Technical Field

[0001] This utility model relates to the field of reaction vessels, and more specifically, to a hydrolysis reaction vessel for pharmaceutical excipients. Background Technology

[0002] Hydrolysis reaction vessels are experimental instruments widely used in fields such as chemistry, medicine, and food.

[0003] Many pharmaceutical excipient hydrolysis reaction tanks are quite tall. If any material is found to have been forgotten during the reaction, operators often need to use climbing equipment to open the tank lid to complete the replenishment. This not only consumes a lot of time and manpower and is complicated and cumbersome, but also poses a significant safety risk due to working at heights, which can easily lead to accidents and seriously affect production efficiency. In addition, frequent opening of the tank lid may also cause external impurities to enter the reaction system, interfering with the normal progress of the hydrolysis reaction.

[0004] Therefore, a hydrolysis reaction vessel for pharmaceutical excipients is proposed to address the above problems. Utility Model Content

[0005] 1. Technical problems to be solved

[0028] Example:

[0029] Please see Figure 1-4A hydrolysis reaction vessel for pharmaceutical excipients is disclosed. The vessel body 1 is cylindrical, and a mounting frame 14 is securely welded to its exterior. The mounting frame 14 is made of high-strength metal and has an overall frame structure. A screw 15 is horizontally arranged inside the mounting frame 14. Both ends of the screw 15 are rotatably connected to the mounting frame 14 via bearings, allowing the screw 15 to rotate smoothly 360 degrees within the mounting frame 14. The outer wall of the screw 15 has a standard threaded structure that matches the internal threaded hole of the moving block 17, thus achieving a threaded connection. When the screw 15 rotates, the moving block 17 can move linearly along the axial direction of the screw 15. A limit rod 16 is also fixedly connected inside the mounting frame 14. The limiting rod 16 and the screw 15 are arranged parallel to each other. The moving block 17 has a sliding hole that matches the limiting rod 16. The moving block 17 is slidably connected to the limiting rod 16 through the sliding hole. The limiting rod 16 is used to limit the movement direction of the moving block 17, ensuring that the moving block 17 can only move linearly along the axial direction of the screw 15, and will not rotate circumferentially with the rotation of the screw 15. The mounting bracket 14 is fixedly connected to the lower part of the mounting bracket 14 by bolts. The motor 25 is a three-phase asynchronous motor with forward and reverse rotation function. The output end of the motor 25 is fixedly connected to one end of the screw 15 through a coupling. When the motor 25 is powered on and started, it can convert electrical energy into mechanical energy and drive the screw 15 to rotate.

[0030] Please see Figure 1-4 Above the moving block 17, a feeding cylinder 18 is rotatably connected via a pin. The feeding cylinder 18 has a cylindrical structure, and sliders 19 are fixedly connected to both sides of its outer wall by welding. The sliders 19 are made of wear-resistant metal.

[0031] Please see Figure 1-4 Two curved grooves 22 are provided above the mounting bracket 14 corresponding to the position of the slider 19. The starting section of the groove 22 is consistent with the horizontal movement direction of the moving block 17, ensuring that the feeding cylinder 18 can move horizontally with the moving block 17. After approaching the designated position above the mounting bracket 14, the groove 22 gradually bends. The bending angle and path are precisely designed. When the slider 19 moves along this curved groove 22, the feeding cylinder 18 is driven by the slider 19 and will rotate along the curved path of the groove 22. Both sliders 19 can slide smoothly in the two grooves 22. The grooves 22 are used to precisely guide the movement trajectory of the feeding cylinder 18, so that it can not only move in a straight line in the horizontal direction with the moving block 17, but also rotate at a specific position according to a preset path, while ensuring the stability of the feeding cylinder 18 during the movement.

[0032] Please see Figure 1-4Two springs 21 are rotatably connected above the moving block 17 via pins. Their elastic coefficients are carefully adjusted to match the weight and rotation requirements of the feeding cylinder 18. The ends of the two springs 21 away from the moving block 17 are rotatably connected to the outer wall of the feeding cylinder 18 via pins. When the slider 19 moves in the slide groove 22, the spring 21 is in a stretched state and stores elastic potential energy. When the slider 19 leaves the slide groove 22, the elastic potential energy stored in the spring 21 is released, applying a pulling force to the feeding cylinder 18, causing the feeding cylinder 18 to rotate around the pin connected to the moving block 17, thereby realizing the reset action of the feeding cylinder 18 and restoring it to its initial horizontal placement state.

