机采棉清杂系统的钉床式荷电装置与试验

针对机采籽棉清杂工序中荷电效果不佳的现实问题,提出了一种钉床式荷电方法。以MCU为主控制单元,设计了一款钉床式荷电控制系统。在荷电极板面上均匀分布且垂直于极板面的长度为5cm的金属钉,控制器控制静电发生器产生高压静电,通过荷电极板上的金属钉放电,将平铺在极板间的机采棉荷电。试验结果表明:与无金属钉的荷电极板相比,机采棉荷电均匀,荷电速度提高了8%,效果良好。该研究可为机采棉静电清杂应用提供参考。

Design and Experiment of the Type Bed of Nails of Charged Equipment of Machine-harvested Cotton

Aiming at the problem of real machine harvested cotton cleaning process of charging effect , put forward a type of nail bed charge method .With MCU as the main control unit , the design of a nail bed type charge control system .In the bearing surface of an electrode plate of the uniform distribution and the vertical plate surface has a length of 5 cm met-al nail , the controller controls the electrostatic generator to generate a high-voltage electrostatic , through pin bearing e-lectrode plate metal discharge , will tile the plate between the machine pick up cotton charged;test results show that com-pared and no metal nail charged plate , machine pick up cotton charged uniformly , charging speed increased by 8%, the effect is good;the study can machine pick up cotton electrostatic cleaning can be used as a reference .
