[0059] The following is based on Figures 1-18 The present invention provides an embodiment of a device for removing adhered matter from the inner wall of a ladle for producing silicon-manganese alloy.

[0060] See also Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an apparatus for removing adhesions on the inner wall of a molten iron ladle for silicon-manganese alloy production, comprising a molten iron ladle transfer vehicle 17 and a ground rail 1. The molten iron ladle transfer vehicle 17 can move on the ground rail 1, with one end of the ground rail 1 close to the molten iron pool and the other end close to the forming mold. The molten iron ladle transfer vehicle 17 moves on the ground rail 1, which can facilitate the transfer of the molten iron ladle 2 to the molten iron pool area for loading and the mold area for unloading.

[0061] Combine Figure 1-Figure 4 As shown, specifically, the prior art has X-axis rails 18 on both sides of the upper surface of the ladle transfer vehicle 17, a slidable gantry is provided on the X-axis rails 18, and a ladle support frame 10 is also installed on the gantry, and a Z-axis rail 11 is provided on the gantry. The gantry and the Z-axis rail 11 form a whole, and the gantry can move horizontally on the X-axis, and the ladle support frame 10 can slide along the Z-axis rail 11, thereby realizing the movement of the ladle 2 in the X-axis and Z-axis directions on the upper surface of the ladle transfer vehicle 17, making it convenient for the ladle to approach the mold and reach the height of the pouring.

[0062] It is worth noting that in the present invention, whether it is X-axis movement, the drive in the prior art can adopt linear guide rails, screw drive, belt drive or rack and pinion drive, which will not be described in detail here. Z-axis movement can adopt cylinders or hydraulic cylinders.

[0063] In addition, a turning motor 101 capable of controlling the turning of the ladle 2 is provided on the ladle support frame 10, so as to facilitate the ladle 2 to pour the molten iron into the mold.

[0064] The above are all common technical solutions in the prior art, and the present invention aims to: after the molten iron ladle 2 is poured into the mold, the wet material in the molten iron ladle 2 is scraped off during the process of returning to the molten iron pool area, that is, a cleaning is performed after each pouring to avoid waste accumulation.

[0065] Specifically, the device for removing adhesions on the inner wall of a ladle for silicon-manganese alloy production in the embodiment of the present invention is provided with a main shaft 3 and a transmission assembly. The main shaft 3 is rotatably mounted on the middle part of the upper surface of the ladle transfer vehicle 17. A scraping device is installed on the upper end of the main shaft 3. The transmission assembly is separately provided on the ladle transfer vehicle 17 and the ladle support frame 10. When the ladle support frame 10 descends, the main shaft 3 can be driven to rotate by the transmission assembly.

[0066] Specifically, after pouring the molten iron, the ladle 2 moves along the X-axis on the ladle transfer vehicle 17 so that the ladle 2 is aligned with the scraper device and is turned over to have the opening facing downward. The ladle 2 aligned with the scraper device descends to the scraper device along with the ladle support frame 10, and the scraper device is controlled by the transmission component to scrape the wet material from the inner wall of the ladle 2 in a rotating posture.

[0067] That is, cleaning is performed after each pouring to avoid waste accumulation.

[0068] like Figure 1 、 Figure 4-Figure 6 As shown, specifically, the above-mentioned transmission assembly includes a rack plate 41, an outer cover 42 and a bevel gear 48. The rack plate 41 is fixed to the side of the ladle support frame 10 away from the ladle 2, and the outer cover 42 is fixed to the middle of the end of the upper surface of the ladle transfer vehicle 17 away from the loading and unloading of the ladle 2, and a power gear 43 adapted to the rack plate 41 is rotatably arranged in the outer cover 42. When the ladle support frame 10 descends and passes through the power gear 43, it can push the power gear 43 to rotate.

