[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] like Figures 1-5 As shown, the technical solution adopted by this utility model is as follows: A mixing device for zirconium-alumina composite silicon carbide castable includes a mixing tank 1, and a rotating pipe 15 is rotatably connected inside the mixing tank 1. The rotating pipe 15 is arranged vertically. A water inlet device is provided at the top of the rotating pipe 15.

[0022] The water inlet device includes a water pump 13, which is fixedly connected to the top of the mixing tank 1. A first connecting pipe 14 is fixedly connected to the output end of the water pump 13, and the end of the first connecting pipe 14 is fixedly inserted through the top surface of the mixing tank 1. The end of the first connecting pipe 14 slidably abuts against the top end of a rotating pipe 15, and the first connecting pipe 14 communicates with the rotating pipe 15. The input end of the first water pump 13 is connected to a water source, enabling water to be introduced into the rotating pipe 15 through the first connecting pipe 14 without affecting the rotation of the rotating pipe 15.

[0023] A rotating assembly is provided on the top of the mixing tank 1, which drives the rotating tube 15 to rotate.

[0024] The rotating assembly includes a motor 5. An L-shaped mounting plate 4 is fixedly connected to the top of the mixing tank 1, and the top end of the motor 5 is fixedly connected to the mounting plate 4. The end of the output shaft of the motor 5 is rotatably connected to the top of the mixing tank 1, and a first gear 6 is fixedly sleeved on the output shaft of the motor 5. The motor 5 drives the first gear 6 to rotate.

[0025] The top of the rotating pipe 15 is fixedly fitted with a first rotating rod 9. The first rotating rod 9 is arranged horizontally.

[0026] A connecting sleeve 8 is rotatably fitted onto one end of the first connecting pipe 14, which is connected to the rotating pipe 15. The connecting sleeve 8 rotatably passes through the top surface of the mixing tank 1. A second gear 7 is fixedly fitted onto the top end of the connecting sleeve 8, and the second gear 7 meshes with the first gear 6. The first gear 6 drives the second gear 7 to rotate, causing the connecting sleeve 8 to rotate.

[0027] The bottom end of the connecting sleeve 8 is fixedly connected to the top of the first rotating rod 9. The connecting sleeve 8 seals the connection between the first connecting pipe 14 and the rotating pipe 15, so that the connecting sleeve 8 drives the first rotating rod 9 to rotate, and the rotating pipe 15 to rotate.

[0028] A second rotating rod 16 is fixedly sleeved at the bottom of the rotating tube 15, and the second rotating rod 16 corresponds vertically to the first rotating rod 9. A rotating sleeve 12 is rotatably connected to both ends of the first rotating rod 9 and the second rotating rod 16. The rotating sleeve 12 is parallel to the rotating tube 15. When the rotating tube 15 rotates, the rotating sleeve 12 is driven to rotate through the first rotating rod 9 and the second rotating rod 16.

[0029] Several stirring blades 21 are evenly arranged on the side of the rotating sleeve 12. The rotating sleeve 12 drives the stirring blades 21 to rotate, so that the stirring blades 21 stir and mix the materials in the mixing tank 1.

[0030] Each rotating sleeve 12 has three pairs of stirring blades 21, which are arranged at intervals from top to bottom on the rotating sleeve 12. The two stirring blades 21 in each pair are symmetrically arranged on the rotating sleeve 12.

[0031] Two pairs of first nozzles 22 are fixedly connected from top to bottom on the outer surface of the middle part of the rotating tube 15. The two first nozzles 22 in each pair are symmetrically fixed on the rotating tube 15.

[0032] Each first nozzle 22 has several first spray holes 23 spaced apart at its top and bottom. Each first spray hole 23 has a first one-way valve fixedly installed inside. The first one-way valve causes water in the first nozzle 22 to spray into the mixing tank 1. This allows water in the rotary pipe 15 to enter the first nozzle 22 and then be sprayed out through the first spray holes 23. When no water is being sprayed, the first one-way valve blocks the first spray holes 23, preventing material from the mixing tank 1 from entering the first nozzle 22.

[0033] The first nozzle 22 is movably positioned between two adjacent stirring blades 21, with the first spray hole 23 facing the corresponding stirring blade 21. This ensures that each stirring blade 21 can be sprayed with water, facilitating the rinsing of the stirring blades 21.

[0034] The mixing tank 1 is equipped with a first transmission assembly. When the rotating tube 15 rotates, the first transmission assembly drives the rotating sleeve 12 to rotate.

[0035] The first transmission assembly includes a gear ring 11, which is fixedly connected to the top surface of the inner cavity of the mixing tank 1. The gear ring 11 is coaxially arranged with the rotating pipe 15.

[0036] The top ends of both rotating sleeves 12 rotatably pass through the first rotating rod 9. A third gear 10 is fixedly connected to the top end of each of the two rotating sleeves 12, and both third gears 10 mesh with the gear ring 11. When the first rotating rod 9 drives the rotating sleeves 12 to rotate around the rotation axis of the rotating tube 15, the third gears 10 will rotate outside the gear ring 11, and the gear ring 11 will drive the third gears 10 to rotate, thereby causing the rotating sleeves 12 to rotate.

[0037] A second transmission assembly is installed inside the rotating sleeve 12. When the rotating sleeve 12 rotates, the second transmission assembly drives the stirring blade 21 to rotate.

