Description

Technical Field

[0001] The present invention relates to a device for lifting and conveying molten aluminum, belonging to the technical field of melting furnace equipment. Background Art

[0002] In the production of aluminum alloy melting, lifting and conveying molten aluminum from one position to another is a key link. At present, in order to reduce raw material costs, general equipment uses aluminum scraps and melting furnaces. In actual production, aluminum ingots need to be put into the melting chamber of the furnace, heated and melted. The molten aluminum flows into the holding chamber, aluminum scraps are put into the eddy current chamber, melted and then flow into the holding chamber. After the molten aluminum in the holding chamber is qualified, it flows into the static furnace, and after being refined and qualified, it flows out into the tundish and is transferred to the casting process. After retrieval, it is found that the Chinese patent with the publication number CN212931018U discloses an automatic water discharging structure for a melting furnace or a holding furnace. In this patent, a plug blocks the discharging end of the molten aluminum outflow channel. When it is necessary to discharge the molten aluminum, the piston rod of the air cylinder extends, and the plug is lifted upward through the connecting piece and the connecting rod. The connecting rod and the plug slide upward along the rolling guide rail, and the plug moves away from the discharging end of the molten aluminum outflow channel, and the molten aluminum flows out of the melting furnace or the holding furnace through the outflow channel and the chute; when it is necessary to stop the outflow of the molten aluminum, the piston rod of the air cylinder shortens, the connecting rod and the plug move downward, and the plug blocks the discharging end of the outflow channel again, stopping the outflow of the molten aluminum. However, in this patent, during the process of pulling out the plug, the molten aluminum is prone to splash, which is likely to cause potential safety hazards; frequent plugging and unplugging of the plug is likely to cause wear of the plug and requires frequent replacement, increasing production costs.

[0028] To make the content of this invention easier to understand, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0029] like Figure 1-5 As shown, an aluminum liquid lifting and conveying device includes:

[0030] Mobile base 1;

[0031] The melting furnace 2 is mounted on the frame. The melting furnace 2 is provided with a melting chamber 21 and a liquid rising channel 22. The melting chamber 21 is suitable for storing molten aluminum liquid. The liquid rising channel 22 is connected to the melting chamber 21. The top of the melting furnace 2 is provided with a downwardly inclined liquid outlet trough 23.

[0032] The aluminum liquid lifting assembly includes a lifting device and a rotating device. The lifting device is installed on the movable base 1. The rotating device includes a rotary motor 31, a connecting shaft 32 and an impeller 33. The rotary motor 31 is installed on the lifting device. One end of the connecting shaft 32 is connected to the movable end of the rotary motor 31. The impeller 33 is installed on the other end of the connecting shaft 32 and is disposed in the liquid lifting channel 22.

[0033] The lifting device is adapted to drive the rotating device to move up and down so that the impeller 33 is in a suitable position, and the rotating motor 31 is adapted to drive the impeller 33 to rotate so that the aluminum liquid in the liquid rising channel 22 rises to the liquid outlet tank 23 and flows out.

[0034] Specifically, such as Figure 1-4 As shown, the lifting device includes a fixed bracket 41, a movable bracket 42, and a lifting drive mechanism. The fixed bracket 41 is mounted on the movable base 1, the movable bracket 42 is slidably mounted on the fixed bracket 41, the rotary motor 31 is mounted on the movable bracket 42, and the lifting drive mechanism is mounted on the fixed bracket 41. The lifting drive mechanism is adapted to drive the movable bracket 42 to slide on the fixed bracket 41.

[0035] Specifically, such as Figure 1-4 As shown, the lifting drive mechanism includes a lifting motor 431, a lifting bracket 432, and a lifting base 433. The lifting bracket 432 is mounted on a fixed bracket 41, and the lifting motor 431 is mounted on the top of the lifting bracket 432. The lifting bracket 432 is also provided with a lifting groove 432A. The lifting base 433 is movably disposed in the lifting groove 432A. Vertical grooves 432B are also provided on both sides of the lifting bracket 432. The vertical grooves 432B are connected to the lifting groove 432A. The lifting motor 431 is connected to the lifting base 433 through a screw and nut pair. The screw 51 in the screw and nut pair is connected to the movable end of the lifting motor 431, and the nut in the screw and nut pair is connected to the lifting base 433.

