AI Technical Summary

Technical Problem

When disassembling the blowpipe of the blast furnace blast system, the blowpipe end may slide out rapidly, causing deformation or damage. Furthermore, immersing it in water after disassembly may reduce the strength of the refractory material, potentially leading to an accident.

Method used

Design a buffer device including a placement plate, a short support rod, a long support rod, and a buffer pad. The placement plate has an angle of 25°-30° with the horizontal line and is used to buffer and support the blowpipe end. A baffle is set to prevent slippage, and the buffer pad reduces rigid collisions. The structure is reasonably designed and easy to operate on site.

Benefits of technology

It effectively protects the blowpipe tip, prevents deformation and damage, extends service life, reduces drop height, reduces impact force, improves operational safety, and reduces safety accidents.

Abstract

This utility model discloses a buffer device for disassembling blast furnace blowpipes, comprising a placement plate with a short support rod and a long support rod fixedly connected to its bottom surface. The angle between the placement plate and the horizontal line is 25°–30°. A buffer pad is fixedly connected to the surface of the placement plate. The advantages of this utility model are: reasonable structural design, small size, easy processing, low manufacturing cost, convenient on-site operation, easy handling, and more flexible use. After disassembling the blowpipes of the blast furnace air supply system, the end of the blowpipe can be placed on the surface of the buffer device, which can protect the end of the blowpipe, preventing it from slipping out of the air supply system's main sleeve, causing collision damage to the blowpipe end, and reducing the service life of the blowpipe.
