[0002] In the process of drug production, the coarseness and fineness of the drug powder after crushing vary greatly. In order to meet the needs of medical treatment and drug preparation, a mesh-shaped tool is used to separate the coarse and fine powders from the coarse and fine mixed powders. This operation is called "sieving" or "sieving". Existing drug screening devices usually use a vibrating screen for screening. The vibrating screen is usually composed of multiple screen frames at different heights. The vibrating screen is provided with a vibration source vibrating screen frame to screen the drugs. During the screening process, some drugs are easy to break and will generate a lot of dust during the vibration process.

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Example 1

[0019] Reference Figure 1-4A material screening device for drug production includes a base, a vibrating screen 1 and a dust collection module are correspondingly arranged on the base, a dust collecting cover 2 is arranged directly above the vibrating screen 1, an air outlet pipe is arranged on the top of the dust collecting cover 2, a duct fan is installed in the air outlet pipe, and the air outlet pipe is connected to the dust collection module;

[0020] The dust collection module includes a drum 3, which is horizontally and rotatably mounted on a base. The drum 3 is connected to a driving mechanism 6 in a transmission manner. The driving mechanism 6 is used to drive the drum 3 to rotate. The driving mechanism 6 includes a support shaft, which is coaxially fixedly connected to the drum 3. A support plate is rotatably mounted on the support shaft, which is fixed on the base. The support shaft is connected to a motor in a transmission manner. The outer surface of the drum 3 is provided with a plurality of mounting grooves along the circumferential direction. A dust box 7 is installed in each mounting groove. The dust box 7 is rectangular in shape as a whole. The opening direction of the dust box 7 is arranged toward the outside of the drum 3. The opening of the dust box 7 is covered and fixed with a filter screen 8. The filter screen 8 is made of stainless steel. An air outlet pipe 9 is arranged on the side of the dust box 7. The air outlet pipe 9 is used to guide and discharge the gas filtered by the filter screen.

[0021] A docking cover 4 is provided above the top of the drum 3. The docking cover 4 is used to communicate with the dust collection module. The docking cover 4 includes a cover body. The cross section of the cover body is trumpet-shaped. An air inlet pipe is provided on the top of the cover body. The air outlet at the bottom of the cover body is arc-shaped and is arranged in close contact with the side of the drum 3. A sealing strip can be attached and fixed along the edge of the air outlet of the cover body to reduce the leakage of dust. The shape of the air outlet is in close contact with the drum 3, which can further improve the dust collection rate.

[0022] A collector 5 is provided on one side of the drum 3, and the collector 5 is used to collect dust in the dust box 7; the collector 5 is funnel-shaped as a whole, and the air inlet of the collector 5 is opened on the large-diameter end of the collector 5, and the air inlet of the collector 5 is arc-shaped and is arranged in close contact with the side of the drum 3. A collection bag can be set at the small-diameter end of the collector 5, and the dust falling along the collector 5 can be collected and bagged by the collection bag, which is more convenient to use.

[0023] When the utility model is in use, when the medicine is poured into the vibrating screen 1 for sieving operation, the generated dust will be sucked into the dust collecting hood 2 and finally discharged into the docking hood 4. At this time, any one of the dust collecting boxes 7 on the rotating drum 3 is aligned with the docking hood 4. When the gas containing dust in the docking hood 4 passes through the filter screen 8 on the dust collecting box 7, the dust will be intercepted by the filter screen 8, and the filtered gas is discharged through the air outlet pipe 9 on the dust collecting box 7. When the filter screen 8 on any one of the dust collecting boxes 7 collects more dust, the rotating drum 3 is rotated to rotate the dust collecting box 7 to align with the collector 5, and the dust on the filter screen 8 of the dust collecting box 7 is shaken off into the collector 5 for collection by shaking or the like. This can not only reduce dust pollution, but also collect and utilize the medicine dust.

[0024] Example 2

[0025] Reference Figure 3 As another preferred embodiment of the utility model, the difference from embodiment 1 is that a docking pipe 10 is provided on one side of the collector 5, and the docking port of the docking pipe 10 is arranged corresponding to the motion trajectory plane of the outer port of the air outlet pipe 9, so that the air outlet pipe 9 can be docked and connected with the docking pipe 10 in turn during the movement, and the docking pipe 10 is connected with a hair dryer. When the drum 3 drives any dust box 7 to move to the position of the collector 5, the dust box 7 rotates against the collector 5. At this time, it is necessary to use peripheral equipment to beat the dust box 7 so that the dust on the internal filter screen of the dust box 7 is shaken off, and the shaken off dust can fall into the collector 5, which is inconvenient. For this reason, a docking pipe 10 is provided. When a dust box 7 moves to the position of the collector 5, the docking pipe 10 is docked with the air outlet pipe 9 on the dust box 7, and the hair dryer is then started to blow gas into the dust box 7, and the gas reversely impacts the filter screen 8, thereby recoiling the dust into the collector 5, which is not only more convenient, but also collects more dust. An elastic sealing ring is provided at the butt joint port of the butt joint pipe 10. The elastic sealing ring can improve the sealing performance between the butt joint pipe 10 and the air outlet pipe 9 when the butt joint pipe 10 is connected.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
