Technical Field
[0001] This utility model belongs to the field of waste gas treatment technology, specifically a waste gas treatment device for industrial blast furnaces. Background Technology
[0002] Industrial production generates a large amount of waste gas. If it is discharged directly without treatment, it will cause serious harm to the environment and human health. Bag dust collectors are equipment used for the treatment of industrial blast furnace waste gas. They mainly use filter bags to filter the dust contained in the industrial blast furnace waste gas. The pulse-jet cleaning mechanism cleans the dust on the filter bags at regular intervals, and the dust is collected and discharged by the ash hopper.
[0003] Existing industrial blast furnace exhaust gas treatment equipment still has the following shortcomings: Existing industrial blast furnace exhaust gas treatment equipment is inconvenient to clean. After long-term operation, the vibration and other factors of the existing bag filter dust collector will cause dust to gradually adhere to the inner wall of the ash hopper. This part of the dust is difficult to clean, which will reduce the ash discharge efficiency of the ash hopper and may also block the channel, affecting the overall operation of the exhaust gas treatment equipment. Utility Model Content

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0020] like Figures 1-4 As shown, this utility model provides a technical solution:
[0021] It includes a clean air box 1, an exhaust port 2 connected to one side of the clean air box 1, an air inlet 3 connected to the side of the clean air box 1 away from the exhaust port 2, a pair of support feet 4 on both sides of the clean air box 1, an opening and closing frame 5 fixedly connected to the bottom of the clean air box 1, an opening and closing component on the opening and closing frame 5, an ash hopper 6 fixedly connected to the bottom of the opening and closing frame 5, and a rotating component on the ash hopper 6.
[0022] Specifically, the blast furnace exhaust gas enters the clean air box 1 through the air inlet 3. The clean air box 1 is equipped with a bag filter dust removal mechanism, which can filter the dust in the exhaust gas. The filtered exhaust gas is discharged from the clean air box 1 through the exhaust outlet 2. The dust on the filter bag is discharged through the ash hopper 6 under the action of the jet cleaning mechanism.
[0023] A pair of connecting blocks 7 are fixedly connected to both sides of the ash hopper 6. A connecting shaft 8 is rotatably connected to each connecting block 7. A rotating plate 9 is fixedly connected to one end of the connecting shaft 8. A base 10 is fixedly connected to one side of the ash hopper 6.
[0024] Specifically, the rotating plates 9 on both sides of the ash hopper 6 can rotate together with the connecting shaft 8 on the connecting block 7. After the rotating plates 9 are rotated and opened, the cleaning space is greatly expanded, and the cleaning personnel can more easily use tools to clean the inside of the ash hopper 6 in all directions, improve the cleaning efficiency, ensure the cleanliness of the ash hopper 6, and avoid affecting the ash unloading effect and equipment operation due to excessive ash accumulation.
[0025] The rotating assembly includes a hydraulic cylinder 11, which is fixedly connected to the base 10. A lifting block 12 is fixedly connected to the output end of the hydraulic cylinder 11. Two pairs of connecting blocks 13 are fixedly connected to one side of the ash hopper 6. A sliding rod 14 is fixedly connected between each pair of connecting blocks 13. The sliding rod 14 is slidably connected to the lifting block 12. A pair of through slots 15 are provided on the lifting block 12.
[0026] Specifically, the hydraulic cylinder 11 is activated, and the output end of the hydraulic cylinder 11 drives the lifting block 12 to slide and rise on the slide rod 14. The slide rod 14 makes the lifting block 12 more stable when it moves.
[0027] A connecting shaft 16 is fixedly connected to one side of the rotating plate 9, and the connecting shaft 16 is adapted to the through groove 15;
[0028] Specifically, the connecting shaft 16 moves from one end of the through groove 15 to the other end, and the rotating plate 9 rotates around the connecting shaft 8 through the lever principle;
[0029] The opening and closing assembly includes a housing 17, which is fixedly connected to one side of the opening and closing frame 5. A servo motor 18 is fixedly connected to one side of the housing 17. The output end of the servo motor 18 passes through the housing 17 and is rotatably connected to it. A bidirectional threaded rod 19 is coaxially fixedly connected to the output end of the servo motor 18. A pair of nuts 20 are threadedly connected to the bidirectional threaded rod 19. A slider 21 is fixedly connected to the side of each nut 20 near the opening and closing frame 5. The slider 21 is slidably connected to the opening and closing frame 5. An opening and closing plate 22 is fixedly connected to the side of the slider 21 away from the nut 20. The opening and closing plate 22 is slidably connected to the opening and closing frame 5.
[0030] Specifically, the servo motor 18 is started, and the output end of the servo motor 18 drives the bidirectional threaded rod 19 to rotate, causing a pair of nuts 20 to move closer to each other. Through the slider 21, the opening and closing plate 22 slides and moves closer to each other on the opening and closing frame 5 until the connection channel between the clean air box 1 and the ash hopper 6 is closed, preventing dust from accidentally entering the clean air box 6 during the cleaning process, ensuring the cleanliness of the clean air box 6, and also avoiding interference with the normal filtration function of the clean air box 6 of the bag dust collector during the cleaning work, thus ensuring the stable operation of the system.
[0031] A dustproof plate 23 is fixedly connected to one side of the hinge plate 22;
[0032] Specifically, the dustproof plate 23 can prevent dust from entering the two sides of the opening and closing frame 5 where the opening and closing plate 22 is located.
[0033] The working principle of this utility model is as follows:
[0034] Blast furnace exhaust gas enters clean air box 1 through air inlet 3. Clean air box 1 is equipped with a bag filter dust removal mechanism, which can filter the dust in the exhaust gas. The filtered exhaust gas is discharged from clean air box 1 through exhaust outlet 2. The dust on the filter bag is discharged through ash hopper 6 under the action of the jet cleaning mechanism.
[0035] When it is necessary to clean the inner wall of the ash hopper 6, the servo motor 18 is started first. The output end of the servo motor 18 drives the bidirectional threaded rod 19 to rotate, causing a pair of nuts 20 to move closer to each other. Through the slider 21, the opening and closing plate 22 slides on the opening and closing frame 5 and moves closer to each other until the connection channel between the clean air box 1 and the ash hopper 6 is closed. This can prevent dust from accidentally entering the clean air box 6 during the cleaning process, ensuring the cleanliness of the clean air box 6. It can also avoid the cleaning work from interfering with the normal filtration function of the clean air box 6 of the bag dust collector, ensuring the stable operation of the system.
[0036] Restarting the hydraulic cylinder 11 causes the output end of the hydraulic cylinder 11 to drive the lifting block 12 to slide and rise on the slide rod 14, so that the connecting shaft 16 on the rotating plate 9 moves from one end of the through groove 15 to the other end. Through the lever principle, the rotating plate 9 and the connecting shaft 8 can rotate and open together on the connecting block 7, which greatly expands the cleaning space. Cleaning personnel can more easily use tools such as scrapers and water guns to clean the inside of the ash hopper 6 in all directions, improve cleaning efficiency, ensure the cleanliness of the ash hopper 6, and avoid affecting the ash unloading effect and equipment operation due to excessive ash accumulation.
[0037] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
