The invention belongs to the technical field of submerged arc furnaces, and particularly relates to an automatic pressure relief
system for a furnace cover of a submerged arc furnace. The automatic pressure relief
system for the furnace cover of the submerged arc furnace aims at the problems that the function of an existing furnace cover pressure relief device is single and the protection effect is poor, the following scheme is provided at present. The automatic pressure relief
system comprises a furnace cover body, wherein a sealing plate is fixedly connected to the upper surface of the furnace cover body, the upper surface of the sealing plate is provided with a protective cover, the inner surface of the sealing plate is movably connected to a pressure relief cover through a hinge, the upper surface of the
pressure release cover is fixedly connected to a
weight gain box, a
pressure release cavity is formed inside the furnace cover body, and a
locking plate is arranged at one end, away from the hinge, of the
pressure release cover. The pressure relief system has the functions of automatic pressure relief and the automatic reset of the pressure relief cover, the trouble of manual shutdown operation is avoided, the working efficiency is improved, a multi-point
temperature monitoring structure is added, so that people can know the temperature condition of furnace steam in the furnace cover in real time, meanwhile, the protective effect is good, and the safety of people can be guaranteed to the largest extent when needed.
