Description

Technical Field

[0001] This utility model relates to a coke pot for improving the efficiency of dry quenching, and belongs to the technical field of dry quenching production equipment. Background Technology

[0002] Dry quenching refers to a quenching method that uses inert gas to cool red-hot coke. CDQ is usually an abbreviation for dry quenching of coke. The coke undergoes a re-coking process in the pre-storage chamber of the dry quenching furnace. In addition, as it descends evenly and cools slowly with the discharge of coke, the coke has fewer cracks and better strength.

[0003] As a key piece of equipment in the dry quenching process, the coke pot directly affects the quenching efficiency and the stability of dry quenching operation. Existing coke pots suffer from uneven coke loading, resulting in uneven coke distribution within the dry quenching furnace. This causes drastic fluctuations in the boiler inlet temperature, leading to reduced quenching efficiency, increased energy consumption, and a significant impact on the quality of the cooled coke. Therefore, it is essential to improve the existing dry quenching coke pots. Utility Model Content

Multiple shaft sleeve fixing rods are evenly distributed around the outer circumference of the rotating shaft sleeve. The outer ends of the multiple shaft sleeve fixing rods are fixedly connected to the inner wall of the tank. Multiple stirring rods are connected around the outer circumference of the lower end of the rotating shaft. The upper end of the rotating shaft extends out of the bearing of the rotating shaft sleeve and is fixedly connected to the lower end of the drive shaft. Multiple fan blocks are connected around the outer circumference of the drive shaft.

[0007] The coke can described above, which can improve the efficiency of dry quenching, has a rectangular feed inlet on the top cover with stepped edges around it.

The inner cylinder is a conical cylinder with its central axis on the central axis of the top cover. The upper opening of the inner cylinder is larger than its lower opening. The circumference of the upper opening of the inner cylinder is fixedly connected to the top cover by bolts. The lower opening of the inner cylinder surrounds the lower end of the drive shaft. Multiple fan blocks surround the outer circumference of the drive shaft on the inner cylinder wall. The multiple fan blocks are connected to the drive shaft by rotating rods. The fan blocks are teardrop-shaped. There are air guide grooves on the opposite side walls of the inner cylinder. The length of the air guide grooves is along the diameter of the conical cylinder of the inner cylinder, and the air guide grooves are opposite to the fan blocks.

[0009] The aforementioned coke canister, which can improve the efficiency of dry quenching, has connecting rods evenly distributed around the lower outer circumference of the rotating shaft.

[0021] Figure 1 , 2As shown, the tank body 1 is a cylindrical body. Multiple support legs 2 are evenly distributed on the lower outer wall of the tank body 1. The upper outer wall of the support legs 2 has elongated holes along the length of the support legs 2. Fixing bolts are used to fix the support legs 2 to the tank body 1 through the elongated holes.

[0022] Figure 1 , 2 The tank body 1 is shown to have a top cover 3 fixed to its top, and an exhaust pipe 4 is installed in the center of the top cover 3. The exhaust pipe 4 discharges the hot steam inside the tank body 1. A discharge cylinder 7 is installed in the center of the bottom surface of the tank body 1, and the coke after quenching is discharged from the discharge cylinder 7.

[0023] Figure 1 , 2 The display shows that there is a feed inlet 5 on one side of the top cover 3, and a cover plate 6 covers the feed inlet 5. The feed inlet 5 is rectangular with stepped edges. The cover plate 6 is a rectangular plate, and the edge of the cover plate 6 matches the upper edge of the stepped edges of the feed inlet 5. The cover plate 6 is placed within the stepped edges of the feed inlet 5. There are downward slots on the stepped edges at both ends of the feed inlet 5. Vertical inserts 17 are welded to both ends of the lower surface of the cover plate 6, and the inserts 17 on the lower surface of the cover plate 6 are inserted into the slots on the stepped edges of the feed inlet 6. Vertical lifting handles 18 are welded to both ends of the upper surface of the cover plate 6. In use, lifting the lifting handles 18 opens the cover plate 6, allowing hot coke to be fed into the tank 1 from the feed inlet 5.

[0024] Figure 1 , 2 The display shows that there is a ring-shaped air inlet pipe 8 below the bottom surface of the tank body 1. Multiple air inlets 22 are evenly distributed on the bottom surface of the tank body 1, and multiple vent pipes 23 are evenly distributed around the bottom surface of the tank body 1. The upper end of the vent pipe 23 is connected to the air inlet hole 22 on the bottom surface of the tank body 1, and the lower end of the vent pipe 23 is connected to the circumference of the air inlet pipe 8. The air inlet end of the air inlet pipe 8 is connected to the air supply pipeline. Cooling gas is transported from the bottom surface of the tank body 1 into the tank body 1 through the air supply pipeline, the air inlet pipe 8, and the vent pipes 23.

