Abstract
The utility model relates to a sealing device of a drying roller of a pickling tank, comprising the pickling tank, the drying roller and the sealing device, wherein a cover is arranged on the pickling tank, and the sealing device is arranged at the connecting position of two ends of the drying roller and a pickling tank body. The sealing device of the drying roller of the pickling tank is characterized in that the sealing device also comprises a fixing plate and a sealing plate, wherein the fixing plate is fixed on the pickling tank body, the sealing plate is provided with a rack which is engaged with a gear wheel which is arranged on the fixing plate and can move along the rotation of the gear wheel, and the sealing plate is fixed between the fixing plate and a cover plate by the cover plate. The sealing plate can be opened through the moving of the rack on the sealing plate along the gear wheel arranged on the fixing plate, thereby realizing the replacement of the drying roller, the roller replacement time is greatly saved, the working efficiency is increased, the corrosion to the equipment and the pollution to the environment of the acid liquor and the acid mist which is volatilized from the acid liquor are avoided, therefore, the environmental protection effect is good.
Description
Technical field
The utility model belongs to hot-strip pickling technical field, particularly a kind of sealing device of descaling bath squeeze roll.
Background technology
The band steel because will be at a certain temperature and the water and air interface, therefore, can form oxide at belt steel surface, and further need to remove these oxides before the processing after rolling or rolling.The method of removing the belt steel surface oxide mainly contains methods such as machinery and chemical pickling, and the chemical pickling method promptly adopts acid solution to clean and removes iron rust and foreign material, and it is most widely used.The strip pickling device is made of several sections descaling baths, because the function difference of every section descaling bath, corresponding acid strength is also different with temperature, therefore, needs to stop the acid solution between the descaling bath to mix in the course of the work.In order to stop the acid solution between the different section descaling baths to be mixed, be provided with squeeze roll between per two sections descaling baths, also be provided with squeeze roll at first descaling bath inlet and the outlet of last descaling bath simultaneously, to prevent being with steel to take acid solution out of descaling bath.Because the squeeze roll roll surface is lined with acid-resisting rubber, through after working long hours, acid-resisting rubber can wear and tear, and extracts effect thereby reduce, and therefore, after using for 1～2 week, needs to change a squeeze roll.The interface of the cell body of squeeze roll and descaling bath is provided with sealing device, leaks to prevent that acid solution spills with acid mist in acid cleaning process.
Existing descaling bath squeeze roll sealing device is fixed on the descaling bath, when needs are changed squeeze roll, at first to emit the acid solution in the descaling bath, treat to clean descaling bath again after the acid solution emptying, open descaling bath groove lid then and, just can carry out the roll change action, after finishing roll change the sealing device taking-up, again sealing device is reinstalled on the descaling bath, and close the locked groove lid.Since squeeze roll quantity more (syllogic turbulent flow descaling bath has 10 squeeze rolls), and in the roll change process, back work has occupied most of the time, therefore, has had a strong impact on production efficiency; And the acid solution owing to needing to emit before each roll change in the descaling bath has also increased production cost greatly; Simultaneously, though acid solution emptying and cleaning, still can the residual fraction acid solution, when opening the groove lid, the acid mist that residual acid solution and volatilization thereof form will pollute and corrodes environment and equipment.
The utility model content
It is to realize like this that the purpose of this utility model is to provide a kind of descaling bath squeeze roll sealing device the purpose of this utility model of being convenient to change squeeze roll, a kind of descaling bath squeeze roll sealing device, comprise descaling bath, squeeze roll and sealing device, be provided with the groove lid above the described descaling bath, described sealing device is arranged on the position of described squeeze roll two ends and descaling bath cell body interface, it is characterized in that: described sealing device comprises fixed head and sealing plate, described fixed head is fixed on the described descaling bath cell body, described sealing plate is provided with tooth bar, described tooth bar be arranged on the gears engaged on the described fixed head and can move with the rotation of described gear, described sealing plate is fixed between described fixed head and the cover plate by cover plate.
For guarantee sealing plate move fast, reliable, above-mentioned tooth bar is arranged on the upper edge and the lower edge of above-mentioned sealing plate.
For easy to operate, said gear drives above-mentioned sealing plate by the rotation of gear drive handle and moves.
In order to prevent that by acid liquid corrosion said fixing plate, sealing plate, gear and cover plate are polypropylene material or acid resisting material.
Above-mentioned squeeze roll comprises squeeze roll and following squeeze roll, and described two ends of going up squeeze roll are provided with the squeeze roll lowering or hoisting gear, and the described two ends of squeeze roll down are provided with down the squeeze roll lowering or hoisting gear.
One side of above-mentioned descaling bath is provided with changing rig.
The utlity model has following beneficial effect, the utility model is by being provided with tooth bar and moving along the gear that is arranged on the fixed head on the sealing plate, can open or close sealing plate, realize the replacing of squeeze roll, not only saved roll changing time significantly, improved operating efficiency, and avoided corrosion and the pollution on the environment of the acid mist of acid solution and volatilization thereof, had good environment protecting equipment.
