[0002] The gate device refers to a device used to control the flow of flue gas in the coke oven flue. The gate device has the characteristics of simple structure and reliable opening and closing, and is widely used in the coking industry.

[0003] Among the related technologies, a Chinese patent with authorization publication number CN212954834U provides a flue damper device comprising a channel steel frame with a bearing seat mounted on top. A rotating shaft is mounted on the bearing seat, passing through the channel steel frame and connected to a damper. The channel steel frame is mounted between two opposing coke oven flue sections. The damper slides along the channel steel frame to control the opening and closing of the coke oven flue.

[0004] In the process of implementing this application, the inventors found that there are at least the following problems in this technology: when the channel steel frame is installed between two relatively arranged coke oven flues, the width of the channel steel frame is not easy to adjust to the width between the two relatively arranged coke oven flues, making it inconvenient to install the gate device between coke oven flues with different spacings, resulting in a small scope of application of the gate device. Utility Model Content

[0005] In order to facilitate the installation of the gate device on the coke oven flue and expand the application scope of the gate device, the present application provides a coke oven flue gate device.

[0006] The coke oven flue damper device provided in this application adopts the following technical solution:

[0007] A coke oven flue damper device comprises a damper body, mounting frames are provided above and below the damper body, movable frames are fixedly provided on opposite surfaces of the mounting frames, a fixed frame is provided on the movable frames, a clearance groove is provided on one side of the fixed frame, the damper body is inserted into the clearance groove, the damper body is used to seal the fixed frame, a telescopic assembly is provided on the mounting frame, the telescopic assembly is connected to the other side of the fixed frame, and the telescopic assembly is used to drive the mounting frame to move.

[0008] By adopting the above technical solution, when the gate device is installed between the coke oven flues, the installation frame is moved by the telescopic assembly according to the distance between the coke oven flues. When the distance between the installation frames is moved to an appropriate distance, the installation frame is correspondingly installed on the coke oven flue, so that the gate device is installed on the coke path flue. When the gate device is installed on the coke path flue, the through holes between the installation frame, the movable frame and the fixed frame connect the coke path flue, and the effect of controlling the flow of flue gas is achieved by sliding the gate body. The installation frame is driven to move by the telescopic assembly, so that the relatively arranged installation frames are relatively moved, thereby achieving the effect of adjusting the distance between the installation frames. At the same time, during the movement of the installation frame, the installation frame drives the movable frame to move relatively along the fixed frame, and the fixed frame is always mounted on the movable frame, thereby achieving the effect of adjusting the overall length of the gate device, so that the gate device is easy to install between coke oven flues with different spacings, thereby achieving the effect of expanding the scope of application of the gate device.

[0009] Preferably, a plurality of mounting bolts are provided through the mounting frame.

[0010] By adopting the above technical solution, the mounting frame and the coke oven flue are locked together by mounting bolts.

[0011] Preferably, a support frame is fixedly provided on one side of the fixed frame, a piston cylinder is fixedly provided on the support frame, an output shaft of the piston cylinder faces the give way groove, and the output shaft of the piston cylinder is fixedly connected to the gate body.

[0012] By adopting the above technical solution, the output shaft of the piston cylinder drives the gate body to move. During the retraction of the output shaft of the piston cylinder, the gate body gradually moves toward the outside of the fixed frame along the give way groove. During the extension of the output shaft of the piston cylinder, the gate body gradually moves toward the inside of the fixed frame along the give way groove. When the gate body abuts against the inner wall of the fixed frame, the gate body cuts off the flue gas.

[0013] Preferably, the telescopic assembly includes a telescopic seat, a telescopic cylinder and a telescopic screw, one end of the telescopic screw is fixedly connected to the mounting frame, the other end of the telescopic screw is inserted into the telescopic cylinder, the telescopic screw is threadedly connected to the telescopic cylinder, the telescopic cylinder passes through the telescopic seat, the telescopic cylinder is rotatably connected to the telescopic seat, and the telescopic seat is fixedly connected to the side wall of the fixed frame.

[0014] By adopting the above technical solution, the telescopic cylinder is rotated, and the telescopic screw moves along the telescopic cylinder, so that the telescopic screw drives the installation frame to move.

[0015] Preferably, a fixed adjustment button is provided between the telescopic cylinders.

[0016] By adopting the above technical solution, when the adjustment knob is rotated, the adjustment knob drives the telescopic screw rod to rotate synchronously, so that the installation frames move away from each other or close to each other synchronously, achieving the effect of quickly adjusting the distance between the installation frames.

