Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0025] Embodiment 1

[0026] Please refer to Figures 1-8 , a kind of methanol fuel electric vaporization combustor in the figure, including setting in mounting bracket 103 combustor, combustor is composed of mixing cavity 101 and the combustion tube 102 setting in one side of mixing cavity 101, still include setting in one side of mounting bracket 103 for providing atomized combustion oil circuit atomizing oil pump 2 and provide gasification combustion oil circuit vaporizing oil pump 3, mounting bracket 103 is provided with fan 12 away from oil pump side, mounting bracket 103 is provided with electrical control cabinet 4 for controlling the work of combustor, mixing cavity 101 is provided with air inlet pipe 5 close to one side of mounting bracket 103, air inlet pipe 5 is provided with filter assembly for alternately filtering external dust;

[0027] The filtering assembly comprises a fixed ring 601 fixedly connected to the air inlet pipe 5 away from the mixing cavity 101, the fixed ring 601 is connected with a plurality of sector frames 603 through a rotating shaft, each sector frame 603 is connected with a sector filter plate 604 through a mounting assembly, the side of the fixed ring 601 close to the air inlet pipe 5 is provided with a motor 606, the output end of the motor 606 is connected with the rotating shaft, the side of the fixed ring 601 away from the air inlet pipe 5 is fixedly connected with a connecting pipe 605, and the fixed ring 601 is provided with an operating assembly for mounting and replacing each sector filter plate 604;

[0028] It should be noted that: through the setting of the filtering assembly, the cleanliness of the gas entering the mixing cavity 101 is ensured, and through the alternating use of the sector filter plates 604, the change of the air inlet amount in the mixing cavity 101 caused by the dust and impurities attached to the surface of the sector filter plates 604 is reduced, thereby further ensuring the sufficiency of methanol combustion, and further improving the use effect of the methanol fuel electric vaporization burner.

[0029] It should be noted that: as prior art, the specific structure and working principle of the methanol fuel electric vaporization burner have been mastered by those skilled in the art, and will not be described in detail here.

[0030] Please refer to Figure 4 , the air inlet pipe 5 in the figure is provided with an air volume sensor 9;

[0031] It should be noted that:

[0032] It should be noted that: the model of the air volume sensor 9 is a hot air speed sensor of sn20, a hot wire tungsten wire or a platinum wire or a hot film platinum or chromium film is used as a probe, which is exposed to the measured air and connected to a Wheatstone bridge. When the wind blows, the hot wire or hot film will be cooled, and its resistance value will change. The change of the resistance value is measured by the Wheatstone bridge, and then the flow rate of the measured cross section air is detected, and the air volume is obtained according to the cross-sectional area. Because the heat release coefficient is related to the air flow rate, the greater the flow rate, the greater the corresponding heat release coefficient, that is, the faster the heat dissipation; the smaller the flow rate, the slower the heat dissipation.

[0033] Working principle: when the methanol fuel electric vaporization burner is in use, first start the atomizing oil pump 2 that provides the atomizing combustion oil path, the atomized methanol is easier to be ignited, and a stable flame can be quickly established. When the start signal is sent, under the control of the electrical control cabinet 4, the atomizing oil pump 2 delivers the methanol to the atomizing nozzle at a certain pressure, and the methanol is sprayed into the combustion chamber after being atomized. At this time, the atomized methanol is ignited by the ignition device such as an electric spark igniter to form an initial flame. During the combustion of the atomized methanol, the fan 12 is used to draw a large amount of air from the outside into the combustion chamber to mix with the atomized methanol and enhance the sufficiency of the atomized methanol combustion. The vaporization oil pump 3 for providing the gasification combustion oil path can be started later, because gasification combustion needs a certain time to fully vaporize the methanol, and the vaporized methanol can burn better after the stable initial flame is formed in the combustion chamber. After the initial flame is formed, the vaporization oil pump 3 starts to work, delivers the methanol to the vaporization device for vaporization treatment, and then delivers the vaporized methanol to the combustion chamber for combustion. After the burner enters the stable combustion stage, the two oil pumps work simultaneously. They cooperate with each other to maintain the combustion process. The atomizing combustion can provide instant flame, so that the burner can maintain the combustion state under various working conditions. The gasification combustion can provide more sufficient and efficient combustion, because the mixture of vaporized methanol and air is more uniform, the combustion is more complete, the combustion efficiency is improved, and the pollutant emission is reduced.

