[0030] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0031] like Figure 1-Figure 4 As shown, the present embodiment provides a fuel burner for ceramic production, including an outer wind cylinder 10, an inner wind cylinder 20 and an atomizing oil gun 21. It should be noted that the atomizing oil gun 21 is a conventional atomizing oil gun, which will not be described in detail herein. The inner wind cylinder 20 is coaxially arranged with the outer wind cylinder 10, and the inner wind cylinder 20 is arranged inside the outer wind cylinder 10. One end of the outer wind cylinder 10 has a flame outlet 22, and the port at the other end of the outer wind cylinder 10 is fixedly covered with an end cover 23. One end of the inner wind cylinder 20 is fixedly connected to the side of the end cover 23 facing the flame outlet 22, and the other end of the inner wind cylinder 20 is located in the inner cavity of the outer wind cylinder 10.

[0032] An outer sliding sleeve of the inner wind tube 20 is provided with an inner fire mesh tube 24 which is coaxially arranged with the inner wind tube 20, the inner wind tube 20 is inserted in the inner fire mesh tube 24, and one end of the inner wind tube 20 located in the inner cavity of the outer wind tube 10 is located in the inner fire mesh tube 24, the inner side wall of the outer wind tube 10 and the outer side wall of the inner fire mesh tube 24 form a combustion-supporting air ventilation duct 37, and the side wall of the outer wind tube 10 is provided with a first air duct 38 connected to the combustion-supporting air ventilation duct 37 at a position close to the end thereof connected to the end cover 23, the position of the inner wind tube 20 at one end of the inner cavity of the outer wind tube 10 corresponds to the position where the first air duct 38 is connected to the outer wind tube 10, a blower (not shown in the figure) with the air outlet direction facing the outer wind tube 10 is provided in the first air duct 38, and the inner fire mesh tube 24 has a plurality of inner cavities and combustion-supporting air ducts of the inner fire mesh tube 24. The radial through hole 26 is connected to the ventilation duct 37, and one end of the atomizing oil gun 21 has an oil outlet pipe, which passes through the end cover 23 and is connected to the inner cavity of the inner wind tube 20. The end cover 23 is provided with an adjusting component for moving the inner fire net tube 24 relative to the flamethrower 22. When the fire net tube 24 is relatively close to the flamethrower, the fuel mist is confined in the inner fire net tube 24, so that the fuel mist can burn in a smaller space and produce a more concentrated flame, that is, the flame is relatively slender. When the fire net tube 24 is relatively far away from the flamethrower, the fuel mist diffuses to the outside of the inner fire net tube 24, so that the fuel mist burns in a larger space and produces a more diffuse flame, that is, the flame is relatively thick and short. By setting the adjusting component to adjust the position of the inner fire net tube 24 relative to the flamethrower 22, the change of the flame shape can be controlled.

[0033] The adjustment assembly includes a sleeve 29 fixedly inserted into the end cover 23, a moving rod 30 slidably connected in the sleeve 29, a threaded hole (not shown in the figure) opened on the outer peripheral wall of the sleeve 29, and a bolt 31 screwed into the threaded hole. One end of the moving rod 30 is located in the inner cavity of the outer wind tube 10, and the other end of the moving rod 30 is located outside the end cover 23. One end of the moving rod 20 located in the inner cavity of the outer wind tube 10 is fixedly connected to the outer peripheral surface of the inner fire net tube 24. When it is necessary to adjust the relative position of the inner wind tube 20 and the inner fire net tube 24, loosen the bolts 31, move the moving rod 30, and finally tighten the bolts 31 so that the bolts 31 are pressed against the moving rod 20 to complete the fixation.

