Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical mixing, in particular to a universal mixing unit for pharmaceutical use. Background Art

[0002] As the core equipment in the pharmaceutical industry, the pharmaceutical universal mixer undertakes multiple tasks such as mixing, stirring, and grinding, and plays an irreplaceable role in ensuring the quality of drugs and production efficiency. However, in actual use, its cleaning problem has become a key link that we need to explore in depth.

[0003] In the pharmaceutical process, the mixing unit is responsible for accurately mixing various pharmaceutical raw materials to produce drugs that meet the standards. However, given the diversity and complexity of pharmaceutical raw materials, including possible toxic ingredients, the mixing unit must be deeply cleaned after production to ensure the safety and purity of the drugs.

[0004] However, existing cleaning mechanisms may have certain limitations when dealing with the cleaning of mixing units. For example, for some viscous or difficult-to-dissolve raw materials, existing cleaning methods may not be able to completely remove their residues, which increases the risk of cross-contamination and poses a potential threat to the quality of the next batch of drugs. In addition, the cleaning process often takes a long time, which not only increases production costs, but may also affect the normal operation efficiency of the production line.

[0005] In addition, we also need to pay attention to the energy consumption during the cleaning process. Efficient cleaning methods should be able to reduce energy consumption to achieve green and sustainable production.

[0006] At the same time, the design of the cleaning mechanism of the mixing unit should also take into account the humanized operation requirements. Complex cleaning steps and operations may increase the difficulty of operation, and even lead to poor cleaning effect due to improper operation. Therefore, optimizing the design of the cleaning mechanism, simplifying the operation steps, and reducing the difficulty of operation are of great significance to improving the cleaning effect and ensuring the quality of drugs.

[0027] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0028] like Figure 1 - Figure 5As shown, a universal pharmaceutical mixing unit integrates multiple key components such as a support base 1, a mixing barrel 2, a transmission device 3, a driving device 4, a discharge pipe 5, a spiral scraper 6, and a mixing bin 7. This mixing unit achieves efficient mixing and uniform stirring of pharmaceutical raw materials through a carefully designed structure, bringing great convenience to the pharmaceutical industry.

[0029] The support base 1 serves as a stable foundation for the entire unit and bears the weight of the mixing barrel 2 and the driving device 4. The mixing barrel 2 is the main part of the mixing, and its internal space is used to accommodate pharmaceutical raw materials, and is driven by the driving device 4 to rotate. The driving device 4 provides a stable rotational power for the mixing barrel 2 through a power source such as a motor.

[0030] The transmission device 3 is installed on the side wall of the mixing barrel 2 and connected to the driving device 4, and is responsible for transmitting the power of the driving device 4 to the mixing barrel 2. The spiral scraper 6 is placed inside the mixing barrel 2 and connected to the transmission device 3. When the mixing barrel 2 rotates, the spiral scraper 6 will also rotate to stir and mix the pharmaceutical raw materials.

[0031] The mixing bin 7 is provided at the upper end of the mixing barrel 2 for injecting pharmaceutical raw materials. The spiral scraper 6 is driven by the driving device 4 to rotate inside the mixing barrel 2 to fully stir and mix the pharmaceutical raw materials. At the same time, the scraper portion of the spiral scraper 6 can effectively scrape off the pharmaceutical raw material agglomerates on the inner wall of the mixing bin 7 to ensure uniform mixing of the raw materials.

[0032] At the bottom of the mixing barrel 2, a discharge pipe 5 is provided for discharging the mixed pharmaceutical raw material mixture. The design of the discharge pipe 5 takes into account the discharge efficiency and cleaning convenience to ensure that the mixture can be discharged smoothly.

[0033] In addition, in order to enhance the functionality and cleaning convenience of the mixing unit, the unit is also equipped with some auxiliary devices. For example, a sealing cover 8 is connected to the top of the mixing barrel 2 to prevent the raw materials from leaking during the mixing process. A plurality of connection frames 10 are provided on the sealing cover 8, and an elastic strip 11 is installed under each connection frame 10. A cleaning brush 12 for cleaning the spiral scraper 6 is installed at the lower end of the elastic strip 11. These cleaning brushes 12 can effectively remove the residue on the surface of the spiral scraper 6 when it rotates to keep it clean.

[0034] In order to control the contact degree between the cleaning brush 12 and the spiral scraper 6, the unit is also equipped with a U-shaped frame 9, on which a plurality of squeezing rods 13 are installed. These squeezing rods 13 are arranged opposite to the elastic strip 11, and the elastic strip 11 can be forced to deform by rotating the squeezing rods 13, so that the cleaning brush 12 is more closely in contact with the spiral scraper 6, achieving more efficient cleaning.

