Description

Technical Field

[0001] This utility model relates to the field of blast furnace technology, specifically to a device for treating coke blockage at blast furnace tuyeres. Background Technology

[0002] Coke is a crucial solid fuel in blast furnace production, serving to support the furnace structure and provide a reducing atmosphere and heat. If fluctuations occur in the furnace conditions, coke inside can be carried by the hot blast airflow to the inside of the tuyeres, blocking the inspection holes and causing coke jamming. This prevents personnel at the water control station from observing the tuyeres through the inspection holes and from adjusting the angle of the pulverized coal injection lance, affecting normal tuyere inspections and pulverized coal injection, significantly impacting normal blast furnace production. Furthermore, pulverized coal injection is an important ironmaking technique for reducing the coke ratio, adjusting furnace conditions, and saving costs. Failure to adjust the pulverized coal lance angle in a timely manner can easily cause the injected pulverized coal to wear through the tuyeres sleeve, leading to production accidents. Therefore, timely handling of coke jamming at the tuyeres is essential.

[0003] The conventional method for dealing with coke blockage at the tuyeres is to drastically reduce blast furnace air volume using steel rods to hold the tuyeres in place. This method not only affects blast furnace output and increases production costs, but also poses a risk of burns to workers who are exposed to hot slag and blast from the furnace during the process, potentially leading to accidents.

Only one person is needed to supervise while the operator works, eliminating safety hazards. It does not require blast furnace blast reduction or disassembly of the tuyeres, eliminating the risk of hot air backflow causing burns to workers and generating no noise. It significantly improves work efficiency without affecting the blast furnace, minimizing and eliminating related safety accidents. What was previously a high-risk operation has become a risk-free routine operation. Furthermore, the device is equipped with a vent valve, allowing residual compressed air pressure to be released before dismantling the device after operation, preventing personnel injury from residual pressure and reducing safety hazards. It can be widely used to treat coke jamming at tuyeres during normal blast furnace production and has significant promotional value. Attached Figure Description

[0014] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0015] Please see Figure 1-5 As shown, a device for treating coke blockage at blast furnace tuyeres includes: a direct-blowing pipe 1, an elbow 2 fixedly installed on the direct-blowing pipe 1, a tuyer cover 3 fixedly installed on the elbow 2, and a tuyer insert plate installed on the tuyer cover 3. The direct-blowing pipe 1, elbow 2, tuyer cover 3, and tuyer insert plate are all prior art, and their installation positions and structures on the blast furnace are also prior art. The accompanying drawings in this application are for reference only, taking into account actual conditions. A connecting component 4 is disposed on the tuyer cover 3. An installation component 5 is installed on the connecting component 4, and a blowing component 6 is installed on the installation component 5. The installation component 5 includes: a connecting sleeve 51 disposed on one side of the connecting component 4, and a nut 52 welded to one side of the connecting sleeve 51. The connecting component 4 is first connected and fixed to the tuyer cover 3. The blowing component 6 is connected to the connecting component 4 through the installation component 5. The nut 52 is used to connect the inspection hole. The connecting sleeve 51 can be quickly connected to the blowing component 6.

[0016] When dealing with coke stuck in the blast furnace tuyeres, this device first connects and fixes the connecting component 4 to the tuyeres cover 3, then connects the mounting component 5 to the connecting component 4, and finally connects the blowing component 6 to the mounting component 5, so that the blowing component 6, the mounting component 5, the connecting component 4 and the direct blowing pipe 1 form a channel. Compressed air enters the tuyeres cover 3 from the blowing component 6 to clear the coke stuck in the tuyeres. The compressed air pressure blows the coke in the tuyeres into the direct blowing pipe 1, and the hot air flow carries the coke into the furnace, thereby solving the problem of coke stuck in the tuyeres.

[0017] Based on the above implementation scheme, the connecting component 4 includes: a fixed pipe 41, welded to the vent cover 3, and having a threaded groove on the outside; a connecting cap 43, threadedly installed on the fixed pipe 41; a connecting pipe 42, welded to the connecting cap 43; and an exhaust component 44, installed on the top of the connecting pipe 42 for exhaust and pressure relief. The exhaust component 44 includes: a three-way pipe 441, installed in the middle of the connecting pipe 42; and an exhaust valve 442, fixedly installed on the top of the three-way pipe 441. The connecting pipe 42 is threadedly fixedly installed on the fixed pipe 41 through the connecting cap 43, and the connecting pipe 42 is fixedly installed at both ends of the three-way pipe 441. The exhaust valve 442 is installed on the top of the three-way pipe 441 through a vertical pipe.

[0018] When cleaning the stuck coke, the connecting cap 43 is threaded onto the fixed pipe 41, thereby connecting and fixing the entire connecting pipe 42 and the tee pipe 441 to the air outlet cover 3. After the cleaning operation is completed, when dismantling the device, first open the exhaust valve 442 to release the residual pressure of compressed air, thereby avoiding personnel being injured by residual pressure and reducing safety hazards.

[0019] Based on the above implementation plan, and referring to Figure 3 and Figure 4 The mounting assembly 5 also includes: two rotating rods 53, which are rotatably mounted on both sides of the connecting sleeve 51; an arc head 54, which is welded to the end of the rotating rod 53; and a ring 55, which is fixedly mounted on the rotating rod 53. Both sides of the connecting sleeve 51 are provided with through slots, and the arc head 54 rotates in the through slots. The connecting sleeve 51 is threadedly mounted on the left side of the connecting pipe 42 by a nut 52.

[0020] During installation, the nut 52 on the left side of the connecting sleeve 51 is threaded onto the right side of the connecting pipe 42 (the right side of the connecting pipe 42 has a threaded groove), thereby connecting the connecting sleeve 51 and the connecting pipe 42. The rotating rod 53 rotates on the outside of the connecting sleeve 51, which can adjust the position of the arc head 54 in the connecting sleeve 51. The ring 55 makes it easy to pull and open the rotating rod 53.

[0021] Based on the above implementation plan, and referring to Figure 3 The blower assembly 6 includes: a connector 61, which is inserted into the connecting sleeve 51; and a rubber tube 62, which is fixedly installed on the connector 61. The connector 61 is adapted to the connecting sleeve 51 and can be snapped into the connecting sleeve 51. Compressed air is connected to the rubber tube 62.

[0022] When blowing compressed air into the direct blow pipe 1, adjust the rotating rod 53 on the connecting sleeve 51 to... Figure 4In the indicated state, the arc head 54 is moved away from the center of the connecting sleeve 51. Then, the connector 61 on the rubber tube 62 is inserted into the connecting sleeve 51. Then, the rotating rod 53 is flipped so that the arc head 54 is close to the center of the connecting sleeve 51, and the connector 61 is squeezed and limited in the connecting sleeve 51, thereby connecting the rubber tube 62 and the connecting sleeve 51. Compressed air is injected into the rubber tube 62, and the compressed air is delivered to the connecting pipe 42 through the rubber tube 62, and then delivered to the direct blowing pipe 1 through the connecting pipe 42. The pressure of the compressed air is used to blow the coke in the tuyeres into the direct blowing pipe 1, and the coke is carried into the furnace by the hot air flow, thereby solving the problem of coke stuck in the tuyeres.