[0034] A swirl disk 25 is fixedly connected to the inner side wall of the inner wind cylinder 20, and the swirl disk 25 divides the inner wind cylinder 20 into a first cavity and a second cavity. The first cavity is arranged away from the flame nozzle 22 relative to the second cavity, and the second cavity is communicated with the inner cavity of the inner fire net tube 24. The atomizing oil gun 21 passes through the end cover 23 and the swirl disk 25 in sequence and then communicates with the second cavity. A first through hole 32 for the atomizing oil gun 21 to pass through is provided on the swirl disk 25, and a tangential groove 33 is also provided on the outer peripheral wall of the swirl disk 25. The depth direction of each tangential groove 33 is consistent with the radial direction of the swirl disk 25, and each tangential groove 33 runs through the swirl disk 25. The notch of each tangential groove 25 is arranged in a direction away from the axis of the swirl disk 25, and each tangential groove 33 is distributed around the axis of the swirl disk 25, and the connecting line between the two ends of each tangential groove 33 is respectively inclined to the axis of the swirl disk 25.

[0035] The second air duct 34 is also included. One end of the second air duct 34 passes through the end cover 23 and is connected to the first cavity. The other end of the second air duct 34 is connected to the first air duct 38. The second air duct 34 is provided with a first valve 35 for controlling the switch. The second air duct 34 is provided with a second valve 36 for controlling the wind speed. The switch of the second air duct 34 is controlled by the first valve 35, and the flow rate of the second air duct 34 is controlled by the second valve 36, so that the wind in the second air duct 34 passes through the tangential groove 33 to form a more obvious swirl effect, so as to change the diffusion shape of the oil mist. At the same time, by adjusting the flame shape, the combustion can be made more complete and the combustion efficiency can be improved.

[0036] A damper assembly is provided on the first air duct 38, and the damper assembly is a conventional damper assembly. In the present embodiment, the damper assembly includes a rotating shaft, a damper body and a lever. The rotating shaft is rotatably connected to the first air duct 38, and both ends of the rotating shaft pass through the first air duct 38. The damper body is located in the first air duct and is fixedly sleeved on the rotating shaft. The lever is located outside the first air duct 38 and is fixedly sleeved on the rotating shaft. By toggling the lever to drive the rotating shaft to rotate, the rotation of the rotating shaft drives the damper body to rotate, so that the opening and closing of the first air duct 38 can be controlled. The blower is located on the side of the damper body away from the outer wind tube 10, and the connection position between the first air duct 38 and the second air duct 34 is located between the damper body and the blower.

[0037] There are multiple adjustment components, each of which is distributed around the axis of the end cover 23, and each moving rod 30 is arranged parallel to the axis of the outer wind tube 10. This arrangement facilitates the adjustment of the moving rod 30 and makes the moving rod 30 move more smoothly.

[0038] Each movable rod 30 is provided with scale lines along its length direction, and the scale lines are length scale lines, which can more accurately adjust the relative positions of the inner air cylinder 20 and the inner fire net cylinder 24.

[0039] Before use, point the flamethrower of a fuel burner for ceramic production provided in this embodiment toward the ceramic kiln. When in use, use an igniter to ignite at the position of the flamethrower 22. It should be noted that the igniter is not a part of the fuel burner for ceramic production provided in this embodiment, and needs to be configured separately when in use. Part of the air in the first air duct 38 is pushed by the blower to flow into the combustion-supporting air duct 37, and the other part flows into the first cavity and the second cavity in turn through the second air duct 34, and then contacts and mixes with the fuel mist atomized and sprayed out of the oil outlet. The relative position of the end of the inner air tube 20 located in the inner cavity of the outer air tube 10 and the end of the inner fire net tube 24 away from the end cover 23 can be adjusted according to actual needs, so as to adjust the flame shape, make the combustion more complete, and improve the combustion efficiency. The utility model adjusts the position of the inner fire net tube 24 relative to the flamethrower 22 by setting an adjustment component to achieve the change of the flame shape, so that it can meet the use requirements of the ceramic kiln in different time periods, is not restricted, and has good adaptability. At the same time, by adjusting the flame shape, the combustion can be made more complete and the combustion efficiency can be improved.
