Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, and in particular to a multi-layer graded material impurity removal and screening device for pharmaceutical production. Background Technology

[0002] In the pharmaceutical production process, the purity of materials directly determines the quality and safety of the final product. Therefore, material screening and impurity removal is a key preliminary step in the pharmaceutical production process.

[0003] A drug screening device is disclosed in patent document CN221753847U. The device is equipped with a connecting frame, a motor, a guide plate, and a screening component. When the device is in use, the motor installed on the top surface of the connecting frame drives the rotation of the guide plate and the screening component. Since the screening component has a brush structure, when the screening component rotates, it can not only screen the tablets located on the bottom plate at the same time, but also maintain the integrity of the tablets as much as possible through the flexible brush structure, thus further improving the overall reliability of the device.

[0004] However, the screening devices in the aforementioned comparative documents employ a single-level screening structure, resulting in limited screening accuracy. This makes it difficult to accurately separate materials of different particle sizes from impurities, leading to residual impurities in the screened material. Consequently, the purity of the material may not meet the quality standards for pharmaceutical production, posing potential risks to subsequent formulation processing and drug efficacy stability. Therefore, we provide a multi-level grading and impurity removal screening device for pharmaceutical production. Utility Model Content

[0018] 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.

[0019] Example 1 To address the issue in the prior art where multi-stage material screening is difficult, potentially leading to reduced pharmaceutical production quality, this embodiment provides a multi-layer grading material removal and screening device for pharmaceutical production. This device enables multi-stage screening of materials, thereby improving removal efficiency and enhancing pharmaceutical production quality. Please refer to... Figure 1 - Figure 5 The multi-layer graded material removal and screening device for pharmaceutical production includes a dustproof box 2 installed at the top of the frame 1. Inside the dustproof box 2, at the top, there are guide plates distributed below the feed inlet to guide the material to be evenly dispersed to the screen frame 35, so as to avoid the material from accumulating and affecting the screening uniformity. The frame 1 is equipped with a screening component 3 for multi-stage screening of materials and a vibration component 4 to prevent the material from clogging the screen holes. The dustproof box 2 is equipped with a dust removal component 5 to absorb the dust generated by the screening material.

[0020] The screening equipment used in the comparison document adopts a single-level structure, which has limited screening accuracy and makes it difficult to accurately classify and separate materials and impurities of different particle sizes. As a result, some impurities remain in the screened material, and the purity is difficult to meet the pharmaceutical production quality standards. In order to solve the above problems.

[0021] Screening assembly 3 includes a drive motor 31 mounted on a frame 1. Two symmetrically distributed load-bearing components 32 are mounted on the top of the frame 1. A rotating rod 33 is rotatably mounted between the two load-bearing components 32. A turntable 34, connected to a connecting disc on the output shaft of the drive motor 31 via a connecting belt, is mounted on the middle of the outer wall of the rotating rod 33. A screen frame 35 is slidably connected to the lower part of the interior of the dustproof box 2. The end of the screen frame 35 near the guide frame 38 has an open structure, allowing the material after the initial screening to smoothly enter the guide frame 38, reducing material loss. To prevent material retention and ensure the continuity of the screening process, a connecting rod 36 is rotatably connected to one end of the screen frame 35 and the other end of the rotating rod 33. Multiple sets of load-bearing rollers 37 are symmetrically distributed and in contact with the bottom of the screen frame 35 at the dustproof box 2 on the frame 1. A guide frame 38 is installed on the side of the frame 1 and distributed on the side of the screen frame 35. A screen plate 39 is installed in the middle of the frame 1 and distributed below the screen frame 35. A collection box 310 and a bottom frame 311 are respectively provided on the side and directly below the screen plate 39 to achieve the grading and impurity removal of materials.

