[0001] This utility model relates to the field of switch technology, and in particular to a waste gas switch for coke ovens. Background Technology

[0002] The coke oven exhaust gas switch is an important component of coke oven equipment, located between the coke oven's main flue and branch flue. Its main function is to control the direction and flow rate of the exhaust gas, ensuring the normal operation and heating effect of the coke oven. The exhaust gas switch regulates the exhaust gas by precisely controlling the opening and closing of the valve. During the coke oven heating process, according to process requirements and changes in oven conditions, the exhaust gas switch can adjust the amount of air entering the main flue to control the combustion rate and temperature distribution within the coke oven.

[0003] In most existing exhaust gas switch devices, the exhaust gas inlet is fixed by bolts. When the exhaust gas inlet needs to be disassembled, replaced, or maintained during use, the exposed bolts are prone to corrosion, which will affect the disassembly work of the workers.

[0004] Therefore, it is necessary to provide a new waste gas switch for coke ovens to solve the above-mentioned technical problems. Summary of the Invention

[0008] The pin assembly includes a support plate and a rotating cylinder. Two support plates are provided and symmetrically distributed on both sides of the support column. Staggered insert rods are fixedly installed on the opposite surfaces of the two support plates. The rotating cylinder is rotatably installed inside the support column. Threaded movable rods are inserted on both sides inside the rotating cylinder, and the thread directions of the threaded structures on both sides are opposite. The end of the movable rod away from the rotating cylinder is fixedly connected to the side wall of the corresponding support plate.

[0009] Preferably, the exhaust gas switch body is equipped with a cleaning assembly for cleaning the side walls of the exhaust gas chamber.

[0010] The cleaning assembly includes a support frame, inside which is a rotating ring that is rotatably connected. Multiple annularly distributed cleaning strips are fixedly installed on the inner wall of the rotating ring, and the outer wall of the cleaning strips abuts against and is rotatably connected to the side wall of the exhaust gas sump.

[0011] Preferably, a vertical rod is fixedly installed on one side inside the support frame, and a drive rod is rotatably installed on the other side inside the support frame. The top ends of both the vertical rod and the drive rod extend to the top of the exhaust gas switch body. A top plate is fixedly installed on the top end of the vertical rod. The top plate is rotatably connected to the drive rod. The bottom of the top plate is fixedly connected to the top of the exhaust gas switch body, and a motor for driving the drive rod is fixedly installed on the top of the top plate.

[0012] Preferably, a linkage gear is fixedly installed on the outer wall of the rotating ring, and a drive gear is fixedly installed on the outer wall of the drive rod at the position opposite to the linkage gear, and the drive gear meshes with the linkage gear.

[0013] Preferably, the pin assembly further includes mounting pieces, two of which are fixedly mounted on opposite side walls of the support column, and guide telescopic rods are fixedly mounted between the two mounting pieces and the corresponding support pieces.

[0014] Preferably, the two support plates have rotatable connecting mounting rings on the opposite sides of the moving rod, and support rings are fixedly installed on both sides of the outer wall of the rotating cylinder. Multiple evenly distributed limiting telescopic rods are fixedly mounted between the support rings and the mounting rings, and a telescopic protective cover is fixedly mounted on the outside of the multiple limiting telescopic rods between the support rings and the mounting rings.

[0015] Preferably, guide rods are fixedly installed on both sides inside the support frame. Symmetrically distributed lead screws are rotatably installed between the two guide rods inside the support frame. A motor driving the lead screws is fixedly installed on the top of the support frame. A movably connected adapter plate is provided between the lead screw and the guide rod on the same side. The inner wall of the adapter plate abuts against and slides against the outer wall of the guide rod. The inner wall of the adapter plate is threadedly connected to the outer wall of the lead screw.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0030] Please refer to Figures 1 to 6. This embodiment of the present invention provides a waste gas switch for a coke oven.

[0031] The furnace exhaust gas switch includes: exhaust gas switch body 1.

