Description

Technical Field

[0001] This utility model belongs to the field of drying equipment technology, and in particular relates to a product drying device for norfloxacin production. Background Technology

[0002] Norfloxacin, also known as norfloxacin, is a third-generation quinolone antibiotic. It inhibits the action of DNA gyrase in pathogenic bacteria in the digestive tract, thus preventing bacterial DNA replication and having an inhibitory effect on bacteria. During the production of norfloxacin, the product used in its production process needs to be dried. Norfloxacin raw material has the characteristic of absorbing moisture in the air and gradually darkening in color when exposed to light. This provides conditions for it to clump during processing. If the material is not sufficiently dispersed in the granulation and mixing processes before drying, it is easy to clump due to moisture absorption or its own properties. A search of existing Chinese patent technology revealed a "drying device for norfloxacin production" with publication number "CN222257517U". This device rotates a paddle in a trough, causing the norfloxacin production product to slide evenly from the material hole onto the conveyor belt. However, during the conveying process, this device may cause uneven distribution of agglomerated powder, resulting in powder stacking and affecting the uniform drying effect of the powder. Utility Model Content

[0003] The purpose of this invention is to solve the problem of uneven distribution of agglomerated drug powder, which causes the powder to overlap during transportation and affects the uniform drying effect of the drug powder. Therefore, this invention proposes a product drying device for norfloxacin production.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A product drying apparatus for norfloxacin production includes: a mounting frame with a feeding hopper installed on its inner side; a drying mechanism installed on the inner side of the mounting frame, the surface of which extends to the outside of the mounting frame; wherein the drying mechanism includes a servo motor installed on the outside of the mounting frame, the output shaft of which extends to the inside of the mounting frame, a conveying assembly installed inside the mounting frame, a drying assembly positioned above the conveying assembly, the drying assembly being installed on the inner side of the mounting frame, and a leveling assembly positioned between the conveying assembly and the drying assembly.

[0005] As a further description of the above technical solution: The averaging component includes a rotating shaft rotatably connected to the inside of the mounting frame. A swing plate is provided on the side of the rotating shaft away from the feeding hopper. Both ends of the swing plate extend to the outside of the mounting frame. An airbag is fixedly connected to the surface of the rotating shaft. Multiple brushes are fixedly connected to the lower end of the swing plate. Two connecting frames are fixedly connected to the lower end of the swing plate.

[0006] As a further description of the above technical solution: The conveying assembly includes two rotating rollers rotatably connected to the inner wall of the mounting frame. A conveyor belt is fitted on the surface of the rotating rollers. One side of one of the rotating rollers is fixedly connected to the output shaft of a servo motor. One end of one of the rotating rollers is fixedly connected to one end of the rotating shaft, and a pulley is fitted on the surface of both pulleys.

[0007] As a further description of the above technical solution: The drying assembly includes a heat insulation frame fixedly connected to the inside of the mounting frame. The heat insulation frame is located above the conveying assembly. Multiple reflective arc plates are fixedly connected to the inner top wall of the heat insulation frame. Connecting seats are fixedly connected to both sides of the reflective arc plates. Multiple drying lamps are fixedly connected between two of the connecting seats.

[0008] As a further description of the above technical solution: The airbag is fixedly connected to two ends with abutting arc blocks, and the two abutting arc blocks are longitudinally symmetrically distributed along the axis of rotation.

[0009] As a further description of the above technical solution: The end of the connecting frame away from the brush is fixedly connected to a collar, which is sleeved on the surface of the rotating shaft.

[0010] As a further description of the above technical solution: The surface of the airbag is provided with multiple annular grooves, which are distributed in a straight line along the surface of the airbag.

[0011] As a further description of the above technical solution: The multiple connecting seats are arranged in a straight line along the inner top wall of the heat insulation frame, and the drying lamp is located inside the reflector plate.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: 1. In this utility model, a conveying component is provided inside. The rotating shaft drives the airbag and the contact arc block to rotate synchronously. The multiple annular grooves on the surface of the airbag can assist in the extrusion and separation of the raw materials, so that the medicine powder forms a strip-shaped trajectory and is distributed above the conveyor belt for conveying. As the contact arc block rotates with the rotating shaft, the contact connecting frame swings. At this time, the swing plate follows the connecting frame and drives the brush to disperse the medicine powder of the strip-shaped trajectory above the conveyor belt, so that the medicine powder is distributed more evenly, reducing the accumulation of medicine powder during the conveying process and ensuring the uniform drying and processing effect of medicine powder. 2. In this utility model, a drying component is provided inside, and a servo motor drives the rotating roller to rotate, so that the conveyor belt carries the medicine powder for drying. The pulley and the transmission belt drive the rotating shaft to rotate synchronously, and the medicine powder can be dried by the setting of drying lamps. The setting of heat insulation frame reduces heat dissipation, and the setting of reflector plate can reflect the heat generated by the drying lamps to the medicine powder on the conveyor belt, thereby improving the drying effect.

[0015] The utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are only descriptive and are not intended to limit the scope of protection of this utility model.

