Description

Technical Field

[0001] This utility model relates to the technical field of medical devices, and in particular to a mixing device for raw materials used in the production of pharmaceutical intermediates. Background Technology

[0002] Pharmaceutical intermediate production raw material mixing devices are mainly used to uniformly mix multiple raw materials to ensure the quality and production stability of pharmaceutical intermediates. In the production of pharmaceutical intermediates, multiple liquid raw materials need to be poured into the mixing device for mixing. In the prior art, utility model patent application number 202322264035.3 discloses a pharmaceutical intermediate production preparation mixing device, which mainly consists of a box, mixing components, and a stirring rod. In use, various raw materials are poured into the box, and then the mixing components mix the various raw materials in the box. However, this device has the following problem: it only has the function of stirring and mixing raw materials. After the raw materials are stirred, it is necessary for staff to take samples, and then test the samples. After passing the test, the stirred raw materials are discharged from the box. However, the aforementioned prior art device does not have the function of sampling the stirred raw materials, making it inconvenient to use and impractical. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a pharmaceutical intermediate production raw material mixing device that can assist workers in sampling the mixed liquid after stirring the raw materials, making it convenient to sample the raw materials, easy to use, and highly practical.

[0004] This utility model discloses a mixing device for raw materials used in the production of pharmaceutical intermediates. It includes a support frame, a support plate, and a housing. The housing is fixedly mounted on the upper end of the support frame via the support plate. The housing contains a chamber, and a feeding port and a discharge port are respectively located at the upper and lower ends of the housing, each equipped with a valve. It also includes a stirring mechanism and a sampling mechanism, both mounted on the support frame. The stirring mechanism performs stirring, and the sampling mechanism performs sampling. During the production of medical intermediates, various liquid raw materials are first added to the chamber of the housing. Then, the stirring mechanism is activated to stir the multiple groups of liquid raw materials within the chamber. After stirring, a portion of the stirred liquid is taken from the chamber using the sampling mechanism. The sampled liquid is then tested. If the test is satisfactory, the stirred liquid is removed. If the test is unsatisfactory, the missing raw material is added back to the chamber based on the test results, and stirring continues. This device assists workers in sampling the stirred liquid after the raw materials are stirred, facilitating raw material sampling and offering convenient and highly practical operation.

[0005] Preferably, the stirring mechanism includes a motor, a rotating shaft, and multiple sets of stirring blades. The motor is fixedly mounted on the upper end of the housing, the rotating shaft is rotatably mounted on the housing, and the upper end of the rotating shaft is connected to the output end of the motor. The multiple sets of stirring blades are all fixedly mounted on the rotating shaft and are located within the chamber of the housing. When the raw materials in the chamber are stirred and mixed, the motor is turned on, and the motor causes the multiple sets of stirring blades to rotate through the rotating shaft. During the rotation of the multiple sets of stirring blades, the movement of various raw materials in the chamber is promoted, and the mixing of various raw materials is promoted.

[0006] Preferably, the sampling mechanism includes a lifting mechanism, a sealing mechanism, a delivery pump, a delivery hose, and a sampling tube. The delivery pump is mounted on a bracket and has a discharge pipe. The input end of the delivery pump is connected to the sampling tube via the delivery hose. The upper end of the sampling tube is sealed, and the lower end is open. The sealing mechanism is used to seal the opening at the lower end of the sampling tube. The sampling tube is located inside the chamber of the housing and is mounted on the lifting mechanism, which is used to lift the sampling tube. When sampling the liquid inside the chamber, the lifting mechanism is opened to lower the sampling tube into the raw material liquid inside the chamber. Then, the delivery pump is turned on so that the raw material inside the chamber is discharged sequentially through the sampling tube, the delivery hose, and the delivery pump for collection. This facilitates the sampling of the raw material liquid inside the chamber.

