Medicinal solid screening device with three-stage screening mechanisms

Abstract

The invention discloses a medicinal solid screening device with a three-stage screening mechanism. The three-stage screening mechanism comprises a movable plate, a material collecting tray and a surrounding frame plate, wherein a first pharmacopeia screen mesh and a second pharmacopeia screen mesh are installed in the surrounding frame plate, the first pharmacopeia screen mesh and the second pharmacopeia screen mesh are distributed up and down, the mesh aperture of the first pharmacopeia screen mesh is greater than that of the second pharmacopeia screen mesh, and the surrounding frame plate islocated in the upper end of a cavity. According to the medicinal solid screening device with the three-stage screening mechanism, an auxiliary mechanism is located on the lower end of a transmissionround wheel, and the auxiliary mechanism is used for supporting the transmission mechanism, so that the rotation of the transmission round wheel is stable, and the use reliability of the medicinal solid screening device is high.

Description

technical field [0001] The invention relates to the related technical field of pharmaceutical equipment, in particular to a pharmaceutical solid screening device equipped with a three-stage screening mechanism. 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, s...

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 to replace the screens. At the same time, the quality of the screens is not high, and they do not have the function of multi-stage material distribution. The practicability is poor, and the noise of this equipment is relatively large. , causing a lot of interference to users, so we propose a pharmaceutical solids screening device with a three-stage screening mechanism to solve the above problems
