Technical Field

[0001] This utility model relates to the field of burner nozzle head structure optimization devices, and more specifically, to a device for burner head separation and tensioning. Background Technology

[0002] Existing rotary kiln burner nozzle heads are typically of a single, integral structure. A certain angle or swirl mechanism is incorporated at the front outlet to create a swirling flow of the primary air. Once installed and in use, this integral structure makes it difficult to perform individual maintenance and repairs on the nozzle head. However, the nozzle head is the most critical part of the burner, directly affecting burner efficiency and nitrogen oxide emissions. Located within the high-temperature system of the kiln, the internal structure is subjected to high temperatures, inevitably leading to problems such as deformation and gumming, thus requiring regular maintenance and repair. The integral structure undoubtedly increases the difficulty of maintenance, and an inadequate separation structure can also negatively impact burner performance. Summary of the Invention

[0021] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figure 1-3 As shown, the device for separating and tensioning the burner head in this utility model includes a pull rod 8, an outer sleeve 11, and a screw 13.

[0023] The tail of the pull rod 8 is connected to the screw 13. The outer sleeve 11 is fitted over the pull rod 8 and the screw 13. A first locking block 10 is provided on the pull rod 8, and a second locking block 15 is provided on the outer sleeve 11. One end of the first locking block 10 and the second locking block 15 is flat, and the other end is convex. The pull rod 8, the outer sleeve 11, and the screw 13 are located inside the nozzle head front pipe 1 and the burner rear pipe 3. The nozzle head front pipe 1 has a first locking groove that mates with the first locking block 10, and the burner rear pipe 3 has a second locking groove that mates with the second locking block 15. When the screw 13 rotates, it can drive the pull rod 8 and the outer sleeve to rotate, and the first locking block 10 and the second locking block 15 rotate accordingly, changing them to flat or convex surfaces, thus completing the unlocking or locking action with the external pipes.

[0024] Preferably, the outer sleeve 11 is provided with a strip groove, the pull rod 8 has a round hole in the corresponding strip groove position, and the elastic cylindrical pin 12 is provided in the strip groove and the round hole. The pull rod 8 drives the outer sleeve to rotate together through the elastic cylindrical pin 12.

[0025] Preferably, an adjusting nut 6 is fitted on the screw 13. Tightening the adjusting nut 6 causes the screw 13 to move forward or backward, which in turn causes the pull rod 8 to move forward or backward, thus separating or tensioning the pipe.

[0026] Preferably, a stop 14 is provided on the moving path of the adjusting nut 6, and the end of the screw 13 passes through the stop 14.

[0027] Preferably, the adjusting nut 6 is provided with a screw 5, which passes through the adjusting nut 6 and is fixed to the screw rod 13. When the screw 5 is in the tightened state, the adjusting nut 6 cannot be rotated.

[0028] Preferably, a lever handle 7 is provided at the tail of the screw 13. By rotating the lever handle 7, the screw 13 is rotated, and the screw 13 drives the pull rod 8 to rotate together. The elastic cylindrical pin 12 on the pull rod 8 drives the outer sleeve rod to rotate together.

[0029] Preferably, the bottom of the pull rod 8 and the outer sleeve 11 is provided with a support block 9.

[0030] Preferably, a washer 4 is fitted on the screw 13.

[0031] Preferably, the nozzle head front pipe 1 and the burner rear pipe 3 are sealed together by graphite packing 2.

[0032] The method of using this utility model is as follows:

[0033] Nozzle head separation: such as Figure 1As shown, after the burner is installed, the convex surface of the first locking block 10 on the pull rod 8 is tightly fitted with the first locking groove of the nozzle head front pipe 1; the convex surface of the second locking block 15 on the outer sleeve 11 is tightly fitted with the second locking groove of the burner rear pipe 3. At this time, the nozzle head front pipe 1 and the burner rear pipe are tensioned, and the two pipes are sealed with graphite packing 2. During the head separation operation, loosen the screw 5 on the adjusting nut 6, turn the adjusting nut 6 to move it backward until it is tight with the stop block 14, continue to tighten the adjusting nut 6, so that the screw 13 moves forward, driving the pull rod 8 forward, and the locking block 10 on the pull rod 8 pushes the nozzle head front pipe 1 forward, at which point the pipes are separated. Rotate the lever handle 7 so that the first locking block 10 and the second locking block 15 face upward (as shown). Figure 2 As shown in the figure, at this point, the front pipe 1 of the nozzle head can be pulled out to completely separate it from the burner.

[0034] Nozzle head tension: such as Figure 2 As shown, rotate lever handle 7 so that the flat surfaces of the first locking block 10 and the second locking block 15 face upwards, install the nozzle head front pipe 1, and then rotate lever handle 7 so that the convex surfaces of the first locking block 10 and the second locking block 15 face upwards. Loosen screw 5 on adjusting nut 6, and turn adjusting nut 6 to move it forward until it is flush with washer 4. Continue to tighten adjusting nut 6, causing screw 13 to move backwards, which in turn moves pull rod 8 backwards. The first locking block 10 on pull rod 8 pulls the nozzle head front pipe 1 backwards, at which point the pipe is tensioned. Finally, tighten adjusting nut 6.
