Benefits of technology

The inventor's new type of union allows it to move backward or forth without losing its effectiveness over longer periods due to friction between materials caused by thermal cycling during operation. This makes sure there are no damaging changes on any part inside the system even if they happen repeatedly.

Problems solved by technology

This patented technical problem addressed by the inventors relates to improving the durability of expandable joints used for absorbing changes caused during operation at higher temperatures within the smelting process' equipment (Furnaces). These joints can become worn out or lose their effectiveness over time because they have been designed without sufficient consideration given how these structures were damaged when subjected to repeated stress cycles.

Embodiment Construction

[0020] Such as figure 1 As shown, the water-cooled non-metallic expansion joint of the present invention includes a water-cooled wall 100, an upper metal frame 200, a lower metal frame 300, a movable metal frame 400, two-stage castables 500, a thermal insulation sleeve 600, a telescopic sleeve 700 and a dustproof Circle 800.

[0021] Wherein the water wall 100 is bent into " ”-shaped carbon steel small-diameter seamless steel pipe 101 is surrounded, and the carbon steel small-diameter seamless steel pipe 101 is welded through ribs, so that the water-cooled wall 100 has a first cylindrical wall 102 and is located outside the upper end of the first cylindrical wall 102 The first annular end plate 103 and the annular outer wall 104 outside the annular end plate, and the two ends of the water wall 100, that is, the lower end of the first cylindrical wall 102 and the lower end of the annular outer wall 104 are connected with each carbon Ring-shaped water collection tanks 105 and...

Abstract

The invention discloses a water-cooled nonmetal expansion joint, which comprises a water-cooled wall, an upper metal frame, a lower metal frame, a flexible metal rack, two sections of pouring material, an insulation jacket and a flexible sleeve, wherein the water-cooled wall is formed by annularly welding bent small-diameter steel pipes so as to form a first cylindrical wall and a first annular end plate outside the upper end of the first cylindrical wall; the upper metal frame is provided with an axial interlayer having a downwards opening; the lower metal frame and the water-cooled wall form an radial interlayer; and the flexible metal rack is arranged in the axial interlayer and the radial interlayer. The water-cooled nonmetal expansion joint has the advantages of being capable of efficiently absorbing the three-directional displacement of a furnace smoke pipe and ensuring the long-term reliable work of the inner wear-resisting waterproof materials and the insulation jacket after absorbing the three-directional displacement.
