Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical processing equipment technology, specifically to a device for separating pharmaceutical particles from pharmaceutical powder. Background Technology

[0002] Separating granular and powdered drugs is crucial in pharmaceutical production and processing. Granular and powdered drugs differ in physical properties, such as particle size, flowability, and bulk density, which directly affect subsequent processing and efficacy. If they are mixed without separation, uneven filling may occur during packaging, affecting the accuracy of drug dosage; during formulation, uneven mixing may lead to inconsistent distribution of drug components, thus affecting the stability and reliability of drug efficacy. Therefore, the scientific separation of granular and powdered drugs is a vital step in ensuring drug quality, improving production efficiency, and guaranteeing medication safety.

[0003] In traditional separation methods, pharmaceutical raw materials tend to roll on the sieve during screening, causing the drugs to accumulate. Furthermore, small-sized drug powders cannot fully pass through the sieve holes, resulting in incomplete separation. This leads to a large amount of powder mixed in the product, affecting the purity of the drug and subsequent processing.

[0004] To address the aforementioned issues, we propose a device for separating pharmaceutical particles from pharmaceutical powder. Utility Model Content

[0005] The purpose of this invention is to provide a device for separating pharmaceutical granules and pharmaceutical powders to address the aforementioned shortcomings in the technology.

[0008] Preferably, the bottom outer wall of the exhaust sleeve is fixedly provided with an annular retaining tooth, and the top inner wall of the storage sleeve is fixedly provided with a rotating retaining block, which engages with the inner wall of the annular retaining tooth.

[0009] Preferably, a second bearing is fixedly provided on the inner wall of one end of the rotary screen cylinder, and an upwardly curved feed pipe is fixedly provided on the inner wall of the second bearing. A feed hopper is fixedly provided at the top end of the feed pipe.

[0010] Preferably, a fixing plate is fixedly provided on one side of the outer wall of the feed hopper, and the outer wall of the fixing plate is fixedly connected to the top outer wall of the powder separation box.

[0011] Preferably, the outer wall of the rotating screen cylinder away from the feed pipe is equipped with an outwardly expanding discharge port.

[0012] Preferably, the bottom two outer walls of the powder separation box are fixed with vertically downward support legs.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] The electric motor drives the rotating screen cylinder to rotate, and the conveying auger rotates accordingly to transport the medicine. This allows the small-sized medicine powder to pass through the screen holes and enter the powder separation box. The raw materials continuously tumble, collide, and rise into the air, which greatly improves the separation effect of particles and powder and effectively avoids the problem of incomplete separation that may occur in traditional separation methods.

[0015] At the same time, the airflow generated by the rotation of the exhaust fan is drawn in from both ends of the rotating sieve cylinder, further promoting the powder to enter the powder separation box through the sieve holes, and then being drawn into the storage sleeve through the exhaust sleeve. The drug powder is collected by the filter bag, which can fully separate the powder from the particles. Attached Figure Description

[0031] Example 3

[0032] Based on Embodiment 1, a second bearing 22 is fixedly installed on the inner wall of one end of the rotating screen cylinder 4. The upwardly curved feed pipe 21 is installed on the inner wall of the second bearing 22, so that the feed pipe 21 can rotate relative to the rotating screen cylinder 4. A feed hopper 23 is fixedly installed at the top end of the feed pipe 21. A fixing plate 24 is fixedly installed on the outer wall of one side of the feed hopper 23. The outer wall of the fixing plate 24 is fixedly connected to the top outer wall of the powder separation box 1 to fix the feed hopper 23. An outwardly expanding discharge port 25 is installed on the outer wall of the rotating screen cylinder 4 away from the feed pipe 21 for discharging the separated drug particles. Vertically downward supporting legs 26 are fixedly installed on the bottom two outer walls of the powder separation box 1 for supporting this utility model.

[0033] Working principle of this utility model:

[0034] Refer to the instruction manual appendix Figure 1-6 When using this utility model, the raw materials of medicine are first poured into the feed hopper 23. The raw materials of medicine enter the rotary screen cylinder 4 along the upward curved feed pipe 21. At this time, the motor 8 is started. The motor 8 drives the drive pulley 9 to rotate. The power is transmitted to the driven pulley 6 through the belt 10, which in turn drives the rotary screen cylinder 4 to rotate around its own axis. The conveying auger 20 inside the rotary screen cylinder 4 rotates together with the rotary screen cylinder 4. During the rotation, the conveying auger 20 conveys the raw materials of medicine towards the discharge port 25 at the end of the rotary screen cylinder 4 away from the feed pipe 21.

[0035] During the conveying process, as the rotating screen cylinder 4 rotates continuously, the pharmaceutical raw materials are subjected to centrifugal force. The smaller particle size of the pharmaceutical powder can enter the powder separation box 1 through the sieve holes 5 evenly distributed on the outer wall of the rotating screen cylinder 4. The pharmaceutical powder is constantly tumbling, colliding, and rising into the air, which can effectively separate the particles from the powder. At the same time, the exhaust fan 19 on the inner wall of the bottom of the storage sleeve 13 is activated. The exhaust fan 19 rotates to generate airflow. The airflow is drawn in from both ends of the rotating screen cylinder 4, which in turn carries the powder into the powder separation box 1 through the sieve holes 5. The airflow draws the pharmaceutical powder in the powder separation box 1 into the storage sleeve 13 through the exhaust sleeve 11. The filter bag 16 in the storage sleeve 13 can filter and collect the pharmaceutical powder, while the gas is discharged through the filter bag 16. With the continuous conveying of the conveying auger 20, the pharmaceutical particles are finally discharged from the discharge port 25, thus achieving effective separation of pharmaceutical particles and pharmaceutical powder.

[0036] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
