Design and application of the medium draining screen's screenplate detachment detection device
WANG Meng
Abstract：The trouble with the operation of the medium draining screen in coal preparation plant is that the falling-off of its screenplate is unable to be timely detected,and there exists severe time delay in loca-ting the faulty plate through patrol inspection in a traditional manner.To address this issue,a screenplate dropping-off detection device is specifically designed based on analysis of the faulty plate detection tech-nologies currently available,and the working principle of the vibrating-rod-type level monitor,providing a new technical scheme capable of giving early warning of blockage of medium system by material.Practice shows that the device can be adjusted flexibly according to working conditions;and it works remarkably well with anti-clogging,impact-resistant and material sticking or gripping prevention capacities.Its other attractions include easy installation and routine maintenance,low fabrication cost,high working sensitivi-ty and reliability.
