The fuel-oil atomization mechanism is composed of a direct current motor, a fan, an oil nozzle and an oil pump arranged downwards which are orderly arranged along an axial direction. The ignition electrode of the ignition combustion mechanism is positioned at the front of the oil nozzle, and the back of the ignition electrode is connected with a cavity type combustion chamber in which a sensor for flame temperature is arranged. The water cycle heat conducting mechanism comprises a water jacket which is sheathed outside the combustion chamber and forms an air-tight drum shape, a heat exchanger, a water pump, and a water outlet pipe. The water pump and the water outlet pipe are communicated. The whole heater is assembled together. The utility model has the advantages of high combustion efficiency, fast ignition, less power consumption, and accurate temperature control. The utility model is suitable for being used by small heat supply sources, and especially mobile places, such as vehicles, etc.
Description
The utility model relates to a kind of fuel heater, especially a kind of free-standing fuel heater.
At present, the required thermal source such as hot heating and demist, defrosting, small-sized heating oven dry that gives of motor adopts fuel heater to finish on motor vehicle, the boats and ships.Yet there is major defect in the structure of existing fuel heater: the oil droplet that atomizing wheel gets rid of oil atomization is big, distribution is uneven; Electric heating wire is lighted a fire, is lighted slowly, power consumption is many, and strand is easy to blow damage; Flame temperature sensor adopts two kinds of different materials of thermal coefficient of expansion, stretches by temperature sensor and touches sensitive switch and carry out IGNITION CONTROL, response lag, poor reliability.These defectives cause that combustion thermal efficiency is poor, big energy-consuming, fault are many.
The purpose of this utility model is at the deficiency in the existing fuel heater, the adoption of innovation oil injecting nozzle, attachedly join high voltage ignition electrode and thermistor-type flame temperature sensor, cooling-water temperature sensor, thus providing a kind of has that fuel atomization effect is good, igniting is fast, the flame temperature control accurately, the little and high safe and reliable free-standing fuel heater of the thermal efficiency of power consumption.
Task of the present utility model is finished by following technical proposals:
This free-standing fuel heater, include fuel-oil atmozation mechanism, the water cycle heat-conducting mechanism of ignition mechanism and band flow guide device and electric control operation plate are formed for the formant structure, it is characterized in that: system of fuel-oil atmozation mechanism is by axially arranging the direct current generator of establishing successively, fan, the oil pump of oil injecting nozzle and underlying constitutes, before igniting polar in the ignition mechanism is positioned at oil injecting nozzle, after connect air deflector, the cavity type firing chamber, be provided with flame temperature sensor in the chamber, said water cycle heat-conducting mechanism includes to be set in and is the heat exchanger that seals tubbiness outside the firing chamber, cooling-water temperature sensor and water pump that is communicated with it and outlet pipe.
The spray angle of oil nozzle is selected in 80 °.
Flame temperature sensor system is the sensible heat element by the thermistor that is sealed in the tube-like envelope, and the termination of its thermistor protrudes in tube-like envelope and is placed in the firing chamber, and shell and thermistor insulate with porcelain tube.
Description of drawings of the present utility model:
Fig. 1 is overall structure figure of the present utility model.
Among the figure: direct current generator 1, fan 2, oil injecting nozzle 3, solenoid valve 4, igniting polar 5, water pump 6, flame temperature sensor 7, outlet pipe 8, heat exchanger 9, firing chamber 10, oil pump 11.
The utility model will elaborate with embodiment in conjunction with the accompanying drawings.
This free-standing fuel heater as shown in Figure 1, direct current generator 1 places an end, arbor attaching fan 2 is thereafter an oil injecting nozzle 3, being axially successively, order row establishes.Oil pump 11 underlyings, and form oil circuit with oil purifier, oil inlet pipe and oil overflow pipe wholely constitute fuel-oil atmozation mechanism.Between oil injecting nozzle 3 and fan 2, be provided with the solenoid valve 4 of control fuel delivery, the eruption mist of oil angle of oil injecting nozzle 3 is at 80 °, igniting polar 5 discharges the pole piece of high-tension current percussion spark ignition mist of oil and is just putting between the inlet of oil injecting nozzle 3 and firing chamber 10, above 10 cavitys of firing chamber, flame temperature sensor 7 is housed, the termination of its thermistor is exposed to tube-like envelope, combines ignition mechanism.Water pump 6 in the water cycle heat-conducting mechanism is located at outside the casing at this fuel heater middle part, communicate with the heat exchanger 9 of sealing tubbiness outside being set in firing chamber 10 through intake pipe, these heat exchanger 9 tops have outlet pipe 8 to lead to use hot device, and the water cycle heat-conducting mechanism that cooling-water temperature sensor forms internal-external heat exchange is housed.Each unit mechanisms and parts are realized coordination by the circuit regulation and control of electric control operation plate and application prior art.
The free-standing fuel heater of the utility model in use, should be installed under the liquid levels with hot device such as radiator or motor, so that it is consistent with motor that cooling liquid is flowed to, guarantee as the output hot water of heating agent with exchange with hot device enforcement, to reach the heat supply purpose.What the utility model was opened running is movingly: power-on switch, water pump 6 operations are supplied water, and direct current generator 1 drives fan, fuel oil by oil pump 11 through solenoid valve 4 to oil injecting nozzle 3 fuel feeding, and with 10kg/cm
2Oil pressure pressure be 80 ° of angles eruption mist of oils to firing chamber 10.Meanwhile, igniting polar 5 output high-tension currents, the electrical spark of setting out are lighted the atomizing oil droplet, the 10 cavity internal combustion in the firing chamber, and scorching hot air-flow is passed to heat in water in the heat exchanger 9 through heat exchanger 9 by radiating fin, discharges from smoke exhaust port again.Hot water behind the heat temperature raising flows to hot device as the heating agent heat supply from outlet pipe 8, and the water behind the temperature drop can be through external pipeline water pump 6 Heating Cyclic once more of backflowing.The fuel oil flame temperature is by being exposed to the thermistor termination impression of the flame temperature sensor 7 in the firing chamber 11 in the firing chamber 10, water temperature is experienced by cooling-water temperature sensor, controls fuel-oil atmozation mechanism and ignition mechanism and the coordination of water cycle heat-conducting mechanism by circuit through the electric control operation plate.This electrical control circuit is the application of prior art, accurately and reliably.
The utility model is compared with existing fuel heater, owing to adopted fuel injection nozzle atomizing oil spout, and than atomizing wheel Get rid of that oil atomization is effective, oil droplet is tiny and be evenly distributed, efficiency of combustion obviously improves; Light a fire with high-voltage discharging electrode Substitute original heating wire igniting, not only igniting is fast, little power consumption and greatly prolonging service life; Thermistor passes Sensor temperature-sensitive acumen, accurately, sensing is fast, thereby improved serviceability.
