Description

Heat-stewing cover with lifting lugs

The technical field is as follows:

the utility model belongs to the technical field of metallurgical slag heat braising treatment, a steel slag heat braising treatment process units is related to, especially relate to a heat braising cover with lug for metallurgical slag heat braising treatment occasion.

Background art:

the steel slag is a byproduct discharged in steel-making production by steel enterprises. The effective recovery of scrap steel and the high-value utilization of steel slag from steel slag are important issues facing steel enterprises. The steel slag treatment process becomes an important link of steel-making engineering design. At present, the steel slag once treatment process which is widely applied at home and abroad mainly comprises a hot splashing method, a water quenching method, an air quenching method, a hot stewing method, a roller method and the like. The hot stewing method is the mainstream steel slag treatment process at present and is popularized and applied in most domestic steel mills, the process is that molten steel slag generated by steel making is directly tipped into a hot stewing pit through a crane, and after the steel slag is poured into the hot stewing pit every time, a large block of slag is turned and smashed through an excavator, and water is manually pumped for cooling; when the loading amount reaches about 80% of the volume of the hot stewing slag pit, the hot stewing cover is buckled above the hot stewing pit through a crane, the steel slag is digested by automatically controlling water spraying to generate steam, after 8-12 hours, when the temperature in the hot stewing pit is reduced to be below 60 ℃, the hot stewing cover is lifted away through a travelling crane, the steel slag is shoveled out by an excavator for next treatment, when the hot stewing cover is lifted up conventionally, an on-ground worker is required to cooperate with a crane driver in a workshop to carry out lifting, the crane is opened above the hot stewing cover, a secondary hook of the crane falls down, an operation work station is operated above the hot stewing cover, 4 steel wire ropes or chains which are matched with the secondary hook of the crane are respectively hung in hooks around the hot stewing cover, and the hot stewing cover is lifted after the worker falls down from the hot stewing cover. Because the hot braising cover is arranged above the hot stuffy pit, the surface temperature of the hot braising cover is very high, and steam escapes from time to time, so that certain danger exists in the operation of workers on the hot braising cover. Therefore, there is a need to solve these problems by developing a heat-sealed lid that eliminates the need for a manually assisted hook.

The invention content is as follows:

the utility model discloses an invention aims at overcoming the shortcoming that prior art exists, designs to provide a heat braised lid with lug, and the crane driver alone can carry out the hanging of heat braised lid and put, need not carry out supplementary couple with the help of the ground manual work.

In order to realize the purpose, the heat stewing cover main body structure with the lifting lugs of the utility model comprises a heat stewing cover body, lifting lugs, a spray header and a nozzle; the hot-braising cover body is a rectangular frame formed by welding steel plates, and longitudinal and transverse reinforcing ribs are arranged in the hot-braising cover body so as to ensure the integral rigidity of the hot-braising cover body; two sets of lifting lugs in a tripod form are installed at the top of the hot braising cover body, the distance between the centers of the two lifting lugs is the same as that between the centers of the two crane plate hooks outside, each group of lifting lugs comprises an upper pin shaft, two lower pin shafts, two lifting arms and a plurality of reinforcing rib plates, the upper ends of the two lifting arms are connected through the upper pin shaft, the lower ends of the two lifting arms are installed at the top of the hot braising cover body through the lower pin shafts respectively, the distance between the two lifting arms is set according to the advancing and retreating space of the crane plate hooks outside, the reinforcing rib plates are arranged at the lower parts of the two lifting arms, the number of the reinforcing rib plates is determined according to the length of the lifting arms, a spray pipe is fixed at the middle position inside the hot braising cover body, nozzles are uniformly distributed.

Compared with the prior art, the utility model, have following advantage: firstly, the hot-covered cover can be lifted by one person through a crane driver without the help of ground manual work, the operation time of lifting the hot-covered cover by the crane is shortened, the operation efficiency in a workshop is improved, and the labor intensity of workers is reduced; and secondly, the probability of contact between workers and a high-temperature environment is reduced, and conditions are created for safe production.
