[0002] An aluminum alloy melting and casting furnace is a type of industrial equipment specifically designed for melting and casting aluminum alloys. This equipment heats the aluminum alloy raw material above its melting point, turning it into a liquid state for casting and pouring. Aluminum alloy melting and casting furnaces are widely used in a variety of fields, including aerospace, automotive manufacturing, machining, and construction.

[0003] Most aluminum alloy melting furnaces only have a single heating function, which leads to local overheating or uneven heating of the aluminum alloy raw materials when melting, affecting the melting effect. In addition, relying solely on natural convection, it is difficult to ensure that the aluminum alloy raw materials are fully mixed during the melting process, which may lead to uneven alloy composition and affect the quality of the final casting. In addition, due to uneven heating and mixing, it takes longer to complete the melting and mixing process, resulting in low production efficiency.

[0004] Therefore, a kind of aluminum alloy melting and casting furnace is particularly needed to solve the above-mentioned problems. Utility Model Content

[0021] The technical solution of the present utility model will be further described below with reference to the accompanying drawings.

[0022] Example: An aluminum alloy melting furnace, see Figure 1-Figure 5 As shown, it includes a shell 1, a material port 101, a support frame 3, a fixing ring 5, a heating tube 6, a controller 7, a connecting plate 10 and a third motor 11. A square rubber block is provided at the bottom of the support frame 3 to prevent the support frame 3 from moving during use. A connecting plate 10 is rotatably connected between the upper parts of the two support frames 3. The fixing rings 5 distributed left and right are rotatably connected between the two connecting plates 10. The two fixing rings 5 are connected to the shell 1 by bolts. The material port 101 is connected to the center position of the right side of the outer shell 1 by welding. The heating tube 6 is connected to the cavity on the inner wall of the shell 1 by bolts. , and the heating tube 6 is a spiral design, evenly distributed in the cavity of the inner wall of the shell 1, which can improve the heating efficiency and heating uniformity. The shell 1 is connected to a controller 7 electrically connected to the heating tube 6 by bolts, and the rear side of the controller 7 is located in the cavity of the inner wall of the shell 1, and the front side is located outside the shell 1 for easy operation. The upper part of the front support frame 3 is connected to the third motor 11 by bolts, and the output shaft of the third motor 11 is fixedly connected to the connecting plate 10. It also includes a rotating mechanism and a stirring mechanism. A rotating mechanism is provided between the connecting plate 10 and the left fixed ring 5, and a stirring mechanism is provided on the shell 1.

[0023] See Figure 2 、 Figure 3 and Figure 5 As shown, the rotating mechanism includes a ring gear 4, a gear 12 and a fourth motor 13. The outer ring of the left fixing ring 5 is connected to the ring gear 4 by welding, and the fourth motor 13 is connected to the left front side of the lower inner part of the connecting plate 10 by bolts. The output shaft of the fourth motor 13 is connected to the gear 12 by a key connection, and the gear 12 is meshed with the ring gear 4 of equal thickness.

[0024] See Figure 1-Figure 2 As shown, the stirring mechanism includes a first motor 2 and a stirring rod 14. The first motor 2 is connected to the center position of the left side of the outer shell 1 by means of bolts. The output shaft of the first motor 2 penetrates into the interior of the outer shell 1 and is connected to the stirring rod 14 by means of a key connection.

[0025] See Figure 3-Figure 4 As shown, it also includes a second motor 8 and a filter disc 9. The second motor 8 is connected to the front right side of the outer shell 1 by means of bolts, and the filter disc 9 is connected to the output shaft of the second motor 8 by means of a key connection, and the filter disc 9 is located to the right of the material port 101 and is in contact with it.

[0026] First, the staff starts the second motor 8, so that its output shaft drives the filter disc 9 to rotate and open the material port 101. After opening, the second motor 8 is closed, and then the aluminum alloy raw material is fed into the shell 1 through the material port 101. After the feeding is completed, the second motor 8 is started again, and its output shaft is controlled to reverse, driving the filter disc 9 to reverse and close the material port 101 to prevent the aluminum alloy raw material from leaking. Then the second motor 8 is closed again, and the controller 7 is operated to start the heating tube 6, and the heating temperature is set to heat the aluminum alloy raw material in the shell 1 so that the aluminum alloy raw material gradually melts. Then the fourth motor 13 and the first motor 2 are started, and the output shaft of the fourth motor 13 drives the gear 12 to rotate, so that the gear 12 engages with the ring gear 4, and the ring gear 4 drives the left fixing ring 5 to rotate, so that the left fixing ring 5 and the right fixing ring 5 work together to drive the shell 1 to rotate. , making the heating more uniform, the output shaft of the first motor 2 drives the stirring rod 14 to rotate, stirring the aluminum alloy raw material in the outer shell 1, ensuring that the melted aluminum alloy raw material is fully mixed during the heating process. During heating, the excess gas in the outer shell 1 can be filtered through the filter disk 9 and discharged to the outside, thereby avoiding the internal temperature of the outer shell 1 being too high and the air pressure being too high. When the aluminum alloy raw material is completely melted and reaches the required temperature, the heating tube 6, the fourth motor 13 and the first motor 2 are turned off. Finally, the container is placed under the connecting plate 10, and the third motor 11 is started so that its output shaft drives the connecting plate 10 to rotate 90 degrees, so that the material port 101 is downward for discharging. When discharging, the filter disk 9 filters out impurities in the aluminum alloy raw material to improve the purity of the aluminum alloy raw material. After discharging is completed, repeat the above steps to open the material port 101 and discharge impurities.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
