Description

Technical Field

[0001] This application relates to the technical field of burners, and in particular to a multi-flame nozzle device. Background Technology

[0002] In welding operations, to improve welding quality, it is often necessary to perform preheating treatment before welding and postheating treatment after welding. Currently, preheating and postheating are usually accomplished using gas-fired heating torches, which use gas as fuel to spray flames from the torch to heat the workpiece according to certain process conditions.

[0003] In related technologies, heating guns are usually equipped with a single nozzle, which means that the heating gun can only heat a single point when performing preheating treatment before welding and postheating treatment after welding, resulting in low heating efficiency and room for improvement. Summary of the Invention

[0004] To improve the heating efficiency of the equipment, this application provides a multi-flame nozzle device.

[0005] This application provides a multi-flame nozzle device, which adopts the following technical solution:

[0006] A multi-flame nozzle device includes a main gas pipe and nozzles, and also includes a dispersion pipe. The dispersion pipe is connected to the main gas pipe and is detachably fixed to the main gas pipe. There are multiple nozzles, which are detachably fixed to the dispersion pipe. The multiple nozzles and the main gas pipe are respectively located on both sides of the dispersion pipe, and the multiple nozzles are spaced apart along the axial direction of the dispersion pipe.

[0007] By adopting the above technical solution, multiple nozzles can simultaneously spray flames to heat multiple points during use, thereby improving the efficiency of heating and baking.

[0008] Optionally, the number of nozzles is three, and the dispersion tube includes:

[0009] The four-way pipe has a first end, a second end, a third end and a fourth end, the first end, the second end, the third end and the fourth end are arranged in sequence around the intersection of the four-way pipe, the first end is connected to the main air pipe, and a nozzle is connected to the third end;

[0010] Two sleeves are provided, each sleeve being connected to the second end and the fourth end respectively; and

[0011] The tubes are inserted one-to-one into the sleeves, and the tubes are slidably connected to the sleeves along the axial direction. The other two nozzles are respectively connected to the ends of the two tubes facing away from the sleeves, and the tubes are sealed to the sleeves.

[0012] The multi-flame nozzle device also includes a drive structure that causes the through-tube to slide relative to the sleeve.

[0013] By adopting the above technical solution, the driving structure drives the pipe to slide relative to the sleeve along the axial direction, thereby realizing the adjustable spacing between adjacent nozzles.

[0014] Optionally, the driving structure includes:

[0015] A stud, fixed to the outside of the sleeve and parallel to the sleeve; and

[0016] A drive sleeve is fitted onto the stud and threadedly connected to the stud, and the through tube slides synchronously along the axial direction with the drive sleeve.

[0017] By adopting the above technical solution, rotating the drive sleeve and driving the through-tube to slide relative to the sleeve along the axial direction through the threaded connection between the drive sleeve and the stud, the spacing between adjacent nozzles can be adjusted.

[0018] Optionally, the tube is provided with two clamping rods, which are clamped on the drive sleeve. The outer wall of the drive sleeve is provided with a drive ring groove, and both clamping rods are inserted into the drive ring groove. The drive sleeve is rotatably connected to the two clamping rods in the circumferential direction.

[0019] By adopting the above technical solution, when the drive sleeve is rotated, the tube slides axially along the drive sleeve, thereby realizing the adjustable spacing between adjacent nozzles.

[0020] Optionally, the drive structure further includes a support plate, which is sleeved on the through tube and slidably connected to the through tube, and the support plate is fixedly connected to the stud.

[0021] By adopting the above technical solution, the support plate provides support for the stud, making the stud less prone to deformation or shaking, thus improving the stability of the stud during use.

[0022] Optionally, it also includes a synchronization structure that drives the gas in the dispersion tube to simultaneously enter multiple of the nozzles.

[0023] By adopting the above technical solution, the gas in the dispersion tube enters the nozzle simultaneously, ensuring the consistency of ignition of multiple nozzles.

[0024] Optionally, the synchronization structure includes:

[0025] Two sealing arc plates are provided, which are inserted through both ends of the dispersion tube. The sealing arc plates are slidably connected to the dispersion tube along the axial direction. The sealing arc plates are stationary relative to the dispersion tube in the circumferential direction. The two sealing arc plates abut against each other in the middle of the dispersion tube. The sealing arc plates are provided with a connecting hole corresponding to the nozzle.

