Abstract

The invention discloses a layering device and method capable of achieving multi-layer fluid, and belongs to the technical field of fluid experiment devices. The device comprises a water tank, a liftable layering partition plate mechanism and a control unit, a flow inlet is formed in the side wall of the water tank, a flow outlet is formed in the bottom of the water tank, the liftable layering partition plate mechanism comprises a mechanism supporting frame, a vertical lifting driving unit, a partition plate folding and unfolding driving unit and a flexible partition plate, and the flexible partition plate can transversely partition the water tank through a self-sealing partition plate channel to form a closed area. The control unit cooperates with all the components to act. The layering method comprises the steps that the partition plates are lowered to the preset height, the flexible partition plates are released for isolation, fluid with the corresponding density is injected, the partition plates are wound, and the multi-layer stepped layered structure (the density of each layer is distributed in a vertical gradient mode) can be prepared by repeating the circulation. Layered preparation time is shortened from several hours to dozens of minutes, interlayer interfaces are clear, full-process automation is achieved, the device is adaptive to experiments in multiple fields such as ocean engineering and fluid mechanics, and experiment repeatability and device universality are remarkably improved.
