Description

Technical Field

[0001] This utility model relates to the field of powder material conveying technology, and in particular to a bismuth potassium citrate material conveying device. Background Technology

[0002] In the pharmaceutical production of bismuth potassium citrate, spray drying is a crucial step in obtaining the finished powder. The dried powder needs to be transferred from the drying tower outlet to a subsequent wet mixer for homogenization and other processing; this process typically occurs during the inner packaging stage. Currently, the industry's commonly used material transfer method still relies on traditional manual operation: the dried powder first falls into an open receiving hopper or transfer container, and then operators manually move the hopper to the wet mixer station to pour and add the powder.

[0003] Currently, conventional production processes still have the following problems: 1. The entire transfer process relies entirely on manual intervention, which is not only labor-intensive and consumes human resources, but also time-consuming in the handling and dumping stages. It is difficult to efficiently connect with the front-end and back-end automated production equipment, becoming a bottleneck that restricts the improvement of overall production efficiency and capacity. 2. Bismuth potassium citrate is a fine powder that easily generates dust during manual dumping. This not only results in the loss of valuable materials, but more seriously, the diffused dust contaminates the clean environment of the inner packaging area, directly violating the stringent cleanliness requirements of Good Manufacturing Practices (GMP) for pharmaceutical production environments. Furthermore, the floating dust poses a potential hazard to the respiratory health of on-site personnel, indicating an occupational health and safety risk. 3. Open-top operations expose materials to the external environment during transfer, increasing the likelihood of contamination by foreign objects or exposure to ambient humidity, which threatens the uniformity and stability of the final drug quality. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a bismuth potassium citrate material conveying device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bismuth potassium citrate material conveying device, including a base, a raised platform fixedly installed on the upper end of the base, a side platform first assembled on the upper end of the raised platform, a support sleeve first fixedly installed on one side of the side platform first through a bracket, and a material cylinder first fixedly sleeved inside the support sleeve first. The inner side of the material cylinder is slidably fitted with a frame, and several support plates are fixedly distributed on the inner wall of the material cylinder. The lower end of the frame is attached to the surface of the support plate. The inner side of the frame is provided with an annular groove, and a filter plate is slidably attached to the inner side of the annular groove. Several springs are fixedly distributed on the outer wall of the filter plate, and the end of any one of the springs away from the filter plate is fixedly installed inside the annular groove. The upper end of the material cylinder is fixedly covered by a cylinder cover, and a feed port is fixedly inserted through the center of the cylinder cover.

[0006] Preferably, the lower end of the filter plate is equipped with a mounting plate, and the lower end of the mounting plate is fixed with a motor by a bracket. The motor has a drive shaft inside, and an eccentric block is fixedly installed at the end of the shaft.

[0007] Preferably, threaded sleeves are fixed through both sides of the frame, and threaded knobs are installed inside the threads of the threaded sleeves. Threaded grooves are opened on the inner wall of the material cylinder, and the end of the threaded knob is threadedly installed with the inner wall surface of the threaded groove.

[0008] Preferably, a second side platform is fixedly installed at the end of the raised platform away from the first side platform, and a second support sleeve is fixedly installed on the surface of the second side platform, with a second material cylinder fixedly sleeved inside the second support sleeve.

[0009] Preferably, a cover is fixed to the upper end of the second material cylinder, and a vacuum pump is mounted on the upper end of the cover via a bracket, with the discharge end of the vacuum pump embedded through the center of the cover.

[0010] Preferably, the lower end of the material cylinder is connected to a flange at the discharge position of the material cylinder, and the end of the material cylinder away from the material cylinder is connected to the inlet flange of the vacuum pump.

[0011] Preferably, a wet mixer is fixedly installed on the upper end of the base, and a feeding pipe is connected to the feed end flange of the wet mixer. The upper end of the feeding pipe is connected to the discharge position flange of the second material cylinder.

