Description

Technical Field

[0001] The invention belongs to the technical field of particle screening, in particular to a particle screening device for preparing chitosan hemostatic powder. Background Art

[0002] Chitosan hemostatic powder is a commonly used hemostatic product. Its main ingredient is chitosan, a natural high-molecular compound extracted from the shells of crustaceans. Chitosan hemostatic powder can quickly come into contact with blood and coagulate into blood clots, thereby effectively controlling bleeding. Chitosan is a material with good biocompatibility and no toxic side effects on the human body. After the preparation of chitosan hemostatic powder, particle screening is a key step, which helps to ensure the uniformity of the particle size of the hemostatic powder product, thereby affecting its hemostatic effect and physical properties. Standard experimental sieves with different mesh sizes are usually used for screening. These sieves usually have 20 mesh, 40 mesh, 60 mesh, 80 mesh, 100 mesh and other specifications. The appropriate sieve can be selected for screening according to needs.

[0003] When in use, the drug powder particle screening devices in the prior art mostly use multi-layer screens to effectively screen the agglomerated particles in the drug powder particles.

The inner wall of the collecting barrel 13 is scraped and cleaned, so that the inner wall of the collecting barrel 13 is cleaned, and the cleaned solution flows out through the one-way pipe 21. After the cleaning is completed, the inside is dried by the drying blades 22, and the threaded ring 171 is limited by the screw rod 16. The connecting rod 172 drives the threaded ring 171 to move along the inner wall of the collecting barrel 13 through the threaded ring 171. The cleaning brush 173 is limited by a limiting groove that is matched with the size of the cleaning brush 173 on the inner wall of the collecting barrel 13, so that the cleaning brush 173 can only move up and down by the rotation of the screw rod 16. The bellows is compressed or stretched during the rotation of the threaded ring 171, and the particles can be prevented from being stuck in the thread groove of the screw rod 16 through the bellows.

[0049] The working principle and use process of the present invention:

[0050] First, the driving motor 6 drives the first transmission shaft 701 to rotate, the first transmission shaft 701 drives the first bevel gear 702 to rotate, the first bevel gear 702 meshes with the second bevel gear 703 and drives the second bevel gear 703 to rotate, the second bevel gear 703 drives the second transmission shaft 704 to rotate, the second transmission shaft 704 drives the rotating rod 8 to rotate, because the inner push plate 905 is limited by the limit block 906, the rotating rod 8 drives the rotating pin 901 to move, and the rotating pin 901 drives the first hinge seat 902 to move along the rod wall of the rotating rod 8;

[0051] When the rotating pin 901 moves along the rod wall of the rotating rod 8, the first hinge seat 902 drives the push rod 903 to move, and the push rod 903 pushes the inner push plate 905 to move along the surface of the screening plate 12 through the second hinge seat 904. At this time, every two adjacent outer push plates 909 hold each other, and the outer push plates 909 slide along the outside of the inner push plates 905. The limit spring 908 stretches and becomes longer, and the inner push plates 905 and the outer push plates 909 are fully extended to form a complete ring.

[0052] During the extension of the outer push plate 909 and the inner push plate 905, the outer push plate 909 and the inner push plate 905 push the particles on the surface of the sieve plate 12. After the outer push plate 909 and the inner push plate 905 are fully extended, the pushed particles fall from the side of the sieve plate 12 to the filter plate 11. At this time, the servo motor 14 drives the first fixed shaft 151 to rotate, the first fixed shaft 151 drives the first spur gear 152 to rotate, the first spur gear 152 meshes with the synchronous belt 153 and drives the synchronous belt 153 to rotate, the synchronous belt 153 meshes with the second spur gear 154 and drives the second spur gear 154 to rotate, the second spur gear 154 drives the second fixed shaft 155 to rotate, and the second fixed shaft 155 drives the screw rod 16 to rotate;

[0053] The screw 16 rotates and drives the water inlet pipe 19 to rotate. The water is sucked into the pipe by the water pump 18, and the water is diverted by the diverter pipe 20. The water flows out from the inside of the diverter pipe 20 to the outside. Since the water inlet pipe 19 drives the diverter pipe 20 to rotate, the water enhances the cleaning power during the process of the diverter pipe 20 rotating. The cleaned particles and water stains flow into the collecting barrel 13 through the sieve plate 12.

[0054] At this time, the screw rod 16 drives the threaded ring 171 to rotate, and the threaded ring 171 drives the cleaning brush 173 to move along the inner wall of the collecting barrel 13 through the connecting rod 172. At this time, the cleaning brush 173 scratches and cleans the inner wall of the collecting barrel 13, so that the inner wall of the collecting barrel 13 is cleaned, and the cleaned solution flows out through the one-way tube 21. After cleaning, the interior is dried by the drying blades 22 for next use, and the operation is completed.
