Description

Technical Field

[0001] This application relates to a coke oven protection device, belonging to the field of coke oven technology. Background Technology

[0002] With societal development and increasingly stringent requirements for energy conservation and environmental protection, coke oven protection equipment is undergoing further improvements. Traditional coke oven protection plates employ a single-piece integral casting structure. This type of plate has numerous spring adjustment points, making adjustment difficult. Furthermore, the spring potential energy distribution on the protection plate is uneven. Additionally, during production, the protection plate is continuously subjected to mechanical forces when opening and closing the furnace door, causing uneven stress on the furnace columns and door frame. These factors all contribute to the vulnerability of the protection plate to breakage, thus affecting its lifespan.

[0003] Furthermore, traditional protective plates require anchoring nails to be installed on the inner side and a layer of heat-insulating castable to be applied before installation. After the coke oven ironwork system is fully installed, the oven is baked. When the oven temperature reaches 700℃~750℃, refractory mortar is used to fill the gap between the protective plate and the furnace head a second time. This structure can only achieve good airtightness and heat insulation performance of the coke oven if the refractory mortar grouting is tight. However, grouting is a concealed project, and the grouting effect is difficult to guarantee, resulting in poor furnace body tightness. Moreover, during production, as the furnace body expands, the difference in expansion coefficients between the grout and the furnace bricks causes gaps that reduce the furnace body's sealing performance, leading to a large amount of thermal repair work and consequently affecting the furnace's service life. Utility Model Content

[0004] To address the aforementioned issues, this application proposes a coke oven protection device that can effectively eliminate mechanical stress, prevent the protective plate from bending and deforming during the oven expansion process, and ensure that the protective plate remains in close contact with the oven body. This enhances the oven body's airtightness and heat insulation, thereby effectively extending the coke oven's service life.

A balancing connecting component is disposed within the groove. The several plates are connected by the connecting plate and a portion of the balancing connecting component. The barrier layer is connected to the end of the protective plate away from the connecting plate.

[0008] The second protective part abuts against at least a portion of the connecting plate. The second protective part includes a furnace column and a telescopic assembly, which is disposed opposite to each other on both sides of the furnace column and is at least partially located inside the furnace column.

[0009] Optionally, the groove is filled with castable material, and the balancing connection assembly is located within the castable material.

[0034] Reference Figure 1-4 This application describes a protective device for a coke oven 1.

[0035] According to this embodiment of the coke oven protection device, there are a first protection part and a second protection part. The first protection part is connected between the coke oven 1 and the second protection part, thereby realizing effective protection of the coke oven masonry.

[0036] The first protective section includes a barrier layer, a protective plate, and a connecting plate 2. The protective plate includes several plates 3, each with a groove 4. A balancing connecting component is installed in the groove 4. The plates 3 are connected by the connecting plate 2 and some of the balancing connecting components, which improves the deformation resistance of the protective plate and enhances its stability and reliability. The barrier layer is connected to the end of the protective plate away from the connecting plate 2 and fits tightly against the furnace body, ensuring that the raw coal gas does not escape from the furnace door during the coking process, while also providing good heat insulation for the furnace body.

[0037] At least a portion of the second protective part abuts against the connecting plate 2. The second protective part includes the furnace column 5 and the telescopic assembly. The telescopic assembly is arranged opposite to each other on both sides of the furnace column 5 and is at least partially located inside the furnace column 5 to adapt to the thermal expansion of the furnace body under high temperature environment, ensure the integrity of the masonry, and thus reduce the safety risks that may occur in the coke oven during production.

[0038] In this utility model, the material of the connecting plate 2 can be ordinary carbon steel. This application embodiment does not limit the material of the connecting plate 2, and it can be selected according to actual needs.

[0039] In one implementation, a casting material 6 is provided in the groove 4, and the balancing connection component is located in the casting material 6 to avoid stress concentration in the casting material 6, ensuring that the protective plate is evenly stressed, thereby helping to improve its service life.

