Description

Technical Field

[0001] This utility model belongs to the technical field of coke oven equipment, and specifically relates to a novel coke oven column. Background Technology

[0002] The coke oven column is a primary protective iron component, erected on the outside of the combustion chamber protective plate on both sides of the coke oven machine and coke oven. Its inner surface is close to the outer protective plate of the furnace head bricks on both sides of the coke oven combustion chamber, and is pressed against the protective plate by a spring-loaded set screw. Figure 1 and Figure 2 As shown, the bottom of the furnace column is connected to the corbel of the foundation top plate side beam at the bottom of the coke oven via foundation bolts and lower horizontal tie bars. The middle section is pressed against the furnace body bricks from bottom to top by multiple spring devices. The upper end is connected to the machine and coke side furnace columns as a whole by upper horizontal tie bars. In this way, the tie bars and springs on the entire coke oven machine and coke side furnace columns work together to pressurize and protect the coke oven, preventing deformation and leakage caused by thermal expansion and widening of the brick joints under long-term hot operation. The protection of the furnace column ensures stable operation of the coke oven and extends the service life of the coke oven masonry.

[0003] The existing furnace columns are H-shaped cross-section furnace columns. They have the following three shortcomings: 1. [The text abruptly ends here, likely due to an incomplete sentence or missing information.] Figure 2 As shown, multi-line springs are installed on the furnace column to apply protective pressure to the furnace plate. The springs are distributed in pairs on both sides of the web, are numerous, have great force, and require significant adjustment and strength, making them inconvenient to use. 2. Because the furnace column has multiple line springs to provide protective force for the coke oven, it needs high stability. High bending resistance allows the furnace column to maintain its shape stability under the spring reaction force. As the size of the coke oven increases, the required protective load also increases. Simply increasing the web height of the H-shaped furnace column to improve bending resistance (see...) Figure 3 The L-shaped structure will increase the distance between the furnace column and the coke oven centerline, causing the installation and positioning of external equipment to spread outwards and occupy more planar layout space, making the installation space for coke oven equipment even more cramped; 3. Figure 1 As shown, the furnace column is installed above the corbel of the side beam of the bottom civil engineering foundation of the coke oven. The bolt holes at the anchor bolts are elongated oval holes of length L, allowing the furnace column position to vary within this range, resulting in a sliding connection between the furnace column and the corbel. After cold installation, under the conditions of thermal expansion and deformation during oven baking, the furnace column base plate and the corbel slide relative to each other, causing displacement until the furnace body reaches the position under normal production conditions. The movement of the furnace column will increase the impact on the system connection. 4. Each set of spring devices arranged above the operating platform is equipped with a separate protective cover to isolate the influence of the production environment and provide dedicated protection for the springs. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of coke oven column, which can improve the stability of the column body and comprehensively improve the shortcomings of existing columns.

[0005] To achieve the above objectives, the present invention provides a novel coke oven column, comprising a column body.

[0006] The bottom of the furnace column body is rigidly fixed to the coke oven bracket; the furnace column body includes two wing plates and two web plates, with the two web plates fixed between the two wing plates; the cross-section of the furnace column body is a box-shaped cross-section, and a box-shaped cavity is formed inside the box-shaped cross-section.

[0007] Several spring pressurization devices are installed at the center of the furnace column body; each spring pressurization device includes a spring body and a top screw, the spring body is horizontally arranged in the box-shaped cavity; the top screw is located at one end of the spring body; the end of the top screw away from the spring body extends outward through the wing plate.

[0008] Preferably, the bottom of the furnace column body is inverted "L" shape; the bottom of the furnace column body is located at the top and side of the coke oven bracket, and is rigidly connected to the side of the coke oven bracket by a lower horizontal tie bar; the bottom of the coke oven bracket is provided with a connecting angle steel; the connecting angle steel is fixedly connected to the furnace column body by a bolt assembly.

