Description

Water beam sealing device of step heating furnace Technical Field The utility model relates to the technical field of water beam devices, in particular to a water beam sealing device of a stepping heating furnace. Background The water beam sealing device of the step heating furnace is an important component part of the heating furnace, is mainly used for supporting and transferring steel billets, plays roles of cooling and protecting at the same time, and particularly, absorbs heat absorbed by the water beam in a high-temperature environment by utilizing the gasification cooling principle of water by introducing a cooling medium, usually saturated water, into the water beam to change the water into a steam-water mixture, and then the steam-water mixture returns to a steam drum. The process effectively reduces the temperature of the water beam, prevents the water beam from being damaged due to overheat, and simultaneously ensures that the steel billet cannot cause quality problems due to overheat of the water beam in the heating process; after the step-by-step heating furnace is used, a certain cooling medium is reserved in the water beam to protect the water beam; However, the existing sealing structures of the medium injection port and the medium output port of the water beam adopt a single sealing structure, such as a flange sealing or a sealing cap sealing, however, when the sealing structure is separated from the medium injection port and the medium output port, the medium in the water beam can be directly discharged, and the existence of the flow is inconvenient for a worker to connect the medium input part and the recovery part with the medium injection port and the medium output port, and meanwhile, the single sealing structure is easy to generate damage or liquid leakage phenomenon due to overheat of the water beam. Disclosure of utility model In order to solve the above problems, the present utility model proposes a water beam sealing device of a step-type heating furnace to solve the above problems more precisely. The utility model is realized by the following technical scheme: The utility model provides a water beam sealing device of a step heating furnace, which is characterized by comprising a frame body, a plurality of fixed water beams arranged in the frame body, a movable water beam arranged in the inner side of the frame body and positioned between the two fixed water beams, wherein the movable water beams are provided with a plurality of movable water beams, the bottom ends of the plurality of movable water beams are connected with a translation frame, the fixed water beams and the movable water beams are respectively provided with a cooling medium injection opening and a cooling medium output opening, sealing pieces are respectively arranged on the cooling medium injection opening and the cooling medium output opening, the bottom ends of the sealing pieces are in threaded connection with a sealing cover, the sealing pieces comprise an outer cover connected with the cooling medium injection opening and the cooling medium output opening, a conical table arranged in the outer cover and positioned below the outer cover, an annular body arranged in the outer cover and positioned above the outer cover, a retainer is arranged on the inner side of the annular body, a circulation gap is reserved between the retainer and the annular body, the inner side of the retainer is provided with a reset spring, and the retainer is connected with the reset spring.
