摘要
A vibration feeder is a piece of equipment for rationing and conveying powder,particle and block materials.In order to test the regeneration performance of de-dusting medium for high-temperature coal gas,a set of de-dusting medium-feeding systems was designed quantitatively.The de-dusting medium-feeding system is used in the gasification process for cleaning coal gas.The system is mainly composed of a hopper unit,control unit and feeding unit.In order to optimize the feeding stability of the coal-gas dust-removal medium vibration feeding system,the setting and scope of the following design factors and operating factors are investigated.Specifically,it includes the influence of gate-valve-opening adjustment of the control unit on the feeding stability of a vibrating feeding system;the influence of the gap size of the dipleg of the control unit on the feeding sensitivity of the vibration system;the influence of the particle size of the de-dusting medium on the operating range of the vibrating feeding system;the influence of the digitization of the working-current indicator of electromagnetic vibrating feeders on measurement variation and the process variation of a vibration feeding system.This vibration feeding system can realize the function of precise and quantitative feeding of the de-dusting medium,which can meet the design requirements of subsequent experimental research.
