Detailed implementation manner

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Refer to Figures 1-6 , an online angle - adjustable soot blower, including a main soot blower pipe 8, a height - adjusting mechanism located on the upper side of the middle part of the main soot blower pipe 8, and an angle - adjusting mechanism located on the lower side of the tail end of the main soot blower pipe 8; the head end of the main soot blower pipe 8 extends into the furnace 1.

[0026] The height - adjusting mechanism includes a bracket 7 hinged to the upper side of the middle part of the main soot blower pipe 8. The bracket 7 is a hollow "door" - shaped structure, including a horizontal section and a vertical section. The middle of the horizontal section of the bracket 7 is rotatably connected with a driving gear 14 whose axis is along the vertical direction. On the left and right sides of the driving gear 14, connecting rods 15 are respectively arranged along the length direction of the horizontal section of the bracket 7, and the middle of the connecting rod 15 is connected to the bracket 7 through a bearing. The inner end of the connecting rod 15 is fixed with a driving gear a 161 meshing with the driving gear 14, the outer end of the connecting rod 15 is fixed with a driving gear b 162, and threaded rods 17 are respectively arranged along the length direction of the vertical sections on the left and right sides inside the bracket 7. The threaded rods 17 are connected to the inside of the bracket 7 through bearings, and a driven gear 13 meshing with the driving gear b162 is fixed on the threaded rod 17. The lower end of the threaded rod 17 is threadedly connected with a connecting main pipe 18, and the lower end of the connecting main pipe 18 contacts the ground.

[0027] Further, in order to facilitate the rotation of the driving gear 14, a handwheel 3 is fixed on the upper side of the driving gear 14, and a suspension bolt 2 is fixed on the handwheel 3.

[0028] The angle - adjusting mechanism includes an inner pipe 4 and an outer pipe 5. The upper end of the inner pipe 4 is hinged to the lower side of the tail end of the main soot blower pipe 8. The outer pipe 5 is sleeved on the outside of the lower end of the inner pipe 4. A limit chute 9 is arranged along the length direction of the inner wall of the outer pipe 5. On one side of the chute 9, a plurality of L - shaped fixed grooves 10 communicated with it are arranged at equal intervals. The end of the fixed groove 10 perpendicular to the chute 9 is communicated with the chute 9, and the end of the section of the fixed groove 10 parallel to the chute 9 extends downward. A limit block 12 matching the fixed groove 10 is arranged on the outside of the inner pipe 4. In order to make the limit block 12 move more conveniently, the cross - section of the limit block 12 is circular;

[0029] The bottom of the outer tube 5 is rotatably connected to an outer tube base 11, and the outer tube base 11 contacts the ground. A communication hole 6 is provided at the top of the inner tube 4, which can connect the air inside and outside the communication hole 6, enabling the inner tube 4 to smoothly expand and contract along the outer tube 5.

[0030] Working principle and usage process: The bracket 7 is used to suspend and fix the main soot blower, and the connecting main pipe 18 contacts the ground. When adjusting the height of the main soot blowing pipe 8, rotate the handwheel 3. The handwheel 3 drives the driving gear 14 to rotate, and the driving gear 14 drives the driving gear a 161 at the inner end of the two connecting rods 15 to rotate, thereby driving the two connecting rods 15 to rotate. The driving gear b 162 at the outer end of the two connecting rods 15 drives the driven gear 13 engaged therewith to rotate, thereby driving the threaded rod 17 to rotate. With the connecting main pipe 18 stationary, the threaded rod 17 spirally extends out of the connecting main pipe 18, causing the main soot blowing pipe 8 to move up and down;

[0031] When adjusting the angle of the main soot blowing pipe 8, lift the inner tube 4 to move the limiting block 12 on the outside of the inner tube 4 to the corner of the fixing groove 10, and then rotate the outer tube 5 to move the limiting block 12 on the outside of the inner tube 4 into the limiting sliding groove 9. Then, the inner tube 4 can be slid up and down. When the inner tube 4 slides to the required position, rotate the inner tube 4 in the reverse direction to make the limiting block 12 on the outside of the inner tube 4 enter the corresponding fixing groove 10. Release the inner tube 4, and the inner tube 4 drops due to gravity. The limiting block 12 then moves along the fixing groove 10 to its end, and the relative position of the inner tube 4 and the outer tube 5 is fixed. The bottom of the outer tube base 11 contacts the ground. When the inner tube 4 retracts into the outer tube 5, the tail end of the main soot blowing pipe 8 drops and the head end rises. When the inner tube 4 extends out of the outer tube 5, the tail end of the main soot blowing pipe 8 is raised and the head end drops.

[0032] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