[0069] Bevel gear 2 48 is fixed to the lower end of the main shaft 3, and bevel gear 1 47 is engaged with one side of bevel gear 2 48. Bevel gear 1 47 is coaxial with turbine 1 46, and worm 1 49 is engaged with the top of turbine 1 46. A belt transmission structure is provided between worm 1 49 and power gear 43. When the power gear 43 rotates, the worm 1 49 can be driven to rotate through the belt transmission structure. When the worm 1 49 rotates, the turbine 1 46 can be controlled to rotate, and then the main shaft 3 is driven to rotate through bevel gear 1 47 and bevel gear 2 48.

[0070] Preferably, the belt transmission structure mentioned above is preferably a two-set belt structure, referring to Figure 6 , one of which is an acceleration belt structure, refer to Figure 6 As shown, the belt transmission structure 1 44 is a constant speed belt, and the belt transmission structure 2 45 is an acceleration belt, thereby avoiding the situation where the scraping device does not scrape the material thoroughly due to the slow rotation speed of the main shaft 3.

[0071] Combine Figure 7-Figure 9As shown, the upper end of the main shaft 3 is provided with an assembly head 31, and the scraping device is installed on the assembly head 31. The scraping device includes a scraper 6, and the scraper 6 is assembled on the periphery of the assembly head 31 through a knife shaft 61. The scraper 6 is provided with at least three groups, and 10 groups of scrapers 6 are shown in the figure. When the ladle 2 moves downward, the scraper 6 is Figure 7 In the state shown, the main shaft 3 is rotated as the center to scrape off the wet material in the ladle 2.

[0072] In order to make the scraped wet waste fall off the inner wall of the ladle 2 completely, an adjustment mechanism is provided. The adjustment mechanism is provided in the assembly head 31. When the ladle 2 moves downward, the three groups of scrapers 6 are adjusted to be inclined and to scrape the inner wall of the ladle 2 in a revolving state (such as Figure 7 The state shown), and is used to adjust the three groups of scrapers 6 to form a horizontal shape when the ladle 2 rises and gradually separates from the scraper 6 to form a circular ring structure, and scrape the slag on the inner wall of the ladle 2 in a circular posture (such as Figure 10 The wet scraps scraped off can be ensured to fall downwards and away from the inner wall of the ladle 2.

[0073] When the ladle 2 moves upward, the annular scraper 6 scrapes the inner wall of the ladle 2 to ensure that all waste materials are separated downward from the ladle 2 to avoid any residue.

[0074] Combine Figure 8 、 Figure 9 、 Figure 11 and Figure 12 As shown, the adjustment mechanism includes a hollow worm gear 2 71, which is rotatably mounted at the center of the assembly head 31, and a turbine 2 73 is engaged with the outer periphery of the hollow worm gear 2 71 in the area opposite to the main shaft 3. The number of turbines 2 73 is the same as the number of scrapers 6, and a gear 1 74 coaxial with the turbine 2 73 is provided on one side of the end of the turbine 2 73, and a gear 2 75 is engaged below the gear 1 74, and a bevel gear 4 77 coaxial with the gear 2 75 is provided on one side of the gear 2 75, and a bevel gear 3 76 is engaged with one side of the bevel gear 4 77, and a bevel gear 3 76 is fixed to the middle of the bevel gear 3 76, and the other end of the bevel gear 3 76 is fixed to the knife shaft 61.

[0075] In this embodiment, when the hollow worm 2 71 rotates, it can directly drive the turbine 2 73 to rotate, and the turbine 2 73 can drive the gear 1 74 to rotate. When the gear 1 74 rotates, the bevel gear 4 77 is driven to rotate through the gear 2 75, and then the rotation of the bevel gear 3 76 can be realized. When the bevel gear 3 76 rotates, the scraper 6 can be driven to rotate to the required angle through the knife shaft 61.

[0076] The reason why the worm gear structure is adopted here is to achieve self-locking, so as to prevent the scraper 6 from rotating and moving by itself due to the friction of the inner wall of the ladle 2.

