Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of heating burner ignition control device of the utility model.
Fig. 2 is a kind of structural schematic diagram of heating burner ignition control device of the utility model.
Specific embodiment
The purpose of this utility model, advantage and feature will carry out figure by the non-limitative illustration of preferred embodiment below
Show and explains.These embodiments are only the prominent examples using technical solutions of the utility model, all to take equivalent replacement or wait
Effect transformation and formed technical solution, all fall within the requires of the utility model protection within the scope of.
The utility model discloses a kind of heating burner ignition control device, as depicted in figs. 1 and 2, the heating burner point
Fiery control device, including gas heating furnace and the burner being arranged at the top of it, the burner and natural gas supply system and
The connection of oxygen feed system, the burner are connected to ignition transformer, and the ignition transformer passes through first contactor and burner
Controller is electrically connected.
The burner is connected to electromagnetic valve for natural gas, and a delay relay is equipped on the driving circuit of electromagnetic valve for natural gas
Device, time-delay relay are connected to by the second air switch with burner controller, specifically, in the technical scheme, the delay
The front end of electromagnetic valve for natural gas is arranged in relay.The second pressure switch is arranged in parallel with time-delay relay, the delay
The input voltage of relay is alternating current 220V.
The oxygen feed system include the first air pressure switch of oxygen conveying pipe and gap setting on it and
AIR Proportional motor, the burner is connected to by AIR Proportional motor with the first air pressure switch, in the pipe of oxygen conveying pipe
Radius is 50mm.Temperature controller, the temperature control are provided between first air pressure switch and burner controller
When device gets the temperature in the gas heating furnace lower than a certain threshold value, sending heating signal is described to burner controller
Temperature controller provides heating signal when being lower than 7 degree of set temperature, stop heating after reaching set temperature.
The oxygen feed system is connected to cooling air-flow feed system, and the gas heating furnace goes out at Gas chimney also
It is provided with exhaust fan, the exhaust fan and the cooling air-flow feed system are electrically connected linkage work.The exhaust fan is set
The exclusion that can accelerate hot gas in gas heating furnace is set, the temperature in gas heating furnace is reduced, avoids in gas heating furnace
