Flow blocking device of gravity dust collector

The utility model discloses a flow blocking device of a gravity dust collector, and belongs to the technical field of gravity dust collectors. The shell is provided with a hollow cavity, an air inlet pipe is arranged on the shell, the lower end of the air inlet pipe is a horn mouth, an air outlet pipe and a baffle are transversely arranged on the side face of the upper end of the shell, the baffle is arranged at the bottom of the hollow cavity, the baffle is in a cone shape with an upward opening, and a discharging opening is formed in the bottom of the baffle. According to the flow blocking device of the gravitational dust collector, through the conical baffle arranged in the lower cavity, direct impact of airflow on the position where the particle impurities are accumulated on the lower portion is blocked, larger dust is prevented from being raised, and the effect of preventing the accumulated particle impurities from being blown by the air is achieved. 本申请公开了一种重力除尘器挡流装置，属于重力除尘器技术领域。壳体，该壳体具有一中空腔室，壳体上设置有入风管，
