Aluminum alloy, as a leader among non-ferrous metal structural materials, is widely used in various industries. Its market demand continues to rise, driving the vigorous development of aluminum alloy smelting technology. In this context, aluminum alloy melting furnaces have become key equipment, shouldering the important task of converting raw materials into high-quality alloys. In order to meet the needs of efficient and continuous production, the supporting feeding device of aluminum alloy melting furnaces is particularly important. The existing melting furnace feeding device has certain disadvantages when used.

The advantages of the utility model are: a feeding structure that can be rotatably adjusted is provided directly above the melting furnace, and the angle of the feeding structure is adjusted according to the feeding demand, so that the feeding structure can block the material and reduce the material feeding, and can also introduce the material into the interior of the melting furnace. The angle of the feeding structure can change the state of the material outlet, which is convenient for intermittent feeding into the interior of the melting furnace during the processing, which is beneficial to the continuous processing of the melting furnace."

When feeding materials into the melting furnace, workers need to approach the melting furnace and manually open the sealing cover. This will directly expose them to the high temperature environment, increasing the risk of safety accidents such as scalding and burns. Therefore, a safety protection device for power detection is needed to solve the above problems. Utility Model Content
