Description

Technical Field

[0001] This utility model relates to the field of combustion equipment technology, specifically a burner flame angle adjustment device. Background Technology

[0002] In industrial heating, welding and cutting, and boiler combustion, the burner, as the core energy output device, directly affects heating efficiency, work quality, and energy consumption through precise control of its flame angle. Currently available burner flame angle adjustment devices, limited by their structural design, struggle to meet the refined adjustment requirements under complex operating conditions.

[0003] A search revealed existing technology (application number: CN202323449323.2), which describes "a burner flame angle adjustment device and its box-type burner and burner." This utility model's burner flame angle adjustment device and its box-type burner and burner can adjust the gas flow direction in the case of a bent pipe, thereby making the flame angle after ignition spray out along the pipeline direction.

[0004] However, while existing burner flame angle adjustment devices and their box-type burners can adjust the gas flow direction in curved pipe conditions, thus ensuring the ignited flame is ejected along the pipe direction, they still have some shortcomings: traditional devices mostly use fixed brackets or single-axis hinge structures, resulting in a small flame angle adjustment range that cannot cover the multi-angle heating needs of large workpieces. The adjustment method relies on manual bolt tightening, leading to low angle adjustment accuracy, large repeatability errors, uneven temperature distribution in the heating zone, large temperature differences, and increased workpiece thermal deformation rate, especially in the precision casting field, resulting in a lower product qualification rate. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a burner flame angle adjustment device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a burner flame angle adjustment device, comprising: a main body assembly, disposed on the ground; an infusion assembly, disposed on the ground; a blowing assembly, disposed on the main body assembly; and a rotating assembly, disposed on the blowing assembly; wherein the rotating assembly comprises: a rotating ring, disposed on the blowing assembly, for driving the flame angle adjustment.

[0007] As a further description of the above technical solution:

[0008] The rotating assembly further includes: a support shell welded to the blower assembly; a base plate welded inside the support shell; a rotating shaft rotatably connected to the base plate; two sets of sliding plates threadedly connected to the rotating shaft; two sets of sliding rods, one end welded to one set of sliding plates and the other end slidably connected to the other set of sliding plates; a slider welded to the sliding rod; and a rotating rod rotatably connected at one end to the slider and at the other end to the rotating ring.

[0009] As a further description of the above technical solution:

[0010] The main components include: a housing, which is set on the ground; two sets of hinges, one end of which is welded to the housing; an opening and closing door, which is welded to the other end of the hinge; a locking assembly, which is set inside the housing; and a charging port, which is set inside the housing.

[0011] As a further description of the above technical solution:

[0012] The locking assembly includes: a base welded to the outer shell; two sets of locking pins slidably connected to the base; a spring, one end welded to the base and the other end welded to the locking pins; and a locking block welded to the door and slidably connected to the base.

[0013] As a further description of the above technical solution:

[0014] The infusion assembly includes: an oil tank, which is located on the ground; an infusion tube, one end of which is connected to the oil tank; and a pump, which is located at the other end of the infusion tube.

[0015] As a further description of the above technical solution:

[0017] As a further description of the above technical solution:

[0018] The rotating shaft is provided with a bidirectional thread for adjusting the angle of the flame ejection.

[0019] This utility model has the following beneficial effects:

[0020] The rotating component's shaft drives two sets of sliding plates to move in opposite directions via a bidirectional thread. This, combined with the transmission between the rotating rod and the rotating ring, expands the flame adjustment range compared to existing systems, covering the multi-angle heating needs of large workpieces. It offers high adjustment precision, low repeatability error, and improved accuracy compared to existing systems. This reduces temperature differences in the heating zone, lowers the workpiece's thermal deformation rate, and improves product qualification rates in the precision casting field.

The rotating component 4 includes: a rotating ring 48, which is set on the blower component 3 to drive the flame angle adjustment.

[0033] In this embodiment, the locking component and the rotating component constitute a burner flame angle adjustment device according to this application.

[0034] It should also be noted that in some embodiments, the burner flame angle adjustment device can be a flame angle adjustment device for industrial boilers, a flame angle adjustment device for welding and cutting, a flame angle adjustment device for metal forging, etc., wherein the flame angle adjustment device for industrial boilers can be, but is not limited to, a chain grate flame adjustment device, a circulating fluidized bed flame guide device, a waste heat boiler flame angle adjuster, etc. Figure 1 In this embodiment, the application scenario adapted to the burner flame angle adjustment device is an industrial boiler flame angle adjustment device. Of course, other types of burner flame angle adjustment devices can also adopt a similar structure for their application scenarios, which will not be elaborated on later.

[0035] Understandable, Figure 1This illustration only schematically shows some components of a burner flame angle adjustment device; the actual shape, size, position, and construction of these components are not subject to change. Figure 1 Due to limitations, a burner flame angle adjustment device may also include, compared to... Figure 1 More or fewer parts.

[0036] It should also be understood that the liquid pump 23 and the motor 31 were purchased from the market and are common knowledge in this field. They are only used and not modified, so the control method and circuit connection will not be described in detail.

