Description

Technical Field

[0001] The utility model relates to the technical field of multi-stage filtering of medicinal powders, in particular to a multi-stage precision filtering device for medicinal powders used for capsule filling. Background Art

[0002] The multi-stage precision filtration equipment for drug powder for capsule filling plays a pivotal role in the production of pharmaceuticals, health products and nutritional supplements with its high efficiency and precision. The equipment uses a multi-stage filtration system to accurately remove impurities from drug powder to ensure that its quality and purity meet production requirements. However, the multi-stage filtration equipment currently on the market often faces challenges in filtration efficiency when using the top blowing method.

[0003] Although the top blowing method is simple, its principle determines that the wind force will gradually weaken during the propagation process. This phenomenon is particularly obvious in multi-stage filtering equipment. Since the wind force weakens with the increase of the propagation distance, the filter cartridge at the bottom can often only receive weaker wind force. This directly leads to a decrease in the flow rate of the powder passing through the bottom filter cartridge, thereby affecting the filtration efficiency of the entire equipment. The reduction in flow rate means that the amount of powder passing through the filter cartridge per unit time is reduced, which not only reduces production efficiency, but also may affect the filtration effect, making some smaller particles unable to be effectively intercepted.

[0004] In addition, reduced wind power will also have a negative impact on the cleaning and maintenance of the filter cartridge. Due to insufficient wind power, the residue on the filter cartridge may not be completely removed. Over time, these residues will gradually accumulate, causing the filter cartridge to be blocked, thereby affecting its filtering performance. This not only increases the maintenance cost of the equipment, but may also pose a potential threat to the quality and safety of the drug powder.

[0005] To address this problem, we propose an optimization solution: using side blowing instead of the traditional top blowing. By applying wind force on the side of the filter cartridge, the problem of wind force weakening during the propagation process can be effectively avoided, thereby ensuring that each level of the filter cartridge can receive sufficient wind force. This can not only increase the flow rate of the powder through the filter cartridge and improve the filtration efficiency, but also help improve the cleaning and maintenance of the filter cartridge and extend the service life of the equipment.

DETAILED DESCRIPTION

[0025] 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. Example

[0026] like Figures 1 to 4 As shown, a multi-stage precision filtering device for drug powder for capsule filling is designed to achieve efficient and accurate filtering effect. The device is mainly composed of a sealing cover 1, a connecting cylinder 2, a feeding pipe 3, a blowing device 4 and an upper cylinder 5.

[0027] First, the sealing cover 1 is firmly installed on the top of the connecting tube 2 to ensure the sealing inside the device. A feeding pipe 3 and a blowing device 4 are installed on the side wall of the connecting tube 2. The feeding pipe 3 is used to facilitate the injection of the capsule powder to be filtered into the device, while the blowing device 4 is responsible for blowing air into the connecting tube 2 to assist the filtering process.

[0028] The upper cylinder 5 located below the connecting cylinder 2 is cleverly installed with multiple filter cylinders through the mounting plate 9. These filter cylinders are, from top to bottom, the first filter cylinder 11, the second filter cylinder 13 and the third filter cylinder 15. The filter hole size of each filter cylinder is carefully designed to ensure the progressive filtering effect. At the same time, the through hole 10 on the mounting plate 9 is connected to the first filter cylinder 11, so that the wind blown by the blowing device 4 can smoothly enter the inside of the filter cylinder, causing vibration, thereby further improving the filtering efficiency.

[0029] In addition, a middle cylinder 6 is provided at the lower end of the upper cylinder 5, and a lateral blowing joint 7 is installed on the middle cylinder 6. The function of the lateral blowing joint 7 is to accelerate the vibration of the first filter cylinder 11, the second filter cylinder 13 and the third filter cylinder 15 by blowing, thereby further improving the filtering efficiency of the powder.

[0030] Below the middle cylinder 6 is the lower cylinder 8. A first discharge pipe 12 is provided at the lower end of the first filter cylinder 11. The discharge pipe passes through the second filter cylinder 13 and the lower cylinder 8 and is responsible for discharging the powder filtered by the first stage. Similarly, the second filter cylinder 13 and the third filter cylinder 15 are also provided with a second discharge pipe 14 and a third discharge pipe 16, respectively, for discharging the powder filtered by each. This design enables powders of different diameters to be discharged through different discharge pipes, thereby realizing the graded collection of powders.

