Description

Technical Field

[0001] This utility model relates to the technical field of coke oven door equipment, and in particular to an easy-to-maintain coke oven door sealing structure. Background Technology

[0002] As a key component of coke ovens, the sealing performance of coke oven doors directly affects the production efficiency and environmental performance of coke ovens. Existing coke oven door sealing structures mostly adopt an integral sealing frame fixedly connected to the door body. Under long-term high temperature, dust, and mechanical vibration conditions, the sealing components are prone to wear, aging, or deformation, leading to sealing failure.

[0003] However, the existing structure has the following drawbacks: it lacks an adaptive adjustment mechanism for the sealing gap. When the furnace door is deformed by heat or the seal is worn, it cannot compensate for the gap in real time, which can easily lead to gas leakage. Therefore, an easy-to-maintain coke oven door sealing structure is provided. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an easy-to-maintain coke oven door sealing structure. A disc spring provides a rebound force to assist the sealing block in pressing against the convex edge to achieve a seal. When the sealing block wears, turning the adjusting screw can push the adjusting plate to move, increasing the compression of the disc spring. The rebound force automatically compensates for the gap, ensuring the sealing effect and preventing gas leakage. Furthermore, the heat dissipation fins and the first heat dissipation hole can assist the sealing block in dissipating heat, overcoming the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An easy-to-maintain coke oven door sealing structure includes a connecting frame. One side of the connecting frame is connected to a door frame via a rotating assembly. A locking assembly is provided between one end of the door frame and the connecting frame for cooperation. A guide frame is provided in the middle of the door frame. A sealing block is movably engaged in the guide frame. Disc springs are fixed at the four corners of the outer side of the sealing block. An adjustment assembly is connected to the end of the four disc springs away from the sealing block. A support frame is connected to the outer side of the guide frame. The adjustment assembly is connected to the support frame. A raised edge is provided on the outer side of the connecting frame. Heat dissipation fins are provided at equal intervals in the middle of the outer side of the sealing block.

[0007] As a further embodiment of this utility model: the adjustment assembly includes an adjustment plate connected to the end of the four disc springs away from the sealing block, and an adjustment screw is rotatably connected to the middle of the adjustment plate via a bearing, with a U-shaped fixing seat screwed onto the adjustment screw.

[0008] As a further embodiment of this utility model: the support frame includes four connecting columns fixed at the four corners on the outward side of the guide frame, a rectangular frame is sleeved on the four connecting columns, a support tube is sleeved on the part of the four connecting columns located between the guide frame and the rectangular frame, and a first nut is screwed to the end of each of the four connecting columns.

[0009] As a further improvement of this utility model, the two ends of the U-shaped fixing seat are fixedly connected to the two ends of the rectangular frame.

[0010] As a further improvement of this utility model, the adjustment plate is provided with a first heat dissipation hole on its side.

[0011] As a further embodiment of this utility model: the rotating assembly includes two first connecting blocks symmetrically arranged at one end of the door frame, and two second connecting blocks symmetrically fixed on one side of the connecting frame. Connecting pins are fixed on the two second connecting blocks, and the two first connecting blocks are rotatably connected to the upper and lower ends of the connecting pins respectively.

[0012] As a further embodiment of this utility model: the locking component includes a locking block fixed to the other end of the door frame, a U-shaped seat fixed to the other side of the connecting frame, a locking rod rotatably connected to the U-shaped seat via a pin, a second nut screwed onto the locking rod, a latch provided on the locking block, and the locking rod and the latch forming a latching engagement.

[0013] As a further improvement of this utility model: the U-shaped fixing base has screw holes at equal intervals on both sides, and each screw hole is screwed with an L-shaped elastic protective plate by bolts.

[0014] As a further improvement of this utility model, each of the L-shaped elastic protective plates is provided with second heat dissipation holes at equal intervals.

[0015] As a further improvement of this utility model: a sealing ring is provided on the other side of the connecting frame, and mounting holes are provided at all four corners of the connecting frame.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. The disc spring provides a rebound force to help the sealing block and the convex edge to press together to achieve a seal. When the sealing block wears, turning the adjusting screw can push the adjusting plate to move, increase the compression of the disc spring, and automatically compensate for the gap with the rebound force to ensure the sealing effect and prevent gas leakage. In addition, the heat dissipation fins and the first heat dissipation hole can help the sealing block dissipate heat.

