Description

Technical Field

[0001] This utility model relates to the field of granulators, and more particularly to a one-step granulator for preparing pharmaceuticals. Background Technology

[0002] Granulation is the process of processing materials such as powders, liquids, and aqueous solutions into granules of a certain shape and size, making the products easier to package, carry, or measure. In modern industrial production, granulation is usually achieved through granulators, which are widely used in the pharmaceutical, chemical, and food industries.

[0003] Existing one-step granulation machines for pharmaceutical preparation use a blower to blow material from the hopper into the tank. The resulting granules fall through an adhesive sprayed from a nozzle. However, the amount of material falling cannot be adjusted as needed, which affects the use of the device. Therefore, a one-step granulation machine for pharmaceutical preparation is needed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a one-step granulator for preparing pharmaceuticals.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a one-step granulator for preparing pharmaceuticals, comprising a tank, an adhesive spray pipe fixedly connected inside the tank, a second air pipe fixedly connected inside the tank, a material tank fixedly connected to the top of the second air pipe, a slot provided inside the material tank, a retaining ring rotatably connected inside the slot, a first partition fixedly connected to the inner wall of the material tank, a first discharge hole provided inside the first partition, a rotating column rotatably connected to the top of the first partition, an output end of a motor fixedly connected to the top of the rotating column, a second partition fixedly connected to the inner wall of the retaining ring, a second discharge hole and a third discharge hole provided inside the second partition, the second and third discharge holes being arranged in a ring-shaped staggered distribution, the second discharge hole being the same as the first discharge hole, and the third discharge hole being smaller than the second discharge hole, a third partition fixedly connected to the circumferential surface of the rotating column, and a screen fixedly connected to the inner wall of the tank.

[0006] Furthermore, a fixing block is fixedly connected to the circumferential surface of the retaining ring, and multiple fixing blocks are provided, with anti-slip textures on the outside of the multiple fixing blocks.

[0007] Furthermore, a connecting plate is fixedly connected to the circumferential surface of the material tank, and the other end of the connecting plate is fixedly connected to the outer surface of the tank.

[0008] Furthermore: a feed pipe is fixedly connected to the top of the material tank, and a top cover is movably connected to the top of the feed pipe.

[0009] Furthermore, the tank body has a sliding groove inside, and a limit ring is slidably connected inside the sliding groove.

[0010] Furthermore: the bottom of the tank is threadedly connected to a first air pipe, which is located below the screen; a support frame is fixedly connected to the outside of the tank, which is located below the second air pipe.

[0011] This utility model has the following beneficial effects:

[0012] 1. Compared with existing technologies, this one-step granulator for preparing pharmaceuticals, by setting up a retaining ring, a second partition, a first partition, and a third partition, allows for adjustment. When the retaining ring is rotated, the material drop reaches its maximum when the second discharge hole corresponds to the first discharge hole, and its minimum when the third discharge hole corresponds to the first discharge hole. Furthermore, during operation, the motor is started, and the rotating column drives the third partition to rotate. During rotation, the third partition pushes the material towards the second and third discharge holes, causing the material to fall from the hole corresponding to the first discharge hole. This improves the practicality of the device and allows for adjustment of the material drop according to actual needs.

