Embodiment Construction

[0018] Below in conjunction with accompanying drawing, the present invention is further described:

[0019] see figure 1 and figure 2 , a deflector for the expansion gap of a non-metallic expansion joint, including a steel plate 1, L-shaped steel bars 6, tie bars 5 and corundum mullite self-flowing castable; the steel plate 1 is a steel plate with a groove, and the bottom of the groove is poured There are corundum mullite self-flowing castables; several L-shaped steel bars 6 are welded across and arranged above the groove, and are parallel to each other; several tie bars 5 are vertically welded on the L-shaped steel bars 6 to form a steel mesh; the steel mesh is poured Corundum mullite self-flowing castable, an expansion gap is formed between the steel mesh and the groove.

[0020] A number of V-shaped nails 2 are welded on the bottom of the groove and the tie bars 5 , the V-shaped nails 2 are evenly arranged, and the corundum mullite self-flowing castable is poured togethe...

Abstract

A fairing for a nonmetal expansion joint expansion gap comprises a steel plate, L-shaped steel bars, pull ribs and corundum mullite self-flowing type castable. The steel plate is provided with a groove, and the corundum mullite self-flowing type castable is poured into the bottom of the groove. The multiple L-shaped steel bars are welded to the upper portion of the groove in a crossing manner and are parallel to one another. The multiple pull ribs are vertically welded to the L-shaped steel bars, and a reinforcing mesh is formed. The corundum mullite self-flowing type castable is poured into the reinforcing mesh, and the expansion gap is formed. A segmented flow guiding steel plate is transformed into the L-shaped integral castable fairing, fairing deformation caused by steel plate deformation can be eliminated, and hot smoke can be prevented from hollowing out heat preservation cotton.

Description

technical field [0001] The invention belongs to the technical field of expansion systems of power plant boilers, and in particular relates to a guide cover for expansion gaps of non-metallic expansion joints. Background technique [0002] The size of the non-metallic expansion joint of the air-smoke system of the utility boiler is large, and the expansion error of the expansion joint is relatively large during the infrastructure installation period, resulting in insufficient expansion compensation design margin, and the working environment of the expansion joint of the air-smoke system is very bad when the boiler is in normal operation, resulting in The non-metallic expansion joints of boilers often suffer from severe distortion, ash leakage, and spark accidents during normal operation. Since most of the non-metallic expansion joints of the boiler body are installed at high altitudes, it is very difficult to deal with accidents, and it is difficult to cure them. Stop the furn...