[0007] Preferably, the lifting mechanism includes a hydraulic cylinder A and a push rod. The hydraulic cylinder A is fixedly installed at the upper end of the housing, and the output end of the hydraulic cylinder A is provided with a push rod. The push rod is slidably installed on the housing, and the upper end of the push rod is connected to the output end of the hydraulic cylinder A. The sampling tube is fixedly installed at the lower end of the push rod. When sampling the liquid in the housing chamber, the hydraulic cylinder A is opened, and the hydraulic cylinder A adjusts the height of the sampling tube through the push rod, thereby immersing the sampling tube in the raw material liquid in the housing chamber, and then the raw material liquid can be sampled. Since the height of the sampling tube can be adjusted, liquid can be sampled at any height in the housing chamber, which is convenient to use and highly practical.

[0008] Preferably, the sealing mechanism includes a hydraulic cylinder B, a lifting rod, and a sealing plate. The hydraulic cylinder B is fixedly installed on the upper end of the bracket, and the lifting rod is slidably installed on the housing. The lower end of the lifting rod is connected to the output end of the hydraulic cylinder B. The sealing plate is fixedly installed on the upper end of the lifting rod and is located below the sampling tube. When sampling the raw material liquid at a specified height in the housing chamber, the sampling tube is first positioned above the liquid surface. Then, the hydraulic cylinder B is opened, and the hydraulic cylinder B raises the sealing plate via the lifting rod, so that the upper end of the sealing plate contacts the lower end of the sampling tube, sealing the opening at the lower end of the sampling tube. Then, the sampling tube is lowered, and at the same time, the hydraulic cylinder B lowers the sealing plate along with the lifting rod, ensuring that the speed at which the sealing plate descends matches the speed at which the sampling tube descends. This ensures that the sampling tube is blocked by the sealing plate as it descends in the raw material liquid, preventing liquid from other heights from entering the sampling tube. This continues until the sampling tube reaches the specified height in the liquid, at which point the sealing plate separates from the sampling tube, allowing the sampling tube to collect the sample. This improves the accuracy of the sampling.

[0009] Preferably, a sealing pad is provided at the upper end of the sealing plate; this arrangement improves the sealing effect of the sealing plate on the sampling tube.

[0010] Preferably, a temperature gauge is installed on the chamber; this facilitates the monitoring of the temperature of the raw material liquid inside the chamber.

[0011] Compared with the prior art, the beneficial effects of this utility model are: after stirring the raw materials, it can assist the staff in taking samples of the stirred liquid, which facilitates the sampling of raw materials, is convenient to use, and has high practicality.

[0018] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete.

[0019] Example 1

[0020] like Figures 1 to 5 The pharmaceutical intermediate raw material mixing device of this utility model includes a support 1, a support plate 2, a box 3, a stirring mechanism, and a sampling mechanism. The box 3 is fixedly installed on the upper end of the support 1 via the support plate 2. A chamber is provided inside the box 3. A feeding port and a discharge port are respectively provided at the upper and lower ends of the box 3, and valves are provided on both the feeding and discharge ports. The stirring mechanism and the sampling mechanism are both installed on the support 1. The stirring mechanism has a stirring function, and the sampling mechanism has a sampling function. In the production of medical intermediates, various liquid raw materials are first added to the chamber of the box 3, and then... The stirring mechanism is activated to agitate multiple liquid raw materials within the three chambers of the tank. After agitation is complete, a portion of the agitated liquid is taken from the three chambers via a sampling mechanism. The sampled liquid is then tested. If the test is satisfactory, the agitated liquid is removed. If the test is unsatisfactory, the missing raw materials are added back to the three chambers based on the test results, and the mixing process continues. This system assists staff in sampling the agitated liquid after agitation, making raw material sampling convenient, easy to use, and highly practical.

[0021] like Figure 1 and Figure 4 The stirring mechanism includes a motor 4, a rotating shaft 5, and multiple sets of stirring blades 6. The motor 4 is fixedly installed on the upper end of the housing 3, and the rotating shaft 5 is rotatably installed on the housing 3. The upper end of the rotating shaft 5 is connected to the output end of the motor 4. The multiple sets of stirring blades 6 are all fixedly installed on the rotating shaft 5 and are all located in the chamber of the housing 3. When the raw materials in the chamber of the housing 3 are stirred and mixed, the motor 4 is turned on. The motor 4 causes the multiple sets of stirring blades 6 to rotate through the rotating shaft 5. During the rotation, the multiple sets of stirring blades 6 promote the movement of various raw materials in the chamber of the housing 3 and promote the mixing of various raw materials.

