Description

Technical Field

[0001] This invention relates to the field of silicon carbide processing equipment technology, specifically to a silicon carbide acid pickling treatment equipment. Background Technology

[0002] During the production of silicon carbide micro powder, acidic solutions are needed to wash and remove impurities. The acidic solutions dissolve impurities such as iron oxide and magnesium oxide, thereby improving the purity of the produced silicon carbide micro powder and facilitating subsequent processing.

[0003] Most existing pickling equipment involves directly immersing silicon carbide micro powder in a pickling tank. During the pickling process, the silicon carbide micro powder tends to accumulate at the bottom of the container, resulting in insufficient contact with the acid and uneven impurity removal. After pickling, the container needs to be manually removed from the acid, which is not only cumbersome but also poses safety hazards to operators. Furthermore, it is impossible to stir the acid and silicon carbide micro powder during the pickling process, making it difficult to improve pickling efficiency. Manual stirring is not only labor-intensive but also exposes operators to acid corrosion, which can harm their health. Summary of the Invention

[0016] In this embodiment, the rotating component is a ball bearing.

[0017] Example 2, as Figure 1 - Figure 9As shown, the drive mechanism 8 includes a support frame 81 fixedly connected to the lifting mechanism 3. A rotating shaft 82 is rotatably connected to the support frame 81. One end of the rotating shaft 82 is fixedly connected to the lifting mechanism 3, and the other end of the rotating shaft 82 is fixedly connected to a first bevel gear 83. The first bevel gear 83 is connected to the translational stirring mechanism 7. A first gear 84 is fixedly connected to the outer surface of the rotating shaft 82. A drive motor 85 is fixedly mounted on the support frame 81. The drive end of the drive motor 85 is fixedly connected to a second gear 86 that meshes with the first gear 84. When the drive motor 85 is started, the drive motor 85 drives the second gear 86 to rotate. The second gear 86 meshes with the first gear 84 to rotate, which in turn drives the rotating shaft 82 to rotate. When the rotating shaft 82 rotates, it drives the second reciprocating screw 32 to rotate through the connecting rod 36. The first bevel gear 83 meshes with the second bevel gear 76 to rotate, which in turn drives the first reciprocating screw 74 to rotate.

[0018] The translational stirring mechanism 7 includes a column 71 fixedly connected to the top of the base plate 1. A translational plate 72 is fixedly connected to the top of the column 71. A placement groove 73 is opened on the top of the translational plate 72. A first reciprocating screw 74 is rotatably connected inside the placement groove 73. A connecting shaft 75 is fixedly connected to one end of the first reciprocating screw 74. A second bevel gear 76 is fixedly connected to the other end of the connecting shaft 75 extending out of the translational plate 72. The second bevel gear 76 is connected to the drive mechanism 8. A first slider 77 is threadedly connected to the outer surface of the first reciprocating screw 74. Both inner walls of the placement groove 73 are open. The system includes a first guide groove 78. First guide blocks 79 are fixedly connected to both sides of the first slider 77. The two sets of first guide blocks 79 are slidably connected to the interiors of the two sets of first guide grooves 78. A shaft seat 710 is fixedly connected to the bottom of the first slider 77. A stirring shaft 711 is fixedly connected to the inner ring of the shaft seat 710. The stirring shaft 711 is slidably connected to the interior of the sleeve 47.

Inside the placement groove 73, a toothed plate 714 is fixedly connected to one inner wall, and a third gear 715 is fixedly connected to the outer surface of the stirring shaft 711, meshing with the toothed plate 714. The start-up drive mechanism 8 drives the first bevel gear 83 to rotate, which in turn drives the second bevel gear 76 to rotate, thereby driving the first reciprocating screw 74 to rotate. The rotation of the first reciprocating screw 74 drives the first slider 77 to reciprocate along the first guide groove 78. When the first slider 77 moves, it drives the stirring shaft 711 to move synchronously. During the translation of the stirring shaft 711, its outer surface... The third gear 715 on the surface rolls along the toothed plate 714, thereby driving the stirring shaft 711 to rotate. The stirring shaft 711 drives the sleeve 47 and the stirring rod 48 to rotate synchronously through the positioning block 414. At the same time, when the stirring shaft 711 moves with the first slider 77, it can drive the sleeve 47 and the stirring rod 48 to move synchronously, so that the stirring rod 48 rotates while reciprocating within the placement frame 5, which fully stirs the silicon carbide micro powder and acid solution within the placement frame 5, avoids the accumulation of silicon carbide micro powder, and allows the silicon carbide micro powder and acid solution to fully and evenly contact each other, thereby improving the effect of acid washing and impurity removal.

