Abstract
Description
Technical Field
[0001] This utility model relates to the field of pharmaceutical processing technology, specifically to a device for separating original drug particles from powder. Background Technology
[0002] When pharmaceutical granules produced by pharmaceutical processing equipment are discharged from the equipment, a large amount of pharmaceutical powder is carried along with them. The pharmaceutical powder cannot be packaged into pharmaceutical bags for sale at the same time as the pharmaceuticals, so a separation device is needed to separate the pharmaceuticals and the powder.
[0003] In existing technologies, processed drug granules often contain a large amount of drug powder, which is separated from the drug granules by vibration. However, since the drug granules themselves are made by pressing drug powder, the vibration process may cause the powder to fall off the granules, resulting in a lighter overall weight of the drug granules and preventing them from achieving the intended therapeutic effect. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide a device for separating original drug particles and powders, so as to solve the technical problem that the separation of drug particles and powders by vibration may cause changes in drug quality.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for separating original drug granules and powders, comprising a body, a support frame fixedly connected inside the body, a motor disposed inside the support frame, a rotating shaft fixedly connected to the output end of the motor, a rotating frame fixedly connected to the bottom of the rotating shaft, a fixed ring fixedly connected to the bottom of the rotating frame, and the rotating frame and the fixed ring being connected by bolts, a separation ring fixedly connected to the bottom of the rotating frame, a powder sieving plate fixedly connected inside the body, the powder sieving plate being located at the bottom of the separation ring, and a fan fixedly connected to the top of the body.
[0006] By adopting the above technical solution, this utility model uses a conveying mechanism to deliver the drug particles and powders to be separated into the machine body, where they stop on the sieve plate. The motor will start, driving the rotating shaft to rotate. Through the rotating frame and the fixed ring, the separation ring is carried to rotate. The flow-limiting block will first contact the drug to limit the flow of the drug, allowing it to enter the separation ring. Since the cross-section of the separation ring is designed as a spiral, the drug gradually moves closer to the center position as the separation ring rotates. At the same time as the separation ring rotates, the fan located at the top of the machine body will continuously blow air into the machine body, causing the drug powder to leave the machine body through the powder outlet. After being carried to the center position of the sieve plate by the separation ring, the drug particles will fall into the drug outlet. Since the drug outlet is designed at an angle, the drug particles will leave the machine body along the drug outlet. Through the above structure, the technical problem that using vibration to separate drug particles and powders may cause changes in drug quality can be solved.
[0007] Furthermore, the separation ring has a spiral cross-section, and the separation ring can drive the drug inward through the spiral design. The separation ring and the fixed ring are fixedly connected by welding, and a flow limiting block is fixedly connected to one end of the separation ring.
[0008] By adopting the above technical solution, a flow-limiting block is fixedly connected to one end of the separation ring. The flow-limiting block located at the entrance of the separation ring will contact the medicine first, so that the medicine particles and powders remaining on the top of the sieve plate will reach the interior of the separation ring through the gap between the flow-limiting block and the sieve plate.
[0009] Furthermore, a medicine delivery port is fixedly connected to one side of the machine body, and a conveying mechanism is provided inside the medicine delivery port.
[0010] By adopting the above technical solution, the conveying mechanism first sends the drug particles and drug powder to be separated into the machine body through the drug delivery port on one side of the machine body. After the drug enters the machine body, it is sent to the powder screening plate by the conveying mechanism and stops.
[0011] Furthermore, a powder outlet is fixedly connected to the bottom of the machine body, and the outside of the powder outlet is connected to the powder storage mechanism. A medicine outlet is fixedly connected inside the powder sieve plate, and one end of the medicine outlet is connected to the outside of the machine body.
[0012] By adopting the above technical solution, the drug powder falls to the bottom of the machine body through the holes on the surface of the sieve plate and leaves the machine body from the powder outlet. The outside of the powder outlet is connected to an external storage device, so the drug powder can be collected for subsequent use. After being brought to the center of the sieve plate by the separation ring, the drug particles fall into the drug outlet. Since the drug outlet is designed at an angle, the drug particles will leave the machine body along the drug outlet and be transported to the next process by the subsequent conveying device.
[0013] In summary, this utility model has the following beneficial effects: The conveying mechanism delivers the drug particles and powders to be separated into the machine body, where they stop on the sieve plate. The motor then starts, driving the rotating shaft. Through the rotating frame and fixed ring, the separation ring is rotated. The flow-limiting block first contacts the drug, restricting its flow and allowing it to enter the separation ring. Because the separation ring has a spiral cross-section, the drug gradually moves towards the center as it rotates. Simultaneously, a fan at the top of the machine continuously blows air into the machine, causing the drug powder to exit through the powder outlet. The drug particles, after being carried to the center of the sieve plate by the separation ring, fall into the drug outlet. Since the drug outlet is angled, the drug particles exit the machine along the outlet. This structure solves the technical problem that using vibration to separate drug particles and powders may cause changes in drug quality. Attached Figure Description

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0021] The embodiments of this utility model will be described below based on its overall structure.
[0022] A device for separating original drug particles from powder, such as Figure 1-5As shown, it includes a body 1, a support frame 2 is fixedly connected inside the body 1, a motor 3 is installed inside the support frame 2, a rotating shaft 4 is fixedly connected to the output end of the motor 3, a rotating frame 5 is fixedly connected to the bottom of the rotating shaft 4, a fixed ring 6 is fixedly connected to the bottom of the rotating frame 5, and the rotating frame 5 and the fixed ring 6 are connected by bolts.