[0026] A baffle plate, fixed to the end of the sealing arc plate away from the main air pipe, the baffle plate passing through the dispersion pipe and being sealed to the dispersion pipe; and

[0027] Two elastic elements are provided at both ends of the dispersion tube, and the two elastic elements cause the two sealing arc plates to tend to keep abutting against each other.

[0028] When the pressure inside the dispersion tube reaches a set value, the gas drives the two baffles and the two sealing arc plates to move away from each other, so that the connecting hole connects with the corresponding nozzle.

[0029] By adopting the above technical solution, when the pressure inside the dispersion tube reaches the set value, the gas drives the two baffles and two sealing arc plates to move away from each other, so that the connecting hole connects with the corresponding nozzle, allowing the gas in the dispersion tube to enter the nozzle simultaneously, ensuring the consistency of ignition of multiple nozzles. At the same time, the gas is pressurized before entering the nozzle, improving the flame jetting capability.

[0030] Optionally, the synchronization structure further includes a guide post, which is disposed on the side of the partition away from the sealing arc plate, and the guide post passes through the sealing plate at the end of the dispersion tube and is slidably connected to the sealing plate along the axial direction.

[0031] By adopting the above technical solution, the sealing arc plate slides only axially in the dispersion tube, and does not rotate circumferentially in the dispersion tube.

[0032] Optionally, the synchronization structure further includes:

[0033] Two adjusting plates are respectively located at both ends of the dispersing tube, and the adjusting plates are positioned between the elastic element and the sealing plate; and

[0034] An adjusting member is inserted through the sealing plate and threadedly connected to the sealing plate. The adjusting member is stationary relative to the adjusting plate in the axial direction and rotatably connected to the adjusting plate in the circumferential direction.

[0035] By adopting the above technical solution, the rotation adjustment component can adjust the compression of the elastic component through the threaded connection between the adjustment component and the sealing plate, so as to facilitate the adjustment of the pressure setting value. That is, when the pressure in the dispersion tube reaches the setting value, the synchronization structure enables the nozzle to connect with the dispersion tube.

[0036] Optionally, multiple nozzles are hinged to the dispersion tube.

[0037] By adopting the above technical solution, the angle of the nozzle can be adjusted according to the usage environment.

[0038] In summary, this application includes at least one of the following beneficial technical effects:

[0039] 1. During use, multiple nozzles can simultaneously spray flames to heat multiple points, improving the efficiency of heating and baking;

[0040] 2. When the pressure inside the dispersion tube reaches the set value, the gas drives the two baffles and the two sealing arc plates to move away from each other, so that the connecting hole connects with the corresponding nozzle, allowing the gas in the dispersion tube to enter the nozzle simultaneously, ensuring the consistency of ignition of multiple nozzles; at the same time, the gas is pressurized before entering the nozzle, improving the flame jetting capability.

[0051] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0052] This application discloses a multi-flame nozzle device.

[0053] Example 1

[0054] Reference Figure 1 and Figure 2 The multi-flame nozzle device includes a main gas pipe 10, a nozzle 20, and a dispersion pipe 30.

[0055] The dispersion tube 30 includes a four-way tube 31 and sleeves 32. Specifically, the four-way tube 31 has a first end 311, a second end 312, a third end 313, and a fourth end 314, which are sequentially arranged around the intersection of the four-way tube 31. The first end 311 is threadedly connected to the main air tube 10. There are two sleeves 32, which are threadedly connected to the second end 312 and the fourth end 314, respectively.

[0056] There are three nozzles 20. One nozzle 20 is threaded to the fourth end 314, and the other two nozzles 20 are threaded to the ends of the two sleeves 32 away from the four-way pipe 31 via 90° elbows. The three nozzles 20 are parallel to each other and are set away from the main air pipe 10.

[0057] The nozzle 20 has a cavity 22, inside which a baffle 21 is fixed. The baffle 21 divides the cavity 22 into a combustion chamber and a flame ejection chamber. The combustion chamber is located on the side closer to the main gas pipe 10, and the flame ejection chamber is located on the side farther from the main gas pipe 10. A gas inlet 23 is located at the bottom of the inner cavity of the nozzle 20, communicating with the dispersion pipe 30 and the combustion chamber to allow gas to enter the combustion chamber. Multiple air inlets 24 are provided on the side wall of the nozzle 20, communicating with each other to provide oxygen for the combustion of gas within the combustion chamber. A flame channel 211 is provided on the baffle 21, allowing the gas burning in the combustion chamber to be ejected through the flame channel 211. A through hole 212 is also provided on the baffle 21, which can both supplement oxygen to the combustion chamber and serve as a flame ejection channel.