[0036] The movable support 42 has a movable through groove 421 at one end. The movable support 42 is sleeved on the lifting support 432 through the movable through groove 421. Two connectors 421A are provided in the movable through groove 421. The connectors 421A are adapted to pass through the vertical groove 432B and connect to the lifting base 433.

[0037] In this embodiment, the connector 421A can be a bolt. The connector 421A is used to firmly connect the movable bracket 42 and the lifting base 433. When the lifting motor 431 is working, due to the action of the lead screw and nut pair, the lifting base 433 will move up and down along the lifting groove 432A. The connection between the connector 421A and the lifting base 433 through the vertical groove 432B allows the movable bracket 42 to move up and down accordingly as the lifting base 433 moves.

[0038] Specifically, such as Figure 3-4 As shown, the lifting bracket 432 is also equipped with four guide rails 432C;

[0039] The movable channel 421 is also provided with four movable wheels 421B. The four movable wheels 421B are suitable for sliding on the corresponding guide rails 432C. The cooperation between the guide rails 432C and the movable wheels 421B provides a stable sliding path for the movable bracket 42, ensuring the smooth lifting and lowering of the movable bracket 42, and making the lifting and lowering of the rotating device smoother.

[0040] Specifically, such as Figure 5 As shown, the bottom of the melting chamber 21 is a stepped bottom surface, which divides the melting chamber 21 into a shallow liquid zone 61 and a deep liquid zone 62. The liquid rising channel 22 is located above the deep liquid zone 62.

[0041] Specifically, such as Figure 1-2 As shown, the bottom of the movable base 1 is provided with four first rollers 11 suitable for sliding.

[0042] Specifically, such as Figure 1-3 As shown, the movable base 1 is also equipped with a handle 12 to facilitate the movement of the movable base 1.

[0043] Specifically, such as Figure 1-3 As shown, the movable base 1 is also provided with two auxiliary support arms 13. The auxiliary support arms 13 are provided with second rollers 131 and support components. The support components include a drive cylinder 132 and a support base 133. The drive cylinder 132 is mounted on the auxiliary support arms 13. The support base 133 is connected to the movable end of the drive cylinder 132. When the movable base 1 moves to the predetermined position, the drive cylinder 132 is adapted to drive the support base 133 to move downward to press against the ground.

[0044] Specifically, the connecting shaft 32 is a graphite connecting shaft;

[0045] Impeller 33 is a graphite impeller. The graphite connecting shaft 32 and the graphite impeller 33 can withstand the high temperature and corrosive environment of molten aluminum. At the same time, the connecting shaft 32 and the impeller 33 are less likely to undergo chemical reactions when in contact with molten aluminum, thereby reducing pollution and extending the service life of the equipment.

[0046] In this embodiment, the smelting furnace 2 is fixed at a specific position in the working area. The movable base 1 is moved to the appropriate position by the handle 12, so that the aluminum liquid lifting assembly is above the smelting furnace 2. The lifting device is started, and the movable support 42 and the rotating device are driven to rise by the lifting drive mechanism, so that the impeller 33 is in the appropriate position in the liquid lifting channel 22. At this time, the impeller 33 is immersed in the aluminum liquid in the liquid lifting channel 22.

[0047] Start the rotary motor 31 to drive the impeller 33 to start rotating. The rapid rotation of the impeller 33 generates a siphon that causes the aluminum liquid level in the liquid rising channel 22 to rise to the liquid outlet tank 23. Then the aluminum liquid flows out through the liquid outlet tank 23 and is transported to other processing equipment or storage molds for the next step of operation.

[0048] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the present invention.
