Description

Technical Field

[0001] This application generally relates to the field of coke oven equipment technology. More specifically, this application relates to a coke oven door; further, this application also relates to a coke oven. Background Technology

[0002] In the coking process, the coke oven door plays a crucial role as a key piece of equipment. However, existing coke oven doors suffer from numerous problems. On the one hand, due to prolonged exposure to high temperatures and the effects of mechanical wear, thermal stress deformation, and insufficient spring compression, the sealing performance of the door's blade edges gradually deteriorates. On the other hand, inadequate door sealing allows raw coal gas generated during coking to easily escape when the pressure in the coke oven's gas collecting pipe increases, causing serious pollution to the surrounding environment.

[0003] To address the issue of smoke emanating from the furnace door, operators currently use refractory clay and rock wool to seal the smoke vents along the door's edges. However, this method requires repeated application after each coal charging operation, resulting in frequent work and failing to fundamentally resolve the problem. Furthermore, furnace doors with deformed edges must be transported to the furnace door repair station for correction or replacement by maintenance personnel, making the entire repair process complex and extremely labor-intensive. Additionally, the process of sealing the smoke vents requires operators to work in high-temperature environments, which negatively impacts their health.

[0004] In view of this, there is an urgent need to provide a coking oven door and coking oven that can effectively reduce the emission of tar and soot from the oven door. Utility Model Content

[0005] In order to at least solve one or more of the technical problems mentioned above, this application proposes, in several aspects, a coking oven door and a coking oven that effectively reduce the emission of tar and soot from the oven door.

[0006] In a first aspect, this application provides a coking oven door, comprising: a door body having a door blade edge on its edge; a support member fixedly disposed on the outside of the door blade edge, and a filling gap being formed between the support member and the door blade edge; and a sealing filler filling the filling gap.

[0007] In some embodiments, the support member is an angle steel with a width of 25-35 mm and a thickness of 3-5 mm.

[0008] In some embodiments, the angle steel is fixed to the outer side of the furnace door blade edge by spot welding.

[0009] In some embodiments, the angle steel is arranged continuously along the circumferential direction of the furnace door blade edge.

[0010] In some embodiments, the sealing filler is a ceramic fiber circular braided rope, and the diameter of the ceramic fiber circular braided rope is 30 mm.

[0011] In some embodiments, the ceramic fiber circular braided rope is installed by pre-compression filling, so that it remains in an expanded and sealed state under high-temperature conditions.

[0012] In a second aspect, this application provides a coking oven, the door of which includes the aforementioned coking oven door.

[0013] The coking oven door and coking oven provided above, in this embodiment of the application, by adding a support member to the outside of the door knife edge to prevent deformation of the door knife edge, and filling the gap between the support member and the door knife edge with a sealing filler to block tar and soot, a two-layer sealing structure with both support and sealing functions is formed, which enhances the overall sealing effect of the door, effectively reduces the amount of raw coal gas escaping, and protects the surrounding environment.

[0022] The specific embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0023] like Figure 1 As shown, in some embodiments, this application provides a coking oven door 100, including: a door body 101 with a door blade edge 102 at its edge; a support member 103 fixedly disposed on the outside of the door blade edge 102, and a filling gap is formed between the support member 103 and the door blade edge 102; and a sealing filler that fills the filling gap.

[0024] The coking oven door provided in this application includes a door body 101, on which a protruding door brick is provided. A door blade edge 102 is provided on the side of the door brick, meaning the edge of the door body 101 has a door blade edge 102. In traditional oven door structures, the door blade edge 102 serves to cooperate with the oven door frame to achieve a seal. To prevent the door blade edge 102 from failing to seal properly under long-term high temperatures and mechanical wear, leading to the escape of raw coal gas, this application adds a support member 103 to the outside of the door blade edge 102. A filling gap is formed between the support member 103 and the door blade edge 102, and a sealing filler is filled in the filling gap. Those skilled in the art will understand that the function of the support member 103 is to provide additional support for the door blade edge 102, preventing it from deforming under high-temperature conditions, thereby ensuring the sealing performance between the door blade edge 102 and the oven door frame. Simultaneously, the sealing filler effectively seals tar and soot, preventing them from escaping into the surrounding environment.

[0025] The solution proposed in this application adds a support member 103 to the outside of the furnace door knife edge 102 to prevent deformation of the furnace door knife edge 102. A sealing filler to block tar and soot is filled in the gap between the support member 103 and the furnace door knife edge 102, thus forming a two-layer sealing structure that combines support and sealing functions. This enhances the overall sealing effect of the furnace door, effectively reduces the amount of raw coal gas escaping, and protects the surrounding environment. Furthermore, in terms of maintenance optimization, in the prior art, after the furnace door knife edge 102 deforms, it needs to be transferred to a furnace door repair station for complex and labor-intensive maintenance. However, this application, through the combination design of adding an angle steel support member 103 and filling it with ceramic fiber circular braided rope, can slow down the deformation rate of the furnace door knife edge 102 to a certain extent, thereby reducing the frequency and workload of furnace door repairs and simplifying the maintenance process.

[0026] In one specific implementation, the support member 103 is an angle steel with a width of 25-35 mm and a thickness of 3-5 mm.