[0017] Preferably, a guide seat is fixedly arranged on the side wall of the fixed frame. A guide cylinder and a guide rod are arranged between the guide seat and the installation frame. One end of the guide rod is inserted into the guide cylinder, the outer end of the guide rod outside the guide cylinder is fixedly connected with the installation frame, and the end of the guide cylinder away from the installation frame is fixedly connected with the guide seat.

[0018] By adopting the above technical solution, during the movement of the installation frame, the guide rod moves along the guide sleeve, improving the stability of the movement of the installation frame.

[0019] Preferably, a group of limit frames are fixedly arranged in the fixed frame. Limit rubber pads are fixedly arranged on the opposite surfaces of the limit frames. The gate plate body is arranged between the limit rubber pads, and the gate plate body is attached to the limit rubber pads.

[0020] By adopting the above technical solution, the gate plate body is slidably arranged between the limit frames, improving the stability of the movement of the gate plate body. Since the gate plate body is attached to the limit rubber pads, when the gate plate body moves, the limit rubber pads clean the surface of the gate plate body. When the gate plate body abuts against the inner wall of the fixed frame, flue gas is not likely to flow through the gap between the gate plate body and the limit frame, improving the sealing effect of the gate plate body on the fixed frame.

[0021] Preferably, a sealing layer is fixedly arranged on the outer wall of the moving frame, and the opposite surfaces of the moving frame and the fixed frame are both attached to the sealing layer.

[0022] By adopting the above technical solution, the sealing layer is filled between the moving frame and the fixed frame, reducing the situation of flue gas escaping from between the moving frame and the fixed frame to the outside.

Detailed implementation manners

[0032] The following further Figures 1-4 describes the present application in detail.

[0033] The embodiment of the present application discloses a coke oven flue damper device. Refer to Figure 1 and Figure 2, including a gate plate body 1, mounting frames 2 are installed above and below the gate plate body 1, and a number of mounting bolts 21 are penetrated through the mounting frames 2. Opposite surfaces of the mounting frames 2 are both installed with moving frames 3, and a fixed frame 4 is sleeved on the moving frames 3 together. The moving frames 3 can slide relative to the fixed frame 4. Telescopic components 5 are installed on opposite surfaces of the mounting frames 2, and the telescopic components 5 are connected to one side of the fixed frame 4. The telescopic components 5 are used to drive the mounting frames 2 to move. A relief groove 41 is opened on the other side of the fixed frame 4, and the gate plate body 1 is inserted into the relief groove 41, and the gate plate body 1 is used to seal the fixed frame 4. A support frame 71 is welded on the side wall of the fixed frame 4, and a piston cylinder 7 is installed on the support frame 71. The output shaft of the piston cylinder 7 faces the relief groove 41, and the output shaft of the piston cylinder 7 is welded to the gate plate body 1. When installing the gate plate device between the coke oven flues, according to the distance between the coke oven flues, the mounting frames 2 are moved through the telescopic components 5. When the distance between the mounting frames 2 is moved to a suitable distance, the mounting frames 2 and the coke oven flues are locked together through the mounting bolts 21, so that the gate plate device is installed on the coke oven flues. After the gate plate device is installed on the coke oven flues, the through holes between the mounting frames 2, the moving frames 3 and the fixed frame 4 conduct the coke oven flues. By controlling the expansion and contraction of the output shaft of the piston cylinder 7 to drive the sliding of the gate plate body 1, the effect of controlling the flue gas flow is achieved. During the retraction process of the output shaft of the piston cylinder 7, the gate plate body 1 gradually moves out of the fixed frame 4 along the relief groove 41; during the extension process of the output shaft of the piston cylinder 7, the gate plate body 1 gradually moves into the fixed frame 4 along the relief groove 41; when the gate plate body 1 abuts against the inner wall of the fixed frame 4, the gate plate body 1 cuts off the flue gas. By driving the movement of the mounting frames 2 through the telescopic components 5, the opposite mounting frames 2 move relative to each other, so as to achieve the effect of adjusting the distance between the mounting frames 2. At the same time, during the movement of the mounting frames 2, the mounting frames 2 drive the moving frames 3 to move relative to the fixed frame 4, and the fixed frame 4 is always sleeved on the moving frames 3, so as to achieve the effect of adjusting the overall length of the gate plate device, making the gate plate device easy to install between coke oven flues with different spacings, and achieving the effect of expanding the application range of the gate plate device.

