[0023] Referring to Figure 3 In this embodiment, the connecting column 205 drives the rectangular clamping plate 204 to be positioned and connected with the rectangular frame 203 through the connecting hole 207. First, select the appropriate aperture screen plate according to the needs, then arrange and place it from top to bottom, then pick up the rectangular clamping plate 204, the connecting column 205 drives it to be positioned and connected with the rectangular frame 203 through the connecting hole 207, then repeat the above operation to assemble the remaining screen plates. The rectangular clamping plate 204 drives the rectangular frame 203 to be positioned and connected with the box body 1 along the U-shaped clamping groove 103. When the assembly is complete, pick up the U-shaped handle 206, then the rectangular clamping plate 204 drives the rectangular frame 203 to be positioned and connected with the box body 1 along the U-shaped clamping groove 103.
[0024] Referring to Figure 4 In this embodiment, the inlet pipe 3 is externally sleeved with a back-shaped cover plate 301 at the lower end. The back-shaped cover plate 301 is symmetrically fixedly installed with arc-shaped handles 302 at both ends. The back-shaped cover plate 301 is installed with clamping columns 303 at the lower end corners corresponding to the clamping holes 104. When the screen plates are placed, pick up the arc-shaped handles 302, then the clamping columns 303 drive the back-shaped cover plate 301 to be positioned and connected with the box body 1 through the clamping holes 104. A rotating column 304 is transversely provided in the middle of the inlet pipe 3. The rotating column 304 is installed with a motor 305 at one end. A plurality of arc-shaped separation pieces 306 are installed around the outside of the rotating column 304. When the assembly is complete, the rotating column 304 drives the arc-shaped separation pieces 306 to rotate through the driving of the motor 305. Then the pharmaceutical particles are poured along the inlet pipe 3. At the same time, the arc-shaped separation pieces 306 uniformly deliver the pharmaceutical particles in batches to the large-hole screen plate 2 for screening treatment.
[0025] In operation, first, select the appropriate aperture screen plate according to the needs, then arrange and place it from top to bottom, then pick up the rectangular clamping plate 204, the connecting column 205 drives it to be positioned and connected with the rectangular frame 203 through the connecting hole 207, then repeat the above operation to assemble the remaining screen plates. When the assembly is complete, pick up the U-shaped handle 206, then the rectangular clamping plate 204 drives the rectangular frame 203 to be positioned and connected with the box body 1 along the U-shaped clamping groove 103.
[0026] When the screen plates are placed, pick up the arc-shaped handles 302, then the clamping columns 303 drive the back-shaped cover plate 301 to be positioned and connected with the box body 1 through the clamping holes 104.

[0028] During the screening of pharmaceutical particles, the screened powder falls along the discharge pipe 101, and a receiving container can be placed below the discharge pipe 101 to prevent the powder from scattering. After screening is complete, the feed pipe 3 is opened and the U-shaped handle 206 is lifted to remove the screened particles in batches.
[0029] Through the above steps, according to the need to distinguish the size of pharmaceutical particles, the large-hole screening plate 2 with appropriate pore size is selected for assembly and use, then the pharmaceutical particles are poured into the box 1 through the feed pipe 3, and multi-stage screening is performed by the large-hole screening plate 2 to distinguish pharmaceutical particles of different sizes. Then the powder falls out through the discharge pipe 101 at the lower end of the box 1, and finally the feed pipe 3 is disassembled, the large-hole screening plate 2 is removed, and the screened particles are removed.