[0034] At the same time, in the process of continuously delivering the outside air to the mixing cavity 101 by the fan 12, the dust and other impurities in the outside air are filtered by the fan-shaped filter plate 604, thereby ensuring the cleanliness of the gas entering the mixing cavity 101. When the air volume sensor 9 detects that the air inlet volume decreases after the fan-shaped filter plate 604 has filtered the outside air for a period of time, it can be judged that the fan-shaped filter plate 604 is blocked by the attachment of dust and other impurities on its surface. At this time, the motor 606 is started to drive the rotation of the fan-shaped frame 603 on the rotating shaft, thereby driving the rotation of the fan-shaped filter plate 604, so as to rotate the dirty fan-shaped filter plate 604 to the side away from the air inlet pipe 5, and rotate the clean fan-shaped filter plate 604 to the lower side of the air inlet pipe 5. Through the alternate use of the fan-shaped filter plate 604, the filtration of the outside air is realized while reducing the change of the air inlet volume in the mixing cavity 101 caused by the attachment of dust and other impurities on the surface of the fan-shaped filter plate 604, thereby further ensuring the sufficiency of the methanol combustion and improving the use effect of the methanol fuel electric vaporization burner.

The fan-shaped filter plate 604 is provided with mounting holes 704 in the different sides. Each mounting hole 704 is arranged in matching with the mounting plate 702.

[0037] It should be noted that the mounting assembly is arranged to improve the convenience of dismounting the fan-shaped filter plate 604 while mounting and fixing the fan-shaped filter plate 604, thereby facilitating the cleaning or replacement of the dirty fan-shaped filter plate 604.

[0038] Referring to Figure 7 The extrusion assembly in the drawing includes an extrusion plate 801 slidably connected with the fixing hole 701. One side of the mounting plate 702 is connected with the extrusion plate 801. Two springs 802 are fixedly connected with the bottom wall of the fixing hole 701. The other ends of the two springs 802 are connected with the extrusion plate 801.

[0039] It should be noted that the extrusion assembly is arranged to provide the guiding and resetting functions for the mounting plate 702.

The second connecting plate 1005 is connected with the two first connecting plates 1003 through a rotating rod 1004. One end of the second connecting plate 1005 is connected with the fixed ring 601. The side of the fan-shaped plate 1002 close to the fan-shaped operation hole 1001 is provided with a soft magnetic strip.

[0041] It should be noted that the operation assembly is arranged to provide the operation space for the mounting and replacement of the fan-shaped filter plate 604.

[0042] Working principle: when the fan-shaped filter plate 604 needs to be mounted and replaced, the fan-shaped plate 1002 is first opened, and then the fan-shaped filter plate 604 is pulled. Under the action of the pulling force, the fan-shaped filter plate 604 can be taken out of the fan-shaped frame 603. After the dirty fan-shaped filter plate 604 is dismounted, it can be cleaned or replaced.

[0043] After the cleaning and replacement of the sector filter plate 604 are completed, by aligning the sector filter plate 604 with the sector frame 603, and then pushing the sector filter plate 604 into the sector frame 603, when the sector filter plate 604 abuts against the mounting plate 702, under the interaction force of the inclined surface 703 and the guiding action of the extrusion assembly, the mounting plate 702 will be pushed to shrink into the fixed hole 701, with the continuous pushing of the sector filter plate 604, when the mounting plate 702 abuts against the fixed hole 701, under the elastic action of the extrusion assembly, the mounting plate 702 will be pushed to insert into the fixed hole 701 and abut against the bottom wall of the fixed hole 701, so as to realize the installation and fixation of the sector filter plate 604 by the abutting action of the mounting plate 702.
