Description

Technical Field

[0001] The present invention relates to the field of metal smelting, and particularly to an automatic slag skimming device for metal smelting. Background Art

[0002] During the process of smelting metal, the metal raw materials contain a large amount of impurities and harmful substances, such as oxides, sulfides, etc. These substances react with fluxes, reducing agents and other substances at high temperatures to form a mixture of gases and liquids, that is, slag. In addition, elements such as silicon and manganese in the metal will also undergo oxidation reactions with oxygen to form corresponding oxides, and these oxides are also part of the slag. The impurities and harmful substances in these slags will affect the quality of the metal. Therefore, it is necessary to skim the slag from the smelting furnace to ensure the purity and quality of the metal.

[0003] For example, the patent with the authorized publication number of CN216421057U and the publication date of May 3, 2022 discloses a slag skimmer for the front of a high-silicon silicomanganese submerged arc furnace, including a support platform in front of the furnace. A support track is fixed on the top of the support platform through a base. A movable slag skimming trolley is arranged in the support track. A slag skimming boom is hinged on the top of the slag skimming trolley. A slag skimming shovel for skimming slag from the ladle is fixed at the front end of the slag skimming boom. The tail of the slag skimming boom is hinged and fixed to a hydraulic cylinder hinged and fixed on the slag skimming trolley. However, when the above scheme is actually used, there are still certain deficiencies. For example, during the use process, the slag skimming trolley drives the slag skimming boom to extend the slag skimming shovel into the liquid surface to pick out the floating slag, and the whole process needs to be repeated many times, resulting in low work efficiency; since the molten iron in the ladle is in a high-temperature state and has a certain fluidity, the slag in the molten iron will be in full contact with the slag skimming shovel, and the stability of the slag skimming shovel is relatively low. Some components in the iron slag will rapidly cool and solidify on the surface of the slag skimming shovel and thus adhere to it. Moreover, the above device lacks a cleaning design for the slag skimming shovel, resulting in the slag skimming shovel being prone to accumulating iron slag during the use process, increasing the resistance of the slag skimming shovel and making the slag skimming process more difficult, further reducing the slag skimming efficiency.

[0004] Based on the above situation, the present invention proposes an automatic slag skimming device for metal smelting. Summary of the Invention

This technology is existing technology and will not be elaborated on here. The front part of the first multi-section electric push rod is fixedly hinged with the cross bar of the inverted L-shaped fixing member. The first multi-section electric push rod is composed of four sections of cylinders, and the arrangement order of these sections from front to back is gradually tapered. The telescopic end of the rear side of the first multi-section electric push rod 13 is fixedly connected with a fixed block, and racks are provided on both sides of the fixed block. A pusher 141 is fixedly connected to the top front side of the double-sided rack 14, and a positioning assembly is provided on the double-sided rack 14. The upper side of the inverted L-shaped fixing member 12 is slidably connected to a moving member 17 symmetrically distributed on the left and right. The bottoms of the two moving members 17 are rotatably connected to a rotating member 19. The upper sides of the two rotating members 19 are fixedly connected to a first gear 18. The tops of the two rotating members 19 are slidably connected to symmetrically distributed card blocks 192. The symmetrically distributed card blocks 192 and the adjacent rotating members 19 are connected with positioning springs 191. The symmetrically distributed The locking springs 191 are all wound around the adjacent rotating parts 19, and the rotating parts 19 and the moving parts 17 are engaged with each other through the adjacent blocking blocks 192. The lower sides of the two rotating parts 19 are fixed with elastic telescopic parts 110, and each elastic telescopic part 110 is composed of four sections, and the arrangement order of these sections from front to back is gradually tapering. This is the prior art and will not be elaborated on. A pressure spring 111 is connected between the telescopic end and the fixed part of each elastic telescopic part 110, and the double-sided rack 14 is meshed with the two first gears 18.

[0032] like Figure 4 As shown, the locking assembly includes a buckle 15, which is slidably connected to the top rear side of the double-sided rack 14, and a storage spring 16 is connected between the buckle 15 and the double-sided rack 14, and the storage spring 16 is wound around the buckle 15. Both moving parts 17 are squeezed and fitted with the buckle 15, that is, when the first multi-section electric push rod 13 moves backward, the moving part 17 will be clamped by the pushing part 141 and the buckle 15 from the front and back sides.

