Description

Technical Field

[0001] The present application relates to the technical field of burners, and in particular to an adjustable burner. Background Art

[0002] A burner is a device that mixes fuel and air in a specific way and burns them to generate heat energy. Burners are usually used in industrial production, energy utilization, environmental protection and other fields.

[0003] In the related art, a burner includes a shell, on which a combustion tube and a plurality of air inlet tubes are disposed. The plurality of air inlet tubes are arranged along the circumference of the combustion tube, and the air inlet tubes are inclined toward the combustion tube.

[0004] Since the air inlet pipe is inclined toward the combustion tube, the flame range ejected from the combustion tube is fixed, resulting in that the flame of the burner cannot be adjusted according to different occasions, affecting the use of the burner and causing the burner to have low adaptability. Summary of the invention

[0005] In order to improve the problem that the range of the flame in the burner cannot be adjusted, the present application provides an adjustable burner.

[0006] The present application provides an adjustable burner, which adopts the following technical solution: An adjustable burner comprises a shell, a plurality of connecting pipes are arranged on the shell, a combustion pipe is arranged on the shell, an air intake pipe is arranged on the connecting pipe, a fastener is arranged on the shell, the fastener is used to fix the air intake pipe, and the opening of the air intake pipe is inclined to one side.

[0007] By adopting the above technical solution, the opening of the air intake pipe is tilted to one side, and the air intake pipe is fixed to the shell with fasteners. The staff can adjust the air intake pipe according to actual needs and adjust the tilt direction of the air intake pipe so that the range of the gas sprayed from the air intake pipe can be adjusted. The range of the ignition flame in the burner is the gas range, so that the range of the flame sprayed from the burner can be adjusted in a small range, so that the burner can adapt to different occasions and increase the adaptability of the burner.

[0008] Optionally, the shell is provided with a gas pipe for supplying gas to the air intake pipe, the gas pipe includes a first pipe, a second pipe and a third pipe, the second pipe is located between the first pipe and the third pipe, the first pipe is arranged on the connecting pipe, and the second pipe is inclined to one side.

[0009] By adopting the above technical solution, the opening direction of the first tube can be adjusted by tilting the second tube to one side. Since the first tube is arranged on the connecting tube and the air intake pipe is arranged on the connecting tube, when the staff rotates the gas supply pipe, the staff replaces the connecting tube so that the connecting tube can be installed on the gas supply pipe. At this time, the distance between the air intake pipe and the gas pipe can be changed, so that the air intake pipe can be adjusted over a wide range, and the range of gas ejected from the air intake pipe can be adjusted over a wide range, thereby further improving the adaptability of the burner.

[0010] Optionally, an outer shell is provided on the shell, a gear ring is rotatably connected to the outer shell, a mounting ring is provided on the air intake pipe, and the mounting ring and the gear ring are meshed with each other; when the gear ring rotates, the multiple air intake pipes all rotate synchronously.

[0011] By adopting the above technical solution, through the rotation of the gear ring, since the mounting ring and the gear ring can mesh, the gear ring drives the mounting ring to rotate, thereby allowing the air intake pipe to rotate. The staff only needs to rotate the gear ring to rotate multiple air intake pipes at one time, so that the staff does not need to rotate the air intake pipes one by one, reducing the staff's operating steps and allowing the staff to adjust the range of the burner flame more quickly.

[0012] Optionally, the fastener includes a limit strip, which is slidably arranged on the outer shell, and a plurality of limit grooves for inserting the limit strip are opened on the air intake pipe, and the limit grooves are distributed along the circumference of the air intake pipe; when the limit strip is inserted into the limit groove, the air intake pipe and the gear ring are fixed to each other.

[0013] By adopting the above technical solution, the staff slides the limit bar and inserts the limit bar into the limit groove to limit the intake pipe, so that the intake pipe and the gear ring can be fixed to each other, reducing the rotation of the connecting pipe on the intake pipe, so that the intake pipe can stably output gas and the burner can stably spray flames.

