Description

Technical Field

[0001] This utility model belongs to the field of air volume ratio adjustment technology, specifically referring to a coke oven air volume ratio adjustment structure. Background Technology

[0002] In coke oven production, precise adjustment of the air intake is crucial for ensuring combustion efficiency, reducing energy consumption, and minimizing pollutant emissions. With increasingly stringent environmental standards in the steel industry and continuously rising energy costs, coke oven production places higher demands on the precision and response speed of the air intake system.

[0003] Traditional coke oven air intake systems mostly use mechanical dampers as air volume regulating devices. These devices control the air volume by manually or through simple electric adjustment of the damper opening. However, such dampers have significant limitations: on the one hand, the damper adjustment precision is low, making it difficult to meet the fine-grained air volume control requirements during coke oven combustion, which can easily lead to incomplete combustion or excessive air volume, resulting in energy waste and increased pollutant emissions; on the other hand, traditional adjustment methods rely on manual intervention or simple open-loop control, which cannot dynamically adjust the air intake volume according to the real-time operating conditions of the coke oven, resulting in significant adjustment lag, which seriously affects the stable operation and production efficiency of the coke oven. Utility Model Content

[0004] To address the aforementioned problems of low adjustment accuracy of the air damper in traditional coke ovens and the inability to dynamically adjust the air intake volume according to real-time operating conditions, this utility model provides a coke oven air intake volume ratio adjustment structure.

[0005] To achieve the above functions, the technical solution adopted by this utility model is as follows: a coke oven air intake ratio adjustment structure, including an air intake cylinder, wherein a fixed disc and a rotating disc are fixedly installed inside the air intake cylinder, and a plurality of ventilation hole groups are respectively opened on the fixed disc and the rotating disc, each ventilation hole group including a circular hole opened on the fixed disc and an overlapping hole opened on the rotating disc, a drive pull block is connected to the outer circumferential wall of the rotating disc, and an air volume adjustment mechanism is provided on the air intake cylinder;

[0006] The air volume adjustment mechanism includes an air volume sensor, a controller, and an adjustment cylinder. The air volume sensor is installed at the air outlet position on the inner side of the air inlet cylinder. The controller is fixed to the outer side wall of the air inlet cylinder. The adjustment cylinder is connected to the air inlet cylinder. The air volume sensor and the adjustment cylinder are respectively electrically connected to the controller.

[0007] As a preferred technical solution of this utility model, the ventilation hole group is evenly distributed in a ring with the central axis of the fixed disk and the rotating disk as the reference.

[0008] As a preferred technical solution of this utility model, the outer wall of the air inlet cylinder is provided with a cylinder mounting seat, the adjusting cylinder is fixed to the top of the cylinder mounting seat by bolts, and the piston rod end of the adjusting cylinder is connected to the drive pull block through a hinge seat.

[0009] As a preferred technical solution of this utility model, the two ends of the air inlet cylinder are provided with flanges, and the flanges are evenly distributed with multiple threaded mounting holes.

[0010] As a preferred technical solution of this utility model, the side wall of the air inlet cylinder is provided with an arc-shaped guide groove, and the drive block is slidably disposed in the arc-shaped guide groove, with its outer end extending through the outer surface of the air inlet cylinder.

[0011] As a preferred technical solution of this utility model, an annular mounting groove is provided on the inner side of the air inlet cylinder, the annular mounting groove is connected to the arc-shaped guide groove, and the rotating disk is rotatably installed in the annular mounting groove.

[0012] Compared with the prior art, the present invention achieves the following beneficial effects by adopting the above structure:

[0013] By coordinating a fixed disc, a rotating disc, circular holes, overlapping holes, a drive block, and an airflow regulation mechanism, the automated and precise regulation of the coke oven's airflow is achieved. The ventilation hole groups of the fixed and rotating discs change their overlapping area through rotation, allowing for adjustment of the ventilation cross-section. Compared to traditional damper regulation methods, this provides higher precision. The drive block is connected to the regulating cylinder in the airflow regulation mechanism. Under the real-time monitoring of the airflow sensor and the control of the controller, a closed-loop control system is formed. This system can dynamically adjust the airflow according to the coke oven's operating conditions, avoiding the lag of manual adjustment and improving combustion efficiency.

