Description

Technical Field

[0001] This utility model relates to the field of oxygen blowing technology for silicon casks, and in particular to a silicon cask oxygen blowing refining apparatus. Background Technology

[0002] In the silicon ladle oxygen blowing refining unit, the silicon ladle is a special container used for storing and quantitatively adding silicon materials. Its core function is to cooperate with the oxygen blowing process to realize the metallurgical reaction of silicon liquid. The silicon ladle and the oxygen blowing unit work together to not only efficiently remove impurities in silicon, but also adjust the composition of silicon liquid and improve product quality. It is an indispensable key equipment in modern refining process. When the silicon liquid is poured out of the silicon ladle, a large amount of silicon slag will remain on the inner wall of the silicon ladle.

[0003] Currently, the cleaning of silicon slag inside silicon ladles mostly relies on manual operation. Workers need to use tools such as long-handled slag rakes and steel bars to enter the high-temperature environment for cleaning. This cleaning method has many drawbacks. On the one hand, manual cleaning is inefficient, consuming a lot of manpower and time, and affecting the production progress. On the other hand, the high-temperature environment poses a great threat to the health of workers, and is prone to safety accidents such as burns. Moreover, manual cleaning cannot guarantee thorough cleaning, and silicon slag may remain on the inner wall, affecting the quality of subsequent silicon liquid. Therefore, there is an urgent need for a device that can efficiently and safely clean silicon slag inside silicon ladles.

[0004] Therefore, it is necessary to provide a new silicon-bagged oxygen-blowing refining apparatus to solve the above-mentioned technical problems. Utility Model Content

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.

[0030] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0031] Please see Figures 1 to 6 A silicon bag oxygen blowing refining device includes: a transfer track 1, a transfer car 2 installed on the top of the transfer track 1, a silicon bag body 3 fixedly connected to the top of the transfer car 2, a support 4 provided on the top of the transfer track 1, cleaning scrapers 5 for cleaning silicon slag equidistantly arranged inside the support 4, a connecting rod 6 fixedly connected to the top of the cleaning scraper 5, a clamping plate 7 fixedly connected to the side of the cleaning scraper 5 away from the silicon bag body 3, a lifting component for raising and lowering the cleaning scraper 5 installed inside the support 4, a rotating component for rotating the cleaning scraper 5 installed inside the support 4, the length of the connecting rod 6 being greater than the height inside the silicon bag body 3, the side of the cleaning scraper 5 away from the clamping plate 7 having an arc design, and the side of the clamping plate 7 away from the cleaning scraper 5 having a toothed design.

[0032] It should be noted that the cleaning scraper 5, clamping plate 7, and connecting rod 6 are all made of high-temperature resistant materials. They will not be deformed or damaged due to high temperatures when cleaning silicon slag inside the silicon casing 3. The stroke of the threaded part of the threaded rod 24 is greater than the height inside the silicon casing 3. The longer connecting rod 6 and the threaded stroke allow the cleaning scraper 5 to descend a greater distance to adapt to silicon casings 3 of different heights. The arc-shaped design of one side of the cleaning scraper 5 can fit against the cylindrical inner wall of the silicon casing 3 to ensure cleaning efficiency. The toothed clamping plate 7 can maintain stability during clamping.

[0033] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 The lifting assembly includes: a first drive motor 21, a driving bevel gear 22, a driven bevel gear 23, a threaded rod 24, a threaded sleeve 25, a fixing ring 26, a first slide rod 27, and a guide plate 28. The first drive motor 21 is fixedly connected inside the bracket 4. The output end of the first drive motor 21 is fixedly connected to the driving bevel gear 22. The driven bevel gear 23 is rotatably connected inside the bracket 4. The driving bevel gear 22 meshes with the driven bevel gear 23. The threaded rod 24 is rotatably connected inside the bracket 4. The top of the threaded rod 24 is fixedly connected to the driven bevel gear 23. The outer wall of the threaded rod 24 is threadedly connected to the threaded sleeve 25. The top of the threaded sleeve 25 is fixedly connected to the fixing ring 26. The top of the fixing ring 26 is symmetrically fixedly connected to the first slide rod 27. The first slide rod 27 passes through the bracket 4 and is slidably connected to the bracket 4. The outer wall of the threaded sleeve 25 is rotatably connected to the guide plate 28. The bottom of the guide plate 28 is provided with guide rails 29 at equal intervals. Multiple sets of connecting rods 6 slide inside the corresponding guide rails 29.

