Many emerging novel materials are prepared by utilizing some motion characteristics of liquid drops on the surface of an object, such as non-stick shoes, anti-fog glass, non-stick ties and the like. One of the main ways to control the movement of the liquid drop on the surface of the object is to drive the liquid drop to directionally move on the surface by utilizing the difference of the hydrophilicity and hydrophobicity of the surface of the object to the liquid drop. The preparation of the surface with the difference between hydrophilic and hydrophobic properties needs to be carried out by mixing the hydrophilic material and the hydrophobic material in different proportions, so that the hydrophilic and hydrophobic materials need to be separated firstly, and an accurate and efficient separation device is needed.

The distance between the tops of the adjacent fishing arms is equal to the distance between an antinode and a node of the water surface in the vibration table during vibration. Each fishing arm is rotated out of the water to just reach the position of an antinode or a node of the water.

For example, from the last fishing arm to the next fishing arm, the time required is 10/6 seconds calculated according to the rotation speed of 6 r/min. The advancing distance of the guide rail in the period is 1.5 cm, which is just the distance from the center of an antinode to a node, so that the fishing arms can timely catch up to the area where particles are gathered for fishing when water flows out.

Under the influence of the micro particles on the water surface and the action of surface tension, compared with hydrophilic particles, the hydrophobic particles are smaller in volume and more influenced by gravity, and can move towards the center of an antinode under the water surface swing above and below the antinode. The hydrophilic particles can move away from an antinode, namely close to a node, the hydrophobic particles can gather at the antinode, the hydrophilic particles gather at the node, and the hydrophilic and hydrophobic particles are sequentially arranged on the water surface at intervals to form initial separation of spatial positions.

And the hydrophilic particles cannot enter the hollow shaft due to the closed reason of the arc-shaped sealing strip, and reach the rear part of the device along with the rotation of the fishing arm and fall into the water again under the action of gravity. The forward moving speed of the sliding block on the guide rail is matched with the rotating speed of the fishing arms, so that each fishing arm can be timely found in a particle gathering area, and only one type of particles can be fished. Meanwhile, as the fishing arms are even, the opening fishing arms are ensured to only fish the hydrophobic particles and collect the hydrophobic particles in the hollow shaft, and finally the separation of the hydrophilic and hydrophobic particles is realized.
Compared with the prior art, the invention has the advantages that: the invention discloses a device for separating hydrophilic and hydrophobic particles by utilizing water surface vibration for the first time. The advantages are as follows:
