Description

Technical Field

[0001] This application relates to the technical field of burners, and in particular to a burner head. Background Technology

[0002] A burner is a device that mixes air and fuel in a certain proportion and ignites them to ensure stable combustion, thereby converting the fuel into heat and light energy. It is widely used in boilers, smelting furnaces, gas stoves and other applications.

[0003] In related technologies, the burner includes a shell and a sleeve. The sleeve is fixedly connected to the shell. The shell is provided with a fuel pipe for conveying fuel. The sleeve is provided with a plug groove for inserting the fuel pipe. The end face of the fuel pipe away from the shell is provided with a discharge port. A mixing area is formed between the discharge port and the sleeve.

[0004] Because the fuel output direction is consistent with the axis of the bushing, the fuel does not have much time to mix with the air after entering the mixing zone, and it will be output from the bushing outlet. The low degree of mixing between fuel and air leads to some fuel being wasted due to incomplete combustion, which increases the energy consumption cost of the burner. Utility Model Content

[0005] In order to improve the mixing degree of fuel and air, this application provides a burner head.

[0006] The burner head provided in this application adopts the following technical solution: A burner head includes a housing and a sleeve. The sleeve is fixedly connected to the housing. The housing has a fuel pipe for conveying fuel inside. The sleeve has a insertion groove for inserting the fuel pipe. A mixing area is formed between the outer surface of the fuel pipe and the sleeve. The fuel pipe has multiple through holes, through which fuel can flow to the mixing area.

[0007] By adopting the above technical solution, multiple through holes are opened on the fuel pipe, allowing the fuel in the fuel pipe to flow to the mixing area through multiple through holes. The fuel can enter the mixing area from multiple directions, allowing the air and fuel to be mixed more fully, reducing the waste of fuel due to incomplete combustion, thereby improving the fuel utilization rate and reducing the energy consumption cost of the burner.

[0008] Optionally, the plurality of through holes are distributed along the circumferential outer surface of the fuel pipe, and the fuel in the fuel pipe can be radially output through the through holes.

[0009] By adopting the above technical solution, multiple through holes are distributed along the circumferential outer surface of the fuel pipe, allowing the fuel in the fuel pipe to be radially output into the fuel channel through the through holes. Compared with output from the discharge port in the same direction as the fuel output, the through holes on the circumferential outer surface of the fuel pipe can reduce the fuel flow speed and enhance the rotation angle of the airflow, allowing the fuel to mix with the air for more time in the mixing zone, thereby improving the degree of mixing between the fuel and the air.

[0010] Optionally, the fuel pipe includes a feed pipe and a connector pipe, the connector sleeve is disposed on the feed pipe, the connector pipe has a placement groove for inserting the feed pipe, and a plurality of through holes are formed on the circumferential outer surface of the connector pipe.

[0011] By adopting the above technical solution, the connector sleeve is installed on the feed pipe, allowing the connector sleeve to be removed from the feed pipe. This enables the replacement of different types of connector sleeves to suit different application scenarios. Operators can replace the new connector sleeve independently, reducing the replacement cost of the entire burner equipment and thus extending the service life of the equipment.

[0012] Optionally, the placement groove has a locking block on its wall, and the conveying pipe has a fixing groove for the locking block to be inserted and slid. The fixing groove extends along the length of the conveying pipe, and the wall of the fixing groove has a locking slot for the locking block to be inserted. Multiple locking slots are provided. When the locking block is inserted into different locking slots, the connector pipe is fixed at different lengths of the conveying pipe.

[0013] By adopting the above technical solution, the operator inserts the slot on the connector pipe into the fixed slot, then slides it to the appropriate position of the slot opening, and then rotates the connector pipe to insert the card into the slot, so as to fix the connector pipe and the conveying pipe. The operator can adjust the range of the mixing area, so that the burner can be adapted to different equipment, and it is convenient for the operator to adjust the position of the connector pipe on the conveying pipe.

