Description

Technical Field

[0001] The present invention relates to the field of aluminum casting production, and particularly relates to a receiving device for aluminum casting. Background Art

[0002] The melting furnace (melting device) for aluminum casting is prone to the problem of aluminum liquid leakage. When aluminum liquid leaks, all the aluminum liquid in the melting furnace needs to be discharged. However, in actual operation, due to the high temperature of the aluminum liquid, it is easy to cause damage to the ground. At the same time, since the discharged aluminum liquid needs to be recycled for use after cooling, the traditional implementation scheme has the problem of inconvenient operation in the recycling of the solidified aluminum liquid after cooling. Summary of the Invention

[0003] To solve the above problems, the present invention provides a receiving device for aluminum casting.

[0004] The technical solution adopted by the present invention is specifically as follows.

[0005] A receiving device for aluminum casting, characterized in that it includes a melting device, and outside the aluminum liquid discharge port at the bottom of the melting device, there is a receiving groove for receiving the discharged aluminum liquid, and the bottom of the receiving groove is arranged in a separated state from the ground.

[0006] Specifically, a guiding device is provided at the aluminum liquid discharge port, and the guiding device is used to guide the aluminum liquid into the receiving groove.

[0007] The height of the opening of the receiving groove is less than the height of the aluminum liquid discharge port. <OP>

[0008] The discharging direction of the aluminum liquid discharge port is obliquely downward and points into the receiving groove.

[0009] The wall of the receiving groove is made of brick material and yellow mud.

[0010] A heat preservation device for heat-preserving the aluminum liquid is arranged beside the melting device. The heat preservation device is assembled on a support frame, and the receiving groove extends into the support frame below the heat preservation device.

[0011] The receiving groove is in a "convex" shape. The direction of the distance between the melting device and the heat preservation device is consistent with the length direction of the receiving groove. The groove section with a smaller width of the upper groove of the receiving groove is located between the melting device and the heat preservation device, and the groove section with a larger width of the upper groove of the receiving groove is located below the heat preservation device.

[0012] A brick material layer is laid below the receiving groove for overhead. Horizontally arranged square steel pipes are arranged at intervals in a discharging state on the brick material layer. The square steel pipes are arranged at intervals along the length direction of the receiving groove. The length direction of the square steel pipes is consistent with the width direction of the receiving groove. A bottom plate of the groove is laid on the square steel pipes, and the bottom plate of the groove constitutes the bottom of the receiving groove. The periphery of the bottom plate of the groove is made of brick material and yellow mud to form the wall of the groove.

[0013] The depth of the tank section near the aluminum molten outlet gradually decreases along the flow direction of the aluminum molten material in the receiving tank.

[0014] Vertically arranged dividing steel plates are installed inside the receiving groove. The length direction of the dividing steel plates is consistent with the width direction of the receiving groove. The dividing steel plates are spaced apart along the length direction of the receiving groove. The height of the dividing steel plates is less than the depth of the receiving groove. The two ends of the dividing steel plates are embedded and fixed in the groove wall of the receiving groove. The bottom edge of the dividing steel plate abuts against the upper surface of the bottom steel plate of the groove. A square notch is provided in the middle of the upper side of the dividing steel plate. The spacing between adjacent dividing steel plates matches the length of a brick. Bricks are placed between adjacent dividing steel plates for support.

[0015] The above-mentioned solution provided by the present invention can effectively avoid damage to the workshop floor caused by the discharged molten aluminum. The recovery operation after the molten aluminum solidifies is simple, the implementation cost of the device is low, and it can be re-stacking after use. Attached Figure Description

Detailed Implementation

[0022] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention. Existing structures not described in detail in this invention are implemented according to existing technical solutions.

[0023] like Figures 1-4As shown, a receiving device for aluminum casting includes a smelting device 20 (smelting furnace). A receiving trough 10 for receiving the discharged molten aluminum is provided outside the aluminum discharge port 21 at the bottom of the smelting device 20. The bottom of the receiving trough 10 is separated from the ground. Specifically, a guiding device is provided at the aluminum discharge port 21 to guide the molten aluminum into the receiving trough 10. The height of the opening of the receiving trough 10 is less than the height of the aluminum discharge port 21. The discharge direction of the aluminum discharge port 21 is obliquely downwards towards the receiving trough 10. The wall 11 of the receiving trough 10 is constructed of bricks and yellow mud, where yellow mud refers to the yellow mud mortar used in traditional adobe house construction. A heat preservation device 30 for heat preservation of molten aluminum or a casting device for casting is provided on the side of the smelting device 20. The heat preservation device 30 or the casting device is mounted on a support frame. The receiving groove 10 extends into the support frame provided below the heat preservation device 30 or the casting device. Figure 1 The outlines of the smelting device 20 and the heat preservation device 30 are only simplified representations of the devices and do not represent the actual structure of the devices.

[0024] The above-mentioned solution provided by the present invention can effectively avoid damage to the workshop floor caused by leaked molten aluminum. Furthermore, the recovery operation after the molten aluminum solidifies is simple, the implementation cost of the entire solution is low, and it can be re-stacking after use.

