Description

Technical Field

[0001] This invention relates to the field of aluminum ingot production technology, specifically to a steam treatment device for water cooling of aluminum ingots. Background Technology

[0002] The aluminum ingot production process involves injecting molten aluminum into a mold via an aluminum distributor. The mold is integrated onto a conveyor chain. The aluminum ingot is shaped by cooling and then unloaded and stacked by a palletizing robot, thus realizing an automated production line for conveying, cooling, shaping, unloading, and palletizing.

[0003] Aluminum ingots are typically cooled by spray cooling, bottom water cooling, and air cooling. Spray cooling is faster and is mainly used for large-scale aluminum ingot production. Before water cooling, the aluminum ingot needs to be naturally cooled to form a preliminary shape before spray cooling is accelerated. However, the aluminum ingot is still at a high temperature at this time, and direct contact with water will generate a large amount of steam. This will affect the internal environment of the factory, and the steam will liquefy on the steel beams inside the factory, which will easily cause the steel beams to rust. Summary of the Invention

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0030] Example 1: Please refer to Figures 1 to 8The present invention provides a technical solution: a steam treatment device for water cooling of aluminum ingots, including a conveyor chain 1, a mold 11 and a frame 12. A housing 13 is fixedly installed on the frame 12. A first fan 2 is fixedly installed on one side of the housing 13. A condensation pipe 21 is fixedly installed on the housing 13. The first fan 2 and a suction pipe 22 are fixedly installed at both ends of the condensation pipe 21, respectively. A spray pipe 14 is provided inside the housing 13, and the suction pipe 22 is located above the spray pipe 14.

[0031] An inclined step 3 and a collection pool 31 are respectively provided on both sides of the condensation pipe 21, and a condensation plate 33 is provided above the inclined step 3.

[0032] A second fan 4 is fixedly installed on the top of the outer casing 13. A first air distribution duct 41 is provided at the air outlet of the second fan 4, and the first air distribution duct 41 is located above the condenser plate 33.

[0033] A purification box 5 is fixedly installed inside the condensate pipe 21. Screws 52 are provided on both the left and right sides of the purification box 5. A partition 53 is provided on one side of the screw 52, ​​and there is a gap between the end of the partition 53 and the inner wall of the purification box 5. A first through groove 54 is provided on both the purification box 5 and the partition 53.

[0034] Specifically, by connecting the water pipe to the spray pipe 14, the aluminum ingot is sprayed after it is initially cooled in the mold 11, thereby accelerating the cooling. When the sprayed water droplets come into contact with the initially cooled but still hot aluminum ingot, a large amount of steam will be generated, which will affect the internal environment of the factory. The steam adheres to the steel beams inside the factory and liquefies, which can easily cause the steel beams to rust.

[0035] In this invention, by activating the condenser pipe 21 to draw air, a negative pressure is generated inside the suction pipe 22, thereby drawing steam into the inner cavity of the condenser pipe 21. When the steam enters the inner cavity of the condenser pipe 21, it comes into contact with the condenser plate 33, which condenses the steam and liquefies it. The liquefied water drips from the condenser plate 33, and part of it enters the collection tank 31 through the inclined step 3 and is collected. The bottom of the collection tank 31 is also provided with a drain outlet 32. By connecting the drain pipe to the drain outlet 32, the water in the collection tank 31 can be drained. The other part of the water drips onto the aluminum ingot through the suction pipe 22, cooling the aluminum ingot.

[0036] Furthermore, when cooling water comes into contact with aluminum ingots, it produces alumina dust mixed in with the steam. This dust diffuses with the steam and is harmful if inhaled. Therefore, the extracted steam needs to be purified. Traditional purification methods use activated carbon boxes for adsorption. However, the moisture in the steam can clog the adsorption pores of the activated carbon. Also, because the steam flow direction is constant, it is always in contact with the active side, which can easily lead to adsorption saturation and reduce the purification effect. In this invention, activated carbon is placed in the purification box 5. When steam enters the purification box 5, it first comes into contact with the condenser plate 33 for liquefaction, reducing moisture and preventing excessive moisture from crowding out the adsorption pores of the activated carbon. Secondly, by fixing a first servo motor 51 on the purification box 5, the auger 52 is fixedly connected to the output shaft of the first servo motor 51. The first servo motor 51 drives the auger 52 to rotate, which can rotate the activated carbon, allowing different sides of the activated carbon to come into contact with the extracted air, thus improving the purification effect.

