Description

Technical Field

[0001] The utility model belongs to the technical field of pharmaceutical equipment, and specifically relates to a pharmaceutical vibrating screen. Background Art

[0002] The working principle of a pharmaceutical vibrating screen is similar to that of a general vibrating screening machine. It includes a screen body and one or more sieve meshes. The screen body and the sieve meshes generate a vibrating motion through a vibration force. Materials enter the screen body through the feed inlet. Under the action of vibration, smaller particles can pass through the pore diameter of the sieve mesh and fall into the lower discharge outlet, while larger particles cannot pass through the sieve mesh and remain in the screen body. The particle size of drugs has an important impact on properties such as solubility, absorbability, and stability. The pharmaceutical vibrating screen can select an appropriate sieve mesh pore diameter according to needs to achieve precise control of the particle size and ensure that the drugs meet the specified particle size range.

[0003] In order to screen out materials with particle sizes that meet the requirements, it is necessary to conduct layer-by-layer screening. The existing method generally involves multiple screenings, that is, screening one by one through sieves with different sieve pore diameters, and finally obtaining materials that meet the particle size requirements.

[0004] The existing standard sieve set for vibrating screens is usually composed of multiple sieve boxes with different sieve hole diameters stacked together and installed on the vibrating machine by a fixing component. Although this kind of vibrating screen can also complete the vibrating screening work of drug particles, in the process of use, due to the large variety of drug particles and the many required screening sizes, it is often necessary to replace sieve boxes with different sieve mesh hole sizes for combined use. However, the existing vibrating screen is inconvenient to operate when replacing sieve boxes with different sizes. Especially when only the bottom sieve box or the middle sieve box needs to be replaced, it is necessary to remove all the upper sieve boxes to replace the lower sieve box, and the operation is rather inconvenient. In view of this, the present utility model is specifically proposed. Summary of the Invention

[0005] The technical problem to be solved by the present utility model is to overcome the deficiencies of the prior art and provide a pharmaceutical vibrating screen that can overcome or at least partially solve the above problems.

[0006] To solve the above technical problems, the basic concept of the technical solution adopted by the present utility model is as follows: A medicinal vibrating screen includes a vibrator, and further includes: a cylinder body installed on the vibrator, and a cylinder cover is installed at the opening at the upper end of the cylinder body; a plurality of horizontal slots are equidistantly arranged on the cylinder body from top to bottom; a sieve plate is inserted into the horizontal slots, and the aperture diameters of the sieve holes on the plurality of sieve plates gradually decrease from top to bottom; an iron column is fixedly connected to the side of the sieve plate away from the opening of the horizontal slot; a through hole is opened at a position of the cylinder body close to the iron column, and the iron column is inserted into the through hole; a power supply board is fixedly installed on one side of the cylinder body close to the through hole; an electromagnet column is fixedly installed at the power supply end of the power supply board and is inserted into the through hole.

[0007] To facilitate improving the stability of the sieve plate in the cylinder body, further, the sieve plate includes a first semi-circular ring, a second semi-circular ring and a sieve mesh. A ring is fixedly formed between the first semi-circular ring and the second semi-circular ring. The thickness and height of the first semi-circular ring are both greater than those of the second semi-circular ring. The horizontal slot is adapted to the shape and particle size of the first semi-circular ring and the second semi-circular ring. The sieve mesh is fixedly connected inside the ring formed by the first semi-circular ring and the second semi-circular ring, and the iron column is fixedly connected to the second semi-circular ring.

[0008] To further facilitate improving the stability of the sieve plate in the horizontal slot and at the same time avoid some drug particles remaining in the gap between the sieve plate and the horizontal slot, still further, grooves are opened on both the upper and lower sides of the first semi-circular ring and the second semi-circular ring, and sealing rubber strips are embedded in the grooves.

[0009] To facilitate the staff to observe the screening situation of the drug particles, further, the cylinder body is designed to be transparent.

[0010] To facilitate discharging the drug particles with the smallest size from the cylinder body, further, the bottom of the cylinder body is arranged in a conical shape, and a discharge pipe is connected to the discharge port at the bottom of the cylinder body.

[0011] To facilitate improving the stability of the cylinder body, further, the cylinder body is welded to the mounting seat of the vibrator.

[0012] After adopting the above technical solution, the present utility model has the following beneficial effects compared with the prior art: By the combined use of components such as the cylinder body, the iron column, the power supply board, and the electromagnet column, compared with the existing medicinal vibrating screen, the present utility model can not only improve the stability of the sieve plate in the cylinder body and avoid the risk of the sieve plate falling off from the cylinder body, but also facilitate the rapid replacement of the sieve plate, effectively improving the efficiency of the staff in disassembling, installing and replacing the sieve plate.

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model but are not used to limit the scope of the present utility model. Embodiment 1

[0021] Referring to Figures 1-4 , a medicinal vibrating screen includes a vibrator 1 and further includes: a cylinder body 2 installed on the vibrator 1, a cylinder cover 201 installed at the opening at the upper end of the cylinder body 2; a plurality of horizontal slots are equidistantly opened downward from top to bottom on the cylinder body 2; a sieve plate 202 inserted into the horizontal slots, and the pore diameters of the sieve holes on the plurality of sieve plates 202 gradually decrease from top to bottom; an iron column 2025 fixedly connected to the side of the sieve plate 202 away from the opening of the horizontal slot; a through hole is opened on the cylinder body 2 near the iron column 2025, and the iron column 2025 is inserted into the through hole; a power supply board 203 fixedly installed on the side of the cylinder body 2 near the through hole; an electromagnet column 2031 fixedly installed at the power supply end of the power supply board 203 and inserted into the through hole.

