[0036] The technical solutions of the embodiments of this utility model are explained and described below. However, the following embodiments are only preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of this utility model.

[0037] See Figures 1 to 9 The multi-angle flame-spraying device of this utility model embodiment includes:

[0038] One shot;

[0039] Multiple nozzles, each including an air inlet and an air outlet;

[0040] Each gun head is detachably connected to the gun body;

[0041] Among them, at least some of the gun heads have different air outlet angles.

[0042] This utility model relates to a multi-angle flame-throwing device, which includes a gun body and multiple nozzles with different exhaust angles detachably connected to the gun body. Appropriate nozzles can be selected and installed as needed to meet various requirements. The size of the exhaust angle is mainly considered in relation to the circumferential angle of the workpiece (usually a pipe).

[0043] Example 1

[0044] See Figures 1 to 9 The multi-angle flame-spraying device of Embodiment 1 of this utility model includes:

[0045] One shot, 0.2;

[0046] Multiple gun heads 01, each including an air inlet 11 and an air outlet 12;

[0047] Among them, each gun head 01 is detachably connected to the gun body 02;

[0048] The air outlet 12 of each gun head 01 has a different air outlet angle.

[0049] See Figures 1 to 3 In this embodiment, the multi-angle flame-throwing device also includes a connecting air pipe 03 and an air valve 04.

[0050] In this embodiment, each gun head 01 includes the same air inlet 11, and the air inlet 11 is detachably connected to the gun body 02.

[0051] In this embodiment, the air inlet 11 is cylindrical.

[0052] In this embodiment, the air inlet 11 of the gun head 01 is inserted into the gun body 02. In other embodiments, the air inlet 11 of the gun head 01 may be fitted over the gun body 02.

[0053] See Figure 1 and Figure 4 In this embodiment, one of the gun heads 01 is a large-angle gun head 01, which includes:

[0054] The main body of the nozzle 01 includes a shell 1 with a gas passage. The gas passage includes an inlet 11 and an outlet 12. The outlet 12 is annular and has an outlet angle of 360°. The outlet 12 of the large-angle nozzle 01 has an outlet angle of 360°, thereby achieving maximum angular uniform heating of the heated object (usually a pipe).

[0055] In this embodiment, the large-angle gun head 01 includes a housing 1, the housing 1 includes a flat portion 13, the flat portion 13 smoothly transitions to the air inlet 11, the edge of the flat portion 13 includes two symmetrical straight surfaces 131 and an arc surface 132 in the shape of the number eight, and the two ends of the arc surface 132 smoothly transition to the two straight surfaces 131.

[0056] The outer shell 1 adopts this structure, which reduces the airflow difference on the flame outlet 2 compared to the inner and outer equal diameter circular ring structure, and makes the flame outlet 2 more uniform.

[0057] In other embodiments, the distribution and size of the flame outlets 21 can be designed to make the flame outlets 21 more uniform in the circumferential direction.

[0058] In this embodiment, the large-angle gun head 01 also includes a flame-emitting component 2, which is fixedly connected to the main body of the gun head 01. Multiple flame-emitting holes 21 are formed on the flame-emitting component 2. Before bending, the flame-emitting component 2 is a mesh plate. Compared to setting a nozzle, the mesh plate is easier to process, lower in cost, easier to clean, and less prone to clogging. The flame-emitting holes 21 are perpendicular to the flame-emitting component 2 (in the thickness direction) or inclined relative to the flame-emitting component 2.

[0059] In other embodiments, the firing element 2 may also be provided with multiple nozzles.

[0060] In this embodiment, the firing element 2 and the outer casing 1 are welded together. The outer casing 1 is formed by welding together two halves or more components.

[0061] In this embodiment, a connection structure for connecting with the gun body 02 is formed on the air inlet 11, and the connection structure includes an anti-detachment hole.

[0062] See Figure 2 and Figure 5 In this embodiment, one of the gun heads 01 is cylindrical, and the cylindrical gun head 01 fires in a straight line. The cylindrical gun head 01 has the same air inlet 11 as the large-angle gun head 01. The cylindrical gun head 01 does not have a firing element 2.

