Description

Technical Field

[0001] The utility model relates to the technical field of vegetable oil stoves, in particular to a fuel oil preheating ignition device. Background Art

[0002] The advantage of vegetable oil as a fuel is that it cannot be ignited by open flames, is not a hazardous chemical, is non-toxic, and will not cause explosive safety accidents like liquefied gas. Another advantage of vegetable oil fuel is that it saves energy. Vegetable oil fuel has a high calorific value and is more than three times more resistant to burning than methanol fuel. It can also save 30% compared to liquefied gas. However, vegetable oil is not flammable and has a high flash point. If you want to ignite vegetable oil, you need a very high voltage to ignite the vegetable oil fuel, which has certain limitations in use.

[0003] According to patent number CN214949229U, a utility model patent for a vegetable oil stove includes a stove body, the main body is provided with a burner, a furnace core is provided at the center of the burner, a heating zone is provided around the bottom of the furnace core, a heating chamber is provided at the bottom of the heating zone, a heater is provided in the heating chamber, the burner head is connected with a preheating tube, the preheating tube is connected with the furnace core through the heater, the heating tube is connected with an oil pump, the oil pump is connected with an oil inlet pipe, and an igniter is provided in the heating tube burner, so as to achieve the purpose of effectively burning vegetable oil.

[0004] When preheating vegetable oil fuel, the above technical solution first heats the preheating tube through the heater, then allows the vegetable oil to flow through the preheating tube, and then preheats the vegetable oil through heat exchange. Although the vegetable oil can be preheated, the heat exchange method will not only cause a large amount of heat loss, but also requires the heater to always maintain a high-temperature working state to heat the continuously flowing vegetable oil, causing the thermal efficiency of the vegetable oil fuel to remain unstable.

[0028] Example, see Figure 1-3 A fuel preheating ignition device comprises an oil storage barrel 1, an oil pump 13 installed on one side of the oil storage barrel 1, a refueling port 11 is downwardly opened on one side of the upper end of the oil storage barrel 1, and the refueling port 11 is detachably connected to an oil cap 12 matched therewith, the oil inlet of the oil pump 13 is connected to an oil inlet pipe 14 extending to the bottom of the inner wall of the oil storage barrel 1, and the oil outlet of the oil pump 13 is connected to an oil outlet pipe 15, and the upper end of the oil outlet pipe 15 is provided with a preheating component 16 connected to the lower front end of the outer wall, the preheating component 16 comprises a preheating box 17 with a hollow interior, a plurality of electric heaters 18 installed on the inner wall of the preheating box 17, and a spiral heat conductive wire 19 in the preheating box 17 and matched with the inner wall of the electric heater 18, and a plurality of hollow heat conductive sheets 2 are provided along the length of the inner wall of the heat conductive wire 19 in the preheating box 17.

[0029] A temperature sensor 21 is installed at the rear end of the inner wall of the preheating box 17, and a flow control valve 22 connected to the preheating box 17 is installed above the rear end of the outer wall of the preheating box 17. The rear end of the flow control valve 22 is connected to an oil guide pipe 23, and the upper end of the oil guide pipe 23 is connected to a burner nozzle 24. The diameter of the oil guide pipe 23 is smaller than the diameter of the oil outlet pipe 15. The outer wall of the preheating box 17 is wrapped with an insulation sleeve 25 that matches it. A control panel 26 is provided on the other side of the upper end of the outer wall of the oil storage barrel 1, and the electric heater 18, the temperature sensor 21, the oil pump 13 and the flow control valve 22 are all electrically connected to the control panel 26.

[0030] Usage: When in use, install the device on the stove, then open the oil cap 12 and add vegetable oil fuel into the oil storage barrel 1 through the refueling port 11. When necessary, power on the device and operate the control panel 26 to allow the electric heater 18 in the preheating component 16 to work. The heat generated by the electric heater 18 will be conducted to the heat conductive wire 19 and the heat conductive sheet 2. Then, allow the oil pump 13 to work. The oil pump 13 draws the vegetable oil into the preheating box 17 through the oil inlet pipe 14 and the oil outlet pipe 15. At this time, the electric heater 18, the heat conductive wire 19 and the heat conductive sheet 2 will preheat the vegetable oil. The temperature sensor 21 can control the heating temperature within an appropriate range to avoid the heating temperature of the vegetable oil being too high or too low. The insulation sleeve 25 can prevent the heat in the preheating box 17 from escaping, thereby keeping it warm.

[0031] Then, the control panel 26 is operated and the oil output can be controlled through the flow control valve 22. The preheated vegetable oil is transported to the burner nozzle 24 through the oil guide pipe 23 and can be used directly by igniting the stove. Since there is a height difference between the oil inlet pipe 14 and the oil outlet pipe 15 and the diameter of the oil guide pipe 23 is smaller than that of the oil outlet pipe 15, the residence time of the vegetable oil fuel in the preheating box 17 can be increased to a certain extent, thereby improving the preheating effect and allowing the vegetable oil fuel to be fully burned after being sprayed out through the burner nozzle 24.
