth fluorination furnace. The input module 1, the LCD display screen and the alarm module are connected to the I / O interfaces of the single-chip microcomputer. The thermocouple temperature sensor is embedded on an inner wall of the rare earth fluorination furnace, and an output end of the thermocouple temperature sensor is connected to an input end of the A / D converter. An output end of the A / D converter is connected toan input end of the single-chip microcomputer. The heating module comprises a gas supply pipe and a valve installed on the gas supply pipe, the gas supply pipe is connected to a gas inlet end of therare earth fluorination furnace, and the valve is connected to an I / O interface of the single-chip microcomputer. The rare earth fluorination furnace temperature control system has the advantages of convenient control, simple equipment and a fast response speed, and the economic benefits of chemical companies can be improved.

Description

technical field [0001] The invention relates to a single-chip microcomputer-based rare earth fluorination furnace temperature control system, which belongs to the field of industrial control. Background technique [0002] The vigorous development of the rare earth industry in my country not only meets the needs of my country's domestic economic development, but also provides important assistance to the supply of rare earths around the world. It can be seen that China has played a very important role in the development of the global rare earth industry and has a pivotal position in the world's rare earth industry. To develop China's manufacturing industry, the development and utilization of rare earths is indispensable. Rare earth materials, related equipment, green lamps, micro motors, nickel-metal hydride reuse batteries and other terminal products produced in China are used to meet the needs of the development of high-tech industries. In many developed countries around the...
