AI Technical Summary

Technical Problem

Existing centrifuges have problems such as high energy consumption and poor separation effect when efficiently separating liquid mixing, especially when the rotation speed is high, which can easily damage the samples and increase the operating cost.

Method used

Multiple drum sleeve designs are adopted to achieve different levels of drum sleeve separation through opening and closing of the screen hole. Combined with a spiral flow stop plate with a shortened radius, the liquid mix is ​​evenly distributed, and the optimal centrifugal force for the liquid mix separation is calculated based on the position and median rotation speed of the optimal drum sleeve.

Benefits of technology

It realizes efficient and energy-saving liquid mix separation, improves separation efficiency and purity, reduces energy consumption, and enhances the flexibility and scope of application of the centrifuge.

Abstract

The invention discloses an operation state control method applied to a centrifugal machine. A rotating shaft is driven to rotate according to a rotating speed median value so that mixed liquid can be evenly distributed into each set of rotating drums; after separation of n parts of mixed liquid is completed, a set of rotary drums with the best separation effect in centrifugal separation of each set of rotary drums is confirmed, and the optimal centrifugal force of mixed liquid separation is obtained through calculation; calculating the radius of the energy-saving rotary drum to obtain a corresponding energy-saving rotary drum sleeve, and configuring the optimal rotating speed of the rotating shaft according to the position of the rotary drum sleeve and the optimal centrifugal force; and the mixed liquid is guided to the fixed drum sleeve. And driving the rotating shaft to rotate according to the optimal rotating speed, and separating the mixed liquid. Mixed liquid can be separated at the same time through multiple centrifugal forces. Through one-time separation of a plurality of rotary drum sleeves, the most suitable separation rotary drum can be determined at the fastest speed, and the separation efficiency is improved. And only one set of drum sleeve is used for separation again, so that the efficiency is high, and meanwhile, energy is saved.
