提出了一种使用介电泳力的颗粒分离器,以实现使用常规方法不能容易地进行的颗粒分离。所提出的分离器由堆叠的网状电极组成,高频AC电压施加到该网状电极。在这项研究中,碳化钨颗粒从混合物中分离出的颗粒作为一个例子,因为目前有一个新的方法来回收昂贵的钨合金颗粒从使用过的过滤介质在制造超硬加工工具的行业的需求。此外,提出了一个简单的模型来关联的实验结果,以便建议的分离器的特性,包括电压-频率的影响,可以计算。此外,提出了多级分离以实现高分离程度。优化的电压-频率和级数,以实现一个目标的分数可以确定使用本研究获得的分离特性的图。
A particle separator using dielectrophoretic force is proposed to enable particle separation that cannot be easily conducted using conventional methods. The proposed separator consists of stacked mesh electrodes to which high frequency AC voltage is applied. In this study, tungsten carbide particles were separated from a mixture with diatomite particles as an example because there is currently a demand for a new method to recover expensive tungsten alloy particles from used diatomite filter media in industries manufacturing super-hard machining tools. Additionally, a simple model to correlate the experimental results is proposed so that the characteristics of the proposed separator, including the influence of voltage-frequency, can be calculated. Moreover, a multistage separation is proposed to achieve a high separation extent. The optimized voltage-frequency and stage number to achieve a targeted fraction can be determined using a diagram of the separation characteristics obtained by this study.
