Description

Technical Field

[0001] This utility model belongs to the field of dry quenching technology in coking plants, specifically relating to a coke leveling device on the top of the coke tank in a dry quenching vehicle. Background Technology

[0002] In recent years, coking plant production processes have been continuously upgraded, and dry quenching has become the mainstream method for quenching red-hot coke in coke ovens. In dry quenching systems with a processing capacity greater than 120 tons / hour, circular rotary coke cans are widely used for receiving and transporting red-hot coke due to their adaptability. With the optimization and improvement of single-furnace output, the total amount of coke in the circular rotary coke cans has gradually increased. The coke itself is large in size and easily accumulates during unloading, resulting in uneven distribution of coke within the can. The highest point of coke accumulation often exceeds the can's rim, posing new challenges to the stable operation of the dry quenching system. In current mainstream dry quenching elevator systems, the can lid needs to be closed on top of the can in the elevator area. However, the increased height of the red-hot coke alters the relative position between the can lid and the red-hot coke inside, creating potential hazards for subsequent equipment operation.

[0003] As the red-hot coke rises, it easily bumps against the insulation material at the bottom of the coke can lid. Repeated and frequent bumping can cause the insulation material to loosen and fall off, creating a vicious cycle of "bumping - falling off - reduced pressure - accelerated falling off." Once the insulation material is damaged, the red-hot coke (temperatures exceeding 1000℃) directly burns the steel structure of the coke can lid, causing it to burn through in a short time. This affects the safe and stable operation of the entire dry quenching elevator system, requiring the dry quenching system to be shut down for maintenance. Online repair of the insulation material takes 12-16 hours and is limited by high temperatures and site conditions, resulting in poor repair quality and often re-damage within 3 months. Replacing the entire coke can lid takes over 36 hours, severely impacting system efficiency. When red-hot coke adheres to the bottom of the coke can lid, at least three workers must work together, using a 6-meter pole to clean it from the edge of the coke platform. Each cleaning takes over 10 minutes, and 2-3 cleanings are required per shift. The work site is 4 meters above the ground, with a 380-volt quenching car electric arc circuit below. When personnel lean out to work, they face not only the risks of height but also the risk of being burned by the high-temperature coke canister and red-hot coke, posing a great safety hazard. Therefore, there is an urgent need for a coke leveling device on the top of the coke canister for dry quenching. Utility Model Content

[0011] 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.

[0012] like Figure 1 , Figure 2 , Figure 3As shown, this utility model discloses a coke leveling device for the top of a coke oven in a dry quenching system. The coke oven top leveling device is installed inside the hoist frame 8. The installation foundation of this device is the hoist frame 8 of the dry quenching system. This frame is an existing load-bearing structure. A crossbeam 9 is set in the middle of the hoist frame 8, and a guardrail 10 is set above the crossbeam 9. A suspension beam 4 is set between the guardrail 10 and the crossbeam 9. The suspension beam 4 extends to the top of the crossbeam 9. The spacing between the two sets of suspension beams 4 matches the width of the coke oven 12, ensuring that the scraper plate 1 can fully cover the top area of ​​the coke oven 12. The surface is now perfectly level with no blind spots. The crossbeam 9 is connected to a fixed guide rail 11 on one side of the hoist frame 8. The coke canister with red coke and a coke canister cover can be raised and lowered along the fixed guide rail 11. The coke canister 12 is located below the hoist frame 8 and above the dry quenching car 13. The bottom of the dry quenching car 13 is rotatably connected to the traveling rail 14. The bottom of the dry quenching car 13 and the traveling rail 14 roll together, allowing it to move smoothly along the rail. A column 15 is installed on the top of the coke canister 12. The coke leveling device on the top of the coke canister of the dry quenching car includes a square hole opened in the middle of the suspension beam 4 and a vertically inserted... The support plate 2 inside the square hole, the coke scraper 1 set on one side of the support plate 2, and the bottom of the coke scraper 1 having a through groove matching the column 15. More specifically, to prevent the coke scraper 1 from vertically deforming during frequent coke scraping operations, two support plates 2 are set at intervals along the length of the inner side of the coke scraper 1. The support plates 2 and the coke scraper 1 are fully welded to ensure uniform force transmission and avoid damage caused by local stress concentration. The support plates 2 are made of high-strength steel plates, and their length is optimized so that the end can fit tightly with the crossbeam 9 after being inserted into the square hole. The coke scraper 1 serves as the direct... The components that come into contact with the high-temperature red coke are made of heat-resistant and wear-resistant steel, which can withstand the high temperature and friction impact of the red coke. Multiple anchor chains 6 are connected to the top of the trough by a fixing ring 7. The multiple anchor chains 6 are evenly distributed along the length of the trough. The anchor chains 6 are made of thick steel wire rope and have a certain weight. When the coke tank 12 passes under the hoist frame 8, the anchor chains 6 naturally droop under the action of gravity, contact the red coke protruding in the middle of the coke tank 12 and smooth it out, effectively filling the flat blank in the trough area and ensuring that the overall height of the red coke on the top of the coke tank 12 is uniform.

