Description

Technical Field

[0001] The utility model relates to the technical field of coke oven maintenance, in particular to a coke oven brick gas channel dredging tool. Background Art

[0002] During the production process of the coke oven, as the age of the furnace increases, the wall of the carbonization chamber wears and erodes, and the furnace wall leaks to varying degrees. Therefore, the furnace wall leaking lamp bricks in the vertical fire channel of the combustion chamber are prone to melting, which in turn forms dead eyes and affects normal heating and stable production order. In order to stabilize the heating of the coke oven and improve the quality of coke, it is necessary to dredge the combustion chamber brick gas channel. Traditional dredging methods include dredging with 12# threaded steel bars and dredging with holes in the furnace wall. The steel bar dredging method uses relatively long steel bars, and the temperature of the upper part of the brick gas channel is high, which makes it difficult to dredge the melting vertical fire channel. The disadvantage of dredging by digging and patching the carbon flower chamber is that it damages the furnace wall and the workload is large, which affects the coke output. Utility Model Content

[0021] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0022] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0023] For ease of description, spatial relative terms such as "upper," "lower," "left," and "right" may be used herein to describe the relationship of one element or feature shown in a figure relative to another element or feature. It should be understood that the spatial terms are intended to include different orientations of the device in use or operation in addition to the orientation shown in the figures. For example, if the device in the figure is inverted, elements described as being "below" other elements or features will be positioned "above" the other elements or features. Thus, the exemplary term "below" may include both upper and lower orientations.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention.
