Description
Technical Field
[0001] This utility model belongs to the field of coking technology, specifically relating to a folding coke oven inclined channel blockage cleaning device. Background Technology
[0002] In coking industry production, the coke oven is the core equipment, and its operational stability directly determines the quality of coke products and production efficiency. The coke oven chute, as a crucial channel connecting the combustion chamber and regenerator, bears the heavy responsibility of transporting gas and air and discharging post-combustion exhaust gases, making it a vital hub for ensuring the stability of the coke oven's thermal regime. However, with the continuous increase in the age of coke ovens, chute blockage has become increasingly prominent, becoming a major bottleneck restricting the efficient operation of coke ovens.
[0003] Blockage in the inclined channel leads to an imbalance in the distribution of gas and air, causing abnormal temperatures in some combustion chamber flues. This results in uneven coke maturation, leading to either under-coking or over-coking, severely impacting product quality. Simultaneously, obstructed airflow causes incomplete combustion, and combined with reduced heat exchange efficiency in the regenerator leading to increased exhaust gas temperature, this increases heat consumption and energy waste. Furthermore, localized high temperatures or pressure increases can cause overheating, cracking, and spalling of the furnace lining, and even gas leaks, posing safety hazards and damaging the furnace. In addition, poor heating due to blockage prolongs coking time, forcing companies to reduce coal loading or slow down production, resulting in decreased output. Increased difficulty in temperature control necessitates frequent manual intervention, significantly increasing maintenance frequency and labor intensity, thus affecting production continuity.
[0004] Currently, the industry commonly uses compressed air purging to clean obstructions in coke oven ducts, but this method has significant drawbacks. Because the duct is located at the bottom of the combustion chamber, long metal ducts are required, and multiple people must work together above the coal car to insert and remove the ducts. This not only requires a large workforce and high labor intensity but is also limited to maintenance periods, severely hindering the cleaning progress. More importantly, compressed air purging is very ineffective at removing highly adhesive or sintered blockages, failing to fundamentally solve the blockage problem. Therefore, a folding coke oven duct blockage cleaning device is urgently needed. Utility Model Content
[0005] To address some or all of the technical problems existing in the prior art, this utility model provides a foldable coke oven inclined passage blockage cleaning device. The blockage cleaning device is disposed above the inclined passage, which is connected to the combustion chamber. A viewing hole is provided at the top of the combustion chamber. The foldable coke oven inclined passage blockage cleaning device includes a first connecting rod, a second connecting rod disposed below the first connecting rod, a folding buckle hinged between the first connecting rod and the second connecting rod, a handle disposed at the end of the first connecting rod away from the second connecting rod, and a drill bit disposed at the end of the second connecting rod away from the first connecting rod. The drill bit is matched with the viewing hole and the inclined passage.
[0006] Furthermore, in the above-mentioned folding coke oven inclined duct blockage cleaning device, the handle is provided with an anti-slip and wear-resistant layer.
[0007] Furthermore, in the above-mentioned folding coke oven inclined channel blockage cleaning device, both the first connecting rod and the second connecting rod are telescopic rods, which can be extended and retracted by adjusting screws.
[0008] Furthermore, in the above-mentioned folded coke oven inclined passage blockage cleaning device, the drill bit has a V-shaped structure, and the drill bit and the second connecting rod are detachably connected.
[0009] The foldable coke oven inclined channel blockage cleaning device of this utility model has the following advantages and beneficial effects: This device has a simple structure and is easy to assemble and disassemble. The folding buckle can significantly reduce the height of the device when it is placed in the oven. It does not require the assistance of a coal car and can be operated by only two people. It breaks through the limitations of traditional duct cleaning, which requires multiple people to work together and is limited by maintenance period operations. It improves the flexibility of work arrangements. Moreover, the drill bit can more accurately and efficiently remove the sticky and sintered blockages compared to compressed air purging, avoiding the problem of incomplete cleaning. In addition, the telescopic connecting rod of this device can be adapted to different coke oven specifications, and the anti-slip and wear-resistant layer on the handle can effectively reduce the operation risk, making it highly practical.

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0013] like Figures 1 to 6 As shown, this utility model discloses a foldable coke oven inclined passage blockage cleaning device. The blockage cleaning device is disposed above the inclined passage 6, which is connected to the combustion chamber 7. The combustion chamber 7 has a viewing hole 8 at the top. The foldable coke oven inclined passage blockage cleaning device includes a first connecting rod 1, a second connecting rod 2 disposed below the first connecting rod 1, a folding buckle 3 hinged between the first connecting rod 1 and the second connecting rod 2, a handle 4 disposed at the end of the first connecting rod 1 away from the second connecting rod 2, and a chisel 5 disposed at the end of the second connecting rod 2 away from the first connecting rod 1. Specifically, the folding buckle 3 adopts a hinged structure, and its rotating shaft is made of high-strength wear-resistant pin shaft to ensure that the first connecting rod 1 and the second connecting rod 2 rotate smoothly during folding or unfolding, while being able to withstand the tension and pressure during cleaning operations to avoid breakage. The folding buckle 3 is also equipped with a locking mechanism (not shown in the figure). The locking mechanism can fix the angle of the connecting rod after the device is unfolded, so that the first connecting rod 1 and the second connecting rod 2 remain coaxial or at a preset tilt angle, ensuring that the cleaning force is effectively transmitted to the drill bit 5. The drill bit 5 is matched with the fire viewing hole 8 and the inclined channel 6.
