Description

Technical Field

[0001] This utility model relates to the field of natural gas melting furnace technology, specifically to an aluminum alloy tilting natural gas melting furnace. Background Technology

[0002] In the field of aluminum alloy processing, melting furnaces are key equipment for melting solid aluminum alloy raw materials into liquid state. They are widely used in production processes such as casting and die casting. Currently, most aluminum alloy melting furnaces use natural gas as fuel.

[0003] However, existing natural gas melting furnaces still have some problems in actual use. The furnace body of traditional fixed melting furnaces is stationary. When the molten aluminum is discharged, due to the height difference between the furnace bottom and the outlet, the molten aluminum is easy to remain at the bottom of the furnace. This not only wastes raw materials, but also requires frequent cleaning of the slag at the bottom of the furnace, which increases maintenance costs and downtime. Meanwhile, different specifications of casting molds or die-casting equipment have different requirements for the discharge speed and landing point of aluminum liquid. The outlet position of the fixed furnace body is fixed, which is difficult to adapt to diverse production needs. It is easy for aluminum liquid to splash or the flow rate to be unstable, which affects the quality of castings.

[0004] Therefore, we propose an aluminum alloy tilting natural gas melting furnace to solve the above problems. Utility Model Content

The lower ends of the two inner plates are fixedly fitted with crossbars. The rod walls of the crossbars are rotatably fitted with push plates. A drive rotation mechanism for driving the crossbars to move is provided between the push plates and the bottom plate.

[0008] Preferably, the drive rotation mechanism includes a drive screw and a motor. A groove is provided on the top of the base plate. The drive screw is rotatably disposed in the groove and threaded through the push plate. The motor is fixedly disposed on the outer wall of the base plate, and the end of the output shaft passes through the groove and is fixedly connected to the drive screw. Two symmetrically arranged guide rods are fixedly disposed in the groove, and the guide rods are slidably disposed in the push plate.

[0018] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0019] This utility model discloses an aluminum alloy tilting natural gas melting furnace.

[0020] This utility model provides, for example Figure 1-3 The aluminum alloy tilting natural gas melting furnace shown includes a base plate 1 and a melting furnace 2. The bottom of the melting furnace 2 is connected to a discharge pipe 18, and a discharge valve 19 is fixedly sleeved on the outer wall of the discharge pipe 18. Two symmetrically arranged first support frames 3 are fixedly installed on the top of the base plate 1. A second support frame 4 is fixedly installed on the upper ends of the two first support frames 3. A rotating shaft 5 is rotatably inserted through the upper ends of both sides of the second support frame 4. A support sleeve 17 is fixedly inserted through the upper ends of both sides of the second support frame 4. The rotating shaft 5 is rotatably installed inside the support sleeve 17. The melting furnace 2 is fixedly installed between the two rotating shafts 5. Both rotating shafts 5 are fixedly fitted with sleeve plates 6. The lower end of the sleeve plate 6 is slidably fitted with an inner plate 7. The lower ends of the two inner plates 7 are jointly fixed with a crossbar 8. The wall of the crossbar 8 is rotatably fitted with a push plate 9. The push plate 9 is L-shaped and has a rotating hole 16 inside to cooperate with the rotation of the crossbar 8. A drive rotation mechanism for driving the crossbar 8 to move is provided between the push plate 9 and the base plate 1. The drive rotation mechanism includes a drive screw 10 and a motor 11. The top of the base plate 1 has a groove. The drive screw 10 is rotatably located in the groove and threaded through the push plate 9. The motor 11 is fixedly located on the outer wall of the base plate 1, and the end of the output shaft passes through the groove and is fixedly connected to the drive screw 10. Two symmetrically arranged guide rods 12 are fixedly located in the groove and are slidably located in the push plate 9.

[0021] In order to limit the relative movement distance of the inner plate and the outer plate when the inner plate and the inner plate drive the rotating shaft and the melting furnace to rotate and tilt, such as Figure 2-3 As shown, the bottom of the sleeve plate 6 is provided with a sliding groove 13 that slides with the inner plate 7. The outer wall of the sleeve plate 6 is provided with a strip hole 14, which is connected to the sliding groove 13. A slide rod 15 slides through the strip hole 14 and is fixedly connected to the inner plate 7.

[0022] Working principle: When in use, aluminum alloy raw materials are placed in melting furnace 2 and heated by natural gas combustion to melt the raw materials. When it is necessary to pour the molten aluminum, motor 11 is started. The output shaft of motor 11 drives the drive screw 10 to rotate in the groove of the base plate 1. The drive screw 10 is threaded with the push plate 9. At the same time, the push plate 9 slides along the guide rod 12, so that the push plate 9 moves horizontally in the groove. When the push plate 9 moves, it drives the crossbar 8 to move synchronously through the rotating hole 16. The crossbar 8 pulls the two inner plates 7. The inner plates 7 slide along the moving groove 13 of the sleeve plate 6. The slide rod 15 slides synchronously in the strip hole 14, guiding and limiting the relative movement of the sleeve plate 6 and the inner plates 7. During the movement of the inner plate 7, the sleeve plate 6 is driven to rotate around the pivot 5. The pivot 5 rotates within the support sleeve 17 of the second support frame 4, thereby causing the melting furnace 2 to tilt synchronously with the pivot 5. By controlling the forward and reverse rotation and running time of the motor 11, the moving distance of the push plate 9 can be precisely adjusted, thereby controlling the tilt angle of the melting furnace 2. After tilting to a suitable angle, the discharge valve 19 is opened, and the molten aluminum is discharged through the discharge pipe 18. When reset is required, the motor 11 reverses, driving the screw 10 to move the push plate 9 in the opposite direction, so that the melting furnace 2 returns to the initial position.

[0023] The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
