Normal-temperature automatic mixing device for high-viscosity liquid

Abstract

The invention relates to a normal-temperature automatic mixing device for high-viscosity liquid, and belongs to the technical field of micro-fluidic control. The automatic mixing device comprises a sample feeding channel, a sample discharging channel, a fixing screw, an upper cover plate, a lower cover plate, a sealing gasket, a sample feeding transverse channel, a sample discharging transverse channel, a cavity and a magnetic body. After entering the closed cavity at a constant flow rate, various high-viscosity liquids are quickly stirred and mixed into a mixed solution under the action of the magnetic body rotating at a high speed, and the mixed solution is automatically discharged out of the cavity under the extrusion of the liquid in the cavity. According to the device, through an active mixing mode, a solution containing the magnetic body generates a bent motion trail under the action of magnetic field force, so that the contact area of the solution containing the magnetic body and another solution is increased, and the two solutions with relatively high viscosity are rapidly and uniformly mixed; the device is sealed through screws and can be flexibly disassembled, so that theuse cost of the device is reduced; and a plurality of devices can be connected in series to achieve an ideal mixing degree.

Description

technical field [0001] The invention relates to an automatic mixing device for high-viscosity liquid at normal temperature, belonging to the technical field of microfluidics. Background technique [0002] Under macroscopic conditions, the mixing of two solutions can achieve the purpose of uniform mixing of various solutions through mechanical stirring or hydrodynamic conditions. However, the mixing of macroscopic fluids requires a large amount of sample, and the mixed solution has a long residence time during the mixing process. If the mixed solution is an unstable solution, it is easy to change the properties of the solution during the mixing process, such as increased viscosity, which affects the mixing of macroscopic fluids. [0003] In a microchannel, the movement of the fluid is generally considered to be in a laminar flow state due to the relatively small Reynolds number. This means that the mixing of various liquids in the microchannel is mainly completed by the dif...
