Description

Technical Field

[0001] This utility model relates to the field of drying tower technology, and in particular to a high-efficiency drying tower for spray drying microcrystalline embedded powder. Background Technology

[0002] Spray drying is a widely accepted drying process that has been extensively applied in the pharmaceutical, food, and chemical industries. It uses atomizing nozzles to turn liquid raw materials into a mist, which then comes into contact with hot air, thereby rapidly transforming the liquid raw materials into dry powder.

[0003] However, in the existing high-efficiency drying tower for spray-dried microcrystalline embedded powder, the hot air discharged inside is uneven, which causes the liquid raw materials to dry to different degrees when they are converted into powder. Some of the more moist powder is blown onto the inner wall by the hot air, causing the powder to stick to the inner wall, thus reducing the amount of powder produced, easily causing powder waste, and increasing production costs. When producing powder for moving wheels, more liquid raw materials need to be input. Utility Model Content

The lower end of the fixing plate 21 is connected to the lower end of the support frame 15 by bolt threads. The upper end of the fixing plate 21 has a slot corresponding to the motor 22. The fixing plate 21 and the motor 22 are connected by bolt threads. The outer side of the vibrator 23 is connected to the bottom end of the tank body 14 by bolt threads. The upper end of the annular air outlet 24 is fixedly connected to the bottom end of the sealing cover 11. The inner side of the 4 is provided with a corresponding groove for the annular air distribution plate 25. The inner side of the annular air outlet 24 is connected to the outer side of the annular air distribution plate 25 by bolt threads. The inner side of the separable seal 26 is provided with a corresponding groove for the motor 22. The bottom end of the tank body 14 is provided with a corresponding slot for the separable seal 26. The tank body 14 and the separable seal 26 are connected by bolt threads. The upper end of the elastic fixing member 29 is provided with two symmetrical elastic rods. The rear end of the scraper 28 is provided with a corresponding slot for the elastic rods on the elastic fixing member 29. The rear end of the scraper 28 is connected to the upper end of the elastic fixing member 29 by bolt threads. The rear end of the arc-shaped protrusion 291 is fixedly connected to the inner side of the tank body 14.

[0023] In this embodiment, the rear end of the air supply pipe 12 is connected to a hot air blower, which delivers hot air into the tank 14 through the air supply pipe 12. The rear end of the atomizing nozzle 13 is connected to a liquid raw material storage tank, and the liquid raw material is drawn by a pump installed inside the liquid raw material storage tank, so that the liquid raw material is transported to the atomizing nozzle 13, atomized by the atomizing nozzle 13 and sprayed out. The fixing plate 21 and the support frame 15 are connected by bolt threads. The upper end of the fixing plate 21 is provided with a corresponding slot for the motor 22. The fixing plate 21 and the motor 22 are connected by bolt threads. The vibrator 23 is connected to the tank 14 by bolt threads. The annular air outlet 24 is fixed to the sealing cover 11. The annular air outlet 24 has a corresponding groove on its inner side, which corresponds to the annular air distribution plate 25. The annular air outlet 24 and the annular air distribution plate 25 are connected by bolt threads. The inner side of the separable seal 26 has a corresponding groove for the motor 22.

The scraper 28 and the elastic fixing member 29 are connected by bolt threads. The arc-shaped protrusion 291 is fixedly connected to the tank body 14. The fixed plate 21 supports the motor 22. Hot air is blown into the tank 14 through the annular air outlet 24. The annular air outlet 24 and the annular air distribution plate 25 make the blown hot air more uniform, so that the atomized liquid raw material is heated more evenly and the air force is the same all around. This prevents the liquid raw material from being blown towards the inner wall of the tank 14 by uneven air force, which would cause the powder to stick to the inner wall of the tank 14 and result in material loss, reducing the amount of powder produced and increasing the raw material cost during production. The motor 22 drives the elastic fixing member 29 to rotate, which in turn causes the scraper 28 connected to the elastic fixing member 29 to rotate. The rotating scraper 28 can clean the powder adhering to the inner wall of the tank 14, preventing the powder from adhering to the inner wall and reducing the final powder output. The arc-shaped protrusion 291 set on the inner wall of the tank 14 can cause the elastic rod on the elastic fixing member 29 to bounce when the scraper 28 sweeps over the arc-shaped protrusion 291, thereby causing the scraper 28 to shake and shake off the powder adhering to the scraper 28. The vibration is amplified by the vibrator 23, which can make the powder adhering to the lower conical surface of the tank 14 fall off. The dried powder can be discharged from the tank 14 through the discharge pipe 27. The inside of the tank 14 can be observed by disassembling the detachable seal 26. Example

