[0025] Furthermore, in the description of this utility model, unless otherwise explicitly defined, the terms "mounted," "connected," "connect," and "connector" should be interpreted broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.

[0026] The following will refer to the attached Figures 1 to 4 The present invention is described in detail with reference to the embodiments.

[0027] Example 1

[0028] A pharmaceutical intermediate mixing tank, comprising a base 1, a tank body 4 rotatably connected to the base 1, a rotary device for driving the tank body 4 to rotate, a stirring device disposed within the tank body 4, and a power device for moving the stirring device up and down within the tank body 4, wherein the rotary device and the stirring device rotate in opposite directions;

[0029] For example, if the tank body 4 rotates clockwise, the stirring device rotates counterclockwise. In this way, when the stirring device rotates at a constant speed, the pharmaceutical intermediate material in the tank body 4 rotates in the opposite direction, which will make the mixing speed faster and more uniform.

[0030] The rotating device includes a gear ring 9 fixedly connected to the tank body 4, a driving gear 10 meshing with the gear ring 9, and a reduction motor 8 whose output end is fixedly connected to the driving gear 10; the housing of the reduction motor 8 is fixedly connected to the base 1.

[0031] Since the tank body 4 is relatively heavy, especially after the pharmaceutical intermediate is added to the tank body 4, the rotation speed of the tank body 4 should not be too fast. The general rotation speed is about 8-15 revolutions per minute. If the rotation speed of the tank body 4 is high, the tank body needs to be dynamically balanced, which increases the production cost and is more complicated.

[0032] The base 1 is rotatably connected to the tank body 4 via a bearing 3 .

[0033] The stirring device includes a stirring shaft 5 , a stirring rod 6 mounted on the stirring shaft 5 , and a speed-regulating motor 15 driving the stirring shaft 5 to rotate.

[0034] The specific structure is that the stirring rod 6 is firmly welded to the stirring shaft 5 at one end, and the other end is open;

[0035] In order to facilitate the unloading of the mixed materials, the bottom of the tank body 4 is conical, and the part of the stirring rod 6 located in the cone is shorter than the part of the stirring rod 6 located in the cylindrical part of the tank body 4 to prevent the stirring rod 6 from colliding with the inner wall of the tank body 4.

[0036] The power unit includes a bracket 2 fixedly connected to the base 1, a slider 16 slidably connected to the bracket 2, and a drive device that drives the slider 16 to reciprocate; the stirring shaft 5 is rotatably connected to the slider 16; and the speed regulating motor 15 is fixedly connected to the slider 16. To prevent the slider 16 from rotating on the bracket 2, the slider 16 has a square cross-section, and the bracket 2 is provided with a square through-hole, in which the slider 16 can slide up and down.

[0037] like Figure 2 As shown, the stirring shaft 5 is rotatably connected to the slider 16 through two bearings;

[0038] like Figure 2 As shown, the stirring shaft 5 is provided with a connecting portion 51, and the size of the connecting portion 51 is larger than the diameter of the stirring shaft 5, so that the connecting portion 51 abuts against the inner ring of the bearing above, thereby preventing the stirring shaft 5 from falling off from the slider 16;

[0039] The connecting portion 51 is connected to the output end of the speed regulating motor 15 via a coupling;

[0040] The stirring shaft 5 is also provided with a retaining spring 52, which abuts against the inner ring of the bearing below; the retaining spring 52 and the connecting portion 51 limit the stirring shaft 5 and the slider 16 up and down to prevent the stirring shaft 5 from falling out of the inner hole of the bearing when the stirring shaft 5 moves up and down.

[0041] The drive device includes a drive motor fixedly connected to the bracket 2, a second gear 17 fixedly connected to the output end of the drive motor, and a rack provided on the slider 16. The second gear 17 meshes with the rack. The rotation of the second gear 17 drives the rack to move up and down, and the rack then drives the slider 16 to move up and down on the bracket 2.

[0042] The working process of this utility model is:

[0043] The components of the pharmaceutical intermediate are added into the tank body 4 according to the set ratio, and the reduction motor 8 is started, and the reduction motor 8 rotates (clockwise); the reduction motor 8 drives the ring gear 9 to rotate through the driving gear 10, and then drives the tank body 4 to rotate clockwise;

[0044] Start the speed regulating motor 15, the speed regulating motor 15 rotates counterclockwise, the speed regulating motor 15 drives the stirring shaft 5 to rotate, the stirring shaft 5 drives the stirring rod 6 to rotate in the tank body 1, so that the stirring rod 6 mixes the components of the pharmaceutical intermediate.

[0045] Start the rotary motor, the rotary motor drives the second gear 17 to rotate, and the second gear 17 drives the rack to move up and down. Since the rack is provided on the slider 16, the slider 16 can move up and down, and the slider 16 drives the stirring shaft 5 connected to it to move up and down, which can accelerate the mixing of the components of the pharmaceutical intermediate.

[0046] Example 2

[0047] The technical solution of this embodiment is similar to that of embodiment 1, except that:

[0048] like Figure 3 As shown, a plurality of protrusions 7 are provided on the inner wall of the tank body 4. The protrusions 7 are conical. When the tank body 4 rotates, the protrusions 7 and the stirring rod 7 work together to accelerate the mixing of the pharmaceutical intermediate.

[0049] Example 3

[0050] The technical solution of this embodiment is similar to that of embodiment 2.

[0051] The difference is that

[0052] like Figure 1 、 2 As shown, it also includes a limiting device provided on the bracket 2 to prevent the slider 16 from escaping from the bracket 2, and the limiting device includes an upper limit part 14, a lower limit part 11, a lower limit photoelectric switch 12 and an upper limit photoelectric switch 13.

[0053] The system further includes a controller, which is respectively connected to the reduction motor 8, the speed regulating motor 15, the drive motor, the upper limit photoelectric switch 13 and the lower limit photoelectric switch 12 for signals.

[0054] The upper limit portion 14 is located above the bracket 2 to prevent the slider 16 from falling out from above the bracket 2; the lower limit portion 11 is located below the bracket 2 to prevent the slider 16 from falling out from below the bracket 2;

[0055] The lower limit photoelectric switch 12 is located above the lower limit part 11. When the slider 16 blocks the lower limit photoelectric switch 12, the lower limit photoelectric switch 12 is triggered, and the lower limit photoelectric switch 12 sends a signal to the controller. The controller sends a reverse signal to the drive motor, and the drive motor drives the gear to reverse, and the gear drives the slider 16 to move upward;

[0056] The upper limit photoelectric switch 13 is located below the upper limit portion 14; when the slider 16 blocks the upper limit photoelectric switch 13, the upper limit photoelectric switch 13 sends a signal to the controller, and the controller sends a reverse signal to the drive motor. The drive motor drives the gear to reverse, and the gear drives the slider 16 downward through the rack. In this way, the stirring shaft 5 drives the stirring rod 6 to move up and down in the pharmaceutical intermediate, accelerating the mixing of the pharmaceutical intermediate and improving the mixing efficiency.

[0057] Example 4

[0058] The technical solution of this embodiment is similar to that of embodiment 4, except that:

[0059] A barrel cover is provided on the top of the tank body 4, and the barrel cover is slidably connected to the stirring shaft 5. The barrel cover can prevent foreign matter from entering when the pharmaceutical intermediate is mixed, thereby maintaining the purity of the pharmaceutical intermediate.