[0012] The design scheme proposed in this utility model has the following beneficial effects in application: 1. This solution uses a completely closed pipeline system for material transfer. The entire process of powder from entering the feed cylinder to finally being sent to the wet mixer is completed in a closed space, completely eliminating the possibility of dust leakage. This not only greatly reduces the risk of material being contaminated by the environment, but also ensures the stability of product quality. 2. This solution automatically draws the powder from cylinder one into cylinder two through the suction pipe using a vacuum pump, and then sends it into the wet mixer through the feeding pipe. This replaces the original heavy and time-consuming manual handling and dumping process, freeing operators from repetitive physical labor. 3. This solution uses a filter plate inside the material cylinder to effectively intercept large particles or potential foreign objects, preventing them from entering the conveying pipeline and causing blockages or affecting the subsequent mixing quality. Driven by a motor, the filter plate can generate slight vibrations. This dynamic filtration method can not only prevent the filter holes from being blocked by fine powder and maintain high filtration efficiency, but also loosen the powder and assist in feeding, ensuring that the powder can be smoothly sucked and transferred.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Example 1 Reference Figures 1-4 A bismuth potassium citrate material conveying device includes a base 1, a raised platform 11 fixedly installed on the upper end of the base 1, a side platform 12 assembled on the upper end of the raised platform 11, a support sleeve 13 fixedly installed on one side of the side platform 12 by a bracket, and a material cylinder 14 fixedly sleeved inside the support sleeve 13. The side platform 12, together with the support sleeve 13, can stably raise and place the material cylinder 14. The inner wall of the material cylinder 14 is fitted with a frame 15. Several support plates 17 are fixedly distributed on the inner wall of the material cylinder 14. The lower end of the frame 15 is attached to the surface of the support plate 17. The inner wall of the frame 15 is provided with an annular groove, and a filter plate 16 is slidably attached to the inner wall of the annular groove. Several springs 18 are fixedly distributed on the outer wall of the filter plate 16. The end of any spring 18 away from the filter plate 16 is fixedly installed inside the annular groove. After the material powder enters the material cylinder 14, it will be filtered by the filter plate 16. Large particles of material powder can be isolated to avoid affecting the vacuum pumping process. The filter plate 16 can slide in all directions based on the annular groove of the frame 15. The springs 18 distributed at multiple points can ensure that the filter plate 16 returns to its original position after moving. The upper end of the material cylinder 14 is fixedly covered with a cylinder cover 19, and a feed port 110 is fixedly fixed through the center of the cylinder cover 19. The cylinder cover 19 and the feed port 110 can seal the feeding of the spray-dried bismuth potassium citrate powder. Compared with the traditional open material cylinder 14, it can ensure that the powder is not affected by external environmental impurities and dust.

[0017] The filter plate 16 is equipped with a mounting plate 2 at its lower end. The lower end of the mounting plate 2 is fixed with a motor 21 by a bracket. The motor 21 has a drive shaft inside, and an eccentric block 22 is fixedly installed at the end of the shaft. In order to ensure that the filter plate 16 can produce a vibrating screening effect, the power supply of the motor 21 is turned on, so that the motor 21 can drive the eccentric block 22 to rotate through the shaft, producing a centrifugal vibration effect. The motor 21 is a dustproof model, and dustproof rings are added to each connection point for auxiliary dustproof protection.

[0018] Both sides of the frame 15 are fixed with threaded sleeves 201. The threaded sleeves 201 are threaded with threaded knobs 202. The inner wall of the material cylinder 14 is provided with threaded grooves. The end of the threaded knob 202 is threadedly installed with the inner wall of the threaded groove. The frame 15 can be erected in the material cylinder 14 based on the support plate 17. Then, the threaded knob 202 can be threadedly moved relative to the threaded sleeves 201 to be threadedly installed with the corresponding threaded grooves, so that the frame 15 can be stably installed based on the material cylinder 14.

[0019] Among them, the raised platform 11 is fixedly installed with a side platform 2 3 at the end away from the side platform 12. The surface of the side platform 2 3 is fixedly installed with a support sleeve 2 31. The inside of the support sleeve 2 31 is fixedly sleeved with a material cylinder 2 32. The material cylinder 2 32 is a collection container after vacuum extraction. The height and position of the material cylinder 2 32 can be ensured by the side platform 2 3 and the support sleeve 2 31.

[0020] Among them, the upper end of the material cylinder 2 32 is fixed with the cylinder cover 2 33, and the upper end of the cylinder cover 2 33 is equipped with a vacuum pump 34 through a bracket. The discharge end of the vacuum pump 34 is embedded through the center of the cylinder cover 2 33. After the vacuum pump 34 is started, it can draw the powder in the material cylinder 1 14 and send it into the interior of the material cylinder 2 32.

[0021] The lower end of the material cylinder 14 is connected to the discharge flange with a material extraction pipe 35. The end of the material extraction pipe 35 away from the material cylinder 14 is connected to the feed flange of the vacuum pump 34. The material extraction pipe 35 can ensure the sealing effect of the path during the vacuum extraction process.

