Star type unloading valve blanking blowout prevention and early warning device

Abstract

This utility model discloses a rotary ash discharge valve anti-spraying and early warning device, including two sets of side baffles arranged parallel to each other. One end of each set of side baffles is fixedly installed at the discharge port of the rotary ash discharge valve. A pressure plate is rotatably installed above the discharge port of the rotary ash discharge valve between the two sets of side baffles. A movable baffle is rotatably installed on the pressure plate downstream along the discharge direction. The two sets of side baffles are movably connected to the upper part of the pressure plate through a first adjusting cylinder. The advantage of this utility model is that it can stop the ash hopper discharge in time and issue an alarm when the ash hopper discharge is too large. It solves the problem that dust spray from the dust hopper cannot be detected in time under the existing technology. It can control the fluctuation of ash hopper discharge more timely, avoid the expansion of the impact of dust spray, and prevent production fluctuations, quality fluctuations, environmental hazards, and even safety accidents.
