Description

Technical Field

[0001] This utility model belongs to the technical field of pulverizing systems, and specifically relates to a corrugated compensator for pulverizing systems. Background Technology

[0002] Corrugated compensators are commonly used in pulverizing systems at the outlet of coal mills, the inlet of burners, or in the vertical or horizontal positions of long-distance pulverized coal conveying pipelines for damping, noise reduction, vibration reduction, and displacement compensation. The commonly used corrugated compensators in pulverized coal pipelines of pulverizing systems are single-corrugated metal compensators with a Q235 base material and a 2mm thick corrugated section made of Q235 material pressed and welded together. Commonly used single-corrugated compensators have disadvantages such as poor resistance to erosion and wear, short service life, poor vibration reduction and displacement compensation effects, frequent replacement requiring significant workload, and high operational risks. In particular, when applied in pulverizing systems, the small particles carried in the pipeline can easily cause significant erosion of the single-corrugated metal compensator, affecting its service life. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a corrugated compensator for a pulverizing system, which solves the problems of poor erosion and wear resistance, short service life, and poor vibration reduction and displacement compensation effect of existing single corrugated compensators. This utility model patent designs a corrugated compensator for a pulverizing system that is not only simple in structure, widely available in materials, and simple in manufacturing process, but also has significant vibration reduction and displacement compensation effects. Its erosion and wear resistance and service life can be extended by 3-5 times compared with single corrugated compensators.

[0004] This utility model discloses a corrugated compensator for a pulverizing system, comprising a first tube body, a second tube body, a corrugated compensating tube, a first ceramic ring, a second ceramic ring, a third ceramic ring, and a wear-resistant weld overlay layer. The ports of the first tube body and the second tube body are spaced apart to form a gap between them. The two ends of the corrugated compensating tube are respectively welded to the outer walls of the first tube body and the second tube body. The first ceramic ring is fixed to the inner wall of the port of the first tube body near the gap by using high-temperature ceramic adhesive. The second ceramic ring is fixed to the inner wall of the port of the second tube body near the gap by using high-temperature ceramic adhesive. The third ceramic ring is disposed in the corrugated compensating tube directly opposite the gap. The wear-resistant weld overlay layer is located on the inner wall of the second tube body and is located on the side of the third ceramic ring away from the gap.

[0005] Furthermore, the corrugated compensation pipe is provided with two corrugated rings.

[0006] Furthermore, the thickness of the wear-resistant weld overlay is equal to that of the third ceramic ring.

[0007] Furthermore, the first tube body, the second tube body, and the corrugated compensation tube are all made of stainless steel.

[0008] This pulverizing system uses a corrugated compensator with a first ceramic ring, a second ceramic ring, and a third ceramic ring respectively installed on the first pipe body, the gap position, and the second pipe body. This effectively improves the wear resistance of the corrugated compensator. Furthermore, when the corrugated compensator is in use, the airflow medium flows from the second pipe body to the first pipe body. To prevent the high-temperature hot air from damaging the high-temperature ceramic adhesive of the third ceramic ring and affecting its bonding performance, a wear-resistant weld overlay layer protects the joint of the third ceramic ring and the high-temperature ceramic adhesive within it. This also ensures the flatness and smoothness of the internal channels of the double corrugated compensator, thereby ensuring the smoothness and uniformity of the internal medium flow.

[0011] This utility model discloses a corrugated compensator for a pulverizing system, which is not only simple in structure, widely available in materials, and easy to manufacture, but also has significant vibration reduction and displacement compensation effects. Its resistance to erosion and wear and its service life can be extended by 3-5 times compared with a single corrugated compensator.

The ports of the first tube body 1 and the second tube body 4 are spaced apart to form a gap 6 between them. The two ends of the corrugated compensating tube 3 are respectively welded to the outer walls of the first tube body 1 and the second tube body 4. The first ceramic ring 5 is fixed to the inner wall of the port of the first tube body 1 near the gap 6 by using high-temperature ceramic adhesive. The second ceramic ring 2 is fixed to the inner wall of the port of the second tube body 4 near the gap 6 by using high-temperature ceramic adhesive. The third ceramic ring 7 is disposed in the corrugated compensating tube 3 directly opposite the gap 6. The wear-resistant weld overlay layer 8 is located on the inner wall of the second tube body 4, and the wear-resistant weld overlay layer 8 is located on the side of the third ceramic ring 7 away from the gap 6.