[0014] Optionally, a guide slope is provided on the wall of the card slot. The distance from the guide slope to the card slot axis gradually decreases along the direction in which the card block is inserted into the card slot. The guide slope is used to guide the card block to be inserted into the card slot.

[0015] By adopting the above technical solution, the distance from the guide slope to the card slot axis gradually decreases along the direction of the card block insertion into the card slot, so that the card block can be inserted into the card slot more smoothly along the direction of the guide slope, so that the workers can fix the connector pipe to the conveying pipe.

[0016] Optionally, the wall of the fixing groove is provided with multiple spring blocks, and the multiple spring blocks are all located on the moving path of the locking block; when the locking block abuts against the spring block, the locking block aligns with the corresponding locking groove.

[0017] By adopting the above technical solution, when the card block abuts against different spring blocks, the card block can be aligned with different card slots. The operator can sense the alignment of the card block and the card slot through the resistance of the spring block, which makes it easier for the operator to align the card block with the card slot, reducing the time required for the operator to align the position, and providing convenience for the operator to fix the connector pipe to the conveying pipe.

[0018] Optionally, a limiting rod is slidably connected to the card block, a limiting hole is provided on the connector tube for the limiting rod to be inserted and slid, and a groove is provided on the bottom wall of the card slot; when the limiting rod is inserted into the groove, the card block is fixed in the card slot.

[0019] By adopting the above technical solution, after the card block is inserted into the card slot, the worker inserts the limiting rod into the groove to further strengthen the fixation between the card block and the card slot, reduce the possibility of the card block coming out of the card slot, and thus make the fixation between the connector pipe and the conveying pipe more reliable.

[0020] Optionally, the sleeve is provided with a conveying ramp, and the distance from the conveying ramp to the outer shell axis gradually increases along the direction of the sleeve closer to the outer shell. The conveying ramp is used to guide air.

[0021] By adopting the above technical solution, the distance from the conveying inclined surface to the outer shell axis gradually increases along the direction of the sleeve closer to the outer shell. Air can be guided along the inclined direction of the conveying inclined surface, which is conducive to the full mixing of air and fuel and the cyclic combustion of air and fuel.

[0022] In summary, this application includes at least one of the following beneficial technical effects: By having multiple through holes on the fuel pipe, the fuel can flow through multiple holes to the mixing area. The fuel can enter the mixing area from multiple directions, allowing the air and fuel to mix more thoroughly. This reduces fuel waste due to incomplete combustion, thereby improving fuel utilization and reducing the energy consumption cost of the burner.

[0023] By distributing multiple through holes along the circumferential outer surface of the fuel pipe, the fuel inside the fuel pipe can be radially output into the fuel channel through the through holes. Compared with output from the discharge port in the same direction as the fuel output, the through holes on the circumferential outer surface of the fuel pipe can reduce the fuel flow speed and enhance the rotation angle of the airflow, so that the fuel can have more time to mix with the air in the mixing zone, thereby improving the degree of mixing between fuel and air.

Detailed Implementation

[0026] The following is in conjunction with the appendix Figure 1 - The figure provides a further detailed description of this application.

[0027] This embodiment discloses a burner head. (Refer to...) Figure 1 and Figure 2 A burner head includes a housing 1 and a sleeve 2, with the sleeve 2 fixedly connected to the outer surface of the housing 1. Multiple fuel pipes 3 are fixedly connected to the inner surface of the housing 1, and the fuel pipes 3 are used to transport fuel. Multiple slots 21 for inserting the fuel pipes 3 are formed on the inner surface of the sleeve 2. A mixing area 22 is formed between the outer surface of the fuel pipe 3 and the sleeve 2 through the insertion of the fuel pipe 3 into the slots 21.

[0028] Reference Figure 2 The fuel pipe 3 includes a feed pipe 31 and a connector pipe 32. The connector pipe 32 has a placement groove 321 for the feed pipe 31 to be inserted and slid. The feed pipe 31 is fixedly connected to the outer casing 1 and is used to connect to the fuel device to realize the delivery of fuel.