[0037] Example 2: Please refer to Figure 5 , Figure 9 and Figure 10 A heat exchange pipe 61 is fixedly installed inside the outer shell 13, and fins 62 are fixedly installed inside the heat exchange pipe 61, with the fins 62 sleeved on the outer surface of the suction pipe 22.

[0038] A third fan 6 is provided at one end of the heat exchange pipe 61, and a second air distribution pipe 63 and a third air distribution pipe 64 are provided at the other end. The second air distribution pipe 63 and the third air distribution pipe 64 are located on the upper and lower sides of the unloaded mold 11, respectively.

[0039] It also includes a water collection assembly, which includes a first water collection module and a second water collection module. The first water collection module includes a water collection tank 7 fixedly installed on the outer shell 13. A first gear 72 is provided on both sides of the inner cavity of the water collection tank 7. A second gear 73 is meshed on one side of the first gear 72. A rotating roller 74 is fixedly installed between the two first gears 72 and the two second gears 73. An absorbent cloth 75 is provided on the rotating roller 74.

[0040] The second water collection module includes a driven member 8 located on one side of the inner cavity of the water collection tank 7. A holding box 81 is fixedly installed on the top of the driven member 8. A sponge 82 is placed in the holding box 81. A rack 84 is meshed at the bottom of the first gear 72. A power rod 85 is fixedly installed at one end of the rack 84. A drive member 86 is fixedly installed at the end of the power rod 85 away from the rack 84.

[0041] Both the follower 8 and the container 81 are wedge-shaped, and the inclined surfaces of the follower 8 and the container 81 fit together.

[0042] A groove is formed in the middle of the actuator 8, and a third through groove 83 is formed at the bottom of the container 81, with the third through groove 83 located above the groove.

[0043] Based on Example 1, during the water cooling process, the sprayed water droplets will drip and splash onto the mold and chain. When the aluminum ingot is still in the mold, the mold is warm and it is easy to dry the water. However, the water accumulated on the chain will drip down the chain onto the lower side of the empty mold. Although the back of the empty mold is facing upwards at this time, when there is too much water, it is still easy to flow to the front of the mold. When the aluminum liquid is injected next time, if there are water stains on the front of the mold and they come into contact with the high temperature aluminum liquid, a violent reaction is likely to occur, which poses a safety hazard.

[0044] In this invention, if water dripping onto the mold 11 during the cooling process is not dried by the high temperature of the aluminum ingot after the aluminum ingot is unloaded, the mold 11 will enter an unloaded state and pass through the lower side of the conveyor line. Since the second air distribution pipe 63 and the third air distribution pipe 64 are located on the upper and lower sides of the unloaded mold 11 respectively, and the bottom of the second air distribution pipe 63 and the top of the third air distribution pipe 64 are provided with second through slots 65, when the air entering and exiting the third fan 6 passes through the fins 62, the heat generated by the steam heating the suction pipe 22 will be absorbed by the fins 62, thereby heating the air by the fins 62, so that the hot air is blown out from the second through slots 65 to dry the upper and lower sides of the unloaded mold 11.

[0045] Furthermore, in this invention, water dripping from the conveyor chain 1 is collected and blocked by a water collection tank 7, which is fixedly installed on the outer shell 13 and located above the empty mold 11. The width of the water collection tank 7 is greater than the distance between the two ends of the conveyor chain 1, so that the water dripping from the conveyor chain 1 can be collected and prevented from falling onto the empty mold 11.

[0046] The aluminum ingot production process involves injecting molten aluminum into a mold via an aluminum distributor. The mold is integrated onto a conveyor chain. The aluminum ingot is shaped by cooling and then unloaded and stacked by a palletizing robot, thus realizing an automated production line for conveying, cooling, shaping, unloading, and palletizing.

