The invention relates to the technical field of valve control, in particular to a pulverized coal anti-blocking device and method. Comprising a shell; the anti-blocking flashboard is arranged in the shell in a penetrating manner, one end of the anti-blocking flashboard is arranged outside the shell, and the other end of the anti-blocking flashboard is arranged in the shell in a penetrating manner; the sealing piece is arranged at the lower end of the shell, and the sealing piece is used for sealing the anti-blocking device; the valve seat is arranged at the lower end of the shell, and an inclined opening is formed in the bottom of the valve seat. By means of the improved design, when the valve device is closed, if a small amount of pulverized coal is accumulated in the sealing groove in the bottom, the pulverized coal can exist in the groove in the bottom to achieve the sealing effect, and if a large amount of pulverized coal is accumulated, the pulverized coal can be extruded to the outlet through the channe
