Description

Technical Field

[0001] The utility model relates to the technical field of molybdenum dioxide preparation, in particular to a double-cone mixing device for molybdenum dioxide preparation. Background Art

[0002] The hydrogen reduction method is one of the most commonly used methods for preparing molybdenum dioxide. The specific steps include using hydrogen to reduce a mixture of ammonium dimolybdate and molybdenum trioxide. The reduction process is usually carried out in a rotary furnace, but can also be carried out in a multi-tube furnace. To improve the preparation efficiency of molybdenum dioxide, the raw material powders of ammonium dimolybdate and molybdenum trioxide need to be fully mixed before entering the furnace. The double-cone mixer is an important mixing equipment. By rotating the container, the material rolls, collides, and disperses inside the container, thereby achieving the purpose of mixing ammonium dimolybdate and molybdenum trioxide. However, the existing double-cone mixer has a relatively simple motion trajectory of the barrel. When mixing the materials, uneven mixing is likely to occur. In addition, in order to avoid excessive centrifugal force causing the material to stick to the wall, the rotation speed is low, resulting in a slow mixing speed. The single mixing time is long, which seriously restricts the overall production efficiency of molybdenum dioxide preparation. In view of this, in-depth research on the above problems has led to the creation of this case. Utility Model Content

[0010] The utility model provides a double-cone mixing device for preparing molybdenum dioxide.

Specifically, a swing drive mechanism is used to achieve swing control in the vertical direction, thereby achieving vertical mixing of the ammonium dimolybdate and molybdenum trioxide raw materials in the double-cone mixing drum.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] Example: In conjunction with the specification Figure 1-4 It can be seen that the present application specifically designs a double-cone mixing device for preparing molybdenum dioxide, including a base 1, a stand 2 and a double-cone mixing barrel 3. The stand 2 is mounted on the base 1, and the double-cone mixing barrel 3 is mounted on the annular frame 4 through a rotating support member. The two sides of the annular frame 4 are rotatably connected to the stand 2 through a fixed shaft 5. One end of the fixed shaft 5 is connected to a swing drive mechanism. A gear ring 6 is sleeved on the outer side of the double-cone mixing barrel 3. A lifting plate 17 is provided on the inner wall of the double-cone mixing barrel 3 along an annular array. A rotary drive mechanism is installed on the annular frame 4. A driving gear 7 is provided at the output end of the rotary drive mechanism. The driving gear 7 is meshed with the gear ring 6. A protective cover shell 16 is buckled on the outer side of the driving gear 7, which adopts radial rotation and vertical rotation. The rotary combination method is used to comprehensively control the movement trajectory of the double-cone mixing barrel 3, so that the ammonium dimolybdate and molybdenum trioxide raw material particles entering the double-cone mixing barrel 3 are evenly mixed. Specifically, the swing drive mechanism is used to realize the swing control in the vertical direction, so that the ammonium dimolybdate and molybdenum trioxide raw materials are mixed in the double-cone mixing barrel 3 in the vertical direction. At the same time, while the double-cone mixing barrel 3 is swinging in the vertical direction, the double-cone mixing barrel 3 itself is also under the action of the rotary drive mechanism, realizing radial rotation based on the central axis of the double-cone mixing barrel 3, thereby realizing the spiral motion of the material, thereby effectively enhancing the fluidity of the material, and greatly improving the mixing and stirring efficiency.

[0018] In the specific implementation process, as a preferred setting, the above-mentioned rotating support member includes an annular cylindrical guide rail 8, an arc-shaped slider 9 and an annular connecting seat 10. The annular cylindrical guide rail 8 is welded to the outside of the double-cone mixing barrel 3, and the arc-shaped slider 9 is slidably mounted on the annular cylindrical guide rail 8. The annular connecting seat 10 is welded to the outside of the arc-shaped slider 9 and is fixedly connected to the inner wall of the annular frame 4. The arc-shaped slider 9 and the annular cylindrical guide rail 8 are used to realize the rotational coordination between the double-cone mixing barrel 3 and the annular frame 4, so that the double-cone mixing barrel 3 can rotate inside the annular frame 4 under the cooperation of the rotary drive mechanism and the ring gear 6.

[0019] In the specific implementation process, as a preferred setting, the above-mentioned rotary drive mechanism includes a stepper motor 11, a first reducer 12 and an output shaft 13. The stepper motor 11 is installed on the annular seat and the driving end is connected to the input end of the first reducer 12. One end of the output shaft 13 is connected to the output end of the first reducer 12, and the other end is interference fit with the drive gear 7. When the stepper motor 11 is started, the output end of the stepper motor 11 rotates and drives the first reducer 12 to move. The output shaft 13 connected to the output end of the first reducer 12 directly drives the drive gear 7 to rotate. The rotation of the drive gear 7 drives the gear ring 6 meshing with it to rotate, thereby realizing the rotation control of the double-cone mixing barrel 3.

[0020] In the specific implementation process, as a preferred setting, the above-mentioned swing drive mechanism includes a servo motor 14 and a second reducer 15. The servo motor 14 is arranged on the side wall of the stand 2 and the driving end is connected to the input end of the second reducer 15. The output end of the second reducer 15 is connected to the fixed shaft 5. The driving end of the servo motor 14 is controlled to rotate back and forth at a constant speed, so that under the cooperation of the second reducer 15, the swing control of the fixed shaft 5 is realized, thereby realizing the swing movement of the annular frame 4 and the double-cone mixing barrel 3 in the vertical direction, further improving the vertical mixing efficiency of ammonium dimolybdate and molybdenum trioxide raw materials in the double-cone mixing barrel 3.
