Below in conjunction with the accompanying drawings the intelligent paint stripping furnace automatic control system of the present invention is described further.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of intelligent paint stripping furnace automatic control system of the present invention；
Fig. 2 is the workflow diagram of intelligent paint stripping furnace automatic control system of the present invention.
Detailed description of the invention
As it is shown in figure 1, intelligent paint stripping furnace automatic control system of the present invention includes host computer, slave computer, two sleeving temperature detector units, two set pressure sensing cell and two flame detectors, host computer is industrial computer, and industrial computer includes main frame and touches display screen；Slave computer is that PLC, PLC are communicated with industrial computer by RS485 interface.Temperature detecting unit includes thermocouple and temperature transmitter；Pressure sensing cell includes that pressure transducer, pressure transducer, thermocouple and temperature transmitter are connected with PLC by connecting cable.Two sleeving temperature detector units and two set pressure sensing cells are respectively used to detect the temperature and pressure of two combustor of paint stripping furnace, two flame detectors are for detecting the firepower size of two combustor of paint stripping furnace, and detect two temperature of combustor, pressure data and firepower state are sent to slave computer, host computer is read chamber temperature, pressure data and the firepower state of slave computer storage by COM1 and is shown by interface software, and slave computer regulates the firepower size of two combustor according to the temperature and pressure data of two combustor detected.
Slave computer regulates firepower according to the temperature dynamic of first-stage firing chamber, ensure that the temperature and pressure of single-stage combustion indoor is in safety range, slave computer is used for controlling the waste gas evaporation rate that single-stage combustion is indoor according to the temperature of the process status adjustment first-stage firing chamber of secondary combustion chamber simultaneously, ensureing secondary combustion chamber's steady load, slave computer judges the exhausted air quantity processed according to rate of temperature change and the combusting firepower size of secondary combustion chamber and can realize being automatically stopped.
As in figure 2 it is shown, PLC is by analog-to-digital conversion module collecting temperature, the analog data of pressure sensitive unit, analyzing current processing status, real-time update is stored in internal storage unit.Industrial computer reads the temperature that PLC monitors, pressure, process state information in real time by RS485 interface and shows in interface software.The waste gas release temperature of first-stage firing chamber is 400 DEG C; applicable pressure is 0.1MPa; by thermocouple and pressure transducer thereof monitor in real time single-stage combustion room temperature, pressure data and using Monitoring Data as first-stage firing chamber burner firepower regulate reference data; make single-stage combustion room temperature maintain 400 degrees Celsius, protected by explosion proof door simultaneously.
Object processes the initial stage, control system makes first-stage firing chamber be stable at 500 DEG C by pid algorithm, after the waste materials such as the paint on workpiece start normally to decompose, firepower needed for the burner combustion waste gas of the secondary combustion chamber of monitoring in real time, when needed for secondary combustion chamber's burner, firepower is less than setting value, showing that first-stage firing chamber release exhaust rate reaches the saturated process load condition of secondary combustion chamber, the burner firepower that should suitably turn first-stage firing chamber down makes secondary combustion chamber be less than rated load operation.PLC dynamically regulates firepower by monitoring secondary firing indoor rate of temperature change in real time makes waste gas burning abundant, when secondary combustion chamber's burner firepower is more than setting value, shows that first-stage firing chamber waste material volatilizees completely, is then automatically stopped through suitable time-delay burning.
Embodiment described above is only to be described the preferred embodiment of the present invention; not the scope of the present invention is defined; on the premise of designing spirit without departing from the present invention; various deformation that technical scheme is made by those of ordinary skill in the art and improvement, all should fall in the protection domain that claims of the present invention determines.