[0077] Preferably, it also includes a bearing seat 72, which is fixed in the assembly head 31 and is used to carry the adjustment mechanism. Figure 11 It can be better understood that turbine 2 73 , gear 1 74 , gear 2 75 and bevel gear 4 77 are all assembled on the bearing seat 72 ; of course, the bearing seat 72 here can also be a structure integrated with the assembly head 31 .

[0078] like Figure 8 and Figure 12 As shown, when the ladle 2 moves downward toward the scraper 6, the scraper 6 is Figure 7 In the state shown, the inner wall of the ladle 2 is cleaned. When the ladle 2 drops to the lowest height, the scraping is completed. At this time, the hollow worm 2 71 needs to be rotated to control the rotation of the turbine 2 73. In order to achieve the purpose of automatic rotation of the hollow worm 2 71 when the ladle 2 is about to drop to the lowest height, a force-bearing rod 8 is inserted into the interior of the hollow worm 2 71. The upper end of the force-bearing rod 8 protrudes from the upper surface of the assembly head 31, and a spiral track 711 is provided on the inner wall of the hollow worm 2 71. The outer surface of the force-bearing rod 8 is provided with a slider 84 adapted to the spiral track 711.

[0079] When the ladle 2 is about to drop to the lowest height, the contact plate 16 is pushed downward by the bottom pressure of the ladle 2. When it moves downward, it can push the spiral track 711 through the slider 84, so that the hollow worm 71 produces a circumferential motion, and then the knife shaft 61 rotates. When the knife shaft 61 rotates, it can achieve Figure 7-10 status changes.

[0080] In fact, in order to achieve the next subsequent cleaning, the scraper 6 can still be in Figure 7 The inclined state shown in the figure is used for scraping, and the scraper 6 forms a Figure 10 After the state, when the ladle 2 moves upward, the scraper 6 can maintain Figure 10 The inner wall of the ladle 2 is scraped in the state of scraping, and the following scheme is designed:

[0081] like Figure 12 and Figure 14 As shown, a track column 81 is fixedly provided at the lower end of the force-bearing rod 8, and a spring 1 85 is fixedly provided at the lower end of the track column 81. When the force-bearing rod 8 is subjected to pressure from the bottom wall of the molten iron ladle 2, it can also push the track column 81 to move downward. The spring 1 85 is in a compressed state at this time. A track groove 82 is provided on the periphery of the track column 81, and a locking hole 83 is provided at the upper end of the track groove 82. A locking structure 9 is also provided on the main shaft 3. The locking structure 9 includes a locking rod 93. The locking rod 93 is radially inserted into the locking rod 93 from the outside of the main shaft 3 and is opposite to the track groove 82. A spring 2 94 is provided on the periphery of the locking rod 93.

[0082] When the track column 81 moves downward with the force rod 8, the locking rod 93 slides relatively in the track groove 82. At this time, the spring 2 94 is in a compressed state. The track column 81 moves downward with the force rod 8, and when the locking rod 93 aligns with the locking hole 83, the spring 2 94 releases its elasticity, and the locking rod 93 enters the locking hole 83 to lock the height of the force rod 8 and the track column 81 after moving downward. At this time, the height of the track column 81 no longer changes, and the hollow worm 2 71 no longer rotates, thereby locking the annular structure of the scraper 6. At this time, when the ladle 2 moves upward again, the scraper 6 can be realized. Figure 10 The purpose of scraping the waste directly downwards.

[0083] Reference Figure 1 、 Figure 3 and Figure 12 As shown, in order to realize that after the ladle 2 is separated from the scraper 6 upward, the scraper 6 can also be moved from Figure 10 The status is restored to Figure 7 The state shown is to facilitate the next cleaning operation. The locking structure 9 here also includes an outer ring 91. The outer ring 91 is sleeved on the periphery of the main shaft 3 and is located below the locking rod 93. A push rod 92 is hinged between the end of the locking rod 93 away from the push rod 92 and the outer ring 91; an L-shaped hanger 15 is provided below the ladle support frame 10, and a wedge block 5 is installed on the L-shaped hanger 15 in the area opposite to the outer ring 91.

