Description
Technical Field
The utility model belongs to the technical field of the casting equipment, concretely relates to prevent molten iron casting ladle that splashes.
Background
The ladle is a tool for casting operation in a foundry, the molten iron that finishes smelting in the smelting furnace is transported to casting sand mould department through the ladle and is cast the operation, traditional molten iron ladle, its structure includes the casting ladle, empty the driving piece and carry and draw the structure, for making things convenient for the casting ladle to connect the molten iron, the top of casting ladle is uncovered setting, and set up like this, the molten iron surface contacts with the air, in-process of the casting ladle is transported in the driving, the molten iron surface forms the dross fast, and the molten iron problem of leaking outward that splashes can also appear, in addition because the driving piece of empting at present is manual start usually, in the casting process, also can have the problem that the molten iron splashes, above-mentioned these problems not only make the molten iron quality descend, still make very big potential safety hazard to the staff.
To above-mentioned problem, there is the technique to improve the casting ladle at present, and a top cap is articulated at the top of casting ladle promptly, when connecing the molten iron and casting, the staff opens the top cap earlier, casts again, and such mode has reduced the problem that the molten iron splashes in the transportation to a certain extent, nevertheless because the top cap needs the manual work to open, has increased staff's the operation degree of difficulty again.
SUMMERY OF THE UTILITY MODEL
Not enough to exist among the prior art, the utility model provides a prevent molten iron casting ladle that splashes to the top cap of addding can increase the problem of the staff operation degree of difficulty among the solution prior art.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
an anti-splashing molten iron casting ladle comprises a casting barrel, a pouring driving piece and a lifting structure, wherein a casting nozzle close to the top is arranged on the casting barrel, the top of the casting barrel is provided with an end cover which comprises a first arc-shaped plate and a second arc-shaped plate, the diameter of the first arc-shaped plate is larger than the outer diameter of the casting barrel, and is arranged close to the casting nozzle, the first arc-shaped plate is coaxially arranged with the casting barrel, the diameter of the second arc-shaped plate is smaller than the inner diameter of the casting barrel, a connecting seat is fixed at the bottom of the end cover, the connecting seat is arranged deviating from the central axis of the first arc-shaped plate, and the connecting seat is arranged at one side far away from the pouring nozzle, the bottom of the second arc-shaped plate is provided with a balancing weight, a rotating rod horizontally arranged is fixed on the connecting seat, the rotating rod is rotatably connected to the inner wall of the casting barrel, a pouring nozzle is perpendicular to the rotating rod along a straight line formed by the casting barrel, and when the central axis of the casting barrel is in a vertical state, the end cover is parallel to the horizontal plane.
Compared with the prior art, the utility model discloses following beneficial effect has:
this scheme is when the casting, the casting ladle slope, and the pouring nozzle is close to the sprue gate of sand mould, and this in-process is because the connecting seat of end cover bottom is eccentric settings, and the end cover rotates through the bull stick and connects on the casting ladle, so the end cover is for keeping the horizontality, and its first arc that is close to pouring nozzle one side and the increase of distance between the pouring nozzle, and the second arc gets into in the casting ladle to make the molten iron can follow the pouring nozzle and flow out, the molten iron receives the end cover again to block unable splash casting ladle simultaneously.
Therefore, the molten iron casting ladle adopting the scheme has the advantages that in the casting ladle moving process, the molten iron is shielded by the end cover to reduce the contact with air, the quality of the molten iron is improved, in addition, the end cover automatically leaves the casting nozzle without manual opening during pouring, and the safety production of workers is ensured.
Furthermore, a limiting groove is formed in the bottom surface of the first arc-shaped plate, and when the central axis of the casting barrel is in a vertical state, the top edge of the casting barrel is located in the limiting groove. The arrangement improves the sealing performance of the end cover on the casting barrel.
Further, the top surface of the pouring nozzle is lower than the top surface of the casting ladle. After the casting is finished, even molten iron remained on the pouring nozzle cannot contact with the end cover, and the problem that the end cover is solidified on the casting barrel is solved.
Furthermore, a baffle plate positioned below the rotating rod is fixed in the casting barrel, and an upwards inclined guide plate is fixed on one side of the baffle plate close to the pouring nozzle. The arrangement can avoid the influence of molten iron on the rotation of the rotating rod.
Furthermore, be fixed with the honeycomb duct that is located the casting ladle inside on the casting ladle lateral wall, the honeycomb duct is the shape of falling L, and the upper end of honeycomb duct is located the top of baffle, and link up the lateral wall of casting ladle, and the lower extreme of honeycomb duct link up the baffle. Therefore, molten iron can be poured into the casting barrel through the guide pipe without opening the end cover at the top.
Furthermore, an openable cover plate for sealing the guide pipe is arranged on the outer wall of the casting barrel. Therefore, in the moving process of the casting ladle after the molten iron is connected, the external oxygen is reduced from entering the guide pipe.
Furthermore, the middle-upper portion symmetry of casting ladle outer wall is fixed with the mount pad, all is fixed with the back shaft that the level set up on the mount pad, carries to draw the structure and includes the crossbearer, and the crossbearer both ends are fixed with the connecting rod respectively, and the connecting rod perpendicular to crossbearer sets up, and the connecting rod bottom is fixed with the bearing frame, installs ball bearing in the bearing frame, and the back shaft passes through ball bearing and is connected with the bearing frame rotation, and the crossbearer middle part is fixed with rings. Therefore, the casting ladle can move back and forth through the matching of the lifting hook and the lifting ring on the travelling crane.
Furthermore, the dumping driving piece comprises a motor and a speed reducer, and an output shaft of the speed reducer is fixedly connected with one of the support shafts. The torque of the motor is transmitted to the supporting shaft through the speed reducer, so that the casting ladle can be slowly inclined, and molten iron slowly enters the cavity of the sand mold.
