| dc.description.abstract | In today′s engineering industry, the storage tank plays a very important role, not only in storing the particles inside the container, but also in the discharge process of the tank is a very concerned issue in the industry, and in the discharge of the particles, the outlet size or the size of the particles often cause permanent blockage behavior, so that the outlet can not discharge the particles completely. In order to discharge the clogged particles at the outlet, the particles are often discharged smoothly and completely by manual knocking action, and this labor cost is a very troublesome problem in the engineering industry.
In the experiment of this thesis, a two-dimensional container was used as the base, and a long bar-shaped insert was placed above the internal outlet, and a vibrated plate was used to make it move vertically up and down, and a conveyor belt was set up below the outlet, so that the particles were smoothly transported into the container under the experimental equipment. In order to capture the internal flow phenomenon, a high-speed camera is used to take images of the discharge process, and the images are later analyzed by the particle tracking method to investigate the mass flow rate, the number of clogging times, and the clogging maintenance time.
After a series of analysis, it was found that the addition of vertical vibrated plate would indeed affect the overall discharge efficiency at different vibration amplitudes and frequencies.
In the subsequent analysis of the clogging behavior, the bridges were divided into the left and right halves of the bridges centered on the vertical vibrated plate. In order to know the structural properties of the left and right halves of the arch connected with the vertical vibrated plate, the arch were quantified by a linear regression and the angle between with the vertical vibrated plate was measured. Based on the results of the analysis, it was found that there was a strong correlation between the angle of the arch and the stability of the arch structure.