[0031] It is worth mentioning that the first filter cartridge 11, the second filter cartridge 13 and the third filter cartridge 15 are connected to the discharge pipes thereof by suture connection, thereby ensuring the tightness and stability of the connection. At the same time, the discharge pipes are also sealed and fixed to the lower cylinder 8 to prevent leakage of the powder. Example

[0032] Based on the first embodiment, this embodiment further optimizes and improves the equipment.

[0033] First, in order to further improve the filtering efficiency and prevent the filter cartridge from being blocked, a push rod 17 is provided at the lower end of each of the first filter cartridge 11, the second filter cartridge 13 and the third filter cartridge 15. These push rods 17 are driven by hydraulic cylinders 18, and the hydraulic cylinders 18 are installed inside the sealing cover 19 located at the inner end of the lower cartridge 8. When the filter cartridge is blocked, the hydraulic cylinder 18 can push the push rod 17 through the telescopic end to lift the filter cartridge, thereby easily solving the blockage problem.

[0034] In addition, in order to ensure that the connection between the hydraulic cylinder 18 and the push rod 17 is stable and well sealed, we use a mechanical seal to connect. At the same time, the sealing cover 19 is also firmly fixed on the lower cylinder 8 through the side strips, ensuring the stability and reliability of the entire structure.

[0035] This improved design not only improves the filtration efficiency of the equipment, but also greatly reduces the maintenance cost and time cost caused by filter cartridge blockage. At the same time, the overall stability and reliability of the equipment are also significantly improved.

[0036] Filtration process: The capsule powder to be filtered is injected into the connecting tube 2 through the feeding pipe 3. At this time, the blowing device 4 starts to work and blows air into the connecting tube 2. The air passes through the through hole 10 on the mounting plate 9 and enters the first filter tube 11. The first filter tube 11 has relatively large filter holes and is mainly responsible for preliminary filtering of the powder to remove larger particles or impurities.

[0037] As the powder in the first filter cartridge 11 accumulates, the powder that has been initially filtered will naturally fall into the second filter cartridge 13. The filter holes of the second filter cartridge 13 are smaller than those of the first filter cartridge 11, and can further remove smaller particles and impurities. At the same time, the lateral blowing joint 7 starts to work, and by blowing the first filter cartridge 11, the second filter cartridge 13 and the third filter cartridge 15, vibration is induced, which helps the powder to pass through the filter holes better and prevents blockage.

[0038] Next, the medicine powder further filtered by the second filter cartridge 13 will fall into the third filter cartridge 15. The third filter cartridge 15 has the smallest filter holes and can achieve the finest filtering effect, ensuring that the medicine powder finally output meets the required particle size requirements.

[0039] During the filtration process, the discharge pipes under each filter cartridge play an important role. The first discharge pipe 12, the second discharge pipe 14 and the third discharge pipe 16 correspond to the first filter cartridge 11, the second filter cartridge 13 and the third filter cartridge 15 respectively. The powder after each stage of filtration will be discharged through the corresponding discharge pipe to achieve graded collection. This design allows powders of different particle sizes to be collected and processed separately, improving the accuracy and efficiency of filtration.

[0040] In addition, when the filter cartridge is clogged, the hydraulic cylinder 18 will push the push rod 17 through the telescopic end to lift the filter cartridge, thus easily solving the clogging problem. This automatic cleaning function ensures the continuous and stable operation of the equipment and reduces maintenance costs and time costs.

[0041] The multi-stage filtering structure of the filtration equipment achieves efficient and accurate filtering effects through step-by-step filtering and vibration-assisted filtering. At the same time, the hierarchical collection and automatic cleaning functions further improve the practicality and reliability of the equipment.

[0042] The standard parts used in the utility model can all be purchased from the market, and special-shaped parts can be customized according to the instructions and the drawings. The specific connection methods of each part adopt the conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt the conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology, which will not be described in detail here.

[0043] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
