[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0024] See also Figure 1 - Figure 4 The utility model provides a technical solution: a steelmaking converter fume recovery device, comprising a shell 1, a cooling assembly 3 is installed on one side of the shell 1, and a filter plate 12 is fixedly installed inside the shell 1, and a cleaning mechanism 2 is installed on the other side of the shell 1;
[0025] The cleaning mechanism 2 includes an installation box 21 and a movable frame 23. The installation box 21 is internally rotatably connected to a rotating plate 27. One side of the rotating plate 27 is fixedly connected to the pushing plate 22. The bottom of the movable frame 23 is fixedly connected to a protrusion 231. The protrusion 231 abuts against the pushing plate 22. A limiting groove 232 is provided on the surface of the movable frame 23. The limiting groove 232 is internally slidably connected to a limiting rod 26. One end of the limiting rod 26 is fixedly connected to the inner wall of the installation box 21, and both end surfaces of the limiting rod 26 are fixedly connected to the limiting blocks 261. One end of the movable frame 23 is fixedly connected to the pushing rod 24. One end of the pushing rod 24 sequentially penetrates the installation box 21 and the shell 1. The other end of the pushing rod 24 is fixedly connected to a scraper 241. The scraper 241 is located on the surface of the filter plate 12.
[0026] The spray plate 11 can spray the flue gas to facilitate the removal of dust particles in the flue gas, and then the sludge will accumulate on the surface of the filter plate 12. At this time, the reduction motor 28 is used to drive the rotating plate 27 to rotate, so that when the rotating plate 27 drives the pushing plate 22 to rotate, an extrusion force is applied to the protrusion 231, so that the protrusion 231 will drive the moving frame 23 to move together. During this process, the moving frame 23 will use the pushing rod 24 to push the scraper 241 to slide on the surface of the filter plate 12, so that the scraper 241 can clean the sludge impurities on the surface of the filter plate 12.
[0027] During the cleaning process, the spring 25 begins to shrink because the movable frame 23 squeezes the spring 25. Due to the shape of the push plate 22, the projection 231 is reset as the push plate 22 rotates due to the presence of the spring 25.
[0028] Finally, during the continuous rotation of the rotating plate 27 and the pushing plate 22, the protrusion 231 and the moving frame 23 will drive the pushing rod 24 to do reciprocating motion, thereby controlling the scraper 241 to immediately reset after completing the work of scraping away impurities.
[0029] like Figure 3 As shown, the diameter of the limiting block 261 is larger than the longitudinal width of the limiting groove 232, so as to prevent the limiting rod 26 from being separated from the moving frame 23.
[0030] like Figure 3 As shown, the surface of the push rod 24 is sleeved with a spring 25, and the spring 25 is located on one side of the moving frame 23. It is convenient for the push rod 24 and the moving frame 23 to reset so as to form a reciprocating motion.
[0031] like Figure 2 As shown, a reduction motor 28 is installed on one side of the installation box 21, and the output end of the reduction motor 28 is fixedly connected to the rotating plate 27. The reduction motor 28 can be used to drive the rotating plate 27 to rotate, thereby entering the cleaning work.
[0032] like Figure 2 As shown, a spray plate 11 is fixedly installed on the top of the inner cavity of the shell 1, and a collection box 13 is fixedly installed on one side of the shell 1, and an exhaust pipe 14 is fixedly connected to one side of the shell 1. It is convenient to collect sludge.
[0033] like Figure 2 As shown, the cooling assembly 3 includes an air collecting pipe 33, one side of which is fixedly connected to the shell 1, and the bottom of the air collecting pipe 33 is connected to the shell 1, and the top of the air collecting pipe 33 is fixedly connected to the cooling pipe 32. It is convenient for the flue gas to enter the interior of the multiple cooling pipes 32 to improve the cooling effect.
[0034] like Figure 2 As shown, the top of the cooling pipe 32 is fixedly connected to the air inlet pipe 31, and the surface of the cooling pipe 32 is sleeved with a heat dissipation sleeve 321. This facilitates the cooling of the flue gas or the recovery of waste heat.
[0035] Usage method and working principle of this device: During the use of flue gas recovery, it first passes through the air intake pipe 31, and then is dispersed into multiple cooling pipes 32. At this time, not only can the flue gas be cooled, but also the excess heat in the flue gas can be processed in conjunction with the heat dissipation pipe, which can solve the problem of high flue gas temperature and recover the heat. After that, the flue gas will enter the shell 1 for dust removal.
[0036] The spray plate 11 can effectively remove various dust particles in the flue gas. Once these particles come into contact with water, they will be quickly removed to ensure the cleanliness of the flue gas.
[0037] As time goes by, sludge may gradually accumulate on the filter plate 12. To ensure the continuous and efficient operation of the system, the sludge needs to be cleaned regularly. At this time, the rotating plate 27 is started by the reduction motor 28 to start the rotation. As the rotating plate 27 rotates, the push plate 22 also starts to rotate synchronously.
[0038] The special structure of the push plate 22 and the protrusion 231 can exert force on the push rod 24 during the rotation process. This design enables the push rod 24 to drive the moving frame 23 to slide on the surface of the filter plate 12. The scraper 241 on the moving frame 23 can fit closely to the surface of the filter plate 12, ensuring that every sludge can be thoroughly cleaned.
[0039] During the cleaning process, the moving frame 23 interacts with the spring 25. When the moving frame 23 applies pressure to the spring 25, the spring 25 is compressed and accumulates energy. When the protrusion 231 gradually returns to its original position as the push plate 22 rotates, the spring 25 releases the stored energy to help the scraper 241 complete the return action.
[0040] The whole system realizes the reciprocating motion of the protrusion 231 and the moving frame 23 through the continuous rotation of the rotating plate 27 and the pushing plate 22. This reciprocating motion ensures that the scraper 241 can thoroughly clean the sludge impurities on the surface of the filter plate 12, and can quickly reset after each cleaning task is completed to prepare for the next cleaning work.
[0041] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
