Intelligent temperature control calcining furnace based on data feedback

The utility model discloses an intelligent temperature control calcining furnace based on data feedback, which comprises a calcining furnace, the calcining furnace is provided with an air door actuator, the furnace temperature is measured by a photoelectric thermodetector, the measured data is transmitted to a data server, the air pressure of the air door actuator is measured by an air pressure sensor, and the measured data is transmitted to the data server. The server divides furnace temperature data and air pressure data into two paths and transmits the two paths to the PLC and the displayer respectively, the PLC compares the furnace temperature data with preset temperature and gives out a working instruction to the air door actuator in combination with the air pressure at the air door actuator, and the air door actuator adjusts the opening degree of a valve after receiving the instruction so as to adjust the air pressure; according to the intelligent temperature control calcining furnace, the air inlet amo
