[0026] The following is combined with Figure 1-5 This application is described in further detail.
[0027] The embodiment of the present application discloses a device for removing phosphorus from nickel iron before it is rolled out of the furnace.
[0028] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A dephosphorization device for ferronickel before rolling comprises a body 1 and a dephosphorization cover 2 fixedly mounted on the top of the body 1.
[0029] The top of the body 1 is open, and a plurality of conveying rollers 11 are rotatably mounted on the top of the body 1. The conveying rollers 11 are used to convey the target nickel-iron from left to right. A horizontal plate 12 is fixedly mounted horizontally inside the body 1, and a first scraper 121 is fixedly mounted on the top of the horizontal plate 12. The top of the first scraper 121 abuts against the bottom of the target nickel-iron, and the first scraper 121 is used to dephosphorize the bottom of the target nickel-iron.
[0030] The bottom, left and right ends of the dephosphorization cover 2 are all open.
[0031] A second scraper 211 is installed at the front end of the dephosphorization hood 2 through a first electric telescopic shaft 21. The first electric telescopic shaft 21 is placed horizontally. One end of the first electric telescopic shaft 21 is fixedly connected to the front end of the dephosphorization hood 2, and the other end is fixedly connected to the second scraper 211. The second scraper 211 abuts against the front end of the target nickel-iron. The second scraper 211 is used to dephosphorize the front end of the target nickel-iron.
[0032] A third scraper 221 is installed at the rear end of the dephosphorization hood 2 through the second electric telescopic shaft 22. The second electric telescopic shaft 22 is placed horizontally. One end of the second electric telescopic shaft 22 is fixedly connected to the rear end of the dephosphorization hood 2, and the other end is fixedly connected to the third scraper 221. The third scraper 221 abuts against the rear end of the target nickel-iron. The third scraper 221 is used to dephosphorize the rear end of the target nickel-iron.
[0033] A fourth scraper 231 is installed at the top of the interior of the dephosphorization hood 2 through the third electric telescopic shaft 23. The third electric telescopic shaft 23 is placed vertically. One end of the third electric telescopic shaft 23 is fixedly connected to the top of the interior of the dephosphorization hood 2, and the other end is fixedly connected to the fourth scraper 231. The fourth scraper 231 abuts against the top of the target nickel-iron. The fourth scraper 231 is used to dephosphorize the top of the target nickel-iron.
[0034] It should be noted that the first scraper 121, the second scraper 211, the third scraper 221 and the fourth scraper 231 are all staggered and will not interfere with each other.
[0035] Abrasive nozzles 25 are installed at the front and rear ends of the dephosphorization hood 2 through the installation assembly 24. The installation assembly 24 includes a fourth electric telescopic shaft 241 and a vertical plate 242. The fourth electric telescopic shaft 241 is placed horizontally, one end of the fourth electric telescopic shaft 241 is fixedly connected to the inner wall of the dephosphorization hood 2, and the other end is fixedly connected to the vertical plate 242. Three abrasive nozzles 25 are fixedly installed from top to bottom on the end of the vertical plate 242 facing the target nickel-iron. The three abrasive nozzles 25 are used to perform secondary dephosphorization on the upper end, lower end and front end (rear end) of the target nickel-iron. At the same time, the abrasive nozzles 25 also dephosphorize the left and right ends of the target nickel-iron.
[0036] It should be noted that the placement order of the first scraper 121, the second scraper 211, the third scraper 221, the fourth scraper 231 and the abrasive nozzle 25 is the first scraper 121, the second scraper 211, the third scraper 221, the fourth scraper 231 and the abrasive nozzle 25 according to the movement direction of the target nickel iron.
[0037] During the dephosphorization process, the iron oxide scale on the target nickel iron will fall into the fuselage 1. In order to facilitate the collection of the iron oxide scale, a collection box 3 and a guide plate 4 are provided inside the fuselage 1. The top of the collection box 3 is open, one end of the guide plate 4 is fixedly connected to the side wall of the fuselage 1, and the other end is fixedly connected to the top of the collection box 3. The guide plate 4 is provided with a push rod assembly 5 for pushing the iron oxide scale dropped from the nickel iron into the collection box 3. The push rod assembly 5 includes a fifth electric telescopic shaft 51 and a push plate 52. The fifth electric telescopic shaft 51 is fixedly mounted on the guide plate 4. The push plate 52 is fixedly mounted on the fifth electric telescopic shaft 51. The bottom end of the push plate 52 abuts against the top end of the guide plate 4. The fifth electric telescopic shaft 51 is used to slide the push plate 52 along the placement direction of the guide plate 4.
