Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0019] Embodiment: Such as Figures 1-7As shown in the figure, an embodiment of the present invention provides a raw material mixing device for the production of silicon carbide ceramics, which includes a mixing workbench 1. Two first support frames 2 are fixedly connected to the upper surface of the mixing workbench 1. A horizontal mixing cylinder 3 is fixedly connected between the two first support frames 2. A feed hopper 35 is fixedly connected to the top of the outer surface of the horizontal mixing cylinder 3. A second support frame 4 is arranged on one side of the horizontal mixing cylinder 3. Two rectangular blocks are fixedly connected to the upper surface of the second support frame 4. A guiding installation rod 5 is fixedly connected between the two rectangular blocks. A horizontal moving plate 6 is slidably connected to the outer surface of the guiding installation rod 5; A first power assembly for driving the horizontal moving plate 6 to move is installed on the side wall of one of the rectangular blocks. The first power assembly includes a first servo motor 7 fixedly connected to the side wall of the rectangular block. The output shaft of the first servo motor 7 is fixedly connected with a threaded rotating rod 8. The horizontal moving plate 6 is threadedly connected to the outer surface of the threaded rotating rod 8; A first rotating rod 9 is rotatably connected through the side wall of the horizontal moving plate 6. A second power assembly for driving the first rotating rod 9 to rotate is installed on the horizontal moving plate 6. The second power assembly includes a second servo motor 11 fixedly connected to the side wall of the horizontal moving plate 6. The output shaft of the second servo motor 11 is fixedly connected with a second rotating gear 12. A first rotating gear 10 is fixedly connected to the outer surface of the first rotating rod 9. The first rotating gear 10 is meshed and connected with the second rotating gear 12; An end blocking plate 13 and four first stirring plates 14 are fixedly connected to the outer surface of the first rotating rod 9. The first stirring plates 14 communicate with the first rotating rod 9. Both the first stirring plates 14 and the first rotating rod 9 are hollow, and the connection parts of both are openings to ensure their communication. The end blocking plate 13 and the four first stirring plates 14 are all located inside the horizontal mixing cylinder 3. The end blocking plate 13 is located inside one side of the horizontal mixing cylinder 3 and is slidably sealed with the horizontal mixing cylinder 3. A second rotating rod 15 is slidably connected to the outer surface of the first rotating rod 9. Two first sliding blocks 28 are fixedly connected to the outer surface of the first rotating rod 9.

A first sealing ring 29 is fixedly connected to the inner wall of the second rotating rod 15. The outer surface of the first rotating rod 9 is attached to the first sealing ring 29. The first rotating rod 9 drives the end blocking plate 13 to move into the horizontal mixing cylinder 3, so that the end blocking plate 13 pushes the materials inside the horizontal mixing cylinder 3 to one side, making the materials be stirred in a smaller space. When the end blocking plate 13 moves, it will scrape the raw materials on the inner wall of the horizontal mixing cylinder 3. Moreover, the end blocking plate 13 rotates together with the first rotating rod 9, which is beneficial to throwing off the raw materials adhered to the end blocking plate 13; Four second stirring plates 16 are fixedly connected to the second rotating rod 15.

The linkage installation rod 19 is fixedly connected between the third stirring plate 18 and the corresponding second stirring plate 16. A plurality of stirring short plates 20 are fixedly connected to the outer surface of the linkage installation rod 19. Through the cooperation of the linkage installation rod 19 and the plurality of stirring short plates 20, the raw materials can be effectively assisted in stirring. When the second rotating rod 15 moves, the second stirring plate 16 drives the third stirring plate 18 to move through the linkage installation rod 19, so that the first stirring plate 14, the second stirring plate 16 and the third stirring plate 18 can stir in a small range of space; One end of the third rotating rod 17 is fixedly communicated with an installation pipe 23. One end of the installation pipe 23 penetrates and extends to the outside of the horizontal mixing cylinder body 3, and the installation pipe 23 is rotationally connected with the horizontal mixing cylinder body 3. A water supply component is installed on the mixing workbench 1. The water supply component includes a water pump body 21 fixedly connected to the mixing workbench 1. The outlet of the water pump body 21 is fixedly connected with a first connecting pipe 22. One end of the first connecting pipe 22 away from the water pump body 21 is rotationally connected with the installation pipe 23. One end of the first rotating rod 9 is connected with a drainage component. The drainage component includes a second connecting pipe 24 rotationally connected to the end of the first rotating rod 9. One end of the second connecting pipe 24 away from the first rotating rod 9 is fixedly connected with a third connecting pipe 25.

The other end of the connecting fixed rod 26 is fixedly connected with the second connecting pipe 24 to ensure that the second connecting pipe 24 does not rotate with the first rotating rod 9.

[0020] Working principle: During use, the production raw materials are put into the interior of the horizontal mixing cylinder body 3 through the feed hopper 35, and then the second servo motor 11 is started. The output shaft of the second servo motor 11 drives the second rotating gear 12 to rotate, so that the first rotating gear 10 drives the first rotating rod 9 to rotate. The first rotating rod 9 drives the second rotating rod 15 and the third rotating rod 17 to rotate, so that the first stirring plate 14, the second stirring plate 16 and the third stirring plate 18 rotate to mix and stir the raw materials. During the stirring process, the water pump body 21 is started. The water pump body 21 pumps cold water into the first connecting pipe 22, then enters the installation pipe 23 through the first connecting pipe 22, and then passes through the third rotating rod 17, the second rotating rod 15, the first rotating rod 9, and the second connecting pipe 24 in sequence, and finally is discharged through the third connecting pipe 25. When the cold water passes through the first rotating rod 9, it will enter the interior of the first stirring plate 14, thereby cooling the raw materials during the stirring process, which is beneficial to improving the stirring and cooling effect of the raw materials. The third rotating rod 17, the second rotating rod 15, and the first rotating rod 9 are all arranged in the middle and have openings at both ends. After stirring for a period of time, the first servo motor 7 is started. The output shaft of the first servo motor 7 drives the threaded rotating rod 8 to rotate, so that the horizontal moving plate 6 moves horizontally on the outer surface of the threaded rotating rod 8, thereby driving the first rotating rod 9 to move into the interior of the second rotating rod 15, and the second rotating rod 15 moves into the interior of the third rotating rod 17. The first rotating rod 9 drives the end sealing plate 13 to move into the interior of the horizontal mixing cylinder body 3, so that the end sealing plate 13 pushes the materials inside the horizontal mixing cylinder body 3 to one side, so that the materials are stirred in a smaller space. After stirring for a period of time, the end sealing plate 13 retracts, allowing the raw materials to be dispersed again. Repeat the above process several times, which greatly improves the stirring effect of the raw materials.
