DEVICE TO PREVENT CLOGGING VERTICAL PIPE OF GRINDING MILL FOR DUST COAL

摘要

invention hopper with coal, the coal hopper coal to be transported to geuptan groups and intuition, as provided in the pulverized coal crushing mill including a mill for grinding coal is transported by said geuptan group and standpipe, is installed in the interior of the standpipe, but form the inner tube, a plurality of circular arc-shaped plate in combination with and consisting of split tube, and the crushing plate is installed to be attached to the inner surface of the divided tube, the installation to be connected in each demolition doedoe plate, and the movement is installed so as to divide the tube and standpipe through-shaft in turn, each of the moving axes installation is connected to the cylinder for moving the slide moving axis, characterized in that it comprises a vibration sensor which is provided in the standpipe. according to the invention, the crushed coal is automatically fixed to the pulverized coal crushing mill standpipe and by allowing you to wash, time-savers to remove the coal secured to the vertical pipe without causing disruptions in coal production, the worker does not remove manually fixed in advance for accidents and coal gas poisoning has the effect of preventing. ;