[0023] The machine 3 will start, driving the rotating shaft 4 to rotate, and at the same time driving the rotating frame 5 to rotate. The rotating frame 5 is fixed to the fixed ring 6 by bolts, so the fixed ring 6 will rotate synchronously.
[0024] In the example, a separation ring 7 is fixedly connected to the bottom of the rotating frame 5, and a powder sieving plate 8 is fixedly connected inside the body 1. The powder sieving plate 8 is located at the bottom of the separation ring 7. The bottom of the fixing ring 6 is fixed to the separation ring 7, and the top of the separation ring 7 is fixed to the rotating frame 5 by welding. Therefore, the separation ring 7 will also be rotated by the rotating frame 5. Since the cross-section of the separation ring 7 is a spiral design, when the separation ring 7 rotates on the top of the powder sieving plate 8, the inner wall of the separation ring 7 will continuously squeeze the medicine towards the center position, so that the medicine gradually moves inside the separation ring 7 and gradually approaches the center position.
[0025] Furthermore, a fan 12 is fixedly connected to the top of the machine body 1. While the separation ring 7 rotates, the fan 12 located at the top of the machine body 1 will continuously blow air into the machine body 1, so that the medicine particles can move on the surface of the sieve plate 8, and the medicine powder can fall to the bottom of the machine body 1 through the holes on the surface of the sieve plate 8.
[0026] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 The separation ring 7 has a spiral cross-section. The separation ring 7 can drive the medicine inward through its spiral design. The separation ring 7 is fixedly connected to the fixed ring 6 by welding. One end of the separation ring 7 is fixedly connected to the flow limiting block 9. The flow limiting block 9 located at the entrance of the separation ring 7 will contact the medicine first, so that the medicine particles and medicine powder remaining on the top of the sieve plate 8 can reach the interior of the separation ring 7 through the gap between the flow limiting block 9 and the sieve plate 8.
[0027] Please see Figure 1 and Figure 2 A drug delivery port 10 is fixedly connected to one side of the machine body 1. A conveying mechanism 14 is installed inside the drug delivery port 10. First, the conveying mechanism 14 will send the drug particles and drug powder to be separated into the machine body 1 through the drug delivery port 10 on one side of the machine body 1. After the drug enters the machine body 1, it will be sent by the conveying mechanism 14 to the powder screening plate 8 and stop.
[0028] Please see Figure 1 and Figure 2The bottom of the machine body 1 is fixedly connected to a powder outlet 13, which is connected to the powder storage mechanism. The inside of the powder sieve plate 8 is fixedly connected to a medicine outlet 11, one end of which is connected to the outside of the machine body 1. The medicine powder falls to the bottom of the machine body 1 through the holes on the surface of the powder sieve plate 8 and leaves the machine body 1 through the powder outlet 13. The outside of the powder outlet 13 is connected to an external storage device, so the medicine powder can be collected for subsequent use. After the medicine particles are brought to the center of the powder sieve plate 8 by the separation ring 7, they fall into the medicine outlet 11. Since the medicine outlet 11 is designed at an angle, the medicine particles will leave the machine body 1 along the medicine outlet 11 and be transported to the next process by the subsequent conveying device.
[0029] The working principle of this utility model is as follows: when in use, the power is turned on and the overall separation device will start working.
[0030] First, the conveying mechanism 14 will send the drug particles and drug powder that need to be separated into the inside of the machine body 1 through the drug delivery port 10 on one side of the machine body 1. After the drug enters the inside of the machine body 1, it will be sent by the conveying mechanism 14 to the powder screening plate 8 and stop.
[0031] At this time, motor 3 will start, driving shaft 4 to rotate, and at the same time driving rotating frame 5 to rotate. Rotating frame 5 is fixed to fixed ring 6 with bolts, so fixed ring 6 will rotate synchronously.
[0032] The bottom of the fixed ring 6 is fixed with the separation ring 7, and the top of the separation ring 7 is fixed to the rotating frame 5 by welding. Therefore, the separation ring 7 will also be rotated by the rotating frame 5. The flow limiting block 9 located at the entrance of the separation ring 7 will contact the medicine first, so that the medicine particles and medicine powder remaining on the top of the sieve plate 8 will reach the interior of the separation ring 7 through the gap between the flow limiting block 9 and the sieve plate 8.
[0033] Because the cross-section of the separating ring 7 is a spiral design, when the separating ring 7 rotates on the top of the powder sieve plate 8, the inner wall of the separating ring 7 will continuously squeeze the medicine towards the center, so that the medicine gradually moves inside the separating ring 7 and gradually approaches the center.
[0034] While the separating ring 7 is rotating, the fan 12 located at the top of the machine body 1 will continuously blow air into the machine body 1, so that the medicine particles can move on the surface of the sieve plate 8, and the medicine powder can fall through the holes on the surface of the sieve plate 8 to the bottom of the machine body 1, and leave the machine body 1 from the powder outlet 13. The powder outlet 13 is connected to an external storage device, so the medicine powder can be collected for subsequent use.
[0035] After the drug particles are brought to the center of the sieve plate 8 by the separation ring 7, they will fall into the drug outlet 11. Since the drug outlet 11 is designed to be inclined, the drug particles will leave the machine body 1 along the drug outlet 11 and be transported to the next process by the following conveying device.
[0036] The above structure can solve the technical problem that using vibration to separate drug particles and drug powder may cause changes in drug quality.
[0037] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
