Description

technical field [0001] The invention relates to the related technical field of separation equipment for chemical product preparation, in particular to a centrifugal separation device. Background technique [0002] During the preparation process of some chemicals, the components in the solution need to be separated by means of a centrifugal separation device, and the centrifugal separation mainly uses the characteristics of different specific gravity among the components to separate the components. [0003] Small doses of chemicals are often placed in test tubes, and the test tubes are directly placed on the centrifugal separation device for separation during centrifugation. However, the number of test tubes that can be placed in the existing separation device is small, so the centrifugal separation efficiency is low.

Problems solved by technology

[0003] Small doses of chemicals are often placed in test tubes, and the test tubes are directly placed on the centrifugal separation device for separation during centrifugation. However, the number of test tubes that can be placed in the existing separation device is small, so the centrifugal separation efficiency is low. At the same time, For some centrifugal separation devices, after the centrifugal movement is completed, it is easy to cause the breakage of the test tube, and it is inconvenient to place multiple test tubes in the centrifugal separation device

[0004] During the separation process of large doses of chemicals, the components cannot be finely screened according to the particle size between different components. After the centrifugation is completed, it is necessary to sieve the components of different particle sizes, which reduces the centrifugal separation. At the same time, the existing centrifugal separation device directly discharges the solution through the drain pipe. On the one hand, this discharge method increases the pollution of the reusable solution, and at the same time analyzes the unseparated components in the solution.
