Description

Technical Field

[0001] The utility model relates to the technical field related to metal smelting, and more specifically to a cooling device for aluminum-manganese alloy casting. Background Art

[0002] Aluminum-manganese alloy is an alloy with strong deoxidation ability. Its specific gravity is about twice that of metallic aluminum. During deoxidation alloying, it can increase the aluminum yield, thereby reducing the consumption of metallic aluminum. It also simplifies the deoxidation process and facilitates operation.

[0003] Patent authorization number CN211661068U discloses a cooling device for the production of cast aluminum alloy ingots. The device comprises an isolation room with multiple exhaust vents on the top; a cooling water pipeline is laid around the periphery of the isolation room; one end of the pipeline is the cooling water inlet, and the cooling water is discharged from the outlet end of the pipeline after circulation; a cooling table is installed inside the isolation room to support the aluminum material to be cooled. The upper end of the cooling table is composed of multiple slats with gaps between the slats, and the bottom of the cooling table has a water outlet; a water collection cover is installed below the cooling table. The large opening of the water collection cover is adapted to the size of the cooling table and is fixedly connected to the lower end of the isolation room. The small opening of the water collection cover is connected to the drainage pipeline that penetrates the isolation room and extends to the outside of the isolation room; and multiple spray heads are installed on the inner wall of the isolation room above the cooling table. The spray heads are connected to the cooling water pipeline through spray branches. The device can quickly and effectively cool the aluminum material, with high cooling efficiency and ideal cooling effect.

[0004] However, the slag produced during the metal cooling process is of various types, including non-ferrous metal slag, etc. These slags are formed during the smelting process and contain multiple elements, which are of great significance to the environment and resource recovery. Since the patent authorization number CN211661068U does not have the function of recycling the metal slag produced during the cooling process, the cooling water is directly discharged, which will cause environmental pollution. Therefore, we proposed a cooling device for aluminum-manganese alloy casting to solve the above-mentioned problems. Utility Model Content

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] Example:

[0034] See also Figure 1-6 A cooling device for aluminum-manganese alloy casting comprises a cooling pool 1 and supporting legs symmetrically fixedly connected to the bottom edge of the cooling pool 1. An arc-shaped groove 2 is integrally formed at the bottom midline of the cooling pool 1. An auger 3 is rotatably connected to the inner side of the arc-shaped groove 2, and the outer diameter of the auger 3 matches the inner diameter of the arc-shaped groove 2. A reduction motor 4 with a power output end connected to the auger 3 is installed on the outer side of the cooling pool 1. A slag discharge pipe 5 is provided at the end of the cooling pool 1 away from the reduction motor 4 and is conductively connected to the arc-shaped groove 2.

[0035] One end of the arc-shaped slot 2 close to the reduction motor 4 is connected to a drain pipe 6, and a filter screen 15 is installed at the top of the drain pipe 6;

[0036] The side wall of the cooling pool 1 is connected to a water pumping pipe 8, and a filter 9 is installed on the water pumping pipe 8;

[0037] A coiled heat exchanger 11 is installed on one side of the water pumping pipe 8. A water pump 12 is installed on the outer wall of the coiled heat exchanger 11 through a bracket, and the input end of the water pump 12 is connected to the water pumping pipe 8. The root of the coiled heat exchanger 11 is conductively connected to a hot water inlet pipe 13, and the hot water inlet pipe 13 is conductively connected to the output end of the water pump 12. The top of the coiled heat exchanger 11 is conductively connected to a cooling water outlet pipe 14, and the cooling water outlet pipe 14 is conductively connected to the cooling pool 1;

[0038] It should be noted that when the cooling device for aluminum-manganese alloy casting is in use, the aluminum-manganese alloy after smelting is placed in a cooling pool 1 filled with coolant, so that the aluminum-manganese alloy is completely immersed in the coolant. The metal slag produced by the alloy during the cooling process will be precipitated in the arc groove 2. At the same time, the water pump 12 is turned on to pump the coolant in the cooling pool 1 through the pumping pipe 8 to the serpentine heat exchanger 11, and the metal slag in the coolant is filtered through the filter 9. At the same time, cold water is passed into the serpentine heat exchanger 11 to quickly cool the cooling water. After that, the cooling water is transported to the cooling pool 1 through the cooling water outlet pipe 14 and circulated to improve the cooling effect of the aluminum-manganese alloy. After cooling is completed, the coolant is discharged through the drain pipe 6, and the metal slag is intercepted by the filter 15. The reduction motor 4 is started to drive the auger 3 to rotate, and the metal slag located on the inner side of the arc groove 2 is discharged through the slag discharge pipe 5. The metal slag can be collected and processed in a centralized manner to reduce pollution to the environment.

[0039] like Figure 1 As shown, pressure gauges 10 installed on the outer wall of the water pumping pipe 8 are provided on both sides of the filter 9, and the detection end of the pressure gauge 10 extends to the inner cavity of the water pumping pipe 8;

[0040] It should be noted that, during the process of the filter 9 filtering the metal slag in the cooling water, the readings of the two pressure gauges 10 are manually observed. When the pressure difference between the two pressure gauges 10 is too large, the filter 9 needs to be cleaned in time to ensure the flow rate during the coolant circulation process.

[0041] like Figure 4 As shown, a connecting shaft head is welded to one end of the auger 3 close to the reduction motor 4, and the connecting shaft head extends to the outside of the cooling pool 1 and is connected to the power output end of the reduction motor 4 through a coupling;

[0042] A seal is installed at the joint between the cooling pool 1 and the connecting shaft head;

[0043] It should be noted that while ensuring that the power output by the reduction motor 4 can be normally transmitted to the auger 3, leakage of the coolant can be effectively prevented.

[0044] like Figure 1 、 Figure 2 As shown, a first stop valve is installed at the slag discharge pipe 5, and a second stop valve is installed at the end of the drain pipe 6;

[0045] It should be noted that by opening the first stop valve and the second stop valve, waste water and waste residue can be discharged separately.

[0046] like Figure 6 As shown, both sides of the top of the arc-shaped groove 2 are provided with guide inclined surfaces 7 integrally formed with the cooling pool 1;

[0047] It should be noted that the provision of the guiding inclined surface 7 plays a good guiding role on the metal slag, so that the metal slag can be gathered in the arc-shaped groove 2.

[0048] like Figure 1 As shown, the inner cavity of the cooling pool 1 is filled with coolant, and the liquid level of the coolant is above the water pumping pipe 8;

[0049] It should be noted that this is beneficial to the recycling of the coolant.

[0050] During use: the aluminum-manganese alloy after smelting is placed in a cooling pool 1 filled with coolant, so that the aluminum-manganese alloy is completely immersed in the coolant. The metal slag produced by the alloy during the cooling process will be precipitated in the arc groove 2. At the same time, the water pump 12 is turned on to pump the coolant in the cooling pool 1 through the pumping pipe 8 to the serpentine heat exchanger 11, and the metal slag in the coolant is filtered through the filter 9. At the same time, cold water is passed into the serpentine heat exchanger 11 to quickly cool the cooling water. After that, the cooling water is transported to the cooling pool 1 through the cooling water outlet pipe 14 and circulated to improve the cooling effect of the aluminum-manganese alloy. After cooling is completed, the coolant is discharged through the drain pipe 6, and the metal slag is intercepted by the filter 15. The reduction motor 4 is started to drive the auger 3 to rotate, and the metal slag located on the inner side of the arc groove 2 is discharged through the slag discharge pipe 5.

[0051] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
