Description

Technical Field

[0001] This utility model relates to the field of furnace head technology, and in particular to a low-voltage dual-oil-circuit thermal circulation gasification furnace head. Background Technology

[0002] Existing gasification burners are generally 220V high-pressure, high-temperature atomizing gasification burners. They preheat the burner head for 5-10 minutes using a 220V preheating coil, reaching a temperature of 90-180℃. Then, a high-power oil pump supplies fuel through a 1.2mm atomizing nozzle, atomizing the fuel. A 220V high-pressure igniter ignites the atomized fuel using a ceramic ignition needle, resulting in high-temperature gasification and combustion. The 220V high-pressure, high-temperature atomizing gasification burner head consists of a cast iron inner liner, cast iron flame cap, ceramic ignition needle, 1.2mm atomizing nozzle, 220V heating coil, 25KV igniter, 220V blower, and 220V vegetable oil combustion controller.

[0003] However, existing 220V high-pressure high-temperature atomizing gasification burners are not ideal. Firstly, the high voltage required to power the entire system poses a risk of electric shock. Secondly, the burner head requires preheating to reach its rated operating temperature and then, in conjunction with the fuel injector atomization, high-voltage spark ignition for combustion. Finally, the gasification burner head is too large, and the heavy furnace requires more energy and fuel to operate normally. The disadvantages exposed in this process are: 1. The risk of electric shock to users due to high voltage; 2. The need for more time and excessive energy consumption for preheating; 3. The excessive fuel consumption during fuel atomization; 4. Carbon buildup and blockage of the atomizing fuel injector, making it difficult to ignite and preventing normal operation. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] See attached document Figure 1 A low-voltage dual-oil-circuit thermal circulation gasification furnace head includes a furnace body structure, an oil supply mechanism, a blower mechanism, and a control mechanism. The oil supply mechanism and the blower mechanism are connected to the furnace body structure. The furnace body structure, the oil supply mechanism, and the blower mechanism are all electrically connected to the control mechanism.

[0024] The furnace body mechanism includes an outer furnace shell 1 and an inner furnace shell 2. The inner furnace shell 2 is disposed inside the outer furnace shell 1. The top surface of the inner furnace shell 2 extends horizontally outward and is fixedly connected to the inner wall of the outer furnace shell 1. Ceramic cotton 3 is installed on the bottom surface of the inner cavity of the inner furnace shell 2, and an ignition plug 4 is inserted inside the ceramic cotton 3. Several ignition needles 5 are horizontally inserted through the side wall of the inner furnace shell 2, and the ignition needles 5 extend directly above the ceramic cotton 3. The ignition plug 4 and the ignition needles 5 are electrically connected to the control mechanism.

[0025] The oil supply mechanism includes an oil pump assembly and an oil guide assembly. The oil guide assembly includes a first oil pipe 9 and a second oil pipe 10. The oil outlet end of the first oil pipe 9 extends directly above the ceramic cotton 3 and is located above the ignition needle 5. The oil outlet end of the second oil pipe 10 extends directly above the ceramic cotton 3 and is connected to a vaporizing head 11. The vaporizing head 11 is limited above the first oil pipe 9.

[0026] The blower mechanism penetrates the bottom surface of the furnace shell 1 from the outside to the inside and communicates with the inner cavity of the furnace shell 1. Several air inlets 12 are provided on the side wall of the inner shell 2 of the furnace.

[0027] Both the outer shell 1 and the inner shell 2 of the furnace body are vertically arranged cylindrical structures, which can be square or cylindrical. The axes of the outer shell 1 and the inner shell 2 of the furnace body coincide. There are gaps between the side walls and bottom surface of the inner shell 2 and the side walls and bottom surface of the outer shell 1 of the furnace body. The minimum number of ignition needles 5 is two, which can be used as two electrodes to generate electric sparks. The ignition needles 5 are set close to the ceramic cotton 3 for easier ignition. The control mechanism can control the discharge of the ignition needles 5.

[0028] The first oil pipe 9 and the second oil pipe 10 both penetrate from the bottom surface of the outer shell 1 into the gap between the outer shell 1 and the inner shell 2, and then extend from the outside to the inside through the side wall of the inner shell 2 into the inner cavity of the inner shell 2; the oil flowing out from the first oil pipe 9 and the second oil pipe 10 needs to be able to drip onto the ceramic cotton 3; the vaporization head 11 can vaporize the oil, making the combustion more complete and the flame more stable.

[0029] The blower mechanism can blow outside air into the gap between the outer shell 1 and the inner shell 2 of the furnace body, and finally into the inner cavity of the inner shell 2 of the furnace body through the air inlet 12 to provide oxygen for combustion.

