Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figures 1 to 6 This utility model provides a silicon carbide slurry mixing device, including a base 1, two L-shaped fixed columns 2 fixedly connected to the upper surface of the base 1, a mixing tank 3 fixedly connected to the opposite end of the two L-shaped fixed columns 2, a conveying pipe 4 fixedly connected to the upper surface of the mixing tank 3, a feeding hopper fixedly connected to the upper surface of the conveying pipe 4, a discharge pipe fixedly connected to the bottom of the mixing tank 3, a valve installed on the discharge pipe to facilitate opening the discharge pipe for material discharge, a dustproof box 5 fixedly connected to the upper surface of the mixing tank 3, a PLC control module fixedly installed on one side of the dustproof box 5, the PLC control module being electrically connected to a servo motor 601 to facilitate control of the operation of the servo motor 601, and a stirring structure 6 provided on the dustproof box 5;
[0032] To achieve bidirectional rotation, the stirring structure 6 includes a rotating shaft rotatably connected to one side of the dustproof box 5. A servo motor 601 is fixedly connected to one side of the dustproof box 5. The output shaft of the servo motor 601 is fixedly connected to the other end of the rotating shaft. A first conical tooth 602 is fixedly connected to one end of the rotating shaft. An outer sleeve column 603 is rotatably connected through the upper surface of the mixing tank 3. A second conical tooth 604 is fixedly connected to the outer sleeve column 603. The second conical tooth 604 meshes with the first conical tooth 602. An inner sleeve column 605 is rotatably connected inside the outer sleeve column 603. A third conical tooth 606 is fixedly connected to the upper surface of the inner sleeve column 605. The third conical tooth 606 meshes with the first conical tooth 602. The servo motor 601 drives the first conical tooth 602 to rotate through the rotating shaft. The first conical tooth 602 drives the inner sleeve column 605 to rotate through the third conical tooth 606. At the same time, the second conical tooth 604 drives the outer sleeve column 603 to rotate in the opposite direction, thereby improving the mixing uniformity.
[0033] To improve mixing efficiency, two stirring plates 607 are fixedly connected to the inner sleeve column 605, and a connecting column 608 is fixedly connected to the bottom of the inner sleeve column 605. Four guide scrapers 609 are fixedly connected to the connecting column 608. One side of each guide scraper 609 is in contact with the bottom of the mixing tank 3. The inner sleeve column 605 drives the two stirring plates 607 to rotate, stirring the silicon carbide slurry inside the mixing tank 3. At the same time, the inner sleeve column 605 drives the four guide scrapers 609 to rotate through the connecting column 608. The guide scrapers 609 push the slurry settled at the bottom of the mixing tank 3 upward, improving the mixing efficiency.
[0034] To improve mixing quality, a fixing ring 6010 is rotatably connected to the inner sleeve column 605. Two stirring rods 6011 are fixedly connected to both the fixing ring 6010 and the outer sleeve column 603. Each stirring rod 6011 has a moving groove on one side, and a push rod 6012 is slidably connected inside each moving groove. A spring 6014 is fixedly connected to one side inside each moving groove, and the other end of each spring 6014 is fixedly connected to one end of the corresponding push rod 6012. One end of the two push rods 6012 on the same side is fixedly connected to an arc-shaped scraper 6013. While the outer sleeve column 603 drives the stirring rods 6011 to stir, the elasticity of the springs 6014 causes the push rods 6012 to drive the corresponding arc-shaped scraper 6013 to fit tightly against the inner wall of the mixing tank 3. The arc-shaped scraper 6013 scrapes off the silicon carbide powder adhering to the inner wall of the mixing tank 3 and pushes it towards the center along the arc shape of the arc-shaped scraper 6013, thereby improving the mixing quality.
[0035] Working principle: The servo motor 601 drives the first conical tooth 602 to rotate via the rotating shaft. The first conical tooth 602 drives the inner sleeve column 605 to rotate via the third conical tooth 606, and simultaneously drives the outer sleeve column 603 to rotate in the opposite direction via the second conical tooth 604. The inner sleeve column 605 drives the two stirring plates 607 to rotate, stirring the silicon carbide slurry inside the mixing tank 3. At the same time, the inner sleeve column 605 drives the four guide scrapers 609 to rotate via the connecting column 608. The guide scrapers 609 push the slurry settled at the bottom of the mixing tank 3 upward, improving the stirring efficiency. While the outer sleeve column 603 drives the stirring rod 6011 to stir, the elasticity of the spring 6014 causes the push rod 6012 to drive the corresponding arc-shaped scraper 6013 to fit tightly against the inner wall of the mixing tank 3. The arc-shaped scraper 6013 scrapes off the silicon carbide powder adhering to the inner wall of the mixing tank 3 and pushes it towards the center along the arc surface of the arc-shaped scraper 6013, improving the mixing quality.