[0009] Preferably, the spring pressing device further includes a first spring seat, a second spring seat, and a screw, wherein the first spring seat and the second spring seat are both horizontally arranged in the box-shaped cavity; the spring body is installed between the first spring seat and the second spring seat; one end of the screw is threadedly connected to the first spring seat, and the other end extends toward the side of the first spring seat away from the second spring seat; a positioning seat is provided at the end of the screw away from the second spring seat; the positioning seat is arranged in the box-shaped cavity.

[0010] Preferably, the end of the screw away from the first spring seat is provided with a limiting section; the diameter of the limiting section is smaller than the diameter of the screw, and the limiting section passes through the positioning seat; the wing plate closer to the positioning seat among the two wing plates is provided with an adjustment hole; the adjustment hole corresponds to the limiting section.

[0011] Preferably, the end of the limiting segment away from the screw is a prism segment.

[0012] This utility model discloses a novel coke oven column, which has the following advantages compared with the prior art:

[0013] 1. The position of the furnace column body after installation remains fixed, resulting in higher system stability: First, the furnace column body rests on the upper surface of the corbel on the side beam of the foundation top plate during installation, ensuring that all furnace columns are positioned at the same height, and the point of application of the spring protection force is consistent. There are two rigid fixed connections on the side and bottom of the corbel, increasing the stability of the furnace column bottom and ensuring that all furnace columns are positioned at the same center. The distance between the furnace column and the center line of the coke oven remains stable, and the furnace column does not shift outward. Second, since numerous components and equipment are installed on the furnace column, the fixed position of the furnace column makes the system connection attached to the furnace column more stable. In addition, the furnace column does not move during the entire furnace heating process and production process, and the stress is relatively simple. During this period, the influence of system forces such as friction does not need to be considered when adjusting the spring force of the spring pressure device.

[0014] 2. The furnace column body of this utility model is a box-shaped cross-section furnace column, and the main structure is a box-type structure. Compared with the H-shaped furnace column, the overall cross-section of the furnace column body has higher bending resistance under the same outline dimensions, ensuring the long-term stability of the furnace column body. Furthermore, under the same section coefficient, the outline geometric dimensions of the box-shaped cross-section are smaller, and the smaller web height reduces the column shape of the furnace column body, providing convenience for equipment installation and maintenance, and saving more space for production.

[0015] 3. This utility model furnace column requires fewer spring pressure devices, making it more economical and convenient: The box-section furnace column has two webs, with the spring pressure devices installed inside the box cavity. In contrast, existing H-section furnace columns have a single web, with spring pressure devices installed in pairs on both sides of the web. Compared to existing H-section furnace columns, this utility model box-section furnace column requires half the number of springs for the same cross-section, saving materials and investment, and making installation, adjustment, and replacement more convenient. Furthermore, the spring pressure devices are easier to protect.

[0016] 4. The spring compression device of this utility model is set inside the box-shaped cavity. The relatively closed box-shaped cavity wall plate, namely the web plate and the wing plate, has only a few mounting holes, which isolates the spring device from the external environment and protects the spring body. There is no need to add a spring protection cover device. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 3-4 As shown, a novel coke oven column includes a column body 1.

[0024] The bottom of the furnace column body 1 is rigidly fixedly connected to the coke oven bracket 3; the furnace column body 1 includes two mutually symmetrical flanges 11 and two mutually symmetrical webs 12, with the two webs 12 vertically fixed between the two flanges 11; the cross-section of the furnace column body 1 is a box-shaped cross-section, with a box-shaped cavity 13 formed inside. Compared with an H-shaped furnace column, the overall cross-section of the furnace column body 1 has higher bending resistance under the same profile dimensions, where the profile dimensions are shown in [reference needed]. Figure 3 The B and L sections ensure the long-term stability of the furnace column body 1. Under the same section coefficient, the outline geometry of the box section is smaller. The smaller height of the web 12 reduces the shape of the furnace column body, which facilitates equipment installation and maintenance and saves more space for production.

