Description

Technical Field

[0001] The utility model relates to the technical field of burners, in particular to a dual-mode nozzle assembly of a special liquid burner. Background Art

[0002] Premixed combustion involves evaporating liquid fuel into a gas before combustion, then premixing it with air to form a combustible mixture, which is then injected into the combustion chamber for combustion. Diffusion combustion involves evaporating liquid fuel into a gas and introducing it separately from air, where it mixes and burns simultaneously. Diffusion and premixed combustion modes can be used in conjunction to improve combustion efficiency and reduce pollutant emissions. Currently, switching between these two modes typically requires two sets of injection structures, which is relatively complex. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figure 1-4The utility model provides a dual-mode nozzle assembly of a special liquid burner, comprising: a fuel evaporation chamber 1 and a mixing tube 2 arranged on one side of the fuel evaporation chamber 1, and also comprising: a connecting tube 3 connected to the fuel evaporation chamber 1 and the mixing tube 2, an air extraction pump 4 is installed on the connecting tube 3, and a two-way tube 5 is connected to the inner wall of one side of the mixing tube 2, an air jet nozzle 6 is installed at the bottom pipe mouth of the two-way tube 5, and a first box body 7 and a second box body 8 are respectively installed on the two branch pipes of the two-way tube 5, a fuel nozzle 9 is installed at the bottom of the mixing tube 2, and an adjusting assembly 10 is installed on the outer wall of the bottom of the first box body 7, a support plate 11 is installed on the inner wall of the mixing tube 2, and a mixing assembly 12 is rotatably installed on the outer wall of the top of the support plate 11, and an intermittent air intake assembly 13 is installed on the outer wall of one side of the mixing assembly 12.

[0019] It should be noted here that the fuel vapor in the fuel evaporation chamber 1 can be pumped into the mixing tube 2 by the vacuum pump 4. When the premixed combustion mode is required, air can be introduced through the two-way pipe 5. The air enters the mixing tube 2 through the first box body 7. During the process of the fuel vapor being pumped into the mixing tube 2, the mixing assembly 12 can be blown to rotate. The rotation of the mixing assembly 12 can mix the air and fuel vapor in the mixing tube 2. After mixing, it is ejected through the fuel nozzle 9 for combustion. The intermittent air intake assembly 13 can rotate together with the mixing assembly 12. During the rotation, the intermittent air intake assembly 13 can intermittently close the pipe opening connecting the two-way pipe 5 and the inner wall of one side of the mixing tube 2, so as to facilitate the quantitative intermittent air intake. When the diffusion combustion mode is required, the channel in the first box body 7 can be closed and the channel in the second box body 8 can be opened by the adjustment assembly 10. At this time, the air is ejected directly from the nozzle 6, and the fuel vapor is ejected from the fuel nozzle 9 and mixed with the air while burning. Through a set of ejection structures, the switching and coordinated use of the diffusion combustion mode and the premixed combustion mode can be realized, which is more convenient and simple.

[0020] In a preferred embodiment, the adjustment assembly 10 includes an electric push rod 1001 , a connecting plate 1002 installed at the bottom of the piston rod of the electric push rod 1001 , and a vertical plate 1003 installed on an outer wall of one side of the connecting plate 1002 .

[0021] It should be noted here that the electric push rod 1001 can drive the connecting plate 1002 and the vertical plate 1003 to rise and fall through the extension and retraction of the piston rod. When the vertical plate 1003 descends, it can open the channel in the first box body 7 and close the channel in the second box body 8. When the vertical plate 1003 rises, it can close the channel in the first box body 7 and open the channel in the second box body 8.

[0022] In a preferred embodiment, the mixing assembly 12 includes a long shaft 1201 , a fan blade 1202 installed on the top of the long shaft 1201 , and a plurality of stirring rods 1203 installed on the outer wall of the fan blade 1202 and distributed at equal distances.

[0023] It should be noted here that the fuel vapor is pumped into the mixing tube 2, which can drive the fan blades 1202 to rotate, thereby driving the long shaft 1201 and the stirring rod 1203 to rotate, making it easier to stir and mix the air and fuel vapor.

[0024] In a preferred embodiment, the intermittent air intake assembly 13 includes a fixed plate 1301 and an arcuate plate 1302 installed at one end of the fixed plate 1301 . The fixed plate 1301 is connected to the long axis 1201 , and the arcuate plate 1302 corresponds to the air inlet of the dual-channel pipe 5 .

[0025] It should be noted here that the fixed plate 1301 and the curved plate 1302 can rotate together with the stirring rod 1203. During the rotation, the curved plate 1302 can intermittently close the pipe opening connecting the double-way pipe 5 and the inner wall of one side of the mixing pipe 2, thereby facilitating the quantitative intermittent air intake.

[0026] Working principle: The electric push rod 1001 can drive the connecting plate 1002 and the vertical plate 1003 to rise and fall through the extension and contraction of the piston rod. The vertical plate 1003 descends to open the channel in the first box body 7 and close the channel in the second box body 8. The vertical plate 1003 rises to close the channel in the first box body 7 and open the channel in the second box body 8.

[0027] The fuel vapor in the fuel evaporation chamber 1 can be pumped into the mixing tube 2 by the suction pump 4. When the premixed combustion mode is required, the electric push rod 1001 can drive the vertical plate 1003 to descend, open the channel in the first box body 7, and close the channel in the second box body 8. Air can be introduced through the two-way pipe 5, and the air enters the mixing tube 2 through the first box body 7. In the process of the fuel vapor being pumped into the mixing tube 2, the fan blades 1202 can be blown to rotate, thereby driving the long shaft 1201 and the stirring rod 1203 to rotate, so as to facilitate the stirring and mixing of the air and the fuel vapor. The fixed plate 1301 and the curved plate 1302 can rotate together with the stirring rod 1203. During the rotation, the curved plate 1302 can intermittently close the pipe opening connected to the inner wall of one side of the two-way pipe 5 and the mixing tube 2, so as to facilitate the quantitative intermittent intake of air. After mixing, the air is ejected through the fuel nozzle 9 for combustion;

[0028] When the diffusion combustion mode is required, the electric push rod 1001 can drive the vertical plate 1003 to rise. The rising vertical plate 1003 can close the channel in the first box body 7 and open the channel in the second box body 8. At this time, the air is directly ejected from the nozzle 6, and the fuel vapor is ejected from the fuel nozzle 9 and burns while mixing with the air. Through a set of ejection structures, the switching and coordinated use of the diffusion combustion mode and the premixed combustion mode can be realized, which is more convenient and simple.

[0029] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
