It can be used to produce various molybdenum-containing chemical reagents and is also commonly used as a basic raw material for the production of molybdenum catalysts, molybdenum pigments, and other molybdenum chemical products. In existing technologies, the acid precipitation process in the preparation of ammonium molybdate requires the use of a reaction vessel.

[0016] 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.
[0017] Example: Refer to the appendix of the instruction manual Figure 1-3As can be seen, this application specifically designs an acid precipitation reactor for the preparation of ammonium molybdate, including an acid precipitation reactor body 1 and a top cover 2. The top cover 2 is mounted on the acid precipitation reactor body 1, and a fixing frame 3 is mounted on the top cover 2. A reciprocating drive mechanism is mounted on the fixing frame 3, and a support 4 is mounted on the moving end of the reciprocating drive mechanism. A drive control component is mounted on the support 4, and a hollow shaft tube 5 is connected to the output end of the drive control component. The hollow shaft tube 5 is rotatably connected to the support 4, and the lower end of the hollow shaft tube 5 extends into the acid precipitation reactor. The inner and outer walls of the vessel body 1 are slidably sealed to the top cover 2 via a sealing seat 6. A stirring shaft 7 is rotatably mounted inside the hollow shaft tube 5. The hollow shaft tube 5 and the stirring shaft 7 are rotatably sealed to each other via a sealing bearing 26. The upper end of the stirring shaft 7 is rotatably connected to the support 4. A first stirring blade 8 is provided at the lower end of the stirring shaft 7, and a second stirring blade 9 is provided on the hollow shaft tube 5. The output end of the drive control component is provided with a drive bevel gear 10, and a first bevel gear 11 is fixedly mounted on the stirring shaft 7. The upper fixed assembly is equipped with a second bevel gear 12. The first bevel gear 11 and the second bevel gear 12 are symmetrically arranged and mesh with the active bevel gear 10. This improves the existing acid precipitation reactor body 1. A reciprocating drive mechanism is integrated on the top cover 2. The reciprocating drive mechanism is used to realize the reciprocating adjustment control of the support 4 in the vertical direction, thereby realizing the vertical movement control of the hollow shaft tube 5 and the stirring shaft 7. At the same time, it works with the drive control component to realize the rotation control of the hollow shaft tube 5 and the stirring shaft 7. Under the action of the active bevel gear 10, the first bevel gear 11 and the second bevel gear 12, the first stirring blade 8 and the second stirring blade 9 can be rotated in opposite directions. This allows the first stirring blade 8 and the second stirring blade 9 to reciprocate in the vertical direction while performing bidirectional impact stirring of the ammonium molybdate raw material liquid. This effectively increases the stirring operation coverage area, improves the uniformity of mixing and stirring, accelerates the acid precipitation reaction rate in the ammonium molybdate preparation process, and improves production efficiency.
[0018] In a preferred embodiment, the reciprocating drive mechanism includes a drive motor 13, a reducer 14, a fixed arm 15, a support arm 16, and a sliding guide. The drive motor 13 is mounted on the fixed frame 3. The input end of the reducer 14 is connected to the output end of the drive motor 13. One end of the fixed arm 15 is fixedly connected to the output end of the reducer 14. The sliding guide is mounted on the side wall of the fixed frame 3. One end of the support arm 16 is rotatably engaged with the fixed arm 15, and the other end is rotatably connected to the moving end of the sliding guide. The sliding guide includes a guide rail 17, a movable seat 18, and a guide slider 19. The guide rail 17 is fixedly mounted on the fixed frame 3. On the side wall of frame 3, guide slider 19 is fixedly installed on one side of movable seat 18 and slides with guide rail 17. In use, the rotation control of fixed arm 15 is realized by the cooperation of drive motor 13 and reducer 14. During the rotation of fixed arm 15, support arm 16 is pulled to move. During the movement of support arm 16, movable seat 18 is pulled to slide along guide rail 17 in the vertical direction, so that support 4 on one side of movable seat 18 moves back and forth in the vertical direction, which in turn makes hollow shaft tube 5 and stirring shaft 7 move back and forth in the vertical direction, effectively increasing the stirring operation coverage area and improving mixing uniformity and mixing efficiency.
[0019] In the specific implementation process, as a preferred configuration, the top cover 2 is provided with an annular seat 20, the lower end face of the support 4 is welded with a connecting ring 21, and the hollow shaft tube 5 is fitted with a compression spring 22. The upper and lower ends of the compression spring 22 are fixedly connected to the connecting ring 21 and the annular seat 20 respectively. The elastic support of the compression spring 22 is used to improve the stability of the support 4 during reciprocating motion and to provide buffer elasticity.
[0020] In specific implementation, as a preferred configuration, the aforementioned drive control component includes a rotary motor 23, a reducer 24, and an output shaft 25. The reducer 24 is mounted on the support 4 and its input end is connected to the drive end of the rotary motor 23. The output shaft 25 is mounted on the output end of the reducer 24 and is fixedly connected to the drive bevel gear 10. By utilizing the cooperation between the rotary motor 23 and the reducer 24, the rotation control of the output shaft 25 is achieved. The rotation of the output shaft 25 drives the drive bevel gear 10 on one end of the output shaft 25 to rotate. The rotation of the drive bevel gear 10 drives the first bevel gear 11 and the second bevel gear 12 meshing with it to rotate synchronously in opposite directions, thereby achieving the rotation control of the stirring shaft 7 and the hollow shaft tube 5. The structure is simple and the operation is reliable.
