Description

Technical Field

[0001] The utility model relates to the technical field of pouring equipment, and particularly relates to a fixed-point pouring centralized dust removal device. Background Art

[0002] During the steelmaking process, most raw steel materials are heated to prepare molten iron, and then the molten iron is subjected to operations such as dephosphorization, desulfurization, and slag skimming. Then, the molten iron is poured into a mold for cooling, and finally the required iron products are obtained.

[0003] During the transportation of molten iron, an iron ladle is mostly used for transportation. The molten iron is stored in the iron ladle. When pouring the molten iron, the iron ladle is placed on a tilting machine, and then the tilting machine is used to tilt the iron ladle so that the molten iron in the iron ladle flows out.

[0004] During actual operation, when the molten iron is poured out of the iron ladle, it is easy to generate a large amount of smoke. The dispersion of the smoke in the production workshop is likely to affect the physical health of the operators. Moreover, during the process of pouring molten iron from the iron ladle, the degree of automation is low and it depends on manual operation, which makes the work intensity of the operators large and has a certain degree of danger.

[0030] In addition, a camera is provided on one side of the first track 10. The casting images of each of the ingot mold cars 1 are observed through the camera to determine whether the casting is completed.

[0031] It should be noted that at least one limiting groove is provided on the transport vehicle 2, and a clamping block a1 that can cooperate with the limiting groove is provided on the side wall of the lower end of the ladle A.
