Abstract

The invention relates to a slag sluice flap valve, which is mounted on a slag sluice so as to block and open the slag sluice. The slag sluice flap valve comprises an oil cylinder, an oil cylinder seat, a connecting rod, bearing seats, a valve plate, a bottom plate and a valve plate shaft, wherein the oil cylinder seat and the bearing seat are both fixed to the top of a groove, the oil cylinder is fixedly mounted on the oil cylinder seat, the two axial ends of the valve plate shaft are supported on the two bearing seats on the two sides in the width direction of the slag sluice correspondingly, the oil cylinder is in driving connection with the valve plate shaft through the connecting rod, and the valve plate is fixedly installed on the valve plate shaft, so that the oil cylinder can drive the valve plate to rotate along with rotation of the valve plate shaft. The bottom plate is embedded in the groove of the slag sluice, the bottom plate is provided with the sealing face extending out of the groove, and the sealing face of the bottom plate can be tightly attached to the sealing face of the valve plate so that the groove can be blocked. In this way, the problem that the sealing face of an existing slag sluice valve is prone to being corroded and abraded is solved.

Description

technical field [0001] The invention relates to the technical field of ironmaking blast furnace slag treatment, in particular to a slag flushing ditch flap valve. Background technique [0002] The red slag produced in the ironmaking blast furnace production process is generally quenched and cooled by slag flushing water, and then enters the water slag treatment system through the slag flushing ditch, such as sedimentation tanks, bottom filter tanks, etc. Most of the slag flushing ditches are equipped with multiple bifurcations, and each bifurcation is equipped with a valve. The slag outlet of each bifurcation corresponds to a sedimentation tank or bottom filter tank. During production, the valves of the slag flushing ditch are used to switch. Make water slag selectively enter the corresponding pool. [0003] The normal operation of the slag flushing ditch valve plays an important role in ensuring the timely treatment of blast furnace slag and the orderly production of the b...
