Description

Technical Field

[0001] This utility model relates to the field of conveying device technology, specifically a conveying device for molten aluminum in a smelting furnace. Background Technology

[0002] In aluminum alloy smelting production, after the molten aluminum is added to the smelting furnace to meet the qualified standards, it is transported to the casting machine through a chute for casting. However, during this transportation process, the molten aluminum exchanges heat with the external environment, causing the temperature to drop continuously. The decrease in the temperature of the molten aluminum will have many adverse effects on the quality of the aluminum rod, such as causing uneven internal structure, producing defects such as porosity and shrinkage, reducing the mechanical properties and surface quality of the aluminum rod, and seriously affecting the product qualification rate and production efficiency. At present, most existing chutes do not have effective heat preservation measures and cannot meet the strict requirements of aluminum temperature for high-quality aluminum alloy casting. Utility Model Content

[0003] The main objective of this invention is to provide a molten aluminum conveying device for a smelting furnace, thereby solving the problem that the molten aluminum conveying device in the aluminum alloy smelting production process lacks effective heat preservation measures and cannot meet the strict temperature requirements of molten aluminum for high-quality aluminum alloy casting.

[0004] To achieve the above objectives, this utility model provides an aluminum molten metal conveying device for a smelting furnace, including a chute, with a chute cover at the top. The chute cover includes a stainless steel plate at the top, a ceramic fiber felt plate in the middle, and an aluminum plate at the bottom.

[0005] Furthermore, the ceramic fiber felt plate is provided with an installation groove that opens to the bottom, and a heating rod is installed in the installation groove.

[0006] Furthermore, a temperature sensor is fixedly connected to the bottom of the tank cover.

[0007] Furthermore, one side of the trough cover is hinged to the chute, and the other side is connected to the chute via a pressure plate assembly.

[0008] Furthermore, the pressure plate assembly includes a screw fixedly connected to the chute, a pressure plate movably connected to the screw, and a nut threadedly connected to the screw and located above the pressure plate.

[0009] The groove cover of this utility model has a multi-layer composite structure. The stainless steel plate at the top protects the internal insulation structure from external environmental corrosion and mechanical damage; the ceramic fiber felt plate in the middle has a heat preservation effect, which greatly reduces heat loss; and the aluminum plate at the bottom can quickly conduct heat and reduce heat accumulation in local areas.

[0010] This invention, by incorporating a heating rod, can replenish the heating of molten aluminum when significant temperature loss occurs. Furthermore, by using a temperature sensor, the temperature of the molten aluminum can be detected, ensuring that the molten aluminum remains within a suitable temperature range throughout the transportation process.

[0011] This invention, by setting up a pressure plate assembly, can ensure that the pressure plate and the chute are tightly pressed together, thus guaranteeing a sealing effect. Attached Figure Description

[0016] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] like Figures 1 to 2 As shown in the embodiment of this utility model, a molten aluminum conveying device for a smelting furnace is provided for conveying molten aluminum from a smelting furnace to a casting machine. The molten aluminum conveying device includes a chute 1, and a chute cover 2 is provided on the top of the chute 1. The chute cover 2 includes a stainless steel plate 201 at the top, a ceramic fiber felt plate 202 in the middle, and an aluminum plate 203 at the bottom. The chute cover 2 has a multi-layer composite structure. The stainless steel plate 201 at the top protects the internal insulation structure from external environmental corrosion and mechanical damage. The ceramic fiber felt plate 202 in the middle has a heat preservation function, which greatly reduces heat loss, reduces quality defects of aluminum bars caused by temperature problems, and improves the quality of aluminum bars and the product qualification rate. The aluminum plate 203 at the bottom can quickly conduct heat and reduce heat accumulation in local areas.

[0018] The ceramic fiber felt board 202 is provided with an installation groove 202a that opens to the bottom, and a heating rod 204 is installed in the installation groove 202a; a temperature sensor 4 is fixedly connected to the bottom of the groove cover 2; the temperature sensor 4 is electrically connected to the control system of the heating rod 204.

[0019] The heating rod 204 can supplement the heating of the molten aluminum when the temperature loss is severe. The heat generated by the heating rod 204 is quickly conducted to the air in the chute through the aluminum plate 203, and then to the molten aluminum in the chute. By setting the temperature sensor 4, the temperature of the molten aluminum can be detected and the heating rod 204 can be started or stopped to ensure that the molten aluminum is always kept within a suitable temperature range during the transportation process.

[0020] In some embodiments, one side of the trough cover 2 is hinged to the chute 1 via a hinge, and the other side is connected to the chute 1 via a pressure plate assembly 3. The pressure plate assembly 3 includes a screw 301 fixedly connected to the chute 1, a pressure plate 302 movably connected to the screw 301, and a nut 303 threadedly connected to the screw 301 and located above the pressure plate 302. By setting the pressure plate assembly 3, it is possible to ensure that the pressure plate 302 and the chute 1 are tightly pressed together, thus ensuring a sealing effect.

[0021] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