[0033] like Figures 6 - 8As shown, it also includes a scraping mechanism for cleaning the scraping slag attached to the elastic telescopic member 110, the scraping mechanism is arranged on the inverted L-shaped fixing member 12, and the scraping mechanism includes a second multi-section electric push rod 2, the second multi-section electric push rod 2 is installed on the upper rear part of the inverted L-shaped fixing member 12, the telescopic end of the inverted L-shaped fixing member 12 is fixedly connected to a first wedge block 21, and the first wedge block 21 is provided with an unlocking component for releasing the lock between the buckle 15 and the two moving members 17, the lower rear parts of the two rotating members 19 are fixedly connected to the first guide rail 27, and the two first The guide rails 27 are all slidably connected with scraping members 25, and the tops of the two scraping members 25 are both provided with inclined surfaces. The scraping members 25 slide on the adjacent elastic telescopic members 110, and the rear sides of the two first guide rails 27 are fixedly connected with telescopic shells 26, and the telescopic parts of the telescopic shells 26 are fixedly connected to the adjacent scraping members 25. Compression springs 28 are connected between the scraping members 25 and the fixed parts of the adjacent telescopic shells 26, and the two compression springs 28 are both wound around the adjacent first guide rails 27, and the first wedge block 21 is squeezed and fitted with the inclined surfaces of the two scraping members 25.

[0034] like Figure 7 As shown, the unlocking assembly includes a connecting member 22, which is fixed to the right front side of the first wedge block 21, and a first extrusion member 23 is slidably connected to the connecting member 22. A tension spring 24 is connected between the first extrusion member 23 and the connecting member 22, and the tension spring 24 is wound around the first extrusion member 23. The first extrusion member 23 is extruded and matched with the buckle 15.

[0035] When it is necessary to slag the smelting furnace 1, first push the trolley 11 backwards, so that the elastic telescopic member 110 enters from the opening of the smelting furnace 1 and contacts the inner rear wall of the smelting furnace 1, and adjust the vertical rod part of the inverted L-shaped fixing member 12 up and down, so that the two elastic telescopic members 110 extend 8 to 10 cm below the metal liquid surface, and then control the first multi-section electric push rod 13 to drive the double-sided rack 14 to move backwards, thereby driving the pusher 141 and the buckle 15 to move backwards. When the double-sided rack 14 moving backwards is engaged with the two first gears 18, the first gears 18 will The rotating part 19 is driven to rotate outward by 90°, thereby driving the elastic telescopic part 110 to flip outward to a horizontal state. The two elastic telescopic parts 110 will push the slag in the smelting furnace 1 forward, and the slag will gather on the inner front side of the smelting furnace 1. At the same time, the bottom of the two moving parts 17 will squeeze the buckle 15 to make it slide downward, and the force storage spring 16 will be compressed. When the buckle 15 moving backward passes over the moving part 17, under the elastic action of the force storage spring 16, the buckle 15 will slide upward and reset. At this time, the moving part 17 will be stuck between the pushing part 141 and the buckle 15.

[0036] Subsequently, control the first multi-section electric push rod 13 to drive the double-sided rack 14 to move forward, thereby driving the moving member 17, the rotating member 19, and the horizontally arranged elastic telescopic member 110 to move forward together. The elastic telescopic member 110 will gradually contract inward, causing the compression spring 111 to deform. When the elastic telescopic member 110 approaches the opening of the smelting furnace 1, the elastic telescopic member 110 will push all the slag in the smelting furnace 1 outwards. Then, control the first multi-section electric push rod 13 to drive the double-sided rack 14 to move backward, thereby driving the moving member 17, the rotating member 19, and the horizontally arranged elastic telescopic member 110 to move backward together. At the same time, under the elastic action of the compression spring 111, the elastic telescopic member 110 will extend to its initial length.

[0037] Then control the second multi-section electric push rod 2 to drive the first wedge block 21 to move downward, thereby driving the connecting member 22 and the first pressing member 23 to move downward. When the downward moving first pressing member 23 contacts the buckle 15, the first pressing member 23 will press on the buckle 15. As the first wedge block 21 drives the connecting member 22 to continue moving downward, the tension spring 24 will deform, and the first pressing member 23 will exert a downward pressure on the buckle 15, causing the buckle 15 to slide downward to a position lower than the moving member 17. The energy storage spring 16 will deform. At this time, control the first multi-section electric push rod 13 to drive the double-sided rack 14 to move backward. According to the previous steps, the rotating member 19 will drive the elastic telescopic member 110 to rotate inward until they are combined. When the buckle 15 passes over the moving member 17, under the elastic force of the energy storage spring 16, the buckle 15 slides upward to reset, and at the same time, under the elastic force of the tension spring 24, the first pressing member 23 moves downward to reset.

[0038] At this time, the trolley 11 can be pulled forward to move the elastic telescopic member 110 away from the smelting furnace 1. When the downward-moving first wedge block 21 contacts the scraping member 25, the first wedge block 21 will squeeze the scraping member 25 to move it backward, and the telescopic housing 26 will contract accordingly. The compression spring 28 will deform. The backward-moving scraping member 25 will scrape off the slag adhering to the elastic telescopic member 110. The staff can place a collection box below the elastic telescopic member 110 in advance, and the scraped slag will fall into the collection box. Finally, control the second multi-section electric push rod 2 to drive the first wedge block 21 to move upward to reset, and the connecting member 22 and the first pressing member 23 will move upward to reset accordingly. At the same time, under the elastic force of the compression spring 28, the scraping member 25 moves forward to reset, and the telescopic housing 26 returns to its original length. To sum up, through the mutual cooperation of the double-sided rack 14, the buckle 15, the first gear 18, the rotating member 19, the elastic telescopic member 110, etc., the slag in the smelting furnace 1 can be efficiently gathered together and removed. This not only expands the scope of slag removal but also improves the slag removal efficiency. Then, through the mutual cooperation of the first pressing member 23, the first wedge block 21, the scraping member 25, etc., the attached substances can be effectively removed, keeping the elastic telescopic member 110 clean and operating efficiently, further improving the slag removal efficiency.

