【摘要】：为了增强双卧轴全尾砂膏体充填料搅拌机的搅拌效果,提高搅拌机生产能力,在前人研究的基础上,开展了“双卧轴全尾砂膏体充填料搅拌机叶片排列方式和叶片参数优化设计”课题研究,主要研究内容如下:(1)不同叶片排列方式的全尾砂膏体充填料搅拌机的搅拌效果仿真。分析比较了单向正排列、单向反排列和对称排列方式对搅拌机搅拌效果的影响,提出了一种新的叶片排列方式—混合排列方式,并对四种叶片排列方式的全尾砂膏体充填料搅拌机内部流速场进行仿真,根据仿真结果验证混合排列方式的优越性。(2)混合排列全尾砂膏体充填料搅拌机叶片参数优化。在叶片排列方式优化的基础上,对双卧轴全尾砂膏体充填料搅拌机叶片的两个主要参数(叶片宽度和安装角度)进行优化设计,提出叶片角度设计的约束条件和最合理的设计建议,以提高搅拌机生产能力。(3)叶片结构设计优化。通过对叶片结构模型的应力应变分析,优化叶片结构设计,对叶片结构设计的材质和结构形式提出建议。研究结果表明:混合排列方式的全尾砂膏体充填料搅拌机内部流场强度高,区域大,搅拌效果最佳;叶片宽度根据设备功率和生产能力要求确定,叶片角度最佳角度为49°;叶片的材质宜选择经济、耐磨的Q235。
[Abstract]:In order to enhance the mixing effect of the double horizontal shaft full tailing paste filling material mixer and improve the production capacity of the mixer, on the basis of previous studies, The research on the optimum design of blade arrangement and blade parameters of double horizontal shaft full tailing paste filling material mixer was carried out. The main contents are as follows: (1) the simulation of the mixing effect of the whole tailings paste filling mixer with different blade arrangement. This paper analyzes and compares the influence of unidirectional positive arrangement, unidirectional inverse arrangement and symmetrical arrangement on agitation effect of agitator, and puts forward a new arrangement mode of blade, that is, mixing arrangement. The flow field of four kinds of blade arrangement is simulated, and the superiority of the mixed arrangement is verified according to the simulation results. (2) the blade parameters of the mixed paste filling mixer are optimized. On the basis of the optimization of blade arrangement, two main parameters (blade width and installation angle) of double horizontal shaft full tailing paste filling mixer blade are optimized. The constraint conditions of blade angle design and the most reasonable design suggestions are put forward in order to increase the production capacity of mixer. (3) Blade structure design optimization. Through the stress and strain analysis of the blade structure model, the blade structure design is optimized, and the material and structure form of the blade structure design are suggested. The results show that the internal flow field intensity is high, the area is large and the mixing effect is the best, and the blade width is determined according to the requirements of equipment power and production capacity, and the optimum angle of blade angle is 49 掳. The material of blade should choose economy, wear-resistant Q235.
