Description

Technical Field

[0001] This utility model relates to the technical field of additive devices, specifically a pharmaceutical intermediate additive device. Background Technology

[0002] Pharmaceutical intermediates are actually chemical raw materials or products used in the process of drug synthesis. These chemical products do not require a drug production license and can be produced in ordinary chemical plants. As long as they meet certain standards, they can be used in drug synthesis. In fact, drug synthesis also belongs to the chemical industry, but the requirements are more stringent than those for ordinary chemical plants. Therefore, pharmaceutical plants need GMP certification. Pharmaceutical intermediates are raw materials for drug synthesis, not drugs, so the requirements are relatively lower than those for drugs, and manufacturers of pharmaceutical intermediates do not need drug GMP certification.

[0003] Pharmaceutical intermediates involve the quantitative addition of raw materials during production and processing. Current methods typically involve weighing the raw materials and then pouring them into processing equipment, which is cumbersome, time-consuming, and severely impacts production efficiency. Therefore, those skilled in the art have proposed a pharmaceutical intermediate addition device to address the problems mentioned above. Utility Model Content

[0004] The purpose of this invention is to provide a pharmaceutical intermediate addition device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0008] As a further embodiment of this utility model: an inner box is installed on the upper inner wall of the inner cavity of the adding tube, and a second driving component is installed in the inner box. The output end of the second driving component is connected to the bottom end of the second rotating rod, and the top end of the second rotating rod is connected to the center of the bottom end of the movable circular plate.

[0009] As a further embodiment of this utility model: the position of the inner box is offset from the position of the feeding groove on the fixed circular plate, and the top of the inner box is inclined.

[0010] As a further embodiment of this utility model: a first rotating rod is provided inside the storage tank, a first driving component is installed at the center of the top of the storage tank, the output end of the first driving component is connected to the top of the first rotating rod, and a plurality of stirring rods are evenly distributed and connected to the outer wall of the first rotating rod.

[0011] As a further improvement of this utility model: a conical ring is connected to the top edge of the adding tube, and a conical tube is connected to the bottom end of the adding tube.

[0012] This invention has the following advantages: The device uses a sealing plate and an opening / closing component to cut a fixed quantity of raw material at once.

[0021] Example 1: Please refer to Figures 1 to 3 A pharmaceutical intermediate addition device includes a storage tank 1. An inlet pipe 2 and an outlet pipe 6 are connected to the top and bottom of the storage tank 1, respectively. A frame plate 7 is connected to both sides of the bottom of the storage tank 1. A slot 10 is provided on one side of the top of the outlet pipe 6, and a sealing plate 9 is inserted into the slot 10. A first telescopic member 8 is installed on the inner wall of one of the frame plates 7. The end of the first telescopic member 8 is connected to one end of the sealing plate 9 via a first connecting plate 12. A second telescopic member 11 is installed on one outer wall of the outlet pipe 6. An addition pipe 14 is inserted into the lower inner cavity of the outlet pipe 6, and the outer wall of the addition pipe 14 slides against the inner wall of the outlet pipe 6. The bottom end of the second telescopic member 11 is connected to the bottom outer wall of the addition pipe 14 via a second connecting plate 13. An opening and closing component 23 is provided at the top of the addition pipe 14.

[0022] Please see Figures 1 to 3 The opening and closing assembly 23 includes a fixed circular plate 16 and a movable circular plate 17, which are arranged vertically on the inner cavity of the top end of the adding tube 14. The bottom end of the fixed circular plate 16 is slidably attached to the top end of the movable circular plate 17. Both the fixed circular plate 16 and the movable circular plate 17 are provided with a feeding groove 18 on their sides. The movable circular plate 17 is rotatable. In this embodiment, an inner box 19 is installed on the upper inner wall of the inner cavity of the adding tube 14. A second driving member 20 is installed in the inner box 19. The output end of the second driving member 20 is connected to the bottom end of the second rotating rod 21. The top end of the second rotating rod 21 is connected to the center of the bottom end of the movable circular plate 17. The position of the inner box 19 is offset from the position of the feeding groove 18 on the fixed circular plate 16. The top end of the inner box 19 is inclined so as not to hinder the downward discharge of raw materials.

[0023] Example 2: See Figure 1 Based on Embodiment 1, a first rotating rod 4 is provided inside the storage tank 1, a first driving member 3 is installed at the center of the top of the storage tank 1, the output end of the first driving member 3 is connected to the top of the first rotating rod 4, and a plurality of stirring rods 5 are evenly distributed on the outer wall of the first rotating rod 4.

[0024] Please see Figure 1 , Figure 3 A tapered ring 22 is connected to the top edge of the adding tube 14, and a tapered tube 15 is connected to the bottom end of the adding tube 14 to facilitate the downward introduction of raw materials.

[0025] Working principle: In use, an appropriate amount of raw material is added to the storage tank 1 through the feed pipe 2. The drive component drives the first rotating rod 4 to rotate, which in turn drives the stirring rod 5 to rotate to stir the raw material. The storage tank 1 is installed above the pharmaceutical intermediate production and processing device through the frame plate 7. The material is discharged through the discharge pipe 6. The position of the adding pipe 14 is adjusted according to the discharge amount. First, the second drive component 20 drives the second rotating rod 21 to rotate, which in turn drives the movable circular plate 17 to rotate, so that the discharge groove 18 on the fixed circular plate 16 and the discharge groove 18 on the movable circular plate 17 are staggered. A telescopic component 8 drives the sealing plate 9 to move to the right, and the raw material in the storage tank 1 falls into and fills the area between the sealing plate 9 and the fixed circular plate 16. Then, the first telescopic component 8 drives the sealing plate 9 to move to the left, and the sealing plate 9 seals the top of the discharge pipe 6. At this time, the raw material to be discharged is completed. Then, the second driving component 20 drives the movable circular plate 17 to rotate, so that the discharge groove 18 on the movable circular plate 17 is aligned with the discharge groove 18 on the fixed circular plate 16. At this time, the discharged raw material is discharged downward through the discharge groove 18 and discharged into the pharmaceutical intermediate processing device along the bottom of the adding pipe 14 and the conical pipe 15.
