Abstract

The invention relates to an in-situ continuous separating device for magnetic medium particles, comprising a reactor, wherein the reactor is provided with a tank body, and a stirring paddle is installed in a central axis position in the tank body. The in-situ continuous separating device is characterized by also comprising a plunger-type in-situ continuous separating system; the plunger-type in-situ continuous separating system comprises a cylindrical sleeve with a sealed top, the bottom of the sleeve is fixedly arranged at the middle lower part of the side wall of the tank body and is communicated with the reactor, a cylindrical piston is nested in the cylindrical sleeve, and a ring magnet is sleeved outside the cylindrical sleeve; the upper part of the body of the sleeve is provided with a discharging hole on which a liquid valve is arranged; and the piston is connected with a crank connecting rod of a crank connecting rod mechanism through a fixed shaft sleeve, and the crank connecting rod penetrates through the top of the sleeve and drives the piston to reciprocate under the action of the crank connecting rod mechanism. The inner included angle between the sleeve and the tank body of the reactor ranges from 45 DEG to 70 DEG. The in-situ continuous separating device is simple in design and simple and convenient to operate.

Description

technical field [0001] The invention relates to a device for separating magnetic medium particles, in particular to a device for continuously separating magnetic medium particles in situ. Background technique [0002] With the development of material technology, the particle size of superparamagnetic particles can reach the micron or nanometer level, which has a large surface area and high surface activity. Therefore, it is thermodynamically unstable and easily aggregated into clusters. In order to prevent the coagulation between the magnetic particles and form a stable colloidal solution, the surface of the magnetic particles needs to be modified during the preparation process. The surface of the modified magnetic particles should have more active functional groups, such as -NH 2 , -COOH, -OH and -CHO, etc., in order to couple biomolecules and affinity ligands to obtain magnetic carriers suitable for various applications. The magnetic particles contain magnetic particles i...
