Description

Technical Field

[0001] This utility model belongs to the field of coke quenching cans, specifically, it relates to a sealed coke can for dry quenching. Background Technology

[0002] Dry quenching is an important energy-saving and emission-reduction technology in the metallurgical industry. Its principle is to use inert gas to exchange heat with red coke in the dry quenching furnace to cool the red coke. The coke can is the equipment for transporting red coke. When pushing coke, the coke pusher pushes the red coke in the carbonization chamber through the coke guide grid into the coke can, and then the transport vehicle sends it to the bottom of the dry quenching hoist. Finally, the hoist lifts it to the top of the dry quenching furnace for coke loading.

[0003] However, existing coke canisters have an open top design. When transporting red coke, the red coke comes into contact with the air, causing it to burn directly in the air. The carbon dioxide and harmful gases produced by the combustion are directly released into the air. Furthermore, since the coke canister is not sealed, heat loss will occur, resulting in the inability to retain heat. In view of this, this utility model is proposed. Utility Model Content

Detailed Implementation

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] Please see Figures 1 to 6This utility model provides a technical solution: a sealed coke can for dry quenching, including a coke can 1, a first sealing cover 5, a second sealing cover 6, a water seal support 2 and a liquid injection nozzle 3. The top of the coke can 1 is provided with a feed port, and a water seal support 2 is fixedly sleeved on the outside of the feed port. A liquid injection nozzle 3 is installed on the upper side of one side of the water seal support 2, and a liquid discharge nozzle 4 is installed on the lower side of the other side of the water seal support 2.

[0031] The feed port of the coke tank 1 is covered with a first sealing cover 5 and a second sealing cover 6. A drive rack 7 for driving the sealing cover to move horizontally is fixed on the outside of the first sealing cover 5 and the second sealing cover 6. A cavity for installing the plug-in cover 8 is opened on one side of the first sealing cover 5. A return spring 9 abuts between the cavity and the plug-in cover 8. An embedding groove for the plug-in cover 8 is opened on the opposite side of the second sealing cover 6 and the first sealing cover 5.

[0032] The bottom of the coke tank 1 is equipped with a slag discharge end 10. A pull-out baffle 11 is installed on one side of the slag discharge end 10. The pull-out baffle 11 is fixed by a limiting block 12, which is sleeved on the outside of the shaft 13. The shaft 13 is fixed to the outer wall of the slag discharge end 10. Considering that the existing coke tank 1 has an open top design, when transferring red coke, the red coke comes into contact with air, causing it to burn directly in the air. The carbon dioxide and harmful gases produced by the combustion are directly emitted into the air. Furthermore, since the coke tank 1 is not sealed, heat loss will occur, leading to… In cases where heat cannot be retained, this device covers the inlet port of the casting with a first sealing cover 5 and a second sealing cover 6. At this time, the plug-in cover 8 will be inserted into the embedded groove, thereby filling the gap between the first sealing cover 5 and the second sealing cover 6. In order to further ensure the sealing effect, the injection nozzle 3 will cooperate with the booster pump 16 to pump the liquid in the liquid tank 14 into the interior of the water seal support 2, thereby further sealing the bottom of the first sealing cover 5, the second sealing cover 6 and the plug-in cover 8 through the liquid, thus ensuring the sealing of the coking tank 1.

[0033] The coke tank 1 has a liquid tank 14 fixed at the front end of its body. Inside the liquid tank 14, there is an L-shaped partition 15 for installing a booster pump 16. The negative pressure end of the booster pump 16 passes through the L-shaped partition 15 through a pipe and is located inside the liquid tank 14. The liquid delivery end of the booster pump 16 is connected to a liquid delivery pipe 17. The top of the liquid delivery pipe 17 is connected to the injection nozzle 3 through a telescopic conduit 18. By setting up the booster pump 16, the liquid in the liquid tank 14 is delivered to the injection nozzle 3.

[0034] The liquid tank 14 is equipped with an embedded liquid level sensor 19 at its upper end. The detection end of the embedded liquid level sensor 19 is located inside the liquid tank 14, and a sealing cap 20 is threadedly connected to one side of the upper end of the liquid tank 14. By setting the embedded liquid level sensor 19, the liquid level inside the liquid tank 14 is monitored, which makes it convenient for users to replenish the liquid inside the liquid tank 14 in a timely manner.

[0035] The drain nozzle 4 is equipped with an isolation cover 21. A filter screen 22 is installed in the middle of the isolation cover 21. The tail end of the drain nozzle 4 is connected to a drain valve 24. The drain valve 24 is connected to the other end of a drain pipe 23. The filter screen 22 in the middle of the isolation cover 21 plays a role in blocking particulate matter in the discharged liquid, thus preventing particulate matter from clogging the pipe.

[0036] The coke can 1 has mounting sleeves 25 fixed on both outer walls. Inside the mounting sleeves 25, there are support rings 27 for placing rotating sleeves 26. There are ball bearings 28 between the support rings 27 and rotating sleeves 26. The bottom of the mounting sleeves 25 is fixed with a first motor 29 by a bracket. The output shaft of the first motor 29 passes through the inside of the mounting sleeves 25 and is fixed to the bottom of the rotating sleeves 26. By setting the first motor 29 to rotate the rotating sleeves 26 inside the mounting sleeves 25, the first sealing cover 5 and the second sealing cover 6 will be moved to the outside of the coke can 1 by rotation during the process of loading material into the coke can 1, thereby avoiding the situation where the feed port is blocked and the material enters the coke can 1.

[0037] The rotating sleeve 26 has a multi-stage electric push rod 30 fixed inside. The top of the telescopic end of the multi-stage electric push rod 30 extends through to the top of the rotating sleeve 26 and is fixed to the bottom of the support block 31. The support block 31 has a relief cavity in the middle for driving the rack to move horizontally. A guide 32 is fixed in the middle of the relief cavity and is connected through the strip groove in the middle of the drive rack. Anti-collision pads 33 are fixed on both sides of the inside of the strip groove. The multi-stage electric push rod 30 plays a role in raising and lowering the first sealing cover 5 and the second sealing cover 6.

[0038] The second motor 34 is fixed to the back of the support block 31. The output shaft of the second motor 34 passes through the clearance groove at the upper end of the support block 31 and is fixed to the cylindrical gear 35. The outer side of the cylindrical gear 35 is engaged with the teeth of the drive rack 7. By setting the second motor 34 to cooperate with the cylindrical gear 35, the drive rack 7 is driven to move. When the drive rack 7 is driven to move, the first sealing cover 5 and the second sealing cover 6 will move closer or further away.