[0035] At the lower end of the discharge pipe 5, a servo motor 14 and a sewage pipe 15 are also connected. A rotating rod with a brush is provided inside the sewage pipe 15, and the rotating rod passes through the plug of the sewage pipe 15 and is connected to the servo motor 14. When the servo motor 14 is started, the rotating rod with the brush will rotate in the sewage pipe 15, thereby accelerating the discharge speed of the pharmaceutical raw material mixture. At the same time, by injecting clean water into the discharge pipe 5 and the sewage pipe 15, and stirring with the rotating rod with a brush and the servo motor 14, the inside of the sewage pipe 15 can be effectively cleaned and kept unobstructed.

[0036] In addition, the mixing barrel 2 and the driving device 4 are fixed to the support base 1 by bolts to ensure the stability and reliability of the entire unit structure. The support base 1 is also provided with mounting holes to facilitate users to install and adjust according to their needs. The transmission device 3 adopts a belt transmission structure, which has the characteristics of high transmission efficiency and stable operation.

[0037] The sealing cover 8 is fixed to the mixing barrel 2 by a lock to ensure its sealing during the mixing process. The connecting frame 10 and the sealing cover 8 are fixed by bolts, and a sealing strip is provided at the connection to enhance its sealing effect. The elastic strip 11 is fixed to the connecting frame 10 by welding to ensure the firmness of its structure. The elastic strip 11 is made of elastic metal and has good elasticity and durability.

[0038] Under normal working conditions, the elastic strip 11 is wavy to meet different cleaning needs. When the cleaning effect needs to be enhanced, the elastic strip 11 can be deformed into an arc by rotating the squeezing rod 13, so that the cleaning brush 12 can be more closely contacted with the spiral scraper 6. This design allows the cleaning brush 12 to be adjusted as needed to achieve a more efficient cleaning effect.

[0039] Working process: The working process of the pharmaceutical mixer begins with injecting the pharmaceutical raw materials into the mixing barrel 2 through the mixing bin 7. Subsequently, the driving device 4 is started, and the power is transmitted to the mixing barrel 2 through the transmission device 3, so that it starts to rotate. During the rotation of the mixing barrel 2, the spiral scraper 6 also rotates to stir and mix the pharmaceutical raw materials. The scraper part of the spiral scraper 6 can effectively scrape off the lumps of pharmaceutical raw materials on the inner wall of the mixing bin 7 to ensure uniform mixing of the raw materials.

[0040] During the mixing process, the user can adjust the rotation speed of the spiral scraper 6 and the rotation speed of the mixing barrel 2 as needed to achieve the best mixing effect. At the same time, the sealing cover 8 ensures that the raw materials will not leak during the mixing process, keeping the working environment clean and safe.

[0041] When the mixing is completed, the mixed pharmaceutical raw material mixture can be discharged smoothly by controlling the switch of the discharge pipe 5. At this time, the user can continue to add new pharmaceutical raw materials for the next round of mixing according to production needs; cleaning: The cleaning process of the pharmaceutical mixer is also important to ensure the hygiene and performance of the equipment when it is used next time. The cleaning process mainly includes cleaning the mixing barrel 2, the spiral scraper 6, the discharge pipe 5 and the sewage pipe 15.

[0042] Turn off all power supplies to ensure that the equipment is in a safe state. Then, turn on the switch of the discharge pipe 5 to discharge the residual pharmaceutical raw material mixture in the mixing barrel 2. Next, use a cleaning tool or a high-pressure water gun to rinse the inside of the mixing barrel 2 to remove the residue.

[0043] For cleaning of the spiral scraper 6, the elastic strip 11 can be deformed by rotating the extrusion rod 13, so that the cleaning brush 12 can more closely contact the surface of the spiral scraper 6. Then, the driving device 4 is started to rotate the spiral scraper 6, and the cleaning brush 12 will effectively remove the residue on its surface.

[0044] The discharge pipe 5 and the sewage pipe 15 can be cleaned by injecting clean water therein and stirring them with a rotating rod with a brush and a servo motor 14 to remove the residues and dirt inside.

[0045] Finally, check that all parts are clean and there is no residue left, then dry or wipe the equipment and prepare for the next use; through regular cleaning and maintenance, the pharmaceutical mixer can maintain good working condition and performance, ensuring the mixing quality and production efficiency of pharmaceutical raw materials.
