DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0020] As Figure 1 —shown in Figure 2, a fine filtration device for drug preparation includes a cylinder body 1. A screening mechanism 2 is arranged inside the cylinder body 1. A crushing mechanism 3 is arranged at the top of the cylinder body 1. A base 4 is arranged below the cylinder body 1. Support plates 5 are fixedly installed on both sides of the base 4, and the other side of the support plate 5 is fixedly connected to the side surface of the cylinder body 1. A sieve plate 8 is fixedly installed inside the cylinder body 1, and the sieve plate 8 is located below the screening mechanism 2.

[0021] The effects achieved by the above components are as follows: By setting the screening mechanism 2 to screen the particles in the drug to obtain drug particles within a specific particle size range, the function of controlling the particle size distribution is achieved, thereby facilitating the subsequent processing and use of the drug. By setting the crushing mechanism 3 to crush the large particles in the drug, the large particles are crushed into small particles within the required particle size range, avoiding waste of large particles and improving the utilization rate of drug particles.

[0022] As Figure 3 shown, the screening mechanism 2 includes a sieve cylinder 201. The sieve cylinder 201 is located inside the cylinder body 1. Uniformly distributed sieve holes 202 are formed on the surface of the sieve cylinder 201. Uniformly distributed convex teeth 203 are fixedly installed on the outer surface of the sieve cylinder 201. A through groove is formed on the right side of the cylinder body 1. A first motor 204 is fixedly installed on the right side of the cylinder body 1. The output end of the first motor 204 is fixedly installed with a driving gear 205. The left side of the driving gear 205 penetrates through the through groove and extends into the inside of the cylinder body 1. The driving gear 205 meshes with the convex teeth 203. The aperture of the sieve hole 202 is the same as that of the sieve plate 8.

[0023] The effects achieved by the above components are as follows: By setting the first motor 204 to drive the driving gear 205 to rotate, and then the driving gear 205 drives the convex teeth 203 to rotate, the convex teeth 203 drive the sieve cylinder 201 to rotate. The sieve cylinder 201 rotates to rotate the drug particles inside the sieve cylinder 201. Then, under the action of centrifugal force, the small particles are thrown out through the sieve holes 202 and fall on the top of the sieve plate 8. The large particles cannot pass through the sieve holes 202 due to their large volume and will remain inside the sieve cylinder 201 and be crushed by the crushing mechanism 3 until they can pass through the sieve holes 202, thereby improving the utilization rate of large drug particles.

[0024] As Figure 3As shown, a fixing plate 207 is fixedly installed inside the cylinder body 1. An empty groove is formed at the top of the fixing plate 207. The fixing plate 207 is sleeved on the surface of the sieve cylinder 201. An annular groove 208 is formed on the inner wall of the empty groove of the fixing plate 207. An annular plate 206 is fixedly installed on the outer surface of the sieve cylinder 201, and the annular plate 206 is located inside the annular groove 208.

[0025] The effects achieved by the above components are as follows: By setting the annular plate 206, the fixing plate 207 and the annular groove 208 to cooperate with each other for installing and limiting the sieve cylinder 201, the stability of the sieve cylinder 201 during rotation is improved. When the sieve cylinder 201 rotates, the sieve cylinder 201 drives the annular plate 206 to rotate, so that the annular plate 206 rotates inside the annular groove 208, and the annular groove 208 plays a role in supporting and limiting the annular plate 206, thereby improving the rotation stability of the sieve cylinder 201.

[0026] As Figure 4 shown, the crushing mechanism 3 includes a mounting frame 301. The mounting frame 301 is fixedly installed on the top of the cylinder body 1. A second motor 302 is fixedly installed on the top of the mounting frame 301. A rotating rod 303 is fixedly installed at the output end of the second motor 302. Uniformly distributed crushing rods 304 are fixedly installed on the surface of the rotating rod 303, and the crushing rods 304 are located inside the sieve cylinder 201.

[0027] The effects achieved by the above components are as follows: By setting the mounting frame 301 to support and install the second motor 302, the use stability of the second motor 302 is improved, and further the stability of the rotating rod 303 and the crushing rods 304 during rotation is improved. Under the action of the second motor 302, the rotating rod 303 is driven to rotate, and then the rotating rod 303 drives the crushing rods 304 to rotate. The crushing rods 304 crush large-particle drugs, making the large particles become small particles with qualified particle sizes, and improving the utilization rate of large particles.

[0028] As Figure 1 shown, a collection box 6 is arranged inside the base 4, and the collection box 6 is located directly below the cylinder body 1.

[0029] The effects achieved by the above components are as follows: By setting the collection box 6 to collect the drug particles discharged from the bottom of the cylinder body 1.

[0030] As Figure 1 shown, sliding grooves 7 are formed on both sides of the inner cavity of the base 4. Sliders are fixedly installed on both sides of the collection box 6, and the sliders are located inside the sliding grooves 7.

[0031] The effects achieved by the above components are as follows: By setting the sliding grooves 7 and the sliders to cooperate with each other for positioning and installing the collection box 6, preventing the collection box 6 from being installed offset, resulting in the collection box 6 not being directly below the cylinder body 1, and further causing the drug particles not to accurately fall inside the collection box 6.

[0032] The working principle of the fine filtration device for drug preparation:

[0033] The first motor 204 drives the driving gear 205 to rotate. Then, the driving gear 205 drives the convex teeth 203 to rotate, and the convex teeth 203 drive the screen cylinder 201 to rotate. The rotation of the screen cylinder 201 rotates the drug particles inside the screen cylinder 201. Then, under the action of centrifugal force, the small particles are thrown out through the screen holes 202 and land on the top of the screen plate 8. The large particles, due to their large volume and inability to pass through the screen holes 202, will remain inside the screen cylinder 201 and be broken by the breaking mechanism 3 until they can pass through the screen holes 202. Under the action of the second motor 302, the rotating rod 303 is driven to rotate. Then, the rotating rod 303 drives the breaking rod 304 to rotate, and the breaking rod 304 breaks the large-particle drugs, making the large particles into small particles with qualified particle sizes and improving the utilization rate of the large particles.

[0034] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is impossible to list all the implementation manners here. All obvious changes or variations derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