[0014] Optionally, the fastener further includes an elastic ring, the limiting strip is arranged on the elastic ring, and the outer shell is provided with a ring groove for the elastic ring to be inserted into; when the elastic ring is located in the ring groove, the limiting strip is inserted into the limiting groove.

[0015] By adopting the above technical solution, the staff installs the elastic ring in the ring groove so that the limit bar can be inserted into the limit groove. If the limit bar is not inserted into the limit groove, the elastic ring can partially protrude, so that the staff can clearly observe it, so that the staff can determine whether the intake pipe is fixed in place.

[0016] Optionally, a stop bar is slidably connected to the outer shell, and the stop bar is used to block the opening of the ring groove; when the elastic ring is located in the ring groove, the stop bar can block the ring groove.

[0017] By adopting the above technical solution, the ring groove is blocked by the stop strip, so that the elastic ring is not easily deformed, so that the elastic ring can be stably located in the ring groove, and the stop strip protects the elastic ring, so that the elastic ring can remain stable at a higher temperature.

[0018] Optionally, a rotating bar is rotatably connected to the outer shell, and a second rotating block is provided on the rotating bar. The rotating bar is located on the moving path of the elastic ring, and the second rotating block is located on the moving path of the stop bar; when the elastic ring is inserted into the ring groove, the second rotating block pushes the stop bar, and at this time the stop bar blocks the opening of the ring groove.

[0019] By adopting the above technical solution, the staff installs the elastic ring in the ring groove. Since the rotating bar is located on the moving path of the elastic ring, the rotating bar rotates, allowing the rotating bar to drive the second rotating block to move. In addition, the second rotating block is located on the moving path of the stop bar, so that the second rotating block can push the stop bar to move, allowing the stop bar to smoothly block the opening of the ring groove, thereby achieving the stable position of the stop bar in the ring groove, so that the staff does not need to manually move the stop bar, thereby reducing the staff's operating steps.

[0020] Optionally, a through hole is provided on the outer shell, an operating bolt for passing through the through hole is provided on the outer shell, a plurality of operating grooves are provided on the first tube, and the plurality of operating grooves are distributed along the circumference of the first tube; when the operating bolt is threadedly connected in the operating groove, the first tube is fixed on the connecting tube.

[0021] By adopting the above technical solution, multiple operating grooves are distributed along the length direction of the first pipe. When the operating bolts are threadedly connected to different operating grooves, the gas sprayed from the first pipe has different ranges, so that the first pipe and the connecting pipe can be fixed to each other, avoiding the shaking of the first pipe when spraying gas, thereby improving the stability of gas output.

[0022] Optionally, the operating bolt is provided with an elastic operating block, the operating block is provided with a dovetail block, and the stop strip is provided with a dovetail groove for inserting the dovetail block; when the limit strip is inserted into the limit groove, the dovetail block is inserted into the dovetail groove.

[0023] By adopting the above technical solution, when the limit strip is inserted into the limit groove, since the operating block is elastic, the staff can pull the operating block to insert the dovetail block into the dovetail groove, so that the stop strip and the limit strip can be fixed to each other, so that the stop strip can stably seal the annular groove, and the limit strip can be stably located in the limit groove.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. By tilting the opening of the air intake pipe to one side and fixing the air intake pipe to the shell with fasteners, the staff can adjust the air intake pipe according to actual needs and adjust the tilt direction of the air intake pipe so that the range of the gas sprayed from the air intake pipe can be adjusted. The range of the ignition flame in the burner is the gas range, so that the range of the flame sprayed from the burner can be adjusted in a small range, increasing the adaptability of the burner.

[0025] 2. The staff slides the limit bar and inserts it into the limit groove to limit the connecting pipe, so that the connecting pipe and the gear ring can be fixed to each other, reducing the rotation of the connecting pipe on the connecting pipe, so that the connecting pipe can stably output gas and the burner can stably spray flames.