[0058] The implementation principle of Example 1 is as follows: when in use, the three nozzles 20 can spray flames simultaneously to heat multiple points, which improves the efficiency of heating and baking.

[0059] Example 2

[0060] Reference Figure 3 and Figure 4 The difference between this embodiment and Embodiment 1 is that the multi-flame nozzle device further includes a hinge structure 60, through which the nozzle 20 is hinged to the dispersion tube 30. Specifically, the hinge structure 60 includes a hinge ball 61, a connector 63, and a threaded joint 62. The nozzle 20 has an air inlet pipe 25, and the hinge ball 61 is fixed to the end of the air inlet pipe 25. The hinge ball 61 has an air inlet channel 611 communicating with the air inlet pipe 25. The connector 63 has a hemispherical groove 631, which allows the hinge ball 61 to be partially embedded and is adapted to fit the hinge ball 61. The threaded joint 62 is sleeved on the air inlet pipe 25. The threaded joint 62 has a spherical surface 621 on the side facing the hinge ball 61. The threaded joint 62 is threadedly connected to the connecting sleeve to connect the hinge ball 61 to the connector 63. The connector 63 can be connected to the fourth end 314 and the sleeve 32 to hinge the three nozzles 20 to the dispersion tube 30.

[0061] The implementation principle of Example 2 is as follows: the nozzle 20 is hinged to the dispersion tube 30 through the hinge structure 60, so that the angle of the nozzle 20 can be adjusted as needed when the equipment is in use, thus expanding the applicability of the equipment.

[0062] Example 3

[0063] Reference Figure 5 and Figure 6The difference between this embodiment and Embodiment 1 is that the dispersion tube 30 includes a four-way tube 31, a sleeve 32, and a through tube 33. Specifically, the four-way tube 31 has a first end 311, a second end 312, a third end 313, and a fourth end 314, which are sequentially arranged around the intersection of the four-way tube 31. The first end 311 is threadedly connected to the main air pipe 10. There are two sleeves 32, which are threadedly connected to the second end 312 and the fourth end 314, respectively. There are also two through tubes 33, which are inserted one-to-one into the sleeves 32. The outer diameter of the through tube 33 is equal to the inner diameter of the sleeve 32. The through tube 33 is slidably connected to the sleeve 32 along the axial direction. The end of the through tube 33 extending out of the sleeve 32 is threadedly connected to the nozzle 20 through a 90° bend. A sealing ring is fitted onto the end of the tube 33 that is inserted into the sleeve 32, and the sealing ring seals the gap between the sleeve 32 and the tube 33.

[0064] The difference between this embodiment and Embodiment 1 is that the multi-flame nozzle device further includes a drive structure 40, which is used to drive the through-tube 33 to slide relative to the sleeve 32. Specifically, the drive structure 40 includes a stud 41 and a drive sleeve 42. A base plate 321 is fixed on the outer wall of the sleeve 32, and one end of the stud 41 is fixed to the base plate 321. The axis of the stud 41 is parallel to the axis of the sleeve 32. A support plate 43 is sleeved on the through-tube 33, and the through-tube 33 is slidably connected to the support plate 43 along the axial direction. The support plate 43 is fixedly connected to the other end of the stud 41 to prevent the stud 41 from shaking or deforming. The drive sleeve 42 is sleeved on the stud 41 and is threadedly connected to the stud 41.

[0065] When the drive sleeve 42 is rotated, the through tube 33 slides axially with the drive sleeve 42. Specifically, a drive ring groove 421 is provided on the outer side wall of the drive sleeve 42, and two clamping rods 331 are fixed on the outer side wall of the through tube 33. The two clamping rods 331 are clamped on the drive sleeve 42 and inserted into the drive ring groove 421. The drive sleeve 42 is rotatably connected to the two clamping rods 331 in the circumferential direction.

[0066] The implementation principle of Example 3 is as follows: the distance between adjacent nozzles 20 can be adjusted by driving the through pipe 33 to slide relative to the sleeve 32 through the drive structure 40, so as to heat and bake the workpiece with flames of different sizes.

[0067] Example 4

[0068] The difference from Example 1 is that, referring to Figure 7 and Figure 8The dispersion tube 30 is a straight tube, and its middle part is threaded to the main air pipe 10. The dispersion tube 30 and the main air pipe 10 are perpendicular to each other. The axis of the main air pipe 10 bisects the dispersion tube 30. Multiple nozzles 20 are connected to the dispersion tube 30 through joints. The multiple nozzles 20 are evenly distributed along the axial direction of the dispersion tube 30. The connection points of the multiple nozzles 20 and the dispersion tube 30 are all located between the two ends of the dispersion tube 30.