[0022] The base 1 has a wet mixer 36 fixedly installed on its upper end. The feed end flange of the wet mixer 36 is connected to a feed pipe 37. The upper end of the feed pipe 37 is connected to the discharge position flange of the material cylinder 32. The feed pipe 37 can ensure the sealing and stability of the feed path when the powder is fed into the wet mixer 36 for processing.

[0023] In practice After the spray drying process is completed, the resulting bismuth potassium citrate powder first enters the system through the feed inlet 110. The powder falls into a sealed receiving unit consisting of a material cylinder 14, a cylinder cover 19, and the feed inlet 110. This design completely replaces the traditional open receiving hopper, preventing impurities and dust from contaminating the powder from the external environment. It also prevents the powder from escaping into the clean production environment during the receiving stage. The powder entering the material cylinder 14 falls onto the filter plate 16, which is placed in an annular groove inside a frame 15. The key feature is that multiple springs 18 distributed on its outer ring wall achieve elastic connection with the frame 15, which gives the filter plate 16 a certain amount of mobility. The qualified fine powder in the powder falls through the mesh of the filter plate 16 under the action of gravity, while large particles that may be formed due to moisture or static electricity are intercepted on the filter plate 16. This preliminary screening process effectively prevents the blockage that may occur in the subsequent conveying pipeline and ensures the continuity of conveying. The clean fine powder filtered by the frame 15 and the filter plate 16 is finally temporarily stored at the bottom of the material cylinder 14, waiting to be conveyed. To ensure screening efficiency and prevent fine powder from bridging or clogging the mesh on the filter plate 16, the system integrates a specialized vibration-assisted mechanism. The core components of this function are the motor 21 installed directly below the filter plate 16 and the eccentric block 22 fixed to the end of its rotating shaft. When the system receives a start command or runs according to a preset program, the motor 21 is powered on and starts, driving the eccentric block 22 to rotate at high speed. Due to the uneven mass distribution of the eccentric block 22, periodic centrifugal force is generated during rotation, thereby triggering high-frequency, low-amplitude mechanical vibration. This vibration is directly transmitted to the filter plate 16 above through the mounting plate 2. Under this vibration, the powder retained on the filter plate 16 is thrown up and loosened. On the one hand, this promotes the faster passage of qualified fine powder through the mesh, improving screening efficiency. On the other hand, it also effectively breaks up some slightly agglomerated powder lumps and prevents the filter holes from clogging. At the same time, the frame 15 is reliably fixed to the material cylinder 14 through the threaded sleeves 201 on both sides and the threaded knobs 202 screwed into the threaded grooves on the inner wall of the material cylinder 14. This ensures that the vibration energy mainly acts on the screening process and does not cause the entire filter assembly to loosen or shift, creating ideal material conditions for subsequent stable and smooth negative pressure suction. When the wet mixer 36 needs to be fed, the core conveying component of the system is activated, and the power source vacuum pump 34 starts working, generating a strong negative pressure inside the directly connected material cylinder 32. This negative pressure is transmitted to the bottom space of the material cylinder 14 through the extraction pipe 35, thus creating a significant pressure difference between the inside of the material cylinder 14 and the inside of the material cylinder 32. Under the action of the pressure difference, the bismuth potassium citrate powder temporarily stored at the bottom of the material cylinder 14 is successfully sucked up, enters the extraction pipe 35, and is smoothly conveyed to the vacuum pump 34 through this closed pipe in the form of pneumatic conveying. Finally, it enters the material cylinder 32 for temporary storage or direct gas-powder separation, completing the process of feeding the material into the material cylinder 32. After conveying material 2, the next stage is to feed the powder into the wet mixer 36. The discharge port at the bottom of the second material cylinder 32 is connected to the inlet of the wet mixer 36 through the feeding pipe 37 with a flange seal. The separated pure powder is safely and cleanly discharged into the wet mixer 36 through the feeding pipe 37 under the action of gravity or, if necessary, a small amount of positive pressure, for subsequent wet mixing. The entire conveying and unloading process from the first material cylinder 14 to the wet mixer 36 is carried out in a completely closed pipeline system, including the extraction pipe 35 and the feeding pipe 37, realizing point-to-point automated dust-free transfer of materials and completely eliminating the risk of dust exposure and human cross-contamination.