[0019] Positioning plates 49 are fixedly connected to both sides of the bottom of the top plate 42. An installation groove 410 is provided on one side of the positioning plate 49. Placement plates 9 that cooperate with the installation groove 410 are fixedly connected to both sides of the placement frame 5.

A spring 413 is fixedly connected inside the limiting groove 411. One end of the spring 413 is fixedly connected to the limiting block 412. When the placement plates 9 on both sides of the placement frame 5 are aligned with the installation groove 410 on the positioning plate 49 and inserted, the placement plates 9 press the inclined surface of the limiting block 412, pushing the limiting block 412 to compress the spring 413 and retract into the limiting groove 411. When the placement plates 9 move to the other side of the limiting block 412, the spring 413 pushes the limiting block 412 to reset and pop out, thus limiting the placement plates 9.

[0020] The lifting mechanism 3 includes a connecting frame 31 fixedly connected to the base plate 1. A second reciprocating screw 32 is rotatably connected inside the connecting frame 31. A slide table 33 is slidably connected to the outer surface of the second reciprocating screw 32. One side of the slide table 33 is fixedly connected to the connecting plate 41. Second guide grooves 34 are provided on both inner walls of the connecting frame 31. Second guide blocks 35 are fixedly connected to both sides of the slide table 33. The two sets of second guide blocks 35 are slidably connected to the interiors of the two sets of second guide grooves 34. A connecting rod 36 is fixedly connected to one end of the second reciprocating screw 32. The other end of the connecting rod 36 is fixedly connected to the drive mechanism 8. When the drive motor 85 is started, the drive motor 85 drives the second gear 86 to rotate. The second gear 86 meshes and drives the first gear 84 to rotate, which in turn drives the rotating shaft 82 to rotate. When the rotating shaft 82 rotates, it drives the second reciprocating screw 32 to rotate through the connecting rod 36. The rotation of the second reciprocating screw 32 drives the slide table 33 to perform high-frequency up-and-down reciprocating motion along the second guide groove 34.

[0021] Working principle: In use, first, the silicon carbide micro powder to be pickled is loaded into the placement frame 5. Then, the placement plates 9 on both sides of the placement frame 5 are aligned with the mounting grooves 410 on the positioning plate 49 and inserted. During insertion, the placement plates 9 press against the inclined surface of the limiting block 412, pushing the limiting block 412 to compress the spring 413 and retract into the limiting groove 411. When the placement plate 9 moves to the other side of the limiting block 412, the spring 413 pushes the limiting block 412 to reset and pop out, thus limiting the placement plate 9 and completing the quick installation of the placement frame 5. Then, the drive motor 85 is started, and the drive motor 85 drives the second gear 8. When the first gear 84 rotates, the second gear 86 meshes with it, causing the first gear 84 to rotate, which in turn causes the rotating shaft 82 to rotate. When the rotating shaft 82 rotates, on the one hand, it drives the second reciprocating screw 32 to rotate through the connecting rod 36. The rotation of the second reciprocating screw 32 causes the slide table 33 to perform high-frequency up-and-down reciprocating motion along the second guide groove 34. This, in turn, drives the top plate 42 and the installed placement frame 5 to move up and down as a whole through the connecting plate 41. This allows the placement frame 5 to flow when immersed in the acid solution of the pickling tank 2, improving the pickling reaction efficiency. On the other hand, the rotation of the rotating shaft 82 will drive the first bevel gear 84 to rotate. 3. The first bevel gear 83 meshes with and drives the second bevel gear 76 to rotate, which in turn drives the first reciprocating screw 74 to rotate. The rotation of the first reciprocating screw 74 drives the first slider 77 to reciprocate and translate along the first guide groove 78. When the first slider 77 translates, it drives the stirring shaft 711 to translate synchronously. During the translation of the stirring shaft 711, the third gear 715 on its outer surface will roll along the tooth plate 714, thereby driving the stirring shaft 711 to rotate. The stirring shaft 711 drives the sleeve 47 and the stirring rod 48 to rotate synchronously through the positioning block 414. At the same time, the stirring shaft 711 moves with the first slider 77. During translation, the sleeve 47 and the stirring rod 48 can be driven to translate synchronously, so that the stirring rod 48 can rotate while reciprocating translation within the placement frame 5, which can fully stir the silicon carbide micro powder and acid solution within the placement frame 5, prevent the accumulation of silicon carbide micro powder, and ensure that the silicon carbide micro powder and acid solution are fully and evenly contacted, thereby improving the pickling and impurity removal effect. After pickling is completed, the drive mechanism 8 drives the lifting mechanism 3 to lift the placement frame 5 away from the pickling tank 2 as a whole, and then squeezes the limiting block 412 to retract it into the limiting groove 411, so that the placement frame 5 can be removed from the positioning plate 49 to complete the unloading. The operation is convenient.