[0027] The support member 103 in this application is made of angle steel, with a width designed to be any value between 25-35 mm and a thickness of any value between 3-5 mm. This size range is selected based on a comprehensive consideration of the actual stress conditions of the furnace door and the material properties, aiming to provide sufficient support for the furnace door's blade edge to prevent deformation under complex conditions such as high temperature and mechanical wear, ensuring a tight fit between the furnace door blade edge and the furnace door frame, maintaining good sealing performance, and effectively reducing the escape of tar and soot. At the same time, controlling the width and thickness of the angle steel within this range allows for minimizing material usage, reducing production costs, simplifying the installation process, and improving production efficiency while meeting support and sealing requirements, without negatively impacting the overall performance of the furnace door. This design optimizes cost and process while ensuring the furnace door's sealing performance and structural strength, demonstrating the practicality and economy of this application.

[0028] In one specific implementation, the support member 103 is made of angle steel with a width of 30 mm and a thickness of 4 mm. This specification of angle steel not only has sufficient supporting strength and resistance to deformation, but also can fit the installation space on the outside of the furnace door blade edge 102, avoiding interference with the normal operation of the furnace door due to excessive size.

[0029] In one specific implementation, the angle steel is fixed to the outside of the furnace door blade edge 102 by spot welding.

[0030] In this application, the angle steel is fixed to the outside of the furnace door blade edge 102 by spot welding. The angle steel fixed in this way can form a stable support structure on the outside of the furnace door blade edge 102, preventing the furnace door blade edge 102 from deforming under the influence of long-term high temperature, mechanical wear and other factors, thereby ensuring the sealing performance between the furnace door blade edge 102 and the furnace door frame and reducing the escape of tar and soot.

[0031] In one specific implementation, the angle steel is arranged continuously along the circumference of the furnace door knife edge 102.

[0032] In this application, angle steel is continuously arranged circumferentially along the furnace door blade edge 102 to form a complete support structure. This arrangement allows the furnace door blade edge 102 to be evenly stressed in all directions, preventing it from deforming under high temperature and wear. In addition, the circumferentially arranged angle steel can effectively disperse stress, extend the service life of the furnace door, reduce maintenance needs, simplify processes, and reduce the labor intensity and health risks of operators.

[0033] In one specific implementation, angle steel is only installed at the four corners of the coke oven door. Those skilled in the art will understand that corners are stress concentration areas, prone to deformation due to mechanical and thermal stress. Installing angle steel at these locations provides targeted reinforcement, preventing edge deformation and improving sealing performance. Simultaneously, this design reduces the amount of angle steel used, lowering material and manufacturing costs; it simplifies the installation process, reduces welding workload, and improves production efficiency. By rationally designing the size and shape of the angle steel, the sealing and strength requirements of the oven door are met without affecting overall performance. This design optimizes cost and process while ensuring sealing and strength.

[0034] In some embodiments, the sealing filler is a ceramic fiber circular braided rope, and the diameter of the ceramic fiber circular braided rope is 30 mm.

[0035] In this application, the sealing filler is a 30 mm diameter ceramic fiber circular braided rope. Ceramic fiber circular braided rope possesses excellent high-temperature resistance and good elasticity, enabling it to remain stable over long periods in high-temperature environments. Filling the gap between the furnace door blade edge 102 and the angle steel with it effectively fills the gap, forming a sealing barrier. This design significantly reduces the escape of tar and soot, improving the sealing performance of the furnace door. Simultaneously, the use of ceramic fiber circular braided rope reduces maintenance frequency and workload, simplifies maintenance procedures, and reduces the labor intensity and health risks for operators.

[0036] In one specific implementation, the ceramic fiber circular braided rope is installed by pre-compression filling, which keeps it in an expanded and sealed state under high-temperature conditions.

[0037] In this application, the ceramic fiber circular braided rope is installed in the filling gap between the furnace door knife edge 102 and the angle steel using a pre-compression filling method. The principle of the pre-compression filling method is that the ceramic fiber circular braided rope is pre-compressed during installation and then placed into the filling gap. The ceramic fiber circular braided rope expands under high temperature, further filling the tiny gaps caused by thermal expansion and contraction, thereby maintaining stable sealing performance and preventing the escape of tar and soot. In other words, the ceramic fiber circular braided rope in this solution, installed using a pre-compression filling method, is adaptive, able to adapt to minor deformations of the furnace door, improving the reliability and stability of the device, reducing maintenance frequency and workload, simplifying maintenance procedures, and reducing the labor intensity and health risks for operators.

[0038] In some embodiments, this application also provides a coking oven, wherein the oven door 100 of the coking oven includes the oven door 100 of the coking oven described above.

[0039] This application also provides a coking oven whose door adopts the aforementioned coking oven door design. This design effectively improves the sealing performance of the door and reduces the escape of tar and soot by adding angle steel to the outside of the door blade edge 102 and filling it with ceramic fiber circular braided rope. This improved coking oven door not only enhances the environmental performance of the production process but also reduces the labor intensity and health risks for operators, while simplifying maintenance procedures and reducing maintenance costs.

Many modifications, alterations, and alternatives will arise for those skilled in the art without departing from the spirit and intent of this application.