[0014] As a specific embodiment, in the folding coke oven inclined channel blockage cleaning device of this utility model, the handle 4 is provided with an anti-slip and wear-resistant layer. The anti-slip and wear-resistant layer is made of high-temperature resistant rubber and is tightly attached to the surface of the handle 4 through a vulcanization process. Its surface is provided with anti-slip texture, which not only enhances the grip stability, but also isolates some heat transfer and protects the operator's hands.
[0015] In one specific embodiment, in the folding coke oven inclined passage blockage cleaning device of this utility model, both the first connecting rod 1 and the second connecting rod 2 are telescopic rods, which can be extended and retracted by adjusting screws. More specifically, the telescopic rod parts of the first connecting rod 1 and the second connecting rod 2 are composed of hollow metal tubes nested inside and outside. An adjustment hole is opened on the side wall of the outer tube. The adjusting screw passes through the adjustment hole and abuts against the inner tube. By loosening the adjusting screw, the inner tube can be pulled to change the overall length. After adjusting to the appropriate size, the screw can be tightened to fix it.
[0016] As a specific embodiment, in the folding coke oven inclined passage blockage cleaning device of this utility model, the drill bit 5 has a V-shaped structure, and the drill bit 5 and the second connecting rod 2 are detachably connected. More specifically, the drill bit 5 and the second connecting rod 2 are connected by threads. This setting makes it easy to replace the drill bit 5 of different specifications according to the type of blockage. The V-shaped included angle of the drill bit 5 has been optimized to ensure that it can achieve the dual function of breaking and scraping during the lifting and pressing operation. Especially for the coke powder sintered blocks and tar adhesions commonly found in the coke oven inclined passage 6, the cleaning effect is significantly better than that of traditional air ducts.
[0017] The working principle of this utility model's foldable coke oven inclined channel blockage cleaning device is as follows: First, based on the height of the combustion chamber 7 and the depth of the inclined chute 6 of the coke oven to be cleaned, adjust the extension lengths of the first connecting rod 1 and the second connecting rod 2 respectively by adjusting the screws to make the total length of the device adapt to the operation requirements; then, the operator folds the first connecting rod 1 and the second connecting rod 2 to a smaller angle using the folding buckle 3, with the drill bit 5 facing down, and slowly inserts the drill bit 5 and the second connecting rod 2 into the combustion chamber 7 through the viewing hole 8 at the top of the combustion chamber 7 until the second connecting rod 2 is fully inserted; next, insert the first connecting rod 1 through the viewing hole 8, and simultaneously adjust the angle of the folding buckle 3 to gradually unfold the first connecting rod 1 and the second connecting rod 2. At this time, the operator slowly lowers the device using the handle 4 until the drill bit 5 contacts the blockage at the inclined chute 6; During the cleaning operation, the operator holds the handle 4 with both hands and repeatedly pulls the handle 4 to move the drill bit 5 up and down. The V-shaped drill bit 5 is used to impact and break up the blockage. The sticky material on both sides is scraped away from the inner wall of the inclined channel 6. When encountering a deeper blockage, the operator presses down on the handle 4 and rotates it slightly to allow the drill bit 5 to penetrate deeper into the inclined channel 6 for a thorough cleaning of the blockage. If there is a blockage in different parts of the inclined channel 6, the angle of the drill bit 5 can be changed by adjusting the angle of the folding buckle 3 to ensure that there are no blind spots in the cleaning. After cleaning, first fold the first connecting rod 1 and the second connecting rod 2 using the folding buckle 3, and then take out the first connecting rod 1, the second connecting rod 2 and the drill bit 5 from the fire viewing hole 8 in sequence to complete a single cleaning operation.
[0018] In summary, compared with the prior art, the folding coke oven inclined channel blockage cleaning device of this utility model has the following advantages and beneficial effects: This device has a simple structure and is easy to assemble and disassemble. The folding buckle 3 can significantly reduce the height of the device when it is placed in the oven. It does not require the assistance of a coal car and can be operated by only two people. It breaks through the limitations of traditional duct cleaning, which requires multiple people to work together and is limited by maintenance period operations. It improves the flexibility of work arrangements. Moreover, the drill bit 5 can more accurately and efficiently remove the sticky and sintered blockages compared to compressed air purging, avoiding the problem of incomplete cleaning. Furthermore, the telescopic connecting rod of this device can be adapted to different coke oven specifications, and the anti-slip and wear-resistant layer on the handle 4 can effectively reduce the operation risk, making it highly practical.
