Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of industrial furnace of metal smelting, especially to an industrial furnace with a preheating chamber. BACKGROUND

[0002] The industrial furnace is a new type of high-efficiency furnace developed according to the metal smelting process. The current industrial furnace usually comprises a melting chamber and a temperature rising chamber in communication. When the metal is melted, the metal material is put into the melting chamber, and the molten metal is heated in the temperature rising chamber, and then flows into the melting chamber through the through hole to melt the metal material. The molten metal after melting flows back to the temperature rising chamber for heating. The molten metal circulates and exchanges between the melting chamber and the temperature rising chamber, so that the metal smelting can be realized efficiently and quickly.

[0003] However, when the metal material is put into the melting chamber, if the metal material is attached with oil and moisture, when the moisture contacts the aluminum liquid, because the temperature difference is too large, the moisture evaporates instantaneously, and the volume expands rapidly, thereby causing the explosion in the furnace, and there is a great safety risk.

[0016] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0017] like Figure 1 , 2 As shown, an industrial furnace with a preheating chamber includes a melting chamber 1, a heating chamber 2, and a preheating chamber 3. The melting chamber 1 has a molten metal chamber 11 for storing high-temperature molten metal. The melting chamber 1 and the heating chamber 2 are connected, and both are equipped with openable furnace doors 12 and 21. The melting chamber 1 is equipped with a spare burner 4, and the heating chamber 2 is equipped with a regenerative burner 5. A partition wall 6 is provided between the melting chamber 1 and the heating chamber 2, and the partition wall 6 has a through hole 61 connecting the molten metal chamber 11 and the heating chamber 2. Through this structure, the high-temperature molten metal circulates and exchanges fluidly. The molten metal flows into the molten metal chamber 11 of the melting chamber 1 to melt the metal material, and then flows into the heating chamber 2 for heating.

[0018] The preheating chamber 3 is connected to the melting chamber 1. This connection allows residual heat from the melting chamber 1 to be transferred to the preheating chamber 3. The preheating chamber 3 is used to preheat the metal material. It is equipped with an openable furnace door 31. Before entering the melting chamber 1, the metal material is placed in the preheating chamber 3. In the preheating chamber 3, the residual heat from the melting chamber 1 evaporates moisture from the surface of the metal material and burns off any oil, thus preventing an internal explosion when the subsequent metal material is placed into the melting chamber 1 and effectively reducing safety risks. While the metal material is preheating in the preheating chamber 3, another batch of metal material is placed into the molten chamber 11 of the melting chamber 1 for melting. The preheating and melting times do not conflict, and the preheated metal material, at a higher temperature, reduces the time required for heating and melting when placed into the molten chamber 11, thereby improving melting efficiency to some extent.

[0019] The preheating chamber 3 is positioned higher than the molten metal chamber 11, and the bottom surface of the preheating chamber 3 is configured as a sloping surface 32 that slopes downward toward the molten metal chamber 11. This structure facilitates the pushing of preheated metal material in the preheating chamber 3 into the molten metal chamber 11 along the sloping surface 32 for melting, preventing the metal material from getting stuck in the preheating chamber 3.

[0020] The above-described embodiments are merely illustrative of this utility model. Any equivalent embodiments made by those skilled in the art without departing from the technical features disclosed in this utility model, and without departing from the technical features of this utility model, shall still fall within the scope of the technical features of this utility model.
