Description

Technical Field

[0001] The utility model relates to the technical field of hot-rolled coil production, and particularly relates to a dust removal device for hot-rolled coil production. Background Technique

[0002] Hot-rolled coil is a kind of steel plate produced by hot-rolling process, which is widely used in many fields such as construction, manufacturing and processing. At present, due to the relatively thick surface oxide layer of hot-rolled coil, a large number of iron oxide particles adhere to the surface of the plate after leveling and rolling, which is likely to cause quality problems such as indentations and pits on the surface of the plate. In order to solve the adhesion of iron oxide particles on the surface of hot-rolled coil, a dust removal device is usually set up. The iron oxide particles on the surface of hot-rolled coil are removed by cleaning the surface of hot-rolled coil with the dust removal device. Although most of the iron oxide particles on the surface of hot-rolled coil can be removed in this way, some iron oxide particles with stronger adhesion force will still adhere to the surface of hot-rolled coil, which will still make the surface of hot-rolled coil not smooth enough, resulting in scratches and indentations on the hot-rolled coil during the conveying process, thus reducing the production quality of hot-rolled coil.

[0003] Therefore, we propose a dust removal device for hot-rolled coil production to solve the above problems. Content of the Utility Model

[0025] Embodiment

[0026] As Figures 1-4 shown, a dust removal device for hot-rolled coil production proposed in an embodiment of the present utility model includes two limit plates 1. Between the two limit plates 1, a plurality of conveying rollers 2 are rotatably arranged. A dust removal component is arranged between the two limit plates 1, and a cleaning component is arranged on one side of the dust removal component. The cleaning component is used to scrape off impurities that are not easily removed on the surface of the hot-rolled coil;

[0027] The cleaning component includes a connecting frame 3 fixedly arranged between two limit plates 1. First servo motors 4 are fixedly arranged on the upper and lower side walls of the connecting frame 3. Two groups of slide bars 5 are fixedly arranged inside the connecting frame 3. Each group of slide bars 5 has a plurality of them. Sliders 6 are sleeved on each group of slide bars 5. On the opposite side walls of the two sliders 6, two cleaning scrapers 7 are fixedly arranged. The two cleaning scrapers 7 are arranged in a V shape;

[0028] On the upper and lower two side walls inside the connecting frame 3, a group of transmission members 8 are rotatably arranged. Each group of transmission members 8 has two of them. The two transmission members 8 are connected by a belt. A connecting rod 9 is fixedly arranged on the belt. A connecting plate 10 is fixedly arranged on the slider 6. A connecting groove 11 is formed in the connecting plate 10. The connecting rod 9 on the belt is inserted into the connecting groove 11 on the connecting plate 10. The output ends of the two first servo motors 4 are respectively docked with the two transmission members 8 inside the connecting frame 3.

[0029] Through the setting of the cleaning component, the iron oxide ash with strong adhesion can be scraped repeatedly, which can improve the cleaning effect of the iron oxide ash on the surface of the hot-rolled coil plate, making the surface of the hot-rolled coil plate smoother. Furthermore, it can reduce the phenomena of scratches and indentations on the hot-rolled coil plate during transportation due to the insufficient smoothness of the surface of the hot-rolled coil plate, and further effectively improve the production quality of the hot-rolled coil plate.

[0030] The dust removal component includes a rotary brush 12 rotatably arranged between two limit plates 1. There are two rotary brushes 12, and the two rotary brushes 12 are arranged vertically. A second servo motor 13 is fixedly arranged on one limit plate 1, and the output end of the second servo motor 13 is docked with one rotary brush 12. Transmission gears 14 are fixedly arranged at one end of each rotary brush 12, and the two transmission gears 14 mesh with each other. Through the setting of the transmission gears 14, the two rotary brushes 12 can rotate synchronously, and the setting of the second servo motor 13 provides kinetic energy for the rotation of the rotary brush 12.

[0031] The upper and lower sides of the rotary brush 12 are provided with protective shells 15. The protective shells 15 are fixedly connected to the two limit plates 1, and the rotary brush 12 and the cleaning component are located inside the protective shells 15. A negative pressure dust collector 16 is fixedly arranged on the protective shell 15, and the negative pressure dust collector 16 communicates with the protective shell 15. A pulse dust filter 17 is fixedly arranged on the negative pressure dust collector 16, and a connecting pipe 18 is fixedly arranged on the pulse dust filter 17. One end of the connecting pipe 18 away from the pulse dust filter 17 is connected to a dust collector 19. Through the setting of the protective shell 15, it plays a role in protecting the dust removal component and the cleaning component. The setting of the negative pressure dust collector 16 is used to suck the iron oxide ash on the surface of the hot-rolled coil plate. The setting of the pulse dust filter 17 can decompress and buffer the gas containing the absorbed iron oxide ash, and also filter the iron oxide ash passing through the pulse dust filter 17. The setting of the dust collector 19 filters the dust in the gas containing the absorbed iron oxide ash.

[0032] The working principle of this utility model:

[0033] When dust removal is required for the produced hot-rolled coil, start the first servo motor 4, the second servo motor 13, the negative pressure dust collector 16, the pulse dust filter 17, and the dust collector 19. The start of the first servo motor 4 drives the rotating member 8 connected thereto to rotate. The rotation of the rotating member 8 drives another rotating member 8 connected thereto by a belt to rotate. During the rotation of the belt, the connecting rod 9 is driven to move. The movement of the connecting rod 9 drives the connecting plate 10 to move. The movement of the connecting plate 10 drives the slider 6 to move. The movement of the slider 6 drives the cleaning scraper 7 to move repeatedly in the horizontal direction. The start of the second servo motor 13 drives the rotary brush 12 connected thereto to rotate. The rotation of the rotary brush 12 drives the transmission gear 14 connected thereto to rotate. The rotation of the transmission gear 14 drives another transmission gear 14 meshing therewith to rotate. The rotation of the two transmission gears 14 respectively drives the two rotary brushes 12 to rotate. At this time, place the hot-rolled coil on the conveying roller 2. One end of the hot-rolled coil passes through the two rotary brushes 12 and the two sliders 6 in sequence through the conveying roller 2. When the hot-rolled coil passes through the two rotary brushes 12, the two rotating rotary brushes 12 will loosen the iron oxide ash adhering to the upper and lower side walls of the hot-rolled coil. The loosened iron oxide ash will be sucked into the pulse dust filter 17 under the pull of the negative pressure dust collector 16. The pulse dust filter 17 preliminarily filters the iron oxide ash. The filtered iron oxide ash is transported to the dust collector 19 through the connecting pipe 18. The dust collector 19 filters the iron oxide ash again. The air that has been filtered multiple times is discharged into the air. When the hot-rolled coil passes through the two sliders 6, the cleaning scrapers 7 on the two sliders 6 will scrape off the iron oxide ash that has not been brushed off. The repeated movement in the horizontal direction will scrape off the iron oxide ash on the entire surface of the hot-rolled coil. The scraped iron oxide ash is processed through the above-mentioned negative pressure dust collector 16, pulse dust filter 17, connecting pipe 18, and dust collector 19.

[0034] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