[0022] When it is necessary to screen the particle size of pharmaceutical granular materials, select multiple sieve plates 202 with different sieve hole diameters according to the required particle size of the pharmaceutical granules, and insert the sieve plates 202 into the horizontal slots of the cylinder body 2 in sequence according to the diameter size of the sieve holes. Power supply is provided to the vibrator 1 and the power supply board 203. When the iron column 2025 on the sieve plate 202 abuts against the electromagnet column 2031, at this time, the power supply board 203 can supply power to the electromagnet column 2031, so that the electromagnet column 2031 obtains magnetic force to adsorb and fix the iron column 2025, and thus the sieve plate 202 can be firmly fixed in the cylinder body 2. Then, the cylinder cover 201 can be opened, and the pharmaceutical granules are poured into the cylinder body 2, so that the pharmaceutical granules are located on the uppermost sieve plate 202. Then, the vibrator 1 can be started to vibrate the cylinder body 2. The cylinder body 2 will vibrate the pharmaceutical granules through the sieve plate 202. Then, the smaller-sized pharmaceutical granules will pass through the sieve plate 202 and fall downward onto the lower sieve plate 202. Through screening time after time, the pharmaceutical granules that meet the specifications can be screened out. When the vibration screening is completed, at this time, the vibrator 1 can be turned off and the electromagnet column 2031 can be powered off. The staff can take out the multiple sieve plates 202 from the cylinder body 2 in sequence, and take down the pharmaceutical granules that meet the specifications from the corresponding sieve plates 202, and the pharmaceutical granules with the required specification particle size can be obtained. By the coordinated use of components such as the cylinder body 2, the iron column 2025, the power supply board 203, and the electromagnet column 2031, compared with the existing pharmaceutical vibrating sieve, not only can the stability of the sieve plate 202 in the cylinder body 2 be improved, avoiding the risk of the sieve plate 202 falling off from the cylinder body 2, but also it is convenient to quickly replace the sieve plate 202, effectively improving the efficiency of the staff in disassembling, installing, and replacing the sieve plate 202. Example 2

[0023] Refer to Figures 1-4 , a pharmaceutical vibrating sieve, which is basically the same as Example 1. Further: The sieve plate 202 includes a first semi-circular ring 2021, a second semi-circular ring 2022, and a sieve mesh 2023. A ring is fixedly formed between the first semi-circular ring 2021 and the second semi-circular ring 2022. The thickness and height of the first semi-circular ring 2021 are both greater than those of the second semi-circular ring 2022. The horizontal slot is adapted to the shapes and sizes of the first semi-circular ring 2021 and the second semi-circular ring 2022. The sieve mesh 2023 is fixedly connected inside the ring formed by the first semi-circular ring 2021 and the second semi-circular ring 2022. The iron column 2025 is fixedly connected to the second semi-circular ring 2022, as Figure 3As shown in the figure, by making the thickness and height of the first semi-circular ring 2021 greater than those of the second semi-circular ring 2022, when the staff inserts the sieve plate 202 into the horizontal slot, the sieve plate 202 can be stably located in the horizontal slot under the action of the height difference, improving the stability of the sieve plate 202, so that the electromagnetic column 2031 can more stably limit and fix the sieve plate 202 through the iron column 2025.

[0024] Grooves are provided on the upper and lower sides of the first semi-circular ring 2021 and the second semi-circular ring 2022, and sealing rubber strips 2024 are embedded in the grooves. Through the arrangement of the sealing rubber strips 2024, the sealing performance between the first semi-circular ring 2021, the second semi-circular ring 2022 and the cylinder body 2 can be improved. It can not only further improve the stability of the sieve plate 202 in the horizontal slot, but also prevent some drug particles from remaining in the gap between the sieve plate 202 and the horizontal slot. Embodiment 3

[0025] Refer to Figures 1-4 , a medicinal vibrating screen, which is basically the same as Embodiment 2. Further, the cylinder body 2 is designed to be transparent. When vibrating and screening the drug particles, the staff can watch the screening process of the drug particles through the cylinder body 2, so as to facilitate observing whether the drug particles have completed the screening work.

[0026] The bottom of the cylinder body 2 is arranged in a conical shape, and a discharge pipe is connected to the discharge port at the bottom of the cylinder body 2. By designing the bottom of the cylinder body 2 to be conical, it can play a guiding role for the drug particles passing through the lowest sieve plate 202, so that the drug particles with the smallest size can be discharged from the cylinder body 2 without removing the cylinder body 2.

[0027] The cylinder body 2 is welded to the mounting seat of the vibrator 1. By welding the cylinder body 2 to the vibrator 1, the cylinder body 2 and the vibrator 1 can be integrated, so that when the vibrator 1 drives the cylinder body 2 to vibrate, the stability of the cylinder body 2 can be ensured.
