Description

Technical Field

[0001] The utility model belongs to the field of granule screening, and particularly relates to a rapid screening device for granule finished products. Background Art

[0002] Granules refer to dry granular preparations made by mixing active pharmaceutical ingredients and suitable excipients with a certain particle size. Unless otherwise specified, the sum of the coarse particles larger than the first sieve (2000 μm) and the fine particles smaller than the fifth sieve (180 μm) in the granules does not exceed 15%. When preparing granules, in order to ensure the uniform size of the granules, a corresponding screening device is needed to screen the finished granules, so that the larger granules can be screened out for subsequent packaging and storage. However, when the existing screening device is in use, due to the lack of an effective diversion structure, the unqualified granules after screening still remain on the sieve mesh, and at this time, manual cleaning is required, which has limitations.

The main body of the support 1 has a one-way open structure at the top end. And an electric push rod 101 is installed on the top surface of the horizontal member in the support 1, and the electric push rod 101 is perpendicular to the support 1. The top end of the electric push rod 101 is the output end, and a plug plate 102 is installed on this output end. The main body of the plug plate 102 is circular, and the plug plate 102 is used to close the bottom opening of the screen 204. The electric push rod 101 and the plug plate 102 together form a closed structure. The bottom end of the motor 301 is installed with an output shaft, and a mounting seat 302 is installed on this output shaft. The main body of the mounting seat 302 is circular, and the diameter of the mounting seat 302 is smaller than the diameter of the bottom opening of the screen 204. The gap between the mounting seat 302 and the screen 204 is used for the granule to pass through. And a scraper 303 is fixedly connected to the outer peripheral surface of the mounting seat 302. The scraper 303 is of an inclined structure and is in contact with the inner wall of the screen 204. And there are four scrapers 303 in total, and the four scrapers 303 are fixedly connected to the outer peripheral surface of the mounting seat 302 in an annular array.

[0023] See Figure 2 、 Figure 3 andFigure 4 , an aggregate tray 2 is fixedly connected to the inner side of the support 1. The main body of the aggregate tray 2 is a top-unidirectional opening structure, and a support base 201 is fixedly connected inside the aggregate tray 2. The main body of the support base 201 is an annular structure, and the diameter of the support base 201 is smaller than the diameter of the aggregate tray 2. A through groove is formed at the front end of the outer peripheral surface of the aggregate tray 2, and a discharge pipe 202 is fixedly connected inside the through groove. The discharge pipe 202 communicates with the aggregate tray 2, and a seat body 203 is fixedly connected to the top surface of the support 1. The main body of the seat body 203 is an annular structure.

[0024] See Figure 2 , a sieve mesh 204 is fixedly connected inside the seat body 203. The sieve mesh 204 is a frustum-shaped structure that is thicker at the top and thinner at the bottom, and through holes are formed in an annular array inside the sieve mesh 204.

At this time, then put the granules to be screened into the inner position of the sieve mesh 204 through the top opening of the seat body 203. Then, start the motor 301 installed on the top surface of the installation frame 3 to drive the rotation of the installation seat 302 and the scraper 303, so that the granules entering the sieve mesh 204 can be rotated along the inner wall of the sieve mesh 204 by the scraper 303 to fully swing the granules entering the sieve mesh 204 to improve the screening efficiency;