[0029] Reference Figure 3 Multiple through holes 322 are provided on the outer surface of the connector pipe 32. All through holes 322 are connected to the mixing area 22. The multiple through holes 322 are arranged in an array along the circumferential outer surface of the connector pipe 32. The fuel in the fuel pipe 3 can be output radially through the through holes 322.

[0030] Reference Figure 2 and Figure 3On both sides of the placement groove 321, locking blocks 323 are fixedly connected to the groove walls. On both sides of the conveying pipe 31, a fixing groove 311 is formed on the outer surface for the locking blocks 323 to be inserted and slid. The fixing groove 311 extends along the length of the conveying pipe 31 and penetrates the end face of the conveying pipe 31 away from the outer shell 1. Multiple locking slots 312 are formed on the groove walls of the fixing groove 311 for the locking blocks 323 to be inserted. These multiple locking slots 312 are arranged in an array along the length of the fixing groove 311. When the locking blocks 323 are inserted into different locking slots 312, the connector pipe 32 is fixed at different lengths of the conveying pipe 31 to achieve variations in the range of the mixing area 22.

[0031] Reference Figure 3 Guide slopes 313 are provided on both opposite sides of the slot wall of the slot 312. The distance from the guide slope 313 to the axis of the slot 312 gradually decreases along the direction in which the block 323 is inserted into the slot 312. The block 323 can be inserted into the slot 312 more smoothly along the inclined direction of the guide slope 313, so that the operator can rotate the block 323 into the slot 312 in the appropriate position.

[0032] Reference Figure 3 and Figure 4 Multiple spring blocks 314 are fixedly connected to the wall of the fixed groove 311 near the axis of the conveying pipe 31. The multiple spring blocks 314 are arranged in an array along the length of the conveying pipe 31, and all of the multiple spring blocks 314 are located on the moving path of the locking block 323. When the locking block 323 abuts against the spring block 314, the locking block 323 is aligned with the adjacent locking slot 312. The operator confirms the alignment of the locking block 323 with the locking slot 312 by feeling the resistance of the spring block 314, which makes it easier for the operator to insert the locking block 323 into the locking slot 312.

[0033] Reference Figure 3 A through hole 324 is formed on the surface of the locking block 323 near the feed pipe 31, extending through to the outer surface of the connector pipe 32. A limiting rod 325 is slidably connected inside the through hole 324, extending out of the through hole 324. A groove 315 is formed on the groove wall of the locking groove 312 near the axis of the feed pipe 31, for inserting the limiting rod 325. A fixing block 326 is slidably connected on the outer surface of the connector pipe 32, and a limiting groove 327 is formed on the limiting rod 325 for inserting the fixing block 326. When the locking block 323 is inserted into the locking groove 312, the limiting rod 325 is aligned with the groove 315. The operator inserts the limiting rod 325 into the groove 315 and then inserts the fixing block 326 into the limiting groove 327, thus fixing the locking block 323 in the locking groove 312.

[0034] Reference Figure 2The sleeve 2 has a conveying ramp 23 on the surface of the slot 21. The distance from the conveying ramp 23 to the axis of the outer shell 1 gradually increases along the direction of the sleeve 2 towards the outer shell 1. The air can be better guided through the inclined direction of the conveying ramp 23, which is conducive to the mixing of air and fuel.

[0035] The implementation principle of the burner head of the present application embodiment is as follows: When the operator inserts the locking blocks 323 on opposite sides of the inner surface of the connector tube 32 into the corresponding fixing grooves 311, and then moves them to a suitable position and abuts against the spring block 314, the locking blocks 323 and the locking grooves 312 are aligned. The operator rotates the connector tube 32 to insert the locking blocks 323 into the locking grooves 312, and then inserts the limiting rod 325 into the groove and the fixing block 326 into the limiting groove 327, so as to fix the connector tube 32 and the conveying tube 31 to each other.
