Description

Technical Field

[0001] This utility model relates to the technical field of coke oven side doors, specifically a coke oven side door for a 7.63-meter coke oven machine. Background Technology

[0002] Currently, coke ovens are widely used in coking plants. Coke ovens all have a coke-machine side door. Because the oven door contains high-temperature flames and gases, it must be sealed to prevent the flames and gases from escaping. Existing sealing technology involves setting a ring-shaped blade along the edge of the oven door, allowing the blade to fit snugly against the oven body, thus achieving a seal.

[0003] During prolonged continuous operation of the furnace, the blade edge, a key component for sealing the furnace door, experiences a continuous rise in temperature, fluctuating within a relatively stable range. However, under prolonged exposure to high temperatures, some blade edges may deform, losing their original tight fit and becoming irregular. This significantly reduces the sealing effect between the blade edge and the furnace body. Reduced sealing leads to a series of problems, such as heat loss and gas leakage, greatly diminishing the practicality of the furnace door and affecting the normal operation of the furnace. Utility Model Content

[0004] The purpose of this utility model is to provide a 7.63-meter coke oven machine coke side door to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coke oven side door for a 7.63-meter coke oven, comprising a door body, a limiting mechanism body for connecting the door body and the oven body fixed on the surface of the door body, a plurality of sliding plates fixed on the surface of the door body, heat dissipation fins sliding in the inner cavity of the sliding plates, heat dissipation blocks fixed on the surface of the heat dissipation fins, a blade edge web plate fixed on the surface of the heat dissipation blocks, a guide strip fixed on the surface of the door body, an expansion block provided in the inner cavity of the guide strip for pushing the blade edge web plate by expansion, and the other end of the expansion block fixed to the surface of the blade edge web plate.

[0006] Preferably, a sealing plate for enhanced sealing is fixed to the surface of the blade edge web, and the sealing plate is disposed around the surface of the blade edge web.

[0007] Preferably, the heat sink is embedded inside the blade-edge web, and its contact surface is formed with a 0.1-0.3mm copper transition layer using a laser micro-cladding process. The space between the heat sink and the heat sink is filled with a liquid metal thermally conductive medium.

[0008] Preferably, the heat sink is made of copper, and the heat dissipation block is made of molybdenum-copper alloy.

[0009] Preferably, the expansion block is made of NiFe-Cr alloy foil, and the expansion block is disposed in the inner cavity of the guide strip.

[0010] Preferably, the expansion block has wedge surfaces on both sides, which are formed on the surface of the guide strip.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] In daily use, this invention can transfer heat from the blade edge inside the furnace to the outside through the heat dissipation fins and blocks, thereby achieving heat dissipation for the blade edge and improving its service life and practicality. In addition, as the blade edge continues to heat up, the expansion blocks expand, thereby compressing the blade edge and making it fit tightly against the furnace surface, further enhancing the practicality of the device.

[0019] 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.

[0020] Please see Figure 1-5As shown, a 7.63-meter coke oven coke oven side door includes a door body 1. A limiting mechanism body 2 for connecting the door body 1 to the oven body is fixed to the surface of the door body 1. Several sliding plates 3 are fixed to the surface of the door body 1. Heat sinks 6, made of copper, slide within the inner cavity of the sliding plates 3. Heat sink blocks 7, made of molybdenum-copper alloy, are fixed to the surface of the heat sinks 6. Copper has a melting point of 1083℃, and the molybdenum-copper alloy has a melting point of 2600℃. The heat sink blocks 7 can transfer heat to the heat sinks 6. The surface is fixed with a blade edge web plate 4. The heat sink 7 needs to be in direct contact with the blade edge web plate 4, so the temperature of the heat sink 7 will be higher than that of the heat sink 6. With the material settings, the service life of this device can be improved and the production cost can be reduced. The surface of the blade edge web plate 4 is fixed with a sealing plate 5 that strengthens the seal. The sealing plate 5 is set around the surface of the blade edge web plate 4. With the setting of the sealing plate 5, after the blade edge web plate 4 is attached to the furnace door frame, an L-shape is formed between the sealing plate 5 and the blade edge web plate 4, forming a secondary seal with the furnace door frame.

[0021] The heat sink 7 is embedded inside the blade-edge web 4, and its contact surface is formed with a 0.1-0.3mm copper transition layer using a laser micro-cladding process. Liquid metal thermally conductive medium is filled between the heat sink 6 and the heat sink 7 to reduce interfacial thermal resistance and ensure a heat flux density > 5 × 10⁻⁶ at 1000℃. 4 W / m 2 This improves the practicality of the device.

[0022] A guide strip 8 is fixed to the surface of the furnace door body 1. An expansion block 9 is provided in the inner cavity of the guide strip 8, which pushes the blade edge web 4 by expansion. The expansion block 9 is made of NiFe-Cr alloy foil and is located in the inner cavity of the guide strip 8. In this embodiment, the expansion coefficient of NiFe-Cr alloy foil is ≈14×10. -6 At ℃, after being heated, the expansion block 9 expands, which in turn pushes the blade web 4 and the sealing plate 5 toward the furnace body, further improving the sealing performance of the device.

[0023] The expansion block 9 has inclined wedge surfaces on both sides, which are formed on the surface of the guide strip 8. In this embodiment, the expansion block 9 is guided to expand in the direction of heating, thereby improving the practicality of the device.

[0024] The other end of the expansion block 9 is fixed to the surface of the blade web 4.

[0025] Working principle: After the furnace door body 1 is closed, the heat inside the furnace is transferred to the surface of the blade edge web plate 4. Then, under the action of the heat dissipation fins 6 and heat dissipation blocks 7, the heat is transferred outward to achieve the purpose of heat dissipation and avoid the problem of reduced sealing caused by high temperature deformation of the blade edge web plate 4. When the blade edge web plate 4 is continuously heated, the heat can be transferred to the expansion block 9, which can cause the expansion block 9 to expand. This causes the blade edge web plate 4 and the heat dissipation fins 6 to slide relative to the furnace door body 1 and the sliding plate 3, pushing the blade edge web plate 4 and the sealing plate 5 towards the furnace body, further improving the sealing performance of this device.
