Description

Technical Field

[0001] This utility model relates to the technical field of pharmaceutical powder processing, and in particular to a pharmaceutical powder drying device. Background Technology

[0002] A pharmaceutical powder drying device is a specialized piece of equipment used in pharmaceutical production to dehydrate and dry pharmaceutical powders. It is mainly used to remove moisture from pharmaceutical powders to ensure the stability of the drugs prepared subsequently, extend their shelf life, and improve their storage and transportation performance.

[0003] Microwave dryers utilize the principle of microwave radiation to directly heat and evaporate the moisture in medicinal powders, thereby achieving rapid drying. During the drying process, the medicinal powder is placed onto a conveyor belt through a hopper, and then the first motor is started to drive the rotating shaft, which in turn drives the conveyor belt to transport the medicinal powder into the microwave dryer. The microwave dryer is then started to perform drying and heating treatment.

[0004] Because the powder tends to accumulate and clump when it falls onto the conveyor belt, the rate of moisture evaporation is different for the powder surface far from the conveyor belt and the powder near the conveyor belt during drying. The moisture on the top layer of powder far from the conveyor belt may evaporate quickly under the action of microwaves, while the moisture on the bottom layer of powder close to the conveyor belt and accumulated there evaporates more slowly. This may result in uneven drying of the powder, affecting the drying quality and efficiency of the product.

[0005] Therefore, a new solution is needed to address the defects and shortcomings of the existing technology. Utility Model Content

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] [First Embodiment] like Figure 1-4The image shown is a powder drying device provided in the first embodiment of this utility model, such as... Figure 1 As shown, the device includes a microwave dryer 1. A circular shaft 3 is symmetrically mounted on the inner wall of the microwave dryer 1. A conveyor belt 4 is wound around the outer edge of the circular shaft 3. A first motor 5 is fixedly mounted on one side of the microwave dryer 1, and the output end of the first motor 5 is fixedly connected to one of the circular shafts 3. A feeding hopper 6 is provided on one side of the microwave dryer 1. An auxiliary device 2 is provided on the inner wall of the microwave dryer 1, located on one side of the conveyor belt 4. The output power of the first motor 5 drives the circular shaft 3 fixedly connected to its output end to rotate. The rotation of the circular shaft 3 drives the conveyor belt 4 to move, thereby moving the powder on the conveyor belt 4. The improvement of this embodiment compared to the prior art is that the auxiliary device 2 can turn over the powder placed on the conveyor belt 4, and at the same time, the conveyor belt 4 can tap and vibrate the powder, turning and stirring the accumulated powder. This effectively achieves a uniform and stable drying effect between the upper and lower layers of powder. At the same time, the tapping and vibration treatment of the powder reduces the possibility of accumulation or clumping during the drying process, improves the drying quality and efficiency of the powder, accelerates the evaporation of moisture, enhances the performance of the microwave dryer, optimizes energy utilization, and reduces drying time.

[0025] like Figure 2-4 As shown, the auxiliary device 2 in this embodiment includes several sprocket stirring rods 21 rotatably mounted on the inner wall of the microwave dryer 1. A second motor 22 is fixedly mounted on one side of the microwave dryer 1, and its output end is fixedly connected to one of the sprocket stirring rods 21. A first chain 23 is wound around the outer edge of two adjacent sprocket stirring rods 21. A striking mechanism 25 is provided between one of the sprocket stirring rods 21 and the inner wall of the microwave dryer 1. The striking mechanism 25 can strike and vibrate the powder during the drying process. The output power of the second motor 22 drives one of the sprocket stirring rods 21 to rotate, and through the first chain 23, drives the remaining sprocket stirring rods 21 to rotate and stir synchronously on the conveyor belt, stirring up the accumulated powder. At the same time, it drives the striking mechanism 25 to strike and vibrate one side of the conveyor belt, thereby preventing the powder from accumulating or clumping during the drying process, improving the drying quality and efficiency of the powder, accelerating the evaporation of moisture, improving the performance of the microwave dryer, optimizing energy utilization, and reducing drying time. Based on this, several stirring teeth on the outer edge of the sprocket stirring rod 21 are arranged in an axially staggered manner to improve the uniformity of stirring and turning the medicine. This enables uniform stirring of the medicine powder at various positions on the conveyor belt, avoids the accumulation of medicine powder, and improves drying efficiency and effect.

