Description
Technical field
The utility model relates to roasters, and in particular to a kind of carbon baking furnace of automatic control.
Background technique
Carbon baking furnace is that carbon product is carried out indirect heating by defined maturing temperature in the absence of air conditions
A kind of Thermal Equipment, roaster needs to light a fire when in use, lights combustion gas, combustion gas is mentioned by gas producer or gas pipeline
For then being introduced into roasting range control equipment by air-introduced machine, when air-introduced machine or pipeline gas break down, air-introduced machine cannot will just
In normal fuel gas transmission to burner hearth, so that it is excessive with the pressure difference in ventilation pipe in roaster, it is easy to cause tempering, flare meets combustion
Gas explodes in turn.
Utility model content
In view of the above technical problems, the purpose of the utility model is to provide the carbon baking furnaces that one kind can automatically control.
The technical solution of the utility model specifically:
A kind of carbon baking furnace of automatic control, including burner hearth are provided with ventilation pipe above burner hearth, ventilation pipe
One end is protruded into inside burner hearth, and ventilation pipe exit is provided with igniter, and igniter adjacent position is provided with electric thermo-couple temperature biography
Sensor, the end of thermocouple temperature sensor reach the front of igniter, and the other end of ventilation pipe is connected to air-introduced machine, air-introduced machine
It is connected to gas producer, is provided with concentration sensor and pressure sensor on ventilation pipe, the carbon baking furnace further includes PLC
Controller, igniter, thermocouple temperature sensor, air-introduced machine, gas producer, concentration sensor and pressure sensor with
PLC controller connection.
Be provided with proportional control valve on the ventilation pipe, concentration sensor and pressure sensor be located at proportional control valve and
Between air-introduced machine, proportional control valve is connect with PLC controller.
Temperature sensor is provided in the burner hearth, temperature sensor is connect with PLC controller.
Compared with the existing technology, the technical effect of the utility model is to automatically control furnace by being provided with PLC controller
The conveying of igniting and combustion gas inside thorax, realizes the automatic ignition of roaster, compares and saves manpower, cost and control with manual firing
System is accurate, and thermocouple temperature sensor is arranged beside igniter, monitors furnace by the temperature change of thermocouple temperature sensor
Whether light a fire inside thorax success, delivery of fuel gas always is prevented in the case where failed igniting, so as to cause the explosion of burner hearth.
The pressure in ventilation pipe is incuded by pressure sensor, and then changes the unlatching ratio of proportional control valve, is prevented
Ventilation pipe and pressure in the burner hearth difference are larger to set off an explosion.Concentration sensor on ventilation pipe is used to detect the dense of CO in pipeline
Degree prevents from continuing to be passed through combustion gas into burner hearth in the case where CO concentration is inadequate, influences the heating in burner hearth.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of the utility model roaster.
Specific embodiment
As shown in figs. 1-2, a kind of carbon baking furnace of automatic control, including burner hearth 1, the top of burner hearth 1 are provided with logical
Feed channel 3, what is led in ventilation pipe 3 is combustion gas, proportional control valve 4 is provided on ventilation pipe 3, one end of ventilation pipe 3 is stretched
Enter inside burner hearth 1, the other end of ventilation pipe 3 is connected to air-introduced machine 7, and air-introduced machine 7 is connected to gas producer 8,1 internal ventilation of burner hearth
3 exit of pipeline is provided with igniter 2, and 2 adjacent position of igniter is provided with thermocouple temperature sensor 5, and electric thermo-couple temperature passes
The end of sensor 5 reaches the front of igniter 2, and temperature sensor 6 is provided in burner hearth 1, and temperature sensor 6 is used to incude burner hearth
Bulk temperature in 1.
Concentration sensor 9 and pressure sensor 10 are provided on ventilation pipe 3, concentration sensor 9 is used to detect snorkel
The concentration of CO in road 3 closes proportional control valve, pressure after concentration sensor detects the concentration of CO lower than setting concentration
Sensor is used to detect the pressure in ventilation pipe 3.
Carbon baking furnace is provided with PLC controller, igniter 2, thermocouple temperature sensor 5, proportional control valve 4, air inducing
Machine 7, temperature sensor 6, concentration sensor 9 and pressure sensor 10 are connect with PLC controller.
The working principle of the invention is: needing to control heating rate when calcining carbon product in roaster, makes in the present invention
The autoignition temperature of combustion gas is 600 DEG C or so, and temperature inductor incudes the temperature in burner hearth, and temperature inductor is by the temperature of induction
Degree value is transferred to PLC controller, and PLC controller judges temperature value, when temperature is less than 600 DEG C in burner hearth, PLC
Controller controls proportional control valve and opens by fuel gas transmission into burner hearth, initial igniter igniting, when temperature is greater than 600 in burner hearth
DEG C when, due to having exceeded the autoignition temperature of combustion gas, do not need to light a fire again, thermocouple temperature sensor is for monitoring whether a little
Igneous function, thermocouple temperature sensor protrudes into the flame envelope below igniter close to flame, if lighted a fire successfully, electric thermo-couple temperature is passed
The temperature that sensor measures can have a greater change, and with this to determine whether lighting a fire successfully, prevent in successful situation of not lighting a fire
Always delivery of fuel gas and lead to furnace explosion, after lighting a fire successfully, heat up according to the temperature curve of setting.
Detect the pressure in ventilation shaft 3 by pressure sensor 10, PLC controller according to the pressure data being collected into,
Change proportional control valve 4 unlatching ratio, prevent ventilation shaft 3 and the pressure difference in burner hearth it is larger cause be tempered in turn cause it is quick-fried
Fried, when the pressure in pipeline is less than or equal to 0.1MPa, the pressure in ventilation pipe 3 is smaller, larger with the pressure difference in burner hearth,
Cause to be tempered, the proportional control valve 4 of PLC controller control at this time completely closes；When the pressure in pipeline is 0.1~0.2MPa,
The maximum ratio that proportional control valve 4 can be opened is 50%；When the pressure in pipeline is greater than 0.2MPa, proportional control valve 4 can
The maximum ratio of unlatching is 100%, and the controlling value of manifold pressure is specifically set according to the actual situation.
Above-described is only preferred embodiments of the present invention, it is noted that for those skilled in the art
For, under the premise of not departing from the utility model general idea, several changes and improvements can also be made, these also should be considered as
The protection scope of the utility model.