[0034] In order to achieve the effect of driving the movement of the mounting frames 2, refer to Figure 2 and Figure 3, the telescopic assembly 5 includes a telescopic base 51, a telescopic cylinder 52, and a telescopic screw 53. The telescopic base 51 is fixedly installed on the side wall of the fixed frame 4, and the telescopic cylinder 52 penetrates through the telescopic base 51. The telescopic cylinder 52 is rotatably connected to the telescopic base 51, and an adjustment knob 6 is installed between the telescopic cylinders 52. One end of the telescopic screw 53 is welded to the installation frame 2, and the other end of the telescopic screw 53 is inserted into the telescopic cylinder 52, and the telescopic screw 53 is threadedly connected to the telescopic cylinder 52. Rotating the adjustment knob 6 drives the telescopic screw 53 to rotate synchronously, causing the telescopic screw 53 to move along the telescopic cylinder 52. Thus, the telescopic screw 53 drives the installation frames 2 to move away from or close to each other synchronously, achieving the effect of quickly adjusting the distance between the installation frames 2.

[0035] To enable the stable movement of the installation frame 2, refer to Figure 2 and Figure 4 , a guide seat 8 is installed on the side wall of the fixed frame 4, and a guide cylinder 81 and a guide rod 82 are installed between the guide seat 8 and the installation frame 2. One end of the guide rod 82 is welded to the installation frame 2, the other end of the guide rod 82 is inserted into the guide cylinder 81, and the guide cylinder 81 is welded to the guide seat 8. During the movement of the installation frame 2, the guide rod 82 moves along the guide sleeve, improving the stability of the movement of the installation frame 2.

[0036] To enable the stable movement of the gate plate body 1, refer to Figure 3 and Figure 4 , a group of limit frames 9 are installed in the fixed frame 4, and the gate plate body 1 is arranged between the limit frames 9. During the movement of the gate plate body 1, the limit frames 9 restrict the gate plate body 1 from moving in other directions, thereby improving the stability of the movement of the gate plate body 1.

[0037] For the sealing effect of the gate plate body 1 on the fixed frame 4, refer to Figure 3 and Figure 4 , limit rubber pads 91 made of rubber material are installed on the opposite surfaces of the limit frames 9, the gate plate body 1 is inserted between the limit rubber pads 91, and the gate plate body 1 is in contact with the limit rubber pads 91. When the gate plate body 1 abuts against the inner wall of the fixed frame 4, since the gate plate body 1 is in contact with the limit rubber pads 91, it makes it difficult for flue gas to flow through the gap between the gate plate body 1 and the limit frames 9. When the gate plate body 1 moves, the limit rubber pads 91 clean the surface of the gate plate body 1.

[0038] To prevent flue gas from escaping to the external environment easily, refer to Figure 3 and Figure 4 , a sealing layer 31 made of rubber material covers the outer wall of the moving frame 3, and the opposite surfaces of the moving frame 3 and the fixed frame 4 are both in contact with the sealing layer 31. The sealing layer 31 fills the space between the moving frame 3 and the fixed frame 4, reducing the situation of flue gas escaping from between the moving frame 3 and the fixed frame 4 to the outside.

[0039] The implementation principle of a coke oven flue damper device in an embodiment of the present application is as follows: When installing the damper device between the coke oven flues, according to the distance between the coke oven flues, the installation frame 2 is moved by rotating the adjustment knob 6. When the distance between the installation frames 2 is moved to an appropriate distance, the installation frame 2 and the coke oven flue are locked together through the installation bolts 21, so that the damper device is installed on the coke oven flue. After the damper device is installed on the coke oven flue, the through holes between the installation frame 2, the moving frame 3, and the fixed frame 4 conduct the coke oven flue. By controlling the expansion and contraction of the output shaft of the piston cylinder 7 to drive the sliding damper body 1, the effect of controlling the flue gas flow is achieved. During the retraction process of the output shaft of the piston cylinder 7, the damper body 1 gradually moves outward from the fixed frame 4 along the relief groove 41; during the extension process of the output shaft of the piston cylinder 7, the damper body 1 gradually moves inward from the fixed frame 4 along the relief groove 41; when the damper body 1 abuts against the inner wall of the fixed frame 4, the damper body 1 cuts off the flue gas. By rotating the adjustment knob 6 to drive the movement of the installation frame 2, the relatively arranged installation frames 2 move relative to each other, so as to achieve the effect of adjusting the distance between the installation frames 2. During the movement of the installation frame 2, the installation frame 2 drives the moving frame 3 to move relative to the fixed frame 4, and the fixed frame 4 is always sleeved on the moving frame 3, so as to achieve the effect of adjusting the overall length of the damper device, making the damper device easy to install between coke oven flues with different spacings, and achieving the effect of expanding the application range of the damper device.

[0040] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited by this. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