[0025] like Figure 5 As shown, several spring-pressurizing devices are installed at the center of the furnace column body 1. These devices pressurize the coke oven protection plate, ensuring it adheres tightly to the coke oven body. Each spring-pressurizing device includes a spring body 21 and a top screw 22. The spring body 21 is horizontally positioned within the box-shaped cavity 13, eliminating the need for an additional protective cover. The top screw 22 is located at one end of the spring body 21. The end of the top screw 22 away from the spring body 21 extends outward through the wing plate 11. The top screw 22 on the outer side of the furnace column body 1 presses against the protection plate. When the furnace body expands, the protection plate moves outward with the furnace body, while the top screw 22 moves into the box-shaped cavity 13. The furnace column body 1 is fixedly connected to the coke oven bracket 3 at its bottom. Since the furnace column body 1 remains fixed after installation and does not shift outward, the system exhibits higher stability.

[0026] In this embodiment, the spring pressing device further includes a first spring seat 23, a second spring seat 24, and a screw 25. Both the first spring seat 23 and the second spring seat 24 are horizontally disposed within the box-shaped cavity 13. The spring body 21 is installed between the first spring seat 23 and the second spring seat 24. One end of the screw 25 is threadedly connected to the first spring seat 23, and the other end extends towards the side of the first spring seat 23 away from the second spring seat 24. The screw 25 is coaxial with the set screw 22. A positioning seat 26 is provided at the end of the screw 25 away from the second spring seat 24. The positioning seat 26 is disposed within the box-shaped cavity 13, limiting the screw 25. When rotated... When the screw 25 is in place, the positioning seat 26 limits the screw 25, causing the first spring seat 23 to move on the screw 25, changing the compression of the spring body 21 and thus changing the spring force. One end of the set screw 22 in the box cavity 13 is fixed to the second spring seat 24. When the furnace body expands, the set screw 22 moves into the box cavity 13, causing the second spring seat 24 to move towards the first spring seat 23, compressing the spring body 21. When the spring body 21 is compressed to an excessive deformation, the screw 25 is rotated to move the first spring seat 23, adjusting the spring force within a certain range to ensure that the spring is not overcompressed and that the spring reaction force of the furnace body is not excessive and causes damage to the protective plate.

[0027] In this embodiment, the end of the screw 25 away from the first spring seat 23 is provided with a limiting section 251; the diameter of the limiting section 251 is smaller than the diameter of the screw 25, and the limiting section 251 passes through the positioning seat 26; the wing plate 11 near the positioning seat 26 of the two wing plates 11 is provided with an adjustment hole, wherein the positioning seat 26 can be fitted into the adjustment hole; the adjustment hole corresponds to the limiting section 251, and the limiting section 251 can be rotated through the adjustment hole. When the limiting section 251 rotates, the screw 25 rotates. Since the screw 25 is limited by the spring body 21 and the positioning seat 26, the first spring seat 23 will move.

[0028] In this embodiment, the end of the limiting segment 251 away from the screw 25 is a prism segment 252, which facilitates the loading of tools such as wrenches for operation.

[0029] In this embodiment, as Figure 4 As shown, the bottom of the furnace column body 1 is inverted "L" shape; the bottom of the furnace column body 1 is set at the top and side of the coke oven bracket 3, and is rigidly connected to the side of the coke oven bracket 3 by the lower horizontal tie bar 14; a connecting angle steel 15 is welded to the bottom of the coke oven bracket 3; the connecting angle steel 15 is connected to the furnace column body 1 by bolts 16 and nuts, and the lower horizontal tie bar 14 and the connecting angle steel 15 make the furnace column body 1 rigidly fixed to the bottom and side of the coke oven side beam bracket 3, so that the furnace column body 1 is stably connected and its position remains unchanged throughout its entire life cycle.