[0025] The receiving trough 10 is convex in shape. The spacing between the smelting device 20 and the heat preservation device 30 is aligned with the length of the receiving trough 10. The narrower section of the receiving trough 10 is located between the smelting device 20 and the heat preservation device 30, while the wider section is located below the heat preservation device 30. A brick layer 15 is laid on the ground below the receiving trough 10 for support. Horizontal square steel pipes 14 are arranged at intervals on the brick layer 15, with their length aligned with the width of the receiving trough 10. A bottom steel plate 12 is laid on the square steel pipes 14, forming the bottom of the receiving trough. The perimeter of the bottom steel plate 12 is constructed of bricks and mortar to form the trough walls 11. The depth of the tank section near the aluminum outlet 21 on the tank wall 11 gradually decreases along the flow direction of the aluminum in the receiving tank 10. Vertically arranged partition steel plates 13 are provided in the receiving tank 10. The length direction of the partition steel plates 13 is consistent with the width direction of the receiving tank 10. The partition steel plates 13 are spaced apart along the length direction of the receiving tank 10. The height of the partition steel plates 13 is less than the depth of the receiving tank 10. The two ends of the partition steel plates 13 are embedded and fixed in the tank wall 11 of the receiving tank 10. The bottom edge of the partition steel plates 13 abuts against the upper surface of the bottom steel plate 12. A square notch 131 is provided in the middle of the upper side of the partition steel plates 13. The spacing between adjacent partition steel plates 13 matches the length of a brick. Bricks 16 are placed between adjacent partition steel plates for support.

[0026] In the above scheme, the space below the insulation device 30 is utilized to provide sufficient tank volume for receiving large amounts of molten aluminum. The bricks placed between the separating steel plates 13 prevent the molten aluminum from impacting the steel plates, causing deformation that could crack or collapse the tank wall 11, thus improving the reliability and stability of the receiving tank 10 in receiving molten aluminum. After the molten aluminum solidifies, the tank wall 11 can be removed, and the separating steel plates 13 can be disassembled piece by piece. This allows for convenient and rapid recycling of the solidified aluminum material between the separating steel plates, greatly simplifying the aluminum recycling operation, significantly reducing costs and improving efficiency. Furthermore, if the receiving tank 10 is damaged, it can be easily reassembled by workers, resulting in low implementation costs.

[0027] In addition, the present invention also provides a nozzle on the molten aluminum outlet 21, which changes the discharge direction of the molten aluminum, that is, the discharge direction of the molten aluminum outlet 21 is obliquely downward pointing away from the side of the smelting device 20. The height of the molten aluminum outlet 21 is greater than the height of the opening of the receiving tank 10, therefore a guiding device 40 for guiding the molten aluminum is provided between the molten aluminum outlet 21 and the receiving tank 10. The guiding device 40 is installed at an angle on the smelting device 20. The guiding device 40 includes two side plates 41 connected by connecting plates. The connecting plates include plates A, B, and C, all arranged perpendicular to the side plates 41. Plates A and B are connected by plate C 43. Plate A 42 is located in the middle of side plate 41, with its height aligned with that of side plate 41, but its height is less than that of side plate 41. The lower edge of plate A 42 is flush with the lower edge of side plate 41. Plates A 42 and B 44 are arranged perpendicularly. Plate C 43 is arranged at an angle, with its angle matching the discharge direction of the molten aluminum outlet 21. Plate B 44 is located above plate A 42, extending from the edge of plate C 43 towards the side closest to the smelting device 20. The thickness of plate B 44 is aligned with the height of side plate 41. A first oblong hole 45 is provided in a first region on the side plate 41. The length direction of the first oblong hole 45 is consistent with the width direction (x direction) of the side plate 41, and the first oblong holes 45 are arranged in an array in the first region. A second oblong hole 46 is provided in a second region on the side plate 41. The length direction of the second oblong hole 46 is consistent with the height direction (y direction) of the side plate 41, and the second oblong holes 46 are arranged in an array in the second region. The first region is the outer side of plate A 42 and the lower side of plate B 44 on the side plate 41 away from the melting device 20, located within the receiving groove 10. The second region is the inner side of plate A 42 and the upper side of plate B 44 on the side plate 41 near the melting device 20. Preferably, the height of plate A 42 is set to match half the height of the side plate 41. The guide device 40 is installed at an angle, with a smaller height at the end away from the melting device 20. The guide device 40 is made of steel. The discharge end of the molten aluminum outlet 21 extends into the conveying device 40, and the height of the discharge end of the molten aluminum outlet 21 is greater than the height of plate B 44. The side plate 41 of the conveying device, which is away from the melting device 20, extends (is installed) into the receiving groove 10. The conveying device is made of steel.

[0028] The aforementioned guiding device 40 can reliably guide molten aluminum, allowing it to flow reliably into the receiving tank 10. The design of the first and second oblong holes can improve the safety of molten aluminum conveying and unloading.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