[0038] A screen 31 is fixedly installed horizontally in the collection box 3, and the meshes of the screen 31 are tapered. A crushing assembly 6 is provided in the collection box 3, and the crushing assembly 6 is used to crush the oxidized iron sheet that falls onto the screen 31, so as to facilitate the subsequent classification of the iron and impurities in the oxidized iron sheet. The left and right ends of the collecting box 3 are each provided with an identical slide groove 32. The crushing assembly 6 includes a pressing cylinder 62 and a sixth electric telescopic shaft 61 for driving the pressing cylinder 62 to rotate. The circumferential wall of the pressing cylinder 62 abuts against the top of the screen 31. Connecting rods 621 are fixedly installed at both ends of the pressing cylinder 62. The connecting rod 621 is located in the slide groove 32. The sixth electric telescopic shaft 61 is located in the slide groove 32. One end of the sixth electric telescopic shaft 61 is fixedly connected to the rear end groove wall of the slide groove 32, and the other end is fixedly installed with a connecting ring 611. The connecting ring 611 is replaced on the connecting rod 621 and is rotatably connected to the connecting rod 621. The sixth electric telescopic shaft 61 can drive the pressing cylinder 62 to repeatedly roll on the top of the screen 31, and roll the iron oxide skin on the top of the screen 31 into powder, and then the powdery iron oxide skin falls down.
[0039] It should be noted that the sixth electric telescopic shaft 61 applies a forward thrust to the pressing cylinder 62, and the screen 31 applies a backward friction force to the pressing cylinder 62, thereby causing the pressing cylinder 62 to rotate counterclockwise. Since the mesh holes of the screen 31 are conical and the iron oxide sheet is relatively brittle, when the pressing cylinder 62 encounters the iron oxide sheet, it can quickly crush the iron oxide sheet into powder, and will not cause the pressing cylinder 62 to slide due to the obstruction of the iron oxide sheet.
[0040] In order to classify the iron and impurities in the iron oxide scale, a plurality of drive motors 33 are horizontally fixedly installed on the outer wall of the collection box 3. The rotating shaft of the drive motor 33 passes through the outer wall of the collection box 3 and faces the inside of the collection box 3. A roller 34 is fixedly installed on the rotating shaft of the drive motor 33. A conveyor belt 35 is ringed on the plurality of rollers 34. The rotating shafts of the plurality of drive motors 33 all rotate counterclockwise, and then the conveyor belt 35 rotates counterclockwise. The conveyor belt 35 is located below the screen 31. A magnet 351 is fixedly installed on the outer wall of the conveyor belt 35. The magnet 351 is used to absorb iron powder. A baffle 36 is horizontally installed on the left end of the inner wall of the collection box 3. One end of the baffle 36 is fixedly connected to the collection box 3, and the other end is in contact with the outer wall of the conveyor belt 35. The baffle 36 is used to scrape off the iron powder adsorbed on the magnet 351. In order to distinguish iron powder from impurities, a partition plate 37 is vertically fixedly installed at the bottom of the collection box 3. The area on the left side of the partition plate 37 in the collection box 3 is used to collect iron powder, and the area on the right side is used to collect impurities.
[0041] In order to facilitate the transportation of iron powder and impurities, a first drawer 7 and a second drawer 8 are slidably mounted on the collection box 3. The first drawer 7 is used to collect and transport iron powder, and the second drawer 8 is used to collect and transport impurities. It should be noted that a first through hole 38 is provided at the front end of the collection box 3, and a second through hole 13 identical to the first through hole 38 is provided at the front end of the body 1. The first through hole 38 and the second through hole 13 are used for the first drawer 7 and the second drawer 8 to slide in and out of the collection box 3.
[0042] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
