Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of coke oven wall welding repair, in particular to coke oven joint inner supporting bricks. Background Art
[0002] Clean heat recovery coke ovens operate at negative pressure during production. The high-temperature exhaust gas after combustion in the coke oven passes through the rising fire channel on the main wall and the rising diversion pipe and is collected in the gas collecting pipe to enter the waste heat boiler for power generation. Therefore, the rising bridge pipe used for rising diversion is the hottest part of the entire heat recovery coke oven, with a temperature of 1300℃-1350℃. In addition, the heat wave airflow is rapid. The rapid high-temperature airflow not only has a strong impact on the wall of the coke oven riser diversion pipe, but the high-speed gas also causes serious erosion of the pipe wall.
[0003] However, the patents in the prior art have the following disadvantages:
[0004] The connection between the head brick and the furnace brick is seriously damaged. Most of the side surfaces of the head brick are worn flat, which cannot cause the new brick to bite. After the new bricks are laid, straight joints are formed. When the temperature rises, damage and leakage are very likely to occur here, resulting in unsatisfactory results after masonry. Utility Model Content
[0005] The technical problem to be solved by the present invention is to overcome the above technical defects and provide a support and repair device that can enhance the strength of new masonry and avoid leakage.
[0006] In order to solve the above problems, the technical solution of the utility model is: the internal support bricks of the coke oven joint include support brick one and support brick two, the support brick one and support brick two are both U-shaped structures, and their inner side walls are provided with rounded corners, the length of the side walls of the support brick one is less than the length of the side walls of the support brick two, and the support brick one and support brick two are stacked up and down when working, and staggered, thereby increasing the internal support of the coke oven joint and increasing stability.
[0007] Furthermore, the supporting brick 1 and the supporting brick 2 are both made of high-purity quartz material and cast, which is a zero-expansion material.
[0008] Furthermore, the side walls of the supporting brick 1 can be 350 mm in length, 100 mm in height, and 250 mm in width. The above specifications can be adjusted according to the actual size of the coke oven. The side walls of the supporting brick 1 are 30 mm thick.
[0009] Furthermore, the side walls of the supporting brick 2 can be 440 mm in length, 100 mm in height, and 250 mm in width. The above specifications can be adjusted according to the actual size of the coke oven. The side walls of the supporting brick 2 are 30 mm thick.
[0010] The advantages of this utility model compared with the existing technology are:
[0011] The utility model utilizes supporting bricks one and two, utilizes high-purity quartz material, utilizes supporting bricks one and two to be stacked on each other, and is staggered, thus can increase the strength of new masonry, solve the problem of leakage at the connection, and ensure the firmness. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 It is a three-dimensional diagram of the use status of the supporting bricks in the coke oven joint of the utility model.
[0013] Figure 2 It is a three-dimensional diagram of the supporting bricks in the coke oven joint of the utility model.
[0014] As shown in the figure: 1. Support brick one; 2. Support brick two. DETAILED DESCRIPTION
[0015] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings, wherein the same components are represented by the same reference numerals.
[0016] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the accompanying drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.
[0017] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.
[0018] like Figures 1 to 2 As shown, the inner supporting bricks of the coke oven joint include supporting brick 1 and supporting brick 2. The supporting brick 1 and supporting brick 2 are both made of high-purity quartz material and cast, which is a zero-expansion material. The supporting brick 1 and supporting brick 2 are both U-shaped structures, and their inner side walls are provided with rounded corners. The length of the side walls of the supporting brick 1 is smaller than the length of the side walls of the supporting brick 2. The supporting brick 1 and supporting brick 2 are stacked up and down when in action, and staggered in distribution, thereby increasing the internal support of the coke oven joint and increasing stability.
[0019] like Figure 1 and Figure 2As shown, in implementation, the side walls of the supporting brick 1 can be 350 mm in length, 100 mm in height, and 250 mm in width. The side walls of the supporting brick 1 are 30 mm in thickness. The side walls of the supporting brick 2 are 440 mm in length, 100 mm in height, and 250 mm in width. The side walls of the supporting brick 2 are 30 mm in thickness. The above specifications can be adjusted according to the actual size of the coke oven.
[0020] In specific use, such as Figure 1 and Figure 2 As shown, first, support brick 1 and support brick 2 are made of high-purity quartz material. The different lengths of the side walls of support brick 1 and support brick 2 can be spliced and stacked up and down. When stacking, support brick 1 and support brick 2 can be staggered to increase stability. In this way, they can be supported in the furnace joint, thereby increasing strength and being more convenient to use.
[0021] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
