[0002] Aluminum products are made of aluminum and other alloy elements. They are usually first processed into castings, forgings, foils, plates, strips, tubes, rods, profiles, etc., and then made through processes such as cold bending, sawing, drilling, assembly, and coloring. The main metal element is aluminum, and some alloy elements are added to improve the performance of aluminum. Aluminum is one of the most important non-ferrous metal varieties. It is widely used because of its good properties of low density, plasticity and formability.

[0003] At present, during the aluminum smelting process, there is often a large amount of waste slag floating on the surface of the molten liquid. In order to ensure the smelting quality, the surface waste slag needs to be spread flat on the surface of the aluminum liquid to maintain the smelting temperature and melt the aluminum completely. When the smelting is completed and ready to be dumped, all the floating waste slag needs to be salvaged to ensure the purity of the aluminum liquid. Most of these tasks are currently done manually, which has low work efficiency and certain risks. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] In the embodiment, Figure 1-3 A melting furnace is provided, comprising a furnace body 1, a furnace cover 2 is arranged on the top of the furnace body 1, a stirring device 3 is arranged on the top of the furnace cover 2, three slider mechanisms 4 are arranged in a circular array at the bottom of the furnace cover 2, chains 5 are arranged at the bottom of the three slider mechanisms 4, the bottoms of the three chains 5 are connected to a slag scooping net 6, and a limiting device 7 for spreading the slag scooping net 6 is arranged inside the furnace body 1.

[0024] Reference Figure 1-3 , wherein the stirring device 3 includes a driving motor 31, the driving motor 31 is fixedly installed on the top of the furnace cover 2, the output end of the driving motor 31 penetrates and extends to the bottom of the furnace cover 2 and is connected to a rotating rod 32, and the bottom end of the rotating rod 32 is fixedly connected to a flat plate 33;

[0025] Through the above-mentioned structural setting, the driving motor 31 is started, and the driving motor 31 drives the leveling plate 33 to rotate through the rotating rod 32, so that the waste slag on the surface of the aluminum liquid is evenly leveled during the smelting process, serving as a heat protection layer when the aluminum liquid is heated to prevent saturation and oxidation by furnace gas.

[0026] Reference Figure 2-3 , wherein the slider mechanism 4 includes a sliding groove 41, the bottom of the furnace cover 2 is fixedly installed with the sliding groove 41, the inside of the sliding groove 41 is slidably installed with a sliding block 42, and the bottom of the sliding block 42 is fixedly connected with a chain 5;

[0027] Through the above-mentioned structural arrangement, when the furnace cover 2 is lifted, the slider mechanism 4 drives the slag scooping net 6 at the bottom of the furnace body 1 to rise together through the chain 5. The slag scooping net 6 scoops the waste slag in the aluminum liquid to the surface during the rising process. With the weight of the waste slag, the slag scooping net 6 drives the sliding block 42 to shrink in the sliding groove 41 through the chain 5, so that the slag scooping net 6 is gathered inward into a bag shape, and at the same time, the positioning pin 8 is pulled out from the positioning slot 73 to release the fixing of the slag scooping net 6 by the annular frame 72.

[0028] Reference Figure 2-3 The limiting device 7 includes a limiting groove 71, the furnace body 1 has a limiting groove 71, a ring frame 72 is slidably installed inside the limiting groove 71, the top of the ring frame 72 is inclined, and a plurality of positioning slots 73 are opened thereon;

[0029] Through the above-mentioned structural setting, by setting the limiting groove 71, after the positioning pin 8 is inserted into the positioning slot 73, the slag scooping net 6 is flattened. As the annular frame 72 slides inside the limiting groove 71 to the bottom of the furnace body 1, the annular frame 72 set on the inclined surface can collect all the floating waste slag into the slag scooping net 6.

[0030] Reference Figure 2-3 , wherein the connection between the chain 5 and the slag scoop net 6 is fixedly installed with a positioning pin 8 adapted to the positioning slot 73;

[0031] Through the above-mentioned structural arrangement, after the positioning pins 8 are respectively inserted into the positioning slots 73, the slag scooping net 6 can be fully opened and spread flat to the bottom of the furnace body 1, effectively increasing the salvage area of ​​the slag scooping net 6, and being able to salvage the waste slag inside the furnace body to the maximum extent. The horizontal insertion can facilitate quick plugging and unplugging, and can also use gravity to prevent the positioning pins 8 from falling off when the annular frame 72 moves up and down.

[0032] Reference Figure 1-2 , wherein the inner bottom end of the furnace body 1 is set in a conical shape, and a plurality of lifting rings 9 are fixedly installed on the top of the furnace cover 2, and the plurality of lifting rings are distributed in a circular array;

[0033] Through the above-mentioned structural arrangement, the lifting ring 9 on the top of the furnace cover 2 is convenient for others to use equipment to lift the furnace cover 2 for work, and the conical arrangement at the bottom of the furnace body 1 is convenient for the slag scooping net 6 to be laid flat on it when it falls.

[0034] Working principle:

[0035] The first step to implement the innovation point:

[0036] Step 1: Put the aluminum to be smelted into the furnace body 1, cover the furnace cover 2 and start smelting. During the smelting process, add a refining agent into the furnace body 1 to make the impurities in the aluminum liquid form waste slag floating on the surface. After the waste slag is formed, start the drive motor 31. The drive motor 31 drives the flattening plate 33 to rotate through the rotating rod 32. During the smelting process, the waste slag on the surface of the aluminum liquid is evenly flattened as a heat protection layer when the aluminum liquid is heated to prevent saturation and oxidation by furnace gas.

[0037] Step 2: After smelting is completed, the hook lock is hung on the lifting ring 9 on the top of the furnace cover 2 to pull it up using the equipment. As the furnace cover 2 is pulled up, the slider mechanism 4 drives the slag scooping net 6 at the bottom of the furnace body 1 to rise together through the chain 5. The slag scooping net 6 salvages the waste slag in the aluminum liquid to the surface during the rising process. As the weight of the waste slag drives the sliding block 42 to shrink in the sliding groove 41 through the chain 5, the slag scooping net 6 is gathered inward into a bag shape, which prevents the waste slag from falling and facilitates subsequent collection.
