Technical Field
[0001] The utility model belongs to the technical field of deep well casting, and in particular relates to a cofferdam isolation structure for preventing aluminum liquid from meeting water. Background Art
[0002] There is slag accumulation in the furnace eye of the casting furnace. During the casting process, the high temperature melts the accumulated slag and it suddenly falls off, causing an abnormal increase in the flow rate of molten aluminum. In the absence of a cofferdam to prevent aluminum leakage, if aluminum overflow from the flow channel is not handled in time, the molten aluminum may flow into the casting well and explode, or overflow onto the ground and cause high-temperature fires in nearby equipment and other uncertain accidents. Utility Model Content

Through the arrangement of the functional parts, impurities that may exist at the various corners inside the cofferdam structure can be easily extracted and cleaned, and the operation is very convenient.
[0005] Preferably, a wall groove is provided at each corner of the inner side surface of the cofferdam structure, and a placement groove connected to the wall groove is provided on the top surface of the mounting surface. The functional parts are placed in the wall groove and the placement groove, so as to separate impurities adhered to the corners of the inner wall of the cofferdam structure and facilitate subsequent cleaning.
[0006] Preferably, the functional component is a functional plate, and the inner side surface of the functional plate is in the same plane as the inner wall of the cofferdam structure and the top end surface of the mounting surface.
[0007] Preferably, an annular groove is provided on the top surface of the cofferdam structure, and the annular groove is not connected to the wall groove. During use, lightweight insulation materials or other fillers can be placed in the annular groove as needed to reduce heat conduction and avoid damage caused by accidental contact with the outer wall of the cofferdam structure.
[0008] Preferably, the outer surface of the cofferdam structure is also provided with a rear groove, in which a through hole connected to the annular groove is provided. In actual use, cooling pipes and the like can be first arranged in the annular groove, and then pass through the through hole and connected to external equipment, thereby improving the functionality of the cofferdam structure.
[0009] Preferably, a casting furnace is placed in the inner area of the cofferdam structure; there is slag accumulation in the furnace eye of the casting furnace. During the casting process, the high temperature melts the accumulated slag and it suddenly falls off, causing an abnormal increase in the flow rate of molten aluminum. At this time, the molten aluminum is blocked by the cofferdam structure to prevent the molten aluminum from flowing into the casting well and causing an explosion or overflowing onto the ground, causing high-temperature fires in nearby equipment and other uncertain accidents; the cofferdam structure is cast vertically to the installation surface.
[0010] Preferably, at least one independent area is formed between the cofferdam structure and the mounting surface.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
