[0002] A smelting furnace is a device that melts metal ingots and some scrap metals, adds necessary alloy components, and then smelts them into the required alloy through operations such as slagging and refining.

However, the stirring rod cannot adjust the stirring area between the stirring rod and the molten metal according to the type of molten metal. When the viscosity and density of the molten metal are high, the stirring rod may have uneven stirring due to the small stirring area, which is relatively inconvenient to use. Therefore, we propose a stirring device for a molten metal melting furnace to solve or improve the above problems. Utility Model Content

[0021] 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.

[0022] See also Figure 1-7, including a smelting furnace body 1, a charging bin 3 is fixed on the top of the smelting furnace body 1, the internal space of the charging bin 3 is connected to the internal space of the smelting furnace body 1, an upper partition 4 is slidably installed inside the charging bin 3, a handle is fixed on the surface of the upper partition 4, and the upper partition 4 can be pulled to move by the handle, and a lower partition 5 is slidably installed inside the charging bin 3, the lower partition 5 is located on one side of the bottom of the upper partition 4, a second rack 12 is fixed on one side of the upper partition 4, and a first rack 6 is fixed on one side of the lower partition 5, and a linkage gear 11 is installed inside the charging bin 3 through a rotating shaft, and the linkage gear 11 is meshed and connected with the second rack 12 and the first rack 6, and when the upper partition 4 moves, it will drive the fixed second rack 12 to rotate. The rack 12 moves, and when the second rack 12 moves, it will drive the meshing linkage gear 11 to rotate. When the linkage gear 11 rotates, it will drive the meshing first rack 6 to move. When the first rack 6 moves, it will drive the fixed lower partition 5 to move. When material needs to be added during the process, the upper partition 4 is first pulled to move the upper partition 4 to the side away from the charging bin 3. When the upper partition 4 moves, the lower partition 5 is driven to move through the second rack 12, the linkage gear 11 and the first rack 6, so that the lower partition 5 moves to the side close to the charging bin 3, so that when the upper partition 4 is opened, the lower partition 5 is closed and the charging bin 3 is separated from the smelting furnace body 1. At this time, when the material is placed inside the charging bin 3, the material will The upper partition 4 is closed at this time to open the lower partition 5 and allow the material placed on the top of the lower partition 5 to fall into the interior of the smelting furnace body 1, thereby avoiding the high temperature inside the smelting furnace body 1 escaping when the material is added during the melting process and causing burns to personnel, and reducing the probability of burns when personnel add materials. The driving motor 2 is fixed to the top side of the smelting furnace body 1 through a fixing plate, and the top of the smelting furnace body 1 is located at a position on one side of the driving motor 2 and a top cover is installed through a rotating shaft. The driving rod 10 is fixed to the top of the output shaft of the driving motor 2. The driving motor 2 can drive the driving rod 10 fixed at the top of the output shaft to rotate, and the stirring rod 7 is fixed on the surface of the driving rod 10. When the driving rod 10 rotates, the stirring rod 7 fixed on the surface will be driven to rotate. The scraper 9 is fixed on the surface of the driving rod 10. When the driving rod 10 rotates, the scraper 9 fixed on the surface will be driven to rotate. The distance between one side surface of the scraper 9 and the inner surface of the smelting furnace body 1 is small. When the scraper 9 rotates, the molten liquid on the inner surface of the smelting furnace body 1 on one side can be scraped off from the surface of the smelting furnace body 1 and participate in the stirring, thereby improving the uniformity of stirring. The mixing plate 8 is rotatably installed on the surface of the driving rod 10. When the driving rod 10 rotates, the mixing plate 8 installed on the surface will be driven to rotate. The stirring rod 7, the mixing plate 8 and the scraper 9 are symmetrically arranged in two groups on the surface of the driving rod 10, and the adjustment component A is arranged inside the driving rod 10.

[0023] The adjusting component A includes an adjusting link 14 inserted into the driving rod 10, and the adjusting link 14 can rotate inside the driving rod 10, an adjusting knob 13 sleeved on the surface of one side of the top of the adjusting link 14, a slot is provided on the top side of the driving rod 10, and the adjusting knob 13 is located at the center position of the inner groove of the top side of the driving rod 10, and a limit block 15 is fixed to the inner surface of the adjusting knob 13. The limit block 15 can limit the position of the adjusting knob 13 to prevent the adjusting knob 13 from detaching from the surface of the adjusting link 14. At the same time, when the adjusting knob 13 rotates, the fixed limit block 15 will be driven to rotate, so that the surface of the limit block 15 contacts and squeezes the surface of the adjusting link 14, so that when the adjusting knob 13 rotates, the adjusting link 14 is driven to rotate through the limit block 15, and a limit column 16 fixed to the outer surface of the adjusting knob 13, the driving rod 1 0 is provided with a slot at a position on one side of the bottom of the limit column 16, and the bottom of the adjusting knob 13 and the limit column 16 can be inserted into the inside of the slot. When the limit column 16 is inserted into the slot of the driving rod 10, the position of the fixed adjusting knob 13 can be limited to prevent the adjusting knob 13 from rotating. At the same time, when the position of the adjusting knob 13 is limited, the adjusting knob 13 will limit the position of the adjusting connecting rod 14 through the limit block 15, so that the adjusting connecting rod 14 cannot rotate. The driving gear 17 fixed to one end of the bottom of the adjusting connecting rod 14 will drive the fixed driving gear 17 to rotate when the adjusting connecting rod 14 rotates. The passive gear 18 fixed to one end of the rotating shaft of the mixing plate 8 is meshed and connected with the driving gear 17. When the driving gear 17 rotates, it will drive the meshed passive gear 18 to rotate, and when the passive gear 18 rotates, it will drive the fixed mixing plate 8 to rotate.

[0024] Working principle: when different materials are melted and the stirring area between the mixing plate 8 and the melt needs to be changed, the adjusting knob 13 can be lifted upward to disengage the adjusting knob 13 from the inside of the driving rod 10, and the adjusting knob 13 can be rotated. When the adjusting knob 13 is rotated, the adjusting connecting rod 14 will be driven to rotate, and when the adjusting connecting rod 14 is rotated, the driving gear 17 will be driven to rotate, and when the driving gear 17 is rotated, the passive gear 18 will be driven to rotate, so that the passive gear 18 drives the mixing plate 8 to rotate. After the adjustment of the mixing plate 8 is completed, the adjusting knob 13 and the limit column 16 are pressed again and inserted into the inside of the driving rod 10 to limit the position of the adjusting connecting rod 14, so that the position of the mixing plate 8 is relatively fixed. When the mixing plate 8 rotates, the surface inclination angle will change, thereby changing the stirring area between the mixing plate 8 and the melt. Then, the stirring area between the mixing plate 8 and the melt can be increased or decreased by adjusting the rotation angle of the mixing plate 8, thereby strengthening or weakening the stirring effect on the melt, avoiding the problem of uneven stirring due to a small stirring area, and it is relatively convenient to use.