[0032] In an embodiment of this utility model, please refer to Figures 1 to 6. An exhaust gas counterweight 2 is movably suspended inside the exhaust gas switch body 1. A support assembly 3 for mounting the exhaust gas counterweight 2 is provided on the exhaust gas switch body 1, and a pin assembly 4 for pin-limiting the exhaust gas counterweight 2 is mounted inside the exhaust gas switch body 1. The support assembly 3 includes a support frame 31, which is fixedly installed on the top of the exhaust gas switch body. A support column 33 for suspending the exhaust gas counterweight 2 is movably installed inside the support frame 31. The pin assembly 4 includes support plates 41 and a rotating cylinder 42. Two support plates 41 are provided and symmetrically distributed on both sides of the support column 33. Alternating insert rods 411 are fixedly installed on the opposite surfaces of the two support plates 41. The rotating cylinder 42 is rotatably installed inside the support column 33, and threaded moving rods 421 are inserted into both sides of the rotating cylinder 42. Furthermore, the thread directions of the threaded structures on both sides are opposite, and the end of the moving rod 421 away from the rotating cylinder 42 is fixedly connected to the side wall of the corresponding support plate 41. The side wall of the exhaust gas switch body 1 and the part opposite to the exhaust gas ball 2 are provided with a side door that is rotatably connected by a hinge.

[0033] It should be noted that by fixing the exhaust gas weight 2 by inserting it, when it is necessary to disassemble and repair the exhaust gas weight 2 during subsequent use, the rotating cylinder 42 in the pin assembly 4 can be controlled to rotate, and the rotating cylinder 42 will drive the insert rod 411 to move out of the docking cylinder 331 and the weight rod 21 through the moving rod 421 and the support plate 41. This will release the limit between the weight rod 21 and the docking cylinder 331, and then the weight rod 21 can be pulled down to complete the disassembly of the exhaust gas weight 2. The entire disassembly is more convenient. Compared with the traditional bolt fixing method, the operation is simpler and has fewer steps, which makes it more convenient for the staff to carry out subsequent inspection and maintenance.

[0034] In an embodiment of this utility model, please refer to Figures 1 to 6. A cleaning assembly 5 for cleaning the sidewalls of the exhaust gas impeller 2 is installed inside the exhaust gas switch body 1. The cleaning assembly 5 includes a support frame 51. Inside the support frame 51, a rotating ring 53 is rotatably connected. Multiple annularly distributed cleaning strips 531 are fixedly installed on the inner wall of the rotating ring 53, and the outer walls of the cleaning strips 531 abut against and are rotatably connected to the sidewalls of the exhaust gas impeller 2. A vertical rod 511 is fixedly installed on one side inside the support frame 51, and a drive rod 52 is rotatably installed on the other side inside the support frame 51. The top ends of both the vertical rod 511 and the drive rod 52 extend to the top of the exhaust gas switch body 1. A top plate 512 is fixedly installed on the top end of the vertical rod 511, and the top plate 512 is rotatably connected to the drive rod 52. The bottom of the top plate 512 is fixedly connected to the top of the exhaust gas switch body 1. A motor for driving the drive rod 52 is fixedly installed on the top of the rotating ring 53. A linkage gear 54 is fixedly installed on the outer wall of the rotating ring 53. A drive gear 521 is fixedly installed on the outer wall of the drive rod 52 at the position opposite to the linkage gear 54, and the drive gear 521 meshes with the linkage gear 54.

[0035] It should be noted that the cleaning strip 531 is made of rubber, and therefore, during use, when the drive rod...

[0036] When the 52 rotates, it drives the cleaning strip 531 to rotate through the meshing of the drive gear 521 and the linkage gear 54. This allows the cleaning strip 531 to smoothly pass through and abut against the outer wall of the exhaust gas cylinder 2, thereby scraping and cleaning its outer wall. This reduces the impact of impurities adhering to the outer wall of the exhaust gas cylinder 2 on the subsequent sealing effect.

[0037] In the embodiments of this utility model, please refer to Figures 1 to 6. The pin assembly 4 further includes mounting plates 43. Two mounting plates 43 are provided and fixedly installed on the opposite side walls of the support column 33. Guide telescopic rods 431 are fixedly mounted between the two mounting plates 43 and the corresponding support plates 41. Rotary connecting mounting rings 6 are provided at the opposite positions of the side walls of the two support plates 41 and the moving rod 421. Support rings 63 are fixedly installed on both sides of the outer wall of the rotating cylinder 42. Multiple evenly distributed limiting telescopic rods 61 are fixedly mounted between the support rings 63 and the mounting rings 6. Telescopic protective covers 62 are fixedly connected to the outside of the multiple limiting telescopic rods 61 between the support rings 63 and the mounting rings 6.

[0038] It should be noted that: Due to the telescopic protective cover 62, during use, the area located on the moving rod...

[0039] The external telescopic protective cover 62 will protect the outside of the moving rod 421, thereby preventing impurities in the gas flowing inside the device from adhering to the threaded structure on the outer wall of the moving rod 421 and causing jamming during the later movement of the moving rod 421, thus making the later adjustment and movement of the moving rod 421 more flexible.