[0013] In one specific embodiment, in the coke leveling device on the top of the coke can of the dry quenching machine of this utility model, a safety hole is provided on the suspension beam 4 on one side of the square hole, and a fastener 5 is fixed in the safety hole. The edge of the fastener 5 is engaged in the slot (not shown in the figure) opened on the side wall of the support plate 2 to form a mechanical limit and prevent the support plate 2 from moving up and down or left and right when the coke is scraped, so as to achieve double fixation of the support plate 2.

[0014] In one specific embodiment, in the coke leveling device on the top of the coke tank of the dry quenching machine of this utility model, a protective rope 3 is connected between the coke scraper 1 and the guardrail 10. One end of the protective rope 3 is fixed in a pre-set round hole on the coke scraper 1 by a shackle, and the other end is connected to the pre-embedded lifting ring at the top of the guardrail 10. The protective rope 3 maintains an appropriate pre-tension, which does not affect the slight adaptive adjustment of the coke scraper 1 during operation, and can provide reliable secondary protection in case the device falls off accidentally, so as to prevent the device from falling into the coke tank 12 or the dry quenching machine 13 and causing a production accident.

[0015] In one specific embodiment, in the coke leveling device at the top of the coke tank of the dry quenching machine of this utility model, the number of anchor chains 6 is 5 to 8, more specifically, the number of anchor chains 6 is 5. Of course, the specific number of anchor chains 6 needs to be set according to the width of the groove in actual use.

[0016] The working principle of the coke leveling device on the top of the coke can of the dry quenching car of this utility model is as follows: First, by adjusting the fixed height of the suspension beam 4, a reasonable distance is maintained between the lower edge of the scraper plate 1 and the top of the coke can 12. This distance ensures that the coke can 12 passes smoothly and effectively scrapes off excess red-hot coke. When the dry quenching car 13 carries the coke can 12 filled with red-hot coke along the traveling track 14 into the hoist area, the red-hot coke inside the coke can 12 that is higher than the lower edge of the scraper plate 1 is forcibly scraped towards the edge of the coke can 12 by the scraper plate 1. The red-hot coke passing through the trough area is smoothed out by the anchor chain 6. After the coke can 12 carrying coke passes through the site and is aligned, it is suspended by hooks on both sides and passes through... The upper hoist lifts the coke can 12, along with its top cover, along the guide rails 11 on both sides to the top of the dry quenching furnace for subsequent operations. Before the coke can 12 reaches the bottom of the hoist, the coke can cover is suspended below the hoist frame. After the coke can 12 is aligned, the hoist controls the coke can cover to fall first and suspend it from the coke can 12 via hooks on both sides before starting the lifting operation. The entire leveling process is completed automatically as the dry quenching car 13 moves, without manual operation. After this device is put into use, there is no need for manual cleaning when there is red coke stuck inside the coke can 12 within a certain range.

[0017] In summary, compared with the prior art, the coke leveling device on the top of the coke can of this utility model for dry quenching has the following advantages and beneficial effects: This device has a simple structure and is easy to assemble and disassemble. Through the coordinated action of the scraper plate 1 and the anchor chain 6, it can automatically level the excessively hot coke inside the coke pot 12, preventing the hot coke from hitting the heat insulation material of the coke pot 12 cover from the source, reducing the probability of damage to the coke pot 12 cover, reducing maintenance frequency and cost, eliminating the need for manual intervention in the cleaning of low-volume sticky hot coke, completely eliminating the safety hazards of high altitude and high temperature during manual cleaning, and ensuring the stable operation of the device itself through multiple safety structure designs, avoiding the impact of device failure on the normal production of the dry quenching system, and effectively improving the overall production efficiency.