[0022] like Figure 1 and Figure 3The sampling mechanism includes a lifting mechanism, a sealing mechanism, a delivery pump 7, a delivery hose 8, and a sampling tube 9. The delivery pump 7 is mounted on the bracket 1 and has a discharge pipe. The input end of the delivery pump 7 is connected to the sampling tube 9 through the delivery hose 8. The upper end of the sampling tube 9 is sealed, and the lower end is open. The sealing mechanism is used to seal the opening at the lower end of the sampling tube 9. The sampling tube 9 is located in the chamber of the housing 3. The sampling tube 9 is mounted on the lifting mechanism, which is used to lift and lower the sampling tube 9. When sampling the liquid in the chamber of the housing 3, the lifting mechanism is opened to lower the sampling tube 9 into the raw material liquid in the chamber of the housing 3. Then, the delivery pump 7 is opened to discharge the raw material in the chamber of the housing 3 sequentially through the sampling tube 9, the delivery hose 8, and the delivery pump 7 for collection. This facilitates the sampling of the raw material liquid in the chamber of the housing 3.

[0023] like Figure 3 The lifting mechanism includes a hydraulic cylinder A10 and a push rod 11. The hydraulic cylinder A10 is fixedly installed on the upper end of the housing 3. The output end of the hydraulic cylinder A10 is equipped with the push rod 11, which slides up and down on the housing 3. The upper end of the push rod 11 is connected to the output end of the hydraulic cylinder A10, and the sampling tube 9 is fixedly installed on the lower end of the push rod 11. When sampling the liquid in the chamber of the housing 3, the hydraulic cylinder A10 is opened. The hydraulic cylinder A10 adjusts the height of the sampling tube 9 through the push rod 11, thereby immersing the sampling tube 9 in the raw material liquid in the chamber of the housing 3, and then the raw material liquid can be sampled. Since the height of the sampling tube 9 can be adjusted, liquid can be sampled at any height in the chamber of the housing 3, which is convenient to use and highly practical.

[0024] like Figure 3 The sealing mechanism includes a hydraulic cylinder B12, a lifting rod 13, and a sealing plate 14. The hydraulic cylinder B12 is fixedly mounted on the upper end of the bracket 1. The lifting rod 13 is slidably mounted on the housing 3, with its lower end connected to the output end of the hydraulic cylinder B12. The sealing plate 14 is fixedly mounted on the upper end of the lifting rod 13, and is located below the sampling tube 9. When sampling the raw material liquid at a specified height within the chamber of the housing 3, the sampling tube 9 is first positioned above the liquid surface. Then, the hydraulic cylinder B12 is opened, causing the sealing plate 14 to rise via the lifting rod 13, thus sealing the sealing plate 14. The upper end of the 4 contacts the lower end of the sampling tube 9, and the opening at the lower end of the sampling tube 9 is sealed by the sealing plate 14. Then, the sampling tube 9 is lowered, and at the same time, the lifting rod 13 drives the sealing plate 14 to lower through the hydraulic cylinder B12. The lowering speed of the sealing plate 14 is the same as the lowering speed of the sampling tube 9, so that the sampling tube 9 is blocked by the sealing plate 14 when it descends in the raw material liquid, preventing liquid from other heights from entering the sampling tube 9, until the sampling tube 9 descends to the designated height in the liquid. Then, the sealing plate 14 is separated from the sampling tube 9, and the sampling tube 9 can take a sample; this improves the accuracy of sampling. A temperature gauge 16 is installed on the box body 3.

[0025] Example 2

[0026] Based on Example 1, a sealing pad 15 is provided at the upper end of the sealing plate 14; through the above arrangement, the sealing effect of the sealing plate 14 on the sampling tube 9 is improved.

[0027] The mixing plate 6, conveying pump 7, conveying hose 8, hydraulic cylinder A10, sealing plate 14, and sealing gasket 15 of the pharmaceutical intermediate production raw material mixing device of this utility model are all purchased from the market. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
