Description

Technical Field

[0001] This utility model belongs to the field of refractory brick technology, and in particular relates to a modular combined refractory brick structure for coke oven carbonization chambers. Background Technology

[0002] The coke oven carbonization chamber is the core part of the coking process used to heat coal to a high temperature, causing it to pyrolyze and transform into coke. The coke oven carbonization chamber is typically constructed of refractory bricks, capable of withstanding high temperatures and effectively isolating the coal from the external environment. Its main function is to provide a sealed, high-temperature environment where the coal undergoes a pyrolysis reaction during heating, producing byproducts such as coke, coal gas, and coal tar.

[0003] A utility model patent application with publication number CN214308176U discloses a modular refractory brick, including a refractory brick body. A snap-fit ​​block is cast on one side of the surface wall of the refractory brick body. A skeleton is embedded inside the refractory brick body. One end of the skeleton extends along the length direction into the snap-fit ​​block. The skeleton embedded inside the refractory brick improves the strength of the refractory brick. At the same time, when the refractory brick is impacted by an external force, multiple refractory bricks are spliced ​​together and connected to a limiting rod inserted into a first limiting hole and a second limiting hole, so that the external impact force can be diffused to multiple refractory bricks, thereby improving the overall support strength of the refractory brick and extending its service life.

[0004] While the above technical solutions enhance the overall strength of refractory bricks, the refractory bricks are connected as a whole by threaded limiting rods. If a part of the brick is damaged, the entire unit needs to be removed to replace the damaged brick. The built-in threaded limiting rods are not easy to remove, making it difficult to replace the damaged brick. To address this issue, we provide a modular combined refractory brick structure for the coke oven carbonization chamber. Utility Model Content

[0005] The purpose of this utility model is to provide a modular combination refractory brick structure for the coke oven carbonization chamber. Through the cooperation of the limiting mechanism and the snap-fit ​​mechanism, it solves the problem in the prior art that the refractory brick structure is formed into a whole by the threaded limiting rod, and it is difficult to remove the threaded limiting rod when it is damaged, which increases the difficulty of replacing the brick.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.