[0040] In one implementation, the balancing connection assembly includes a protruding strip 7, a clamping plate 8, a transverse reinforcing bar 9, and a longitudinal reinforcing bar 10. The clamping plate 8 is clamped to the protruding strip 7, the transverse reinforcing bar 9 overlaps above the longitudinal reinforcing bar 10, and the longitudinal reinforcing bar 10 passes through the clamping plate 8 to connect several plates 3 in sequence. This not only forms a stable grid structure in the groove 4, but also further improves the connection strength between the plates 3, thereby enabling the protective plate to effectively resist various stresses and deformations during the operation of the coke oven.

[0041] In one implementation, the protruding strip 7 is set at the bottom of the groove 4, part of the clamping plate 8 is located above the protruding strip 7, and the longitudinal steel bars 10 are staggered above the protruding strip 7, which enhances the rigidity and strength of the plate 3, thereby improving its stability and load-bearing capacity, so as to provide better protection for the coke oven and ensure production safety.

[0042] In one embodiment, the telescopic assembly includes a fixed plate 11, a movable plate 12, a spring 13, and a column 14. The movable plate 12 is located above the fixed plate 11, the spring 13 is located between the movable plate 12 and the fixed plate 11, and the column 14 passes through the fixed plate 11, the spring 13, and the movable plate 12 in sequence and is fixedly connected to the movable plate 12. This arrangement provides space for the thermal expansion and contraction of the coke oven, ensuring the airtightness and heat insulation of the oven body. In the process of the column 14 driving the movable plate 12 to move up and down, the spring 13 can be compressed or rebound, thereby providing buffer protection for the coke oven.

[0043] In one implementation, the fixed plate 11 is fixedly connected to the furnace column 5, and the end of the column 14 near the movable plate 12 passes through the furnace column 5 and abuts against the connecting plate 2, so as to better withstand the stress deformation generated during the thermal expansion and contraction of the coke oven, thereby improving its safety and reliability.

[0044] In one implementation, the barrier layer includes a sealing plate 15 and a ceramic fiber blanket 16. The ceramic fiber blanket 16 is disposed above the sealing plate 15. Part of the sealing plate 15 is connected to the castable refractory 6 to ensure the stable and reliable sealing performance of the masonry, prevent leakage of raw coal gas, and provide excellent heat insulation performance to ensure the service life of the coke oven.

[0045] This utility model does not limit the type of sealing plate 15, and can be selected according to actual needs. For example, the sealing plate 15 can be made of 304 stainless steel plate, which can effectively prevent corrosion from coke oven gas and block smoke and fire from escaping from the coke oven masonry.

[0046] As one implementation method, a furnace door frame 17 is provided at the bottom of the coke oven 1, and a plate 3 is located between two adjacent furnace door frames 17. Ceramic fiber felt 18 and ceramic fiber rope 19 are provided between the plate 3 and the furnace door frame 17, which effectively blocks the gap between the plate 3 and the furnace door frame 17, ensuring sealing and heat insulation effects.

[0047] As one implementation method, a limiting block 20 is provided at the bottom of the plate 3 and a limiting groove is provided at the top of the furnace door frame 17. The limiting block 20 is engaged in the limiting groove, which facilitates the precise positioning of the plate 3 and prevents it from shifting during use, thereby improving the stability of the connection structure.

[0048] In one implementation, the connecting plate 2 and the plate 3 are connected by bolts, and the plate 3 and the furnace door frame 17 are connected by bolts. This can effectively prevent connection failure caused by thermal expansion and contraction, and greatly improve the reliability of the connection structure.

[0049] During installation, the aforementioned coke oven protection device involves first connecting several plates 3 sequentially using connecting plates 2 and longitudinal reinforcing bars 10. Then, refractory 6 is filled into the grooves 4. A sealing plate 15 and a ceramic fiber blanket 16 are then laid sequentially on top of the refractory 6 before the entire device is installed onto the oven. This installation method eliminates the need for grouting during the oven drying process, significantly reducing labor intensity, improving work efficiency, decreasing construction costs, shortening the coke oven construction cycle, and improving construction quality.
