Description

Technical Field

[0001] The utility model relates to the technical field of charging of smelting furnaces, and particularly relates to a charging device for a smelting furnace. Background Technique

[0002] A smelting furnace refers to a device that melts metal ingots and some waste metals and adds necessary alloy components, and melts them into the required alloy through operations such as slag skimming and refining. To ensure the quality of the ingots of metal alloys and extend the service life of the smelting furnace as much as possible, various preparatory work of the smelting furnace must be done well in the actual production process, including charging, furnace drying, furnace washing, furnace cleaning, stirring, slag skimming and refining operations. When the smelting furnace is working normally, especially involves a charging operation process. Generally, the existing small factory smelting furnace manually pours materials from a hopper into the interior of the smelting furnace.

[0003] For example, a charging device for an external smelting furnace provided in a Chinese patent application with the publication number of CN216080955U. Through the setting of a telescopic damping rod, a pushing plate and a receiving box, and the mutual cooperation of the three, the metal waste located inside the receiving box is automatically pushed out under the action of the telescopic damping rod and the pushing plate, and falls into the interior of the smelting furnace tank through the through hole at the bottom of the receiving box, thereby completing the semi-automatic charging work, avoiding the operator getting too close to the surface of the smelting furnace tank when charging, and when being overly fatigued, it is easy to cause scalding accidents, and further ensuring its safety and stability during work.

[0004] However, there are still the following problems in this technical solution: the charging port of the receiving box in this technical solution is relatively high, and people need to raise their arms to pour the waste into the receiving box, which consumes a lot of manpower and time and is difficult to charge. Summary of the Utility Model

[0005] Therefore, the embodiment of the utility model provides a charging device for a smelting furnace to solve the problem that it is laborious and time-consuming for people to raise their arms to pour waste into the receiving box due to the relatively high charging port of the receiving box in the prior art.