[0040] In the embodiments of this utility model, please refer to Figures 1 to 6. Guide rods 311 are fixedly installed on both sides inside the support frame 31. Symmetrically distributed lead screws 312 are rotatably installed between the two guide rods 311 inside the support frame 31. A motor driving the lead screws 312 is fixedly installed on the top of the support frame 31. A transition plate 32 is provided between the lead screw 312 and the guide rod 311 on the same side, with the inner wall of the transition plate 32 abutting and slidingly connected to the outer wall of the guide rod 311. The inner wall of the transition plate 32 is threadedly connected to the outer wall of the lead screw 312. The bottom of the transition plate 32 is fixedly connected to the top of the support column 33. A docking cylinder 331 is fixedly installed at the bottom end of the support column 33. A movably connected weight rod 21, which is attracted to each other by magnetic blocks, is inserted inside the docking cylinder 331. The bottom end of the weight rod 21 is connected to the exhaust weight 2. The top is fixedly connected, and the inner wall of the weight rod 21 and the docking cylinder 331 abuts against and slides against the outer wall of the insertion rod 411.

[0041] It should be noted that, due to the design of the lead screw 312, during use, when the working lead screw 312 rotates, the rotating lead screw 312, through the threaded structure between it and the adapter plate 32, drives the rotating plate and its bottom exhaust gas weight 2 and other components to move vertically on the outer wall of the guide rod 311. This allows for flexible adjustment of the position of the exhaust gas weight 2, enabling operators to flexibly adjust the sealing or opening of the device.

[0042] Started.

[0043] In the embodiments of this utility model, please refer to Figures 1 to 6. The side wall of the exhaust gas switch body 1 and the part opposite to the exhaust gas chuck 2 are provided with a side door that is rotatably connected by a hinge.

[0044] It should be noted that: by opening the side door, when disassembling and maintaining the exhaust gas weight 2, the staff can first open the side door and then carry out the disassembly operation of the exhaust gas weight 2. After the disassembly of the exhaust gas weight 2 is completed, the exhaust gas weight 2 can smoothly overflow from inside the exhaust gas switch body 1 through the side door.

[0045] The working principle of the coke oven exhaust gas switch provided by this utility model is as follows:

[0046] When using this device, if it is necessary to control the blocking state of the exhaust gas weight 2, the motor at the end of the lead screw 312 can be controlled by the terminal controller to work, thereby driving the lead screw 312 to rotate. At this time, the rotating lead screw 312 will drive the adapter plate 32 and its bottom support column 33 to move vertically through the threaded structure. The moving support column 33 will drive the exhaust gas weight 2 to move synchronously through the docking cylinder 331 and the weight 21. By adjusting the vertical movement of the exhaust gas weight, the blocking state of the exhaust gas weight 2 can be adjusted as needed.

[0047] When the exhaust gas roller 2 moves upward to release the blockage, it will move to a position relative to the cleaning strip 531 in the cleaning assembly 5. At this time, the terminal control can control the motor at the end of the drive rod 52 to drive the drive rod 52 to rotate. The rotation will drive the drive gear 521 on the outer wall to rotate. The rotating drive gear 521 will drive the rotating ring 53 and the cleaning strip 531 on its inner wall to rotate through the meshing with the linkage gear 54. Thus, the outer wall of the exhaust gas roller 2 can be scraped and cleaned by the rotation of the cleaning strip 531. Therefore, it can reduce the amount of adhering impurities on the outer wall of the exhaust gas roller 2 during use, which will affect the sealing effect in the later stage.

[0048] Furthermore, during subsequent use, when it is necessary to disassemble, repair, or replace the waste gas weight 2, the side door on the side wall of the waste gas switch body 1 can be opened, and then the rotating cylinder 42 can be rotated. At this time, the rotating cylinder 42 will drive the moving rods 421 on both sides to move in opposite directions through the threaded structure with opposite threads on both sides of the inner wall. The moving rods 421 that move in opposite directions can drive the insertion rod 411 to move synchronously through the end support plate 41, so that the insertion rod 411 can be moved out from the inside of the weight rod 21 and the docking cylinder 331, releasing the limiting fixation on both sides. After the limiting is released, the waste weight can be pulled down and then removed from the inside of the waste gas switch body 1 to complete the disassembly. The whole operation process is more convenient and faster.

[0049] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0050] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct...

[0051] If it is used indirectly in other related technical fields, it is similarly included within the scope of patent protection of this utility model.