[0025] Figure 1 , 2The display shows that there is a rotating shaft 10 inside the tank 1. The lower end of the rotating shaft 10 is connected to the bottom surface of the tank 1 via a bearing, and the upper end of the rotating shaft 10 is rotatably connected to a bearing inside a rotating bushing 11. Multiple bushing fixing rods 12 are evenly distributed around the outer circumference of the rotating bushing 11, and the outer ends of the multiple bushing fixing rods 12 are respectively fixedly connected to the inner wall of the tank 1. Connecting rods 21 are evenly distributed around the outer circumference of the lower end of the rotating shaft 10. The connecting rods 21 are L-shaped rods, and the outer ends of the multiple connecting rods 21 are respectively connected to multiple stirring rods 13. The stirring rods 13 are round rods, and the length direction of the round rods 13 is along the diameter direction of the bottom surface of the tank 1. The outer circumference of the stirring rods 13 is located above the bottom inner wall of the tank 1, and there is a gap between the outer circumference of the stirring rods 13 and the bottom inner wall of the tank 1. When the rotating shaft 10 rotates, it drives multiple stirring rods 13 to rotate through multiple connecting rods 21. The stirring rods 13 stir the coke in the tank 1, so that the hot coke can be better mixed with the cooling gas for heat exchange, thereby realizing the coke quenching operation.

[0026] Figure 1 , 2 The drive shaft 14 drives the rotation of the rotating shaft 10. The upper end of the rotating shaft 10 extends from the bearing of the rotating bushing 11 and is fixedly connected to the lower end of the drive shaft 14. One end of a plurality of rotating rods 15, which are evenly distributed, is fixedly connected to the outer circumference of the drive shaft 14. A plurality of fan blocks 16 are fixedly connected to the other end of the rotating rods 15. The fan blocks 16 are teardrop-shaped and are driven to rotate by the hot steam.

[0027] Figure 1 , 2 The fan blocks 16 are enclosed by an inner cylinder 19. The inner cylinder 19 is located below the top cover 3 of the tank body 1. The inner cylinder 19 is a conical cylinder, with its central axis aligned with the central axis of the top cover 3. The upper opening of the inner cylinder 19 is larger than its lower opening. The circumference of the upper opening of the inner cylinder 19 is fixedly connected to the top cover 3 by bolts. The lower opening of the inner cylinder 19 surrounds the lower end of the drive shaft 14. Multiple fan blocks 16 are enclosed on the outer circumference of the inner cylinder wall surrounding the drive shaft 14. Air guide grooves 20 are located on opposite side walls of the inner cylinder 19, with their lengths aligned with the diameter of the conical cylinder. The air guide grooves 20 are opposite to the fan blocks 16. Hot steam from the tank body 1 enters the inner cylinder 19 through the air guide grooves 20 on both sides. The air guide grooves 20 concentrate the hot steam, giving the gas greater kinetic energy, which can then drive the fan blocks 14.

[0028] Figure 3 , 4The present invention also includes a scraper 25 for scraping away the red-hot coke residue on the inner wall of the tank 1, thereby achieving self-cleaning of the tank. The structure is as follows: a top rod 24 is connected to one end of the stirring rod 13 facing the tank wall; the rear end of the top rod 24 is vertically fixed to the center of the end face of the stirring rod 13; the front end of the top rod 24 is connected to the lower end of the scraper 25; the scraper 25 is placed vertically and contacts the inner wall of the tank 1, with a sliding fit between the scraper 25 and the inner wall of the tank 1.

[0029] Figure 3 The top rod 24 and scraper 25 are made of hard, high-temperature resistant steel. The scraper 25 is in close contact with the inner wall of the tank 1 to scrape off the red-hot coke residue.

[0030] Figure 4 The top rod 24 and scraper 25 are made of elastic high-temperature resistant steel, and multiple convex balls 26 are fixedly connected to the inner wall of the bottom circumference of the tank 1 at equal intervals. When the top rod 24 and scraper 25 perform scraping operations, the elastic scraper 25 repeatedly collides with the convex balls 26 on the inner wall of the tank 1, causing the scraper 25 to continuously tap the inner wall of the tank 1, which enhances the cleaning of the inner wall of the tank 1 while also cleaning the scraper 25 itself.

[0031] The usage process of this utility model is as follows:

[0032] In use, by pulling the handle 18 to lift the insert plate 17 and the cover plate 6, the red-hot coke can be added into the tank 1 through the feed port 5. At the same time, cooling gas is filled into the tank 1 through the air inlet pipe 8. The air inlet pipe 8 will evenly distribute the cooling gas to multiple air pipes 23 and spread it to the bottom of the tank 1. The cooling gas exchanges heat with the red-hot coke at the bottom of the tank 1, thereby achieving the effect of cooling and quenching the red-hot coke.

[0033] During the heat exchange process, the high-temperature steam generated inside the tank 1 enters the exhaust pipe 4 at the top of the tank 1 through the inner cylinder 19 and is discharged. As the high-temperature steam rises, it impacts the surface of the fan block 16 through the guide groove 15 on the side wall of the inner cylinder 1. Due to the teardrop columnar structure of the fan block 16, the fan block 16 can obtain a large thrust. The fan block 16 moves under the action of steam thrust. The fan block 16 drives the drive shaft 14 to rotate in a fixed direction, thereby driving the rotating shaft 10 to rotate. The rotating shaft 10 drives the stirring rod 13 to rotate through the connecting rod 21, which accelerates the mixing of the red-hot coke and the cooling gas and enhances the coke quenching effect.
