Example Embodiment

[0020] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings:

[0021] like figure 1 As shown in the figure, the present invention is a corbel structure in the chute area of ​​the CDQ, and the corbel structure is made of multi-layer corbel bricks 2; such as Figure 2-Figure 4 As shown, there are several supports 4 between adjacent 2-layer corbel bricks 2, the support 4 is a hard support, and its thickness is the same as the thickness of the ash joint 3, and the top surface of the support 4 is the same as the upper corbel brick. Direct contact, the bottom surface of the support 4 is in direct contact with the lower corbel brick.

[0022] The thickness of the support member 4 is 2-5mm, and is divided into various specifications according to the thickness, and the support member 4 of the corresponding thickness is selected according to the elevation of different corbel brick layers.

[0023] The support m...

Abstract

The invention relates to a bracket structure for a chute area of a dry quenching furnace. The bracket structure is formed by building a plurality of layers of bracket bricks; and a plurality of supporting pieces are arranged between every two adjacent layers of bracket bricks, the supporting pieces are hard supporting pieces, the thickness of the supporting pieces is the same as that of mortar joints, the top faces of the supporting pieces make direct contact with the upper layer of bracket bricks, and the bottom faces of the supporting pieces make direct contact with the lower layer of bracket bricks. The supporting pieces are placed in the refractory mortar joints between the bracket brick layers, so that the problems of sinking of the annular air duct and cracking of the chute partition wall caused by deformation of the bracket mortar joints and inaccurate bracket elevation control are effectively prevented, the masonry quality of the dry quenching furnace is improved, and the service life of the dry quenching furnace is prolonged.

Description

technical field [0001] The invention relates to the technical field of dry quenching coke ovens, in particular to a corbel structure of a chute area of ​​a dry quenching coke oven. Background technique [0002] Dry quenching has the functions of saving energy and reducing consumption, protecting the environment and improving the quality of coke, and has been widely used in recent years. CDQ coke oven is the key equipment of CDQ technology. It includes pre-storage area, annular air channel area, chute area and cooling area from top to bottom. Among them, the corbel of chute area 1 is made of multi-layer corbel bricks. 2 masonry (such as figure 1 shown), which is an important structure supporting the inner ring wall of the CDQ oven. In actual production, the corbel is easily worn, cracked or even collapsed due to heavy load-bearing, frequent operating temperature fluctuations, and long-term scouring by high-temperature coke and high-temperature circulating airflow containing...