[0018] 2. The L-shaped elastic protective plate can buffer the impact force and reduce the damage to the furnace door. Its second heat dissipation hole also assists in heat dissipation. The four corner mounting holes of the connecting frame are convenient for fixing, and the sealing ring can also ensure the sealing of the connection between the connecting frame and the furnace body.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1, referring to Figure 1-6A maintenance-friendly coke oven door sealing structure includes a connecting frame 1. One side of the connecting frame 1 is connected to a door frame 7 via a rotating assembly. A locking assembly is provided between one end of the door frame 7 and the connecting frame 1 for cooperative use. A guide frame 14 is provided in the middle of the door frame 7. A sealing block 15 is movably engaged in the guide frame 14. Disc springs 19 are fixed at the four corners of the outer side of the sealing block 15. An adjustment assembly is connected to the end of the four disc springs 19 away from the sealing block 15. A support frame is connected to the outer side of the guide frame 14. The adjustment assembly is connected to the support frame. A raised edge 12 is provided on the outer side of the connecting frame 1. Heat dissipation fins 27 are provided at equal intervals in the middle of the outer side of the sealing block 15.

[0028] The adjustment assembly includes an adjustment plate 16 connected to one end of four disc springs 19 away from the sealing block 15. An adjustment screw 5 is rotatably connected to the middle of the adjustment plate 16 via a bearing. A U-shaped fixing seat 6 is screwed onto the adjustment screw 5. A first heat dissipation hole 17 is provided on the side of the adjustment plate 16.

[0029] The support frame includes four connecting posts 28 fixed at the four corners of the guide frame 14 on the outward side. A rectangular frame 18 is sleeved on the four connecting posts 28. A support tube 21 is sleeved on the part of the four connecting posts 28 between the guide frame 14 and the rectangular frame 18. A first nut 20 is screwed to the end of each of the four connecting posts 28. The two ends of the U-shaped fixing seat 6 are fixedly connected to the two ends of the rectangular frame 18.

[0030] The rotating assembly includes two first connecting blocks 13 symmetrically arranged at one end of the door frame 7, and two second connecting blocks 3 symmetrically fixed on one side of the connecting frame 1. Connecting pins 2 are fixed on the two second connecting blocks 3, and the two first connecting blocks 13 are rotatably connected to the upper and lower ends of the connecting pins 2 respectively.

[0031] The locking assembly includes a locking block 8 fixed to the other end of the door frame 7, a U-shaped seat 11 fixed to the other side of the connecting frame 1, a locking rod 10 rotatably connected to the U-shaped seat 11 via a pin, a second nut 9 screwed onto the locking rod 10, a bayonet 26 provided on the locking block 8, and the locking rod 10 and the bayonet 26 forming a locking engagement.

[0032] A sealing ring 24 is provided on the other side of the connecting frame 1, and mounting holes 23 are provided at the four corners of the connecting frame 1. The connecting frame 1 can be installed at the door opening of the coke oven by using bolts through the mounting holes 23. The sealing ring 24 can ensure the sealing effect of the connection between the connecting frame 1 and the oven body.

[0033] After the door frame 7 is closed, rotate the locking lever 10 to engage with the latch 26, tighten the second nut 9 so that the second nut 9 abuts against the latch block 8, and the auxiliary door frame 7 is tightly closed. This causes the sealing block 15 and the guide frame 14 to abut against the protruding edge 12. At the same time, the disc spring 19 is compressed, and the rebound force provided by the disc spring 19 helps the sealing block 15 to abut against the protruding edge 12, thus achieving a seal. Even if the sealing block 15 is worn, the adjusting plate 16 can be moved towards the furnace body by turning the adjusting screw 5, increasing the compression of the disc spring 19. The rebound force provided by the disc spring 19 achieves automatic compensation, ensuring the sealing effect. The heat dissipation fins 27 and the first heat dissipation hole 17 can assist the heat dissipation of the sealing block 15.

[0034] Example 2 is an optimization based on Example 1, specifically:

[0035] The U-shaped mounting base 6 has screw holes 25 evenly spaced on both sides. Each screw hole 25 is bolted with an L-shaped elastic protective plate 4. Each L-shaped elastic protective plate 4 has a second heat dissipation hole 22 evenly spaced on it.

[0036] When a foreign object impacts the furnace door, the evenly arranged L-shaped elastic protective plates 4 can provide a large degree of protection against the impact. The L-shaped elastic protective plates 4 bear the impact force and buffer the impact force, effectively reducing the damage to the furnace door and minimizing losses. In addition, the L-shaped elastic protective plates 4 are provided with second heat dissipation holes 22 to help dissipate heat.

[0037] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