[0069] The difference from Example 1 is that, referring to Figure 8 and Figure 9 The multi-flame nozzle device also includes a synchronization structure 50, which is used to drive the gas in the dispersion tube 30 into multiple nozzles 20 simultaneously. Specifically, the synchronization structure 50 includes a sealing arc plate 51, a partition plate 52, and an elastic element 53. The sealing arc plate 51 is arranged in an arc shape, with the included angle of the sealing arc plate 51 being less than 90°. There are two sealing arc plates 51, which are respectively inserted at both ends of the dispersion tube 30 and abut against each other at the middle of the dispersion tube 30. The sealing arc plates 51 can slide axially in the dispersion tube 30. The sealing arc plate 51 is used to seal the connection between the nozzle 20 and the dispersion tube 30, and the sealing arc plate 51 has a connecting hole 511 corresponding to the nozzle 20. The baffle 52 is fixed to the end of the sealing arc plate 51 away from the main air pipe 10. The baffle 52 passes through the dispersion pipe 30 and is sealed to the dispersion pipe 30. The baffle 52 can slide axially in the dispersion pipe 30. The elastic element 53 is a compression spring. Two elastic elements 53 are respectively provided in the dispersion pipe 30 and located at both ends of the dispersion pipe 30. The elastic elements 53 are located between the sealing plate 34 and the baffle 52 of the dispersion pipe 30. The two elastic elements 53 make the two sealing arc plates 51 tend to keep abutting against each other.

[0070] Initially, the two sealing arc plates 51 remain in contact with each other under the action of the two elastic elements 53. As the gas continuously enters the dispersion tube 30 through the main gas pipe 10, the pressure in the dispersion tube 30 continuously increases. When the pressure in the dispersion tube 30 reaches the set value, the gas drives the two baffles 52 and the two sealing arc plates 51 to slide away from each other in the dispersion tube 30, so that the connecting hole 511 is connected to the corresponding nozzle 20. This allows the gas in the dispersion tube 30 to enter multiple nozzles 20 at the same time, ensuring the consistency of the ignition of multiple nozzles 20.

[0071] To ensure that the sealing arc plate 51 slides only axially within the dispersion tube 30 and does not rotate circumferentially relative to the dispersion tube 30, the synchronization structure 50 also includes a guide post 54. The guide post 54 is fixed to the side of the partition plate 52 facing away from the sealing arc plate 51. The guide post 54 passes through the sealing plate 34 of the dispersion tube 30 and is slidably connected to the sealing plate 34. The guide post 54 can be a non-cylindrical shape, such as a square prism or a triangular prism. The guide post 54 can also be a cylinder. When the guide post 54 is a cylinder, it is eccentrically positioned relative to the dispersion tube 30.

[0072] To allow for adjustment of the pressure setpoint, the synchronization structure 50 also includes an adjusting plate 55 and an adjusting member 56. There are two adjusting plates 55, each located within the dispersion tube 30. The adjusting plates 55 are positioned between the elastic member 53 and the sealing plate 34 of the dispersion tube 30, maintaining contact with the elastic member 53. The adjusting member 56 is a screw, passing through and threadedly connected to the sealing plate 34 of the dispersion tube 30. The adjusting member 56 passes through and is rotatably connected to the adjusting plate 55. Two retaining rings are provided on both sides of the adjusting plate 55, clamping the adjusting member 56. These two retaining rings clamp both sides of the adjusting plate 55, allowing the adjusting plate 55 to slide axially relative to the sealing plate 34 when the adjusting member 56 is rotated.

[0073] The implementation principle of Example 4 is as follows: Initially, the two sealing arc plates 51 are kept in contact with each other under the action of the two elastic elements 53. As the gas continuously enters the dispersion pipe 30 through the main gas pipe 10, the pressure in the dispersion pipe 30 continuously increases. When the pressure in the dispersion pipe 30 reaches the set value, the gas drives the two baffles 52 and the two sealing arc plates 51 to slide away from each other in the dispersion pipe 30, so that the connecting hole 511 is connected to the corresponding nozzle 20, thereby allowing the gas in the dispersion pipe 30 to enter multiple nozzles 20 at the same time, ensuring the consistency of the ignition of multiple nozzles 20.

[0074] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
