Description

Technical Field

[0001] This utility model relates to the field of dry quenching technology, and more specifically, to a stable quenching mechanism for coking coal. Background Technology

[0002] Coke quenching is an essential process in coke production. Its main purpose is to cool red-hot coke to below 200 degrees Celsius. To meet higher environmental protection requirements, most coke quenching processes use dry quenching with inert gas as the heat exchange medium. However, existing coke quenching methods are intermittent, meaning that designated red-hot coke is placed into the quenching furnace for cooling and then discharged after a certain period of cooling. This method cannot perform continuous quenching operations and has low quenching efficiency. Utility Model Content

[0003] To address the above deficiencies, this utility model provides a stable quenching mechanism for coking coal, thus solving the aforementioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A stable quenching mechanism for prime coking coal includes inert cold air and red coke, comprising: an upper plate with a feed inlet and an air inlet. The lower plate has a discharge port; A side plate is provided between the upper plate and the lower plate, forming a circular cavity between the upper plate, the lower plate and the side plate; and exhaust holes are opened on the side plate. The baffle divides the circular cavity into multiple fan-shaped cavities, and the baffle drives the red coke from the inlet to the outlet for discharge. The inert cold air from the outside is discharged from the exhaust port through the air inlet, while carrying away the heat from the red-hot coals.

[0005] Furthermore, it also includes a fan-shaped air hood installed on the upper surface of the upper plate, the fan-shaped air hood covering the air inlet hole, forming a sealed cavity between the fan-shaped air hood and the upper plate, the feed port avoiding the position of the air inlet hole, and an air inlet channel installed on the fan-shaped air hood.

[0006] Furthermore, an annular gas collection hood is provided on the side surface of the side plate. The annular gas collection hood forms a sealed cavity around the side plate. The exhaust port extends from the inside to the outside and is in an upward position. An exhaust channel is installed on the annular gas collection hood.

[0007] Furthermore, the feed inlet is located at the upper end of one of the fan-shaped cavities, and the discharge outlet is located at the lower end of the adjacent fan-shaped cavity. The red coke enters the fan-shaped cavity through the feed inlet, moves at least 180 degrees, and is discharged from the discharge outlet.

[0008] Furthermore, a main shaft is provided between the upper plate and the lower plate, and a drive motor is installed on the surface of the lower plate. The rotating end of the drive motor drives the main shaft to rotate, and the partition is installed on the main shaft.

[0009] Furthermore, an inclined plate is installed between the partition and the main shaft.

[0010] The beneficial effects of this utility model are: by moving the partition, the red coke can be continuously moved in the circular cavity, and at the same time the coke is extinguished, so that the red coke can be continuously cooled down, which greatly improves the coke extinguishing efficiency. The design of the air inlet increases the contact area between the inert gas and the red-hot coke, thereby improving heat exchange efficiency; the design of the exhaust vent extending from the inside out and facing upwards prevents the exhaust vent from becoming blocked.

Detailed Implementation

[0012] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0013] This application provides a stable quenching mechanism for prime coking coal. Please refer to [reference needed]. Figures 1-5 Includes inert cold air 11 and red char 12; The upper plate 1 has a feed inlet 2 and an air inlet 3; The lower plate 4 has a discharge port 5; A side plate 6 is provided between the upper plate 1 and the lower plate 4, and a circular cavity 7 is formed between the upper plate 1, the lower plate 4 and the side plate 6. An exhaust hole 8 is opened on the side plate 6. The partition 9 divides the circular cavity 7 into multiple fan-shaped cavities. The partition 9 drives the red coke 12 from the feed port 2 to the discharge port 5 for discharge. The inert cold air 11 from the outside is discharged from the exhaust port 8 through the air inlet 3, while carrying away the heat from the red char 12.

[0014] In practical applications, the red coke 12 is moved to the position of the feed inlet 2 by the external conveying equipment. Under the action of gravity, it enters the current fan-shaped cavity through the feed inlet 2. Driven by the partition 9, the red coke 12 moves in a ring around the circular cavity 7 until it moves to the position of the discharge outlet 5. It falls at the position of the discharge outlet 5 by gravity. During the movement of the red coke 12, the inert cold air 11 from the outside enters the fan-shaped cavity through the air inlet 3. Under the action of air pressure, the inert cold air 11 will pass through the red coke 12 and be discharged from the exhaust port 8, taking away the heat of the red coke 12, thereby achieving the purpose of continuous coke extinguishing.

[0015] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 It also includes a fan-shaped air hood 21 installed on the upper surface of the upper plate 1. The fan-shaped air hood 21 covers the air inlet 3. A sealed cavity 22 is formed between the fan-shaped air hood 21 and the upper plate 1. The feed port 2 avoids the position of the air inlet 3. An air inlet channel 23 is installed on the fan-shaped air hood 21.

[0016] In practical applications, inert cold air 11 enters the fan-shaped air hood 21 through the air inlet channel 23 and enters the circular cavity 7 through the air inlet 3, which facilitates the cooling of the red coke 12. In order to avoid interference with the feed port 2, the air inlet 3 is separated from the feed port 2. The fan-shaped air hood 21 can continuously cool the moving red coke 12.

[0017] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The side plate 6 has an annular gas collection hood 31 on its side surface. The annular gas collection hood 31 forms a sealed cavity 32 around the side plate 6. The exhaust hole 8 extends from the inside to the outside and is in an upward position. An exhaust channel 33 is installed on the annular gas collection hood 31.

[0018] In practical applications, under the action of air pressure, the inert cold air 12 passes through the red char 12 and is discharged from the exhaust port 8. The exhaust port 8 is designed to extend from the inside to the outside, which facilitates ventilation while preventing the red char 12 from blocking the exhaust port 8. Finally, the air is concentrated in the annular gas collection hood 31 and discharged through the exhaust channel 33.

[0019] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The feed inlet 2 is located at the upper end of one of the fan-shaped cavities, and the discharge outlet 5 is located at the lower end of the adjacent fan-shaped cavity. The red coke 12 enters the fan-shaped cavity through the feed inlet 2, moves at least 180 degrees, and is discharged from the discharge outlet 5.

[0020] In practical applications, in order to improve the quenching effect, the setting of having the red coke 12 enter the fan-shaped cavity through the feed port 2 and move at least 180 degrees before being discharged from the discharge port 5 can effectively extend the moving distance of the red coke 12.

[0021] Reference Figure 1 A main shaft 51 is provided between the upper plate 1 and the lower plate 4. A drive motor 52 is installed on the surface of the lower plate 4. The rotating end of the drive motor 52 drives the main shaft 51 to rotate. A partition 9 is installed on the main shaft 51.

[0022] In practical applications, the drive motor 52 can drive the main shaft 51 and the partition 9 to rotate, thereby driving the red slag 12 to move.

[0023] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 An inclined plate 61 is installed between the partition 9 and the main shaft 51.

[0024] In practical applications, the inclined plate 61 can prevent the red-hot slag 12 at the root of the spindle 51 from being uncooled by the inert air 11.
