Description

Technical Field

[0001] The utility model relates to the technical field of dust removal equipment, in particular to a dust removal device for a pharmaceutical tablet press. Background Art

[0002] In the production process of solid pharmaceutical preparations tablets, a pharmaceutical tablet press is used. The pharmaceutical tablet press places granules or powdered medicine powder in the die holes and presses them into tablets by a punch. However, during the process of the medicine powder entering the tablet press for pressing, due to the vibration and transmission of the machine, a lot of dust is inevitably generated, and the surface of the tablet after pressing the medicine powder often adheres to powder. The diffusion of these pharmaceutical dusts into the air will cause pollution, and the diffusion of these pharmaceutical dusts will also cause material loss.

[0003] The existing pharmaceutical tablet presses usually prevent the diffusion of dust in a fully sealed manner, and then extract the dust gas in the pharmaceutical tablet press through a suction fan and a dust removal device to achieve the cleaning inside the pharmaceutical tablet press. The existing dust removal devices for pharmaceutical tablet presses are usually cabinet-type devices with multiple built-in filters. Although they can effectively filter dust, the exhaust speed is slow. The bag-type dust removal device usually only has a large vertical cloth bag, and the dust removal and exhaust areas are limited. Therefore, they will all affect the filtering efficiency of the dust gas in the pharmaceutical tablet press. For this reason, a dust removal device for a pharmaceutical tablet press is proposed.
