Description

Technical Field

[0001] This utility model relates to the field of coking furnace technology, specifically a coal coking furnace. Background Technology

[0002] A coal coking furnace is an industrial equipment used for coal coking. Coal coking refers to the process in which coal undergoes pyrolysis under conditions of isolation from air and within a certain temperature range to produce products such as coke, coal tar, crude benzene, and coal gas. The coking furnace provides a suitable temperature environment and reaction space for this process.

[0003] Existing coking furnaces generate a large amount of exhaust gas and dust during operation. During the gas emission process, adsorption filtration is often used to treat the exhaust gas. However, in actual use, activated carbon is used for adsorption filtration. When the activated carbon becomes saturated, replacement is troublesome. Because the activated carbon is installed inside the purification device, it is fixed with bolts to ensure the device's seal, making replacement difficult and inefficient, thus reducing its practicality. Utility Model Content

[0035] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.

[0036] like Figures 1 to 8As shown in the figure, the coal coking furnace provided in this embodiment of the present invention includes a coking furnace body 1. An exhaust pipe 11 is fixedly connected to the upper end face of the coking furnace body 1. A purification box 12 is fixedly connected to the end of the exhaust pipe 11 away from the coking furnace body 1. A filter plate 13 is provided in the purification box 12. An installation groove 14 and a movable groove 15 are respectively opened on the upper end face of the purification box 12. A sealing plate 16 is movably connected in the installation groove 14. An installation frame 17 is movably connected to the lower end face of the sealing plate 16. Multiple evenly distributed slots 18 are opened on the inner walls of both sides of the installation frame 17. Multiple activated carbon honeycomb plates 19 are movably connected to the installation frame 17 and are located in the slots 18. A fixing block 20 is fixedly connected to the upper end face of the sealing plate 16. A slot 2 is opened on the fixing block 20. 1. A plug block 22 is movably connected within the slot 21. A connecting block 23 is fixedly connected to one side of the plug block 22. A pull rod 24 is fixedly connected to the side of the connecting block 23 away from the plug block 22. A positioning block 25 is slidably connected to the outer wall of the pull rod 24. The positioning block 25 is fixedly connected to the sealing plate 16. A spring 26 is sleeved on the outer surface of the pull rod 24. The two ends of the spring 26 are fixedly connected to the positioning block 25 and the connecting block 23, respectively. The three activated carbon honeycomb plates 19 are aligned with the corresponding slots 18 on the mounting frame 17 to ensure the stability of the activated carbon honeycomb plates 19 and facilitate the adsorption and purification of exhaust gas. The alignment of the plug block 22 with the slot 21 can fix the sealing plate 16. Pulling the pull rod 24 can move the connecting block 23 and the plug block 22. This allows the connecting block 23 to compress the spring 26, enabling rapid unlocking and facilitating the disassembly of the sealing plate 16. This also facilitates the quick replacement of the saturated activated carbon honeycomb plate 19. Two symmetrical docking slots 31 are provided on one side of the mounting frame 17. A docking block 32 is movably connected within each slot 31. A retaining block 33 is fixedly connected to one side of each docking block 32 and is fixedly connected to the sealing plate 16. The two docking blocks 32 dock with their respective docking slots 31, connecting the sealing plate 16 to the mounting block and ensuring a stable connection. Fixing rods 41 are fixedly connected to the inner walls of both sides of the purification box 12. Connecting slots 42 are provided on opposite sides of each fixing rod 41. Movable connections are made within the connecting slots 42. A connecting rod 43 is connected to the mounting frame 17. The two connecting rods 43 ensure a stable connection between the mounting frame 17 and the two fixed rods 41, guaranteeing sufficient stability during use. A guide groove 51 is provided on the upper surface of the purification box 12. A guide block 52 is slidably connected within the guide groove 51 and is fixedly connected to the connecting block 23. The guide groove 51 and guide block 52 guide the connecting block 23, ensuring sufficient stability during movement. An elastic hose 61 is fitted over the outer surface of the spring 26. Both ends of the elastic hose 61 are fixedly connected to the connecting block 23 and the positioning block 25, respectively. The elastic hose 61 protects the spring 26.To prevent the spring 26 from corroding, a sealing rod 71 is movably connected within the movable groove 15. The sealing rod 71 is fixedly connected to the filter plate 13. A stabilizing block 72 is fixedly connected to the upper surface of the sealing plate 16. The stabilizing block 72 is fixed to the purification chamber 12 by two symmetrical fixing bolts 73. The sealing rod 71 can seal the movable groove 15. Combined with the two stabilizing blocks 72 and their corresponding fixing bolts 73, the sealing rod 71 and the filter plate 13 can be fixed. An exhaust pipe 81 is fixedly connected to the side of the purification chamber 12 away from the exhaust pipe 11. The exhaust pipe 81 is used to discharge the purified exhaust gas.

[0037] The working principle and usage process of this utility model are as follows: During operation, the exhaust gas from the coking furnace is first transported to the purification box 12 through the exhaust pipe 11. After being filtered by the filter plate 13, the impurities in the exhaust gas are filtered out. In conjunction with the three activated carbon honeycomb plates 19, the exhaust gas is adsorbed and filtered. The purified exhaust gas is effectively discharged through the discharge pipe 81. When the activated carbon honeycomb plate 19 is saturated, the moving block 22 is moved to one side by the pull rod 24, causing the block 22 to disengage from the slot 21. The sealing plate 16 and the mounting frame 17 are then pulled out of the purification box 12, causing the sealing plate 16 to slide to one side, causing the connecting block 32 to disengage from the connecting groove 31, exposing the activated carbon honeycomb plate 19. The activated carbon honeycomb plate 19 is then pulled out, and the saturated activated carbon honeycomb plate 19 is replaced. It is then reinstalled, thus realizing the exhaust gas treatment process during the entire operation of the coking furnace.