[0024] like Figure 1-5As shown, the collection mechanism 3 includes a collection tank 31, a sealing cover 32 at the upper end of the collection tank 31, a pressure relief pipe 33 at the upper end of the sealing cover 32, a fixing frame 34 at the left end of the pressure relief pipe 33, a suction fan 35 inside the fixing frame 34, and a receiving pipe 36 at the rear end of the suction fan 35. The anti-sticking mechanism 2 includes a discharge pipe 27. The upper end of the collection tank 31 is connected to the lower end of the sealing cover 32 by bolt threads. The upper end of the sealing cover 32 is provided with a corresponding slot for the pressure relief pipe 33. The sealing cover 32 is fixedly connected to the pressure relief pipe 33. The lower end of the fixing frame 34 is connected to the top end of the sealing cover 32 by bolt threads. The inner side of the fixing frame 34 is connected to the suction fan 35 by bolt threads. The sealing cover 32 is provided with a corresponding slot for the suction fan 35 on the side near the top. The rear end of the collection tank 31 is fixedly connected to the front end of the receiving pipe 36. The rear end of the receiving pipe 36 is connected to the front end of the discharge pipe 27 by bolt threads.

[0025] In this embodiment, the collection tank 31 and the second sealing cover 32 are connected by bolt threads. The upper end of the second sealing cover 32 is provided with a corresponding slot for the pressure discharge pipe 33. The second sealing cover 32 and the pressure discharge pipe 33 are fixedly connected. The fixing frame 34 is connected to the second sealing cover 32 by bolt threads, and the fixing frame 34 is connected to the suction fan 35 by bolt threads. The side of the second sealing cover 32 near the top is provided with a slot corresponding to the suction fan 35. The collection tank 31 is fixedly connected to the receiving pipe 36, and the receiving pipe 36 is connected to the discharge pipe 27 by bolt threads. When the suction fan 35 is started, suction force is generated by the suction fan 35. The dried powder is drawn into the collection tank 31 through the discharge pipe 27 and the feeding pipe for storage, facilitating further processing of the powder. The pressure relief pipe 33 allows air of equal volume to the powder to be discharged from the collection tank 31 while collecting the powder, facilitating the collection and storage of the powder. The fixing frame 34 provides fixation and support for the suction fan 35, facilitating its normal operation. The collection tank 31 and the sealing cover 32 protect the collected and stored powder, preventing external contaminants from contaminating the powder inside.

[0026] Working principle: like Figure 1-5As shown, the rear end of the air supply duct 12 is connected to a hot air blower, which delivers hot air into the tank 14 through the air supply duct 12. The rear end of the atomizing nozzle 13 is connected to a liquid raw material storage tank. A pump inside the liquid raw material storage tank draws the liquid raw material, which is then transported to the atomizing nozzle 13, atomized, and sprayed out. The fixing plate 21 provides support for the motor 22. The hot air is blown into the tank 14 through the annular air outlet 24. The annular air outlet 24 and the annular air distribution plate 25 ensure more even distribution of the hot air, allowing the atomized liquid raw material to be heated more effectively. The airflow is more uniform and the airflow force is the same on all sides, preventing uneven airflow force on the liquid raw material. This prevents the dried powder from being blown towards the inner wall of the tank 14, causing the powder to stick to the inner wall of the tank 14, resulting in raw material loss, reduced powder output, and increased raw material costs during production. The motor 22 drives the elastic fixing member 29 to rotate, which in turn rotates the scraper 28 connected to the elastic fixing member 29. The rotating scraper 28 can clean the powder adhering to the inner wall of the tank 14, preventing powder from adhering to the inner wall and reducing the final powder output. The arc-shaped protrusions 291 on the inner wall of the tank 14 cause the elastic rods on the elastic fixing member 29 to bounce when the scraper 28 sweeps over the arc-shaped protrusions 291, thereby causing the scraper 28 to vibrate and shake off the powder adhering to the scraper 28. The vibration is amplified by the vibrator 23, which can cause the powder adhering to the conical surface at the lower end of the tank 14 to fall off. The dried powder can be discharged from the tank 14 through the discharge pipe 27. The interior of the tank 14 can be observed by disassembling the detachable seal 26. The suction fan 35 is started, and the suction fan 35 generates suction. The force draws the dried powder through the discharge pipe 27 and the feeding pipe into the collection tank 31 for storage, facilitating further processing of the powder. The pressure relief pipe 33 allows air of equal volume to the powder to be discharged from the collection tank 31 while collecting the powder, facilitating the collection and storage of the powder. The fixing frame 34 provides fixation and support for the suction fan 35, facilitating its normal operation. The collection tank 31 and the sealing cover 32 protect the collected and stored powder, preventing external contaminants from contaminating the powder inside.
