Description

Technical Field

[0001] This utility model relates to the field of granule drug production technology, and in particular to a device for granulation in drug production. Background Technology

[0002] In pharmaceutical manufacturing, granulation of large pharmaceutical materials is a crucial process. This involves crushing, screening, and granulating granules to meet the requirements of subsequent formulation processes. Traditional granulation equipment typically uses a tank structure with internal grinding blades and mesh, achieving granulation of the pharmaceutical materials through their mechanical interaction. Its structural design and function directly impact production efficiency and product quality.

[0003] In existing technologies, the top cover of granulation equipment used in pharmaceutical production is typically a fixed structure, with the top cover and tank body secured by snap-fit ​​connections to ensure sealing and stability. The grinding blades are usually directly fixed to the drive shaft and rotated by a motor, working in conjunction with the grinding screen to grind and granulate the material. While this design is simple and reliable, it still has certain limitations in practical use.

[0004] However, in traditional pharmaceutical granulation equipment, the cleaning of the tank interior is complex and cumbersome due to the fixed connection between the top cover and the tank body. Opening and closing the top cover requires removing multiple fasteners, which is not only time-consuming and labor-intensive but also affects the sealing performance of the equipment. Furthermore, the distance between the grinding blades and the grinding mesh is usually fixed and cannot be adjusted according to the hardness of the material or process requirements, resulting in poor adaptability to different materials and affecting granulation effect and production efficiency. Therefore, there is an urgent need for a granulation device that is easy to open and has an adjustable grinding gap to improve practicality and adaptability. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a device for granulation in pharmaceutical production, which aims to improve the problem of inconvenience in opening the tank when cleaning the inside of the tank in traditional pharmaceutical granulation devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a device for granulation in pharmaceutical production, comprising a base, a vertical rod fixedly connected to the top of the base, a tank body fixedly connected to the outer wall of the vertical rod, a second fixing plate fixedly connected to the outer wall of the tank body, a connecting rod fixedly connected to the top of the second fixing plate, a first fixing plate fixedly connected to the top of the connecting rod, a first fixing plate fixedly connected to the outer wall of the tank body, a first rotating shaft rotatably connected inside the first fixing plate, a movable plate fixedly connected to the top of the first rotating shaft, a top cover fixedly connected to one side of the movable plate, a locking plate fixedly connected to one side of the top cover, a fixing block fixedly connected to the other side of the tank body, and a locking assembly provided inside the fixing block;

[0007] The locking assembly includes a second rotating shaft, which is rotatably connected inside the fixed block. A threaded rod is fixedly connected to the top of the second rotating shaft, and a knob is sleeved on the outer wall of the threaded rod.

[0008] As a further description of the above technical solution:

[0009] A feed pipe is fixedly connected to the top of the top cover, a feed hopper is fixedly connected to the top of the feed pipe, and a discharge port is fixedly connected to the outer wall of the tank.

[0010] As a further description of the above technical solution:

[0011] A bottom plate is fixedly connected to the bottom of the tank, a fixing sleeve is fixedly connected inside the bottom plate, a base plate is fixedly connected to the top of the fixing sleeve, and a grinding mesh is fixedly connected to the top of the base plate.

[0012] As a further description of the above technical solution:

[0013] A fixed plate is provided on the top of the chassis, and a rotating shaft three is fixedly connected to the bottom of the fixed plate. The top of the rotating shaft three is rotatably connected inside the fixed sleeve.

[0014] As a further description of the above technical solution:

[0015] A connector is provided at the bottom of the fixed plate, and a grinding blade is fixedly connected to one end of the connector.

[0016] As a further description of the above technical solution:

[0017] The fixed plate has a connection hole inside, and the connector has a threaded hole inside.

[0018] As a further description of the above technical solution:

[0019] The fixing plate has screws inside, and the screws are threaded into the connecting hole and the threaded hole.

[0020] As a further description of the above technical solution:

[0021] A protective cover is fixedly connected to the bottom of the base plate, a motor is fixedly connected inside the protective cover, a flange is fixedly connected to the output end of the motor, and the top of the flange is fixedly connected to the bottom of the rotating shaft.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the locking plate fixed to the outer wall of the feed pipe and the fixing block fixed to the outer wall of the tank are first connected by a threaded rod and a knob. The threaded rod rotates around the fixing block through a rotating shaft fixed at one end. Then, the top cover and the tank are locked or unlocked by rotating the knob. The feed pipe rotates around the fixing plate and the fixing plate through a rotating shaft fixed at the bottom of the movable plate, thereby making the feed pipe rotate relative to the tank, achieving the function of opening the top cover of the tank. This solves the problem of inconvenience in opening the tank when cleaning the inside of the tank in traditional pharmaceutical granulation devices, and improves the practicality of pharmaceutical granulation devices.

[0024] 2. In this utility model, the fixing plate is connected to the connector at the bottom by screws, thereby fixing the grinding blade. The connector has multiple threaded holes, and the fixing plate also has connecting holes. The screws are passed through the connecting holes and threaded into the threaded holes. By fixing to different threaded holes, the gap between the grinding blade and the grinding mesh can be adjusted. This solves the problem that traditional pharmaceutical granulation devices cannot adjust the distance between the grinding blade and the grinding mesh, which makes them unable to adapt to the granulation needs of materials with different hardness, and improves the adaptability of pharmaceutical granulation devices.
