Description

Technical Field

[0001] The invention relates to the technical field of oil burners, in particular to an oil burner with an anti-coking function. Background Art

[0002] Oil burners are a type of combustion device that uses oil as the main fuel. Oil burners are used in various places in life, especially in industrial applications. Oil burners are usually used to provide heat to equipment to heat and dry materials.

[0003] During the combustion process of existing oil burners, the easily vaporized substances contained in the oil quickly evaporate into gaseous form and enter the flue gas. When the temperature drops, they condense or adhere to the heated surface washed by the flue gas or the nozzle of the oil burner, or condense on the surface of the fly ash particles, forming a molten alkali film, which then adheres to the heated surface to form an initial coking layer, which becomes the condition for the development of coking. When the temperature in the nozzle of the oil burner is high, some ash particles have reached a molten or semi-molten state. These ash particles have not been sufficiently cooled to reach a solidified state before diffusing to the heated surface. They have a high bonding ability and are easily adhered to the heated surface or nozzle, and even remain in a molten state, thereby forming coking. In order to prevent coking, existing oil burners spray anti-coking coatings in the nozzle of the combustion head. However, the anti-coking coatings are easily worn and fall off when used under heat for a long time, thereby affecting the anti-coking performance. For this reason, we propose an oil burner with an anti-coking function to solve the above problems. Summary of the Invention

[0022] Example 2

[0023] Reference Figure 1-5 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, the end of the connecting rod 10 away from the connecting plate 11 is coaxially fixedly connected with a threaded head, and the threaded head is connected to the rotating ring 8 through a threaded structure. The setting of the threaded structure makes it convenient to remove the connecting rod 10. After cleaning the nozzle 2, it is convenient to remove the inner wall scraper 12 and clean the inner wall scraper 12 to avoid the scraped particles from sticking to it, and to prevent coking on the inner wall scraper 12 and the folding scraper 13 in the later stage.

[0024] Specifically, an outer wall fixed sleeve on one side of the connecting rod 10 is provided with an anti-slip sleeve 9, and the anti-slip sleeve 9 is made of high-temperature resistant and heat-insulating rubber material. The anti-slip sleeve 9 increases the friction force of operating the connecting rod 10, making it convenient to disassemble the connecting rod 10.

[0025] Specifically, the inner wall scraper 12 and the folding scraper 13 have opposite end faces fixedly connected with high-temperature resistant scraping strips 14, respectively. The high-temperature resistant scraping strips 14 are isosceles triangular prism structures. When the high-temperature resistant scraping strips 14 scrape the inner wall of the nozzle 2 and the flame stabilizing disk 21, the scraped coke particles can smoothly slide down from both sides of the high-temperature resistant scraping strips 14 to avoid sticking to the high-temperature resistant scraping strips 14. The high-temperature resistant scraping strips 14 of the inner wall scraper 12 slide in contact with the inner wall of the nozzle 2.

A limiting ring 32 is movably provided in the movable cavity 34, and the limiting ring 32 is fixedly sleeved on the outside of the movable rod 31. One side of the limiting ring 32 is fixedly connected to one end of the spring 33, and the other end of the spring 33 is fixedly connected to one inner wall of the movable cavity 34. One end of the movable rod 31 is movably extended out of the connecting plate 11, and the other end is hinged to the movable connecting rod 35. The end of the movable connecting rod 35 away from the movable rod 31 is fixedly connected to the block 36, and the block 36 and the movable connecting rod 35 are rotatably arranged in the groove 121 through the rotating shaft. One side of the folding scraper 13 is fixedly connected to the hinge rod 132, which is hinged to one end of the inner wall scraper 12. The other side of the folding scraper 13 is fixedly connected to the fixed block 131, which cooperates with the block 36. When the oil burner body 1 stops working, the movable rod 31 of the limit assembly 3 is pressed, and the movable rod 31 moves, driving the fixed limit ring 32 to move. The limit ring 32 moves in the movable cavity 34, thereby compressing the spring 33 set in the movable cavity 34. The spring 33 accumulates elastic potential energy. At the same time, the movable connecting rod 35 hinged at the end of the movable rod 31 rotates with the rotating shaft in the groove 121 as the center of the circle. The movable connecting rod 35 then drives the fixed block 36 to rotate. After the block 36 rotates, it disengages from the fixed block 131.

The inner walls of the opposite sides of the oblique groove 122 and the second oblique groove 133 are respectively fixedly connected to the two ends of the strong spring 123. After the clamping block 36 and the fixed clamping block 131 are disengaged, the strong spring 123 fixedly connected in the first oblique groove 122 and the second oblique groove 133 releases its elastic potential energy, thereby driving the folding scraper 13 to rotate in a circle around the hinge point of the hinge rod 132. After the folding scraper 13 rotates toward the flame stabilizing disk 21, it drives the high-temperature resistant scraping strip 14 fixedly connected to the outer wall to contact the surface of the flame stabilizing disk 21. The folding scraper 13 then rotates synchronously with the rotation of the inner wall scraper 12, and the high-temperature resistant scraping strip 14 fixedly connected to the folding scraper 13 cleans the surface of the flame stabilizing disk 21.

After the connecting rod 10 rotates, it drives the connecting plate 11 connected at the end to rotate in a circle. The connecting plate 11 drives the inner wall scraper 12 fixedly connected at the end to rotate in a circle. The inner wall scraper 12 drives the fixedly connected high-temperature resistant scraper 14 to rotate in a circle. The high-temperature resistant scraper 14 slides in contact with the inner wall of the nozzle 2, thereby cleaning the inner wall of the nozzle 2 to prevent the gasified material from sticking to the inner wall of the nozzle 2 to form coking. The inner wall scraper 12 is made of high-temperature resistant metal to prevent the fuel burner body 1 from burning out when working. When the fuel burner body 1 stops working, the movable rod 31 of the limit assembly 3 is pressed, and the movable rod 31 moves, driving the fixed connection The limit ring 32 connected to the movable cavity 34 moves, and the limit ring 32 moves in the movable cavity 34, thereby compressing the spring 33 set in the movable cavity 34, and the spring 33 accumulates elastic potential energy. At the same time, the movable connecting rod 35 hinged at the end of the movable rod 31 rotates with the rotating shaft in the groove 121 as the center of the circle, and the movable connecting rod 35 drives the fixedly connected clamping block 36 to rotate. After the clamping block 36 rotates, it is disengaged from the clamping connection with the fixed clamping block 131. After disengaging, the strong clamping block 36 fixedly connected in the oblique groove 122 and the oblique groove 2 133 is The force spring 123 releases elastic potential energy, thereby driving the folding scraper 13 to rotate in a circle with the hinge point of the hinge rod 132 as the center. After the folding scraper 13 rotates toward the flame stabilizing disk 21, it drives the high-temperature resistant scraper strip 14 fixedly connected to the outer wall to contact the surface of the flame stabilizing disk 21. The folding scraper 13 then rotates synchronously driven by the circular rotation of the inner wall scraper 12. The high-temperature resistant scraper strip 14 fixedly connected to the folding scraper 13 cleans the surface of the flame stabilizing disk 21 to prevent the flame stabilizing disk 21 from coking.
