Medicinal solid screening device for removing metal powder

Abstract

The invention discloses a medicinal solid screening device for removing metal powder. The medicinal solid screening device comprises a device body, wherein a cavity is formed in the device body, a third-stage screening mechanism is arranged in the cavity, the three-stage screening mechanism moves up and down in the cavity through a transmission mechanism, the third-stage screening mechanism is used in cooperation with the transmission mechanism, and the transmission mechanism can drive the three-stage screening mechanism to move up and down, so that the manual shaking action of a professionalpharmacist is simulated, and the discharging quality of the three-stage screening mechanism is high; and first openings are formed in the two sides of a surrounding frame plate in a penetrating mode,and the left end and the right end of a first pharmacopeia screen are respectively inserted into the two first openings, a second pharmacopeia screen is arranged below the first pharmacopeia screen, and after being screened, coarse materials are located on the first pharmacopeia screen, medium materials are located on the second pharmacopeia screen, and fine materials are located in a material receiving tray, and the first pharmacopeia screen, the second pharmacopeia screen and the material receiving tray form a three-stage material distribution.

Description

technical field [0001] The invention relates to the related technical field of pharmaceutical equipment, in particular to a pharmaceutical solid screening device for removing metal powder. Background technique [0002] At present, in the field of pharmaceuticals, there are particle size requirements in the statutory standards for solid granules, powders, granule tablet intermediate product granules, and capsule filling granules, which require uniform particle size. In the process of making soft materials from granules, traditional metal screens are used for granulation, and occasionally the screens will be worn and broken, resulting in some metal particles and wires being brought into the granules, which has the following disadvantages: [0003] 1. After the granulation, the rotary vibrating sieve will be used for granulation, and the current rotary vibrating sieve equipment cannot remove the metal particles and wires produced in the previous process, so the metal particles ...

AI Technical Summary

Problems solved by technology

[0003] 1. After the granulation, the rotary vibrating sieve will be used for granulation, and the current rotary vibrating sieve equipment cannot remove the metal particles and wires produced in the previous process, so the metal particles and wires will bring patients to safety hazards;

[0004] 2. Due to design problems, the commonly used rotary vibrating screens in the market are inconvenient