The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] like Figure 1-4 As shown, the present invention provides a coke oven air intake ratio adjustment structure, including an air intake cylinder 1. A fixed disc 2 and a rotating disc 3 are fixedly installed inside the air intake cylinder 1. The fixed disc 2 and the rotating disc 3 are tightly fitted together to ensure that there is no gap between them. Several sets of ventilation holes are respectively opened on the fixed disc 2 and the rotating disc 3. Each set of ventilation holes includes a circular hole 4 opened on the fixed disc 2 and an overlapping hole 5 opened on the rotating disc 3. By rotating the rotating disc 3, the overlapping area of ​​the overlapping hole 5 and the circular hole 4 changes, thereby adjusting the ventilation cross section to achieve air volume adjustment. A drive pull block 6 is connected to the outer circumferential wall of the rotating disc 3. An air volume adjustment mechanism 7 is provided on the air intake cylinder 1.

[0023] The airflow regulation mechanism 7 includes an airflow sensor 8, a controller 9, and a regulating cylinder 10. The airflow sensor 8 is installed at the air outlet on the inner side of the air inlet duct 1 to monitor the airflow in real time and transmit the signal to the controller 9. The controller 9 is fixed to the outer wall of the air inlet duct 1. Based on the signal from the airflow sensor 8, it determines whether the current airflow has reached the set value and outputs a control command to the regulating cylinder 10. The regulating cylinder 10 is connected to the air inlet duct 1. It receives the command from the controller 9 and drives the rotating disk 3 to rotate, adjusting the overlapping area of ​​the overlapping hole 5 and the circular hole 4, thereby realizing airflow regulation. The outer wall of the air inlet duct 1 is provided with a cylinder mounting seat 11. The regulating cylinder 10 is fixed to the top of the cylinder mounting seat 11 by bolts. The piston rod end of the regulating cylinder 10 is connected to the drive pull block 6 through a hinge seat for stable support of the regulating cylinder 10. The airflow sensor 8 and the regulating cylinder 10 are respectively electrically connected to the controller 9 to form a closed-loop control system to ensure the accuracy and stability of airflow regulation.

[0024] like Figure 1-4 As shown, the ventilation hole group is evenly distributed in a ring with the central axis of the fixed disk 2 and the rotating disk 3 as the reference, ensuring that the airflow is evenly dispersed after passing through the air volume adjustment mechanism 7, avoiding excessive or insufficient local air volume, thereby ensuring the stability and uniformity of combustion in the coke oven.

[0025] like Figure 1-3 As shown, flanges 12 are provided at both ends of the air inlet duct 1. Multiple threaded mounting holes are evenly distributed on the flanges 12. The flanges 12 are used to connect the air inlet duct 1 to other pipes or equipment. They are fixed with bolts through the evenly distributed threaded mounting holes to ensure the sealing and stability of the connection.

[0026] like Figure 1 and 2 As shown, an arc-shaped guide groove 13 is provided on the side wall of the air inlet cylinder 1 to guide the movement direction of the drive block 6. The drive block 6 is slidably fitted in the arc-shaped guide groove 13, and its outer end extends through the outer surface of the air inlet cylinder 1. The drive block 6 slides in the arc-shaped guide groove 13 to ensure that the rotation of the rotating disk 3 is stable and reliable.

[0027] like Figure 3 As shown, an annular mounting groove is provided on the inner side of the air inlet cylinder 1. The annular mounting groove is connected to the arc-shaped guide groove 13. The rotating disk 3 is rotatably installed in the annular mounting groove. The annular mounting groove provides mounting support for the rotating disk 3, allowing it to rotate flexibly around the axis, while limiting its axial and radial displacement, ensuring the accurate relative position of the rotating disk 3 and the fixed disk 2. The connection design between the annular mounting groove and the arc-shaped guide groove 13 allows the drive block 6 to smoothly drive the rotating disk 3 to rotate, realizing the function of air volume adjustment.

[0028] In practical use, the air inlet cylinder 1 is first fixedly connected to the coke oven ventilation duct using bolts via flange 12 to complete the installation of the device. During operation, the air volume sensor 8 monitors the air volume at the air outlet of the air inlet cylinder 1 in real time and transmits the data to the controller 9. After comparing the actual air volume with the preset value, the controller 9 sends a command to the regulating cylinder 10 if adjustment is required. The piston rod of the regulating cylinder 10 extends and retracts, driving the drive block 6 to slide along the arc-shaped guide groove 13 through the hinge seat, thereby driving the rotating disk 3 to rotate around the axis, changing the overlapping area of ​​the circular hole 4 of the fixed disk 2 and the overlapping hole 5 of the rotating disk 3, thereby realizing the adjustment of the ventilation section and the control of the air volume. When the coke oven operating conditions change, the system continuously adjusts the air volume dynamically through closed-loop control.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