[0063] In other embodiments, the cylindrical gun head 01 with straight-line firing can be provided with a firing element 2, which has a mesh hole or a nozzle.

[0064] In other embodiments, the nozzle 01 with a straight firing direction can also have a variable diameter, with the cross-sectional dimension of its air outlet 12 being smaller than that of its air inlet 11.

[0065] See Figure 3 and Figure 6 In this embodiment, one of the gun heads 01 includes a cylindrical air inlet 11 and an air outlet 12, and the end face of the air outlet 12 is elliptical.

[0066] The nozzle 01 includes a cylindrical air inlet 11 and a tapered section. The tapered section gradually flattens along the gas flow direction, and the outlet end face of the tapered section is approximately elliptical, forming an outlet 12. The longer axis of the outlet 12 is larger than the diameter of the air inlet 11, while the narrower axis is smaller than the diameter of the air inlet 11. The approximately elliptical outlet 12 enables near-linear flameout, making it suitable for certain specific applications.

[0067] See Figure 7 In this embodiment, one of the gun heads 01 includes a cylindrical air inlet 11 and an arc-shaped air outlet 12, the angle of which is between 30° and 180°.

[0068] In this embodiment, the outer shell 1 also has side wings 14. The outer shell 1 comprises two half-shells, each half-shell having a side wing 14, and the two half-shells are welded together to form the outer shell 1. The side wings 14 can improve the structural strength of the outer shell 1, and also facilitate welding, ensuring a seal.

[0069] See Figure 8In this embodiment, from left to right, the cross-section of the air outlet 12 of the first gun head 01 includes four circular arcs and two line segments; the cross-section of the air outlet 12 of the second gun head 01 includes six line segments (with circular arc transitions between the line segments); the cross-section of the air outlet 12 of the third gun head 01 includes four line segments (with circular arc transitions between the line segments); the cross-section of the air outlet 12 of the fourth gun head 01 includes three line segments (with circular arc transitions between the line segments); the cross-section of the air outlet 12 of the fifth gun head 01 includes two line segments (with circular arc transitions between the line segments); and the cross-section of the air outlet 12 of the sixth gun head 01 includes one circular arc and two line segments. The outer shell 1 of the gun head 01 is symmetrical from left to right. The shape of the firing element 2 of these gun heads 01 is adapted to the shape of the air outlet 12. Figure 8 The exhaust angle of the six gun heads 01 is approximately 180°.

[0070] In this embodiment, Figure 9 The six gun heads 01 and Figure 8 The six gun heads 01 differ in that the position of the air outlet 12 relative to the air inlet 11 is adjusted, making the outer shell 1 of the gun head 01 asymmetrical. The shape of the firing element 2 of these gun heads 01 is adapted to the shape of the air outlet 12. The arc shape has one radius or multiple different radii.

[0071] In this embodiment, the manufacturer supplies various different gun heads 01, which users can select according to their actual needs. Figure 4 The large-angle nozzle 01 has the best heating effect on the pipe, but it cannot achieve radial separation. Figure 5 The nozzle 01 emits gas at a high speed and over a large area; Figure 6 The gun head 01 can shoot out a straight line of flame; Figure 7 The gun head 01 provides an arc-shaped flame. Figure 8 and Figure 9 The gun head 01 can provide flames of various shapes.

[0072] In this embodiment, Figure 2 and Figure 3 The air outlet angle of the air outlet 12 can be considered to be roughly the same.

[0073] The multi-angle flame-spraying device of this utility model embodiment has a large-angle nozzle 01, and the air outlet 12 of the large-angle nozzle 01 has an air outlet angle of 360°, which can simultaneously heat the entire circle of the heated pipe, improving the heating efficiency and quality; it also has multiple nozzles 01 with other flame-sparking angles, and the appropriate nozzle 01 can be selected according to the actual scenario requirements to meet more personalized needs.
