| Heat-resisting slag vibratory conveyor (HSVC) was based on the theory of mechanical vibration principle and heat transfer conduction, which development and application in the conveyor equipment of steel heat-resisting slag. It belonged to high temperature vibratory mechine. In order to improve its safety and reliability, it was necessary to consider the strength of vibratory coveyor, dynamic characteristics and high temperature performance. This was of great theoretical significance and practical value to design, manufacture and application of vibratory conveyor equipment.This paper mainly reviewed the research status and development of vibratory conveyor firstly. Then the structural characteristics and operating principle of HSVC were introduced. Using ProE software to establish finite element model and the whole system simulation projects are completed in APDL command stream with ANSYS. The vibratory conveyor mainly analysis included static structural strength, steady-state response, coupling strength of thermal-fluid-solid, and explored water conservation of vibrating water-channel board.In terms of static structural statics, mainly analysis the structural strength of vibratory conveyor under stationary state and the result was far less than the yield strength of material. The structural deformation of vibratory conveyor was under the elastic deformation ranging.In terms of structural dynamics, modal analysis concluded that the first-eight frequency and the expansion of modal characteristics and verified the vibratory conveyor under operating frequency can be safety avoided the resonance region. Through steady-state response analysis under sine excitation of vibratory conveyor, this paper obtained amplitude-frequency response of the key location nodes and corresponding stress response. At the same time, this paper obtained maximum dynamic-stress response of key structural location on vibratory conveyor, which met the safety requirements.In terms of coupling strength of thermal-fluid-solid, this paper mainly analysis the coupling strength of vibratory water-channel board under temperature load, pressure load and structure load, which was the main bearing load structure of vibratory conveyor. Through the fluid flow and heat transfer analysis, it was shown the interface pressure distribution of heat-resisting slag, cooling water with the vibratory water-channel board and its temperature distribution. In order to prevent the high temperature water to producing water vapor, it was necessary to analysis the cooling water temperature distribution in vibratory water-channel board at steady state. Transfer the temperature distribution of vibratory water-channel board and the interface pressure distribution to structural strength analysis, considered the influence of structure load at the same time. The analysis result shown that this coupling strength of the vibratory water-channel board met the production requirements.In terms of water conservation, through analysis the influence of different flowing channel structures for heat dissipation and improved the typical locality structure of vibrating water-channel board. The result shown that appropriate adjustment fluid inlet-velocity can achieve similar cooling effection, so as to realize the purpose of water conservation. |