[0033] Please see Figure 1-4 The upper part of the moving block 17 is rotatably connected to the limiting frame 2 via a pin. The limiting frame 2 is made of metal and has magnetic material attached to its upper part by pasting or electroplating, so that the upper part of the limiting frame 2 is magnetic. The upper part of the limiting frame 2 can be attracted to the outer wall of the feeding cylinder 18, thereby playing a certain limiting role in the feeding cylinder 18 and preventing the feeding cylinder 18 from shaking or displacing excessively during movement.

[0034] One side of the limiting frame 2 is attached to the protrusion above the moving block 17. The protrusion is used to limit the rotation angle of the limiting frame 2, so that the limiting frame 2 can play a limiting role without affecting the normal rotation and movement of the feeding cylinder 18.

[0035] Please see Figure 1-4 The upper center of the tank body 1 has an inlet 11. The inlet 11 is circular and its diameter is designed according to actual production needs. It is used to add pharmaceutical excipients and related reaction reagents into the tank body 1.

[0036] A connecting pipe 23 is fixedly connected to the top of the tank body 1 by welding. The connecting pipe 23 has a cylindrical structure, with one end connected to the inside of the tank body 1 and the other end extending upward. A receiving cover 24 is fixedly connected to the top of the connecting pipe 23 by welding. The receiving cover 24 has a funnel-shaped structure, with its large opening facing upward and its small opening connected to the connecting pipe 23. The receiving cover 24 is located on one side of the mounting frame 14 and is used to collect the material poured from the discharge cylinder 18 in the above-mentioned rotating manner, and guide the material into the inside of the tank body 1 through the connecting pipe 23.

[0037] Please see Figure 1-4 A discharge port 12 is provided at the bottom of the outer wall of the tank body 1. The discharge port 12 has a circular structure and its diameter is designed according to actual production needs. It is used to discharge the pharmaceutical excipients after hydrolysis reaction from the inside of the tank body 1.

[0038] Support legs 13 are fixedly connected to the bottom of the tank body 1 by welding. There are four support legs 13, which are distributed in a rectangle at the bottom of the tank body 1 to support the tank body 1 and keep it in a stable position.

[0039] Working principle: The initial required pharmaceutical excipients and related reaction reagents are added into the tank 1 through the inlet 11 located at the top center. The inlet 11 is circular, with its diameter designed according to actual production needs to facilitate the addition of various materials. Simultaneously, the discharge cylinder 18, for subsequent material replenishment, is placed in its initial position. The discharge cylinder 18 is connected to the slide groove 22 above the mounting frame 14 via a slider 19. It is rotatably connected to the moving block 17 via a pin. Two tension springs 21 are connected between the moving block 17 and the discharge cylinder 18, and are in a naturally stretched state. The limiting frame 2 is rotatably connected to the moving block 17 via a pin. Its magnetic end is attached to the outer wall of the discharge cylinder 18, limiting excessive shaking of the discharge cylinder 18. One side of the limiting frame 2 is abutted against the protrusion above the moving block 17, limiting its own rotation angle.

[0040] If, shortly after the hydrolysis reaction begins, the operator discovers that some material has been forgotten to be added, there is no need to open the lid of tank 1. Simply restart motor 25, which will drive screw 15 to rotate, causing moving block 17 to move in the reverse direction. Discharge cylinder 18 will then move in the reverse direction as well.

[0041] The slider 19 of the discharge cylinder 18 slides back into the chute 22 and moves along the chute 22 to a designated position near the top of the mounting frame 14. At this time, the curved end of the chute 22 causes the discharge cylinder 18 to rotate. The operator adds any forgotten material to the discharge cylinder 18, and then the discharge cylinder 18 pours material into the receiving hood 24 again. The receiving hood 24 is funnel-shaped with its wide end facing upwards and is located on one side of the mounting frame 14. It is used to collect the material poured out of the discharge cylinder 18. After being collected by the receiving hood 24, the material flows into the tank 1 through the connecting pipe 23 welded below. The connecting pipe 23 is cylindrical, with one end connected to the receiving hood 24 and the other end communicating with the inside of the tank 1.

[0042] After the materials are added, including the initial materials and any possible supplementary materials, the hydrolysis reaction is carried out inside the tank 1. At this time, the tank 1 is in a closed state to ensure that the reaction is carried out in a stable environment. After the hydrolysis reaction is completed, the product is discharged through the discharge port 12 opened at the bottom of the outer wall of the tank 1.

[0043] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
