Description

Technical Field

[0001] This utility model relates to the field of coke technology, specifically to an air inlet brick installation structure. Background Technology

[0002] The air inlet brick (also known as the primary air inlet brick or coke oven tuyer brick) is a key refractory component on the side wall of the coke oven carbonization chamber. It is mainly used to control the flow rate and direction of air (or gas) entering the carbonization chamber, thereby affecting the combustion and coking process of coke.

[0003] Traditionally used primary air inlet bricks are cylindrical through-hole bricks with a vertical through-hole direction, which are square on the outside and round on the inside. When air enters the carbonization chamber, due to the negative pressure inside the furnace, a large amount of air directly impacts the surface of the coke, causing a large amount of coke below the primary air inlet to overfire, resulting in severe coking and a decrease in its quality and production capacity. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an air inlet brick installation structure that solves the problem of traditional primary air inlet bricks, which are cylindrical through-hole bricks with vertical through-holes (square on the outside and round on the inside). When air enters the carbonization chamber, due to the negative pressure inside the furnace, a large amount of air directly impacts the surface of the coke, causing a large amount of coke below the primary air inlet to overfire, resulting in severe coking and a decrease in quality and production capacity.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: an air inlet brick installation structure, including an installation cylinder, wherein the air inlet brick body is movably sleeved in the inner cavity of the installation cylinder, and the surface of the air inlet brick body is symmetrically provided with side through holes.

[0006] Preferably, the side through hole is a circular hole with a diameter of φ50*φ50.

[0007] Preferably, the inner cavity of the mounting cylinder and the port of the air inlet brick body are both T-shaped and mutually compatible.

[0008] This utility model provides an air inlet brick installation structure. Compared with the prior art, it has the following advantages: 1. This air inlet brick, by changing the vertical flow direction of the air inlet brick body to lateral flow, makes it evenly distributed throughout the carbonization chamber, improving the severe coking phenomenon, increasing production capacity and reducing production costs.

[0009] 2. The air inlet brick, through the assembly of the mounting cylinder and the air inlet brick body, allows the air inlet brick body to be selected and its direction adjusted by tools inside the mounting cylinder. In addition, if the air inlet brick body is damaged during long-term use, it can be directly removed from the mounting cylinder by tools for easy replacement. Attached Figure Description

[0010] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a cross-sectional view of the structure of this utility model; Figure 3 This is a schematic diagram of the structural air vent brick of this utility model.

[0011] In the diagram: 1. Mounting cylinder; 2. Air inlet brick body; 3. Side through hole. Detailed Implementation

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figures 1-3 This utility model provides a technical solution: an air inlet brick installation structure, including an installation cylinder 1, an air inlet brick body 2 is movably sleeved in the inner cavity of the installation cylinder 1, and the surface of the air inlet brick body 2 is symmetrically provided with side through holes 3. The airflow direction of the vertical straight flow of the air inlet brick body 2 is changed to lateral flow through the side through holes 3, so that it is evenly distributed in the entire carbonization chamber, improving the phenomenon of severe coking, increasing production capacity and reducing production costs.

[0014] Side through hole 3 is a φ50*φ50 round hole; The fire resistance of the bricks in the installation cylinder 1 and the air inlet brick body 2 must be ≥1700℃; Flexural strength: ≥ 6MPa at 110℃ for 24h, ≥ 8MPa at 1100℃ for 3h; Compressive strength: ≥ 50MPa at 110℃ for 24 hours, ≥ 60MPa at 1100℃ for 3 hours; Changes in reheat line: 1100℃ x 3h ± 0.2% Thermal shock stability: >35 cycles; Brick density: 2.4~2.6 g / cm³.

[0015] The inner cavity of the mounting cylinder 1 and the port of the air inlet brick body 2 are both T-shaped and compatible. The T-shape allows the air inlet brick body 2 to fit snugly into the inner cavity of the mounting cylinder 1 without falling off. In addition, through the assembly of the mounting cylinder 1 and the air inlet brick body 2, the air inlet brick body 2 can be selected and its direction adjusted by using a tool in the inner cavity of the mounting cylinder 1. Furthermore, if the air inlet brick body 2 is damaged during long-term use, it can be directly removed from the mounting cylinder 1 by using a tool for easy replacement.

[0016] During operation or use, first install the mounting cylinder 1 on the coke oven, then fit the air inlet brick body 2 into the inner cavity of the mounting cylinder 1, and use a tool to press against the inner wall of the air inlet brick body 2, thereby driving the air inlet brick body 2 to rotate in the inner cavity of the mounting cylinder 1, thus achieving directional adjustment. Secondly, the side through hole 3 sets the air inlet brick body 2 to change the vertical straight airflow direction to lateral flow, so that it is evenly distributed throughout the carbonization chamber, improving the phenomenon of severe coking, increasing production capacity and reducing production costs. Finally, when the air inlet brick body 2 is damaged during long-term use, it can be directly replaced.

[0017] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, the phrase "comprising an element defined as..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0018] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
