Description
Technical field
This utility model relates to a kind of gas piping connecting device, particularly a kind of vertical ladle baking facility.
Background technology
Development along with smelting technique, the effect that ladle, centre (tank) wrap there occurs very big change, it not the container only transporting molten steel, but become an important component part of molten steel refining technology, the demand of high-quality steel and the development of higher temperature smelting technique, requirement has ladle baking facilities novel, efficient and high performance ladle liner for its service, development and utilization along with refractory technology, largely also reduce the heat loss of casting process molten steel, extend the service life of liner to a certain extent. In order to improve the temperature levels of ladle, centre (tank) ladle-lining equably, to reduce the heat loss of pouring molten steel process and to extend the service life of liner, simple dependence refractory material is not enough far away, ladle, centre (tank) have to be wrapped the baking that is dried in advance and heats up, in this context, apparatus for baking development and differentiation. After experienced by simple gas toast stage, air-breathing baking stage, now with the appearance of high-temp combustion technology, heat accumulating type baking technology is just approved by numerous producers. In the use procedure of apparatus for baking, vertical baking is one comparatively conventional in current smelting system. Vertical apparatus for baking is mainly installed on the support near bag mouth, needs to remove when ladle, the lifting transhipment of centre (tank) bag, adopting more and be flipped up formula baking current vertical baking. Owing to roaster combustion medium is coal gas (coke-stove gas, blast furnace gas, coal gas of converter etc.), the gas occurred when coal gas is by carbonaceous material imperfect combustion, main component is carbon monoxide, no color or smell, poisonous, after being sucked by humans and animals, the hemoglobin in blood is combined (stronger than the binding ability of oxygen Yu hemoglobin, cause a degree of anoxia) can cause poisoning, Given this characteristic be flipped up the key of formula baking when being exactly overturn the connection of gas piping must not leak.Conventional gas piping type of attachment is soft connection: rubber hose connects, flange-connection stainless steel metal flexible pipe connects, although both types of attachment solve the problem of bending, but life-span and sealing property are limited, and potential safety hazard is bigger.
Summary of the invention
The technical problems to be solved in the utility model is for the deficiencies in the prior art, it is proposed to one is not easily revealed, and can improve the vertical ladle baking facility in short sword service life.
The technical problems to be solved in the utility model is achieved through the following technical solutions, a kind of vertical ladle baking facility, arm is accessed including coal gas, column assembly and the ladle being arranged on column assembly side, it is provided with clad at the upper opening place of ladle, clad is connected with column assembly by clad lifting device, it is characterized in: described clad lifting device includes slip up wheels, downslide wheels and by the hinged driving arm in horizontally hinged axle and column assembly top, arm and horizontally hinged axle is driven to be fixedly connected, it is provided with turning arm between the horizontally hinged axle in the left and right sides and the clad that drive arm, one end of turning arm and horizontally hinged axle are fixedly connected, the other end of turning arm connects with clad, the center of described clad is provided with heat storage tank, heat storage tank is provided with burner, burner is provided with burner interface pipe, burner interface pipe and coal gas access and are provided with, between arm, the gas piping swivel joint being easy to turn on clad, described slip up wheels are mounted remotely from driving arm one end of horizontally hinged axle, described downslide wheels are arranged on the bottom of column assembly, between upper and lower assembly pulley, it is provided with Wound steel rope drives the hoist engine driving arm to rotate.
The technical problems to be solved in the utility model can also be come to realize further by the following technical programs, described gas piping swivel joint includes inner ring and the outer ring being sleeved on inner ring, it is fixedly connected with lower flange in the lower section of inner ring, lower flange and burner interface pipe are fixedly connected, at the upper flange that is arranged over of inner ring, upper flange accesses arm be fixedly connected with outer ring, coal gas respectively; It is provided with steel ball rolling channel between outer wall and the inwall of outer ring of described inner ring, some rollers realizing the independent rotation of inside and outside circle are installed in steel ball rolling channel.
The technical problems to be solved in the utility model can also be come to realize further by the following technical programs, is provided with main sealing device between inner ring and lower flange.
Compared with prior art, this utility model utilizes and is arranged on burner interface pipe and coal gas and accesses the gas piping swivel joint being easy to turn on clad between arm, effectively solves the radiation of conventional coupling arrangement non-refractory, security hidden trouble that material aging, Long-term bend damage bring. This utility model simple in construction, manufacturing cost is moderate, and service life is also longer, safeguards simple, according to using periodic replacement main sealing device and can to add appropriate butter at raceway, safety has but had large increase than rubber hose, flange-connection stainless steel metal flexible pipe.
