【摘要】：为了明确螺旋分选机的应用现状及优化手段,整合了螺旋分选机在我国的应用情况,分析了煤用螺旋分选机在应用中存在的问题;概括了螺旋分选机设备的优化手段,提出了煤用螺旋分选机的优化方向。结果表明:相对于非煤用螺旋分选机,煤用螺旋分选机距径比更小,分选圈数更多,多应用于动力煤选煤厂和可选性较好的炼焦煤选煤厂;目前煤用螺旋分选机存在分选密度较高、处理量较低、缺乏灵活性等问题;螺旋分选机的优化主要有改变结构参数和引进外力两种手段,在优化时应以改变结构参数为主,尽量保留螺旋分选机结构简单、无动力部件等特点。
[Abstract]:In order to clarify the application status and optimization means of spiral separator, the paper integrates the application of spiral separator in our country, analyzes the problems existing in the application of spiral separator for coal, and summarizes the optimization means of spiral separator equipment. The optimization direction of screw separator for coal is put forward. The results show that the ratio of distance to diameter is smaller and the number of separation cycles is more than that of non-coal spiral separator, and most of them are used in thermal coal preparation plant and coking coal preparation plant with good separability. At present, the spiral separator for coal has some problems such as high separation density, low handling capacity and lack of flexibility, and the optimization of the screw separator mainly includes changing the structural parameters and introducing external forces, and changing the structural parameters should be the main method in the optimization. As far as possible to retain the helical separator simple structure, no power components and other features.
