Abstract
The utility model relates to a self-pressurizing type liquid fuel gasifying range. An annular-cavity-shaped combustion head which is provided with a combustion hole is sheathed on the outside of a gasifying chamber. A gasifying preheating and ignition pipe which is provided with a combustion hole is arranged on the lower part of the combustion head, and communicated with the combustion head in the radial direction. Refractory filler with gaps is arranged on the middle part of the gasifying chamber, a gas inlet pipe is arranged between the upper part space of the gasifying chamber and the combustion head, and an oil inlet pipe and a pressurizing oil return pipe, which are communicated with the bottom of a fuel tank and the upper part space, are respectively arranged in the lower part space. An ignition tray is arranged under the combustion head and the gasifying preheating and ignition pipe, and an oil release pipe opening which is connected with the fuel tank is arranged at the appropriate position above the ignition tray.
Description
The utility model relates to a kind of gasification kitchen range that use liquid fuel.
Common liquid fuel gasification oven tool is provided with the heating arrangement of preheating gasification usefulness under combustion head, burnt by the burner port ejection of combustion head in the liquid fuel heat gasification back that enters.Because the gas pressure that obtains by gasification can be too not high merely, therefore the temperature of burning is affected.In order to increase air pressure, have manual pressure structures such as air pump, inflator are set in the fuel carrying path to obtain higher ignition temperature.This makes complex structure on the one hand, and is also not too convenient in the use.
The purpose of this utility model is to provide a kind of liquid fuel gasification oven tool that has from function of increasing pressure for addressing the above problem.
The structure of the utility model auto-pressurizing liquid fuel gasification oven tool is, is equipped with the ring cavity shape combustion head that end face has burner port outside vaporizer, and its below is provided with the gasification preheating ignition tube of radial communication, and the top of pipe has burner port.The middle part of vaporizer is filled with and keeps apertured refractory filler, as metal fillings, pottery grain etc.Be provided with the gas inlet pipe of band control valve on the vaporizer between end spaces and combustion head, following end spaces is provided with supercharging oil return pipe that is communicated with the fuel tank upper space respectively and the oil inlet pipe that is communicated with fuel tank bottom.Be provided with flashpan under combustion head and the gasification preheating ignition tube, and have the drain line that links to each other with fuel tank to be opened on appropriate location, flashpan top.During use, small amount of fuel is lighted in drain line is put in flashpan, and close the control valve of gas inlet pipe.The fire of flashpan is with the liquid fuel heat and the gasification of vaporizer bottom, and combustion gas is passed vaporizer middle part filler and risen to upper space.Because control valve cuts out, vaporising fuel can't enter combustion head, so the vaporizer internal pressure increases, impels the liquid fuel of its part to return fuel tank through the supercharging oil return pipe.So circulation, reach to fuel tank from the supercharging purpose.Because the igniter fuel in the flashpan is limited, thus pressure to increase degree limited, can not cause danger.Open the gas inlet pipe control valve, vaporising fuel enters combustion head, and a part is from top burner port ejection burning, and another part enters its below gasification preheating ignition tube by burner port ejection also burning simultaneously, continues the vaporizer lower heating is made liquid fuel gasification.The filler at vaporizer middle part can produce suitable resistance to gasification, helps to improve from pressurization.Control valve leaves greatly more, and the vaporising fuel that enters in the combustion head is many more, and combustion flame is big more; It is also big more that the gasification of preheating ignition tube of gasifying simultaneously adds thermal-flame, gasification in the vaporizer is accelerated, can increase the fuel gasification amount on the one hand, also improved simultaneously the backflow oil mass that is used for from supercharging, pressure in the fuel tank increases simultaneously, can provide more fuel and bigger pressure to enter vaporizer.When stopping using, close control valve, no fuel enters combustion head, the fray-out of flame of gasification preheating ignition tube, and the vaporizer temperature reduces, and pressure reduces, and returns to original state.
This shows that the utility model kitchen range have not only been realized the purpose from supercharging raising ignition temperature in the combustion process by the supercharging oil return pipe that is provided with, but also can finish the purpose of regulating required degree of boost voluntarily with the operation of regulating the fire amount.
Below further specify structure of the present utility model, but scope of the present utility model is not limited only to this example with example shown in the drawings.
The structural representation of Fig. 1 the utility model kitchen range
As shown in the figure, these kitchen range are equipped with the ring cavity shape combustion head 1 that a top is provided with burner port 13 outside ring cavity shape vaporizer 2, and its below is provided with the gasification preheating ignition tube 4 of radial communication, and the top of pipe has burner port 14.The middle part of vaporizer 2 is filled with and keeps apertured metal fillings filler 3, upper space and combustion head 1 sidepiece are communicated with the gas inlet pipe 6 of band control valve 7, the export department that this air inlet pipe connects with combustion head 1 is the tapering type of bore convergent, and along the tangential direction setting of combustion head, to increase intake velocity, help abundant burning, and reduce intake resistance, also can enlarge the fuel scope of application.The bottom of vaporizer 2 is provided with supercharging oil return pipe 8 and oil inlet pipe 9, is communicated with the upper space and the bottom of fuel tank 11 respectively.Be provided with a flashpan 5 under combustion head and the gasification preheating ignition tube, and have one to be communicated with the appropriate position that the drain line 10 of being with valve 12 is opened on flashpan 5 tops with fuel tank 11.
