[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution for a novel boiler soot blower purge trajectory transformation device, including a boiler soot blower main body 1, a blowing pipe 3, and a blowing port 8. A blowing pipe 3 is provided on the boiler soot blower main body 1, and a blowing port 8 is provided on the blowing pipe 3. A connecting ring 5 is rotatably connected to the blowing pipe 3. Shading plates 7 are symmetrically installed on the connecting ring 5, and guide frames 9 are symmetrically installed on the connecting ring 5. Guide plates 15 are installed inside both guide frames 9. An arc-shaped groove adapted to the blowing pipe 3 is provided on the shading plate 7. When the shading plate 7 covers at the blowing port 8, it can prevent dust in the boiler from entering the blowing port 8.
[0021] As Figure 1 and Figure 2 shown, air outlet ports 10 are provided at the tops of both guide frames 9. The guide plates 15 are inclined and installed inside the guide frames 9. One end of the guide plate 15 is fixedly connected to the air outlet port 10. When the guide frame 9 is located at the blowing port 8, the inclined guide plate 15 inside can guide the air blown out from the blowing port 8 to blow the inner wall of one side of the boiler. One end of the boiler soot blower main body 1 is installed with a fixing plate 2. A through hole adapted to the blowing pipe 3 is provided on the fixing plate 2. An annular plate 4 is installed on the blowing pipe 3.
[0022] As Figure 3 shown, connecting rods 6 are symmetrically installed at one end of the connecting ring 5 away from the shading plate 7. Threaded sleeves 12 are provided at the ends of the two connecting rods 6 away from the connecting ring 5. Connecting cylinders 13 are threadedly connected to both threaded sleeves 12. Plug rods 14 are installed at one ends of the two connecting cylinders 13. Insertion holes 11 adapted to the plug rods 14 are annularly arranged on the annular plate 4. By rotating the two connecting cylinders 13, the connecting cylinders 13 move on the threaded sleeves 12, and the plug rods 14 are withdrawn from the insertion holes 11. The connecting ring 5 is rotated on the blowing pipe 3 to adjust the positions of the shading plate 7 and the guide frame 9, and then the connecting cylinders 13 are rotated in the reverse direction to insert the plug rods 14 into the insertion holes 11 to limit the position of the connecting ring 5.
[0023] The working principle of the present utility model is as follows: Rotate the two connecting cylinders 13. The connecting cylinders 13 move on the threaded sleeves 12, and the insertion rods 14 are withdrawn from the inside of the insertion holes 11. Rotate the connecting rod 6 to make the connecting ring 5 rotate on the blowing pipe 3, and rotate the guiding frame 9 to the blowing port 8. Then rotate the connecting cylinder 13 in the reverse direction to insert the insertion rod 14 into the insertion hole 11. The gas inside the blowing pipe 3 is discharged through the blowing port 8. When the guiding frame 9 is located at the blowing port 8, the inclined guiding plate 15 inside can guide the gas blown out from the blowing port 8 to blow the ash on one inner wall of the boiler. Then withdraw the insertion rod 14 from the inside of the insertion hole 11, rotate the connecting rod 6, and move the guiding frame 9 away from the blowing port 8. Neither the guiding frame 9 nor the shielding plate 7 is at the blowing port 8. The main body 1 of the boiler soot blower operates, and the blowing pipe 3 extends and rotates inside the boiler to perform the soot blowing work.
[0024] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, unless otherwise specifically stated and limited, are implemented according to the conventional means in this field.