[0034] It should be noted that: the top of the first slide rod 27 extends out of the top of the bracket 4 and descends with the descent of the fixing ring 26. The fixing ring 26 and the first slide rod 27 restrict the threaded sleeve 25 from rotating with the threaded rod 24. The threaded sleeve 25 is rotatably connected to the guide plate 28. When the guide plate 28 rotates, it will not drive the threaded sleeve 25 to rotate. However, when the threaded sleeve 25 descends, it will drive the guide plate 28 to slide downward along the second slide rod 34.

[0035] Please see Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 The rotating assembly includes: a second drive motor 31, a first gear 32, a second gear 33, and a second slide bar 34. The second drive motor 31 is fixedly connected inside the bracket 4. The output end of the second drive motor 31 is fixedly connected to the first gear 32. The second gear 33 is rotatably connected inside the bracket 4. The first gear 32 meshes with the second gear 33. The second slide bar 34 is fixedly connected at equal intervals to the bottom of the second gear 33. The second slide bar 34 passes through the guide plate 28 and is slidably connected to the guide plate 28. The second gear 33 is hollow inside. The two first slide bars 27 pass through the hollow part of the second gear 33.

[0036] It should be noted that the hollow design of the second gear 33 ensures that the movement of the threaded rod 24, the first slide rod 27, and the second gear 33 does not affect each other.

[0037] The working principle of the silicon ladle oxygen blowing refining device provided by this utility model is as follows:

[0038] Initial preparation:

[0039] The transfer vehicle 2 moves the silicon bag body 3, which contains silicon slag after the silicon liquid has been poured out, along the transfer track 1 to the area below the support 4, so that the center of the silicon bag body 3 is on the axis of the guide plate 28, in preparation for the cleaning work.

[0040] Cleaning scraper 5 descends and rotates:

[0041] The first drive motor 21 of the lifting assembly is activated, driving the active bevel gear 22 to rotate. The active bevel gear 22 meshes with the driven bevel gear 23, causing the driven bevel gear 23 to drive the threaded rod 24 to rotate. Since the threaded rod 24 is threadedly connected to the threaded sleeve 25, a fixing ring 26 is fixedly connected to the outer wall of the threaded sleeve 25, and a second sliding rod 34 is fixedly connected to the top of the fixing ring 26. The second sliding rod 34 can only slide inside the bracket 4, so the threaded sleeve 25 will not rotate with the threaded rod 24. At this time, the threaded sleeve 25 will move downward with the rotation of the threaded rod 24. At the same time, the fixing ring 26 and the first sliding rod 27 also descend. The guide plate 28, which is rotatably connected to the outer wall of the threaded sleeve 25, will also descend synchronously. A connecting rod 6 is slidably connected inside the guide rail 29 at the bottom of the guide plate 28, causing the connecting rod 6 to also descend. The cleaning scraper 5 at the bottom of the connecting rod 6 descends into the silicone. Inside the package body 3, as the cleaning scraper 5 descends, the second drive motor 31 of the rotating assembly is activated. The second drive motor 31 drives the first gear 32 to rotate. The first gear 32 meshes with the second gear 33, causing the second gear 33 to rotate counterclockwise. The second slide rod 34, which is fixedly connected to the bottom of the second gear 33, rotates accordingly. Since the second slide rod 34 is slidably connected to the guide plate 28, it drives the guide plate 28 to rotate counterclockwise. As a result, the connecting rod 6 slides in the guide rail 29 under the action of centrifugal force, gradually moving away from the axis of the guide plate 28. When the connecting rod 6 reaches the farthest point from the axis of the guide plate 28, the arc-shaped surface of the cleaning scraper 5 adheres to the inner wall of the silicone package body 3. The rotation of the connecting rod 6 drives the cleaning scraper 5 to rotate during the descent. The rotating and descending cleaning scraper 5 scrapes the silicone slag on the inner wall of the silicone package body 3, causing the silicone slag to gradually fall off and fall into the bottom of the silicone package body 3.

[0042] Silicon slag trapping and rising:

[0043] After the cleaning scraper 5 descends to the bottom of the silicon bag body 3 and completes the inner wall cleaning, the second drive motor 31 drives the guide plate 28 to rotate clockwise. During the rotation of the guide plate 28, the connecting rod 6 slides in the guide rail 29. Due to the special design of the guide rail 29, the clamping plate 7 and the cleaning scraper 5 will move close to the axis of the silicon bag body 3, thereby clamping the silicon slag at the bottom of the silicon bag body 3. Then, the first drive motor 21 of the lifting component reverses, causing the threaded rod 24 to rotate in the opposite direction and the threaded sleeve 25 to rise, driving the cleaning scraper 5 and the clamped silicon slag to rise together, finally removing the silicon slag from the silicon bag body 3 and completing the cleaning work.

[0044] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
