Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to a series expansion joint for balancing thermal stress in an incinerator. Background Technology

[0002] In high-temperature industrial equipment such as incinerators, drastic temperature changes cause structural materials to expand and contract, generating thermal stress. If left uncontrolled, this thermal stress can lead to equipment damage, failure, or even safety accidents. Therefore, researchers are constantly exploring new designs to alleviate these problems. The series expansion joint utilizes a design concept of connecting multiple expansion joints. These expansion joints can move relative to each other when the temperature changes, thereby effectively dispersing thermal stress. The flexible connection of each expansion joint allows it to adapt to different temperature changes and avoid stress concentration. In this way, the overall structural durability is significantly improved, and the safety and service life of the incinerator are extended accordingly.

[0003] However, existing series expansion joints for balancing thermal stress in incinerators have the following drawbacks:

[0004] (1) At present, due to the rigidity of the overall structure of the device, it is difficult to effectively disperse thermal stress when thermal stress occurs, which exacerbates the damage to the equipment.

[0005] (2) At present, because the corrugated pipe is relatively soft and exposed to the outside for a long time, it is easily damaged by the outside world and its service life is reduced. Utility Model Content
