Scraping mechanism of centrifugal machine

Abstract

The invention discloses a scraping mechanism of a centrifugal machine. The scraping mechanism comprises a scraping plate and a scraping knife shaft, wherein the scraping plate is a vertically arrangedrectangular plate; one side, in the length direction, of the scraping plate is connected to the lower part of the scraping knife shaft; the lower side of the scraping plate is provided with a plurality of through slots which are formed in a spaced mode in a length direction of the scraping plate; an L-shaped rod is arranged on a position, above each through slot, at one side in the thickness direction of the scraping plate, and the L-shaped rod is composed of a horizontal part and a vertical part which are connected end to end, one side, away from the vertical part, in the length direction ofthe horizontal part is connected to the scraping plate, one side, away from the horizontal part, in the length direction of the vertical part vertically downwards extends, and the lower side of the vertical part is flush to the lower side of the scraping plate. The scraping mechanism can automatically perform scraping operation after centrifugal operation is accomplished; moreover, after scrapingis accomplished, solid-phase materials are directly crushed, stirred and dissolved in a rotary drum, and the materials do not need to transfer, so that operation steps can be simplified, efficiency is improved, and cost is reduced.

Description

technical field [0001] The invention relates to a centrifuge scraping mechanism. Background technique [0002] After centrifugation in the field of pharmaceutical processing, the liquid phase will be extracted by the liquid pumping device, and the remaining solid phase materials will stick to the inner wall of the centrifuge drum. Now there is generally a scraping step. The scraping step is to use Manually scrape the solid phase material from the inner wall of the drum into the drum, then transfer it to other containers to add solvent, and manually crush and stir to dissolve it. The obtained solution can be used for other purposes or subsequent processing. [0003] This traditional method is not only laborious but also inefficient by manual scraping. In addition, due to the need to transfer the solid-phase material between two containers, the steps are more complicated and the efficiency is not high, and bacteria and impurities are easily mixed during the transfer process, w...

[0003] This traditional method is not only laborious but also inefficient by manually scraping materials. In addition, due to the need to transfer solid-phase materials between two containers, the steps are more complicated and inefficient, and bacteria and impurities are easily mixed in during the transfer process, which does not meet the requirements GMP requirements