[0039] Embodiment 2: On the basis of Embodiment 1, as Figure 9 shown, it further includes a slag-making mechanism for adding a slag-making agent into the smelting furnace 1 to promote the slag-making reaction. The slag-making mechanism is arranged on the inverted L-shaped fixing member 12. The slag-making mechanism includes a storage box 3. The top of the storage box 3 is provided with a lid. The storage box 3 is fixedly connected to the upper right side of the inverted L-shaped fixing member 12. Four symmetrically distributed discharge holes are opened on the bottom wall of the inverted L-shaped fixing member 12. A second guide rail 34 is fixedly connected to the lower left side of the storage box 3. A closing member 31 for controlling the opening and closing of the discharge holes is slidably connected to the second guide rail 34. The closing member 31 is slidably connected to the storage box 3. Two symmetrically distributed leakage holes are opened on the closing member 31. A spiral spring 35 is connected between the closing member 31 and the storage box 3. The spiral spring 35 is wound around the second guide rail 34. A second wedge block 32 is fixedly connected to the left side of the bottom of the closing member 31. A second pressing member 33 is fixedly connected to the right side of the double-sided rack 14. The second pressing member 33 and the second wedge block 32 are in extrusion cooperation.

[0040] As Figure 10 and Figure 11As shown in the figure, it further includes a protection mechanism for preventing the metal liquid carried out during the slag skimming process from splashing everywhere. The protection mechanism is arranged on the inverted L-shaped fixing member 12. The protection mechanism includes a collection box 4. The collection box 4 is fixedly connected to the lower part of the vertical rod of the inverted L-shaped fixing member 12. A sliding plate 401 is slidably connected in the collection box 4. A tension spring 45 is connected between the sliding plate 401 and the inner bottom wall of the collection box 4. The tension spring 45 is wound around the sliding plate 401. On the sliding plate 401, there are symmetrically distributed straight racks 41 on the left and right. Both straight racks 41 slide on the inner wall of the collection box 4. The top of the collection box 4 is rotatably connected with symmetrically distributed rotating shafts 42 on the left and right. On both rotating shafts 42, there are fixedly connected protection members 44. In the middle of both rotating shafts 42, there are fixedly connected second gears 43. The straight rack 41 and the adjacent second gear 43 are meshed with each other. All components of this device are made of high-temperature resistant materials.

[0041] When the first multi-section electric push rod 13 drives the double-sided rack 14 to move back and forth, it drives the second extrusion member 33 to move back and forth. The second extrusion member 33 moving back and forth will squeeze the second wedge-shaped block 32 to drive the closing member 31 to move to the right. The spiral spring 35 will deform. When the material leakage hole on the closing member 31 aligns with the discharge hole on the right side of the bottom of the storage box 3, the discharge hole on the left side of the bottom of the storage box 3 is no longer blocked by the closing member 31. The slag-making agent in the storage box 3 will flow out through the discharge hole into the smelting furnace 1, promoting the slag-making reaction in the smelting furnace 1. When the second extrusion member 33 passes over the second wedge-shaped block 32, under the elastic force of the spiral spring 35, the closing member 31 drives the second wedge-shaped block 32 to move to the left to reset, and the closing member 31 will seal the discharge hole of the storage box 3.

[0042] When the slag skimmed out by the elastic telescopic member 110 falls into the collection box 4 and presses on the sliding plate 401, under the action of the self-weight of the slag, the sliding plate 401 will be pressed downwards, the tension spring 45 will deform, and the straight rack 41 will move downwards accordingly. Since the straight rack 41 is meshed with the second gear 43, it drives the protection member 44 to turn inwards to cover the collection box 4, preventing the metal liquid carried out during the slag skimming process from splashing everywhere. When the slag cools down, the slag can be taken out of the collection box 4. Under the elastic force of the tension spring 45, the sliding plate 401 will drive the straight rack 41 to move upwards, and the protection member 44 will turn outwards to open. To sum up, first, through the cooperation of the second extrusion member 33, the second wedge-shaped block 32, the closing member 31, the storage box 3, etc., the efficient discharge of the slag-making agent is realized, thus promoting the slag-making reaction in the smelting furnace 1, providing strong support for the subsequent slag skimming operation. Then, through the cooperation of the sliding plate 401, the straight rack 41, the second gear 43, the protection member 44, etc., it effectively prevents the metal liquid carried out during the slag skimming process from splashing everywhere, not only improving the safety of the work, but also reducing environmental pollution and material waste.
