Problems solved by technology

However, the research and development of inclined water simulation experimental devices in China is not enough. Some existing inclined water simulation experimental devices are not completely similar, resulting in a large error between the test results and the actual data. Specifically, Domestic inclined water simulation experiment devices have the following deficiencies:
[0003] 1. It does not have the function of adjusting the inclination angle of the rotating shaft in the container;
[0004] 2. The physical scene where gas is radially injected into water through the impeller nozzle to form bubbles cannot be realized;
[0005] 3. The gas flow and the distance between the impeller and the bottom of the barrel cannot be adjusted precisely;
[0006] 4. It does not have the function of programming to control the rotor speed, steering, and running time
[0007] The above deficiencies directly affect the reliability of the gas-liquid two-phase flow test results under specific conditions (rotation axis tilt), which in turn restricts the improvement of aluminum alloy refining and purification process

Abstract

The present invention relates to an inclined water simulation experiment device and an experiment method thereof in the process of purifying aluminum melt. Body, transparent container and PLC single-chip microcomputer used to control the transmission components. This method uses clarified water as the medium to simulate the aluminum alloy melt, and selects a transparent acrylic square bucket as the container for the water medium. The evolution process of the furnace realizes the simulation of the purification process in the furnace or on-line, and achieves a completely similar degree through the adjustment of the inclination angle. Through the simulation experiment carried out by the method of the present invention, it is possible to visually observe and record the flow field velocity distribution, bubble distribution and size in the transparent container, and finally realize the gas-liquid two-phase analysis of the opaque aluminum alloy melt under specific process conditions (for example: the shaft is inclined) Accurate prediction of the flow field.