[0013] 2. Compared with existing technologies, this one-step granulator for preparing pharmaceuticals, by setting up a chute, a limiting ring, and a screen, allows the device to blow falling material into the tank through a second air pipe during the granulation process. The material is then blown upwards into the tank by air from the first air pipe and mixed with the adhesive sprayed from the adhesive nozzle, thus forming granules. When the granules reach a certain mass, they fall onto the screen. After granulation is complete, the limiting ring is pushed towards the top of the chute to collect the pharmaceutical granules on the screen, improving the convenience of pharmaceutical granule collection.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1-6This utility model provides a one-step granulator for preparing pharmaceuticals, comprising a tank 1, an adhesive spray pipe 2 fixedly connected inside the tank 1, a second air pipe 4 fixedly connected inside the tank 1, a material tank 5 fixedly connected to the top of the second air pipe 4, a slot 9 inside the material tank 5, a retaining ring 10 rotatably connected inside the slot 9, a first partition 6 fixedly connected to the inner side wall of the material tank 5, a first discharge hole 12 inside the first partition 6, and a rotating column rotatably connected to the top of the first partition 6. 7. The top of the rotating column 7 is fixedly connected to the output end of the motor 8. The inner side wall of the retaining ring 10 is fixedly connected to the second partition 11. The second partition 11 has a second discharge hole 13 and a third discharge hole 14 inside, and the second discharge hole 13 and the third discharge hole 14 are arranged in a ring-shaped staggered distribution. The second discharge hole 13 is the same as the first discharge hole 12, and the third discharge hole 14 is smaller than the second discharge hole 13. The circumferential surface of the rotating column 7 is fixedly connected to the third partition 15. The inner side wall of the tank 1 is fixedly connected to the screen 20. When adjusting the drop volume of material tank 5, rotating the retaining ring 10 will maximize the drop volume when the second discharge hole 13 corresponds to the first discharge hole 12, and minimize the drop volume when the third discharge hole 14 corresponds to the first discharge hole 12. During operation, starting the motor 8 and using the rotating column 7 to drive the third partition 15 to rotate will push the material towards the second and third discharge holes 13 and 14, allowing the material to fall from the hole corresponding to the first discharge hole 12. This improves the practicality of the lifting device and allows for adjustment of the material drop volume according to actual needs. The first partition 6, second partition 11, and third partition 15 are in contact with each other.

[0024] The retaining ring 10 is fixedly connected to a fixing block 17 on its circumferential surface. Multiple fixing blocks 17 are provided, and the outer surface of the multiple fixing blocks 17 is provided with anti-slip texture. The fixing blocks 17 make it easier to rotate the retaining ring 10.

[0025] A connecting plate is fixedly connected to the circumferential surface of the material tank 5, and the other end of the connecting plate is fixedly connected to the outer surface of the tank body 1. The connecting plate connects the material tank 5 and the tank body 1, so that the top of the material tank 5 remains fixed when the retaining ring 10 rotates.

[0026] A feed pipe 16 is fixedly connected to the top of the material tank 5, and a top cover is movably connected to the top of the feed pipe 16. Opening the top cover facilitates the addition of materials into the material tank 5 through the feed pipe 16.

[0027] The tank body 1 has a groove 18 inside, and a limit ring 19 is slidably connected inside the groove 18. The limit ring 19 can slide inside the groove 18.

[0028] The bottom of the tank 1 is threadedly connected to a first air pipe 3, which is located below the screen 20. A support frame 21 is fixedly connected to the outside of the tank 1, and the support frame 21 is located below the second air pipe 4. During the granulation process, air is blown from the second air pipe 4 into the tank 1, and the air is blown from the first air pipe 3 to the upper part of the tank 1 to mix with the adhesive sprayed from the adhesive spray pipe 2, thereby forming granules. When the granules reach a certain mass, they fall onto the screen 20. After granulation is completed, the limiting ring 19 is pushed to the top of the chute 18 to collect the drug granules on the screen 20, which improves the convenience of drug granule collection.

[0029] Working principle: When adjusting the drop amount of material tank 5, rotate the retaining ring 10. When the second discharge hole 13 corresponds to the first discharge hole 12, the drop amount of material reaches the maximum. When the third discharge hole 14 corresponds to the first discharge hole 12, the drop amount of material reaches the minimum. When in use, start the motor 8 and use the rotating column 7 to drive the third partition 15 to rotate. During the rotation, the third partition 15 pushes the material towards the second discharge hole 13 and the third discharge hole 14, so that the material falls from the hole corresponding to the first discharge hole 12. This improves the practicality of the lifting device and allows the drop amount of material to be adjusted according to actual needs.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
