Expansion joint for high-temperature feed bin

Abstract

The invention belongs to the technical field of high-temperature silo design, and specifically relates to a high-temperature silo expansion joint, which includes: an inner elastic component, a connecting body and an outer elastic sheet, wherein the inner elastic assembly includes: a connecting support plate and an inner elastic sheet, Both ends of the connecting support plate are respectively connected to the upper and lower walls of the high-temperature silo, a supporting opening is provided in the middle of the connecting supporting plate, and the supporting opening extends horizontally to the Inside the high-temperature silo, the inner elastic sheet is arranged in the support opening; one end of the connecting body is connected to the connecting support plate and communicates with the support opening, and the other end is provided with the outer elastic sheet . The present invention releases the stress generated by the deformation of the high-temperature silo through the inner elastic sheet and the outer elastic sheet arranged inside and outside the silo, improves the thermal expansion and contraction resistance and the overall stability of the high-temperature silo, thereby improving the high-temperature The service life of the silo.

Description

technical field [0001] The invention belongs to the technical field of high-temperature silo design, and in particular relates to an expansion joint of a high-temperature silo. Background technique [0002] Common expansion joints are customarily also called compensators, or expansion joints, which are composed of bellows (an elastic element) that constitutes the main body of its work and accessories such as end pipes, brackets, flanges, and conduits. The expansion joint is a flexible structure arranged on the container shell or pipeline in order to compensate the additional stress caused by temperature difference and mechanical vibration. Utilize the effective telescopic deformation of the bellows of its working body to absorb the dimensional changes of pipelines, conduits, containers, etc. caused by thermal expansion and contraction, or compensate for the axial, lateral and angular displacement of pipelines, conduits, containers, etc.; It can also be used for noise reduct...

AI Technical Summary

Problems solved by technology

However, most of the silos are only for high temperature treatment. While bearing the high temperature, the added high temperature resistant layer and insulation layer will cause inconsistent expansion and contraction of the steel structure of the silo and the high temperature resistant layer due to the thermal expansion and contraction of the silo, thus Stress is generated and the silo is damaged. The expansion of the high-temperature silo is not synchronized, which will affect the sealing of the equipment, and the leakage of combustible gas in the silo will pose a safety hazard.
