Description

Technical Field

[0001] This utility model relates to the field of granulation technology for granulated drugs, specifically to a high-efficiency boiling granulation device for granulated drugs. Background Technology

[0002] Currently, fluidized bed granulation, also known as fluidized bed granulation or one-step granulation, is a highly efficient and widely used granulation process. Fluidized bed granulation utilizes fluidizing gas to circulate powder within the device, and a binder is sprayed in to mix with the powder and form granules. This process takes place in a closed container. After the material is uniformly mixed, the binder is sprayed in at a constant speed to fully mix with the material and form small granules. Subsequently, hot air is introduced from the bottom to dry the wet granules, and finally, the finished dry granules are collected directly.

[0003] Currently, when powder materials are in a boiling state, spraying the binder liquid into the fluidized bed in the form of a mist through nozzles or atomizers creates dead zones, resulting in some powder not being sprayed, thus affecting the fluidized bed granulation effect. Moreover, due to the influence of pipelines, the binder and powder materials cannot fully contact and mix, making it difficult for the powders to bridge and aggregate into granules. In addition, the spraying part is located inside, making it difficult to disassemble, clean, and maintain. Utility Model Content

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see Figure 1-3 This utility model provides a technical solution: a high-efficiency fluidized bed granulation device for granular drugs, comprising:

[0023] Connecting frame 1, one end of which is connected to a conveying pipe 2;

[0024] An adhesive spraying structure is installed on the delivery pipe 2;

[0025] The adhesive spraying structure includes a snap-fit ​​frame 3, multiple fixing brackets 4, a reinforcing frame 5, a sealing frame 6, and a spraying ring 7. The outer wall of the snap-fit ​​frame 3 is slidably embedded in the delivery pipe 2. The sides of the multiple fixing brackets 4 that are far apart from each other are fixed in the snap-fit ​​frame 3. The inner wall of the reinforcing frame 5 is fixed on the snap-fit ​​frame 3. The snap-fit ​​frame 3 and the reinforcing frame 5 are sleeved on the delivery pipe 2. The inner wall of the sealing frame 6 is fixed on the snap-fit ​​frame 3. The outer wall of the spraying ring 7 is fixedly embedded in the multiple fixing brackets 4. A connecting pipe 8 is connected to the top of the outer wall of the spraying ring 7. The outer wall of the connecting pipe 8 is fixedly embedded in the delivery pipe 2.

[0026] In this implementation scheme: the connecting frame 1 allows air to flow, and under the action of the fan 11, positive pressure is generated inside, which in turn generates negative pressure in the top connecting part, thereby sucking up the powder and allowing the powder to enter the connecting frame 1. The clamping frame 3 is embedded in the conveying pipe 2 in an embedded manner and is fixed to the conveying pipe 2 by the reinforcing frame 5. At the same time, the sealing frame 6 squeezes the connection area between the clamping frame 3 and the conveying pipe 2 to prevent external air from entering the conveying pipe 2. Multiple fixing brackets 4 can fix the spraying ring 7 and keep it in a concentric state with the conveying pipe 2. The spraying ring 7 is connected to the external adhesive output device by the connecting pipe 8.

[0027] Specifically, multiple extension tubes 9 are provided at equal intervals along the circumferential surface on one side of the outer wall of the spray ring 7, and a spray head 10 is fixedly provided at the end of the multiple extension tubes 9 away from the spray ring 7.

[0028] In this embodiment: the spraying part of the spraying ring 7 can be extended into the conveying pipe 2 through multiple extension tubes 9, and the spraying head 10 is used to form atomization and spray it into the conveying pipe 2, so that the adhesive and powder material can fully contact and mix, and the powder can be bridged and aggregated into particles.

[0029] Specifically, the end of the connecting frame 1 away from the conveying pipe 2 is connected to a fan 11 and is also fitted with a central frame 12.

[0030] In this embodiment: when the fan 11 is powered on, the output end will generate wind power which is input into the connecting frame 1. The concentrator 12 is used to make the diameter of the input wind smaller than the diameter inside the connecting frame 1, so that negative pressure can be generated outside the connecting frame 1.

[0031] Specifically, a fixed frame 13 is connected to the top of the outer wall of the conveying pipe 2, and a reducing frame 14 is fixedly embedded in the inner wall of the fixed frame 13.

[0032] In this embodiment: the reducing frame 14 can be fixed to the top of the connecting frame 1 by the fixing frame 13. The reducing frame 14 adopts a structure with a larger inner diameter at the top and a smaller inner diameter at the bottom, which can prevent air from entering.

[0033] Specifically, a material conveying frame 15 is connected to the top of the outer wall of the fixed frame 13, and a fixed top plate 16 is fixedly provided on the top of the outer wall of the material conveying frame 15.

[0034] In this embodiment: the powder can be put into the feeding frame 15, and the inclined surface is used to make the powder slide into the reducing frame 14. The fixed top plate 16 can provide support for the bottom of the fixed frame 13.

[0035] Specifically, a hydraulic rod 17 is installed on the top of the outer wall of the fixed top plate 16, and a baffle 18 is fixedly installed at the output end of the hydraulic rod 17.

[0036] In this embodiment, the hydraulic rod 17 uses hydraulic pressure to drive the baffle 18 to slide up and down.

[0037] Specifically, the outer wall of the baffle 18 is slidably embedded in the fixed top plate 16 and slidably embedded in the material conveying frame 15.

[0038] In this embodiment, by sliding the baffle 18 to fix the top plate 16 and the conveying frame 15, the amount of powder entering the reducing frame 14 can be controlled, and better still, the adhesive and powder materials can fully contact and mix.

[0039] When in use, the blower 11 generates airflow at its output end when powered on, which is input into the connecting frame 1. The concentrating frame 12 ensures that the diameter of the input airflow is smaller than the diameter inside the connecting frame 1, thus creating negative pressure outside the connecting frame 1. The fixing frame 13 secures the reducing frame 14 to the top of the connecting frame 1. The reducing frame 14 has a structure with a larger inner diameter at the top and a smaller inner diameter at the bottom to prevent air from entering. The conveying frame 15 allows powder to be placed inside, and its inclined surface allows the powder to slide into the reducing frame 14. The fixing top plate 16 provides support to the bottom of the fixing frame 13. The hydraulic rod 17 uses hydraulic pressure to drive the baffle 18 to slide up and down. The baffle 18 slides and is fixed within the top plate 16 and the conveying frame 15, controlling the amount of powder entering the reducing frame 14. Furthermore, it ensures that the adhesive and powder materials are fully contacted and mixed. The connecting frame 1 allows airflow, and under the action of the fan 11, positive pressure is generated inside, creating negative pressure in the top connecting part, thereby sucking up the powder and allowing it to enter the connecting frame 1. The clamping frame 3 is embedded in the conveying pipe 2 in an embedded manner and is fixed to the conveying pipe 2 by the reinforcing frame 5. At the same time, the sealing frame 6 squeezes the connection area between the clamping frame 3 and the conveying pipe 2 to prevent external air from entering the conveying pipe 2. Multiple fixing brackets 4 can fix the spraying ring 7 and keep it concentric with the conveying pipe 2. The spraying ring 7 is connected to the external adhesive output device by the connecting pipe 8. Multiple extension pipes 9 can allow the spraying part of the spraying ring 7 to penetrate into the conveying pipe 2 and form an atomization by the spray head 10, spraying it into the conveying pipe 2, so that the adhesive and powder materials can fully contact and mix, and the powder can bridge and agglomerate into particles.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