[0084] In this embodiment, referring to Figure 1 After the cleaning is completed, the entire gantry and the Z-axis rail 11 move to the right along the X-axis rail 18. At this time, the wedge block 5 can push the outer ring 91 to move the outer ring 91 upward. When the outer ring 91 moves upward, it can push the push rod 92 upward, so that the push rod 92 can pull the locking rod 93 outward. At this time, the locking rod 93 disengages from the locking hole 83. At this time, the elastic force of the spring 1 85 is released, thereby pushing the track column 81 and the force rod 8 to move upward, and through the action of the slider 84 and the spiral track 711, the hollow worm 2 71 rotates in the opposite direction, so that the turbine 2 73 can rotate in the opposite direction, and the knife shaft 61 can rotate in the opposite direction, thereby realizing the scraper 6 from Figure 10 The status shown is restored to Figure 7 The status shown is waiting for the next scraping operation.

[0085] In order to ensure that the bottom of the ladle 2 can also be cleaned, Figure 7 As shown, side plates 311 are provided on both sides of the assembly head 31, and a guide rod 14 is inserted into the side plate 311 in the vertical direction. A spring three 13 is provided on the outer periphery of the guide rod 14, and the lower end of the spring three 13 is fixed in the side plate 311. A top knife 12 is installed on the upper end of the guide rod 14. The top knife 12 is at the same height as the contact plate 16. The top knife 12 can contact the bottom of the ladle 2 and can withstand a certain pressure from the bottom of the ladle 2, thereby cleaning the bottom of the barrel.

[0086] Preferably, a slag pan 19 is installed on the upper surface of the ladle transfer car 17 in an area opposite to the main shaft 3. The slag pan 19 is used to receive the scrap scraped from the ladle 2 so that the falling wet waste can fall onto the slag pan 19.

[0087] When in use (working), the ladle transfer car 17 moves on the ground rail 1 to the area close to the molten iron pool and loads the material ( Figure 15 The ladle 2 after loading is moved to the position of the mold along the ladle transfer vehicle 17, and the ladle support frame 10 is controlled to move upward along the Z-axis rail 11 until it reaches the required pouring height. At this time, the flip motor 101 is controlled to work to flip the ladle 2 to the required angle for pouring ( Figure 16 As shown), after the pouring is completed, the entire ladle transfer car 17 needs to be moved on the ground rail 1 to the molten iron pool to reload. In this process, the Z-axis rail 11 is driven to move along the X-axis rail 18 to Figure 2 In the state shown, the flip motor 101 is controlled to flip the ladle 2 to open downward, and the ladle support frame 10 is controlled to descend. In this process, the transmission assembly can drive the main shaft 3 to rotate, so that the scraper 6 is Figure 7 In the state shown, the inner wall of the ladle 2 is cleaned. When the contact plate 16 is subjected to the pressure from the bottom of the ladle 2, the contact plate 16 can press the force rod 8 downward, so that the force rod 8 is Figure 17 The state shown is formed Figure 18 In the state shown, the spring 2 94 is compressed, the locking rod 93 enters the locking hole 83, and the height of the force rod 8 is locked. When the force rod 8 moves downward, the hollow worm 2 71 can be rotated by the action of the slider 84 and the spiral track 711, thereby realizing the purpose of the self-rotation of the knife shaft 61, so that it forms Figure 10 In the state shown, the ladle 2 starts to move upward along the Z axis, and the scraper 6 moves upward along the Z axis. Figure 10 The state shown is to scrape off all the scraps and push them downwards, ensuring that the scraps can be separated from the inner wall of the ladle 2.
