Description

[0037] Working principle: During use, when it is necessary to perform soot blowing operation on the interior of the industrial equipment 1, the motor 503 is started, and the rotation of the motor 503 drives the rotation of the second bevel gear 504, thereby driving the rotation of the first bevel gear 501 and the soot blowing pipe 15. At the same time, when the first bevel gear 501 rotates, it drives the third bevel gear 603 and the rotating shaft 602 to rotate, and then drives the gear 604 to rotate, so that the gear 604 rolls on the second rack 607, thereby pushing the moving plate 14 to move along the guide rod 13 in the direction close to the industrial equipment 1, and drives the soot blowing pipe 15 to move synchronously. At the same time, the soot blowing pipe 15 is driven to rotate through the first driving mechanism 5, and high-temperature steam is supplied through the air supply pipe 17. After the high-temperature steam enters the soot blowing pipe 15, it is sprayed out through the first spray hole 16, so that the inner wall of the industrial equipment 1 can be soot-blown and cleaned;

[0038] When the first push rod 301 abuts against the end of the industrial equipment 1 away from the U-shaped frame 11, the moving rod 202 is pushed to move into the sootblowing pipe 15. At the same time, the fixed ring 203 is deformed, and the moving plate 20 and the moving sleeve 21 are driven to move, so that the circular hole 22 is staggered with the first spray hole 16. The first spray hole 16 and the third spray hole 19 are blocked and sealed by the moving sleeve 21, and the second spray hole 18 is opened. At this time, the high-temperature steam is blown obliquely toward the end of the industrial equipment 1 through the second spray hole 18. Then, through the second drive The moving mechanism 6 enables the moving plate 14 and the soot blowing pipe 15 to move and reset in the direction close to the U-shaped frame 11. When the first push rod 301 is separated from the end of the industrial equipment 1, the moving plate 20 and the moving sleeve 21 can move and reset under the action of the first spring 204, so that the circular hole 22 is aligned with the first spray hole 16. At the same time, the third spray hole 19 and the second spray hole 18 are blocked and sealed by the moving sleeve 21. At this time, the high-temperature steam is sprayed through the circular hole 22 and the first spray hole 16 to perform soot blowing operation on the inner wall of the industrial equipment 1;

[0039] When the second inclined surface 1006 abuts against the fourth push rod 1002, the moving frame 605 is pushed to move toward the fourth connecting block 701, so that the second rack 607 is disengaged from the gear 604, and the first rack 606 is meshed with the gear 604. At this time, the moving plate 14 can be pushed to move along the guide rod 13 in a direction away from the industrial equipment 1, and the soot blowing pipe 15 is driven to move synchronously;

[0040] When the second push rod 302 abuts against one end of the industrial equipment 1 close to the U-shaped frame 11, the first push rod 301 and the moving rod 202 drive the moving plate 20 and the moving sleeve 21 to move away from the U-shaped block 201. At the same time, the first spring 204 is deformed, so that the circular hole 22 is offset from the first spray hole 16, the second spray hole 18 and the first spray hole 16 are blocked and sealed by the moving sleeve 21, and the third spray hole 19 is opened. At this time, high-temperature steam is blown toward the end of the industrial equipment 1 through the third spray hole 19, and so on and so forth, which facilitates the soot blowing operation on the end of the industrial equipment 1, so that the soot blowing efficiency is higher, the effect is better, and the utilization rate of the high-temperature steam is improved;

[0041] When the first inclined surface 1004 abuts against the third push rod 1001, the moving frame 605 is pushed to move in a direction away from the fourth connecting block 701, so that the first rack 606 is disengaged from the gear 604, and the second rack 607 is meshed with the gear 604. At this time, the moving plate 14 and the soot blowing pipe 15 can be pushed to move in a direction close to the industrial equipment 1, and so on. The soot blowing pipe 15 can be reciprocated without the motor 503 rotating forward or reversely, which can reduce damage to the motor 503 and ensure its use effect and life.

[0042] After the soot blowing is completed, the soot blowing pipe 15 is driven by the second driving mechanism 6 to move toward the direction close to the U-shaped frame 11. When the protective cover 23 abuts against the end of the industrial equipment 1, the protective cover 23 is pushed to move toward the direction close to the U-shaped block 201, and the first spray hole 16, the second spray hole 18 and the third spray hole 19 are gradually blocked and sealed. At the same time, the second spring 404 is compressed, thereby avoiding the blockage of the first spray hole 16, the second spray hole 18 and the third spray hole 19, thereby ensuring the efficiency and effect of the subsequent soot blowing;

[0043] Furthermore, when the moving frame 605 moves, the limit pin 803 slides out from one of the limit holes 801 and slides on the side wall of the moving frame 605. At the same time, the third spring 903 is compressed. After the moving frame 605 is moved, under the action of the third spring 903, the limit pin 803 is inserted into another limit hole 801 for limiting, which is more stable and reliable.