[0026] like Figure 3-4As shown, the striking mechanism 25 in this embodiment includes an arc-shaped gear rod 252 and a circular gear rod 253 rotatably mounted on one side of the microwave dryer 1. A circular gear rod 253 is rotatably mounted on the inner wall of the microwave dryer 1 and inside the conveyor belt 4, with the ends of the circular gear rod 253 meshing with those of the arc-shaped gear rod 252. A second chain 251 is wound around one of the sprocket stirring rods 21 and the outer edge of the arc-shaped gear rod 252. Several striking rods 255 are fixedly mounted on the axial outer edge of the circular gear rod 253. A second motor 22 outputs power to drive one of the sprocket stirring rods 21. While rotating, the second chain 251 drives the arc-shaped gear rod 252 to rotate synchronously, which in turn drives the circular gear rod 253 meshing with the arc-shaped gear rod 252 to rotate synchronously. This, in turn, drives several striking rods 255 fixed to the circular gear rod 253 to rotate synchronously. The striking rods 255 then strike the conveyor belt 4 to achieve a striking effect on the powder on the conveyor belt. This reduces the possibility of powder accumulation or clumping during the drying process, improves the drying quality and efficiency of the powder, accelerates moisture evaporation, enhances the performance of the microwave dryer, optimizes energy utilization, and reduces drying time.

[0027] To achieve reset after impact, an elastic reset element 254 is sleeved on the outer edge of the circular gear rod 253, and its two ends are fixedly connected to the circular gear rod 253 and the microwave dryer 1, respectively. The elastic reset element 254 can be a torsion spring commonly used in the mechanical field. Before the impact occurs, the arc-shaped gear rod 252 meshes with the circular gear rod 253, causing the circular gear rod 253 to rotate within a preset angle range. At this time, the elastic reset element 254 is deformed and compressed. After the impact is completed, the arc-shaped gear rod 252 disengages from the circular gear rod 253, and the elastic reset element 254 can drive the circular gear rod 253 back to its initial position under the action of elastic restoring force. Thus, the impact process on the powder on the conveyor belt 4 is realized through the reciprocating motion.

[0028] To ensure that the end of the striking rod 255 rotates within a preset range, thereby achieving the effect of striking the conveyor belt 4 without affecting the normal conveying process of the conveyor belt 4 due to excessive rotation angle, the entire outer edge of the end of the circular gear rod 253 is uniformly provided with meshing teeth, and the outer edge of the end of the arc-shaped gear rod 252 is also uniformly provided with meshing teeth. This allows for meshing transmission between the arc-shaped gear rod 252 and the circular gear rod 253 within a preset range, and disengagement after exceeding this meshing range to facilitate the reset process.

[0029] As a further preferred embodiment, a protective block 256 is fixedly installed on the outer end of the striking rod 255. The protective block 256 is spherical and made of rubber, which can protect the outer edge of the striking rod 255, reduce the impact wear between it and the conveyor belt 4, and improve its service life.

[0030] In addition, a reinforcing rod 257 is fixedly installed at the connection position between the striking rod 255 and the circular gear rod 253 to further increase the connection strength between the striking rod 255 and the circular gear rod 253, ensuring synchronous and stable rotation.

[0031] like Figure 2 As shown, a protective cover 24 is also provided on one side of the microwave dryer 1. The first chain 23, the second chain 251, the arc-shaped gear rod 252 and the circular gear rod 253 are located inside the protective cover 24. By setting the protective cover 24, the first chain 23, the second chain 251, the arc-shaped gear rod 252 and the circular gear rod 253 can be protected by the protective cover 24, reducing the possibility of accidental contact during use, reducing the possibility of unexpected damage, and reducing contact with air, thus reducing the possibility of corrosion and aging.

[0032] The specific working process of this embodiment includes: By utilizing the principle of microwave radiation in microwave dryer 1, the moisture in the medicine powder is directly heated and evaporated, thereby achieving a rapid drying effect on the medicine powder.

[0033] During drying: the powder is fed into the conveyor belt 4 through the hopper 6, and then the first motor 5 is started to drive the round shaft 3 to rotate, so as to drive the conveyor belt 4 to transport the powder into the microwave dryer 1. Then the microwave dryer 1 is started to dry and heat the powder. During the drying process, the second motor 22 is started, driving one of the sprocket stirring rods 21 to rotate. Under the transmission of the first chain 23, the remaining sprocket stirring rods 21 rotate synchronously on the conveyor belt 4, stirring the accumulated powder. At the same time, when one of the sprocket stirring rods 21 rotates, it drives the arc-shaped gear rod 252 to rotate under the transmission of the second chain 251. The arc-shaped gear rod 252 drives the circular gear rod 253 meshing with it to rotate within a preset angle range, causing the elastic reset member 254 to deform and be compressed. At this time, the end of part of the striking rod 255 will strike the conveyor belt 4 to make it vibrate, dispersing the powder accumulated on it. The incoming powder is vibrated and stirred. When the ends of the arc-shaped gear rod 252 and the circular gear rod 253 disengage, the elastic reset member 254 drives the circular gear rod 253 to reset under its own elastic restoring force. In this way, the striking rod 255 at the other end will also reset and strike the conveyor belt 4. Therefore, as the sprocket stirring rod 21 rotates, it drives several striking rods 255 to intermittently and reciprocally strike the conveyor belt 4 to prevent the powder from accumulating or clumping during the drying process, thereby improving the drying quality and efficiency of the powder, accelerating the evaporation of moisture, improving the performance of the microwave dryer 1, optimizing energy utilization, and reducing drying time.

[0034] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
