Description

Distributed oscillation device

Technical Field

The utility model relates to a dispersion oscillation device, and belongs to the technical field of material dispersion mixing.

Background

The dispersion oscillation device is a machine for driving the sample to oscillate. There are generally two roles: one sample dispersion and one sample comminution. The use scenarios are:

1. the two incompatible liquids are fully contacted with each other along with the oscillation process of the dispersion oscillation device, so that the extraction process is quickened and the better extraction effect is achieved.

2. And (5) mixing solid and liquid. By the action of the dispersion oscillation device, the liquid and the solid can be fully contacted. The extraction or dissolution process is accelerated.

3. The solid was crushed. The dispersion oscillation device drives the solid to oscillate vigorously. The solid particles are collided with each other vigorously so as to achieve the purpose of crushing the solid particles.

The current common dispersion oscillation device on the market has two working modes of horizontal oscillation and vertical oscillation.

The horizontal oscillating machine is used for driving the container and the sample in the container to oscillate horizontally and rapidly in 8 shape. The solid or liquid in the container is driven by the dispersing and oscillating device to generate a movement similar to a vortex shape. May also be referred to as a vortex disperser.

The vertical oscillator drives the container and sample fixed on the dispersing machine to reciprocate vertically. The solid or liquid in the container is collided with in a vertical direction in the container by intense movement.

A disadvantage of horizontal dispersers is that the containers on the market are generally long cylindrical straight pipes. This means that the space for movement of the solid or liquid in the straight tube is relatively very limited if it collides with the horizontal movement. There is no way to disperse well for slightly viscous liquids or large particle solids.

The vertical disperser moves vertically back and forth. For long cylindrical straight tube containers, the movement space is relatively larger and the oscillation efficiency is higher. The problem that viscous liquid or large-particle solid cannot be dispersed in a horizontal dispersing machine can be effectively solved. However, the vertical dispersing machine on the market at present oscillates together at multiple stations, so that if the total weight of the sample and the weight of the oscillating arm driving the sample are heavy, the noise of the oscillating machine is very large and then the oscillating machine is not easy to fix due to inertia in the oscillating process. The failure rate is high.
