Description
Technical Field
The utility model relates to a baking device, in particular to an igniter of a hot blast stove.
Background
The existing biomass fuel hot blast stove has wide application. The heat source is widely used for the baking room of agricultural products such as tobacco leaves, vegetables and the like. The working principle is as follows: biomass fuel is combusted in a hearth of the hot blast stove, smoke and fire are discharged through a heat exchange pipe of the heat exchanger, wind outside the heat exchange pipe generates hot wind, and the hot wind is conveyed to a baking room to provide heat for baking.
The biomass fuel needs to be added with fuel and ignited when being combusted in a hearth of the hot blast stove. And igniting the fuel is the first step.
At present, the common method for igniting fuel is to put open fire into a hearth to ignite the fuel, and the method has the disadvantages of troublesome operation, low efficiency and inconvenience for realizing automation. There are also methods of igniting fuel by electrical heating, and placing an electrical heating tube in a hearth to contact with fuel to ignite the fuel or igniting the fuel by hot air, which are convenient for automation, but all have a drawback that: the electric heating device is contacted with fuel and is in high-temperature flame for a long time, so that the electric heating device is easy to damage and has high cost.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a hot blast stove igniter with high efficiency and low cost.
In order to solve the technical problem, the igniter of the hot blast stove comprises a hot blast pipe, a fan and an ignition chamber; the ignition device is positioned at the bottom of the hot blast stove; the ignition chamber is arranged below the hearth of the hot blast stove; the bottom of the ignition chamber is closed, the side wall of the ignition chamber is provided with a vent hole, and an opening at the upper part of the ignition chamber is communicated with the hearth; an electric heater is arranged in the hot air pipe; the air inlet of the hot air pipe is connected with the fan, and the air outlet extends to the side wall of the ignition chamber.
The electric heater is an electric heating rod.
The electric heating rods are provided with 2 electric heating rods.
The air outlet of the hot air pipe is contacted with the side wall of the ignition chamber.
And the power supply control device of the electric heater is electrically connected with the power supply control device of the fan.
The power supply control device of the electric heater is provided with an electric heater power-on time control device.
The electric heater electrifying time control device is set to be electrified for 2-6 minutes.
The electric heater electrifying time control device is set to be electrified for 2 minutes.
The air outlet of the hot air pipe is conical.
By adopting the structure of the utility model, because the hot air pipe, the fan and the ignition chamber are arranged, the electric heater is arranged in the hot air pipe, the air inlet of the hot air pipe is connected with the fan, and the air outlet extends to the side wall of the ignition chamber, thus, the electric heater is heated, and hot air in the hot air pipe is blown into the ignition chamber from the side wall of the ignition chamber to ignite fuel in the ignition chamber. The device has high ignition efficiency, and the electric heating device is not contacted with high-temperature flame, is not easy to damage and has low cost.
The ignition device is specially provided with the ignition chamber, the ignition chamber is arranged below a hearth of the hot blast stove, the bottom of the ignition chamber is closed, the side wall of the ignition chamber is provided with the vent hole, and the upper opening of the ignition chamber is communicated with the hearth, so that the ignition chamber is independent from the hearth, the ignition chamber only has the function of igniting biomass fuel, the biomass fuel in the ignition chamber ignites the fuel in the hearth after being ignited, then the biomass fuel in the ignition chamber is burnt out and is not combusted, a hot blast pipe in contact with the ignition chamber can not contact with high temperature, the service life of the ignition device can be prolonged, and the cost is reduced.
The power supply control device of the electric heater is electrically connected with the power supply control device of the fan, so that the automatic operation of the hot blast stove can be realized. The power supply control device of the electric heater is provided with the electric heater electrifying time control device, and the electric heater electrifying time control device is electrified for 2-6 minutes, so that the electrifying time of the electric heater can be effectively and accurately controlled, the electric heater is electrified and heated enough to ignite biomass fuel in an ignition chamber, the electric heater cannot be wasted due to long-time electrification, the electric heater cannot be damaged, resources can be further saved, and the cost can be further reduced.