[0038] The second transmission assembly includes a fixed shaft 17. The fixed shaft 17 is coaxially fixed inside the rotating sleeve 12, and its bottom end is fixedly connected to the top of the second rotating rod 16. A first bevel gear 18 is fixedly sleeved on the outer surface of the fixed shaft 17 at each of the two stirring blades 21 of a pair. This causes the rotating sleeve 12 to rotate outside of the first bevel gear 18 and the fixed shaft 17.

[0039] Each stirring blade 21 is fixedly connected to a rotating shaft 20 at one end, and the rotating shaft 20 is arranged horizontally. The rotating shaft 20 rotates through the side of the rotating sleeve 12.

[0040] A second bevel gear 19 is fixedly connected to one end of the rotating shaft 20 that extends into the rotating sleeve 12. The second bevel gear 19 meshes with the corresponding first bevel gear 18. The rotating sleeve 12 drives the second bevel gear 19 to rotate outside the first bevel gear 18. The first bevel gear 18 drives the second bevel gear 19 to rotate, thereby causing the rotating shaft 20 and the stirring blade 21 to rotate.

[0041] Connecting rods 24 are fixedly connected to both sides of the middle of the first rotating rod 9 and the second rotating rod 16. The first rotating rod 9 and the second rotating rod 16 cooperate with the two connected connecting rods 24 to form a cross-shaped structure.

[0042] The ends of two connecting rods 24 located on the same side are fixedly connected to the same scraper 25. The scraper 25 is vertically arranged and slides against the inner wall of the mixing tank 1.

[0043] A second nozzle 27 is fixedly connected between the ends of the other two connecting rods 24. The second nozzle 27 is fixedly connected to the rotating pipe 15 through the second connecting pipe 26. This causes the first rotating rod 9 and the second rotating rod 16 to drive the scraper 25 and the second nozzle 27 to rotate through the connecting rods 24, thereby cleaning the inner wall of the mixing tank 1.

[0044] One end of the second connecting pipe 26 is fixedly connected to the rotating pipe 15, and the other end of the second connecting pipe 26 is fixedly connected to the second spray pipe 27. This allows water in the rotating pipe 15 to enter the interior of the second spray pipe 27 through the second connecting pipe 26. The side of the second spray pipe 27 is provided with a plurality of second spray holes 28 spaced apart from top to bottom, with the second spray holes 28 facing the inner wall of the mixing tank 1. This allows the second spray holes 28 to spray water onto the inner wall of the mixing tank 1.

[0045] Each second nozzle 28 is equipped with a second one-way valve, which directs water from the second nozzle 27 into the mixing tank 1. When water is not being sprayed, the second one-way valve blocks the second nozzle 28 to prevent material from the mixing tank 1 from entering the second nozzle 27.

[0046] A feed inlet 2 is provided on the top side of the mixing tank 1, and a discharge outlet 3 is provided on the bottom of the mixing tank 1.

[0047] Working principle: When in use, the materials needed to prepare the zirconium-alumina composite silicon carbide castable are introduced into the mixing tank 1 through the feed port 2.

[0048] When motor 5 is started, the output shaft of motor 5 drives the first gear 6 to rotate, and the first gear 6 drives the second gear 7 to rotate. The second gear 7 drives the connecting sleeve 8 to rotate, and the connecting sleeve 8 rotates outside the first connecting pipe 14, thereby driving the first rotating rod 9 to rotate, causing the rotating pipe 15, the rotating sleeve 12, and the stirring blade 21 to rotate.

[0049] When the rotating sleeve 12 rotates around the rotation axis of the rotating tube 15, it will drive the third gear 10 to rotate outside the gear ring 11. The gear ring 11 will drive the third gear 10 to rotate, causing the rotating sleeve 12 to rotate.

[0050] Rotating the sleeve 12 causes the stirring blades 21 and the rotating shaft 20 to rotate outside the fixed shaft 17, causing the second bevel gear 19 to rotate outside the first bevel gear 18. The first bevel gear 18 then drives the second bevel gear 19 to rotate, causing the rotating shaft 20 and the stirring blades 21 to rotate. This mixes the materials in the mixing tank 1.

[0051] This allows the stirring blades 21 to rotate around the axis of rotation of the rotating tube 15, as well as around the axis of rotation of the rotating sleeve 12, and also to rotate on their own axis. These multiple rotation methods ensure more uniform mixing of the materials.

[0052] At the same time, the rotating pipe 15 will drive the scraper 25 and the second spray pipe 27 to rotate through the connecting rod 24, so that the scraper 25 scrapes the material on the inner wall of the mixing tank 1.

[0053] After the materials are mixed in the mixing tank 1, the mixed materials are discharged through the discharge port 3.

[0054] When the mixing tank 1 needs to be cleaned, connect the inlet of the water pump 13 to a water source. Start the water pump 13 to allow water to enter the first connecting pipe 14 and then the rotating pipe 15.

[0055] Water in the rotary pipe 15 enters the first nozzle 22 and is then sprayed out through the first nozzle 23. The first nozzle 23 sprays water toward the corresponding stirring blade 21 to rinse the stirring blade 21.

[0056] Water in the rotating pipe 15 enters the second spray pipe 27 through the second connecting pipe 26 and is sprayed onto the inner wall of the mixing tank 1 through the second spray hole 28 to rinse the mixing tank 1. The rotation of the rotating pipe 15 causes the second spray pipe 27 to spray water onto different parts of the inner wall of the mixing tank 1. The scraper 25 scrapes off the material on the inner wall of the mixing tank 1, causing the material to move downwards with the water flow and then be discharged through the discharge port 3.

[0057] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
