Abstract
The invention relates to a water-cooling quick-open manhole device for a flue type waste heat boiler. The water-cooling quick-open manhole device comprises a lower manhole cylinder. A lower flange is arranged on the lower manhole cylinder. The two upper ends of the lower flange are respectively provided with at least one fixing lug plate. An upper manhole cover plate is fixedly connected to one fixing lug plate through a right angle rotary arm. Pull rods are fixedly connected to the fixing lug plates on the other side. The upper ends of the pull rods penetrate through fixing holes in the upper manhole cover plate and fix the upper manhole cover plate through fixing devices. The lower manhole cylinder and the upper manhole cover plate are both of inner-outer ring interlayer type structures. A cover plate water inlet and a cover plate water outlet are formed in an interlayer of the upper manhole cover plate. Baffling partition plates are arranged in the interlayer of the upper manhole cover plate. According to the water-cooling quick-open manhole device for the flue type waste heat boiler, the service life of the quick-open manhole device is effectively prolonged, the yellow smoke and dust overflow phenomenon caused by manhole burn-through is avoided, and the labor manpower for maintaining the quick-open manhole device is greatly relieved. The combined structure of the design is convenient to assemble and disassemble and high in applicability.
Description
Technical field
The present invention relates to a kind of flue type waste heat boiler steelmaking equipment, specifically a kind of device of water-cooled quick opening manhole for flue type waste heat boiler.
Background technology
On steelmaking equipment, flue type waste heat boiler is installed on converter evaporation cooling air flue with water-cooled quick opening manhole device, is positioned at stage casing and three curved, four crooks of flue, its objective is the device for deashing, scarfing cinder or maintenance use in flue.Whether manhole device's design and use are reasonable, directly affect temperature and environment in steelshop, affect the rhythm of production of factory.If manhole device design is good, also can alleviates workman's switch manhole and safeguard the workload of manhole.
The manhole device of steel mill use is generally flange bolt fastening mostly at present, the anti-material of the inboard cast of upper cover plate, and some steel mills adopt the mode of the embedded fire-resistant cotton of cover plate; Yet in actual use procedure, the anti-material that mostly occurs comes off, fire-resistant cotton comes off, thereby cover plate is burnt by high-temperature flue gas, or the phenomenons such as weld cracking that the manhole cylindrical shell is connected with flue occur; Finally cause when bessemerizing, a large amount of tobacco and flare emit from burning, outside cracking, and it is severe that site environment becomes; Because the problems referred to above often appear in manhole, cause the workman to increase the maintenance workload of manhole simultaneously, it is large that the labour intensity of high temperature service becomes.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the shortcoming of prior art, provides a kind of reasonable in design, simple in structure, and the flue type waste heat boiler of good sealing effect and long service life is with water-cooled quick opening manhole device.
In order to solve above technical problem, the invention provides a kind of flue type waste heat boiler water-cooled quick opening manhole device, comprise the manhole lower shell, described manhole lower shell is provided with lower flange, on described lower flange, two ends at least respectively are provided with a fixedly otic placode, and one of them fixedly is fixed with the manhole upper cover plate by the right angle pivoted arm on otic placode, and opposite side fixedly is fixed with pull bar on otic placode, and the fixing hole on the manhole upper cover plate is passed in described pull bar upper end, and by the fixing manhole upper cover plate of fixture; Described lower shell and manhole upper cover plate are the Internal and external cycle sandwich type structure, and described manhole upper cover plate interlayer is provided with cover plate water inlet and cover plate delivery port, are provided with the baffling dividing plate in described manhole upper cover plate interlayer.
The technical scheme that the present invention further limits is: aforesaid flue type waste heat boiler is with water-cooled quick opening manhole device, and the fixture of pull bar upper end comprises wedge, the rectangular opening be complementary with wedge that described wedge passes the pull bar upper end.
Further, aforesaid flue type waste heat boiler water-cooled quick opening manhole device, described baffling dividing plate is three, and is the dislocation placement.
Further, aforesaid flue type waste heat boiler, with water-cooled quick opening manhole device, is provided with the asbestos layer of cloth between described lower flange and manhole upper cover plate.
Further, aforesaid flue type waste heat boiler water-cooled quick opening manhole device, described lower shell side is provided with lower shell water inlet and lower shell delivery port.
The invention has the beneficial effects as follows: the present invention is arranged to the Internal and external cycle sandwich type structure by manhole lower shell, manhole upper cover plate, and water flowing is cooling, simultaneously the bolt of original flange connect is made into to the form that wedge inserts pull bar, effectively extended manhole device's service life, avoided burning because of manhole the generation of the excessive phenomenon of tobacco dust caused, the work that has also greatly alleviated manhole device's maintenance is artificial.The design's fabricated structure, assembling and convenient disassembly, applicability is strong.