[0022] After the drive motor 31 starts, the connecting disc on its output shaft connects to the turntable 34 via a belt, causing the rotating rod 33 to rotate synchronously under the support of two sets of load-bearing components 32. At the same time, one end of the rotating rod 33 pulls the screen frame 35 through the connecting rod 36, causing the screen frame 35 to slide back and forth on the load-bearing rollers 37 of the frame 1. The material falls evenly into the screen frame 35 through the guide plate at the top of the dustproof box 2. After the initial screening by the screen frame 35, the larger particle size material enters the guide frame 38 from the open end of the screen frame 35 near the guide frame 38. The remaining material falls to the screen plate 39 below the screen frame 35 for secondary screening. The material that meets the requirements enters the collection box 310 on the side of the screen plate 39, while the fine impurities fall into the bottom frame 311 directly below the screen plate 39, completing multi-stage grading and impurity removal, and improving the production efficiency of the reagent.

[0023] Example 2 Based on Example 1, such as Figure 1 - Figure 5 As shown, based on the existing comparative documents, it is not easy to screen materials in multiple stages, which can easily reduce the quality of reagent production. However, the comparative documents lack a dust control structure, which can easily generate dust during the screening process, polluting the screening environment and wasting materials. Therefore, the device is also equipped with a structure to prevent material blockage and remove dust.

[0024] The comparison document lacks an effective dust control structure, which easily generates a large amount of dust during screening operations. This not only pollutes the working environment but also leads to material loss and waste, and fails to protect the health of operators. In order to solve the above problems...

[0025] The vibration assembly 4 includes a fixed disk 41 mounted on the output shaft of the drive motor 31, and mounting rods 42 rotatably connected to the inner side of the frame 1, distributed below the screen plate 39. One end of the mounting rod 42 is mounted with a linkage disk 43, which is in the same vertical plane as the fixed disk 41. The fixed disk 41 and the linkage disk 43 have different diameters. The rotation speed of the mounting rod 42 is adjusted by differential transmission so that the striking element 46 can obtain a striking frequency suitable for screening requirements. A linkage belt 44 is provided between the linkage disk 43 and the fixed disk 41. Multiple sets of fixed cylinders 45 are installed on the outer wall of the mounting rod 42. The striking element 46 is slidably connected inside each set of fixed cylinders 45 to strike the screen plate 39 to prevent material from clogging the screen holes. The top of the striking element 46 is an elastic silicone ball structure, which can effectively strike the screen plate 39 to prevent clogging and avoid damage to the screen plate 39, ensuring stable operation of the equipment. A connecting spring 47 is connected between the striking element 46 and the fixed cylinder 45 to expand the vibration range of the striking element 46.

[0026] The dust removal assembly 5 includes a vacuum cleaner 51 and a dust hood 52 respectively installed on the top two sides and the front and rear sides of the dust box 2. A suction pipe 53 is provided between the vacuum cleaner 51 and the dust hood 52. The two sets of dust hoods 52 are staggered on the front and rear sides of the dust box 2 and are located above the screen frame 35. They can fully cover the screening area of ​​the screen frame 35, avoid the formation of dust dead corners, efficiently absorb the dust generated during screening, and reduce the spread of dust and environmental pollution. A suction pipe 53 is provided between the vacuum cleaner 51 and the dust hood 52.

[0027] When the drive motor 31 is running, it synchronously drives the fixed disk 41 on its output shaft to rotate. The fixed disk 41 is connected to the linkage disk 43 through the linkage belt 44. Because the fixed disk 41 and the linkage disk 43 have different diameters, the linkage disk 43 drives the mounting rod 42 to rotate at an appropriate speed. Multiple sets of fixed cylinders 45 on the outer wall of the mounting rod 42 rotate synchronously with the mounting rod 42. The striking parts 46 inside the fixed cylinders 45 continuously strike the bottom of the screen plate 39 under the combined action of centrifugal force and connecting spring 47. At the same time, the connecting spring 47 expands the vibration range of the striking parts 46, effectively preventing material accumulation and clogging of the screen holes of the screen plate 39. During the screening process, the dust generated when the material is screened on the screen frame 35 and screen plate 39 is contained by the dust box 2 to prevent it from spreading randomly. At this time, the vacuum cleaner 51 starts to generate negative pressure suction. The suction is transmitted through the suction pipe 53 to the two sets of suction hoods 52 that are staggered on the front and back sides of the dust box 2 and located above the screen frame 35. The dust is captured by the suction hoods 52 under the action of negative pressure and transported to the vacuum cleaner 51 through the suction pipe 53 for collection and treatment, thereby realizing the dust purification during the screening process.

The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