[0047] Furthermore, before water cooling, aluminum ingots need to undergo natural cooling to achieve initial shaping before being sprayed for accelerated cooling. Natural cooling takes time. Since the conveyor chain 1 operates continuously, the aluminum ingot production line is relatively long, and factory space is limited. To extend the production line, it is designed as an upward-sloping, wave-like structure, thus increasing its length. Water cooling requires multiple spray stages, and the spray pipes are typically integrated in a nearby area, leaving sufficient space for drying and conveying. This facilitates drying of the aluminum ingots after the mold 11 has cooled, using the high temperature of the ingots. Consequently, some cooling water pipes will be located at the inclined position of the conveyor chain 1. (Refer to the instruction manual for details.) Figure 3 ;

[0048] The way cooling water drips from the inclined conveyor chain 1 differs from that from the horizontal conveyor chain 1. On the horizontal conveyor chain 1, water accumulates until it drips, and the dripping area is the splash range of the cooling water. On the inclined conveyor chain 1, due to the inclination, the water first flows downwards along the conveyor chain 1, and then drips after accumulating sufficient weight. The dripping area is near the point where the weight of the water droplets reaches its limit. Compared to the larger and slower dripping area on the horizontal conveyor chain 1, the dripping area on the inclined conveyor chain 1 is smaller and faster. In this invention, the changing shape of the water collection assembly can flexibly adapt to the two different dripping methods, better achieving the purpose of water collection.

[0049] For water collection on the horizontal conveyor chain 1, an elastic rope 76 is fixedly connected to one end of the absorbent cloth 75, and the other end of the elastic rope 76 is fixedly connected to the surface of the water collection tank 7. This allows the absorbent cloth 75 to unfold and collect water droplets, preventing splashing when the water droplets come into contact with the water collection tank 7, as shown in the instruction manual. Figure 9 For the water collection of the inclined conveyor chain 1, a second servo motor 71 is fixedly installed on the outer surface of the water collection tank 7. The output shaft of the second servo motor 71 is fixedly connected to the first gear 72. By starting the second servo motor 71, the first gear 72 is driven to rotate, so that the first gear 72 drives the second gear 73, thereby driving the rotating roller 74 to rotate. The rotating roller 74 stores the elastic rope 76. When the first gear 72 rotates, it can drive the rack 84, so that the rack 84 drives the power rod 85 to move, so that the driving member 86 drives the driven member 8, so that the driven member 8 moves upward, and then the sponge 82 contacts the inclined conveyor chain 1, which can absorb the water that has flowed and accumulated due to the inclination, and discharge it into the water collection tank 7 through the third channel 83. The width of the first gear 72 is greater than that of the second gear 73, so that it meshes with the rack 84.

[0050] It should be noted that when collecting water at the horizontal section of the conveyor chain 1, the second servo motor 71 can be started to drive the rotating roller 74 to rotate and collect the absorbent cloth 75. During the collection process, the diameter of the rotating roller 74 increases, causing the two rolled absorbent cloths 75 to squeeze each other, achieving the purpose of squeezing out water. Then, the second servo motor 71 is started again to unfold the cloth, improving the water absorption effect of the absorbent cloth 75. When collecting water at the inclined section of the conveyor chain 1, the second servo motor 71 can be started to further raise the sponge 82, so that the sponge 82 and the conveyor chain 1 can be collected together. The compression between the conveyor chains 1 causes the sponge 82 to deform, squeezing out the water in the sponge 82 and allowing it to flow into the water collection tank 7 through the third channel 83, thus improving the water absorption effect of the sponge 82. This avoids the problem of reduced water absorption and splashing caused by excessive moisture content in the absorbent cloth 75 and the sponge 82. In addition, sliders can be provided on the surfaces of the driven member 8 and the rack 84, and grooves can be opened in the water collection tank 7 to limit and guide their movement. Holes can be opened in the water collection tank 7 to connect to the drain pipe for continuous drainage.

[0051] More specifically, for the steam treatment of the inclined conveyor chain 1, since the outer shell 13 is installed at an incline to avoid interference with the conveyor chain 1, the purification box 5 is also in an inclined state. The activated carbon inside will also slide downwards due to the incline and be difficult to move. In this invention, the auger 52 can not only drive the activated carbon to turn over, but also move it, so that the activated carbon can constantly change its position, thereby avoiding the problem that the activated carbon is difficult to move and will always adsorb, resulting in saturation of the adsorption pores and reduced purification effect.