[0037] In addition, in this embodiment, the rotating ring 48 of the rotating component 4 drives the end of the flame tube 34 to deflect and adjust the flame angle; the liquid delivery component 2 delivers fuel, the blowing component 3 provides combustion air, and the main component 1 provides installation support.

[0038] Specifically, the rotating assembly 4 also includes: a support shell 41, welded to the blower assembly 3; a base plate 42, welded inside the support shell 41; a rotating shaft 43, rotatably connected to the base plate 42; two sets of sliding plates 44, threadedly connected to the rotating shaft 43; two sets of sliding rods 45, one end welded to one set of sliding plates 44, and the other end slidably connected to the other set of sliding plates 44; a slider 46, welded to the sliding rod 45; and a rotating rod 47, one end rotatably connected to the slider 46, and the other end rotatably connected to the rotating ring 48.

[0039] In this embodiment, the rotation of the rotating shaft 43 causes the two sets of sliding plates 44 to move closer or further apart, and the rotating rod 47 is driven by the sliding rod 45 and the slider 46 to push and pull the rotating ring 48, thereby adjusting the angle of the rotating ring 48.

[0040] Specifically, the main component 1 includes: a housing 11, which is set on the ground; two sets of hinges 12, one end of which is welded to the housing 11; an opening and closing door 13, which is welded to the other end of the hinge 12; a locking component 14, which is set inside the housing 11; and a charging port 15, which is set inside the housing 11.

[0041] In this embodiment, the opening and closing door 13 rotates around the hinge 12 to realize the opening and closing of the outer shell 11, and the locking component 14 fixes the position of the opening and closing door 13; the charging port 15 supplies power to the device.

[0042] Specifically, the locking assembly 14 includes: a base 141, welded to the outer shell 11; two sets of locking pins 143, slidably connected to the base 141; a spring 142, one end of which is welded to the base 141 and the other end of which is welded to the locking pins 143; and a locking block 144, welded to the opening and closing door 13 and slidably connected to the base 141.

[0043] In this embodiment, when the door 13 is closed, the locking block 144 presses the locking pin 143 to compress the spring 142, and the locking pin 143 is engaged in the groove of the locking block 144 to achieve locking; pulling the locking pin 143 to compress the spring 142 can unlock the door.

[0044] Specifically, the infusion assembly 2 includes: an oil tank 21, which is installed on the ground; an infusion tube 22, one end of which is opened on the oil tank 21; and a pump 23, which is installed at the other end of the infusion tube 22.

[0045] With this setup, the liquid pump 23 operates to transport the fuel in the oil tank 21 to the blower 32 through the liquid delivery pipe 22, where it mixes with air and is then burned.

[0046] Specifically, the blowing assembly 3 includes: a motor 31, which is mounted on the main body assembly 1; a blower 32, which is mounted on the outer casing 11 and is fixedly connected to the liquid pump 23; a feed inlet 33, which is opened on the blower 32; and a flame pipe 34, one end of which is welded to the blower 32.

[0047] In this process, the motor 31 drives the blower 32 to operate and draw in air, which mixes with the fuel delivered by the liquid pump 23 inside the blower 32 and is then sprayed out from the flame pipe 34 and ignited to form a flame.

[0048] Specifically, the rotating shaft 43 is provided with a bidirectional thread for adjusting the angle of the flame ejection.

[0049] In this embodiment, rotating the shaft 43 in the forward direction brings the two sets of sliding plates 44 closer together, and the rotating rod 47 pushes the rotating ring 48 to deflect to one side; rotating in the reverse direction causes the rotating ring 48 to deflect to the other side, thus realizing bidirectional adjustment of the flame angle.

[0050] In actual use, the operator first opens the door 13, causing the locking pin 143 to slide, which in turn causes the spring 142 to contract and then extend. The charging port 15 is then connected to the power supply. The liquid pump 23 is turned on, causing the liquid inside the oil tank 21 to flow into the blower 32 through the infusion pipe 22. The motor 31 is turned on, causing the blower 32 to run. Combustible material is placed in the feed inlet 33. After ignition, the flame is ejected through the flame nozzle 34. If it is necessary to adjust the angle of the flame, the two-way thread on the rotating shaft 43 is used to rotate the rotating shaft 43, causing the two sets of sliding plates 44 to slide along the rotating shaft 43, which in turn causes the sliding rod 45 to slide, which in turn causes the slider 46 to slide, which in turn causes the rotating rod 47 to rotate. The rotation of the rotating rod 47 causes the rotating ring 48 to rotate, which in turn causes the flame nozzle 34 to rotate, thereby adjusting the angle of the flame.

[0051] The liquid pump 23 and the motor 31 are both electrically connected to the PLC controller, which is electrically connected to an external power supply. The PLC controller facilitates the power supply control of the electrical equipment, ensuring that the equipment can be powered on when needed, thus avoiding the situation where power cannot be supplied when power is required.

[0052] It should be noted that the controller can be a conventional known device that is controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific embodiments of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