[0030] Further optimization of the scheme: the oil pump assembly includes an oil pump 6, the oil pump 6 has an oil tank 7 connected to its inlet end and a three-way valve 8 connected to its outlet end; the first oil pipe 9 and the second oil pipe 10 are both connected to the three-way valve 8.

[0031] The three ports of the three-way valve 8 are connected to the oil outlet of the oil pump 6, the first oil pipe 9, and the second oil pipe 10, respectively. The oil pump 6 can draw oil out of the oil tank 7 and send it into the first oil pipe 9 and the second oil pipe 10, and finally flow out from the top of the ceramic cotton 3.

[0032] Further optimization of the design: the blower mechanism includes a blower 13, the air outlet of the blower 13 is connected to an air duct 14, and the end of the air duct 14 away from the blower 13 passes through the bottom surface of the furnace shell 1 from the outside to the inside and is connected to the inner cavity of the furnace shell 1.

[0033] The blower 13 can supply air into the furnace to provide sufficient oxygen for combustion inside the furnace. The blower 13 draws air into the air duct 14, and then the airflow in the air duct 14 enters the furnace shell 1, and finally enters the furnace inner shell 2 through the air inlet 12.

[0034] The scheme is further optimized. The control mechanism includes a first controller 15 and a second controller 16. The fan 13, oil pump 6, ignition needle 5, and ignition plug 4 are all electrically connected to the second controller 16, and the first controller 15 and the second controller 16 are electrically connected.

[0035] The first controller 15 and the second controller 16 use low voltages that are below the human body safety voltage standard. The first controller 15 can control the second controller 16 to issue corresponding commands. The second controller 16 can also control the operation of the fan 13, oil pump 6, ignition needle 5, and ignition plug 4.

[0036] To further optimize the design, one-way valves 17 are installed on both the first oil pipe 9 and the second oil pipe 10.

[0037] One-way valve 17 can make the oil supply more stable, economical, efficient and smooth.

[0038] The working principle is as follows: When the power is turned on and the first controller 15 is turned on, the second controller 16 will also start working, causing the oil pump 6, blower 13, ignition plug 4, and ignition needle 5 to work simultaneously. The oil pump 6 supplies fuel to the top of the first oil pipe 9 and the second oil pipe 10, and the fuel drips onto the ceramic cotton 3 below. At this time, the ignition plug 4 located below the ceramic cotton 3 encounters the fuel and vaporizes it. The ignition needle 5 then ignites the fuel vapor, causing it to burn on the ceramic cotton 3. The combustion temperature is transferred to the vaporization head 11 located at the top of the second oil pipe 10, so that the flame continues and fully vaporizes and burns.

[0039] The dual oil circuit design of this invention, with the addition of a one-way valve, makes the small fire more stable and the large fire more intense. In addition, the invention features a specially designed gasification head that passes through the furnace body via an oil pipe, which can maintain an excellent gasification temperature to ensure complete combustion of fuel and achieve a heat circulation effect.

[0040] This utility model provides a dual-oil-circuit thermal circulation gasification burner. Firstly, it operates at a voltage lower than the human safety standard. This significantly improves upon previous 220V high-pressure, high-temperature atomization gasification combustion burners by offering two advantages: firstly, safety, eliminating the risk of electric shock; and secondly, economy, as low voltage means low energy consumption. This dual-oil-circuit thermal circulation gasification burner requires only the simultaneous operation of the ignition plug hidden under the ceramic cotton at the bottom of the furnace, the ignition needle located on the furnace wall, and the oil pump. A special gasification device at the top of the oil pipe ensures more complete combustion and a more stable flame. Compared to the previous 220V high-pressure high-temperature atomizing gasification burner, firstly, this device eliminates the atomization stage, avoiding the need for high-pressure fuel injectors and preventing fuel injector carbon buildup, blockage, and damage; secondly, this device does not require the burner to reach a stable high temperature before normal combustion. The 220V high-pressure high-temperature atomizing gasification burner requires a high-power heating coil to bring the burner to operating temperature before a high-pressure oil pump atomizes the fuel through high-pressure fuel injectors, which then atomizes the fuel upon contact with the preheated high-temperature burner before ignition by a high-pressure ignition needle – a process that takes 5-10 minutes. In comparison, this device is superior in terms of energy consumption, consumables, and time. Therefore, the dual-oil-path thermal circulation gasification burner provided by this invention is safer, lighter, more convenient, more economical, energy-efficient, and more stable!