[0016] In its specific implementation, such as Figures 1-5 This utility model provides a technical solution comprising: a mounting frame 1, with a feeding bin 2 mounted on the inner side of the mounting frame 1; a drying mechanism 3, mounted on the inner side of the mounting frame 1, with the surface of the drying mechanism 3 extending to the outer side of the mounting frame 1; wherein, the drying mechanism 3 includes a servo motor 34 mounted on the outer side of the mounting frame 1, the output shaft of the servo motor 34 extending to the interior of the mounting frame 1, a conveying assembly 31 mounted inside the mounting frame 1, a drying assembly 33 disposed above the conveying assembly 31, the drying assembly 33 mounted on the inner side of the mounting frame 1, and a spreading assembly 32 disposed between the conveying assembly 31 and the drying assembly 33; like Figures 1-3 As shown, the equalization component 32 includes a rotating shaft 321 rotatably connected to the inner side of the mounting frame 1. A swing plate 324 is provided on the side of the rotating shaft 321 away from the feeding bin 2. Both ends of the swing plate 324 extend to the outside of the mounting frame 1. An airbag 322 is fixedly connected to the surface of the rotating shaft 321. A plurality of brushes 325 are fixedly connected to the lower end of the swing plate 324. Two connecting frames 326 are fixedly connected to the lower end of the swing plate 324. The two ends of the airbag 322 are fixedly connected to the abutting arc blocks 323. The two abutting arc blocks 323 are longitudinally symmetrically distributed along the axis of the rotating shaft 321. The end of the connecting frame 326 away from the brush 325 is fixedly connected to the collar 328. The collar 328 is sleeved on the surface of the rotating shaft 321. The surface of the airbag 322 is provided with multiple annular grooves 327. The multiple annular grooves 327 are linearly distributed along the surface of the airbag 322. Specifically, the device rotates via a rotating shaft 321, causing the airbag 322 and the contact arc block 323 to rotate synchronously. Multiple annular grooves 327 on the surface of the airbag 322 can assist in the extrusion and separation of the raw material, so that the powder forms a strip-shaped trajectory and is distributed above the conveyor belt 312 and conveyed accordingly. As the contact arc block 323 rotates with the rotating shaft 321, it pushes the connecting frame 326 to swing. At this time, the swing plate 324 drives the brush 325 along with the connecting frame 326 to evenly disperse the powder in the strip-shaped trajectory above the conveyor belt 312, thereby making the powder distribution more uniform. like Figure 2 , Figure 4 , Figure 5As shown, the conveying assembly 31 includes two rotating rollers 311 rotatably connected to the inner wall of the mounting frame 1. A conveyor belt 312 is sleeved on the surface of the rotating rollers 311. One side of one rotating roller 311 is fixedly connected to the output shaft of the servo motor 34. A pulley 313 is fixedly connected to one end of one rotating roller 311 and one end of the rotating shaft 321. A transmission belt 314 is sleeved on the surface of the two pulleys 313. The drying assembly 33 includes a heat insulation frame 331 fixedly connected to the inner side of the mounting frame 1. The heat insulation frame 331 is located above the conveying assembly 31. Multiple reflective arc plates 332 are fixedly connected to the inner top wall of the heat insulation frame 331. Connecting seats 333 are fixedly connected to both sides of the reflective arc plates 332. Multiple drying lamps 334 are fixedly connected between two connecting seats 333. The multiple connecting seats 333 are arranged in a straight line along the inner top wall of the heat insulation frame 331. The drying lamps 334 are located inside the reflective arc plates 332. Specifically, the device drives the rotating roller 311 to rotate via the servo motor 34, which in turn causes the conveyor belt 312 to carry the powder for drying. The pulley 313 and the transmission belt 314 drive the rotating shaft 321 to rotate synchronously. The drying lamp 334 dries the powder, the heat insulation frame 331 reduces heat loss, and the reflector plate 332 reflects the heat generated by the drying lamp 334 onto the powder on the conveyor belt 312, thereby improving the drying effect.

[0017] Working principle: When the device is working, the servo motor 34 drives the rotating roller 311 to rotate, which in turn drives the conveyor belt 312 to move, so that the medicine powder moves on the conveyor belt 312 and is dried. Through the cooperation of the pulley 313 and the transmission belt 314, the rotating shaft 321 is driven to rotate synchronously. The rotation of the rotating shaft 321 further drives the airbag 322 and the contact arc block 323 on it to rotate together. When the contact arc block 323 rotates with the shaft to a specific position, it will abut and push the connecting frame 326 to form an oscillation. This oscillation is transmitted through the oscillation plate 324, which finally drives the brush 325 to move and disperse the medicine powder on the conveyor belt 312 to ensure that the medicine powder is evenly spread. While the medicine powder is being dispersed, the drying lamp 334 above is turned on to dry the medicine powder. The reflective arc plate 332 set in the device can reflect the heat generated by the drying lamp 334 onto the medicine powder on the conveyor belt 312 more concentratedly, thereby significantly improving the drying efficiency and effect.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
