Description

Technical Field

[0001] The utility model relates to the technical field of coke quenching equipment, in particular to an anti-static filtering device for dry coke quenching. Background Technique

[0002] Dry coke quenching is a method of cooling red coke with inert gas. During dry coke quenching, red coke is charged from the top of the dry coke quenching furnace, and low-temperature inert gas is blown into the red coke layer in the cooling chamber of the dry coke quenching furnace by a circulating fan to absorb the heat of the red coke. The cooled coke is discharged from the bottom of the dry coke quenching furnace. The high-temperature inert gas coming out of the annular flue of the dry coke quenching furnace exchanges heat through a dry coke quenching boiler, and steam is generated by the boiler. The cooled inert gas is re-blown into the dry coke quenching furnace by the circulating fan for recycling. Dry coke quenching is superior to wet coke quenching in terms of energy conservation, environmental protection and improving coke quality. However, as the use time of the filter screen continues to increase, a large amount of coke powder will accumulate on the surface of the filter screen, resulting in a decrease in the filtering effect of the filter screen. Therefore, it is necessary to clean the filter screen regularly. When cleaning the filter screen in the existing device, the filter screen needs to be disassembled. After cleaning, the filter screen also needs to be installed in the dust removal box, and the operation is relatively troublesome.

DETAILED DESCRIPTION

[0020] The utility model is further described in detail below through the drawings and embodiments.

[0021] like Figures 1-4As shown: An anti-static filtering device for dry quenching coke includes a main filtering tank 1. An inclined guiding slope 7 is provided inside the main filtering tank 1. The bottom of the guiding slope 7 is connected to the side wall of the main filtering tank 1 and a filtering component is arranged inside. There are two guiding slopes 7. A filtering plate 5 is connected between the two guiding slopes 7. Both sides of the filtering plate 5 extend into the bottom of the guiding slope 7, and holes are provided at the bottom of the guiding slope 7 so that the shock column 12 can strike on the filtering plate 5. A filtering tank 6 is provided directly below the filtering plate 5. The driving motor 8 drives the connecting rod 9 to rotate, thereby driving the rotating disk 19 to rotate. Two protruding cross bars are arranged on the rotating disk 19. As the rotating disk 19 rotates, it presses against the fixed column 13 and drives it to rotate, thereby driving the connecting column 14 to perform a circular motion. When rotating 180 degrees clockwise, the displacement column 18 and the shock column 12 rise, and the spring 17 contracts. When the rotation exceeds 180 degrees, the fixed column 13 is on the right side of the rotating disk 19 without the cross bar for limiting. Under the action of the spring 17 expanding, the displacement column 18 and the shock column 12 move downward, completing one strike on the filtering plate 5. Repeating this multiple times knocks off the coke powder on it to achieve cleaning.

[0022] The filtering component includes a driving motor 8, a connecting rod 9, a rotating disk 19, a fixed column 13, a connecting column 14, and a displacement column 18. The output end of the driving motor 8 is connected to the connecting rod 9. The end of the connecting rod 9 passes through the limiting plate 11 and is connected to the rotating disk 19. A hollow circular tube is provided on the limiting plate 11. The part of the connecting rod 9 passing through the limiting plate 11 is located inside the circular tube and is connected to the rotating disk 19. A rotating ring is sleeved on the hollow circular tube and is located behind the rotating disk 19.

[0023] A rotating ring is connected behind the rotating disk 19. A connecting column 14 is fixedly connected to the rotating ring. A fixed column 13 is fixedly provided above the connecting column 14. The fixed column 13 protrudes outward to be at the same horizontal plane as the cross bar on the rotating disk 19. When the rotating disk 19 rotates, the cross bar presses against the fixed column 13 and drives it to rotate together.

[0024] The end of the connecting column 14 is connected to a connecting piece 15. A displacement column 18 is connected to the connecting piece 15. Two fixing plates 10 are fixedly provided on the limiting plate 11.

[0025] A limiting ring sleeve 16 is fixedly arranged between the two fixing plates 10. A spring 17 is arranged inside the limiting ring sleeve 16. One end of the spring 17 is fixedly fixed on the upper fixing plate 10, and the other end is fixed on the bottom end of the displacement column 18. When the displacement column 18 rises, the spring 17 contracts, providing force for the subsequent reset of the displacement column 18.

[0026] A dust removal device 3 is connected to the side wall of the main body 1 of the filter tank. An exhaust pipe 2 is provided below the dust removal device 3 and is connected to the inside of the main body 1 of the filter tank. High-temperature inert gas is discharged from the exhaust pipe 2. An air inlet pipe 4 is also connected to the side wall of the main body 1 of the filter tank. Low-temperature gas enters from the air inlet pipe 4, and the gas entering from the air inlet pipe 4 is in a spray shape, increasing the humidity inside the main body 1 of the filter tank and playing a role in preventing static electricity.

[0027] As described above, based on the embodiments, through the above description, relevant staff can completely make various changes and modifications without departing from the spirit of the present invention.
